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.

In a display apparatus and a method of driving the same, an active period during which one pixel is turned on is divided into a red sub frame, a green sub frame, a blue sub frame, and a white sub frame. A controller compares a gray scale of a fourth image data corresponding to the white sub frame with a reference gray scale and compensates a first image data, a second image data, and a third image data corresponding to the red, green, and blue sub frames, respectively, in accordance with the comparison result.

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.

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:
A display substrate includes a base substrate, a reflection-polarization member, a first electrode, an insulation layer and a pixel wall. The reflection-polarization member is disposed on the base substrate to reflect and polarize incident light. The first electrode is disposed in a unit pixel area of the reflection-polarization member. The insulation layer is disposed on the first electrode. The pixel wall is disposed on the insulation layer and defines the unit pixel area. Therefore, the entire area of a unit pixel may be used as a reflective area or a transmissive area, and thus an aperture ratio may be improved in a reflection mode or a transmission mode.
