1. So sánh đặc điểm chức năng: phấn viết bảng là chủ yếu
When buying any product, the first consideration is whether its functions can meet your own needs. This is one of the judging factors for mass consumers' choice and purchase, as is the education equipment industry. The interactive principle of the teaching all-in-one machine and the nano touch blackboard is different. The former uses infrared touch, and the latter uses an improved capacitive touch (nano touch). Both products cover multimedia teaching and touch interaction functions. However, because the nano touch blackboard relies on the internal nano touch film to achieve touch sensing, it does not need the transmitting/receiving line of the frame to sense and locate like an infrared screen, so it can be mimicked and flat, and it looks like ordinary blackboards. the difference. More importantly, more importantly, it inherits the original basic chalk writing functions of the blackboard.

2. Contrast of imaging clarity: high-definition but also eye protection
Compared with the projection electronic whiteboard, the imaging clarity of these two products can be described as a leap in quality. The 1080P high-definition display technology ensures the clarity of the picture, and the colors are full and vivid. However, there are some shortcomings in the teaching of integrated computers, such as large radiation and glare on the screen, which will have a certain impact on vision. In this regard, the nano touch blackboard is much better. Adding a nano-coating on the surface can filter 80 percent of harmful light and effectively protect the eyesight of users.
3. Use cost comparison: consider the comprehensive use cost
Price is also an important issue that users pay attention to. In the initial purchase cost, the nano touch blackboard of the same size is slightly higher than the teaching all-in-one machine, but with the mass production of large-size touch screens, the price of the whole machine is believed to be more and more landing. However, in practical applications, the service life of the nano touch blackboard is more than 50,000 hours, and the service life of the teaching integrated machine is about 40,000 hours. In the selection process, users should not be limited to purchasing, but should consider additional factors such as service life and application environment.
4. Application environment comparison: choose according to needs
As mentioned above, we can see that the two products have different technical principles, different functions and characteristics, and different application environments. The teaching all-in-one machine cannot write with chalk, and uses the touch interactive mode. The nano touch blackboard can realize the interactive mode of chalk and touch screen, each with its own advantages.
5. Convenience comparison: use and maintenance must be thoughtful
Both products integrate the functions of display and touch devices, making installation and debugging relatively easy. In terms of system, both Windows and Android are relatively familiar, and teachers can use it easily. It is worth noting that push-pull blackboards are commonly used in all-in-one teaching, which virtually increases the complexity of teachers' use in class, consumes teachers' physical strength, and reduces classroom teaching efficiency. At the same time, maintenance and upgrades cannot be ignored. Most of the teaching all-in-one computers are fixed hosts, and the modular design of the Nano Touch Blackboard PC uses a plug-in host, so it is much easier to maintain and upgrade.
6. Summary
Nano touch blackboard and teaching all-in-one machine are both important core products in the current educational information environment. For educational equipment purchasers, if they want to choose better products, they must rationally and comprehensively consider various factors. They must not blindly follow the trend or simply stick to the price economy. "Careful consideration of the future" is the best policy.
