摘要:
Devices and methods for increasing the aperture ratio and providing more precise gray level control to pixels in an active matrix organic light emitting diode (AMOLED) display are provided. By way of example, one embodiment includes disposing a gate insulator between a gate of a driving thin-film transistor and a gate of a circuit thin-film transistor. The improved structure of the display facilitates a higher voltage range for controlling the gray level of the pixels, and may increase the aperture ratio of the pixels.

提供了用于增加开口率并为有源矩阵有机发光二极管(AMOLED)显示器中的像素提供更精确的灰度级控制的装置和方法。 作为示例,一个实施例包括在驱动薄膜晶体管的栅极和电路薄膜晶体管的栅极之间设置栅极绝缘体。 显示器的改进的结构有助于用于控制像素的灰度级的更高的电压范围,并且可以增加像素的开口率。
