Patent ID: 7995002

Claim:
A tiled, passive-matrix, EL display, including: a) two or more EL tiles, each EL tile including an array of rows and columns of light-emitting elements, each light-emitting element being formed from a light-emitting layer that is sandwiched between an orthogonal array of row and column electrodes wherein each of the two or more EL tiles further include at least one row driver; b) at least one column driver for operating in conjunction with each of the at least one row drivers to control the flow of electrons between the row and column electrodes to control the emission of light from each of the light-emitting elements; and c) one or more controllers coupled to the row drivers and column driver(s) for receiving an input image signal and for simultaneously providing row drive signals to the two or more drivers within the two or more EL tiles to control the flow of electrons through the row and column electrodes to simultaneously illuminate a group of a predetermined number of rows of light-emitting elements within each EL tile during a time interval, wherein in each EL tile, the groups of illuminated rows of light-emitting elements in two subsequent time intervals are selected with no overlap with a first exception that when the boundary between the two tiles is to be illuminated, then the number of illuminated rows of light-emitting elements in the present group is less than the predetermined number, and the present group of illuminated rows of light-emitting elements overlaps the previous group of illuminated rows of light-emitting elements.
