In this letter, we propose a new pixel circuit with low-temperature poly-silicon and oxide (LTPO) thin-film transistors (TFTs). The proposed pixel circuit can significantly reduce the power consumption of liquid crystal displays (LCDs) while maintaining their conventional features, by virtue of extremely low off-state current of n-type oxide TFTs and constant data voltages. Furthermore, p-type low-temperature poly-silicon (LTPS) TFTs can make the circuit simpler than when only n-type or p-type TFTs are used due to its complementary operation. By fabricating the circuit with the LTPO process, we successfully verify the circuit performance under continuous operation without further programming. Consequently, we believe that the proposed pixel circuit can provide low-power LCDs, even maintaining their conventional features.

一种由低温多晶硅和氧化物 TFT 组成的低功耗像素电路，用于具有面板自刷新技术的液晶显示器

在这封信中，我们提出了一种具有低温多晶硅和氧化物 (LTPO) 薄膜晶体管 (TFT) 的新像素电路。由于n型氧化物TFT的极低截止电流和恒定的数据电压，所提出的像素电路可以在保持其传统特性的同时显着降低液晶显示器（LCD）的功耗。此外，p 型低温多晶硅 (LTPS) TFT 由于其互补操作，可以使电路比仅使用 n 型或 p 型 TFT 时更简单。通过采用 LTPO 工艺制造电路，我们成功验证了连续运行下的电路性能，无需进一步编程。因此，我们相信所提出的像素电路可以提供低功耗 LCD，甚至可以保持其传统特性。
