In industrial environments, there are many choices for touch screen displays. Different touch technologies have advantages and disadvantages and can be applied to different application scenarios. In order to meet different needs, the screen touch mode of industrial displays can also be customized. Customization of touch mode can better meet the needs of various complex environments. Several common industrial touch technologies include resistive, capacitive, infrared and acoustic wave touch screens. These technologies can help you make more appropriate choices when customizing industrial displays.
4 different screen touch modes for industrial displays
1. Resistive touch screen
The biggest advantage of resistive touch screens is that they are durable and adaptable to harsh environments. Resistive touch screens identify the contact position through physical contact between two conductive layers, so there is no restriction on touch tools. They can be operated with fingers, gloves, stylus pens or even hard objects, and are not affected by environmental factors such as water, dust, and oil. They are very suitable for harsh environments such as manufacturing, chemical plants, and food processing. However, since the resistive screen relies on physical pressure to operate, the touch sensitivity is low, multi-touch cannot be achieved, the display effect is slightly poor, and the light transmittance is not as good as other touch technologies. This screen touch mode is more suitable for scenarios where gloves are required for operation or there is a lot of dust and liquid in the environment, such as factory production lines, medical equipment, and outdoor industrial equipment.
2. Capacitive touch screen
Capacitive touch screens can display high-definition and multi-touch. Capacitive touch screens use changes in human body charge to identify the touch point position. They have the advantages of sensitive operation, support for multi-touch, and excellent display effects. Capacitive screens have high light transmittance and good image clarity, which are very suitable for scenarios that require high-definition display, such as smart manufacturing equipment, automated control systems, and self-service terminal equipment. However, capacitive screens cannot be operated with ordinary gloves or hard objects, and are easily disturbed by water and moisture. Therefore, capacitive screens perform well in user experience and interactivity, and this screen touch mode is more suitable for high-precision operations and industrial scenarios that require frequent touches, such as industrial automation instruments, medical display equipment, and smart terminals.
3. Infrared touch screens
The first choice for large-size industrial displays. Infrared touch screens detect touch positions through infrared grids on the frame, and are independent of the screen material, so they can be touched with any object. The advantages of this technology are strong durability, not easy to wear, and can achieve large-size touch screens, which are very suitable for outdoor equipment, conference systems, and large industrial control panels. However, the disadvantage of infrared screens is that they are more sensitive to strong light environments, which may cause touch failure. Therefore, this screen touch mode is more suitable industrial equipment that requires large-size displays and is used outdoors, such as charging piles, vending machines, outdoor billboards, and large operation panels.
4. Acoustic wave touch screens
Acoustic wave touch screens identify touch positions by detecting changes in surface acoustic waves. They have high touch accuracy, sensitive operation response, very high light transmittance, and clear display effects. They are very suitable for high-precision operation scenarios, such as industrial testing equipment and medical instruments. However, this type of touch screen is easily affected by water, dust, and oil, and is difficult to maintain in harsh environments. Therefore, this screen touch mode is usually used indoors in scenarios with high requirements for touch accuracy and display effects, such as exhibition hall interactive equipment, high-end display terminals, and museum information query systems.
