Problems solved by technology

[0010] In addition, since the generally used driver IC does not have the input terminals shown in Fig. 4, it is necessary to newly design and manufacture the driver IC shown in Fig. 4
Thus, it takes time and cost to develop such a new driver IC with input terminals

Embodiment Construction

[0076] Refer below Image 6 A first embodiment of the present invention is given. Image 6 is a plan view of the liquid crystal display device according to the first embodiment of the present invention. exist Image 6 In FIG. 1, the same parts as those shown in FIG. 1 are denoted by the same reference numerals, and descriptions thereof are omitted.

[0077] A liquid crystal display device 30 according to the first embodiment of the present invention includes a liquid crystal panel 2, source side and gate side flexible plates 32 and 34 on which source side and gate side driver ICs 4-1 and 4-2 are respectively mounted, and Connection plate 36 . The source-side and gate-side flexible plates 32 and 34 are directly connected to the liquid crystal panel 2 . That is, the liquid crystal display device 30 according to the present embodiment does not have the circuit boards 8 and 10 shown in FIG. 1 .

[0078] Therefore, the input signal lines formed on the circuit boards 8 and 10 sho...

Abstract

A liquid crystal display device converts an input signal into a liquid crystal driving signal to display an image on a liquid crystal panel. A large number of flexible boards are connected to the liquid crystal panel, and each flexible board has a driving IC that converts the input signal into a liquid crystal driving signal. The connection board is connected to the liquid crystal panel to provide input signals to first input lines formed on the liquid crystal panel. Each flexible board has a second input signal line for providing an input signal to the driver IC; a first end of each second input signal line is connected to each of the first set of first input signal lines. The second end of each second input signal line is connected to each of the first input signal lines of the second group, the second group of first input signal lines is formed differently from connecting the first end of the second input line to the first input signal line. The location of the first set of input line locations.

Description

[0001] This application is a divisional application of Chinese Patent Application No. 02123713.1 filed on March 20, 2002, entitled "LCD Display Device with Driver IC Mounted on a Flexible Board Directly Connected to a Liquid Crystal Display Panel". technical field [0002] The invention relates to a liquid crystal display device, in particular to a connection technology between a circuit board and a liquid crystal panel of the liquid crystal display device. Background technique [0003] A conventional liquid crystal display device includes a liquid crystal panel and a plurality of driving integrated circuits (driver ICs) that drive the liquid crystal panel. FIG. 1 is a plan view of a conventional liquid crystal display device. [0004] The liquid crystal display device shown in FIG. 1 includes a liquid crystal panel 2, a plurality of source-side driver ICs 4-1, and a plurality of gate-side driver ICs 4-2. Liquid crystal display signals are supplied from an external circuit ...
