How does the screen sense touch?

Touch panel technology is a key theme in today's digital devices, including smartphones, tablet devices such as the iPad, screens on the back of digital cameras, Nintendo DS and Windows 7 devices. The term touch panel encompasses various technologies for sensing the touch of a finger or stylus. In this session, we'll look at the basic touchscreen sensing methods and describe the characteristics and best applications of each method.

While Finelink touch panels require a wide range of characteristics, the most important of which is display visibility, as well as accuracy of position sensing, quick response to input, durability, and installation cost, their characteristics are limited by the method used to sense touch input. Huge difference. Resistive touch panel, capacitive touch panel, surface capacitive touch panel, projected capacitive touch panel, surface acoustic wave (SAW) touch panel, optical touch panel, electromagnetic induction touch panel, each type of touch panel Each type has its own advantages and disadvantages. No single sensing method is currently overwhelmingly superior in all respects. Choose a product after considering the intended use and environmental factors.
