Abstract

An overshoot processing (OS processing) of the gray-scale data before it is converted into the data signal of the current frame is performed so that the data after conversion includes the amount of overshoot based on at least the gray-scale data about a predetermined frame prior to the current frame and the gray-scale data about the current frame. A gray-scale correction (delta Vd correction) of the overshoot-processed gray-scale data generated when the overshoot processing of the gray-scale data of the current frame is performed with the amount of correction corresponding to the positions on the display panel of the columns to which the data signal is supplied.

Description

technical field [0001] The present invention relates to techniques for improving the in-plane distribution of display quality of a display panel. Background technique [0002] It is generally known that a feed-through phenomenon (feed through) occurs in an active matrix liquid crystal display device using TFTs in pixel selection elements (see, for example, Non-Patent Document 1). Next, the feedthrough phenomenon will be briefly described. [0003] Figure 5 An equivalent circuit of one pixel is shown. One pixel PIX is provided corresponding to the intersection of the gate bus line GL and the source bus line SL. The pixel PIX generally includes a parasitic capacitance such as a capacitance Cgd formed between the pixel electrode 102 and the gate bus line GL in addition to the TFT 101 , the liquid crystal capacitance Clc, and the auxiliary capacitance Cs. The gate of the TFT 101, the source of the TFT 101, and the drain of the TFT 101 are connected to the gate bus line GL, t...
