Backplane and liquid crystal display device

Abstract

The invention discloses a backplane and a liquid crystal display device. The backplane is formed by splicing at least two sub-backplanes. The splicing part of the sub-backplanes is provided with a plurality of vertical complementary parts perpendicular to the splicing section of the splicing part. Reinforcing ribs, the vertical reinforcing ribs are arranged along the splicing section. In the present invention, the backplane is formed by splicing multiple sub-backplanes without using large stamping equipment or large molds, thereby reducing the production cost of the backplane; in addition, the present invention uses multiple sub-backplanes for splicing, which can target The side with high heat generation on the backboard is made of materials with good heat dissipation performance, and for the side with low heat generation, only ordinary materials with sufficient strength are needed, which saves costs; At the joint, a number of vertical reinforcing ribs perpendicular to the joint section of the joint are added, which improves the strength of the joint and the vertical strength of the back plate, thereby improving the flatness of the back plate and improving the stability of the liquid crystal display device. Display quality.

Description

technical field [0001] The invention relates to the field of liquid crystal display, more specifically, to a back plate and a liquid crystal display device. Background technique [0002] The LCD modules currently in mass production all use integral backplanes. Generally, it is made of the same material, which is aluminum plate, iron plate or plastic, and the processing method is mostly stamping or plastic injection integral molding, which makes the product heavier and the material cost of the product is higher. Large-sized products need to use larger stamping equipment, the cost is high, the corresponding mold size is large, the structure is complex, and the mold cost is also high. If the entire backplane is made of iron plate or plastic, heat dissipation elements need to be added, which increases the cost; if aluminum plate is used, no additional heat dissipation elements are used. Only a part of the plate plays the role of heat dissipation, and the other part does not pl...

Problems solved by technology

Large-sized products need to use larger stamping equipment, the cost is high, the corresponding mold size is large, the structure is complex, and the cost of the mold is also high

If the entire backplane is made of iron plate or plastic, heat dissipation elements need to be added, which increases the cost; if aluminum plate is used, no additional heat dissipation elements are used. Only a part of the plate plays the role of heat dissipation, and the other part does not play the role of heat dissipation but supports the role. Moreover, the price of the aluminum plate is relatively expensive, and the material cost is relatively high.
