Classification: CPC G | IPC G

Claim 8:
9. The display device of claim 3, wherein the compensation grayscale calculator is configured to calculate the compensation grayscale data which include a compensation grayscale value for the measured grayscale by Mathematical formulas 1, 2 and 3 below:

LRM=α*LRC  Mathematical formula 1

γM=β*γC  Mathematical formula 2

GC=GI/(LRC*α)1/(γC*β))−GI  Mathematical formula 3

where LRM is a measured luminance ratio included in measured luminance ratio data,
LRC is a captured luminance ratio included in captured luminance ratio data,
γM is a measured gamma included in measured gamma data,
γC is a captured gamma included in captured gamma data,
GC is a compensation grayscale value included in compensation grayscale data, and
GI is an input grayscale value included in input grayscale data.
