1. A current-biased, voltage-programmed display panel allowing measurement of temperature, comprising: a plurality of pixels each including a drive transistor and an organic light emitting device coupled to the drive transistor; and a controller coupled to each of the plurality of pixels, the controller causing a programming voltage to be applied to the gate of the respective drive transistors to control the brightness of each pixel, the controller further reading data from selected ones of the plurality of pixels to determine the temperature of the selected ones of the plurality of pixels, the controller estimating the temperature of the other non-selected plurality of pixels based on the determined temperature of the selected ones of the plurality of pixels.
