Abstract
The invention discloses anti-scratching insulating protective liquid for a capacitive touch screen. The protective liquid is characterized by mainly consisting of the following components in percentage by weight: 10-40% of acrylic resin, 3-10% of silica, 50-85% of reactive diluent, and1-3% of auxiliaries. The sum of contents of each component is 100%. The anti-scratching insulating protective liquid can be made on the surface of the touch screen through a simple dip coating method, and has good transparency and uniform thickness, and forms a film after being dried in an oven with no need of other complicated devices. The solidified film has the advantages of glossy smooth surface, high light transmittance, excellent hardness and adhesion, and good insulating property.
Description
Technical field
The present invention relates to touch screen technology, especially a kind of long and narrow electrode that plates for the protection of touch-screen four limits and the effect protection liquid that plays insulation, specifically a kind of capacitive touch screen of anti-scratch insulation is with protection liquid.
Background technology
Along with the development of science and technology, touch screen technology has had significant progress, particularly multi-point touch panel, with respect to touch screens, the electric capacity touch screen more easily realizes, As time goes on, capacitance plate might become a trend, more is applied to the touch material of intelligent machine.Also need to solve simultaneously technology and protection problem in the production process in the process of development, the protection of the electrode on touch-screen four limits is exactly an aspect.
The structure of the touch-screen of capacitive technologies mainly is at the thin-film body layer of glass screen plating layer of transparent at present, adds the lastblock protective glass at the thin-film body layer again, and conductive layer and inductive layer can be thoroughly protected in two glass designs.Capacitive touch screen all plates long and narrow electrode on touch-screen four limits, forms a low-voltage AC electric field in electrical conductor.When touch screen, because people's bulk electric field, can form a coupling capacity between finger and conductor layer, the electric current that four limit electrodes send can flow to the contact, be directly proportional with the distance of finger to electrode and electric current is strong and weak, be positioned at ratio and power that controller after the touch screen just can calculate electric current, accurately calculate the position of touch point.
The electrode circuit on touch-screen four limits directly is connected with conductive layer; it is an important step of touch-screen normal operation; for the electrode that prevents touch-screen four limits sustains damage in the process of operation; guarantee simultaneously the insulation of electrode in the use procedure, need to make the layer protecting film guard electrode at the electrode on touch-screen four limits.
Summary of the invention
The present invention be directed in the touch-screen production process and need to make the layer protecting film guard electrode at the electrode on touch-screen four limits; invent a kind of capacitive touch screen of anti-scratch insulation with protection liquid, produce the rete that satisfied protection touch screen protective requires by czochralski process.
