Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 6:
7. A display device comprising:
a plurality of pixels arranged in rows and columns, each of the pixels including a transistor; and
a sensing front end circuitry that is configured to sense, for each pixel of a subset of M pixels out of Z pixels in a group, a pixel current output to the pixel, wherein 1≤M≤Z, and adjust, for each pixel of the Z pixels, an input voltage to be supplied to the transistor of the pixel using 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 a reference current.
