Embodiment Construction

[0026] The specific implementation of the flexible flat cable and the driving structure of the thin film transistor liquid crystal display panel provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] see image 3 , The flexible flat cable of the present invention includes a body 30 and terminals 31 disposed at both ends of the body 30 . In this specific embodiment, two terminals 31 are included, and the two terminals 31 are arranged oppositely at both ends of the body 30, for connecting with the control board 40 (see FIG. 5 ) and the printed circuit board 42 (see FIG. 5 ). ) The connector 45 (see FIG. 5) in the electrical connection.

[0028] The body 30 includes a conductive metal wire (not shown in the drawing) and a base material (not shown in the drawing) covering the conductive metal wire, and the conductive metal wire is connected to the terminal 31 .

[0029] Each terminal 31 is provided with a clamp...

Abstract

The present invention provides a flexible flat cable and film transistor liquid crystal display panel driving structure. The flexible flat cable comprises a body and terminals arranged at both ends of the body; the end part of each terminal away from the body is provided with a clamping structure; the clamping structure includes an inner side straight edge facing the inner side of the end part of the terminal, an outer side edge facing the outer side of the end part and a bottom edge that connect the inner side straight edge and the outer side edge. The bottom edge is connected to the end part of the terminal. The beneficial effect of the invention lies in the extra clamping structures on a flexible flat cable. The inner side straight edge of a clamping structure is utilized to have a flexible flat cable fastened so as to prevent left-right displacement, thus preventing the flexible flat cable plug from crooked insertion and reducing the possibility that a PCB is burned due to the crooked insertion of the flexible flat cable.

Description

technical field [0001] The invention relates to the field of liquid crystal display panels, in particular to a flexible flat cable and a driving structure of a thin film transistor liquid crystal display panel. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor Liquid Crystal Display) is one of the main varieties of flat panel display, and has become an important display platform in modern IT and video products. [0003] see figure 1 , the main driving principle of TFT-LCD is that the main board of the system connects the R / G / B compressed signal, control signal and power with the connector (connector) 11 on the control board (Control Board) 10 through wires, and the data passes through the control board 10 After being processed by TCON (Timing Controller, timing controller) IC (not marked in the drawings), it is transmitted to PCB board 13 and PCB board 14 through FFC (Flexible Flat Cable) 12, and then passed through S-C...
