In Active Matrix Organic Light Emitting Diode (AMOLED) Display. TFTs are used as driving transistors for OLED. Because of the non uniformity of the TFTs, variation in threshold voltage and mobility has a negative effect in performance of the OLED. During this thesis we investigated two types of driving scheme, Voltage and current programmable pixels, with Single grain Si TFT. New structure of pixel is purposed with array of photodiodes beneath Cathode/Anode layer of OLED which is used for giving optical feedback to the driving TFT. With this structure, possibility of compensation for the threshold voltage variation is investigated.
