It has to be said that in the past, the multimedia display system composed of a combination of traditional projectors and computers was widely used in school teaching, corporate meetings or business applications, which improved the speed and intuitiveness of information dissemination. With the advancement of science and technology, people are constantly pursuing new things, and the shortcomings of projectors in the use process are gradually revealed. During the use of the projector, the problem that users cannot interact with the computer system in a more intuitive and clearer way is becoming more and more serious, and it can no longer meet the needs of people.

The educational all-in-one machine adopts the appearance design of the whole machine, which integrates the functions of various equipment such as computer, TV, audio, and electronic whiteboard. The installation is simple and convenient, and does not take up too much space. However, the previous multimedia projection teaching equipment has too many supporting facilities, installation is troublesome, wiring is complicated, operation is cumbersome, and the equipment investment cost is much higher than that of the education all-in-one machine.

All functional applications of educational all-in-one products will have a core application software, that is, interactive electronic whiteboard software. Its functional application is similar to the traditional blackboard, but it is more advanced and has more functions than the blackboard. More importantly, the application of the infrared/capacitance education all-in-one machine has solved the problem of dust pollution caused by the chalk brought by teachers and students using black and white chalk in the past, and created a dust-free, pollution-free technology and green education for teachers and students. learning environment.

As times change, so do the methods that enable the dissemination of knowledge. The traditional teaching mode cannot meet the learning needs of students in the new era, and cannot improve students' learning enthusiasm and interest. The application of educational all-in-one machine, with its unique multimedia technology and human-computer interaction touch function, presents knowledge to learners more vividly and intuitively in a new way, improves their learning enthusiasm and stimulates their learning enthusiasm .

Compared with the problem of being greatly affected by light in the previous projection teaching, the educational all-in-one machine does not have this problem at all. The resolution of the LCD screen of the large-size touch all-in-one machine is as high as 1920*1080, the picture is clear, the color is true, and the viewing angle is 178 degrees, so that every student in the classroom can clearly see the displayed content, thereby attracting students Attention, to achieve the purpose of improving teaching efficiency.

Facing the educational all-in-one machine with so many advantages, how can the projector not be eliminated? I believe that in the near future, although the application of projectors will definitely exist, in multimedia fields such as school teaching and corporate conference training, touch all-in-one machines will completely replace projectors.
