Backlight module set

Abstract

The invention supplies a backlight module includes a light guiding board, at least a light resource. A light intake surface, a light emitting surface and a bottom are included into the light guiding board. The backlit module at least includes a cylindrical mirror between light resource and light guiding board.

Description

【Technical field】 [0001] The invention relates to a backlight module, in particular to a side-mounted backlight module. 【Background technique】 [0002] Since the liquid crystal display is a non-luminous display device, a backlight module is required to produce a display function. The performance of the backlight module often directly affects the image quality of the display. Therefore, the backlight module becomes the most important component in the liquid crystal display. The so-called side-mounted backlight module means that the light source is arranged on one side of the light guide plate, and the light beam enters the light guide plate from the side and continuously propagates forward in the light guide plate. Displays with side-mounted backlight modules are widely used in fields such as notebook computers, vehicle displays, and mobile communications due to their small size and light weight. [0003] The light source of the backlight module can be a cold cathode fluore...

Problems solved by technology

This structure has a certain effect on eliminating dark bands, but since the reflector 31 is arc-shaped, the LED light source 33 will block part of the light reflected back from the reflector 31, which is easy to form on the light guide plate 35 behind the multiple LED light sources 33. A small shadow area, thereby affecting the uniformity of light emission of the backlight module 30 and reducing the utilization rate of light energy
