A kind of assembly method of backlight module, display device and backlight module

Abstract

The invention relates to the technical field of display devices, and discloses a backlight module, a display device and an assembly method of the backlight module. The backlight module includes a backboard, and the backboard includes a drawer-type assembly part, and the optical assembly is inserted into the assembly part, and several positioning assemblies are arranged in the assembly part, and the positioning assembly positions the optical assembly. The backlight module sets a drawer-type assembly part on the backplane, so that the optical components can be installed inside the assembly part in the form of insertion, and then the optical components are positioned by the positioning component to realize the assembly and fixation of the optical components and the backplane . Compared with the existing technology, the middle frame and other parts need to be provided, which reduces the number of assembly parts, reduces the assembly cost, simplifies the assembly relationship, improves the assembly efficiency, and effectively reduces the thickness of the backlight module; In the display device of the backlight module, the display panel can be assembled and installed with the backplane through the connector, and the assembly relationship is simple and efficient.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a backlight module, a display device and an assembly method for the backlight module. Background technique [0002] With the development of TV display technology, people pay more and more attention to product appearance while paying attention to product quality, and constantly require display devices to develop in a thinner and narrower direction. Therefore, floating screens have become a popular shape that is widely loved. [0003] For the direct-lit backlight module, the existing assembly method is to first fix the light bar on the back panel, then stack optical components such as reflectors, diffusers, and diaphragms in sequence, and finally assemble them through the middle frame. In the above assembly method, connectors are required between each optical component, which will lead to many types of parts, complex assembly relationship, high assembly cost and low...

AI Technical Summary

Problems solved by technology

In the above assembly method, connectors are required between each optical component, which will lead to many types of parts, complex assembly relationship, high assembly cost and low efficiency, which limits the shape and thickness of the backplane, and the backplane must be made into an open shape To ensure that the optical components can be placed in sequence from top to bottom, this will cause the suspension screen to be unable to be assembled normally and effectively

[0004] Therefore, it is urgent to propose a method for assembling a backlight module, a display device, and a backlight module to solve problems in the prior art that there are many assembly parts, high assembly costs, inability to install a floating screen, and a large thickness of the backlight module. technical issues
