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.

When display devices are brought outside, oftentimes they face the brightness of sunlight or any other form of high ambient light sources reflecting off of and overwhelming the LED backlight’s image.

With the growth of the LCD panel industry as a whole, it has become more important than ever to prevent the sun’s wash out of displays used outdoors, such as automobile displays, digital signage, and public kiosks. Hence, the sunlight readable display was invented.

One solution would be to increase the luminance of the TFT LCD monitor’s LED backlight to overpower the bright sunlight and eliminate glare. On average, TFT LCD screens have a brightness of about 250 to 450 Nits, but when this is increased to about 800 to 1000 (1000 is the most common) Nits, the device becomes a high bright LCDand a sunlight readable display.

Doing this is an affordable option for enhancement of image quality in the outdoors, including features like contrast ratio and viewing angle, in a common use setting like with phones.

Since many of today’s TFT LCD display devices have shifted to touchscreens, the touch panels on the surface of LCD screens already block a small percentage of backlighting, decreasing the surface brightness and making it so that the sunlight can even more easily wash out the display. Resistive touch panels use two transparent layers above the glass substrate, but the transparent layers can still block up to 5% of the light.

In order to optimize the high brightness of the backlight, a different type of touchscreen can be used: the capacitive touchscreen. Though it is more expensive than the resistive touch screen, this technology is more ideal for sunlight readable displays than the resistive due to its usage of a thinner film or even in-cell technologies rather than two layers above the glass of the display, and therefore, light can pass more efficiently.

However, with this method comes a list of potential problems. Firstly, high brightness displays result in much greater power consumption and shorter battery life. In order to shed more light, more power will be needed which can also consequently result in device overheating which can also shorten battery life. If the backlight’s power is increased, the LED’s half-life may also be reduced.

While in bright exterior light settings, these devices reduce eye strain as the user attempts to view the image on screen, the brightness of the display itself can also cause eye strain, seen as the brightness may overwhelm your eyes. Many devices allow the user to adjust brightness, so this concern is oftentimes not too severe.

A recent technology falling into the sunlight readable display category is the transflective TFT LCD, coming from a combination of the word transmissive and reflective. By using a transflective polarizer, a significant percentage of sunlight is reflected away from the screen to aid in the reduction of wash out. This optical layer is known as the transflector.

In transflective TFT LCDs, sunlight can reflect off the display but can also pass through the TFT cell layer and be reflected back out off a somewhat transparent rear reflector in front of the backlight, illuminating the display without as much demand and power usage from the transmissive nature of the backlight. This addresses both the issues of wash out and the disadvantages of high brightness TFT LCDs in high ambient light environments. Because of its transmissive and reflective modes, this type of device is very useful for devices that will be used outdoors but also indoors.

While it does greatly reduce power consumption, transflective LCDs are much more expensive than high brightness LCDs. In recent years, the cost has decreased, but transflective LCDs continue to be more costly.

In addition to adjustments to the internal mechanics of LCDs, it is possible to make devices more sunlight-readable using surface treatments. The most common are anti-reflective (A/R) films/coatings and anti-glare processing.

Anti-reflective focuses on depositing multiple transparent thin film layers. With the thicknesses, structures, and properties of each individual layer composing the film, reflecting light wavelengths are changed, and thus less light is reflected.

When anti-glare is used, reflected light is fragmented. Using a rough surface as opposed to a smooth one, anti-glare treatments can reduce the reflection’s disruption of the actual image of the display.

Often paired with other methods of creating sunlight readable displays is optical bonding. By gluing the glass of a display to the TFT LCD cells beneath it, optical bonding eliminates the air gap that traditional LCD displays have in them using an optical grade adhesive.

This adhesive reduces the amount of reflection between the glass and LCD cell as well as the reflection of external ambient light. Doing this helps provide a clearer image with an increased contrast ratio, or the difference in the light intensity of the brightest white pixel color and darkest black pixel color.

With this contrast ratio improvement, optical bonding addresses the root issue with unreadable outdoor displays: the contrast. Though an increase in brightness can improve contrast, by fixing the contrast itself, LCD display images in outdoor environments will not be as washed out and will require less power consumption.

Besides the visual display advantages that optical bonding provides, this adhesive improves the display in many other ways. The first being durability, optical bonding eliminates the air gap within the device and replaces it with a hardened adhesive that can act as a shock absorber.

Touch screens with optical bonding gain, accuracy in where the point of contact is between the touch and screen. What is known as parallax, the refraction angle of light, can make it seem that the point of contact and the actual point on the display are different. When the adhesive is used, this refraction is minimized, if not reduced.

The optical bonding adhesive’s elimination of the air gap also protects the LCD from moisture/fogging and dust, as there is no space for impurities to penetrate and remain under the glass layer. This especially helps with maintaining the state of LCDs in transport, storage, and humid environments.

Compiling the various methods of improving LCD screens for sunlight readability, these devices can be optimized in high ambient light settings. An anti-glare coating is applied to the surface of the glass and anti-reflective coatings are applied to both the front and back. The transflector is also used in front of the backlight. These features can result in 1000 Nit or more display lighting, without the excessive power consumption and heat production through a high brightness backlight, consequently allowing for a longer lasting and better performing LCD

Unfortunately, the process of building a reflector inside TFT LCD is complicated and transflective TFT LCD is normally several times higher cost compared with normal transmissive TFT LCD.

To further improve and enhance the qualities of the LCD, LED and cold cathode fluorescent lamp (CCFL) backlights are used. Both these create bright displays, but the LED specifically can do so without as much power consumption and heat generation as compared to the CCFL option. Optical bonding is also applied in order to improve display contrast, leading to a more efficient and better quality sunlight readable display.

NMLCD-05TSFis a transflective type TFT-LCD module which is sunlight readable. This module is composed of LCD panel, driver IC, and LED backlight. The resolution is 480×480.

Visible in sunlight-readable display TFT LCD Module does not fully recover its color in sunlight, but it can still be seen clearly, with only a slight change in color.TFT is divided into semi-penetrating and reflective types. In the sunlight, the semi-transparent brightness will have a certain degree of reduction, the color deviation will also have a certain degree of change, which is generally acceptable.

The outdoor sunlight-readable display effect of reflective TFT is better than that of semi-penetrating TFT because the former is displayed by the brightness of a complete backrest light plate, while reflective TFT is similar to the mirror, which can improve the display brightness by borrowing the ambient brightness. Therefore, the higher the ambient brightness is, the higher the screen brightness will be.

This paper makes a comprehensive comparison between high brightness TFT LCD and horizontal TFT LCD from the aspects of technical parameters, display performance, and cost evaluation. After reading this article, you will have a deep understanding of sun-readable TFT and how to select sun-readable TFT LCD to select the most suitable commutating TFT LCD or high-brightness TFT LCD for your outdoor display.

As can be seen from the parameters, STONE STVA035WT-01 is a sunlight readable TFT LCD module with a brightness of 1000 CD /m2. The color TFT LCD has a 320×240 resolution, supports RS232/USB ports, has a 3.5-inch diagonal size, and has resistive and capacitive touch screens. The TFT model has a built-in Cortex M4 driver chip.

The 3.5-inch daylight readable TFT LCD has a logical power supply voltage (V) ranging from 6V to 12v, with a maximum of 40V.

It can work at -20℃~ +70℃, and the storage temperature is -30℃~ +80℃.STONE daylight readable TFT LCD is an ideal choice for outdoor industrial measuring instruments, testing equipment, measuring tools, outdoor display, and other industrial electronic equipment.

Because of the requirement of the display that works in a bright environment and direct sunlight, the requirement of a TFT LCD screen is higher and higher.

Horizontal reflection TFT displays have a layer of reflectors in front of the backlight. Incident light bounces off the reflective layer and is used to illuminate the TFT display. Therefore, the TFT LCD module has two characteristics of “transmission” and “reflection”.

1. The reflective TFT display has good readability under bright ambient light and direct sunlight. Transmission TFT LCD displays can only work under backlight, while transverse reflection TFT displays are characterized by a reflector on the color filter of the TFT unit, so the incoming ambient light is reflected in the TFT reflective layer and then illuminates the display. Thus, the readability of the content is perfect in very bright sunlight, even without backlighting.

2. Compared with the traditional “transmission only” display, another advantage of the cross-flow TFT LCD display module is power saving. Cross-flow TFT LCD displays combine the advantages of both transmission and cross-flow displays so that TFT displays are fully readable under almost any ambient light condition. In addition, they are highly energy-efficient and are ideal for battery-powered devices and mobile applications. In a bright environment, customers who use a retro-streamlined TFT-LCD can save power by reducing or turning off the backlight of the display, due to the dominance of “reflection” mode.

The horizontal TFT LCD modules of brands such as Winstar Raystar have higher horizontal flow. If they only use the semi-transparent reflective polarimeter back delivery TFT LCD with a reflectance of only 2%, then it is not a true semi-transparent reflective TFT LCD.

The STONE sunlight-readable display module adopts the “transmission” mode, which improves the TFT-LCD panel structure, expands the color reproduction range under the “transmission” mode, and realizes a new TFT-LCD module, which gives full play to the advantages of the transmitted TFT LCD module in a vivid display of color.
