The whiteboard manufacturer talks about how a cost-effective electronic whiteboard is a good choice.

Whiteboard manufacturer: with the continuous development of national education, campus education is also facing the trend of modern information education. Campuses are also constantly introducing advanced educational equipment, expecting better and better classroom education. As a new educational equipment that is simple and effective, the interactive electronic whiteboard researched by our company has brought a new look to campus education.

Now the application of all-in-one touch machines is more and more extensive. There are more and more whiteboard manufacturers and vendors. Many customers often cannot choose when they need to buy, because they do not know what kind of all-in-one touch machine has a higher cost performance. The key is to choose a manufacturer with good cost performance. As a multimedia device applied in education, meetings and other fields, the all-in-one machine needs to have characteristics such as a more durable touch screen, fast and accurate touch writing response, a slim body and space saving, and simple and easy-to-use equipment. At present, there are two main application types of all-in-one machines: one is the optical touch machine, and the other is the infrared touch machine. The all-in-one optical touch machine is made with the advanced optical imaging technology of the time. Compared with the all-in-one infrared contact machine, its contact function, stability function and resource utilization function are more excellent.

Whiteboard manufacturer: can a damaged electronic whiteboard still be used?

The current status of three kinds of electronic whiteboards:

(1) Optical electronic whiteboard: it can still be used normally after the board surface is damaged by impact.

The working principle of the optical whiteboard is: select the left and right CCD cameras in the upper frame to emit light, and the reflective strips on the left and right lower frames reflect to form an optical matrix, realizing correct positioning. There are no electronic components such as infrared receiving tubes on the left and right lower frames, and it is not afraid of scratches. Therefore, even if the board surface is scratched or damaged, normal operation will not be affected.

(2) Infrared electronic whiteboard: it can also be used normally after the board surface is damaged by impact.

The infrared electronic whiteboard is based on the principle of infrared sensing technology. A pair of infrared emitting and receiving devices are installed around the electronic whiteboard. The infrared rays between the emitting tube and the receiving tube form an infrared network, which covers the outer surface of the electronic whiteboard. According to the principle of this technique, even if the board surface of the infrared electronic whiteboard is damaged, as long as the light tubes on the four sides of the electronic whiteboard frame are not damaged and there is no protruding foreign object on the board surface, the electronic whiteboard can be used normally.

(3) Electromagnetic electronic whiteboard: it cannot be used normally after the board surface is damaged by impact.

The electronic whiteboard consists of a receiving coil film placed horizontally and vertically using the electromagnetic induction technique and a pen that can emit electromagnetic waves. The size of the film is the same as the size of the flash area. According to the working principle of the electromagnetic electronic whiteboard, when a part of the board surface is damaged by impact, the coil cannot sense the electromagnetic wave, and then cannot be positioned correctly. Therefore, the board surface of the electromagnetic electronic whiteboard cannot be used normally after being damaged by impact.
