What are the functions of electronic whiteboard brands?

It's funny below, Dalian Boshuo, it's Jida Boshuo.

Now the technology of whiteboard on the market can be divided into several types: 1. Ultrasonic technology, which is basically invisible now. 2. Pressure-sensitive technology, the technical principle is made of two layers of conductive film, and you must use force when writing, but this kind of whiteboard is very afraid of scratches, and once scratched, it cannot be used.

3. Electromagnetic technology, this kind of whiteboard is relatively cheap, but because it must be used with a special pen, if the pen is lost, it cannot be used. 4. Infrared technology, this kind of tabula rasa is now used a lot on the market, and it is also very suitable, but because the maintenance is more troublesome and there has been no breakthrough in technology, it is still very good overall. 5. Optical technology, the most advanced tabula rasa technology, has a new breakthrough in technology, it has upgraded some functions and technical parameters on the basis of infrared technology, optical technology is to support multi-point, double writing, and optical tabula rasa is also very suitable.

There is also a Dalian Ph.D. degree

Ultrasonic infrared technology.

The others are basically infrared, pressure sensitive, and electromagnetic.

Ultrasonic infrared technology is only wonderful and my family has it

Dear, you missed a very important company, Huiguan Optical Electronic Whiteboard. As the only listed company in the domestic whiteboard industry, we say that there is no pressure. ****300282。You can check it yourself.

There is also the brand of China Television Co-creation.

Hello, the whiteboard is the surface of the board written with a water-based pen, and the electronic whiteboard is the current advanced interactive equipment that needs to be used with computers and projectors.

The technology of electronic whiteboard is divided into infrared touch technology and electromagnetic pressure sensing technology. The electronic whiteboard with infrared technology can be written with fingers or any opaque object, and the electromagnetic electronic whiteboard requires a special electromagnetic induction pen to write and operate.

The writing operation of the electronic whiteboard is completely synchronized with the computer, which is equivalent to replacing the mouse with a finger or pen, and the display of the projector replaces the display to achieve the role of human-computer interaction.

Tengya electronic whiteboard.

Electronic whiteboard, the full name of interactive electronic whiteboard, can be referred to as interactive whiteboard, intelligent whiteboard, electronic whiteboard, and sometimes directly referred to as whiteboard. The difference from the ordinary whiteboard is that it needs to be connected to a computer to use, and the pen in the software can be used instead of a real pen teaching. And the supporting software is powerful.

The whiteboard generally refers to the whiteboard used in ordinary office teaching, which is erased by ordinary pen writing.

The whiteboard is written with an ordinary pen, and the electronic whiteboard is written with an electronic pen, so when erasing the handwriting, the way is different

Whiteboard and electronic whiteboard are just a name, some people call electronic whiteboard whiteboard, in order to save trouble. But an ordinary tabula rasa can't be called an electronic tabula rasa.

Generally speaking, a whiteboard is an ordinary whiteboard, which is an ordinary whiteboard that is written with a water pen and can be erased with a board eraser, without touch function, circuitry, etc.

Electronic tabula rasa is divided into a variety of technology whiteboard pressure-sensitive electronic tabula rasa, infrared electronic tabula, electromagnetic electronic tabula, optical electronic tabula rasa, they have interactive functions, to be used with projectors and computers. You can touch the electronic whiteboard to control the computer. At this time, the electronic whiteboard is actually a peripheral device of the computer, which can be said to be another touch screen of a computer.

Hope it helps.
