Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] Please refer to Figure 1~Figure 4 , an embodiment of a method for preparing a strengthened single-layer glass touch screen proposed by the present invention. This embodiment selects size as 800mm 800mm, ordinary glass with a thickness of 1.8mm is used as the glass substrate. According to market needs, ordinary glass or plexiglass with a thickness of 1.5mm, 1.1mm or 0.7mm and various sizes can also be selected to prepare a single-layer touch screen. The preparation method includes the following steps:
[0029] Step 1: Coating
[0030] A layer of conductive film 2 is first plated on the glass base material 1, and then a layer of temperature-resistant protective film 3 used as the conductive film is plated on the conductive film. In this embodiment, the conductive film 2 is a commonly used indium tin oxide film, and the temperature-resistant p...

The invention discloses a preparation method of a reinforced single-layer glass touch screen. The preparation method comprises the following steps: plating a conductive film and a temperature-resistant protective film on a glass substrate; etching a circuit on the coating film of the glass substrate; dividing the glass substrate into unit substrates, and then polishing the appearance of the glasssubstrate; soaking the unit substrate in a potassium nitrate solution at a set temperature for toughening treatment; removing the temperature-resistant protective film on the surface of the connectingpoint of the unit substrate, which needs to be externally connected with the component; and finally, electrically connecting the conductive film at the connection point with the touch IC by using conductive ink to obtain the touch screen. According to the invention, a layer of temperature-resistant protective film is plated on the conductive film of the glass substrate, and the glass substrate issubjected to high-temperature strengthening treatment. Damage of the conductive film is prevented, and the strength of the glass substrate is greatly improved. After the protective film is removed, the connecting point of the conductive film is electrically connected with the touch IC by using the conductive ink so that the conductive reliability of the conductive film is ensured.
Description
technical field [0001] The invention relates to the technical field of glass touch screen preparation, in particular to a preparation method of a strengthened single-layer glass touch screen. Background technique [0002] As the latest computer input device, the touch screen is a simple, convenient and natural way of human-computer interaction. It endows multimedia with a new look and is a very attractive new multimedia interactive device. This currently the easiest human-computer interaction technology has been pushed to many fields. In addition to being applied to personal portable information products, it is also widely used in household appliances, automobiles, public information (such as e-government, banks, hospitals, electric power and other departments) business inquiries, etc.), electronic games, communication equipment, office automation equipment, information collection equipment and industrial equipment, etc. As an interactive input device, users only need to l...
