Abstract
A method is provided for utilizing an M by N matrix array of electro-optic display elements that uses multi-row addressing, the method reducing row artifacts owing to adjacent row cross-talk and improving display performance. The method permits the use of a display device with large pixel count, yet with high display definition and performance.
Claims15
A method of addressing an array of M row by N column display elements comprising:
- (a) delivering a plurality of (Q+1) enabling switching signals to a plurality of (Q+1) rows of elements through electrical connections, wherein Q is a whole number 2 or greater, wherein the (Q+1)th row is contiguous to the Qth row;
- and
- (b) delivering independent signals to each enabled element, except those elements in the (Q+1)th row, which row receives a pre-write signal, the signals modulating light in the enabled display elements;
- wherein there is a reduction of artifact brightness in the Qth, 2*Qth and 3*Qth ones of the M rows.
