  •      The touch all-in-one machine is a touch product that bundles the touch screen and related software together with the outer packaging for query purposes. The touch-control all-in-one machine truly achieves the function of integrating touch and control, greatly improving people's work efficiency. The touch screen has four or five wire resistance screen, surface acoustic wave screen, infrared screen, holographic nano touch film and other excellent touch screens at home and abroad, which can meet the application needs of users in different regions and places. Users only need to touch the screen of the machine with their fingers to quickly get the information they want, thus making the human-computer interaction more straightforward.

  •      Support USB interface touch screen, support handwriting input function, with other software can realize electronic whiteboard, drawing and other interactive functions. Resistive, capacitive, infrared, optical, sonic touch screen, precise positioning. High definition, no glass work, low environmental requirements, high sensitivity, suitable for working in various environments.

  •   Analysis of the difference between infrared touch screen and capacitive screen of touch one machine: 
  •  
  • 1. Difference in appearance
  •  
  •      The infrared touch screen has a groove, which is afraid of strong light, the machine is thicker and heavier, but the price is cheap. Multi-touch, support up to 36 touches, use ten fingers at the same time, touch without drift, automatic correction, and precise operation. You can touch with your finger or soft pen. High-density touch point distribution: more than 10,000 touch points per square inch. High definition, no glass work. Low environmental requirements and high sensitivity. Suitable for working in various environments.
  •  
  •      The capacitive screen is a four-layer composite glass screen. The inner surface and interlayer of the glass screen are coated with ITO (nano indium tin metal oxide), the outermost layer is a protective layer of silica glass with a thickness of only 0.0015mm, and the interlayer ITO coating As the working surface, four electrodes are drawn from the four corners, and the inner layer of ITO is the screen layer to ensure the working environment. Capacitive screen touch query all-in-one machine is more beautiful, more beautiful, thinner and lighter, is pure plane, easy to achieve waterproof function, and the reaction speed is more sensitive.

  • 2. Differential analysis on the system
  •  
  •      The touch principle of the infrared touch all-in-one machine is to emit XY lines through the infrared light tube, and the touch point is the sensing coordinate. The advantages of infrared touch are not affected by current, voltage and classic interference, suitable for harsh environmental conditions (dust and explosion-proof), long service life and long touch life. There are no special requirements for the touch body. In addition, it has a high degree of stability and will not drift due to changes in time and environment.
  •  
  •      The touch principle of the capacitive touch all-in-one machine is through a transparent relative positioning system. First of all, it is transparent, which can support multi-point touch, and the operation is more intuitive and more interesting. Since the capacitive touch screen needs to sense the current of the human body, only the human body can operate it, and it will not respond when touched with other objects, so the possibility of accidental touch is basically avoided. It can be seen that the characteristics of the two touch screens have their own advantages and disadvantages, and users can purchase them as needed.
  •  
  •      With the increasing maturity of infrared technology, infrared touch has a strong adaptability to the use environment and supports large-size touch screens. The size can be selected from 21.5 inches to 100 inches. Infrared touch technology is more and more widely used in the all-in-one touch machine industry, and is very popular among users. We can see it in business halls, postal business halls, tax collection halls, city streets (inquiry of city information), office buildings, airports, stations, banks, museums, libraries, exhibitions, hospitals, hotels, etc. Touch one machine.
