Embodiment Construction

[0040] Hereinafter, a liquid crystal display according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0041] image 3 is a block diagram showing a liquid crystal display according to an embodiment of the present invention.

[0042] refer to image 3 , a liquid crystal display 500 according to an embodiment of the present invention includes a liquid crystal display panel assembly 100 and a backlight assembly 200 .

[0043] The liquid crystal display panel assembly 100 has a predetermined effective display area, and precisely controls the liquid crystal of the liquid crystal display 500 by controlling the liquid crystal of a minute area. The backlight assembly 200 provides light to the liquid crystal display panel assembly 100 .

[0044] Fig. 4a is a schematic plan view of a liquid crystal display according to an embodiment of the present invention.

[0045] Referring to FIG. 4a, the liquid crysta...

Abstract

Disclosed are a liquid crystal display device and a method for driving the same. After all the gate lines included in each effective display region divided into several regions, are turned on, a light is supplied to a liquid crystal after all the liquid crystals are completely arranged, but the light is not applied to a portion of the effective display regions until all the liquid crystals are completely arranged. The process is repeatedly performed concerning each effective display region. Thus, the poor quality of display image such as image spreading phenomenon of the moving image can be prevented. Also, the light supply time can greatly increase, thereby accomplishing an image display with a high brightness.

Description

technical field [0001] The present invention relates to a liquid crystal display and a method for driving the liquid crystal display, and more particularly to a liquid crystal display suitable for accurately displaying moving images and a method for driving the liquid crystal display. Background technique [0002] Generally speaking, a liquid crystal display displays images including text, still images, and moving images. To display these images, LCDs precisely control tiny areas of liquid crystals. The light transmittance of the liquid crystal varies according to the strength of an electric field applied thereto. [0003] Generally, a liquid crystal display includes an electrode facing a pixel, a common electrode facing, and a liquid crystal formed between the two electrodes. The pixel electrodes formed on the facing substrate are divided to have a matrix form and minute regions are formed on the facing substrate. Electric power (electric power) is applied to the pixel e...
