摘要:
A display apparatus includes a display panel that includes a plurality of pixels and a panel driver. The panel driver receives original image signals corresponding to successive frames which are displayed in a predetermined number within a predetermined period of time, forms an interpolation image signal on the basis of original image signals corresponding to two successive frames, and forms a non-image signal, and applies the original image signal, the interpolation image signal, and the non-image signal to the respective pixels during a display period.

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.

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.

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.

A wide variety of different alignment polar angles can be created in the alignment layers of a liquid crystal display with just a small number of UV exposure steps by using one or a combination of overlappable UV masks, where the one or more combinations of overlappable UV masks simultaneously define a maximal transmission region, an intermediate transmission region and a nontransmitting (blocking) region. UV rays are irradiated through masks in different irradiation directions while the mask or masks are disposed in different orientations.
