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.

The present invention discloses a mask plate and manufacturing method thereof. The mask plate comprises a substrate formed with a transparent region, a non-transparent region and a semi-transparent region. The semi-transparent region comprises a semi-transparent film, and a middle portion of the semi-transparent region is formed so that the intensity of the light transmitted therethrough is reduced in a larger extent than that in which the intensity of the light transmitted through the portion other than the middle portion in the semi-transparent region is reduced, whereby the light transmitted through the semi-transparent region is uniform.

Mask plate and manufacturing method thereof

The invention provides a masking process using photoresist, comprising: attaching a compress mask plate to a substrate; coating photoresist in a mask pattern of the compress mask plate; baking the photoresist from the substrate side; removing the compress mask plate from the substrate to form a desired photoresist pattern on the substrate. The inventive method simplifies the photolithography process, thereby the process time is shortened and the yield is increased.
