Abstract
A method of operating a display includes operating a pixel of the display using a first signal to provide a first brightness level. A characteristic of the first signal is represented by a value in a range extending from a minimum signal value to a maximum signal value. A second brightness level is then selected and is different from the first brightness level. A truncated table is consulted and contains 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, where 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. An overdrive signal is determined from the overdrive values of the truncated table based on the first and second brightness levels. The pixel is briefly operated using the overdrive signal to facilitate transition to the second brightness level. The pixel is then operated using a second signal corresponding to the second brightness level.
