System and method for improving the operating characteristics of a display

Abstract

The present invention provides a display system and driving method, such as a liquid crystal display on a silicon display, that reduces phase ripple, phase switching noise, and phase instability, and improves other operating characteristics. [Solution] A driving scheme is used that has an optimal number and distribution of on / off bits for each gray / phase level. The sequence of binary values ​​used to achieve a desired gray or phase value within a frame or subframe is optimized by scattering a desired number of on values ​​for that gray or phase value within that frame or subframe, such that the on periods occur at substantially equal intervals throughout the duration of the frame or subframe, within that frame or subframe where the off values ​​are located.

Claims

[Claim 1] A display system comprising a display and a display driver, The display driver is configured to send a bit plane to the display according to a display table, Each row of the display table includes a sequence of bit planes associated with one of a plurality of phase values, Each sequence of the bit plane includes several 1 values ​​and several 0 values ​​associated with each of the plurality of phase values, For each sequence of a bit plane where the number of single values ​​is greater than 1, the number of single values ​​is distributed over the entire length of the bit plane sequence such that one or more groups of one or more single values ​​are separated from one or more groups of one or more zero values. A display system in which each of the one or more groups of one or more single values ​​has approximately the same number of bit planes, and each of the one or more groups of one or more zero values ​​has approximately the same number of bit planes.
