Abstract:
1. A method of operating a display, the method comprising: operating a pixel of the display using a first signal to provide a first brightness level, wherein a characteristic of the first signal is represented by a first value, S selecting a second brightness level, different from the first brightness level, wherein the second brightness level corresponds to operating the pixel using a second signal, wherein a characteristic of the second signal is represented by a second value, S consulting a truncated table which comprises overdrive values for selected pairs of possible first and second brightness levels, the overdrive values are in a range extending from a minimum table value to a maximum table value, wherein the minimum table value is less than the minimum signal value or the maximum table value is greater than the maximum signal value or both; determining an overdrive signal, and corresponding overdrive value, S operating the pixel using the overdrive signal to facilitate transition to the second brightness level; and operating the pixel using the second signal corresponding to the second brightness level after operating the pixel using the overdrive signal.
