Abstract:
Disclosed is a circuit and technique to determine the temperature of an AMOLED display in order to calibrate programming data signals. The temperature of selected pixels of a plurality of pixels in an AMOLED display is measured via one of several disclosed methods. A thermal sensor for the selected pixels may be used. A measurement of output voltage data may be used to estimate temperature. A finite element analysis model may be used based on consumed power of the selected pixel. The temperature data for the selected pixel is then interpolated to the neighboring non-selected pixels to estimate the temperature of those pixels.
