The Working Principle of Touch Screen Pos

- Oct 16, 2018-


      The touch screen pos machine is an integrated touch screen, industrial control, computer and other technologies. It can realize public information inquiry, and is equipped with peripherals such as fingerprint reader, scanner, card reader and micro printer. It can realize fingerprint attendance, credit card printing, printing, etc. Specific needs.


      The touch screen has four or five-wire resistive touch, surface acoustic wave screens, infrared screens, holographic nano-touch membranes and other excellent touch screens at home and abroad, which can meet the application needs of users in different regions and places.


      The touch all-in-one is a touch product that bundles the touch screen and related software together with the outer packaging for inquiry purposes. The touch-one machine truly combines touch and control, greatly improving people's work efficiency.

      The infrared touch screen used in the touch-one machine detects and locates the user's touch by using an infrared matrix densely arranged in the X and Y directions.


      The infrared touch screen integrated machine is equipped with a circuit board outer frame on the front side of the display, and the circuit board arranges an infrared emitting tube and an infrared receiving tube on the four sides of the screen, one by one corresponding to an infrared matrix intersecting horizontally and vertically.


     When the user touches the screen, the finger blocks the two infrared whiteboard lines passing through the position, so that the position of the touch point on the screen can be determined. Infrared touch screen is a highly integrated electronic circuit integration product.


     The infrared touch screen all-in-one includes a complete integrated control circuit, and a set of high-precision, anti-jamming infrared emission tubes and a set of infrared receiver tubes that are cross-mounted in two opposite directions on a highly integrated circuit board to form an invisible Infrared grating. An intelligent control system embedded in the control circuit continuously pulses the diode to form an infrared polarized beam grid.


     When a touch object, such as a finger, enters the grating, the beam is blocked. The intelligent control system will detect changes in light loss and transmit signals to the control system to confirm the X-axis and Y-axis coordinate values.
