Abstract: A present invention field emission display brightness compensation system and method is capable of providing uniform display correction. In onepresent compensation system and method a masking process is utilized thatadjusts the emissions for a particular area. In one exemplary implementation,the relative value of a pixel driver voltage is adjusted to correspond to a basebrightness area. For example, an emitter uniformity area adjustment table is utilized to adjust the voltage value of the emitters. An emitter uniformity areaadjustment table provides a correlation between a pixel location and a brightnesslevel adjustment. The emitter uniformity area adjustment tables are utilized tocreate a software filtering mask that provides compensation for uniformitydifferences between different spots or areas in the display.
