Abstract

The present invention provides a backlight module and a display device using the same. A display device comprises the backlight module and a liquid crystal display panel arranged on the backlight module. The backlight module comprises a frame, wherein the frame comprises a frame body and a load-bearing part. The frame body is located at the periphery of the load-bearing part and is connected with the load-bearing part, and the load-bearing part possesses a first surface and a second surface relative to the first surface. The corner of the first surface corresponding to the load-bearing part is a right angle, and the position of the second surface corresponding to the corner is an arc angle, and the projection position of the arc angle on the first surface is located between the right angle and the outer edge of the load-bearing part.

Description

technical field [0001] The invention relates to a frame, in particular to a backlight module and a display device using the backlight module. Background technique [0002] Due to the advantages of liquid crystal display (Liquid Crystal Display, LCD) compared with cathode ray tube (Cathode Ray Tube, CRT) display, which is thinner, lighter in weight, more convenient to carry, and lower in radiation, the demand has increased rapidly in recent years. Especially the backlight module (Backlight Module) is one of the key components of the liquid crystal display device. With the improvement of manufacturing technology of liquid crystal display devices, the backlight module is developing towards the market direction of thinner shape, higher brightness and lower cost. In order to maintain the competitiveness of the liquid crystal display device in the future market, developing and designing a better quality backlight module is the direction that needs to be worked hard in the future....
