1. A method for compressing Demura compensation value, comprising:
acquiring original compensation values of a target panel;
inputting the original compensation values into a spatial domain sampling model, performing a down-sampling to obtain spatial domain sampling values, inputting the original compensation values into a prediction mode overall model, and performing a numerical processing to obtain a plurality of mode characteristic values;
performing a data reconstruction on the spatial sampling values and the plurality of mode characteristic values to obtain a reconstructed value set after the data reconstruction;
performing a syntactic encoding on the spatial sampling values and the plurality of mode characteristic values to obtain a syntactic element code set;
performing a mode selection according to the reconstructed value set and the syntactic element code set to obtain an optimal prediction mode; and
acquiring and outputting a syntactic element code corresponding to the optimal prediction mode to obtain a Demura compensation value compression code.
