Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0029] see figure 1 , in an embodiment of the present invention, a surface treatment method of a high-intensity touch screen, comprising the following steps:
[0030] S1. Put the double-sided ITO glass into the degreasing agent, soak it at room temperature for 5 minutes, then clean it with a squeegee, and rinse it repeatedly with distilled water for 3-4 times;
[0031] S2. Put the degreased double-sided ITO glass into the etching solution, soak for 5 minutes ...

The invention discloses a surface treatment method for a high-strength touch screen, and relates to the technical field of touch screens. The surface treatment method comprises the following steps: S1, degreasing; S2, etching; S3, catalyzing; S4, activating; S5, reducing; and S6, chemically coating silver. According to the invention,after being treated through steps such as catalyzing and activating, a silver layer is deposited on ITO in a silver coating step, so that the silver coating effect is effectively improved,and certain corrosion resistance effect of the touch screen is achieved by sliver coating; moreover, light transmission and electrical conductivity are effectively improved, and the image-forming effect is optimized; lanthanum oxide and ceric sulphate in chemical silver-coating solution can have co-deposition with the silver coating, so that the coating is finer; and lanthanum oxide and ceric sulphate in certain weight ratio are added, and the lanthanum oxide and ceric sulphate are deposited along with the separation-out of the silver coating to charge the gaps of sliver replacement, and therefore, the coating is finer and is more compact, has metal gloss, and achieves the coating improvement effect.
Description
technical field [0001] The invention relates to the technical field of touch screens, in particular to a surface treatment method for high-strength touch screens. Background technique [0002] According to the working principle of the touch screen and the medium for transmitting information, the touch screen is divided into four types, which are resistive, capacitive, infrared, and surface acoustic wave. Each type of touch screen has its own advantages and disadvantages. To know which touch screen is suitable for which occasion, the key is to understand the working principle and characteristics of each type of touch screen technology. [0003] Tin-doped indium oxide thin film is a semiconductor material with excellent photoelectric properties and electrical conductivity. It has been widely used in touch screen technology. After sputtering ITO on the surface of capacitive touch screen glass substrate, it becomes double-sided ITO glass , the ITO films on different sides need ...
