Abstract

The invention relates to a back light module and a manufacture method thereof. The manufacture method of the back light module comprises the following steps: providing a back plate which is provided with a first side edge, a second side edge, a third side edge and a fourth side edge, wherein the first side edge is opposite to the second side edge and the third side edge is opposite to the fourth side edge; performing injection molding on a first frame on the back plate; inserting a light source and an optical membrane into the first frame; and enclosing the first frame by the a second frame. The invention can effectively reduce the complexity of the back light module and the assembly working time, solve a matching problem which may occur in assembly and also ensure that the reprocessing of the back light module is more convenient.

Description

technical field [0001] The present invention relates to a backlight module and its manufacturing method, in particular to a backlight module with more convenient assembly and rework and its manufacturing method. Background technique [0002] Flat panel displays have been widely used in various electronic devices. Taking liquid crystal display as an example, it is mainly composed of a liquid crystal panel and a backlight module. The liquid crystal layer is composed, and the backlight module is used to provide the surface light source required by the liquid crystal panel, so that the liquid crystal display can achieve the display effect. [0003] The backlight modules of liquid crystal displays are generally divided into direct type and side type. Taking the side-entry type as an example, the current assembly method of the side-entry backlight module mainly includes the following steps: first assemble the reflector, reflector, light guide plate, etc. on the backplane, then as...
