Abstract

The invention discloses a liquid crystal display monitor and comprises a plurality of data wires, a plurality of scanning wires and a plurality of pixel units. Each data wire is used for transmission of a pixel data voltage. Each scanning wire is used for transmission of a driving signal voltage. Each pixel unit comprises a transistor, a liquid crystal capacitor and a regulating capacitor. The transistor comprises a first end, a second end and a control end and also comprises a first guide component arranged between the control end and the scanning wire; the first end is coupled with one datawire. The first pole of the liquid crystal capacitor is connected with a common pressure electrode and comprises a second guide component arranged between a second pole of the liquid crystal capacitor and the second end of the transistor. One electrode of the regulating capacitor is connected with the second pole of the liquid crystal capacitor. A welding zone is arranged between the other pole of the regulating capacitor and the scanning wire. The invention also discloses a repair method of the liquid crystal display monitor.
