Methods and apparatus to implement aging compensation for emissive displays with subpixel rendering

A non-transitory computer readable medium comprising instructions that, when executed, cause at least one processor to at least:

• convert red-green-blue (RGB) data to subpixel rendering (SPR) data, the RGB data indicative of an image to be rendered on an emissive display screen;
• apply pixel correction values to the SPR data to generate corrected SPR data to compensate for pixel degradation;
• sample the corrected SPR data to generate sampled corrected SPR data;
• update pixel usage data by adding additional pixel usage data indicated by the sampled corrected SPR data to stored pixel usage data;
• and
• calculate the pixel correction values based on the updated pixel usage data.

A system comprising:

• means for converting red-green-blue (RGB) data to subpixel rendering (SPR) data, the RGB data indicative of an image to be rendered on an emissive display screen;
• means for applying pixel correction values to the SPR data to generate corrected SPR data to compensate for pixel degradation;
• means for sampling the corrected SPR data to generate sampled corrected SPR data;
• means for updating pixel usage data by combining the sampled corrected SPR data with the pixel usage data;
• and
• means for calculating the pixel correction values based on the updated pixel usage data.

A method comprising:

• converting, via at least one logic circuit, red-green-blue (RGB) data to subpixel rendering (SPR) data, the RGB data indicative of an image to be rendered on an emissive display screen;
• applying, via the at least one logic circuit, pixel correction values to the SPR data to generate corrected SPR data to compensate for at least one of pixel degradation or subpixel degradation;
• sampling the corrected SPR data to generate sampled corrected SPR data;
• updating, via the at least one logic circuit, pixel usage data by adding additional pixel usage data indicated by the sampled corrected SPR data to previously stored pixel usage data;
• and
• calculating, via the at least one logic circuit, the pixel correction values based on the updated pixel usage data.
