Capacitive
Capacitive touch technology, can be customized according to different applications of several types of projective capacitive touch Glass-Film (GF) and Double-Sided-ITO (GFF); Glass-Film (GFF); Double-Sided-ITO (Glass-Film-Film (GFF)); Glass- -Glass (GG2), which have multi-point touch points and waterproof functions on the display.
Resistive
Resistive Touch Panels Today’s technology is quite mature, not only durable but also cost-effective 4-wire and 5-wire resistive technology, glass / glass touch screen provides tamper-proof and chemically stable applications. Zero-Bezel touch screen for design-oriented applications.
Infrared (IR)
Infrared (IR) touch panel on the four sides of the screen, there are X and Y axis infrared emitters and receivers. By using the light source to receive and interrupt the principle, when the infrared ray is obstructed by the contact in a specific position, The position of a contact as a finger.
Infrared touch is mainly used in large size applications and multi-touch, fast and very accurate reaction, but also extremely durable; disadvantage is limited by the infrared module size, can not be high-resolution, also with high power consumption.
Surface Acoustic Wave (SAW)
Surface Acoustic Wave, The surface of the touch panel is made entirely of glass. The ultrasonic wave transmitter and receiver at the three corners form a uniform sound field in the middle area when the surface wave touches the finger and soft medium will be absorbed energy, that is, produce acoustic cut-off, in order to calculate the touch position.
Surface Acoustic Wave(SAW) touch is not easy to be damaged, suitable for a variety of occasions, but the disadvantage is the high cost of upstream and downstream integration is not easy, the screen surface if there are drops of water and dust will make the touch screen becomes slow or does not work and can not do more detection measurement.While SAW differs from both projected capacitive and surface capacitive in its ability to be activated by different touch inputs, it’s harder to integrate. Durability also is a concern due to the sautered components.
