Abstract
A graphical display device includes a plurality of color-specific subpixels spatially distributed across a display region. Subpixel wear compensation is performed for some or all of the color-specific subpixels. For each color-specific subpixel, the compensation may include sampling one or more display signals directed to the color-specific subpixel to obtain a time-series of sampled values. The compensation may further include storing, in non-volatile storage, compensation data for the color-specific subpixel derived from the time-series of sampled values. The compensation may further include driving the color-specific subpixel based on the compensation data.
