Popular science: What is a smart blackboard in the classroom?

The emergence of smart blackboards?

In the traditional teaching model, "blackboard + chalk" is almost a perfect pair, showing students valuable knowledge, and it is also what 

teachers use most in teaching. As a carrier of knowledge, even in the very difficult educational background of China in the last century, 

there must be a blackboard in the classroom. It can be seen that the blackboard plays an important role in traditional teaching.

With the rapid development of technologies such as the Internet, 5G, artificial intelligence, and electronic technology, in modern teaching 

and education, educational equipment such as smart blackboards and electronic whiteboards have gradually appeared on the stage.

So, what is a smart blackboard?

Smart blackboards usually use capacitive touch or infrared touch technology to combine traditional blackboards with multimedia devices 

to enable free switching between blackboard writing and media applications. It not only meets the needs of ordinary chalk blackboard 

display, but also facilitates teachers to display courseware, student homework and other audio and video images, seamlessly connects the 

traditional teaching blackboard and intelligent interactive experience, and meets the needs of classroom interactive teaching.

Why are smart blackboards so useful?

Why are smart blackboards highly practical, low in wear and tear, and long in life? Let’s take Qunmao Display’s smart blackboard as an 

example. The smart blackboard itself has special functions such as precise touch and diversified writing, and Qunmao Display's smart 

blackboard uses nanotechnology to elevate the practicality of the smart blackboard to a higher level. Let’s briefly introduce the technology 

used by Qunmao Smart Blackboard.

[Nano capacitive touch technology]

It uses nanoscale capacitive touch technology to achieve precise touch, extremely fast response, and can reduce interference and accidental 

touches. Nanotouch is a grid matrix layer formed by nanowires inside the touch film. Each matrix unit can sense the touch of a human finger. 

Each touch will cause a change in the current of the matrix unit, thereby achieving precise touch.

【Smart LCD Technology】

First of all, it uses anti-glare high-definition glass, intelligent high-definition display, DC dimming technology, one-click blue light eye 

protection, etc. to eliminate stroboscopic flickers and protect students' vision.

[Full-fitting 4K display technology]

It adopts full lamination technology, 4K high-definition display, more realistic pictures, stronger sense of presence, 178° wide viewing angle, 

and no parallax in writing.

In addition, Qunmao Display's smart blackboards are also riot-proof, waterproof, and anti-corrosion, which greatly reduces man-made losses 

to the product.
