Claim:
A method for operating a memory cell array of a spatial light modulator of a display system, the memory cell array comprising a plurality of memory cells, the method comprising: grouping the memory cells in each row of the memory cell array into a set of subgroups according to a predefined criterion, each subgroup comprising at least one memory cell; connecting the memory cells to a plurality of wordlines such that memory cells in the same subgroup are connected to the same wordline, and memory cells in different subgroups are connected to separate wordlines; activating the memory cells in a first subgroup connected to a first wordline of a first row of the memory cell array; and activating the memory cells in a second subgroup connected to a second wordline of a second row of the memory cell array; wherein the memory cells of a first subgroup of the subgroups are connected to a first subset of the plurality of bitlines, and the memory cells of a second subgroup are connected to a second subset other than the first subset of the plurality of bitlines.
