A new memory‐in‐pixel (MIP) circuit using oxide thin‐film transistors (TFTs) to achieve low power consumption is proposed. The display employing the proposed pixel circuit can greatly reduce the power consumption due to extremely low leakage current of oxide semiconductor TFTs. By fabricating the circuit with oxide TFT process, the circuit performance under continuous operation is successfully verified without additional programming. The power consumption in the panel (except backlight) can be reduced to 0.03% of that of conventional LCD.
