Abstract: A present invention field emission display brightness compensation system and method is capable of providing uniform display correction. In one present compensation system and method a masking process is utilized that adjusts the emissions for a particular area (330, 350, 370, 390). In one exemplary implementation, the relative value of a pixel driver voltage is adjusted to correspond to a base brightness area. For example, an emitter uniformity area adjustment table is utilized to adjust the voltage value of the emitters. In emitter uniformity area adjustment table provides a correlation between a pixel location and a brightness level adjustment. The emitter uniformity area adjustment tables are utilized to create a software filtering mask that provides compensation for uniformity differences between different spots or areas in the display.
