Abstract

The invention discloses a backlight module for combining with a display panel. The backlight module has a back plate and a diffuser plate. A plurality of luminous strips are arranged on the back plate, and each of the luminous strips is provided with at least one light emitting module. , wherein each of the light-emitting modules has an LED forward light source and at least one pair of LED non-direct light sources, and the pair of LED non-direct light sources are arranged on the side of the LED forward light source, and the LED forward The light emitted by the type light source is combined with the light emitted by each of the LED non-direct light sources to form a diffused light shape on the diffuser plate, and the diffused light shape formed by each of the light-emitting modules is mutually formed on the diffuser plate splice distribution. Therefore, through the backlight module of the present invention, the number of light strips can be reduced, so as to reduce the weight, volume and cost of the whole backlight module and the liquid crystal display, and make up for the problem of uneven brightness and darkness of the existing backlight module.

Description

Technical field [0001] The present invention is related to the backlight module, and in particular refers to a backlight module that can reduce the number of light-emitting bars and light-emitting diodes, and overcome the problem of uneven brightness of the existing backlight module, so as to display a uniform backlight source. Background technique [0002] Liquid crystal display is a passive display device. It does not have the function of automatically emitting light. A light source must be provided to provide the display light source required by the display panel. Therefore, whether the backlight module in the liquid crystal display can emit a light source of sufficient brightness to make the display panel The uniform brightness on the LCD will affect the image quality of the LCD. [0003] Generally speaking, the backlight module can be divided into (Frontlight) and backlight type (Backlight), and the backlight module can be further divided into an edge type structure, a hollow ...
