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.

With an excimer laser annealing (ELA) process, maximum display size is limited by the laser beam length because performance variations of the transistors in the overlapped regions cannot be sufficiently compensated to remove the brightness non-uniformity. In this paper, a redundant pixel line design is proposed to remove overlap mura. A 4.82″ AMOLED was successfully fabricated in order to verify the panel design method.

RGB adjustable gamma compensation circuit to choose one of the three different gamma characteristics for each color has been integrated by LTPS TFT for AMOLED. A timing controller to generate all timing signals for a 6-bit data driver and a scanning driver has also been integrated by the TFT on the AMOLED panel.
