Liquid crystal display

Abstract

A disclosed display includes a display panel including a first group of data lines and second group of data lines, a plurality of gate lines crossing the first and a second groups of data lines, and a plurality of picture cells arranged in a matrix. The display also includes a first source PCB coupled to first data integrated circuits (ICs) to supply first data voltages to the first group of data lines and a second source PCB coupled to second data ICs to supply second data voltages to the second group of data lines. The display further includes a timing controller having a single output port with a plurality of output pins which are configured to output video data to both the first and second data ICs, and to output a timing control signal to control both the first and second data ICs. In addition, the display includes a first connection cable coupling the single output port of the timing controller to at least one of the first and second source PCBs to transmit the video data and the timing control signal from the timing controller to the at least one of the first and second source PCBs. The first data ICs and second data ICs are configured to generate the first and second data voltages, respectively, based on the video data and the timing control signal.

Description

[0001] This application claims Korean Patent Application No. P2007-26070 filed on March 16, 2007; Korean Patent Application No. P2007-0030332, P2007-0030323, P2007-0030333, and P2007- 0030454; the benefit of Korean Patent Application Nos. P2007-0046113 and P2007-0046126 filed May 11, 2007, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device with a simplified control printed circuit board (PCB). Background technique [0003] A liquid crystal display (LCD) device controls light transmittance of a liquid crystal cell according to a video signal to display an image. The active matrix type LCD device actively controls data by switching the data voltage supplied to the liquid crystal cell using a thin film transistor (TFT) formed in each liquid crystal cell C1c, such as figure 1 shown. Thus, it is possible to improve ...

Problems solved by technology

Thus, the number of output pins of the timing controller 131 needs to be twice that of the conventional structure using a single source PCB, which results in increased size and higher cost of the timing controller 131 and the controller 140
