Patent ID: 8299991

Claim:
A method of providing an LCD overdrive drive scheme, comprising: (i) measuring a stabilized transmission level of an LCD display pixel of an LCD device when a target drive level has resulted in the stabilized transmission level; (ii) measuring an overdrive transmission level of the display pixel at the end of a single frame after the application of an overdrive drive level; (iii) comparing the measured overdrive transmission level with the measured stabilized transmission level to determine if the overdrive drive level is too high or too low, wherein the initial overdrive drive level is determined to be too high if there is overshoot of the measured overdrive transmission level above a threshold which comprises the stabilized transmission level plus a predetermined amount; (iv) if the overdrive drive level is too high or too low, changing the overdrive drive level and repeating steps (ii) and (iii) until a suitable overdrive drive level is found; and (v) using the suitable overdrive drive level found to derive overdrive drive scheme parameters and storing the parameters in a memory of the LCD device.
