摘要： A liquid crystal display includes a plurality of gate lines and a plurality of data lines crossing over the gate lines while being electrically insulated from the gate lines. Pixels are placed at the cross regions of the gate and the data lines arranged in a matrix form. Each pixel has a switching circuit connected to the gate and the data lines. Data voltages are fed to the pixels such that the polarity of the pixels is inverted per a pixel group of two or more pixel rows. Gate voltages are applied to the neighboring first and second pixel groups such that the gate voltage applied to the pixel row of the first pixel group close to the second pixel group differs from the gate voltage applied to the pixel row of the first pixel group distant to the second pixel group.

摘要： A direct type backlight unit is disclosed. The direct type backlight unit includes a plurality of lamps arranged in a plane with respect to a display area, a diffusion sheet and a diffuser sequentially arranged above the plurality of lamps, and dot patterns formed on at least one of the diffuser and the diffusion sheet to face the plurality of lamps, wherein the dot patterns disperse light at a center of the plurality of lamps and condense the light in a boundary between the plurality of lamps. Thus, an effect for removing a shape display of the lamps on an LCD panel can be obtained to improve display quality. Also, since the dot patterns are formed by a printing method, no separate prism pattern is required. As a result, the material cost can be reduced and stability in mass production can be obtained.

摘要： A gamma voltage generator for a liquid crystal display (LCD) capable of removing residual images by compensating a gamma voltage is presented. The gamma voltage generation apparatus adjusts the common voltage by the kickback voltage for the intermediate gray level, and tunes the gamma voltages other than the intermediate gray level gamma voltage. The adjustment of the gamma voltages other than the intermediate gray level gamma voltage is achieved in such a manner that the difference between the intermediate gray level kickback voltage and the kickback voltage at one of the gray levels other than the intermediate gray level is equal to half of the difference between the sum of the two inverted gamma voltages representing the intermediate gray level gamma voltages and the sum of the two inverted gamma voltages corresponding to the selected gray level.

摘要： A liquid crystal display (“LCD”) device includes an LCD panel, a data driver and a gate driver. The LCD panel includes a first pixel section and a second pixel section formed in regions defined by a adjacent gate lines and adjacent data lines. The first pixel section is electrically charged at a first time point and the second pixel section is electrically charged at a second time point later than the first time point. The data driver provides the data lines with data voltages. The gate driver applies a first gate signal to the first pixel section, and a second gate signal having at least one different characteristic from that of the first gate signal to the second pixel section. Therefore, vertical flickering may be prevented in the LCD device.
