  •      Touch one machine is composed of advanced touch screen, motherboard, memory, hard disk, graphics card and other electronic components, and the working principle of traditional PC is no different. The touch one machine can dynamically display the three-dimensional model of the object and has a good interactive experience. The viewer can operate by the touch-one machine and “touch” the object at zero distance on the screen. The viewer can also rotate and zoom in any way on the screen of the touch-one machine, freely appreciate the object, and view the structure of the object in multiple angles and high definition. Details, shape, color, etc.
  •  
  •      Everyone knows that digital touch imaging is a kind of human-computer interaction device that is widely used in shopping malls, office buildings, etc., and it can quickly help people find what they need by simply touching the screen. Information. 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 touch screen used in the touch screen integrated machine mainly has three types of resistive touch screen, infrared touch screen and surface acoustic wave touch screen, so we do not know what touch screen is used in the KONWHAI touch screen integrated machine? In response to this problem, the following KONWHAI technical editor for everyone to explain.

  •  
  •   The screen classification and features of the touch one machine: 
  •  
  • 1. Infrared touch screen
  •  
  •      The infrared touch screen is used in the touch screen integrated machine, which is an infrared matrix in the X and Y directions in front of the screen. It can detect whether there is infrared light blocked by the object and locate the user's touch. The infrared touch screen has high stability, adaptability and light transmission, and it is not afraid of scratching, high durability, good use characteristics, no need for touch, no special requirements for the touch body, long service life and long touch life. In addition, the infrared touch screen supports large-size applications, and the current maximum size can be 100 inches. It is currently the largest size implementer of all touch screen technologies.

  • 2. Resistive touch screen
  •  
  •      he touch screen integrated machine uses a resistive touch screen, which is mainly controlled by pressure sensing. It has high transparency, high strength, high light transmittance, small insulation point and good visual effect. It can recognize any input signal such as finger (with or without gloves), pen, credit card, etc. Operate with a hard object.
  •  
  •      Advantages: The advantages of the resistive touch screen are that its screen and control system are relatively cheap, the response sensitivity is very good, and whether it is a four-wire resistive touch screen or a five-wire resistive touch screen, they are a completely isolated working environment, not afraid of Dust and moisture can adapt to a variety of harsh environments. It can be touched with any object and has better stability. Disadvantages: the outer film of the resistive touch screen is easily scratched and the touch screen is not available, and the multilayer structure causes a large loss of light. For handheld devices, it is often necessary to increase the backlight to compensate for the problem of poor light transmission, but this also Will increase battery consumption.
  •  
  • 3. Surface acoustic wave touch screen
  •  
  •      The surface acoustic wave touch screen is composed of a touch screen, a sound wave generator, a reflector, a sound wave receiver and the like. When the sound wave generator can transmit a high frequency sound wave across the screen surface, when the finger touches the touch screen integrated machine screen, the sound waves on the contact are blocked, thereby determining the coordinate position. The surface acoustic wave touch screen has extremely high resolution, long life, excellent scratch resistance, and is not affected by environmental factors such as temperature and humidity, and is most suitable for use in public places.
  •  
  •      Disadvantages: This technology was originally designed for smaller screen sizes, so it is not convenient for screen sizes larger than 30 inches. Because the technology cannot be packaged and is susceptible to surface contamination and moisture damage, it is not suitable for many industrial and commercial applications. Dirty surfaces can cause dark spots on the screen, requiring regular cleaning of the sensor and occasional adjustments. Based on the way the technology itself operates, it is also difficult to avoid unnecessary interference, such as interference from external sounds.
