Abstract

The invention relates to a LCD that mainly comprises a liquid crystal display panel and a flexible circuit board which is connected with the edge of the liquid crystal display panel. The flexible circuit board includes a major component and a coupling part. The major component is the circuit transmission part of the flexible circuit board it includes a reinforced branch which is a branched structure extended from the major component. The coupling part and the major component are an integral body and connected by circuit. The flexible circuit board of the LCD is non-disrupted or tearing.

Description

【Technical field】 [0001] The invention relates to a flexible printed circuit and a liquid crystal display using the flexible printed circuit. 【Background technique】 [0002] Currently, the methods for connecting the LCD panel to the driver IC include COG (Chip On Glass, Chip On Glass) technology, TAB (Tape Automatic Bonding, Tape Automatic Bonding) technology and COF (Chip On Film, Chip On Film) technology. [0003] Among them, the COG technology can be used to directly install the driver IC in the form of a semiconductor package on the gate line and data line of the liquid crystal panel, so as to transmit the electrical signal to the liquid crystal panel. The driver IC is bonded to the liquid crystal panel with an anisotropic conductive film. [0004] In addition, the TAB technology can be used to directly connect the liquid crystal panel to the printed circuit board through the tape carrier package (Tape Carrier Package), and the driver IC can be mounted on the tape carri...
