Patent ID: 8405598

Claim:
An overdrive method of a liquid crystal display (LCD), comprising: using temperature-information-acquiring means to acquire temperature data near LCD elements which are arranged as a matrix; storing data-inputted target level values of an entire frame in a first frame memory; acquiring an overdrive value corresponding to the temperature data from a first data table established depending on temperature according to a combination of one of the target level values and a first predicted level value, wherein a maximum value in a driving voltage range from a black level voltage to a white level voltage is set as a maximal available overdrive value before a voltage corresponding to the initial level value reaches a predetermined level, and a voltage beyond the driving voltage range from the black level voltage to the white level voltage is set as the maximal available overdrive value when the voltage corresponding to the initial level value exceeds the predetermined level; acquiring a second predicted level value after a predetermined frame number corresponding to the temperature data from a second data table established depending on temperature according to a combination of the one of the target level values and the first predicted level value; storing the second predicted level values of an entire frame in a second frame memory; repetitively providing the same target level value from the first frame memory to the first data table and the second data table, and repetitively providing the same second predicted level value from the second frame memory to the first data table and the second data table as the first predicted level value, while accumulating a counted number of data input until the counted number reaches the predetermined frame number; and applying a driving voltage to a corresponding one of the LCD elements according to the overdrive value.
