Abstract A new pixel architecture and driving scheme for a low-power liquid crystal display (LCD) with a low refresh-rate is proposed. The proposed pixel architecture comprises two oxide thin-film transistors (Ox-TFTs), two ferroelectric memory TFTs (Fe-MTFTs), and two capacitors. Both TFTs have the same indium gallium zinc oxide film as an active layer. The Fe-MTFT exhibits a hysteresis property owing to the ferroelectric gate insulator that enables it to operate as a memory. A prototype LCD with 6 × 5 pixels is fabricated in this letter. The fieldeffect mobility of Ox-TFTs is 11 cm<sup>2</sup>V<sup>-1</sup>s<sup>-1</sup>. The memory window of Fe-MTFT is 5 V with a gate-voltage sweep from -20 to 20 V. After programming the Fe-MTFTs, the fabricated LCD successfully operates at a 0.5-Hz refresh-rate.
