Illuminance is defined as the intensity of light (luminosity) per unit projected area on any surface in a given direction, as viewed from the same direction. In addition, the uniformity of brightness is also very important.
The uniformity of brightness is closely related to the number and configuration of backlight sources and reflectors.
High quality high brightness LCD displays have uniform brightness, soft and non glaring images, and no obvious dark areas.

The difference between high brightness LCD advertising machine screen LCD screen and high brightness LCD screen LED screen: In the high brightness LCD display industry, consumers often encounter businesses saying that LCD screen should be changed to high brightness and LED screen should be changed to high brightness.
