Problems solved by technology

However, the existing image display device does not consider its characteristics, and does not consider the surrounding temperature, and constitutes a look-up table based on the characteristics of the liquid crystal cell at any temperature such as normal temperature.
[0015] Therefore, even if the overdrive is performed so that the response speed of the liquid crystal cell becomes optimal, if the ambient temperature changes, the above-mentioned problem that the response speed of the liquid crystal cell deviates from the optimal state will occur.

Embodiment Construction

[0030] Below, refer to figure 1 The configuration of an image display device to which the present invention can be applied will be described.

[0031] The controller 100 overall controls the image display device, reads the ODC table corresponding to the ambient temperature from the memory 102 according to an ideal embodiment of the present invention, and then provides the read ODC table to the scaler 106 .

[0032] The memory 102 stores various information including the processing program of the controller 100, and in particular stores the first to Nth ODC tables (1041 ~104N).

[0033] The scaler 106 receives and processes the video signal, and then provides it to the LCD module 110 . In more detail, the scaler 106 saves the input video signal in the picture frame buffer 108 according to each picture frame, and then calculates the gray scale standard change value between the previous picture frame and the current picture frame according to each selection unit, Read the ODC ...

Abstract

The present invention discloses an image display device and a liquid display module drive method, which including: a step of sensing temperature around; a step of reading ODC list corresponding to said temperature sensed from a memory; a step of reading ODC value corresponding to a gray standard change from said ODC list and transmitting it to the liquid display module. In the invention, high quality of image is provided by executing different overexcitations along with the change of environment temperature according to the reaction velocity change of the liquid display module to the change of environment temperature.

Description

1. Technical field [0001] The present invention relates to an image display device, more specifically, an image display device implementing overdrive of a liquid crystal display module and a driving method for the liquid crystal display module. 2. Background technology [0002] Generally, a liquid crystal display device uses an electric field to adjust the light transmission rate of a liquid crystal having dielectric anisotropy to display a picture, and an active matrix (Active Matrix) type liquid crystal display device formed with a thin film transistor as a conversion element of each liquid crystal cell is suitable for displaying stream media. [0003] However, as can be seen from the following mathematical formula 1, due to the inherent viscosity and elasticity of liquid crystal, the liquid crystal display device has the disadvantage of slow response speed. [0004] It can be seen from the following mathematical formula 1 [0005] τr = ...
