Abstract: A liquid-crystal pixel unit includes a storage capacitor, a liquid-crystal capacitor, a data writing circuit, and a source-follower type output circuit. The storage capacitor includes a first electrode and a second electrode. The second electrode is configured to receive a first reference voltage. The liquid-crystal capacitor includes a third electrode and a fourth electrode. The fourth electrode is configured to receive a second reference voltage. The data writing circuit is electrically connected to the first electrode and the third electrode. The data writing circuit is controlled by a control signal to charge a data voltage into the storage capacitor and the liquid-crystal capacitor. The source-follower type output circuit includes an input terminal and an output terminal. The input terminal is electrically connected to the first electrode. The output terminal is electrically connected to the third electrode.
