High-brightness LCD screen is a LCD screen with high brightness and contrast, which can provide better viewing vision under strong ambient light. Ordinary LCD screens are generally not easy to see images in the sun.

A, highlight the difference between LCD screen and ordinary LCD screen

1, High brightness of advertising display machine screen

Compared with TV and PC LCD screens, high-brightness LCD screens have higher brightness. The brightness of TV or PC LCD screen is generally only 250~300cd/㎡, while the brightness of high-brightness LCD screen can reach more than 700cd/㎡.

2, High contrast of advertising display machine screen

The bright LCD screen has a contrast ratio of 1200: 1, even up to 10000: 1, which is more than twice as high as the traditional PC or TV LCD screen and three times as high as the general rear projection screen.

3. Better reliability of advertising display machine screen

Ordinary LCD screen is designed for TV and PC monitors, and it does not support continuous use day and night. Highlighted LCD screen supports continuous use in 7x24 hours.

4, The brightness is uniform, and the image is stable and does not flicker.

Because every point of LCD always keeps that color and brightness after receiving the signal, unlike CRT, it is not necessary to constantly refresh the pixel points. Therefore, LCD has uniform brightness, high image quality and absolutely no flicker.

5, Longer service life of advertising display machine screen

The service life of LCD backlight used by ordinary NB, PC and TV is 10,000 to 30,000 hours, while the service life of DID LCD backlight can reach more than 60,000 to 100,000 hours, which ensures the consistency of brightness, contrast and chromaticity of each LCD used for splicing display screens after long-term use, and ensures that the service life of the display screen is not less than 60,000 hours.

B, LCD display and LED display.

In the high-brightness LCD industry, consumers often encounter merchants saying that LCD screen is changed to high-brightness and LED screen is changed to high-brightness. What is easily mistaken by consumers is the LED dot matrix display screen on the market at present. The former is the LCD screen, while the latter is the light-emitting diode. The former is a display device composed of liquid crystal glass and backlight, while the latter is directly displayed by light-emitting diode. It should be noted that the LCD screen /LED screen mentioned in the high-brightness LCD screen industry is actually derived from the backlight naming method. The LCD screen (CCFL backlight) and LED screen (WLED backlight) are actually changed to WLED backlight, and the LED screen is changed to brighten the original WLED backlight LCD screen. Of course, the high-brightness screen is not only to change the backlight, but also to consult the corresponding manufacturer of high-brightness LCD screen-Rui for further technical problems.

The highlight LCD screen and ordinary LCD screen are introduced here. For those who don't know whether to choose highlight LCD screen or ordinary LCD screen when purchasing, always consult official website customer service. Generally, highlight LCD screens are mostly used outdoors.
