Description

technical field

[0001] The invention relates to an optical thin sheet used in a backlight assembly assembled in a liquid crystal display device, which has high uniformity optical properties, distributes light evenly, and achieves good optical effects. Background technique

[0002] The liquid crystal panel itself does not emit light, so the backlight as a source of brightness is an important component of the LCD display function, and is very important for improving the brightness of the liquid crystal display.

[0003] In addition, LCD products have been expanded from notebook computers or LCD screens to LCD TVs. The key points to consider are sufficient display brightness, wide viewing angle, sharp image contrast and standard service life. In order to meet the above requirements, "Direct Type Backlight" (Direct Type Backlight) has become the mainstream technology for matching large LCD TVs. figure 1 It is a schematic diagram of a conventional direct-lit backlight module.
