1. A luminance circuit comprising:
a one-time programmable non-volatile memory array comprising:
a luminance data memory configured to store luminance data of a display device, and
a redundant memory configured to store error correction data to correct an error of the luminance data;
a luminance adjust circuit configured to receive image data to be displayed on the display device;
a memory control circuit coupled to the one-time programmable non-volatile memory array and configured to control operations of the one-time programmable non-volatile memory array; and
an input/output interface coupled to the memory control circuit and configured to receive the luminance data from outside of the luminance circuit;
wherein the luminance adjust circuit is coupled directly to the one-time programmable non-volatile memory array to obtain the luminance data of the display device and the error correction data from the one-time programmable non-volatile memory array and adjust the image data based on the luminance data of the display device and the error correction data, wherein the memory control circuit and the input/output interface are embedded in the luminance adjust circuit.
