16‐3: A Fast TFT Threshold Voltage Sensing Method Based on Iterative Feedback

In this paper, we present a fast TFT threshold voltage extraction method adapting iterative feedback. Using this method we can obtain relative TFT threshold voltage Vth of all pixels in the AMOLED display. According the relative TFT threshold voltage, we can compensate the driving data to significan...

Zusammenfassung:In this paper, we present a fast TFT threshold voltage extraction method adapting iterative feedback. Using this method we can obtain relative TFT threshold voltage Vth of all pixels in the AMOLED display. According the relative TFT threshold voltage, we can compensate the driving data to significantly improve the uniformity of AMOLED display.
