Problems solved by technology

[0004] However, the backplane uses a relatively large amount of metal materials, which makes the backlight module relatively heavy, and the backplane raw material is only one or two specific types. The cost of the backplane is subject to large fluctuations in raw material prices, which is not conducive to cost control.

Embodiment Construction

[0025] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0026] see Figure 2 to Figure 4 The present invention provides a side-entry backlight module, comprising: a backplane 2, a backlight 4 disposed in the backplane 2, and a light guide plate 6 disposed in the backplane 2, the backplane 2 includes a body 22 and The bracket 24 is connected to the body 22 , the body 22 is made of plastic material, the bracket 24 is made of metal material, and the backlight 4 is installed on the bracket 24 . Preferably, the body 22 is made of plastic material with high reflectivity, and the bracket 24 is made of metal material with high thermal conductivity. The plastic material can be selected from thermoplastic (Thermoplastic), such as PC (Polycarbonate, polycarbonate resin), PA (Polyamide, polyamide), etc. In th...

Abstract

The invention provides an edge type backlight module, which includes a back panel, a backlight source arranged in the back panel and a light guide plate arranged in the back panel, wherein the back panel includes a main body and a bracket connected with the main body, the main body is made of plastic materials, the bracket is made of metal materials, and the backlight source is mounted on the bracket. Though adopting the back panel formed by combining the plastic main body and the metal bracket, the weight of the edge type backlight module is light; as more plastic materials can be selected, the defects of simplex raw material and significant price fluctuation in the existing back panel are further overcome, and the production cost is efficiently lowered; moreover, the main body is directly provided with a reflection surface, so that the use of a reflective sheet is avoided, the installation of the light guide plate is facilitated, and the production cost is further lowered.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a side-entry backlight module. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of the liquid crystal molecules is controlled by electrifying or not, and the light of the backlight module Refracted out to produce a picture. Since the liquid crystal display panel itself does not emit light, the backlight provided by the backlight module is ...
