  • Liquid crystal display and driving method thereof for adjusting refresh rate and luminance according to that of ambient light
    Patent number: 7742035
    Abstract: An exemplary liquid crystal display (200) includes a liquid crystal (LC) panel (210), a gate driving circuit (220) for scanning the liquid crystal panel, a data driving circuit (230) for providing a plurality of gradation voltages to the liquid crystal panel, an photo sensor (250) configured for measuring a frequency and a luminance of ambient light and generating a measurement signal, a timing control circuit (240) configured for controlling the gate driving circuit and the data driving circuit, and a backlight module driving circuit (270) for driving a light source (260) to emit light beams for illuminating the liquid crystal panel. One of the timing control circuit and the backlight module driving circuit is configured for receiving the measurement signal and adjusting a refresh rate and a luminance of the LC panel according to the frequency and the luminance of the ambient light.
