This study presents a novel voltage-modulated pixel circuit for active-matrix organic light-emitting diode (AMOLED) consisting of five n-type thin-film transistors (TFTs), one additional control signal, and one storage capacitor. The proposed circuit, which can be implemented in all-n-type and all-p-type low temperature poly-silicon (LTPS) TFT technologies, successfully compensates for threshold voltage...
This work demonstrates a novel pixel circuit composed of top emission architecture with a voltage programming method. Besides compensating for the threshold voltage variation of TFTs, the proposed circuit can improve the luminance degradation of active-matrix organic light-emitting diode (AMOLED) by using OLED voltage as a feedback of OLED luminance degradation. In addition, the reversed-bias voltage...
