The essence of the touch screen is a sensor. At present, according to the type of sensor, the touch screen is roughly divided into four types: infrared type, resistance type, surface acoustic wave type and capacitive type.

The infrared touch screen is equipped with a circuit board frame in front of the display. The circuit board arranges infrared emitting tubes and infrared receiving tubes on the four sides of the screen to form a horizontal and vertical infrared matrix. When the user touches the screen, the finger will block the horizontal and vertical infrared rays passing through the position, so the position of the touch point on the screen can be determined. Any touch object can change the infrared ray on the contact to realize the touch screen operation. The infrared touch screen is not subject to current, voltage and electrostatic interference, and is suitable for some harsh environmental conditions. Its main advantages are low price, easy installation, no need for card or any other controller, and it can be applied to computers of all levels.

The main part of the resistive touch screen is a resistive thin film screen that fits well with the display surface. Two layers of OTI transparent oxide metal conductive layers are coated on the reinforced glass surface. Pressure sensing is used for control. When a finger touches the screen. The two conductive layers contact at the touch point, and the resistance changes. Signals are generated in the X and Y directions and then transmitted 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 the mouse. The resistive touch screen is not afraid of dust, water and dirt, and can work in harsh environments. However, because the outer layer of the composite film is made of plastic material, the explosion resistance is poor, and the service life is affected to a certain extent.

Surface acoustic wave is a kind of mechanical wave propagating along the surface of medium. An ultrasonic transducer is mounted on the corner of the touch screen. It can send a high-frequency sound wave across the screen surface. When the finger touches the screen, the sound wave on the contact is blocked, thereby determining the coordinate position. The surface acoustic wave touch screen is not affected by environmental factors such as temperature and humidity. It has high resolution, excellent scratch resistance, long service life, high light transmittance, and can maintain clear and bright image quality. It is most suitable for use in public places. However, dust, water and dirt will seriously affect its performance, which requires frequent maintenance to keep the screen clean.

This touch screen works by using the current induction of the human body. A layer of transparent special metal conductive material is pasted on the glass surface. When a conductive object touches it, the capacitance of the contact will be changed, so that the touched position can be detected. But there is no response when touched by a gloved hand or a hand-held non-conductive object because a more insulating medium is added. The capacitive touch screen can well sense light and fast touch, is scratch resistant, and is not afraid of dust, water and dirt. It is suitable for use in harsh environments. However, because the capacitance varies with temperature, humidity or environmental electric field, its stability is poor, its resolution is low, and it is easy to drift.

At present, the mainstream is multi touch, and Projected Capacitive multi touch, called PCAP for short. All jutouch touch panel mainly choose this PCAP technology. And the following touch performances are optional according to different final application:

Raspberry Pi OS provides touchscreen drivers with support for ten-finger touch and an on-screen keyboard, giving you full functionality without the need to connect a keyboard or mouse.

The 800 x 480 display connects to Raspberry Pi via an adapter board that handles power and signal conversion. Only two connections to your Raspberry Pi are required: power from the GPIO port, and a ribbon cable that connects to the DSI port on all Raspberry Pi computers except for the Raspberry Pi Zero line.
