Abstract:
A method of delayed addressing of a matrix of display elements configured in N rows and M columns where the matrix is to be addressed as Ne effective lines, where Ne<N, the method comprising, for each display cycle, the steps of:a) storing in a first frame buffer an on or off status of each of the display elements for a first frame;b) partitioning each of the N rows which are identical to a first pattern into a first group;c) selecting subsequent patterns and partitioning each row, of the N rows, with identical subsequent patterns into corresponding subsequent groups in which each group contains each row, of the N rows, having a corresponding pattern;d) determining a total number of groups, Ng, of the groups partitioned in steps b) and c), that have more than one row corresponding to one of the unique patterns;e) determining a number of rows Ni in the Ng groups;f) driving the Ni rows in Ng cycles;g) determining a number of partitions, Np, of Nrpp rows each, that are driven in parallel, where Nrpp>1 and Np is given by: ##EQU2## h) determining Nrpp.multidot.Np rows from rows not in the Ng groups whose grouping results in substantially the smallest error;i) driving the Nrpp.multidot.Np rows determined in step h) as Np partitions, of Nrpp rows each, in Np cycles; andj) driving Ns=N-Ni-Nrpp.multidot.Np rows not driven in steps f) and i) as Ns effective lines in Ns cycles, wherein each of the Ns rows are driven individually.
