Abstract

The related image display device fit user adjustment comprises: a tuning plate to select transmission signal and send received user command contained gamma adjust command, a digital plate to send the data selected by user and the signal from former plate together, and a drive plate to adjust the sent signal by the send / stored gamma data and output the adjusted signal. This invention can satisfy user visual request.

Description

Technical field [0001] The present invention relates to an image display device, in particular to an image display device and a method for adjusting gamma (Gamma) data which can be easily adjusted by a general user for the picture quality of an image signal output from the image display device. Background technique [0002] Usually, the relationship between the input image signal source and the output signal through the image display device {eg, plasma display panel {PDP (Plasma Display Panel)}, liquid crystal display {LCD (Liquid Crystal Display)}} that displays the input image signal, generally Therefore, in order to compensate the linear relationship of the image signal of the liquid crystal display (LCD) or plasma display panel (PDP) television (TV) itself, the gamma needs to be adjusted. [0003] Here, the so-called gamma adjustment refers to the selection of a gamma compensation value to enhance the black level or the desired image quality of the user in order to set t...
