Abstract: In a control board and a display apparatus, the control board includes a timing controller, and first and second connectors. The timing controller receives a first external image control signal having one of a first and a second frequency, and selectively receives a second external image control signal having the first frequency when the first external image control signal has the first frequency. The timing controller selects one of the first and second frequencies based on the first and second external image control signals to output an image driving signal. The first connector connects the timing controller to an external video system to transfer the first external image control signal to the timing controller. The second connector connects the timing controller to the external video system to transfer the second external image control signal to the timing controller. Thus, the control board is commonly used in the first and second frequencies.

Abstract: 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.

Abstract: 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.

Abstract: A liquid crystal display includes first and second opposing spaced insulating substrates, pixel electrodes formed on the first substrate, a common electrode formed on at least one of the first and second substrates, and a liquid crystal layer interposed there between the first substrate and the second substrate. In this structure, each pixel electrode is divided into a main-pixel electrode and a sub-pixel electrode, to which different signal voltages are individually applied at the same gray scale. Further, a signal voltage to be applied to the sub-pixel electrodes is determined by a gamma value satisfying the following equation: Gamma K=(current gray scale/maximum gray scale)f F(Gray Scale)=a×(maximum gray scale/current gray scale), wherein a is a constant.
