Abstract

The invention discloses a printing ink printing method. One to two white printing ink layers are printed on the edge of a glass substrate of a touch screen, each white printing ink layer is of a frame-shaped structure, a black printing ink layer is further printed on each white printing ink layer and is of a frame-shaped structure, the inner edge of each black printing ink layer is located on theinner side of the inner edge of the corresponding white printing ink layer, and a black frame of the touch screen is formed by areas between the inner edges of the black printing ink layers and the inner edges of the white printing ink layers. The method is characterized in that components of each white printing ink layer comprise epoxy resin, titanium dioxide, a solvent, a dispersion agent, a defoaming agent, a flatting agent, an additive and modified nano-zinc oxide; and the additive is a mixture of 4-aminobenzoic acid, maleic acid, p-toluenesulfonic acid and sebacic acid. According to the method, the total thickness of the printing ink layers is greatly reduced, the risk that bubbles are generated in the capacitance screen attachment process is reduced, and therefore the yield is increased.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment production and processing, and in particular relates to an ink printing method for a glass cover plate. Background technique [0002] With the development of science and technology, touch-screen mobile phones are more and more favored by users, and the screen size of mobile phones becomes larger and larger. At present, in the capacitive screen manufacturing industry, the manufacture of the white model is more difficult than the black model. The reasons are: first, the cover plate is white, and the color of the TFT display module window is black. When the two are bonded together, there will inevitably be a bonding tolerance. According to the different equipment and process conditions of each factory, it is also different. Generally, the deviation is 0.1-0.2mm. Under this deviation, there will be a situation of large and small sides. In order to solve this problem, the industry will use...
