Logic gates and inverter circuits are key components for on-panel digital signal processing and display driving circuitry. For this purpose, level shifters, shift registers, scan drivers and other circuit demonstrations have been developed using thin-film technology. However, in the absence of complementary transistors on a TFT technology, realization of even a simple inverter may take multiple inputs, and/or control bias signals which highlights a need for better implementation. In the literature, inverters using dual gate devices or hybrid devices and complex fabrication processes and multiple power rails were proposed to achieve the rail-to-rail operation and decrease power dissipation, but at the expense of significant cost and yield.

逻辑门和逆变器电路是板上数字信号处理和显示驱动电路的关键部件。为此，使用薄膜技术开发了电平移位器、移位寄存器、扫描驱动器和其他电路演示。然而，在没有TFT技术上的互补晶体管的情况下，即使是简单的逆变器的实现也可能需要多个输入和/或控制偏置信号，这突出了更好地实现的必要性。在文献中，逆变器被提出使用双栅器件或混合器件和复杂的制造工艺和多条电源轨来实现轨到轨的运行，降低功耗，但代价是显著的成本和成品率。
