LIQUID CRYSTAL DISPLAY, DEVICE AND METHOD FOR DRIVING LIQUID CRYSTAL DISPLAY

摘要

PROBLEM TO BE SOLVED: To improve the performance of a liquid crystal display by reducing EMI of the liquid crystal display while reducing the manufacturing cost. SOLUTION: The liquid crystal display is connected to a gate line and a data line respectively and includes a liquid crystal display plate assembly having a plurality of pixels arranged in a matrix form. The liquid crystal display plate assembly is provided with a gate driving section which transmits signals to the gate line and a data driving section which transmits signals to the data line. A gradation voltage generating section which generates a plurality of gamma voltages includes a D/A converter for converting the digital gamma voltage from a signal control section into analog gamma voltage. A plurality of data driving circuits select the gradation voltage corresponding to picture data out of a plurality of gamma voltages and apply it to the pixel as data voltage. The signal control section applies the picture data to the data driving circuit through wiring independently connected to each data driving circuit, generates control signals for controlling the picture data and applies them to the data driving section.
