In the outdoor strong light environment, to improve the visibility of the LCD back cover (here should refer to the LCD display, because the LCD back cover itself does not directly affect the visibility), the key is to enhance the brightness and contrast of the display, while reducing the reflected light to ensure that the screen content is still clear in the strong light. Here are some effective tips:
High-lighted LED backlight:
Outdoor high-brightness LCD screens are usually brighter than 600 nits, and the ideal sunlight readable brightness reaches 800 to 1,000 nits, or even higher.
By increasing the LED backlight brightness of the LCD module, it is equal to or even higher than the natural light brightness of the outdoor, so as to achieve high definition outdoor display.
Using semi-reflective semi-transparent technology:
The semi-inverse semi-transparent LCD screen combines two display technologies, such as reflection and transmission, which can be seen in outdoor sunlight like reflective LCD, and can be normally displayed like transmitted LCD in indoor environment.
In outdoor lighting conditions, the semi-reflective semi-transparent screen converts ambient light into the backlight of the LCD screen through the reflection layer, increasing the brightness and contrast of the screen.
Application of AR anti-reflection film:
The anti-reflection (AR) film attached to the surface of the LCD display can effectively reduce the reflected light between the air and the glass surface.
AR film can also play a role in anti-glare, reducing glare and diffusing reflected light on the display, improving visibility.
Using optical bonding technology:
Optical bonding technology uses an optically grade adhesive to fill the air gap between the LCD display and the touch screen (if present).
Since the refractive index of the transparent optical adhesive is almost equal to that of the screen film, the reflection between different media can be eliminated and the readability of the screen can be improved.
Optical bonding also enhances the durability and touch accuracy of the touch screen, preventing fog and condensation.
Select the right display type:
For outdoor applications, high-brightness LCD displays or displays using semi-reflective and semi-transparent technology are preferred.
Consider the display's contrast, viewing Angle, color saturation and other parameters to meet the visual needs of outdoor environments.
Consider environmental factors:
The outdoor environment is complex and changeable, requiring the display screen to have a wide temperature working range, high stability and long life.
Choose display products that can adapt to the harsh outdoor temperature environment and sunlight exposure.
TCL Huxing Outdoor bright LCD custom solution: TCL Huxing launched UHD outdoor bright LCD custom solution with module brightness of more than 4000 nits, using TSS pixel design to achieve high penetration specifications, support ultra-high brightness, and can present better display effect under outdoor bright light.
Sai Sai Da outdoor bright LCD screen: Sai Sai Da provides LCD screen products brightness can be customized, up to 1500 nits, to meet the outdoor multi-scene application needs.
To improve the visibility of LCD display in outdoor strong light environment, it is necessary to improve brightness, reduce reflected light and optimize display design. The readability and display effect of LCD display under outdoor bright light can be effectively improved by using high-light LED backlight, semi-reflective and semi-transparent technology, AR anti-reflective film and optical bonding technology. At the same time, it is also crucial to choose a display product suitable for the outdoor environment.
