Watching TV Displays at Night

For over 50 years people have been watching TVs at night – often very late right before going to bed. In fact, many also have a TV in their bedroom and watch from bed, before and even after turning out the lights. Many people consider TVs a sleep aide to help them relax before falling asleep. But recent research indicates that this is far from the whole story...

 

One very important point to bear in mind in the discussions below is that looking at TV is generally a passive activity for watching photographic video content, and the TV display is typically 8 feet away or more.

 

Watching Smartphone, Tablet, Laptop and Computer Monitor Displays at Night

With increasing frequency people are spending more and more time in front of their Smartphones, Tablets, Laptops and Computer Monitors at night, and some suspect that the display could be affecting their ability to fall asleep afterwards. But most of that time is spent reading and writing text on a brightly lit white screen, which is very different from watching TV picture content. Some of this is work, and some texting and Emails may be friendly fun, but they all require considerable active rather than passive participation when watching TV content. And then there is gaming, which is generally an even more intense experience. An active mind takes a while to settle down and relax, so adjusting the display alone may not help much in falling asleep soon afterwards (other than possibly from a placebo effect). But many people are now also watching traditional TV content on their devices via streaming and downloads. In that case the display needs rather different settings than when they are reading on the same display at night.

 

In addition to the differences in screen content, these smaller devices are often set very bright and are viewed from much closer distances at night, often down to 8 inches for Smartphones, 12 inches for Tablets, and 20 inches for Laptops and Monitors. It’s easy to see how just these two factors alone could make it harder to fall asleep. So it would seem that by just applying some conscious behavior modification and properly adjusting the display Brightness should correct or at least significantly improve these issues. But there is much more to this...

 

Watching Displays at Night Affects Sleep

With the rapidly increasing use of these displays, particularly at night, vision and sleep researchers discovered that watching a display at night can not only make it harder to fall asleep (up to 1.5 hours longer), but then the quality of sleep during the night is also reduced, and it carries over into the following morning with reduced alertness. So improperly watching a display at night can lead to sleep disorders, which in turn can lead to a wide variety of serious psychological and medical issues, including evidence for increased heart attacks and a higher risk of some cancers, which have been documented in sleep research studies.

 

So Watching Displays at Night requires both consumers and manufacturers to make some important changes and adjustments...

Introduction and Science Background

In this first section we outline the basic issues and science.

 

Blue Light at Night

While exposure to any significant amount of light at night can affect sleep, the color (and spectrum) of the light is a very important factor. For example, astronomers and people that work in darkroom environments know that using Red lighting will not affect their eye’s dark adaptation. It turns out that Blue light is what primarily controls the eye’s response, but it isn’t all Blue light but rather only a specific portion of the Blue spectrum.

 

Some recent research has identified the particular spectral region of Blue light with wavelengths in the range of 460-490nm (received by melanopsin receptors in the eye) that causes a problem with sleep for late-night display users. The melanopsin cells control pupil dilation and melatonin release from the pineal gland, which is responsible for regulating the circadian rhythm. Watching any display at night can upset the body’s natural day and night cycle. This 2014 article from the Proceedings of the National Academy of Sciences is an example of some excellent research on this topic.

 

The wavelength range that has been identified and measured varies between research studies (which isn’t surprising because of the difficulty of lab testing vision and sleep in humans). The 460-490nm range that we adopt in this article covers most of the studies, but some recent studies indicate that it may extend further into a portion of the Green part of the spectrum above 500nm – we’ll also discuss that below. So next we need to examine the display’s light spectrum...

 

Light Spectrum for Displays

Virtually all current displays use three Primary Red, Green and Blue Colors to produce their entire range of on-screen colors. This includes both LCD and OLED displays. This always results in three well defined peaks in the display’s light spectrum.

 

Figure 1 below shows the spectra for the iPad Pro 12.9, iPad Air 2, and iPad mini 4, which are representative of current LCDs that have White LED Backlights (including the iPhone 5 and 6). The latest iPad Pro 9.7 has a slightly different color gamut and spectrum, so we have not included it here for clarity, but all of the issues and conclusions remain the same.

 

The Blue 460-490nm spectral range is marked in light gray in the Figure below. The proportion of light energy in this range is considerably greater than in the solar spectrum, which is why displays can interfere with sleep after night use.

 

Because of the fixed broadband peak for the display’s Blue primary spectrum, the only way to significantly reduce the light energy in the 460-490nm spectral range is to significantly turn down the brightness for the entire Blue Primary, which is the tall spectral peak on the left. This reduces the color gamut and gives all images a significant Yellow color cast because they are lacking Blue (since Yellow is the complementary color to Blue). Just slightly turning down the Blue brightness, which is what a number of Apps do, is not likely to have a significant effect other than helping somewhat together with some placebo and the benefits of conscientious user modification of their viewing behavior.

 

For this approach to actually work the display needs to produce a rather significant Yellow screen appearance. In the future, displays can (and will) be produced with a modified light spectrum that minimizes the light energy in this troubling Blue spectral range, reducing or eliminating the need for a Yellow cast while still maintaining a full color gamut. For LCDs that will mean switching away from the White LEDs that are used in the current Backlights. We’ll show an impressive example for an LCD with Quantum Dots below.

Watching Displays at Night

To improve existing displays for watching at night so that they don’t adversely affect sleep requires not only significantly reducing the display Brightness, which is easy, but then making sure that the least possible amount of Blue light in the 460-490nm spectral range is being emitted by the display or is blocked in some other way. There are several approaches for doing this...

 

Tinted Glasses

One approach that has been tried for reducing or blocking the display’s Blue light is by using Yellow tinted glasses (or Red or Orange tinted glasses if you believe that Green light is also an issue). The problem is that the display light spectrum has strong well defined peaks for Blue, Green and Red, so the common (affordable) broadband color filters used in glasses and related filter applications are not selective enough, so they don’t work well for use with displays (unless they are manufactured with a very high optical depth resulting in very low transmission). High-end optical notch filters will work but they are very expensive.

 

Adjusting Existing Displays at Night

It turns out that the smartest and best way for modifying and adjusting the display’s Blue light output for existing displays at night is by using the display’s own hardware and modifying the software.

 

f.lux for Displays at Night

The first software application to work on the Blue light issue for displays at night was developed by f.lux back in 2009. They have remained a major innovator in this area and the f.lux website has lots of information on this evolving topic. They provide free downloads of the f.lux App for OSX and Windows, and also for Linux and some Android devices. Surprisingly, Apple doesn’t as of yet allow f.lux into the App Store for iOS devices like iPhones and iPads.

 

Apple’s Night Shift

Apple’s introduction of a new adjustable night mode for displays called Night Shift in iOS 9.3 for recent model iPads and iPhones is a major industry-wide and worldwide development in getting this important issue recognized and appreciated by consumers, manufacturers and researchers. Apple’s enormous market power not only brings attention to this important issue but it will certainly require all other manufacturers to respond in kind...

 

Night Shift is implemented with a user adjustable slider in Display Settings that reduces the display Brightness and modifies the display spectrum by changing the relative balance of the Primary Colors as we have discussed above and will examine in detail below.

 

The Night Shift slider varies the magnitude of the effect from a minimum minor change at its extreme left to a maximum major change at the extreme right. It not only decreases the Blue Primary (producing a Yellow color cast) but then continues further by also increasing the Red Primary (moving to an Orange color cast beyond Yellow).

 

A shortcoming of Apple’s Night Shift is that it operates in the same way for all content, including for reading text and watching picture content – we explain below why different display settings are needed. Note that the single Night Shift setting turns On and Off at fixed (local) times and that the Night Shift slider is located in a 3rd level menu in Settings, which makes it cumbersome to reach and change.

 

This article is not a review of Night Shift or f.lux. We’ll explain below in our Recommendations for Consumers and Recommendations for Manufacturers how we believe displays should function for watching at night.

 

Improving Future Displays for Watching at Night

All of the methods we have been discussing are for dealing with the light spectrum in existing displays. But the innovative and high-tech way to improve displays for watching at night is for manufacturers to change the display’s internal native light spectrum to eliminate or at least significantly reduce the problem areas that affect melatonin production and sleep.

 

For LCDs that will mean switching from using White LEDs, which have excessively broad rolling spectra, and instead using technology that produces sharp Primary spectra that can be tuned to avoid the part of the spectrum that affects melatonin production and sleep. All of this also needs to be applied to standard TVs because they are still by far the largest audience for displays at night. We will discuss these issues under Light Spectra for an Advanced LCD with Quantum Dots and Recommendations for Manufacturers below.

 

Displays for Cars at Night

A really useful inverse application of displays at night is to turn up the Blue light component for the increasing number of displays now used in cars (and also plane cockpits). That will not only reduce the likelihood that the driver becomes tired, sleepy or falls asleep, but it will also improve alertness and memory. So it could provide an important improvement in automobile safety, since there are currently much higher accident rates at night. Most cars now come with several displays including a dashboard display in the driver’s field of view and a center console display that can be used to implement this effect.

 

 

Light Spectra for Displays at Night Using Apple’s Night Shift

As we have discussed above, the best way to improve watching displays at night for existing displays is to change the relative balance of the display’s Primary Colors, particularly the Blue Primary, which includes the 460-490nm spectral region that affects melatonin production and sleep.

 

Figure 2 below has the spectra for the Apple iPad Pro 12.9, first with Night Shift turned Off (the same as in Figure 1 and also for any LCD display without a night mode), and then with Night Shift turned On and the slider at the Middle (default) setting, and also with the slider at its Maximum setting. The Blue 460-490nm spectral range is marked in light gray in the Figure below.

 

The Night Shift slider settings also change the display Brightness, but we recommend that you then manually adjust the Brightness slider for your own optimum viewing comfort. For the Figure below we removed the Brightness variations so that the spectra for the three settings could be compared directly. The Night Shift also boosts the Red Primary, pushing the screen beyond a Yellow color cast and into Orange, but that is not a factor for the Blue light effect that we have been examining.

 

Using Night Shift the amount of light in the 460-490nm spectral region that affects melatonin production and sleep is reduced to 57% for the Middle setting and 42% for the Maximum setting compared to the display with Night Shift Off.

 

This is roughly the same degree of improvement as an Advanced LCD with Quantum Dots that we examine below, but with Night Shift the iPad Pro 12.9 now has a strong Yellow to Orange color cast, a reduced Color Gamut, and very large Color Errors for picture content. However, the Advanced LCD with Quantum Dots will maintain the same White Point, Color Gamut and Color Accuracy with roughly the same Blue light reduction in the 460-490nm spectral region

 

Note that the iPad Pro 12.9 results apply to essentially all current LCDs with White LED Backlights. We examine this further below.

Recommendations for Consumers Watching Displays at Night

Below are our suggestions and recommendations for watching displays at night for consumers. Bear in mind that some of our recommendations are not currently available in software. Some important future modifications in both display software and hardware will need to be implemented by the manufacturers, which we discuss under Recommendations for Manufacturers in the next section below.

 

1. Viewing Distance:  Try not to hold the display too close to your eyes. That will depend on the display size and whether you are reading and typing.

 

2. Room Brightness:  As the evening gets later most people know to reduce the overall room lighting. An important benefit is that this will then let you further reduce the Brightness of the display and still comfortably see the screen. Note that the room lighting also affects the circadian rhythm, and that fluorescent and LED lighting has a much stronger Blue component than traditional incandescent lighting.

 

3. Display Brightness:  Turn down the display Brightness considerably. Most displays now come set for 400 nits or more. For watching displays at night 100 nits or even less is all that you need at night. That will lower the amount of light (including Blue light) by a factor of 4 or more. You don’t need an instrument to measure it, just lower the brightness as much as is comfortable.

 

It is very important for consumers to be able to easily and quickly adjust the display Brightness whenever they want. Currently it is rather cumbersome to adjust the Brightness of most displays – for all mobile displays we recommend that the Volume up and down buttons should adjust the display Brightness when audio isn’t playing. TV Remotes also need a convenient way to adjust Brightness. Don’t rely on Automatic Brightness Controls for mobile devices and TVs because they generally don’t work well, which we discuss in the next section for manufacturers below.

 

4. Black Background for Reading:  If you are reading on a screen that has a white background, which gives off the maximum amount of display light, then consider switching from Black text on a White background to White text on a Black background. That will reduce the amount of light from the display considerably, by a factor of 10 to 1 or more. This is by far the single most important recommendation for reading on a display at night.

 

By keeping the Brightness of the text nice and low it should actually be easier on the eyes. That is breaking with the traditional reading on paper analogy, but since displays produce their own light it’s time to consider using them in this way with a black background at night. We explain how to quickly try this below. But if it’s not for you, then skip to number 5 below.

 

All manufacturers should make it easy to switch in and out of these two background modes, which should be implemented as an OS service for all applications that want to display text. This is something that is almost never provided and should be a standard option for all display products. And as an added plus, using a Black background also improves screen readability in high ambient light (and significantly reduces power consumption for OLED displays).

 

Together with the factor of 4 in step 3 above, that will reduce the amount of light (including Blue light) produced by the display by a factor of 40 to 1 or more. Steps 1 to 4 may be all that you need to fall asleep naturally after reading on a display at night.

 

For both Apple and Android devices the only built-in way for switching from Black text on a White background to White text on a Black background is by using a menu option called Invert Colors or Negative Colors (under Accessibility in Settings). However, that makes the screen look scary with picture content.

 

5. Yellow Text for Reading:  If you are still having trouble sleeping after reading, remember that an active mind takes a while to settle down and relax, so adjusting the display alone may not help much in falling asleep soon (other than possibly a placebo effect).

 

The next step should be switching to Yellow text by turning off or at least significantly reducing the display’s Blue primary color. Yellow is the complementary color to Blue so the screen takes on an increasing Yellow cast as Blue is reduced. Apple’s Night Shift will let you control the amount with a slider that adjusts the strength of the display’s Blue Primary. Following all of the above steps should solve or help falling asleep after reading on a display at night.

 

6. Watching TV Picture Content at Night:  TV content is very different from reading on a display because you are watching photographic style picture content rather than reading a mostly bright white screen, so the display needs rather different settings than when reading on the same display at night.

 

There are two important factors for TV picture content: first, the average screen Brightness (Average Picture Level APL) for most picture content is typically quite low, around 20% rather than close to 100% for a bright white screen. That provides an automatic 5 to 1 screen Brightness reduction. Together with the factor of 4 improvement in step 3 above, this will reduce the amount of light produced by the display by a factor of 20 to 1 or more. Second, the images typically have a very wide mixture of colors with proportionally much lower overall Blue light than White because typical photographic style content has mostly warm colors from Greens to Yellows to Oranges to Reds. This will further reduce the amount of Blue light from the screen by at least another factor of 2.

 

The resulting total factor of 40 to 1 or more reduction may be all that you need to fall asleep naturally after watching TV picture content on a display at night.

 

If you are still having trouble sleeping after watching TV picture content, then the next step is to consider reducing

the display’s Blue primary specifically for picture content. That will not only impart a Yellow color cast to the screen, but it will also distort all of the colors in the picture, which many people may find unacceptable, so it should be a last resort.

 

7. Viewing Mixed Reading and Picture Content:  A large fraction of all internet and multimedia content contains both text and picture content (photos and videos) mixed together. As we have explained above both types of content should have different Brightness settings, different background settings (Black for text at night), and different settings for the level of Yellow (from reducing the Blue Primary). This is especially important when they appear together in mixed content. The OS and App know what kind of content is being drawn on the screen so it will be automatically implemented on-screen once the OS provides this functionality.

 

8. Setting Display Themes by Time and Location:  If you regularly watch certain content at night in certain rooms or locations (like your living room, bedroom, or office) then saving and storing all of their display settings under named Themes that are easily selectable will help to customize and semi-automate your watching displays at night.

 

9. Actively Adjusting and Personalizing the Display:  The ability to adjust and personalize the display will reduce visual fatigue and stress, and undoubtedly improve sleep. People that adjust their display and their viewing behavior are likely to also experience a strong genuine placebo boost, but that is also welcome...

 

Consumers should take the time to familiarize themselves with all of the available display controls, and then regularly and interactively adjust and customize them for their particular personal preferences, pleasure and visual comfort. And do this regularly based on the time, lighting, mood and application.

 

Unfortunately most products only provide a single control for consumers to adjust the display – its Brightness. But having several more display controls that are conveniently and quickly accessible (and not buried in some display settings menu) are needed to customize and personalize a product, including adjusting the White Point, the image contrast, the vividness, color gamut and color saturation, and the background and text colors, for example.

 

Last but not least... follow DisplayMate on Twitter to learn about new developments and our upcoming display technology coverage.

 

 

Light Spectra for an Advanced LCD With Quantum Dots

The innovative and high-tech way to improve all displays for watching at night is for manufacturers to change the display’s internal native light spectrum to eliminate or at least significantly reduce the problem areas that affect melatonin production and sleep, while still delivering Blue light so that the display doesn't look Yellow and still provides a full Color Gamut. That will require carefully tuning all future display spectra.

 

For LCDs that will mean switching from White LED Backlights, which produce rolling broadband spectra, to Backlights that include sharp Primary spectra using tunable Quantum Dots, fluorescent films or discrete Blue, Green and Red LEDs.

 

It turns out that a current model Vizio R65 TV with Quantum Dots that produce a very wide Rec.2020 Color Gamut already demonstrates how this is done. In Figure 3 below, the Vizio R65 spectrum (courtesy of Nanosys, which makes the Quantum Dots) has about 35% less Blue light in the 460-490nm region (for the same total Blue Luminance) as the iPad Pro with a standard White LED Backlight, and it remains fairly low up through 510nm. Again, this comparison applies to all LCDs with White LED Backlights, not just the iPad Pro 12.9.

 

The improvement with Quantum Dots is comparable to the improvement using Night Shift on the iPad Pro 12.9 that we examined above, but without a strong Yellow color cast, and maintaining the same full Color Gamut and White Point.

 

More importantly, with this technology manufacturers can actively further improve the spectrum by shifting the Blue Primary to the left and the Green Primary to the right, leaving a nice big hole in the part of the spectrum that affects melatonin production and sleep.

 

Although the Rec.2020 Color Gamut is much wider and more saturated than the sRGB/Rec.709 Color Gamut that is used for almost all current consumer content, standard display digital Color Management can convert all image content to the sRGB/Rec.709 Color Gamut while still using the same widely separated and highly saturated native Rec.2020 Primaries that create the desired hole in the Blue part of the spectrum.

Recommendations for Manufacturers to Improve Watching Displays at Night

Implementing our suggestions for manufacturers below will not only improve the consumer experience and display performance but it can also be a major marketing opportunity for the manufacturers that lead the way.

 

1. White Text on a Black Background Mode:  The product OS needs to provide a convenient, fast and simple way for consumers to switch from Black text on a White background to White text on a Black background. Applications that use OS services to write text to the screen will then display appropriately.

 

2. Easy Access Brightness Controls:  It is very important for the consumer to be able to easily and quickly adjust the display Brightness whenever they want. Currently it is rather cumbersome to adjust the Brightness of most displays. For all mobile displays we recommend that the Volume up and down buttons should adjust the display Brightness when audio isn’t playing. TV Remotes also need a convenient way to adjust display Brightness.

 

3. An Accurate Interactive Automatic Brightness Control:  Automatic Brightness Controls are supposed to accurately adjust the display Brightness based on the measured level of ambient light but they don’t work well on virtually all mobile and TV products. As a result, many (and possibly most) consumers simply turn off Automatic Brightness and permanently park the Brightness at some fixed high level. An Interactive and Adjustable Automatic Brightness Control is particularly useful for watching displays at night. I covered this in detail back in 2010, with an article called BrightnessGate that described “How Automatic Brightness Should Work” including the Interactive feature.

 

4. A Night Mode:  Obviously a Night Mode needs to be provided that not only significantly reduces the display Brightness but also reduces the amount of Blue light in the 460-490nm spectral range emitted by the display as we have discussed above. It should be conveniently adjustable and have different settings for text and picture content, and also allow consumers to save their settings with named Themes based on content and location.

 

5. More Display Controls:  Most manufacturers only provide a single control for consumers to adjust the display – its Brightness. But providing several more display controls will allow consumers to customize the display based on their personal preferences and applications, which will improve customer satisfaction. Important controls include adjusting the White Point, the image contrast (Gamma), the vividness, color gamut and color saturation, along with the background and text colors.

 

6. Improved Display User Interface:  The User Interface for most displays range from not very good to awful. Frequently the display User Interface is awkward, inconvenient, counter-intuitive, plus it is almost always buried inside a multi-level Settings Menu under Displays. All of the display controls need to be easy to access, understand, and adjust.

 

7. Lower Screen Reflectance:  Lowering the screen Reflectance will allow the consumer to use a lower Brightness setting and still conveniently see the display. Most displays have a screen Reflectance between 4.5% to 7%. Our current record holders are the iPad Pro 9.7 with 1.7% and an LG OLED TV with 1.2%. This provides a 3 to 1 or more advantage over most other displays.

 

8. Improving the Blue Spectrum in Future Displays:  The innovative and high-tech way to improve all displays for watching at night is for manufacturers to change the display’s internal native light spectrum to eliminate or at least significantly reduce the problem areas that affect melatonin production and sleep, while still delivering Blue light so that the display doesn't look Yellow and provides a full Color Gamut. That will require carefully tuning all future display spectra. All of this also needs to be applied to standard TVs because they are still by far the largest audience for displays at night.

 

The key will be adopting sharp spectra for the Blue and Green Primaries. For LCDs that will mean switching from White LEDs, which produce rolling broadband spectra, to Backlights that include sharp spectra using tunable Quantum Dots, fluorescent films or discrete Blue, Green and Red LEDs. OLEDs already have narrow spectra but will benefit from shifting the primaries by modifying the OLED materials.
