Embodiment Construction

[0042] A preferred embodiment of the present invention will be described in detail below with reference to FIGS. 5 to 8. FIG. Fig. 5 shows a liquid crystal display according to an embodiment of the present invention.

[0043] As shown in FIG. 5 , the liquid crystal display includes a liquid crystal display panel 12 in which liquid crystal cells are arranged in a matrix. The gate driver 16 drives a plurality of gate lines G0 to Gn of the liquid crystal display panel 12 . The data driver 14 drives a plurality of data lines DL1 to DLm / 2 of the liquid crystal display panel 12 .

[0044] In the liquid crystal display panel 12, the data lines DL1 to DLm / 2 are isolated from and cross the gate lines G0 to Gn. The liquid crystal display panel 12 also includes liquid crystal cells formed between the pixel electrodes and the common electrodes. Since the pixel electrodes are arranged on the liquid crystal display panel 12 in a matrix, the liquid crystal cells are also arranged on the l...

Abstract

A liquid crystal display suitable for reducing the number of data lines and driving circuits. This LCD can be driven in a dot matrix switching method using a data driver using a column switching method. The gate driver sequentially supplies the first and second gate signals to the gate lines. The first and second switching elements are located in the i-th horizontal line, and supply video signals from the data lines to the LC cells by controlling the i-th gate line. The third switching element provides video signals to units located in the horizontal line, is connected to the same data line as the second switching element, and is controlled by the i-th and i-1th gate lines. The fourth switching element provides video signals to units located in the horizontal line, is connected to the same data line as the first switching element, and is controlled by the i-th and i-1th gate lines.

Description

[0001] This application claims priority under 35 U.S.C. §119(a) to Patent Application No. P2003-99805 filed in Korea on December 30, 2003, the entire contents of which are hereby incorporated by reference. technical field [0002] The invention relates to a liquid crystal display, in particular to a liquid crystal display suitable for reducing the number of data lines and data-driven integrated circuits corresponding to the data lines. The liquid crystal display of the present invention can be driven with a dot matrix switching system using a data driver using a column switching method. Background technique [0003] Liquid crystal displays use electric fields to control the light transmittance of liquid crystal materials to display images. Therefore, the liquid crystal display includes a liquid crystal display panel, which has a pixel matrix and a driving circuit for driving the liquid crystal display panel, and the driving circuit drives the pixel matrix to display image in...
