A side-light backlight module and a liquid crystal display device using the backlight module

Abstract

The invention discloses a side-light backlight module and a liquid crystal display device using the backlight module. The backlight module includes a backplane, a cooling plate, and at least one light-emitting diode strip. The bottom plate of the backplane has a first surface and The second surface and a first through hole, the heat dissipation plate is arranged on the first surface, the side of the heat dissipation plate is provided with a first opening, the bottom of the heat dissipation plate includes a bent portion and a horizontal portion, the bent portion The folded part and the first surface form a first accommodating space, the horizontal part abuts against the first surface, and a first through groove is arranged on the horizontal part; the light emitting diode light bar includes a circuit board, a plurality of light emitting diodes and the first connector, the wires connected to the first connector pass through the first accommodating space, the first through groove and the first through hole from the first surface of the base plate to the base plate in sequence The second surface of the second surface, thereby improving the wire management and the fixing structure of the wire in the prior art.

Description

[0001] This application is a divisional application filed on February 28, 2012 with the application number 201210047969.5 and the title of the invention entitled "A side-light backlight module and a liquid crystal display device using the backlight module". technical field [0002] 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 [0003] 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. [0004] The backlight modules commonly used in the prior art are divided into side-light b...

AI Technical Summary

Problems solved by technology

[0006] 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

[0007] 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
