Abstract

The invention provides a backlight module. The backlight module comprises a light source module, a plurality of light guide bars and a plurality of scattering parts, wherein the light source module isused for emitting a plurality of dot lights; each light guide bar contains one incident side and an outgoing side, the incident side is aligned with the corresponding dot light in the light source module so as to convert the dot light into linear light; and the scattering parts are arranged on the outgoing side of the light guide bars and used for making the light guided out from the light guidebars irradiate to the outside, wherein the plurality of light guide bars are arranged in parallel at intervals along a first direction.

Description

technical field [0001] The disclosure relates to a backlight module, in particular to a backlight module for a display. Background technique [0002] In recent years, due to the advantages of low power consumption, high brightness and good color saturation, liquid crystal displays (LCDs) have been widely used in various modern electronic products, such as personal computers, digital cameras, smart phones, etc. Mobile phones, tablet computers, LCD TVs, etc. A liquid crystal display is assembled from multiple components, and the backlight module is a key component of the liquid crystal display, which affects the overall power consumption, brightness and color saturation of the liquid crystal display. [0003] At present, the LCD backlight module mainly adopts the side-type or direct-type design to reduce the number of light-emitting diodes (light-emitting diodes, referred to as LEDs) used, thereby achieving energy-saving and cost-saving effects. However, no matter what kind ...
