1. An optical compensation system, comprising:
a measuring device configured to measure optical characteristics of a display panel and output measurement result data of the optical characteristics; and
an artificial intelligence-based optical compensation controller configured to predict and generate optical compensation result data corresponding to the measurement result data of the optical characteristics based on an artificial intelligence neural network using previous optical compensation result data for at least one other display panel, the artificial intelligence-based optical compensation controller configured to store the predicted and generated optical compensation result data in a memory corresponding to the display panel,
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.
