  •      Touch screen technology is a new type of human-computer interaction input. Compared with traditional keyboard and mouse input methods, touch screen input is more intuitive. With the recognition software, the touch screen can also realize handwriting input.
  •  
  •      For operational convenience, people use a touch screen instead of a mouse or keyboard. The touch screen is composed of a touch detecting component and a touch screen controller, and the touch detecting component is installed in front of the display screen for detecting the touch position of the user, and then transmitting the related information to the touch screen controller.
  •  
  •      The main function of the touch screen controller is to receive touch information from the touch point detecting device and convert it into contact coordinates, which are then transmitted to the CPU. It can also receive commands from the CPU and execute them.

  •  
  •      The touch screen technology is divided into three types: nano touch screen, infrared touch screen, and capacitive touch screen. The three technologies realize that there is a big difference in price. This can plague users not making the right choice when purchasing a touch-enabled unit. To say which is better, can only say that there is no best, only more appropriate, one point price and one quality. Each touch technology has its own advantages and disadvantages. KONWHAI technicians will explain the advantages and disadvantages of touch-one touch technology for you.

  •   Touch one machine three touch screen technology features:  
  •  
  • 1. Touch one nano touch screen features:
  •  
  •      The Nano Touch Film is a transparent film that accurately senses the touch of a human hand and accurately positions the touch. The nano touch screen is composed of PET film, nano wire, control circuit board and driving software, and is composed of four parts. The nano touch film is the core component of the touch screen precise positioning device. Nano touch is more accurate, it is the most cost-effective, with short response time, long service life and light weight.

  • 2. Touch one machine infrared touch screen features:
  •  
  •      The infrared touch screen uses an infrared matrix densely arranged in the X, Y direction to detect and locate the user's touch position. The infrared touch screen is provided with a circuit board outer frame on the upper surface 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 rays at the position to locate the touch point on the screen.
  •  
  •      The infrared touch screen is a highly integrated electronic road integration product. It includes a complete integrated control circuit, and a set of high-precision, anti-jamming infrared emitters and a set of infrared receiver tubes. The crossovers form an invisible infrared grating in two opposite directions on a highly integrated circuit board. An intelligent control system embedded in the control circuit continuously pulses the diode to form an infrared polarization beam grid. When a touch object, such as a finger, enters the grating, the beam is blocked. The intelligent control system detects the loss of light and transmits the flag light to the control system to confirm the X-axis and Y-axis coordinates.
  •  
  •      The infrared touch has high adaptability and stability, and will not drift due to changes in time and environment, and is not affected by current, voltage and static electricity, and is suitable for some harsh environmental conditions (explosion-proof, dust-proof).
  •  
  • 3. Touch one machine capacitive touch screen features:
  •  
  •      A capacitive touch screen is a layer of transparent special metal conductive material attached to the surface of the glass. When the finger touches the metal layer, the capacitance of the contact changes, causing the frequency of the oscillator connected to it to change, and the position of the touch can be determined by measuring the frequency change. The capacitive touch sensitivity is high, and it is not affected by the light environment, and the effect is stable.
