Abstract:
1. A circuit for overdriving an LCD panel according to an image data and a temperature, comprising: a memory for storing a previous image data; a plurality of look up tables (LUTs), each coupled to receive the previous image data from the memory and a present image data, for storing overdrive values; a first temperature sensor, for sensing the temperature of a first area of the LCD panel to generate a first temperature data; a control circuit, coupled to the first temperature sensor, for generating a selection signal and a temperature correction coefficient according to the first temperature data; a selection circuit, coupled to the plurality of LUTs, for selecting one LUT from the plurality of LUTs according to the selection signal and outputting the overdrive value of the selected LUT; and an overdrive processor, coupled to the selection circuit and the control circuit, for generating adjusted image data according to the overdrive value and the temperature correction coefficient.
