Liquid crystal display device and method of driving the same

#This application claims the benefit of Korean Patent Application both Nos. P06-108844 filed on Nov. 6, 2007 and P2007-19574, filed on Feb. 27, 2007, which is hereby incorporated by reference as if fully set forth herein.

#1. Field of the Invention

#The present invention relates to a liquid crystal display device which can decrease the number of source drive integrated circuits ICs used to supply data, and also can decrease a flexible printed circuit and a printed circuit board to supply signals to the source drive integrated circuits ICs in size, and a method of driving the same.

#The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the disclosure and together with the description serve to explain the principle of the invention. In the drawings:

#FIG. 1 is a block diagram of illustrating a liquid crystal display device according to the related art;

#FIG. 2 is an equivalent circuit diagram of equivalently illustrating a thin film transistor TFT array substrate with a ‘4×4’ matrix of liquid crystal cells in a liquid crystal panel shown in FIG. 1;

#Reference will now be made in detail to the preferred embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

#Hereinafter, a liquid crystal display device according to the preferred embodiment of the present disclosure and a method of driving the same will be explained with reference to FIGS. 8 to 25.

#Referring to FIG. 8, the liquid crystal display device according to the preferred embodiment of the present disclosure includes ‘m’ gate lines G1 to Gm arranged along a long-axis direction (X-axis direction) of a pixel array 10 of a liquid crystal panel 6; ‘n’ data lines D1 to Dn arranged along a short-axis direction (Y-axis direction) of the pixel array 10 of the liquid crystal panel 6, wherein each of the data lines D1 to Dn is orthogonal to each of the gate lines G1 to Gm; a gate driving circuit 2 directly formed on a glass substrate of the liquid crystal panel 6; source drive integrated circuits ICs 1a and 1b included in a data driving circuit adhered to the glass substrate of the liquid crystal panel 6 by a COG or TCP type; and an FPC 5 connected between the liquid crystal panel 6 and a source PCB 4.
