[0049] Such as image 3 As shown, the method for preparing a touch panel according to one embodiment can be used to prepare the above-mentioned touch panel. The preparation method of the touch panel comprises the following steps:
[0050] Step S210: providing a cover plate, on which a non-visible area is provided.
[0051] The cover plate can be a transparent glass plate, a quartz plate, an aluminum oxide plate or a transparent organic plate. A non-visible area is arranged on the cover plate. Specifically, the cover plate has a display area and a non-visible area surrounding the display area, and the non-visible area is arranged at the non-visible area.
[0052] Step S220: forming a color-changing layer on one surface of the cover plate, and the color-changing layer is located at the non-visible area.
[0053] The material of the color-changing layer is angular color-changing ink. Wherein, the angular color-changing ink is a transparent or translucent thermosetting ink, f...
Embodiment 1
[0073] The preparation steps of the touch panel of this embodiment are as follows:
[0074] (1) Use polyester mesh to screen-print angle-changing ink on one surface of the glass cover and corresponding to the position of the non-visible area, and cure it at 170°C for 5 minutes to form a color-changing layer with a thickness of 5 microns. The color-changing ink includes the following components in parts by mass: 60 parts of thermosetting resin, 20 parts of color-dependent pigment, 30 parts of solvent, 5 parts of diluent, 1 part of leveling agent and 1 part of defoamer. The solid resin is epoxy resin; the angle-dependent color pigment is titanium dioxide mica pigment; the solvent is ethanol; the diluent is acetone; the defoaming agent is polyoxyethylene polyoxypropylene pentaerythritol ether. The leveling agent is polyacrylate.
[0075] (2) Screen printing forms the first ink layer, the second ink layer and the black ink layer on the discoloration layer to obtain the light-shie...
Embodiment 2
[0078] The preparation steps of the touch panel of this embodiment are as follows:
[0079] (1) Use steel mesh to screen-print angle-changing ink on one surface of the glass cover and corresponding to the position of the non-visible area, and cure it at 130°C for 20 minutes to form a color-changing layer with a thickness of 3 microns, which is angle-changing The ink includes the following components in parts by mass: 70 parts of thermosetting resin, 10 parts of color-dependent pigment, 20 parts of solvent, 7 parts of diluent, 0.5 parts of leveling agent and 2 parts of defoamer, among which, thermosetting Type resins are alkyd resins, phenolic resins and fluorocarbon resins; the color-dependent pigments are aluminum powder, titanium dioxide, carbon black, phthalocyanine blue and iron red; solvents are dichloromethane, ethyl acetate and butyl glycol ether; the diluent is butanol, cyclohexanone and xylene; the defoamer is polyoxypropylene glyceryl ether, polyoxypropylene polyoxye...
