摘要： A display apparatus includes a plurality of pixel regions. Each of the pixel regions includes a first sub-pixel region, a second sub-pixel region and a boost capacitor. The first sub-pixel region and the second sub-pixel region are electrically connected to the boost capacitor. The boost capacitor causes voltages the first and second sub-pixel regions to be at different voltages to increase the viewing angle of the display apparatus. One electrode of the boost capacitor, a coupling electrode, is formed over a storage capacitance line made of an opaque metal such that an additional boost capacitor (Cboost) may be formed without decreasing the aperture ratio of the pixel region. Other features are also provided.

摘要： A display apparatus includes pixels, a signal controller, a gray-scale voltage generator, and a data driver. The signal controller converts input image signals having a first frame frequency to first and second output image signals having a second frame frequency. The second output image signal is an interpolation between the input image signal for the present frame and an input image signal for a next frame after the present frame. The gray-scale voltage generator outputs a first gray-scale voltage group and a second gray-scale voltage group. The data driver converts the first output image signal to a first data voltage based on the first gray-scale voltage group and converts the second output image signal to a second data voltage based on the second gray-scale voltage group, and outputs the first and second data voltages to the pixels in a present frame.

摘要： In a display apparatus, a first display substrate includes a common electrode to which a common voltage is applied. A second display substrate facing the first display substrate includes a first pixel electrode and a second pixel electrode. The first and second pixel electrodes formed in one pixel region are spaced apart from and insulated from each other. A first data voltage having a first polarity with reference to the common voltage is applied to the first pixel electrode, and a second data voltage having a second polarity different from the first polarity with reference to the common voltage is applied to the second pixel electrode. Thus, a fringe field is formed between the first and second display substrates and a lateral field is formed in the second display substrate, thereby improving a transmittance and a response speed of the display apparatus.

摘要： A liquid crystal display panel includes a pixel having a switching element electrically connected to a gate wiring and a source wiring and a liquid crystal capacitor electrically connected to the switching element. A timing controller receives a mode selecting signal corresponding to an impulsive driving mode, and outputs a first common voltage corresponding to the impulsive driving mode. A common voltage converter converts the first common voltage into a second common voltage of analog type, and outputs the second common voltage to the liquid crystal capacitor. Therefore, in the LCD apparatus operated in an impulsive driving method, a common voltage is selectively applied to the liquid crystal display panel, thus improving a display quality.

摘要： A liquid crystal display (LCD) with a direction control electrode and a pixel electrode forming a capacitance in a pixel regions is disclosed. Gate lines are formed on the first substrate and extending in the first direction. Data lines are intersecting the gate lines and each data line has a bent shape. Pixel regions are defined by the intersecting of the gate lines and the data lines. The direction control electrode is formed at the corresponding pixel region and electrically connected to the corresponding data line. The pixel electrode is formed at the corresponding pixel region and has a shape conformal to the corresponding pixel region. By adjusting the capacitance between the direction control electrode and the pixel electrode, liquid crystal stability is enhanced.
