Abstract
A real-time external sensing and compensation method for active matrix organic light emitting diode displays is proposed. The proposed method senses and compensates for the variation of electrical characteristics of poly-Si thin-film transistors (TFTs) during display time. Experimental results show that the proposed method successfully senses the electrical characteristics of TFTs in real-time and compensates for the non-uniform emission current error.
