Abstract

Apparatus and methods are provided for increasing the aperture ratio of pixels (62) in an active matrix organic light emitting diode (AMOLED) display (32) and providing more precise gray scale control of the pixels (62). As an example, one embodiment includes disposing a gate insulator (136) between the gate (80) of the drive thin film transistor (72) and the gate (86) of the circuit thin film transistor (74). This improved structure of the display (32) facilitates a higher voltage range for controlling the gray scale of the pixels (62) and can increase the aperture ratio of the pixels (62).
