The touch screen overlay is a layer of material covering the display screen that enables touch functionality. With the continuous development of technology, the types of touch screen overlays are constantly increasing, with mainstream models including capacitive touch screens, resistive touch screens, infrared touch screens, acoustic touch screens, and surface acoustic wave touch screens.
2. Resistive Touch Screen: Resistive touch screens are a traditional touch screen technology that uses changes in resistance between two conductive films to achieve touch operations. Resistive touch screens have the advantages of low cost, durability, support for handwriting input, but have a slower response time and do not support multi-touch. They are mainly used in some industrial control equipment and older touch screen devices.
3. Infrared Touch Screen: Infrared touch screens use infrared sensors to achieve touch operations. They have high precision, are not affected by external light, and are durable, making them suitable for outdoor environments and large-sized touch screen devices.
4. Acoustic Touch Screen: Acoustic touch screens use ultrasonic sensors to achieve touch operations. They have high precision, are not affected by external light, and support multi-touch, making them suitable for special environments and high-end touch screen devices.
5. Surface Acoustic Wave Touch Screen: Surface acoustic wave touch screens use surface acoustic wave sensors to achieve touch operations. They have high sensitivity, high transparency, support for large-sized touch screens, and are widely used in large commercial display screens and information query devices.
In general, different types of touch screen overlays have their own characteristics and suitable scenarios. When choosing touch screen devices, users should choose the appropriate touch screen technology based on their actual needs and budget. With the continuous progress of technology, touch screen technology will continue to innovate and develop, providing users with more convenient and efficient touch operation experiences.
