Claim 0:
1. A method for compensating for transistor aging in a display device, comprising:
identifying Z pixels from among a plurality of pixels that are included in a first group of a plurality of groups, wherein Z>1;
sensing, for each pixel in a subset of pixels in the first group, a pixel current output to the pixel, the subset including M pixels, wherein 1≤M≤Z;
determining an ErrorM using the sensed pixel current for the M pixels and a predefined reference current; and
adjusting, for each pixel of the Z pixels, an input voltage for a transistor of the pixel using the ErrorM,
wherein ErrorM=ΣMsign(ErrorM), m being one pixel of the M pixels, and Errorm being an error of the one pixel based on the sensed pixel current of the one pixel and the reference current.
