Description

A backlight module for ultra-wide-angle LED liquid crystal display

Technical Field

The utility model belongs to the field of backlight modules, and in particular relates to a backlight module of an ultra-wide-angle LED liquid crystal display.

Background Art

Traditional LCD displays may experience reduced brightness or color distortion when viewed from the side or up and down angles. Ultra-wide-angle technology allows viewers to maintain high visual performance over a larger range, and maintain a relatively uniform and accurate display no matter from which angle. In LCD displays, the backlight module is a component used to illuminate the LCD panel. The liquid crystal itself cannot emit light, so the backlight module is required to provide a light source. The backlight module usually uses LED as a light source, which distributes light evenly across the entire LCD panel through different optical components (such as reflectors, light guides, diffractors, etc.) to ensure the brightness and uniformity of the display. However, the current backlight module frame is usually difficult to quickly install in the ultra-wide-angle LED LCD display housing, and the heat dissipation structure on the frame has insufficient heat dissipation effect on the backlight module, affecting the service life of the backlight module.
