摘要： A liquid crystal display with improved color reproducibility and image quality is presented. The liquid crystal display includes a liquid crystal panel assembly including a plurality of pixels, a signal controller, and a data driver. The signal controller stores a dithering data patterns, selects one of the dithering data patterns based on input image data having a first bit number, and converts the input image data to output image data having a different bit number using the selected dithering data pattern. The data driver applies data voltages to the pixels, the data voltages corresponding to the output image data from the signal controller. Frequency of the input image signal and the output image signal from the signal controller is each about 120 Hz, and the dithering data patterns are repeated every eight frames. The signal controller includes a look-up table that stores the dithering data patterns.

摘要： A gate drive portion for a display device including multiple pixels having first and second sub-pixels includes a first shift register generating a first output signal in response to a first gate clock signal, a second shift register generating a second output signal in response to a second gate clock signal, a level shifter coupled to the first and second shift registers and amplifying the first and second output signals, and an output buffer coupled to the level shifter and generating first and second gate signals. The first gate signal is generated in synchronization with the first gate clock signal and the second gate signal is generated in synchronization with the second gate clock signal. Accordingly, the charging time of the first and second sub-pixels may be improved by separately driving the odd-numbered and even-numbered sub-pixels and the visibility of the LCD device may also be improved.

The liquid crystal display device includes first and second main PCBs for driving a dual bank type liquid crystal panel, the first main PCB having a timing controller for processing external odd input signals to generate driving signals, and sending part of the driving signals to a corresponding source driver PCB, so as to generate video signals to be supplied to the odd pixels of the liquid crystal panel; and the second main PCB having a timing controller for processing external even input signals to generate driving signals, and sending part of the driving signals to a corresponding source driver PCB, so as to generate video signals to be supplied to the even pixels of the liquid crystal panel. According to the present invention, two source driver PCBs are used to supply video data to the upper part and the lower part of the liquid crystal panel, respectively, and thereby to reduce signal delay and distortion in driving the dual bank type liquid crystal display device for a large screen with high resolution, thus solving the problems of coupling between signals more deviating from the tolerance range with an increased frequency, noise, and EMI.
