Problems solved by technology

[0005] It can be seen from this that the wire management and fixing structure of the edge-lit backlight module in the prior art is relatively complicated, and the manual operation is cumbersome. Broken and separated from the connector, resulting in product scrapping, even rework is time-consuming
[0006] In the prior art, in order to fix the LED light bar and the heat sink together, the common practice is to set a plurality of hole structures on the circuit board of the LED light bar, and the positions of the hole structures are two adjacent light-emitting diodes. Set screw holes at the corresponding positions of the heat sink, and then use screws to pass through the hole structure and the screw holes to fix the LED light bar and the heat sink together. The display screen of the display device is defective

Abstract

The invention discloses an edge-lit backlight module and a liquid crystal display device with the same. The backlight module comprises a back plate, a radiating plate and at least one light emitting diode strip. A bottom plate of the back plate is provided with a first surface, a second surface and a first through hole. The radiating plate is disposed on the first surface. The lateral edge of the radiating plate is provided with a first opening. The bottom edge of the radiating plate comprises a bent part and a horizontal part, the bent part and the first surface form a first containing space, the horizontal part is mutually abutted to the first surface, and a first through channel is reserved on the horizontal part. Each light emitting diode strip comprises a circuit board, a plurality of light emitting diodes and a first connector. A wire connected to the first connector sequentially passes through the first containing space, the first through channel and the first through hole and passes from the first surface of the bottom plate to the second surface of the bottom plate. Therefore, wire arrangement and wire fixing structures in the prior art are improved.

Description

technical field [0001] The invention relates to a backlight module, in particular to a side-light backlight module and a liquid crystal display device using the side-light backlight module. Background technique [0002] With the continuous development of liquid crystal display technology, liquid crystal display products have been widely used in various fields of life. However, the liquid crystal itself does not emit light, and a light source needs to continuously provide light to the liquid crystal display screen to realize image display. In liquid crystal display products, a backlight module is usually selected to provide light. [0003] The backlight modules commonly used in the prior art are divided into side-light backlight modules and direct-light backlight modules according to the position of the light source. The advantage of the side-light backlight module is that it can reduce the overall thickness of the liquid crystal display device. Optical backlight modules are...
