Title: Spatial-temporal multiplexing for high bit-depth resolution displays

Abstract: A method and apparatus for spatially and temporally multiplexing display data. The use of this method results in a bit-depth resolution higher than that achievable by the system given a number of bits of resolution. The method includes the steps of determining the desired perceived resolution (26), establishing the number of bit-planes to be used to achieve that perceived resolution (28), using at least one of those bit-planes for spatial-temporal least significant bit values (STMLSBs) (30), referencing the developed values of the STMLSBs to fractional bit gray code levels (32), developing spatial patterns (34), determining whether the spatial patterns will start in a predetermined sequence or randomly from frame-to-frame (36), loading the data onto the modulator and displaying it (38). The apparatus includes a random number generator (48) and a look up table (50) to enable the choice between random and predetermined spatial patterns, and pattern logic (46), which produces the pattern to be used.
