  •      Touch one machine is an advanced touch screen, industrial control, computer and other technologies in one, can realize public information inquiry, with peripherals such as fingerprint instrument, scanner, card reader, micro printer, etc., can realize fingerprint attendance, credit card, printing, etc. Specific needs. The touch all-in-one is a touch product that bundles the touch screen with related software and is packaged for inquiries. The touch-one machine truly combines touch and control, greatly improving people's work efficiency.

  •      The realization of the touch technology of the large-sized touch one machine on the market is the credit of infrared touch. The application and popularity of infrared touch technology lies in its stability, ease of use and economy. Perhaps some customers will learn from the network and other ways, touch screen touch technology also contains the concept of optical touch.

  •   Infrared touch contrast optical touch advantage analysis of touch one machine: 
  •  
  • 1. Optical touch screen
  •  
  •      Optical touch technology is a kind of touch technology such as resistance and capacitance. The optical sensor responds to detailed actions quickly and can be applied to conference places, commercial exhibition places, education and training places, exhibitions, financial industry, and many industries. In principle, the optical touch skill is a new skill different from the existing contact skills of infrared, surface acoustic wave, resistance, capacitance, etc. The optical sensor responds quickly to detailed actions, making the application more light, fluent and accurate!
  •  
  •      In the practical application of the market, for example, the optical screen camera used in shopping malls, the principle is to rely on the two camera hairs on the left and the right to emit light to sense the contact points on the screen to form a contact. However, the current optical screen camera is far from the principle of its application. The existence of blind spots and false point contacts (inaccurate contact is a false point) is the current state of optical contact. The optical camera used is difficult to reach the principle requirements, resulting in the optical touch screen products currently used in shopping malls without product upgrades, and there is no advanced skills to improve it. In short, for the optical touch technology in one sentence, the principle of optical contact is very strong, but the skills can not be done!

  • 2. Infrared touch screen
  •  
  •      The principle of the infrared touch screen is to closely match the infrared matrix in the X and Y directions in front of the screen, and to continuously detect whether there is infrared rays blocked by the object and to locate the user's touch. When there is a touch, the finger or other object will block the horizontal and vertical infrared rays passing through the position. When the touch screen scans and finds that there is an infrared light blocked, the red light is on, indicating that the infrared light is blocked, there may be a touch, and immediately change to another The coordinates are re-scanned. If another axis is found, there is also an infrared block, and the yellow light is on, indicating that the touch is detected, and the position of the two infrared traps that are found to be blocked is reported to the host, and the position of the touch point on the screen is determined through calculation.
  •  
  •      The advantages of infrared touch screen: high stability, will not drift due to changes in time and environment. Irrespective of current, voltage and classic disturbance, suitable for harsh environmental conditions (dust and explosion proof); long life, high durability, not afraid of scratching, long touch life; good application characteristics, no need for contact, contact body No special requirements. Support USB, serial output, operating system compatibility, to meet the needs of large-size touch screen products.
