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