Patent ID: 8064118

Claim:
A display system receiving an image signal containing a binary data of N bits, wherein N is a positive integer, for displaying an image with a grayscale corresponding to said binary data, comprising: a spatial light modulator (SLM); and a data converter for converting M-bit of said binary data of N-bits for all of said plurality of pixel elements into a non-binary data, wherein M is a positive integer and N≧M≧2, for applying said non-binary data as a sub-frame data in controlling said gray scale for all of said plurality of pixel elements in displaying said image; and said data converter further carrying out a data conversion process including steps of: a) calculating a first segment of non-binary data from M-bit binary data corresponding to a first pixel element of the spatial light modulator and transferring the data to the spatial light modulator, b) calculating first segment data corresponding to all pixels sequentially and transferring the data to the spatial light modulator (SLM); c) further calculating second segment data corresponding to all pixels sequentially and transferring the data to the spatial light modulator; d) calculating and transferring all segmented data repeatedly until the entirety of M-bit binary data is converted into non-binary data and the data is transferred to the spatial light modulator.
