Abstract

The invention discloses a backlight module, comprising a back board, a reflector plate, a lamp tube support and a plurality of light tubes. The back board is provided with a plurality of broken holes, an inner surface and an outer surface. The reflector plate is arranged on the inner surface and is provided with a plurality of openings, and the openings are exposed partially on the broken holes. The lamp tube support comprises a substrate and a plurality of bearing parts, and the bearing parts are connected with the substrate; the substrate is arranged on the outer surface of the back board, and the bearing parts pass through the broken holes of the back board and the openings of the reflector plate; the lamp tubes are clamped among the bearing parts so that the lamp tubes and the substrate are respectively positioned at two sides of the back board, thereby completely and flatly pasting the reflector plate on the inner surface of the back board, having good reflection effect of the flat reflector plate, and providing light source which is distributed more evenly by the backlight module. In addition, the design of the lamp tube support is favorable for narrowing a distance between the lamp tubes and the back board, thereby having the characteristic of thinness of the backlight module.

Description

technical field [0001] The invention relates to a structure of a backlight module, and in particular to a configuration means of a lamp tube support frame in the backlight module. Background technique [0002] With the development of the industry, digital tools such as mobile phones, digital cameras, digital video cameras, notebook computers and desktop computers are all more convenient, multi-functional and development in an aesthetic direction. When using these information products, the display screen is an indispensable human-machine communication interface, and the display screen of the above-mentioned products can 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 under the liquid crystal display panel to provide a light source to achieve the di...
