working principle
The capacitive touch screen all-in-one machine is controlled by pressure sensing.
The main part of the resistive touch all-in-one machine is a resistive film screen that fits well with the surface of the display. This is a multi-layer composite film. It uses a glass or hard plastic plate as the base layer, and the surface is coated with a layer of transparent oxide metal (transparent). Conductive resistance) conductive layer, covered with a layer of hardened outer surface, smooth and scratch-resistant plastic layer, its inner surface is also coated with a layer of coating, there are many small (less than 1/1000 inch) between them The transparent isolation point separates the two conductive layers for insulation.
When the finger touches the screen, the two conductive layers are in contact at the touch point, the resistance changes, signals are generated in the X and Y directions, and then sent to the touch screen controller. The controller detects this contact and calculates the position of (X, Y), and then operates according to the way of simulating a mouse. This is the most basic principle of resistive technology touch screens.
The capacitive screen is purely flat and has an absolute advantage in structural design. The appearance is more beautiful and the surface is waterproof. If used outdoors, the capacitive screen can resist light interference, and the stability of the capacitive screen is better. The touch response speed of the capacitive screen is 3ms, and the response speed is faster.
Product advantages
1. The touch all-in-one machine can dynamically display the three-dimensional model of the object, and has a good interactive experience function. Users can operate by themselves through the touch all-in-one machine, and "touch" objects at zero distance on the screen. At the same time, they can also rotate and zoom arbitrarily on the touch-all-in-one machine screen, freely appreciate the object, and view the structure of the object from multiple angles and high-definition. , Shape, color and other details.
In addition, the touch all-in-one machine is also equipped with vivid and concise introduction of object information and related knowledge. While the three-dimensional display of objects enriches the form and content of the exhibition, it also satisfies the audience's curiosity and curiosity to a greater extent, and makes the masses The visit and learning became vivid and interesting.
2. Touch technology, support USB interface touch screen, support handwriting input function, and cooperate with other software to realize electronic whiteboard, drawing and other interactive functions.
3. Adjustable touch dedicated base.
4. Multi-touch, ten fingers are used at the same time, your sharp operation will make other users ashamed.
5. Capacitive touch screen, precise positioning.
6. Touch without drift, automatic correction, precision operation possible.
7. It can be touched with fingers and capacitive pen.
8. High definition, no glass work. The environmental requirements are not high, and the sensitivity is high. Suitable for working in various environments.
9. Equipped with a high-performance capacitive touch screen with a life span of more than one million clicks, no mouse and keyboard are required. All the operations of the computer can be realized by lightly tapping or swiping across the screen with your fingers, making the computer easier to use. Touching the computer The biggest innovation is that it uses multi-touch technology, which completely changes the way people interact with computers.
Maintenance guide
The capacitive touch all-in-one is a kind of high-tech electronic product. The technical coefficients involved are very complicated and the price is relatively expensive. However, our equipment still needs proper time for cleaning and maintenance work, otherwise it will greatly damage the capacitive touch all-in-one. Item parts and software.
