A display apparatus includes a display part, a signal control part, data driving parts, and first and second wiring pairs. The display part includes pixels. The signal control part includes a transmission part that converts an image signal into a multi-level signal. The data driving parts receive the multi-level signal from the transmission part, convert the multi-level signal into a reproduced image signal and provide the pixels with the reproduced image signal. The first and second wiring pairs connect the transmission part and at least one data driving part of the data driving parts. The multi-level signal includes serial data of the image signal and an embedding clock embedded in the serial data. A voltage level of the serial data in the multi-level signal is different from a voltage level of the embedding clock in the multi-level signal.

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.

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.

A liquid crystal display includes a pixel, an image signal modification unit and a data driver. 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. The data driver changes the second current modified image signal or the current image signal into a data voltage and supplies the data voltage to the pixel. The first modification unit outputs the current image signal when the current image signal is determined to be for the still image.
