lcd screen in sunlight quotation

Crystalfontz has a large selection of sunlight readable displays. We carry both graphic sunlight readable LCD displays as well as character sunlight readable LCD displays.

A transflective lcd offers lower power for high ambient light applications, very good sunlight readability, and good balance between indoor and outdoor readability. They perform better under all lighting conditions, especially direct sunlight.

A reflective lcd display has polarizers that are basically a mirror that sits behind the LCD glass reflecting all the light from the sun and redirecting it back towards the user. The brighter the light, the easier it is to read. The downside to a reflective polarizer is that in dark environments, you cannot put a backlight behind it. The reflective polarizer will block any light from reaching the user. If you must have a backlight, you may need to add an edge lit or side lit LED light.

If there is a sunlight readable display you"re not finding here, please talk to our support team, they might be able to find one that will fit your needs.

TRU-Vu High Bright Sunlight Readable Monitors enable users to see clear, sharp video images even in direct sunlight with a bright screen.  Our high brightness screens produce at least 1,000 nits brightness. Some go up to 2,500 nits of brightness.  This makes them far brighter than standard LCD monitors.  Specifically, consumer or commercial-grade monitors typically offer only 150 to 300 nits brightness.  High brightness displays and sunlight readable touch screens will ensure crystal-clear video images even in bright sunlight. The result is better performance and bold colors in other high ambient light conditions as well. They are also available with optical bonding as monitors or touch screen displays.

In outdoor or bright conditions, it is imperative to increase the brightness of a display to ensure crisp images.  The number of nits an LCD display emits is the main factor in determining the monitor’s perceived brightness. A monitor luminance of around 200-350 nits will work well indoors.  Most LCD displays and monitors fall in this range. However, 400-700 nits would be required for use in daylight conditions. Most importantly, a Sunlight readable display requires at least 1,000 nits or more for viewing in direct, bright sunlight . These high brightness displays are available with 16:9 aspect ratio or 4:3 aspect ratio screens.  All TRU-Vu Sunlight Readable monitors and high-brightness touch screens are TAA Compliant.

Some monitors feature a sheet of glass over the LCD panel to protect it from accidental or intentional damage. However, the glass also produces unwanted glare and reflections. Internal reflections in the air gap between the glass and the LCD panel diminish image quality even further. In order to combat this, monitors are optically bonded.

Optical bondingis the process of laminating protective glass or a touch screen panel to the LCD panel with an optical-grade resin.  This completely fills the air gap between the glass and LCD panel. It not only eliminates the internal reflections, but  also increases the contrast ratio. This makes the screen appear much brighter and more viewable in bright light conditions. Optical bonding  also eliminates internal moisture and condensation. Moreover, it will make the monitor more rugged and durable. Lastly, an Anti-Reflective coating is applied to the outside of the glass. Consequently, this will drastically reduce glare and surface reflections.

For installations in indirect sunlight, or reflected bright light, our Daylight Viewable displays will most likely suffice. These are also more cost-effective than Sunlight Readable monitors with 1,000 nits brightness. Daylight viewable monitors feature  LCD screens with 400 nits to 700 nits brightness.  The LCD panels also include optical bonding.

Daylight-viewable touchscreens with optical bonding are also significantly brighter than standard touch screens. Consequently, they produce far better image quality in bright conditions. Although they are not as bright as Sunlight Readable touch screens, daylight readable touch screens do offer the benefit of lower power consumption. This may be useful in portable or mobile applications. We currently offer over 60 monitors with optical bonding; all are TAA-Compliant.

Our outdoor high brightness Sunlight Readable LCD monitors feature waterproof stainless steel enclosures. These are ideal for factory wash-down environments.  Additionally, they are perfect for outside use in challenging weather.  Our panel mount enclosures are made from steel, stainless steel, or aluminum. This enables them to be flush-mounted. Outdoor LCD monitors with high brightness work in a wider range of temperatures. Consequently, this broadens the environments in which they may be used. Additionally, temperature ranges are very important to consider when using outdoors.  When we combine extreme operating temperatures with outdoor waterproof enclosures, we ensure your high brightness monitors will be able to function in even the harshest wet and hot environments. We will also modify or customize any model to meet your exact requirements.

In conclusion, we deploy TRU-Vu outdoor waterproof sunlight readable monitors and high brightness touch screens in a wide range of industries. For example, military, law enforcement, manufacturing plants benefit from high bright LCD displays. Amusement parks, sports stadiums, mass transit, and construction & heavy equipment also rely on high bright sunlight readable displays.  In addition, outdoor high brightness LCD monitors are demanded in pipeline inspection,  kiosks, marine,  oil & gas, drones, security applications. When it counts, you can rely on TRU-Vu Monitors to deliver the optimal weather resistant high bright LCD monitor solution for your specific needs.

Before answering the questions below, it would be helpful to provide a simple overview of how a TFT LCD works. Every monitor or touchscreen computer includes an LCD panel. The LCD panel is the component that you are viewing at this very moment. This panel includes a thin layer of TFT LCD pixels, where each pixel includes a red, blue, and green rectangle. You can actually see the individual pixels on a display if you place a drop of water on it. The drop will magnify the pixel area and reveal a pixel with a red, blue, and green rectangle. Each red, blue, and green rectangle is a small lens that can be adjusted to allow varying amounts of light to pass through. The colors you see on your screen are determined by how much light is passing through each adjustable red, green, and blue element of each pixel.

The light that you see does not come from the pixels themselves, but from the backlight behind the pixels, which is a series of carefully placed LEDs that emit white light that projects through the LCD pixels. You cannot see the individual backlight LEDs when you look at your monitor, because there is layer of light diffusing material between the LED backlight and the LCD pixel layer. The light diffusing material scatters the light from each individual backlight LED, so they do not show up as bright spots on your monitor.

To summarize, the three layers of an LCD panel are the TFT LCD pixel layer, the diffuser layer, and the LED backlight layer. Note that some LCDs have edge-lit backlighting, but there is no need to go into detail about this, as the same principles apply. That completes LCD panel course 101. Now, what makes a display sunlight readable?

There are two general ways to make an LCD brighter and therefore readable in sunlight. The first and simplest way is to increase the brightness of the backlight. LCD brightness is measured in Nits. Typical LCD panels have a screen brightness between 250 Nits to 450 Nits. LCD brightness of 800 Nits or higher is generally considered sunlight readable, but most sunlight readable displays are 1000 nits. Increasing the brightness of the LCD panel backlight is the most common method of making an LCD panel sunlight readable. Most of Teguar’s industrial panel PCs and touchscreen monitors are available with this type of high brightness LCD.

Another way to make an LCD sunlight readable is to change the diffuser material between the LED backlight and the LCD pixels to a “transflective” material. The transflective material is similar to reflective sunglasses or a one way window, where the shiny side is facing the LCD surface. When transflective material is used, the sunlight entering the LCD panel travels through the pixels, bounces off the transflective material, and is reflected back through the pixels to your eyes. In this case, the sunlight has much less of an impact on viewability than a traditional LCD panel, as the sunlight is reflecting back through the LCD pixels and contributing to the LCD brightness. One drawback of transflective diffuser LCDs is that they don’t allow for as much of the backlight to pass through the diffuser material, so in low light conditions the LCD does not appear as bright. Transflective diffuser LCDs are not as common as high brightness backlight LCDs.

Optical bonding improves viewability of touchscreen PCs in sunlight or other high-bright environments. In a touchscreen computer, the touchscreen sensor and the LCD panel are separate components. The touchscreen is mounted in front of the LCD surface and there is a small air gap between these two components. When sunlight passes through the touchscreen layer, some amount of the light is reflected between the LCD surface and the touchscreen; this reflection reduces LCD viewability.

Optical bonding is a process where a clear adhesive gel is placed between the LCD to the touchscreen. The gel hardens and bonds the touchscreen to the LCD to eliminate the air gap, improving contrast and clarity. Optical bonding is available on many of Teguar’s touchscreen computers and industrial monitors.

The brightness of a sunlight readable display may be overwhelming at night, when there is little or no ambient light. Most industrial computers with sunlight readable LCDs are available with an optional auto-dimming feature. With this feature, an ambient light sensor on the front bezel measures incoming light and adjusts the backlight brightness to match the current light conditions. This is typically a requirement for industrial touchscreen computers that are used in both sunlight and moonlight.

Sunlight also comes with a high amount of UV radiation that can damage the components used in touch screens. PCAP touch screens resist UV damage better than Resistive, but even a PCAP screen must be protected from too much UV exposure. Teguar computers are best suited for environments that provide some level of shade, such as a roof or overhang above the computer, or a structure that blocks the screen from direct exposure to the sun. Most outdoor computer manufactures, Teguar included, will offer a specialized shroud/hood that mounts directly to the unit to provide some level of shade.

Most of our products can handle a few hours of direct sun exposure per day, but full exposure to direct sunlight will cause damage to most touch screens in around 1 year. Contact a knowledgeable Teguar sales rep to discuss the details of your own environment and we can help determine the best solution.

Touchscreen computers in vehicles commonly require high brightness LCDs, because of the ambient sunlight coming through the windows. Sunlight readable LCDs are also used in many indoor applications surrounded by windows, such as air traffic control centers, railroad cars, marine vessels, agriculture machinery, and public kiosks.

Sunlight readable TFT displays feature high brightness LCD backlights, making them an excellent option for bright ambient light or direct sunlight environments. Our sunlight readable TFT displays are available with or without touchscreen features and come with different formats and display modes to fit any application.

It is a complex recipe that requires the right balance of key ingredients that include enhanced backlight, optimized internal film stack, front coverglass with correct index matched coatings all integrated into the ideal host LCD panel for the application.

The SSD2735-A is a 27.3" square LCD monitor with high-brightness for sunlight readability. The display is LED backlit to a brightness of 1000 Nits and has a resolution of 945 x 1080, making the screen near square with an aspect ratio of 8:9. This specific ratio is useful for applications in digital signage, public transportation, exhibition space, vending machines and industrial applications.

Sunlight readable LCDs are designed to work in direct sunlight or strong light conditions and are also referred to as daylight visible LCDs or outdoor LCDs. Different techniques can be used to make LCDs readable under conditions of strong light exposure. It does this by increasing the contrast between the object and the background. For human vision, a contrast ratio of 2:1 is the minimum, 5:1 is acceptable and 10:1 is optimal.

This method is achieved by adjusting the LCD backlight brightness and the contrast of light. The following are suggestions for selecting the brightness of TFT LCD in different light environments.

The semi-transmissive TFT LCD display has a built-in rear polarizer of translucent material, which is used for its own illumination by reflecting light from the surrounding part, and the stronger the light, the brighter the TFT LCD.

Since semi-transmissive TFT LCD has both transmittance and reflectance characteristics, it works well in both outdoor and indoor environments. In addition, it is very energy efficient and especially suitable for battery-powered devices.

To further improve the readability of TFT LCD under direct light, anti-reflection and anti-glare can be used for processing, and reflective film can reduce the reflected light into the eyes of the observer.

Optical bonding is the process of filling the air gap between the TFT LCD and the top surface of the display with an optical grade adhesive. Optical bonding reduces the refraction of light (from the LCD backlight and from outside), thereby improving the readability of the TFT display. In addition to the optical benefits, it also serves to improve the durability and touch accuracy of the touch screen and prevents fogging and condensation.

While high brightness LCD displays generate more heat and consume more energy than traditional LCD displays, LED lights to minimize power consumption, our sunlight readable LCD multiple touch screen options, including resistive and capacitive screens. Sunlight readable touch screens are specifically designed for indoor needs and outdoor applications, and are now successfully used in vending kiosks, electric vehicle charging stations, and environmental monitoring.

Sun Vision Display panels are100% reflective, meaning they have no backlight whatsoever. This makes them an excellent computer monitor solution for people looking to reduce blue light exposure or other common issues reported by people withcomputer-related vision syndromes. It also makes them an incredible solution for advertising in sunny places, where it can be difficult to view other display technologies - all without racking up hefty energy costs.

LCDs used in outdoor situations have many concerns to deal with in addition to any that they might normally encounter during indoor use. Initially some concerns are weather related such as moisture in the air or extreme temperatures. Another concern that is often not understood or just not known about at all is sunlight damage.

Liquid crystal displays use organic components that are susceptible to UV (<400 nm) and IR (>750 nm). These bandwidths of radiation have an observable impact on the organic components in LCDs. Extended exposure has been known to cause a color shift and a washed out look to images displayed with the LCD.

Over time the UV and IR radiation degrade the organic components causing them to fail to function properly. The amount of time it takes can vary depending on brand and model as well as specific weather conditions the display has been exposed to. For instance some atmospheric disturbances can reduce the amount of Ultraviolet that is transmitted to the display.

In any case it is important to protect your display from the elements, especially if it is going to be exposed to harsh environments not intended by the manufacturer. One way to do this would be to utilize a Hot Mirror with a UV blocker. This will significantly reduce the amount of IR radiation between 750 nm and 1200 nm, as well as the UV radiation below 400 nm. If the LCD is going to be used outdoors for extended periods then an extended hot mirror may be necessary, which extends the bandwidth protection out to 1600 nm and will help reduce some of the longer wavelength IR damage.

Another concern with liquid crystal displays are their susceptibility to overheating due to excess IR radiation. The LCD is intended to operate within a certain range of temperatures according to the manufacturer’s instructions and outdoor use can lead to higher than normal temperatures. The display being exposed to excessive heat can cause the crystal to become isotropic and fail to perform properly. A hot mirror can help alleviate these concerns as well by reducing the amount of infrared radiation that heats the display.

Sunlight readable LCD monitors are designed for outdoor industrial display applications. It features a transflective LCD module that improves the display contrast through the high brightness backlight source and illuminance sensor that lets LCD readable display function in over a wide range of illuminance levels. When exposed under the sun, the sunlight-readable display adjusts to the brightness of outdoor conditions and utilizes the light beams to give off illumination. The display reflects against the light passing through the screen and becomes constant with the contrast of the beams. The transflective technology allows the display to become viewable under the brightest luminance regardless of the original brightness of the LCD. Sunlight readable displays can be utilized in all conditions including under direct sunlight and provides better contrast for both outdoor and indoor environments. In the dark, the backlight is turned on to display the best possible image, allowing the display to be useful in both high and low lighting.
