Problems solved by technology

[0009] Moreover, since the writing time of each pixel is reduced as the number of pixels of the entire display device is increased, and the parasitic capacity of each source wiring is weakened, it is difficult to write an image signal. accomplish
Therefore, there is a problem of insufficient processing capability or current driving capability of the excitation part, and there is also a problem that a high-performance and expensive excitation part needs to be used in this case.

Abstract

A liquid crystal display having a plurality of source lines in the display area which are each divided into two groups includes a first source driver for applying image signals to a first group of the divided source lines, a second source driver for applying image signals to a second group, a first gate driver operative to apply scanning signals to one segment of a plurality of gate lines that extends across the first group of the divided source lines, and a second gate driver for applying scanning signals to the other segment of a plurality of gate lines that extends across the second group of the divided source lines, and switching assemble.

Description

technical field [0001] The invention relates to a liquid crystal display device and a corresponding driving method, in particular to an active matrix driven liquid crystal display device suitable for high-definition display. Background technique [0002] In the field of liquid crystal display (Liquid Crystal Display, hereinafter abbreviated as LCD) technology that can be applied to various electronic devices, in recent years efforts have been made to improve image quality so as to realize high-definition display. For a liquid crystal display device (LCD) that uses a thin film transistor (Thin Film Transistor, hereinafter abbreviated as TFT) at each pixel switching element and operates according to a thin film transistor (TFT) type active matrix drive method, in order to achieve high-definition Display needs to reduce the pixel pitch and increase the number of pixels accordingly. It has been proposed that several signal lines (source lines) and several integrated circuit (IC)...
