Many users have asked about ultra high brightness display screens, and the editor has previously explained the relevant knowledge of high brightness display screens to everyone. Today, we will continue to introduce high brightness display screens, and the theme we will introduce is some differences between ultra high brightness display screens and ordinary display screens. This will make it easier for everyone to understand high brightness display screens:
1. High brightness
Undoubtedly, high brightness displays have higher brightness than regular displays. The brightness of a regular LCD screen is generally only 250-300cd/㎡, while the brightness of a bright LCD screen can reach over 700cd/㎡.
2. Longer service life
The lifespan of the backlight source for ordinary LCD screens is 10000 to 30000 hours, while the lifespan of the backlight source for high brightness displays can reach over 60000 to 100000 hours. This ensures the consistency of brightness, contrast, and chromaticity for each LCD screen used in high brightness displays after long-term use, and ensures that the lifespan of the display screen is not less than 60000 hours.
3. Better reliability and performance
Ordinary display screens do not support continuous use day and night, while high brightness LCD displays support continuous use for 7x24 hours.
4. High contrast
High brightness display screens have a contrast ratio of 1200:1, or even up to 10000:1, which is more than twice that of traditional regular displays and three times that of typical rear projection screens.
5. Uniform brightness, stable and non flickering image
Due to the fact that LCD maintains the same color and brightness at each point after receiving the signal, unlike CRT which requires constantly refreshing pixel points. Therefore, the LCD has uniform brightness, high image quality, and absolutely no flicker.
