The touch-one advertising machine is a mainstream type of advertising machine, which is applied to various fields. So, do you know the classification of the one-touch advertising machine? Let me talk about the classification of the touch-one advertising machine today.
1. Resistive touch integrated advertising machine
Controlled by pressure sensing. The main part of the resistance touch-sensitive machine is a resistive film screen that is very compatible with the surface of the display. It is a multi-layer composite film with a layer of glass or hard plastic as the base layer and a transparent oxidized metal on the surface. Conductive layer), which is covered with an outer surface hardened, smooth and anti-scratch plastic layer, and its inner surface is also coated with a lot of fine (less than 1/1000 inch) between them. The transparent isolation dots separate the two conductive layers from each other. When the finger touches the screen, the two conductive layers have contact at the touch point position, the resistance changes, and signals are generated in both 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), which then operates according to the way the mouse is simulated. This is the most basic principle of the resistive touch screen.
2. Capacitive touch one advertising machine
Working with the current sensing of the human body. The capacitive touch screen is a four-layer composite glass screen. The inner surface and the interlayer of the glass screen are coated with a layer of ITO. The outermost layer is a thin layer of bauxite glass protective layer. The interlayer ITO coating is used as the working surface. Four electrodes are taken out, and the inner layer of ITO is a shielding layer to ensure a good working environment. When the finger touches the metal layer, the user and the surface of the touch screen form a coupling capacitor due to the electric field of the human body. For high-frequency current, the capacitor is a direct conductor, and the finger sucks a small current from the contact point. This current is discharged from the electrodes on the four corners of the touch screen, and the current flowing through the four electrodes is proportional to the distance from the finger to the four corners. The controller calculates the position of the touch point by accurately calculating the ratio of the four currents. .
3. Infrared touch one machine
The infrared technology touch screen is composed of infrared emitting and receiving sensing elements mounted on the outer frame of the touch screen, and an infrared detecting net is formed on the surface of the screen, and any touch object can change the infrared rays on the contacts to realize the touch screen operation. The infrared touch screen is implemented in a similar way to surface acoustic wave touch, using infrared emitting and receiving sensing components.
These components form an infrared detection net on the surface of the touch-one screen, and an object (such as a finger) that is touch-operated can change the infrared rays of the electric shock, and is converted into a coordinate position of the touch to achieve an operation response. In the infrared touch screen, the circuit board device arranged on the four sides of the screen has an infrared transmitting tube and an infrared receiving tube, corresponding to forming an infrared matrix intersecting horizontally and vertically.
