  •      A projector, also known as a projector, is a device that can project images or video onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signals. It is an optical instrument that uses an optical element to magnify the contour of a workpiece and project it onto a screen. It can be used for profile measurement with transmitted light, or it can be used to measure the surface shape of the through hole and the surface of the part.
  •  
  •      At present, the touch one machine is an integrated 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, Print and other specific needs. The touch screen has four or five-wire resistive screens, 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.

  •      Today's multimedia classrooms are mainly divided into two categories. One is the projector as the main display device, and the other is the touch integrated machine as the display device. The composition of the touch integrated machine is: the touch integrated machine integrates the display large screen, the touch part, and the PC computer. The composition of the projector class is: projector + electronic whiteboard + PC computer + central control.

  •   Traditional projector PK touch one machine analysis:  
  •  
  • 1. Life aspect
  •  
  •      The large-screen display of the touch-one machine has a long life. According to the life of the regular screen, it will be basically 10 years. The PC part is classified as a "compatible machine", and the fault is relatively random. The touch part is realized by infrared touch. As the use time increases, the infrared tube will gradually age, causing the positioning to be inaccurate.
  •  
  •      The projectors basically used bulbs. With the development of technology, bulbs (such as BenQ) can achieve 10,000 hours of life. Now all major brand projection airports are launching laser projectors, and BenQ projectors have a lifespan of 30,000. More than an hour. The PC used with the projector, whether it is a desktop or a laptop or a PARD, can guarantee the longevity, at least not higher than the PC integrated with the touch integrated machine. Electronic whiteboards and central control products are now mature and the failure rate is not high. Therefore, in terms of life, the life of the two types of display devices is quite close.
  •  
  • 2. Touch aspect
  •  
  •      The touch-one machine supports ten-point touch, and the operator can directly touch or control by hand or any object, which is convenient and intelligent; but now the electronic whiteboard with the projector has more touch modes, and there are electromagnetic and infrared , optical, dot matrix, capacitive, and so on. Especially capacitive, just like the touch screen of a mobile phone, it is reliable, sensitive and durable. Therefore, in terms of touch, the projector is better than the touch one.
  •  
  • 3. Size aspect
  •  
  •      Now, with the development of technology, the touch-one machine is 65-inch, 75-inch, 86-inch, and 98-inch. Students behind the classroom can also see the displayed content. The display area of ​​the projector is basically unlimited. The general education classrooms are all 80 or 100 inches, and the college classrooms are 100 to 150 inches. The students behind the classroom can basically see the displayed content. Therefore, in terms of size, the projector wins the touch one.
  •  
  • 4. installation
  •  
  •      The weight of the 65-inch touch-one machine is almost 100 kilograms, and the 80-inch size is more than 200 kilograms. Now the school building is a frame structure, the walls of the classroom are hollow bricks, and there is no way to fix them. Such heavy equipment is not safe at all unless it is filled with cement or fixed through the wall. In addition, the all-in-one machine is basically installed in the mobile green board. For the sake of appearance, this will increase the difficulty of installation. The installation of the all-in-one machine requires at least three installers. The 80-inch all-in-one machine requires at least five people, but the projector is installed in one package. Only a maximum of two people are required. However, the one-piece machine will have less wiring than the projector, but now the wireless technology is getting more and more powerful, and the projector and the all-in-one can be installed with only the power cable.
  •  
  • 5. Maintenance aspects
  •  
  •      In terms of difficulty in maintenance, the touch all-in-one machine is obviously very troublesome, because the volume is too heavy, whether it is a PC failure or the failure of the all-in-one machine, it is necessary to remove the whole machine, repair it and then install it, this must be done once it is faulty. Individuals can go to the scene together, and for example, screen failures and touch failures cannot be solved locally, and need to be sent back to the manufacturer, so that several people need to be present at least twice to solve the problem. When sent back to the manufacturer, the costs, transportation risks and time incurred in the middle are all headaches for the users.
  •  
  •      In the past, the lamp life of the projector was short, but with the development of the light source technology and the popularity of laser projectors, the demand for consumables is becoming less and less, this piece will basically not cost, and the whole set of equipment can be independently repaired. The equipment can be repaired and localized, and the spare machine can be provided at any time without delaying the use of the equipment.
  •  
  • 6. Software package
  •  
  •      Now whether it is a touch-one machine or a projector plus an electronic whiteboard, the teaching methods, all-in-one machine and electronic whiteboard manufacturers are combined with teaching materials to integrate some teaching software, which is convenient for teachers to use at any time.
  •  
  • 7. Cost aspects
  •  
  •      The larger the size of the touch all-in-one, the weaker the price advantage. Now the cost of the laser projector plus electronic whiteboard, central control, and PC equipment is close to the cost of the 70-inch touch-one machine. With the popularity of laser projectors, the overall cost will further decline, even if the two are in accordance with the same price standard. Isn't it better to choose a larger display area?
