Back plate of liquid crystal display module and splice structure thereof

Abstract

The present invention discloses a back plate of a liquid crystal display (LCD) module and a splice structure thereof. The back plate is assembled at least by a first back plate portion and a second back plate portion, wherein at least one splice structure is defined between the first back plate portion and the second back plate portion, and the shapes of two sides of the splice structure are correspondingly engaged with each other. Besides, the convex portion is provided with a fixing hole thereon, and the concave step portion is correspondingly provided with a fixing pillar therein. The fixing pillar passes through the fixing hole to fix the first back plate portion and the second back plate portion. The present invention can use different type of material to assemble into the back plate, so as to intensify the splicing strength except for decreasing the material cost.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a back plate of a liquid crystal display (LCD) module, and more particularly to a splice structure of a back plate of an LCD module.BACKGROUND OF THE INVENTION[0002]A liquid crystal display (LCD) is a kind of flat panel display (FPD) which displays images by the property of the liquid crystal material. In comparison with other display devices, the LCD has the advantages in lightweight, compactness, low driving voltage and low power consumption, and thus has already become the mainstream product in the whole consumer market. However, the liquid crystal material of the LCD cannot emit light by itself, and must depend upon an external light source. Thus, the LCD further has a backlight module to provide the needed light source.[0003]An assembly of a traditional LCD module is mainly to load a light guide plate into a back plate, wherein the light guide plate is provided with an optical film assembly, and then a plastic frame c...

AI Technical Summary

Benefits of technology

The present invention allows for the use of different materials to make the back plate of an LCD module, which increases the strength of the splicing but decreases the cost of the materials used.

Problems solved by technology

However, the liquid crystal material of the LCD cannot emit light by itself, and must depend upon an external light source.

If the entire back plate uses the aluminum material, the cost is too high, and the structure strength is worse; but if the entire back plate uses the zinc-plated steel plate, the heat-dissipation is worse and the performance of product will be lowered.
