Problems solved by technology

When assembling the backlight module, the rubber pads must be inserted one by one into the lamp tube fixing seat, so the use of rubber pads increases, which will not only take longer man-hours to assemble the backlight module, but also increase the assembly process. Complexity, resulting in increased cost and decreased yield
In addition, since the rubber pad is plugged into the space of the lamp tube holder and thus positioned, the positioning between these two independent components will inevitably produce fit tolerances, which will reduce the accuracy of the overall size
Furthermore, since the rubber pad and the lamp tube fixing seat are divided into two independent parts, after the rubber pad is positioned in the space of the lamp tube fixing seat, there is still a gap between the two parts, which will affect the entire combination Heat dissipation and shock resistance of the device

Abstract

The invention discloses a backlight module and a liquid crystal display (LCD) applying the backlight module. The backlight module at least comprises a backing plate, a plurality of lighting tubes and fixing devices which are respectively arranged at the opposite two sides of the backing plate, wherein, each of the fixing devices of the lighting tubes at least comprises a shell and at least one holding part fixed in the shell; two ends of the lighting tube are respectively fixed in the holding part of the fixing device of the lighting tube.

Description

technical field [0001] The invention relates to a backlight element, and in particular to a backlight module and a liquid crystal display using the same. Background technique [0002] Liquid crystal display is currently the fastest growing product in the optoelectronic industry. With the mass production of liquid crystal displays, various manufacturers have spared no effort in pursuit of low-cost, high-functionality and easy-to-assemble display devices. [0003] Generally speaking, a liquid crystal display roughly includes a display panel and a backlight module, wherein the backlight module is disposed on the back of the display panel to provide a backlight source for the display panel. A typical backlight module mainly includes a backplane, a lamp tube, a lamp holder (Lamp Holder) and a rubber pad (Rubber). And the rubber pad must be used as a structural buffer, so the rubber pad is used for inserting and fixing the lamp tube, and the lamp tube fixing seat can be used for...
