Description

A kind of liquid crystal display module with novel FPC bending structure

Technical field

The utility model relates to a kind of liquid crystal display module with novel FPC bending structure.

Background technology

Existing liquid crystal display module, its FPC[flexible print circuit] by a connecting portion, be connected with screen body, the lower end of connecting portion is linear pattern, as shown in Figure 1, in FPC when bending, is easily along this section of lower end this edge edge line of connecting portion, cause product bad, therefore, be necessary to design a kind of liquid crystal display module with novel FPC bending structure.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of liquid crystal display module with novel FPC bending structure, and this liquid crystal display module bend resistance performance with novel FPC bending structure is good, easy to implement.

The technical solution of utility model is as follows:

A liquid crystal display module with novel FPC bending structure, comprises screen body and FPC, and described FPC comprises FPC main body (1), for connecting the golden finger (2) of mainboard and connecting portion (3) for being connected with screen body; FPC main body is square schistose texture, and described golden finger is arranged on the end of FPC main body lower end extension; Described connecting portion is arranged on the upper edge place of FPC main body;

Described connecting portion is square schistose texture, and connecting portion has a corrugated base.

Described extension is the sheet flexible printed circuit board with 90 ° of bendings.

Beneficial effect:

The liquid crystal display module with novel FPC bending structure of the present utility model, its connecting portion adopts unique waveform base design, thereby FPC bending time, shearing force does not concentrate on a line, but be distributed on the face that wavy edge is attached to FPC main body, thereby bend resistance performance is good, and this connecting portion with waveform base is easy to processing, be easy to realize, this novel connecting portion can significantly strengthen reliability and the yield rate of liquid crystal display module.
