  •   Contrast analysis between projector and smart whiteboard:  
  •  
  • 1. Accessories comparison
  •  
  •      There are many accessories for the projector, such as remote control, converter, VGA cable, HDMI cable, and so on. Connect each line and debug the device before each use.
  •  
  •      The KONWHAI smart whiteboard eliminates these cumbersome accessories and does not require complicated wiring. It is as convenient and practical as using a home computer. It can read and display files directly by inserting a USB flash drive.
  •  
  • 2. Picture quality comparison
  •  
  •      There is a common drawback in projectors: they are greatly affected by light, and the picture is blurred in a high-brightness environment, and the visual experience is extremely poor.
  •  
  •      KONWHAI smart whiteboard adopts 4K high-definition large screen, the screen resolution is up to 3840x2160, about 8.3 million pixels, the color is pure and natural, the picture quality is smooth and delicate, and it can be clearly displayed regardless of the external light. Say goodbye to the "Little Black House" era of the conference.
  •  
  • 3. Functional comparison
  •  
  •      The projector only has a single display function.
  •  
  •      In addition to meeting the needs of high-definition display, KONWHAI smart whiteboard can also realize functions such as touch writing, multi-screen interaction, and remote meeting. It adopts infrared touch technology, supports multi-touch, can write, reduce, enlarge, move text on the screen, and can also increase the writing page, extend the writing space indefinitely, and the writing content can be sent to the e-mail or mobile phone scanning code.

  • 4. Comparison of service life and cost
  •  
  •      The projector lamp is the only consumable of the projector, which directly affects the cost of the user's later use. The projection lamp with a price of thousands of dollars is not cheap. Suppose a projector changes the bulb for an average of 2 years, a bulb of 1,000 yuan. In ten years, the cost of replacing the bulb is as high as 5,000 yuan. Together with the purchase of projectors, curtains and accessories, it costs more than 10,000 yuan.
  •  
  •      The life of KONWHAI smart whiteboard far exceeds that of the projector. Take the 65-inch smart conference tablet as an example. It only sells for 8999 yuan and can reach 60,000 hours. It can be used for at least 20 years according to the use of eight hours per day. Additional costs for curtains, bulbs, accessories, etc.
  •  
  •      Based on the above comparisons, we found that the KONWHAI smart whiteboard is superior and more cost-effective in terms of appearance, accessories, image quality, function, service life and cost.
