AI Technical Summary

Problems solved by technology

It is difficult to realize the synchronization of the driver IC when the driver IC has no external synchronization signal but internally generates the driver control signal
For this reason, in conventional cases, there may be a decrease in image quality due to wrong drive timing and a decrease in product reliability due to the decrease in image quality

Abstract

An apparatus and method for driving an image display device are disclosed. The disclosed driving apparatus and method achieve synchronous driving of driving integrated circuits for driving an image display panel, through internal generation of drive control signals, thereby preventing a degradation in picture quality caused by erroneous driving timing while achieving an enhancement in product reliability. The driving apparatus includes a display panel, which includes a plurality of pixel regions, to display an image, a plurality of data integrated circuits, which share at least one of synchronizing signals internally generated therefrom, generate gate and data control signals in accordance with the shared synchronizing signal, and drive data lines of the display panel, using the internally-generated data control signals, and a gate driver for driving gate lines of the display panel in accordance with the gate control signal generated from one of the plural data integrated circuits.

Description

technical field [0001] The present invention relates to an image display device, and more particularly, the present invention relates to an apparatus and method for driving an image display device, which can realize synchronous driving of a driving integrated circuit for driving an image display panel by internally generating a driving control signal, thereby Prevents image quality degradation caused by erroneous drive timing and improves product reliability. Background technique [0002] In recent years, various types of image display devices have been proposed as a means of displaying digital content. Among the proposed image display devices, flat panel display devices are most commonly used. Such a flat panel display device is, for example, a liquid crystal display device, an organic light emitting device, a field emission display device, a plasma display panel, or the like. [0003] For a conventional image display device in which a plurality of pixels are arranged on ...
