  • Patent number: 9805686
    Abstract: A display device is disclosed. The display device includes: a plurality of pixels; a memory storing a lookup table including compensation values for pixels at specific locations of the display. The lookup table also stores compensation values obtained by a bilinear compensation method. The display also includes a data compensator calculating the compensation values corresponding to a location where an image signal is displayed using the compensation values and substitution values stored in the lookup table. The substitution values are obtained by bit-shifting the compensation values acquired by bilinear compensation method. The display device avoids the need to use large and slow divider circuits used in ICs implementing bilinear compensation method.
