First Claim
Patent Images
1. A display apparatus, comprising:
- control means for controlling the display of pixels constituting a screen display based on input data;
a correction memory storing correction data for eliminating unevenness in brightness among respective pixels; and
correcting means for correcting brightness irregularities based on the data stored in the memory and the input data, wherein the correction data stored in the correction memory are entropy coded data, andthe correcting means being configured to expand the entropy coded data and calculate correction values based on expanded data and the input data.

Abstract
After a look-up table applies y correction to each of R, G, and B signals, a multiplier multiplies a y corrected signal by a gain. An adder adds an offset to an output of the multiplier and supplies a resultant gain/offset corrected signal to a display panel. Memories store entropy coded correction data, which can be expanded by corresponding expansion circuits and supplied to the multiplier and the adder, respectively.
