Abstract
This paper proposes an emission driver for active-matrix organic light emitting diode (AMOLED) displays using amorphous indium-gallium-zinc-oxide thin-film transistors (a-IGZO TFTs). The proposed circuit effectively eliminates shoot-through current in QB control block, achieving 97% reduction in power consumption compared to conventional one. It stably operates in both depletion and enhancement modes and supports pulse-width modulation (PWM) driving for better low gray level expression of AMOLED displays. Simulation results show that the proposed circuit has the robust performance for high-resolution AMOLED displays.
期刊介绍：
The IEEE Journal of the Electron Devices Society (J-EDS) is an open-access, fully electronic scientific journal publishing papers ranging from fundamental to applied research that are scientifically rigorous and relevant to electron devices. The J-EDS publishes original and significant contributions relating to the theory, modelling, design, performance, and reliability of electron and ion integrated circuit devices and interconnects, involving insulators, metals, organic materials, micro-plasmas, semiconductors, quantum-effect structures, vacuum devices, and emerging materials with applications in bioelectronics, biomedical electronics, computation, communications, displays, microelectromechanics, imaging, micro-actuators, nanodevices, optoelectronics, photovoltaics, power IC''s, and micro-sensors. Tutorial and review papers on these subjects are, also, published. And, occasionally special issues with a collection of papers on particular areas in more depth and breadth are, also, published. J-EDS publishes all papers that are judged to be technically valid and original.
