Abstract

The invention discloses a liquid crystal light alignment circuit which comprises a first liquid crystal display panel, a second liquid crystal display panel, a first public electrode, a second public electrode, a third public electrode, a fourth public electrode, a first field effect transistor and a first welding disc, wherein the first public electrode and the second public electrode are connected together and are both connected with the first liquid crystal display panel; the third public electrode and the fourth public electrode are connected together and are both connected with the second liquid crystal display panel; the source area of the first field effect transistor is connected with the second public electrode; the drain area of the first field effect transistor is connected with the third public electrode; the first welding disc is connected with the grid area of the first field effect transistor; when the first public electrode and the first liquid crystal display panel or the fourth public electrode and the second liquid crystal display panel are abnormally connected, the first welding disc can be electrified to communicate the second public electrode with the third public electrode. By adopting the liquid crystal light alignment circuit, normal liquid crystal light alignment voltage can be provided. The invention further discloses a liquid crystal panel.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal light alignment, in particular to a liquid crystal light alignment circuit and a liquid crystal panel using the liquid crystal light alignment circuit. Background technique [0002] Liquid crystal photo-alignment technology refers to the application of voltage to the liquid crystal panel, through the irradiation of ultraviolet light, to promote the monomer reaction in the liquid crystal, so that the liquid crystal molecules form a pre-tilt angle, so as to achieve the purpose of liquid crystal photo-alignment. The liquid crystal panel includes a CF (ColorFilter, color filter) substrate, a liquid crystal layer, and a TFT (ThinFilmTransistor, thin film transistor) substrate. The CF substrate and the TFT substrate are respectively provided with an indium tin oxide transparent electrode layer, and the indium tin oxide transparent electrode layer The surface of the liquid crystal panel is...

AI Technical Summary

Problems solved by technology

The array test is prone to ESD (Electro-Static discharge) problems due to the accumulation of static charges on the machine. The liquid crystal photo-alignment wiring with the same circuit as the array test is likely to be pulled down due to the above-mentioned faults, causing abnormal alignment problems when the liquid crystal is photo-aligned
