Abstract
The present invention discloses a switch control unit, a test apparatus and method for a liquid crystal cell. The switch control unit controls a signal input to the liquid crystal display driver and controls the output of the signal from the liquid crystal display driver accordingly, and includes a control signal generator and a switch module. The test apparatus for the liquid crystal cell comprises: a switch control unit connected with a gate driver, for controlling ON and OFF of a signal input to the gate driver and controlling ON and OFF of a gate scan signal accordingly. The test method for the liquid crystal cell comprises: inputting a test signal; controlling ON and OFF of a gate scan signal by controlling ON and OFF of a signal input to a gate driver so as to determine the badness positions on a screen.
