Claim 10:
11. An optical compensation method, comprising:
measuring optical characteristics of a display panel through a measuring device and generating measurement result data of the optical characteristics;
executing an artificial intelligence process based on an artificial intelligence neural network using previous optical compensation result data for at least one other display panel;
predicting and generating a data voltage for each band or gradation as optical compensation result data corresponding to the measurement result data of the optical characteristics according to a result of executing the artificial intelligence process; and
storing information on the predicted and generated data voltage in a memory corresponding to the display panel,
further comprising a loop controlling operation of changing a band and a point after the operation of predicting and generating the data voltage,
wherein after the loop controlling operation, the operation of generating the measurement result data of the optical characteristics, the operation of executing the artificial intelligence process, and the operation of predicting and generating the data voltage are repeatedly executed.
