Method and system for compressing Demura compensation value

A system for compressing Demura compensation value, comprising:

• a data acquiring circuit, configured to acquire original compensation values of a target panel;
• a spatial sampling circuit, configured to input the original compensation values into a spatial domain sampling model and perform a down-sampling to obtain spatial domain sampling values;
• a prediction mode circuit, configured to input the original compensation values into a prediction mode overall model and perform a numerical processing to obtain a plurality of mode characteristic values;
• a data reconstructing circuit, configured to perform 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;
• a syntactic element coding circuit, configured to perform a syntactic encoding on the spatial sampling values and the plurality of mode characteristic values to obtain a syntactic element code set;
• an optimal prediction mode selecting circuit, configured to perform a mode selection according to the reconstructed value set and the syntactic element code set to obtain an optimal prediction mode;
• and
• a compensation value compression code outputting circuit, configured to acquire and output a syntactic element code corresponding to the optimal prediction mode to obtain a Demura compensation value compression code.
