This work presents a new pixel circuit composed of six low-temperature polycrystalline-silicon (LTPS) thin-film transistors (TFTs) and two capacitors for active-matrix organic light-emitting diode (AMOLED) displays. New auto-compensation method is developed by cancelling the reference voltage which is required in general compensation circuits, thus improving the aperture ratio of pixel. By adopting...
A new stereoscopic three-dimensional (3-D) active-matrix organic light-emitting diode (AMOLED) pixel circuit composed of amorphous indium-gallium-zinc-oxide thin-film transistors (a-IGZO TFTs) is presented in this paper. The proposed pixel circuit has simple structure by adopting external circuit shared in one column and successfully compensates for the threshold voltage variation of a-IGZO TFTs....
This letter presents a new pixel circuit reaching simultaneous compensation for a threshold voltage ($V_{{\rm{TH}}}$) shift of normally-<sc>off</sc> and normally-<sc> on</sc> a-IGZO TFTs, as well as luminance drop of an OLED device for ultrahigh-definition active-matrix organic light-emitting diode displays. Simulation results demonstrate the successful detection of a 1 V...
