Abstract

The invention provides a screen printing method for a black frame of a VA screen. The screen printing method comprises the following steps: S1, cleaning a glass substrate; s2, a first polaroid is attached to the upper surface of the cleaned glass substrate, and a second polaroid is attached to the lower surface of the cleaned glass substrate; s3, pressurizing and heating through a defoaming machine, and discharging bubbles among the first polaroid, the second polaroid and the glass substrate; s4, black ink is printed on the first polaroid through a screen printing plate and a screen printing machine; s5, a transparent protective film is attached to the surface of the side, away from the first polaroid, of the black ink. According to the method, the polaroid is firstly attached to the glass substrate, then the black ink is printed on the polaroid in a silk-screen mode, attachment of the polaroid and the glass substrate is more convenient, bubbles can be better eliminated, and polaroid loss caused by the bubble silk-screen problem is also avoided.

Description

technical field [0001] The invention relates to the technical field of frame screen printing, in particular to a method for screen printing of a black frame of a VA screen. Background technique [0002] With the development of technology, VA LCD screens are more and more widely used in the market. The main reason is that VA LCD screens have high black and white contrast. Compared with other LCD screens with black background and white characters, VA LCD screens have a darker background and a wider viewing angle range Wide; but the VA LCD screen is black because of the background color, the LCD screen frame and the edges around the screen are prone to white edges, and light leakage is more likely to occur after installation. The existing black frame silk screen printing on the edges of the product is easy to appear silk screen after the patch is defoamed. bubble. After the VA LCD screen is screen-printed with a black border, because there is a certain height difference betwee...
