Classification: CPC G | IPC G

Claim 7:
8. A display device, comprising:
a buffer configured to store compressed stress data;
a decoding circuit configured to receive the compressed stress data for a slice of a display, and to decompress the compressed stress data to obtain reconstructed stress data for the slice of the display;
an adding circuit configured to add additional stress data to the reconstructed stress data to obtain updated stress data for the slice;
an encoding circuit configured to encode the updated stress data at a first precision level (pc) to generate first updated compressed stress data for the slice of the display; and
a processor configured to, in response to a size (bc) of the first updated compressed stress data for the slice of the display exceeding a size (bt) of the buffer, determine a second precision level (p) by performing a calculation using the first precision level (pc), a third precision level (ps) of the additional stress data, and a fourth precision level (pb) of the buffer,
wherein the encoding circuit is further configured to encode the updated stress data at the second precision level (p) to generate second updated compressed stress data that is different than the first updated compressed stress data,
wherein the third precision level (ps) of the additional stress data corresponds to a level of precision at which the additional stress data increases a size of the updated stress data, and
wherein the fourth precision level (pb) of the buffer corresponds to a level of precision at which the buffer increases a size of the first updated compressed stress data.
