Pcap Touch Screen Technology

More and more designs also in embedded computing choose the projective capacitive technology pcap touch to turn the surface in front of the display into a modern user interface.

Pcap touch screen technology.

Industrial pcap touch screen technology the majority of touch screens of today use one of two technologies projected capacitive or analogue resistive. Touch screen technology may have come a long way since 1966 but choosing the wrong touch screen for your application can make it just as expensive and difficult to use as the first ever touch screen. Custom designed projected capacitive pcap touch screens deliver pinpoint accuracy with multi touch functionality. The sensor glass the cover glass and a flexible printed circuit to the controller.

Projected capacitive pcap touch technology is most commonly used in smartphones and tablets but is quickly becoming a favored option for larger touch screen options and terminals. Ir touch technology involves an embedded overlay of infrared beams from top to bottom and side to side around the device s bezel. Projected capacitive touch screen technology does not require a bezel. This technology works by using a conductive grid that recognizes changes in its electromagnetic field caused by touch from a finger stylus or gloved hand.

The system continuously monitors the movement of each tiny capacitor to find out the exact area where the finger had touched the screen. The pcap touch screen technology is the newest generation of capacitive touchscreens a further development of the surface capacitive touch. Industrial customers profit from. Pcap is the most widely used touch technology today and offers more responsiveness allowing for added finger operations such as swiping pinching zooming rotating and even responding to.

Pcap touch panels can handle up to 10 touches simultaneously. Pcap displays very accurate and capable of up to 60 touch points. Pcap touch screens are usually used for consumer products like smartphones or tablets. A touchscreen or touch screen is both an input and output device and normally layered on the top of an electronic visual display of an information processing system the display is often an lcd or oled display while the system is usually a laptop tablet or smartphone a user can give input or control the information processing system through simple or multi touch gestures by touching the.

Pcap and resistive touch screens as well as the numerous others available on the market have advantages and disadvantages. Projected capacitive sensors are made up of three major components. Pcap touch screens are equipped with a network of electrodes metal mesh silver nanowire ito that project an electromagnetic field that also passes through a protective glass. The pct touchscreen enables new and revolutionary technical and usage possibilities.

The human body acts an electrical charge conductor so that when a finger touches the capacitive surface it changes the local electrostatic field.
