Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0037] Please refer to figure 1 , figure 1 It is a schematic diagram of the film layer structure of a display device. The display device may include:

[0038] Liquid crystal display panel 01, backlight module 02 and chip-on-chip film 03.

[0039] The backlight module 02 is usually arranged on the side of the liquid crystal display panel 01 away from the light emitting surface.

[0040] One end of the chip-on-film 03 can be electrically connected to the liquid crystal display panel 01, and after the chip-on-film 03 is electrically connected to the liquid crystal display panel 01, the rest of the chip-on-film 03 can be bent so that the backlight module 02 is away from the liquid crystal. One side of the display panel 01 is bond...

Abstract

The invention discloses a display device and a backlight module, and belongs to the technical field of display. The display device comprises a backlight module, a liquid crystal display panel and a chip on film. The backlight module can comprise a frame body, and a lateral light source, a light guide plate, a reflection strip, a light absorption strip and an optical film which are positioned in the frame body. As the light absorption strip is not bonded with the diffusion sheet in the optical film, and the reflection strip is bonded with the diffusion sheet in the optical film, after the chip on film is bent and is bonded with one side, far away from the liquid crystal display panel, of the frame body in the backlight module, the reflection strip is not bonded with the diffusion sheet in the optical film, and the reflection strip is not bonded with the diffusion sheet in the optical film. Under the action of rebound force of the bent part in the chip on film, the diffusion sheet does not move along with the displacement of the light absorption strip, but moves along with the displacement of the light guide plate along with the light absorption strip. It is guaranteed that the light guide plate and the diffusion sheet cannot be separated, and the light emitting effect of the backlight module is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device and a backlight module. Background technique [0002] A liquid crystal display device generally includes: a liquid crystal display panel, a backlight module arranged on the backlight surface of the liquid crystal display panel (that is, the side away from the light-emitting surface), and a driver chip for driving the liquid crystal display panel. [0003] In order to reduce the frame size of the liquid crystal display device, the driving chip in the liquid crystal display device is usually packaged by a chip on film (English: Chip On Flex; COF for short) packaging technology. When chip-on-film technology is used to package the driver chip, one end of the chip-on-film is electrically connected to the LCD panel, and the rest needs to be bent to the side of the backlight module away from the LCD panel, and the backlight module is away from the LCD panel. ...
