Problems solved by technology

[0005] However, in practice, in addition to complicated wiring and difficult assembly, the method of connecting using connecting wires often has the problem of wire management that the connecting wires are not easy to fix and the connecting wires are easy to tangle.
[0006] What's more, due to the large variety of LED bulbs or LED modules currently provided by LED suppliers, the application design of LEDs in backlight modules is relatively complicated.
When designers use these various types of LED modules, they also need to consider their respective wiring methods, which makes the design more complicated
In addition, the different fixing methods of connecting wires also increase the difficulty of assembly

Embodiment Construction

[0026] Please refer to FIG. 1A , which is a schematic side view of a preferred embodiment of the backlight module disclosed in the present invention. FIG. 1B is an exploded schematic view of the main components in FIG. 1A . In this embodiment, the backlight module 1 includes a backplane 10 , an LED circuit board 11 , an LED 12 and a driving circuit board 13 .

[0027] The back bezel 10 (back bezel) can be made of aluminum, plastic or various materials, and its periphery has side walls, and forms a shallow groove-like accommodation space. In general, the backlight module also has a frame (frame) 14, which can be assembled with the backplane 10, and can accommodate such as LED circuit board 11, LED 12, or other optical components (such as diffusion plate, reflector) placed in it. In addition, in this embodiment, the backplane 10 also has a through hole 101 passing through the backplane.

[0028] The light-emitting diode circuit board 11 can be various substrates (such as prin...

Abstract

This invention discloses a backlight module, which contains LED circuit board, LED and driving circuit board, wherein the LED circuit board including first and second surface with first connection head, LED connected with first connection heat, the second connection head set on driving circuit board, the second connection head can be jointed with first connection head, directly assembling driving circuit board with LED circuit board for driving the LED without wire connection.

Description

technical field [0001] The invention relates to a backlight module, in particular to a backlight module which can be assembled conveniently. Background technique [0002] Nowadays, liquid crystal display has been widely used in various information display devices. Its main structure can be divided into two parts: liquid crystal panel and backlight module. The liquid crystal panel roughly includes ITO conductive glass substrate, liquid crystal layer, alignment film, color filter plate, polarizer and other components; the backlight module mainly includes a light source, light guide plate, prism sheet, diffuser plate, reflector sheet and various optical films, and provides light source to the LCD panel through the backlight module to achieve the purpose of information display. The overall characterization of an LCD product is affected by the interaction of all internal components, with the backlight module playing an important role in screen brightness, uniformity, contrast and...
