For the video display developer LCD panels are available in many sizes and resolutions, they are also available with many choices of maximum brightness. The following considers the topic of LCD panel brightness, the choices, the methods for adjusting brightness and some brightness adjustment scenarios.

LCD panels are generally rated as to their maximum brightness level which is expressed in Nits, it is equal to Candela/sqm (cd/m2), and this will be at a particular color temperature as noted in the specification, usually 10,000 K. In terms of a practical understanding, the following is a rough guide:

Outdoor displays range from a low end of 700 nits to typically 1,000 or 1,500nits and up with 2,000~2,500nits and even up to 5,000nits seen with some models. This may include standard LCD panels, custom LCD panels as well as custom cut LCD panels.

Virtually all LCD panels have a LED backlight these days, these are powered by an LED driver board. Brightness control via the driver board will be by one of two methods:

PWM (Pulse Width Modulation): This varies the duty cycle of the backlight “on time” – it is predominant in modern LCD panel LED backlight designs to enable support for digital brightness controls.

Analog: Uses a simple variable voltage to adjust brightness, for example this might be a dial or slider type potentiometer / variable resistor. To see how to enable analog backlight adjustment visit: https://www.digitalview.com/blog/brightness-adjustment/

One of the advantages of LED for the backlight is the range of adjustment that is possible, however it is important to note that the range varies significantly from model to model. Some industrial panels can be turned to very low light levels making them suitable for use in special environments such as at night. Lower cost panels limit the range of brightness to what might be required for typical usage, whereas panels with full range dimming from full off to full on require more complex backlight drivers.

Backlight lifetime: Many LCD panels have a backlight lifetime rating of 50,000 hours (typically measured to half brightness), this can be extended by running the LED backlight at a lower brightness level. Some panels may only offer 30,000 hours as a lower cost solution while other panels may offer up to 100,000 hours for high end applications.

An LCD panel backlight may be constructed so the LED’s are mounted directly behind a light guide diffuser, or they may be mounted along one or more edges of the light guide.

Active backlight: This is a function of some LCD panel backlights to automatically adjust the backlight brightness in response to the image. For more advanced systems there is an LED array making up the LED backlight, this adjusts the brightness in areas localized to the image being shown. This can greatly enhance the brightness across the display and is being used primarily with video, for example on consumer TV sets. It is not useful to all image types, for example a spreadsheet or content like maps or data is not likely to benefit.

Local dimming: Some LCD panels with direct LED may support local dimming so the LED’s are dimmed in response to the image close to them. This will not be at the same resolution as the LCD panel itself but will help greater contrast over the display by enhancing the brightness in bright areas of the image and darkening the image in dark parts of the image.

For the LCD monitor manufacturer it is important to consider that any covering over the LCD panel will reduce the brightness. For example the protective glass over a digital signage display, or a touch screen, or a semi-silvered mirror. So if a specific brightness is required the measurement should be taken with these in place.

There are various relatively low cost brightness meters available, typically in the couple of hundred dollars range. It is difficult to comment on the accuracy of these but we have found them to be within 5% of each other, though more importantly they do appear to be quite consistent in measurement so good for measurement comparisons. For more accurate measurement there are light meters from companies such as Minolta that can be calibrated, the cost may run into several thousand dollars.

Examples of light meters costing a few hundred dollars include SpyderX by Datacolor (needs a PC), a handheld meter is the SM208 by Sanpometer (search SM208 meter). Note: Many light meters, including smartphone apps, will be meters used for photography and not give readings in nits (or candelas). LCD panel specifications are typically measured using nits.

PWM and Analog: Most Digital View LCD controllers support PWM and Analog as a method for adjusting the backlight brightness level (this is noted in the column headed “Other” on the controller board summary table: https://www.digitalview.com/controllers/lcd-controllers-home.html. Also see https://www.digitalview.com/blog/brightness-adjustment/ for a guide to using a dial or slider type variable resistor to adjust the backlight.

Ambient light sensor: The backlight is adjusted for brightness or powered off depending on ambient light conditions. This uses a light sensor attached to the LCD controller board, see https://www.digitalview.com/blog/light-sensor-app-note/ for more details.

The specifics of the backlight control are documented separately for each LCD controller model (product summary here) in the product manual available for download on the product page.

Note: There are two ways to adjust the perceived brightness of a LCD panel or LCD monitor, the backlight and the black-level. Very often, particularly in the past, the monitor brightness setting adjusted the black-level, this adjusts the LCD but not the backlight.

Color, color temperature etc: In addition to adjusting the brightness other settings may be adjusted as well. For example the color temperature or for example a switch to green monochrome for night vision.

Night-safe lighting (update) : Dual-rail backlights can also be supported. These special backlight enable normal brightness and extreme low level brightness with custom night-safe lighting. Contact us for details.

Note: We have a blog on methods for implementing an ambient light sensor with Digital View LCD controller boards to automatically adjust the backlight or system power, see: Ambient Light Sensor

Update March 2019: Most of the above remains unchanged except for the increased availability of high bright LCD panels of around the 1,000 nit to 2,500 nit range. AUO for example has a number of large size LCD panels with 1,500 nit brightness for the digital signage market. Tianma has panels under 20″ with 1,000 nit to 1,500 nit brightness for various outdoor applications.

The other change is that high bright panels are now increasing edge-lit, this makes the panels thinner and these panels tend to use less power than the previous models. One of the benefits for monitor designers is easier heat management and reduced overall display system costs.

For the ABL calculation to be significant, it should correspond to the way we perceive different luminosity levels. The eye is much more sensitive to small changes in luminosity in a dark environment than in a bright one. Although the measured change in luminosity may be the same, the brighter source is better because we don"t notice the change in brightness as much. Essentially, if a screen goes from 25cd/m² to 20 cd/m², it"s more noticeable than a screen going from 100 cd/m² to 95 cd/m². This linearization is done with the PQ EOTF, as you can see below.

PQ is a function that relates luminosity with noticeable differences in brightness. When the PQ curve is divided into 4096 segments (12-bit), there are smaller steps that relate to the change in brightness; the horizontal dotted lines represent each step, and as you can see, the first step in each segment represents a higher change than the last segment. We use this to linearize all of our luminosity measurements for this test, ensuring the ABL best represents what"s seen.

You should set your TV’s backlighting/brightness to whatever level looks best in your room. Generally, you should keep it a bit dimmer when watching in a dark room and make it very bright in a room with lots of light. Adjusting the luminance of the TV doesn"t affect picture quality, so you can easily put it to whatever setting you like.

Backlight/Brightness/OLED Light:These settings are what increase the luminosity. The majority of LED TVs call it Backlight, but Samsung and Sony use Brightness. On OLEDs, it"s usually called OLED Light, but the Vizio OLED 2020 has a Luminance setting. Whatever they"re called, these settings are meant to adjust the luminance and are the best setting to use to get the brightest image possible.

Brightness:Opposite of contrast, the brightness setting controls the black level, and on some TVs, the setting itself is called "Black Level". Decreasing it makes blacks darker, but that means you can easily lose details, so we don"t recommend changing it.

Gamma:Gamma affects the brightness of the overall scene, but it doesn"t have an impact on the luminosity. In our testing, we want TVs to follow a gamma target of 2.2; anything higher results in a darker overall image and lower means the image is brighter. Some TVs have gamma settings, so you should change it to your liking if you notice the overall image is too dark, even if you have the backlight at its max.

Eco Mode/Light sensor: Some TVs use a sensor to detect how much light is in the room and adjust the backlight accordingly. It can be helpful, but it can also change the brightness often while you"re watching, so it"s best to turn it off.

A TV"s brightness indicates how bright images can get on the screen. It matters most if you watch TV in a well-lit room, as you want your screen to get bright enough to combat glare; otherwise, it may be hard to see. We test for a TV"s brightness to know exactly how bright it can get, but also to see if it remains a consistent brightness level across different content. If you watch TV in dark rooms, then brightness shouldn"t be something to worry about.

We test peak brightness for both SDR and HDR. We take measurements of a custom real scene peak brightness video and multiple slides, ranging from 2% to 100% coverage of the screen. From those measurements, we also calculate the monitor"s ABL, or Automatic Brightness Limiter, which is a measurement of how much the sustained brightness of the screen changes with different window sizes.

We start by warming up the display by displaying a series of video clips for at least 30 minutes. Our SDR measurements are all taken from a PC, using our calibrated settings, but with the brightness at "Max". If the monitor supports local dimming in SDR, we set it to our recommended setting based on the results of our "Local Dimming" test. We take our measurements using a Colorimetry Research CR-100 Colorimeter, using Octave to gather the results for the peak and sustained window tests and CRIapp and Excel for the Real Scene measurements.

We measure the real scene brightness using a custom video clip. We measure the brightness of the lamp at the upper left corner of the screen for 30 seconds using a CR-100 colorimeter. The real scene clip is designed to be more representative of real-world usage than the window tests since most people don"t watch test slides all day long. Since this measurement is the closest to the real user experience, it makes up the bulk of our SDR Peak Brightness score. A peak brightness above 300 cd/m² is considered good, and enough to overcome glare in most instances, but you might need higher if the monitor doesn"t handle reflections well or if there"s direct sunlight shining on the screen.

We perform the SDR peak and sustained brightness tests to see whether there"s any brightness variation when displaying different scenes. The peak windows show how bright the monitor can get in the 2%, 10%, 25%, 50%, and 100% windows when the image is only displayed for a short time. The sustained windows show the brightness in the same windows, but for a longer period. Although it isn"t as indicative of real-world usage as the real scene measurement, the peak and sustained windows show exactly how bright the display can get and whether there"s dimming in any particular window. Generally speaking, a monitor with consistent brightness is best, especially when image accuracy is required, like content creation.

The HDR real scene test is the same as in SDR. We use an HDR version of the same video clip, which gives us a more realistic representation of the monitor"s brightness in HDR content. We set the monitor to the appropriate HDR mode with brightness at max and enable local dimming (if applicable). We play the video clip and focus on the lamp in the upper left corner to take the measurement. Most games allow you to adjust the dynamic range of the entire engine, so a real scene peak brightness over 550 cd/m² is considered good enough for gaming in HDR. Movies are a bit different, though, and for a true cinematic HDR experience, a peak real scene brightness of at least 1,000 cd/m² is best. HDR movies can still look good on displays with lower peak brightness, but bright specular highlights don"t stand out as much as they should.

Automatic Brightness Limiter, or ABL, is a feature that changes the brightness according to the content displayed on the screen. It"s intended to prevent damaging internal components when displaying large, bright images. The ABL test shows the amount of brightness deviation in the sustained window slides. We calculate the coefficient of variation using the measurements in the sustained windows. Because the human eye is better at noticing luminosity changes in a dark environment than in a bright one, we first linearize the measurements for any noticeable differences in luminosity using the Perceptual Quantizer (PQ) EOTF, making the results more representative of what"s perceived. For example, a change of 20 cd/m² is much more noticeable when viewed in the dark than in a bright setting. Most monitors have low or no ABL, so this test accounts for a small percentage of the overall score.

We also test for the lowest possible brightness the monitor can reach in SDR. It"s done with a checkerboard pattern, using our recommended settings in SDR. We decrease the brightness setting to its lowest setting and measure the brightness of the screen in the center. This test is important if you plan on using the monitor in a completely dark environment and are sensitive to light. Most monitors should be well below 100cd/m² at their lowest setting, but some people prefer to set their monitors as low as 10-20cd/m².

There"s not much that you can do to improve a monitor"s peak brightness other than increasing the brightness and choosing the picture mode that gets the brightest, although these picture modes tend to sacrifice image accuracy. Some monitors have an "Eco mode" intended to reduce power consumption, so you need to ensure that it"s disabled if visibility is an issue. 300 cd/m² is usually enough to provide good visibility in most environments, but if there"s sunlight or the monitor doesn"t handle reflections all that well, then you might want to find one that"s closer to 400 cd/m² or brighter. As for HDR, the brighter the better, although there are very few monitors that get bright enough for a true HDR experience. Lastly, when looking at specifications, the advertised brightness can be in "cd/m²" or in "nits", which are the same thing.

Except for some budget options, most monitors get bright enough for use in well-lit environments. However, keep in mind that brightness can vary slightly from one unit to another, and the manufacturer"s advertised brightness is an estimate that tends to be on the optimistic side. If you"re in a room with sunlight or want a better HDR experience, then you should specifically check the monitor"s SDR and HDR peak brightness measurements to make sure it satisfies your needs.

The first steps in LCD technology began in 1897, when Karl Ferdinand Braun, a physicist and inventor, built the first cathode ray tube. This tiny tube would allow the first televisions to be built, creating an industry that has progressed quickly since its inception.

With the advances in technology, besides the creation of displays with different shapes and availability, ultra high brightness LCDs displays have emerged, an ideal solution developed for outdoor, semi-outdoor and window/glass applications.

Ultra high brightness LCDs are suitable for bright outdoor environments, even under direct sunlight, and these can be used 24/7, providing high contrast and excellent colour reproduction with a clear and visible image. This display offers a good solution for applications in environments with high sunlight exposure, ensuring that not only can its contents be seen, but also noticed, thus being a great competitive advantage.

Despite their merely similar characteristics, ultra brightness LCDs and high brightness LCDs are different when it comes to the intensity of their brightness.

The lass with “micro-etching” or anti-reflective treatment almost completely eliminates reflections and is suitable for use in ultra high brightness LCDs.

The unique properties of anti-glare glass allow these annoying elements to be filtered out and reduced, enhancing the experience through a Ultra High Brightness LCD display.

It is important to invest in ultra high brightness LCDs, a solution for high ambient light incidence applications for outdoor, semi-outdoor and window-facing applications.

Ultra high brightness LCDs can be easily viewed in direct sunlight, such as window displays or outdoor cases, without the interference of glare from glass and surrounding reflections;

In this sense, investing in ultra high brightness LCDs is an added value for the projection of content since it ensures that no visitor will remain indifferent to the content that is being transmitted, facilitating and improving communication. All this will allow a great competitive advantage for the companies/brands which choose this kind of displays.

Therefore, PARTTEAM & OEMKIOSKS recommends ultra high brightness LCDs in order to improve the communication between the brand/ establishment and the visitors.
