摘要： A liquid crystal display system including a signal processing device uses interpolation to generate an intermediate image frame using previous image frame data and present image frame data. The system converts data of the intermediate image frame into transposed image data that is to be used to drive a liquid crystal display panel and display a corresponding image. The transposed image data and the present image data are subjected to a prespecified DCC process (dynamic capacitance compensation process) to thereby generate respective first and second compensation image data. Since the first compensation image data is generated based on the transposed image data and the transposition is configured to prevent over-compensation by the DCC process, over-compensation by the dynamic capacitance compensation process can be reduced or prevented.

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.

The image signal modification unit includes a still image detection unit which receives a previous image signal and a current image signal of two consecutive frames and determines whether the current image signal is for a still image, a first modification unit which receives the current image signal and outputs a first current modified image signal or the current image signal, and a second modification unit which receives the current image signal and outputs a second current modified image signal or the current image signal.

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.

摘要： In a method of compensating image data, a lookup table (LUT) memory storing compensating data that corresponds to received image data is disabled when the received image data is substantially the same as previous image data that is stored in a cache memory. Compensating data that corresponds to the previous image data stored in the cache memory is outputted as compensating data that corresponds to the received image data. The previous image data stored in the cache memory and the compensating data are maintained.
