ABSTRACT:
A method is provided for compensating for output nonuniformity on a display. The method comprises characterizing the display. The method further includes creating a set of data tables wherein one table provides data for compensation along vertical axes of the display and a second table provided data for compensation along horizontal axes of the display, and wherein components of the tables include a linear offset factor to correct data for nonuniformity and a slope factor which permits gray scale information to be recovered at points near the limits of the gray scale range. The characterizing step may include using a optical detector to obtain optical output information from the display. The slope factor may be calculated to preserve top end gray scale range of the display by adjusting luminous output so that input data level maps to separate output grey levels between a truncated and an untruncated level.
