Patent abstract
A display apparatus includes a display panel including a light-emitting device; a storage storing a target gamma value and a calibration matrix; a processor configured to obtain first modulation data from input data and calibrate the first modulation data via the calibration matrix, obtain second modulation data from the calibrated first modulation data, and generate a driving signal from the second modulation data; and a panel driver configured to drive the display panel by applying the driving signal to the light-emitting device, wherein the calibration matrix has a compensation coefficient for making a gamma curve corresponding to the driving signal to be the same as a target gamma curve corresponding to the target gamma value.
