Working Principle and Classification of Delta Touch Screens

As a professional touch screen manufacturer, Delta produces touch screens that work based on different induction principles, which can be divided into four main categories: resistive, capacitive, infrared and surface acoustic wave. Each type of touch screen has its own unique working principle and application scenarios. Understanding these differences can help users choose the most suitable product according to their actual needs.

Resistive touch screens are the most widely used type in industrial automation. Delta resistive touch screens use pressure sensing for control. The core component is a multi-layer composite film matched with the display surface. A glass or hard plastic plate is used as the base layer, the surface is coated with a transparent conductive oxide (ITO) conductive layer, and then covered with a plastic layer with hardened outer surface and smooth anti-friction. The inner surface of the plastic layer is also coated with an ITO coating, and many tiny transparent isolation points are used to separate the two conductive layers for insulation. When a finger touches the screen, the two conductive layers contact at the touch point, the resistance changes, and signals are generated in both X and Y directions, which are then sent to the touch screen controller. The controller detects the contact and calculates the coordinates of (X, Y), and then simulates the operation of the mouse to complete the corresponding action. The main advantage of resistive touch screens is that they are not affected by dust and water vapor, can be touched with any object (fingers, gloves, stylus, etc.), and have low manufacturing costs, making them very suitable for harsh industrial environments.

Among resistive touch screens, five-wire resistive touch screens use a ductile nickel-gold coating for the outer conductive layer. Because the outer conductive layer needs to be touched frequently, the use of ductile nickel-gold material can effectively extend the service life of the product, although the process cost is relatively higher, but it can bring a better user experience and longer service life. ITO is the main material used in both resistive and capacitive touch screens. When the thickness of ITO is reduced to less than 1800 angstroms, it will suddenly become transparent, with a light transmittance of 80%, which can ensure a clear display effect.

Capacitive touch screens work by using the body's current sensing. Capacitive touch screens have a four-layer composite glass screen. The inner surface and interlayer of the glass are coated with ITO. The outer layer is a thin silica glass protective layer. The ITO coating on the interlayer is used as the working surface. Four electrodes are drawn from the four corners, which can sense the user's finger touch. Capacitive touch screens have the advantages of multi-touch, high light transmittance and long service life, and are more and more widely used in commercial display and high-end industrial scenarios. Infrared touch screens are based on the principle of infrared grid detection. Infrared transmitting and receiving tubes are arranged on the frame to form an infrared detection grid. When an object blocks the infrared, the position of the touch point is detected. Infrared touch screens are not affected by current, voltage and static electricity, and are suitable for harsh industrial environments. Surface acoustic wave touch screens use ultrasonic waves to detect touches, with high clarity and good light transmittance, but are easily affected by temperature and humidity, requiring regular maintenance.
