本文介绍了一种由In-Zn-O (IZO) tft集成在聚酰亚胺衬底上的低功耗高稳定性扫描驱动器。从48级扫描驱动器的实验结果来看，输出波形没有失真，并且具有良好的噪声抑制特性。在所提出的扫描驱动器的一个级中，只需要一个小的TFT通过使用反馈逆变器和直流输出模块连接到时钟信号，以最小化动态功耗。在输出摆幅为15.3 V、时钟频率为50 kHz时，所提出的栅极驱动器的一级功耗为18.3 mu W。从300小时的测试中可以看出，所提出的扫描驱动器具有良好的噪声抑制特性和高稳定性。
This brief presents a low-power high-stability scan driver integrated by In-Zn-O (IZO) TFTs on polyimide substrate. Observed from the experimental results of the scan driver with 48 stages, there is no distortion and good noise-suppressed characteristics for the output waveforms. In one stage of the proposed scan driver, there only needs a small TFT connected to clock signals by using a feedback inverter and a dc output module to minimize the dynamic power consumption. It is measured that the power consumption for one stage of the proposed gate driver is 18.3 mu W at the output swing of 15.3 V and the clock frequency of 50 kHz. There is a good noise-suppressed characteristic and high stability for the proposed scan driver as shown from a 300-h test.
