Teach you how to choose an appropriate touch screen is a new part in today's new product design. In the past three years, many touch screen factories have been born. Users may not be able to judge the quality of a touch screen produced by a certain company from the appearance. We propose some simple methods to see the quality of the product from the appearance.
In addition, there are 4-wire, 5-wire, 6-wire and 8-wire manufacturers on the market. Which design meets our needs? When you get a touch screen, check if there is a green print around the touch screen. The border, if any, can probably be guessed as insulating ink, but the insulating ink may also be a translucent color.
In any case, the design using insulating ink will be slightly inferior to the quality of the double-sided tape with base material. In addition, you can take a look at the design of the wire end. If the connection between the outlet tail and the touch screen itself is not strong enough, the touch screen is easily broken. If the touch screen is broken, there is little chance of repairing it. In addition, you can hold the touch screen in your hand and use a 60 degree angle to see if there are Newton rings on the surface. If there is a touch screen produced by Newton rings, it means that the factory has insufficient experience in dealing with Newton rings. Press the touch screen with your finger to see if the touch screen has upper and lower layers. If you feel it, it means that this factory still has a way to go to provide a good quality touch screen product.
Furthermore, we provide some views based on different touch screen designs. 4-wire design This is the most basic approach, and it is also the mainstream design of 90 percent touch screen factories today, because the X.Y axis lines of the touch screen are directly pulled out and converted through the touch screen controller to read the position touched by the user. The 4-wire design is best used for small size products. Small size refers to the size below 10.4''. Because the touch screen relies on the resistance of the surface resistance to calculate the touch position after adding voltage, the surface resistance may be The aging phenomenon is caused by the environment or other reasons, which is not easy to be felt by the user on the small-sized touch screen. A 4-wire touch screen would be a good choice. 8-wire touch screen 8-wire touch screen can make up for the phenomenon of 4-wire touch screen design and large size, so 8-wire touch screen is designed with a "sensing line" on each side, if the surface resistance is aging, it can rely on induction The line is adjusted back to normal immediately, so the 8-line design is the best design for sizes above 10.4". 5-line touch screen: The 5-line design means that both the X and Y axes are placed on the bottom glass. The conductive film above is just a sensing line. This design can only be used on large sizes, because the four-sided line area is wider than the 8-line line. Generally, the 5-line touch screen is more expensive than the 4-line and 8 The wire type should be higher. 6-wire touch screen 6-wire type is the 5-wire type design plus a "Grounding" (Grounding).
