摘要： A display apparatus includes a display panel, a gate driver, a gray scale compensator, and a date driver. The gate driver sequentially applies gate data to the gate lines. The gray scale compensator compares the primitive gray scale data of the n-th frame with the primitive gray scale data of the (n−1)-th frame to output a compensated gray scale data of a n-th frame, when a primitive gray scale data of a (n−1)-th frame is lower than a gray scale data of a first gray scale and a primitive gray scale data of the n-th frame is higher than a gray scale data of a second gray scale. The date driver converts the compensated gray scale data into a date voltage corresponding to the compensated gray scale data and applies the data voltage to the date line. Therefore, response time of the liquid crystal molecules may be reduced.

摘要： A display device in which a plurality of pixels are disposed in a matrix form includes data lines connected with the pixels, a signal controller for processing image data received from the outside and generating a plurality of control signals and clock signals, a gray voltage generator for generating a plurality of gray voltages, and a data driver including a plurality of data driver ICs for selecting gray voltages corresponding to image data from signal controller among the gray voltages and applying them as data voltages to data lines, wherein data driver includes four data driver ICs groups and each data driver IC group receives a separate clock signal and includes at least two data driver ICs connected in series with each other is disclosed. Because data driver IC groups receive the separate clock signals a signal delay can be reduced, and because phases of the clock signals are different a harmonic component can be reduced compared with the related art in which the clock signals have no phase difference, and thus EMI can be reduced.

The normal data voltage is sequentially applied to a first gate line set among the plurality of gate line sets, and the impulsive data voltage is sequentially applied to a second gate line set among the plurality of gate line sets. The output image data of the second gray is determined in consideration of luminance display time of a pixel charged by the normal data voltage. Accordingly, luminance deterioration by different luminance display times for respective pixel rows connected to respective gate lines in the gate line set can be prevented.
