Abstract

The invention provides a liquid crystal pixel unit which comprises a storage capacitor, a liquid crystal capacitor, a data write-in circuit and source follower. The storage capacitor is provided with a first electrode and a second electrode. The second electrode is used for receiving a first reference voltage. The liquid crystal capacitor is provided with a third electrode and a fourth electrode. The fourth electrode is used for receiving a second reference voltage. The data write-in circuit is electrically conneted with the first electrode and the third electrode. The data write-in circuit is controlled by a control signal to store the data voltage in the liquid crystal capacitor and the storage capacitor. The source follower is provided with a input terminal electrically connected with the first electrode and a output terminal electrically connected with the third electrode. The liquid crystal pixel unit can solve problem of accurate voltage of the liquid crystal capacitor.

Description

technical field [0001] The present invention provides a liquid crystal pixel unit, especially a liquid crystal pixel unit for maintaining liquid crystal voltage. Background technique [0002] With the development of display technology, in addition to developing liquid crystal display devices with liquid crystal elements, light emitting devices with self-luminous elements, and field emission displays (FED), display manufacturers are also gradually paying attention to the display quality of liquid crystal displays. Requirements, such as display resolution, contrast, viewing angle, grayscale inversion, and color saturation specifications. In addition, the response time of liquid crystal displays is also one of the items that display manufacturers are rushing to study. Current liquid crystal modes with high-speed response characteristics, such as Ferroelectric Liquid Crystal (FLC) mode, Optical Compensated Birefringence (OCB) mode, and Blue Phase Liquid Crystal (BPLC) mode. ...
