Abstract
The present invention discloses a liquid crystal display driving system that uses at least one temperature sensor to detect a temperature of a LCD panel, and outputs a gamma compensation voltage value according to the detected temperature, and further uses an overdrive compensation unit to receive the gamma compensation voltage value, and obtains the overdrive compensation voltage value of two gamma overdrive compensation curves of a temperature gradient corresponding to a region of the LCD panel by a gamma mapping method, or uses an overdrive compensation unit to derive a corresponding partial compensation data table according to the temperature and the compensation data table, and at least one overdrive compensation table (OD compensation table) corresponding to the change of temperature gradient in a region of the LCD panel is derived, an outputted display image after being processed by an overdrive lookup table (OD LUT) is compensated, so as to adjust the overdrive voltage of the LCD panel and enhance the response time of the liquid crystal display.
