Classification: CPC G | IPC G

Claim 14:
15. A display device, comprising:
a display panel including a data line;
a memory configured to store information on a data voltage for each band or gradation; and
a data driving circuit configured to output a data voltage corresponding to a current band or a current gradation among the data voltages for each band or gradation to the data line,
wherein the information on the data voltage for each band or gradation stored in the memory is information predicted and generated as optical compensation result data corresponding to measurement result data of optical characteristics of the display panel according to a result of executing an artificial intelligence process based on an artificial intelligence neural network,
wherein the artificial intelligence neural network is an affine layer neural network,
wherein the affine layer neural network includes an input layer including a plurality of input nodes corresponding to processing information of a first preprocessing, a first intermediate layer including a plurality of first intermediate nodes corresponding to processing information of a second preprocessing, a second intermediate layer including a plurality of second intermediate nodes corresponding to processing information of a third preprocessing, and an output layer including a plurality of output nodes corresponding to processing information of a main processing,
wherein the first preprocessing is a pre-optical compensation processing for each color coordinate or luminance, the second preprocessing is a pre-optical compensation processing for each color using a first luminance value, the third preprocessing is a pre-optical compensation processing for each color using a second luminance value higher than the first luminance value, and the main processing is a processing for obtaining the measurement result data of the optical characteristics.
