Touch screen is a new part in today's new product planning, in the past few years there are many touch screen factories born, users may not be able to judge the quality of a touch screen produced by a company from the appearance, we propose some simple ways to see the quality of the product from the appearance.
There are 4-wire, 5-wire, 6-wire and 8-wire manufacturers on the market, which plan meets our needs? There are two kinds of lamination of the touch screen: water glue lamination and double-sided adhesive lamination. When you get a touch screen, look at whether there is a green border printed on the side of the touch screen, and if there is, you can probably guess that it is the edge of the ink, and the edge of the ink may also be a translucent color. Then this variety should be glued together, and the ink has the effect of isolating the upper base line. In this way, the touch screen is not resistant to high temperature, and cannot be suitable for complex harsh environments (such as high temperature and high humidity), and the anti-interference can not be strong. Others can see that the line is really planned, and generally this process will have a gap between the tail and the screen. If the glue used by the manufacturer is not high-grade information, the tail and the touch screen itself sticking force is not good, after the change of temperature and humidity, or the lack of attention when artificial installation, the tail will cause the line to crack, the touch screen is easy to break, if the touch screen is broken to correct the opportunity is not large.
In addition, if you can hold the touch screen in your hand and use a 60° viewpoint to see if there is a Newton ring on the surface (a kind of rainbow pattern that makes people look a little faint), if there is a touch screen with a Newton ring, it means that the factory is not able to deal with the problem of Newton rings. Press your finger on the touch screen to feel if the touch screen has two layers, or if there are bubbles. If it is felt, it shows that the factory still has some way to go to provide an outstanding quality touchscreen product.
