27.1: Integrated pMOS Gate Driver for a 3D AMOLED Display

Abstract

Simultaneous Emission with Active Voltage control (SEAV) is a strong candidate for crosstalk‐free driving of 3D Active Matrix Organic Light Emitting Diode (AMOLED) displays. A gate driver for a SEAV 3D AMOLED panel needs two operating modes: the simultaneous switching mode and the progressive scanning mode. However, conventional gate drivers can operate in only progressive scanning mode. In this paper, a new integrated gate driver to support both of these modes is proposed and applied to a prototype 3D AMOLED display panel.

P‐57: New Gate Driver Circuit for High‐Resolution and High‐Frame‐Rate AMOLED Displays with Simultaneous Emission Driving Method

“…SE driving method needs the same output waveforms for every row line in compensation period and progressive output waveforms row by row in data input period. Thus, Chung et al [9] proposed an integrated gate driver circuit that combines two functional blocks to generate the required waveforms of simultaneous switch and progressive scanning in a frame for 3D AMOLED pixel panel with SE driving method. Although the required waveforms can be successfully generated, the two functional blocks consisting of eight TFTs and two capacitors increase the complexity of the system.…”
