摘要:
An exemplary liquid crystal display includes a frame buffer (41), a frame rate conversion circuit (42), a data divider (43), and a data driver (44). The frame buffer is configured for doubling a frame rate of inputted signals. The frame rate conversion circuit is configured for reducing a bit number of signals. The frame rate conversion circuit includes a first and a second look up table. The first look up table converts a gray level of one of the sub-frames into a higher gray level corresponding to signals with the lower bit number. The second look up table is configured for converting a gray level of the other sub-frame into a lower gray level corresponding to signals with the lower bit number. The data divider is configured for transmitting the signals to the data driver in several buses. The data driver drives the liquid crystal display to display images.

An exemplary method for driving a typical liquid crystal display (2) with a matrix of pixels (205) includes the steps of: (a) applying video signals with a first polarity pattern to the pixels during a frame period, (b) re-defining the first polarity pattern by sequentially shifting the polarity sequences of one row to an adjacent row within a 2K-by-2K square sub-matrix of the pixels; (c) applying video signals with the re-defined first polarity pattern to the matrix of pixels during next frame period; and (d) repeating steps (b) and (c).

An image display system and method. A pixel of the system has a latch circuit and a display circuit. According to a scan line signal, the latch circuit receives and temporarily stores a data line signal. The display circuit works according to a reset signal and a set signal. According to the reset signal, the display circuit resets a voltage level of a control terminal of liquid crystal materials of the pixel. According to the set signal, the display circuit receives the data line signal stored in the latch circuit, to adjust the control terminal of the liquid crystal materials and thereby the liquid crystal materials are rotated and the expected image of the pixel is displayed accordingly. The active interval of the reset signal is arranged after a last scan line signal is disabled and prior to the enabling of the set signal.

A display driving unit used in a liquid crystal display (LCD) stores two γ curves. When the LCD displays images, the display driving unit determines the luminance of the image in a first sub-period for displaying the image according to the gray level of the image and the first γ curve, and determines the luminance of the image in a second sub-period for displaying the image according to the gray level of the image and the second γ curve. The LCD displays the image in the luminance determined according to the gray level of the image and the first γ curve in the first sub-period and displays the image in the luminance determined according to the gray level of the image and the second γ curve in the second sub-period.
