A pixel circuit includes a first switch, a storage circuit, a second switch, and a liquid crystal capacitor. The first node of the first switch is configured to receive a data signal, and the second node of the first switch is coupled with a first node point. The storage circuit is coupled with the first node point, and configured to receive a common voltage. The first node of the second switch is coupled with the storage circuit, and the second node of the second switch is configured to receive a boost signal. The liquid crystal capacitor is coupled between the first node point and the storage circuit. In response to the first switch is conducted, the second switch is conducted, or in response to the second switch is conducted, the first switch is conducted.
