Problems solved by technology

[0009] In the above-mentioned prior art flexible circuit board 1, the conductive pattern 120 on the input side and the conductive pattern 140 on the output side are both rectangular, and in order to prevent a short circuit, a certain distance must be kept between each conductive pattern, so when the number of driving signals increases , it is necessary to increase the area of ​​the printed circuit board joint part 12 and the liquid crystal panel joint part 14 of the substrate 10 to accommodate a greater number of conductive patterns, and this will inevitably lead to an increase in the width of the flexible circuit board 1, which is not conducive to liquid crystal The thinning and lightening of the display

Abstract

The present invention relates to a kind of soft circuit board, which has input side conducting pattern with average width smaller than the maximum width, output side conducting pattern with average width smaller than the maximum width, input side conducting pattern with closely set smaller width part and greater width part, and output side conducting pattern with closely set smaller width part and greater width part. Under the condition of the same width, the soft circuit board of the present invention has even great capacity of transmitted signal compared with available technology. The LCD with the soft circuit board of the present invention is light and thin.

Description

【Technical field】 [0001] The invention relates to a flexible circuit board (Flexible Circuit Board) and a liquid crystal display (Liquid Crystal Display, LCD) using the flexible circuit board. 【Background technique】 [0002] Generally, a liquid crystal display modulates light passing through a liquid crystal layer by applying a voltage to the liquid crystal molecules to change the arrangement of the liquid crystal molecules. According to different driving methods, liquid crystal displays are divided into active matrix type and passive matrix type. A TFT-LCD driven by a TFT (Thin Film Transistor, thin film transistor) has a relatively simple circuit and is widely used in calculators. [0003] A general TFT-LCD includes a liquid crystal panel, a backlight module arranged on the rear surface of the liquid crystal panel, and a source part and a gate part arranged on the liquid crystal panel. The source part includes a source driver IC for applying image data to display images,...
