Abstract
A flat panel display (300) having a spacer (351) situated between a faceplate structure (320) and a backplate structure (330) is partitioned into (a) a pair of spacer-adjacent regions (303 and 304) adjacent to, and on opposite sides of, the spacer and (b) a pair of spacer-charging regions (302 and 305) respectively adjacent to, and further away from the spacer than, the spacer-charging regions. Each of the spacer-adjacent and spacer-charging consists of one or more pixel rows. Instead of activating the pixel rows sequentially during a frame of pixel information, the pixel rows are activated according to the order that arises when both of the spacer-charging regions are activated after activating the two spacer-adjacent regions. Operating the display in this manner reduces charge buildup on the spacer.
