Redundancy assisted noise control for accumulated iterative compression error

A system for performing stress compensation in a display device, the system comprising:

• a memory;
• and
• a processing circuit comprising an adding circuit, the processing circuit being configured to perform:
• augmenting, by an adding circuit, a brightness value of an image displayed by the display device based on a previous decoded value to generate an accumulated brightness value;
• encoding the accumulated brightness value by selecting, for preservation in the memory, a protected portion of the accumulated brightness value, the protected portion comprising a plurality of bits from among bits of the accumulated brightness value;
• compressing the accumulated brightness value;
• storing the compressed accumulated brightness value in the memory;
• retrieving and decompressing the compressed accumulated brightness value to generate a decompressed value;
• decoding the decompressed value based on the protected portion to generate a decoded value corresponding to the accumulated brightness value, the decoded value having lower compression noise than the decompressed value;
• receiving, by the adding circuit, an output image to be displayed on the display device;
• and
• adding, by the adding circuit, the decoded value to a brightness value of the output image to generate an updated accumulated brightness value.
