    摘要: The present invention relates to a line inversion type liquid crystal display and a driving method thereof. A plurality of pixels arranged in a matrix, a plurality of data lines extending in a row direction and a plurality of gate lines extending in a column direction are disposed in a liquid crystal panel of the liquid crystal display. The pixel has a liquid crystal capacitor for performing display operation and a switching element turned on in response to a gate-on voltage to apply a data signal to the liquid crystal capacitor. A gate driver sequentially provides gate-on pulses to the gate lines based on gate control signals from a timing controller, and a data driver sequentially applies the data signals with polarity inversion, corresponding to color signals from the timing controller based on the data control signal from the timing controller. The polarity of the data signals is inverted by the unit of at least two pixel rows. Since the width of the gate-on pulse applied to the first pixel row with polarity inversion is larger than that of other gate-on pulses, a charging ratio of the first pixel row with polarity inversion is larger than that of the other rows.

    摘要: A liquid crystal display includes a liquid crystal display panel for displaying picture images, and a color correction unit. Upon receipt of raw RGB picture data corresponding to raw RGB gamma curves, the color correction unit generates corrected RGB picture data based on values over a predetermined imaginative gamma curve established in accordance with the characteristic of the liquid crystal display panel. The color correction unit stores values over corrected RGB gamma curves corresponding to the corrected picture data, and gamma-corrects the raw RGB picture data based on values over the stored corrected RGB gamma curves, thereby displaying the picture images.

    摘要: Disclosed are an LCD capable of realizing a pre-charging method even in the random data-enable mode, and an apparatus and method for driving the same. In the LCD driving apparatus, a timing controller outputs a vertical sync start signal based on a data-enable signal having an irregular output interval to control the output of the image data. A gate driver sequentially applies both first and second gate-on voltages to a same gate line based on the vertical sync start signal. The first gate-on voltage is to drive a previous line being most adjacent to and having the same polarity as the current line, and the second gate-on voltage is to drive the current line. An LCD panel is first charged with the first gate-on voltage supplied from the gate driver, and then charged with the second gate-on voltage, so that it can display analog image data received from the data driver during the second charging.

    摘要: A method and device for improving image quality without the attendant cost-increasing factors such as a high number of frame memories and high power consumption is presented. In one aspect, the invention is a signal processing device for a display unit that includes a signal processor and a frame memory. The signal processor receives image data in a first format and generates a modified image data in a second format that has a different bit number and frequency than the first format. The signal processing device may include a signal processor, a data output unit, and a frame memory (e.g., DDR memory). The signal processor receives image data having a given data rate and divides the image data into two sets of image data. The data output unit receives the sets of image data and generates a recombined image data having a higher data rate.
