Design of compensation pixel circuit with In-Zn-O thin film transistor for active-matrix organic light-emitting diode 3D display

Abstract

This paper presents a new compensation pixel circuit suitable for active-matrix organic light-emitting diode (AMOLED) stereoscopic three dimensional (3D) displays with shutter glasses. The simultaneous emission method was used to solve the crosstalk problem, in which the periods of initialization and threshold voltage detection occur for each pixel of whole panel simultaneously. Furthermore, there was no need of the periods of initialization and threshold voltage detection from the second frame beginning by employing threshold voltage one-time detection method. The non-uniformity of the proposed pixel circuit was considerably low with an average value of 8.6% measured from 20 discrete proposed pixel circuits integrated by In-Zn-O thin film transistors (IZO TFTs). It was shown that the OLED current almost remains constant for the number of frames up to 70 even the threshold voltage detection period only exists in the first frame.
