Embodiment Construction

[0037] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0038] figure 1 It is a schematic diagram of using screws to lock the LED light bar 2 and the reflector 4 in the prior art, such as figure 1 As shown, since the PCB (printed circuit board) of the LED light bar 2 has a certain thickness, if the screws are not locked properly or are too tight, the LED light bar 2 will be warped, which will affect the display effect of the picture. Moreover, locking the screws will reduce the production efficiency, and the required material and labor costs are high, which is particularly obvious in large-size direct-lit display devices.

[0039] The embodiments of the present invention aim at the above-mentioned problems, and provide a backlight module and a display device, which can solve the problems o...

Abstract

The invention provides a backlight module and a display device and belongs to the technical field of display. The backlight module comprises a backing plate and LED light bars fixed on the backing plate; and the LED light bars are adhered to the backing plate by a plurality of first adhesion bodies. The invention can solve problems that in the prior art, a direct-lit type backlight module adopts ascrew locking mode, is low in production efficiency and requires high material and labor cost and a reflective sheet is easy to upwarp to cause light shadow, and further solves a problem that the position of a screw hole influences aesthetics of the back of a display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal panel and a backlight module. Since the liquid crystal panel itself does not emit light, the light source provided by the backlight module is needed to display images normally. Therefore, the backlight module is one of the key components of the liquid crystal display device. Backlight modules are divided into side-type backlight modules and direct-type backlight modules according to the incident position of the light source. [0003] Most of the existing direct-type backlight modules directly or indirectly fix the LED (light-emitting diode) light source and the reflector by screw locking. This method not only has low production efficiency and high labor costs, but al...
