Classification: CPC G | IPC G

Claim 0:
1. A display device comprising:
a display panel including pixels; and
a display panel driver configured to drive the display panel,
wherein the display panel driver is configured to determine a predicted on-pixel ratio of a current frame based on an artificial neural network model and input image data of a previous frame, to determine a first adjustment value based on the predicted on-pixel ratio, and to adjust a luminance of the current frame based on the first adjustment value,
wherein the predicted on-pixel ratio is a ratio of a driving amount when the pixels are driven based on input image data of the current frame to a maximum driving amount when all of the pixels are driven based on a maximum grayscale value,
wherein the artificial neural network model is configured to determine the predicted on-pixel ratio as probabilities for on-pixel ratios,
wherein the display panel driver is configured to determine the first adjustment value by summing values generated by multiplying the probabilities of on-pixel ratios and predetermined reference adjustment values corresponding to the on-pixel ratios, respectively.
