Patent ID: 8816942

Claim:
A light emitting display including pixel cells arranged in rows and columns, wherein each pixel cell includes a light emitting means and a current control means connected in series, which current control means controls a current through the light emitting means, wherein each pixel cell further includes a first switch, which connects a control terminal of the current control means to a first data line, for programming a current, wherein each pixel cell further includes a second switch, which DC-connects a current conducting terminal of the current control means, via a second data line, to a means for measuring a current through the current control means, wherein the first switch of a first pixel cell in a second row and the second switch of a second pixel cell in a first row are connected to a common control line, such that, in response to a corresponding common control signal, the first pixel cell in the second row is connected for programming while, at the same time, the second pixel cell in the first row is connected for measuring.
