FAQ
Answer: Touch screen displays can support multi-user interactions by accurately detecting and tracking multiple touch points simultaneously, allowing multiple users to interact with the screen at the same time.
Answer: Many touch screen displays feature durable and scratch-resistant
We offer a range of touchscreens including capacitive, infrared, and surface acoustic wave (SAW) touchscreens.
Some of our touchscreens are rated for waterproof and dustproof use, but please check the specifications of the individual products for more information.
Choosing the right touchscreen depends on a variety of factors, including the intended use, environment, and user requirements. Our team can help you choose the best option for your specific needs.
Here are some of the commonly used touch technologies in the industry. Each technology has its unique characteristics and advantages, catering to different application requirements. It's important to choose the right touch technology based on the intended use, environmental factors, and user preferences:
1. Capacitive Touch Technology: Capacitive touch technology uses the electrical properties of the human body to detect touch. It relies on the conductive properties of objects to register input. When a conductive object, such as a finger, comes into contact with the touch surface, it creates a disruption in the screen's electrostatic field, allowing the touch to be detected and registered.
2. Surface Acoustic Wave (SAW) Technology: SAW technology uses ultrasonic waves that are transmitted across the touch screen. When the screen is touched, a portion of the wave is absorbed, and the touch location is determined by analyzing the changes in the acoustic wave pattern. SAW technology offers high image clarity and durability.
3. Infrared (IR) Touch Technology: Infrared touch technology uses a grid of infrared light beams across the screen's surface. When an object touches the screen, it interrupts the infrared light beams, and the touch location is determined by analyzing the interruption pattern. IR technology provides high accuracy and reliability.
4. Optical Imaging Technology: Optical imaging technology uses cameras or sensors to capture the touch interactions on the screen. It detects changes in light or infrared patterns caused by touch and translates them into touch input. This technology offers excellent touch accuracy and can support multi-touch gestures.
5. Projected Capacitive (PCAP) Touch Technology: PCAP technology utilizes a grid of micro-fine wires embedded in the touch screen. When a conductive object touches the screen, it creates a change in the electrical field, and the touch location is detected by measuring these changes. PCAP technology provides excellent touch sensitivity, multi-touch support, and durability.
