Problems solved by technology

[0004] However, using welding to connect the U-shaped lamp tube 110 and the wiring 120 not only requires more assembly man-hours, but also tends to cause poor welding during the welding process, which reduces the good rate of the product, thus increasing known Production cost of backlight module
In addition, since the U-shaped light tube 110 must be connected to the inverter circuit board through the wiring 120 and the connector 130, the wiring 120 and the connector 130 will take up space and increase the cost, and the volume of the known backlight module cannot be reduced.

Abstract

A backlight module comprises an inverter circuit board, a backlight frame, a plurality of light tubes and a plurality of light tube clamp elements. Wherein, the inverter circuit board is provided with a plurality of embedded terminals. The backlight frame is arranged on the inverter circuit board. The light tube is arranged on the backlight frame and each light tube is provided with one electrodeterminal at least. The light tube clamp element is embedded into the backlight frame and is electrically connected with the backlight frame. The electrode terminal is correspondingly and electricallyconnected with the light tube clamp element. Based on these details, the backlight module can be easily assembled.

Description

field of invention [0001] The invention relates to a backlight module, a display device and a clamping component, and in particular to an easy-to-assemble backlight module, a liquid crystal display device and a lamp tube clamping component. Background technique [0002] With the development of the industry, digital tools such as mobile phones, digital cameras, digital video cameras, notebook computers (notebooks) and desktop computers are all becoming more convenient, multi-functional and beautiful. direction of development. When using these information products, the display screen is an indispensable human-machine communication interface, and the display screen of the above-mentioned products will bring more convenience to the user's operation. Among them, liquid crystal display devices have become the mainstream of display screens. However, since the liquid crystal display panel of the liquid crystal display device cannot emit light, a backlight module must be provided u...
