Problems solved by technology

Thus making the replacement of the light source 118 quite time consuming
Moreover, in the process of disassembly and assembly, it may also cause damage or contamination of other components
[0008] Moreover, when the product composed of the liquid crystal display 100 module needs to replace the light source at the client, the liquid crystal display 100 module must be removed from the client product first, and then the liquid crystal display 100 module must be disassembled to replace the light source , the same is not only quite time-consuming, but also has the problem of causing damage or contamination to other components during the disassembly and assembly process

Abstract

A back light module and LCD is disclosed. Said back light module is composed of a light guide plate with light incidence surface, light exit surface and light diffusing surface, a light source arranged by light incidence surface, and a frame with a drawing hole on one side of carrying said light guide plate and light source.

Description

technical field [0001] The present invention relates to a backlight module (Back Light Module) and a liquid crystal display (Liquid Crystal Display, LCD), and in particular to a backlight module in which the light source can be replaced without disassembling the backlight module. group and LCD display. Background technique [0002] In order to adapt to the modern life style, the volume of video or image devices is becoming thinner and thinner day by day. Although the traditional cathode ray display (CRT) still has its advantages, due to the structure of the internal electronic cavity, the display is bulky and takes up space, and there are still problems such as radiation damage to the eyes when displaying. Therefore, flat panel displays (Flat Panel Displays), such as liquid crystal displays (LCDs), organic light-emitting displays (OLEDs), or plasma displays (Plasma Display Panels, PDPs), which are developed in conjunction with optoelectronic technology and semiconductor man...
