Nano blackboard and all-in-one teaching machine: Which one is the best choice for education?

In today's education field, multimedia teaching has become the mainstream and development trend. When many colleges and universities 

purchase multimedia equipment, they often face the problem of choosing nano smart blackboards and intelligent teaching all-in-one 

machines. Both are interactive devices that integrate computer, display, audio and other functions, but they have significant differences 

in functional characteristics, imaging clarity, cost of use, application environment and convenience. This article will compare the two 

devices in detail to help users make a more informed choice.

First of all, from the perspective of functional characteristics, the interaction principles of nano smart blackboard and teaching 

all-in-one machine are different. The all-in-one teaching machine uses infrared touch technology, while the nano smart blackboard 

uses improved capacitive touch technology, namely nano touch. The nano blackboard achieves touch sensing through the internal 

nano touch film and does not require the transmitting/receiving lines of the infrared screen, so it can be mimicked and flat and look 

the same as an ordinary blackboard. At the same time, the nano blackboard retains the chalk writing function of the traditional 

blackboard, which is an indispensable part of teaching.


Secondly, in terms of imaging clarity, both use 2K high-definition display technology to ensure clear images and full colors. 

However, all-in-one teaching machines have shortcomings such as large radiation and dazzling screens in integrated machine 

teaching, which have a certain impact on vision. Nano blackboards perform better in this regard. Nano coatings are added to 

their surfaces, which can filter 80% of harmful light and effectively protect users' vision.

Furthermore, the cost of use is also an important issue that users are concerned about. When first purchased, the price of a nano 

smart blackboard of the same size is slightly higher than that of an all-in-one teaching machine, but with the mass production of 

large-size touch screens, the price gap will gradually narrow. In practical applications, the service life of the nano smart blackboard 

exceeds 50,000 hours, while the teaching all-in-one machine has a service life of approximately 40,000 hours. Therefore, users 

should consider factors such as purchase cost, service life, and application environment when choosing.


In terms of application environment, the all-in-one teaching machine is suitable for interactive modes that do not require chalk

 writing, while the nano smart blackboard has both chalk and touch screen interactive functions, which can meet more diverse 

teaching needs.

Finally, from the perspective of convenience, although both products integrate display and touch functions and are relatively 

easy to install and debug, the nano smart blackboard is more convenient to use and maintain. All-in-one teaching machines 

usually adopt a push-pull blackboard design, which increases the complexity and physical consumption of teachers' classes. 

The modular design of the nano smart blackboard makes maintenance and upgrades easier.
