Problems solved by technology

However, this way of using screws to lock the control circuit board to the frame, although the liquid crystal display has the advantage of being convenient for rework, is not enough when assembling the control circuit board to the frame or disassembling the control circuit board from the frame. time consuming
In addition, the thickness of the liquid crystal display cannot be effectively reduced

Abstract

The invention discloses a display device and a backlight module. The display device comprises a liquid crystal panel, a backlight module and a control circuit board. The backlight module is arranged under the liquid crystal panel, wherein the backlight module comprises a light source and a frame. The frame is provided with a limiting structure; and the limiting structure is provided with an extending part and a limiting part, wherein the extending part is connected with the limiting part. The control circuit board is arranged under the backlight module, wherein at least one part of the limiting part covers the control circuit board in order that the control circuit board is fixed on the backlight module.

Description

technical field [0001] The present invention relates to a display device, and in particular to a display device that is easy to rework. Background technique [0002] Since the invention of the first black-and-white television with a cathode ray tube (Cathode Ray Tube, CRT) working mode, display technology has been evolving at a rapid pace. Due to the disadvantages of large size, heavy weight, high radiation and poor image quality of this kind of display working in cathode ray tube mode, new technologies are constantly being developed for flat panel display technology. Among these flat panel display technologies, the liquid crystal display (Liquid Crystal Display, LCD) technology, which has the advantages of thinness, lightness, power saving, no radiation, full color, and portability, is the most sophisticated and popular. For example, mobile phones, language translators, digital cameras, digital video cameras, personal digital assistants (personal digital assistants, PDAs),...
