With the continuous advancement of science and technology, traditional blackboard chalk and multimedia classrooms are gradually being phased out in the field of education and teaching. The new generation of electronic touch devices - educational all-in-one machines, with their own characteristics and advantages, have become the mainstream application devices for education and teaching.

The educational all-in-one machine is mainly composed of a LCD screen, a touch screen, and a computer host, with unique human-computer interaction functions. Therefore, teachers and students can freely write on the screen of the machine, which is very convenient and fast, without dust pollution. In addition, in order to meet the application needs of different users, educational all-in-one machines include embedded, wall mounted, and mobile models.

Due to the increasing demand for applications, there are more and more brands of educational all-in-one machine manufacturers, with uneven quality and numerous brands. Many unscrupulous merchants, in order to seek profits, pass off inferior educational all-in-one machines as good and sell them to consumers who are unfamiliar with the products, causing a lot of trouble for many users.

So, what aspects can be used to judge the quality of educational all-in-one machines?

1、 Power supply

In multimedia teaching touch all-in-one machines, the power supply can be said to be a crucial component because it is the pillar that supports the normal operation of the touch all-in-one machine. Without it, there is no way to work. Therefore, we can distinguish the quality of multimedia education all-in-one machines based on the stability and service life of the power supply.

2、 Touch screen

Multimedia teaching touch all-in-one machine, like LCD screen, is an important part of multimedia teaching touch all-in-one machine. Touch screens can be divided into four types: capacitive, resistive, optical, and infrared. Among them, infrared touch screens are currently the more popular screens, which can be touched by fingers, pens, or anything that can block light.

3、 Decoding board chip

The quality of the decoding board chip used in the multimedia teaching and education all-in-one machine will directly affect the display effect of the multimedia teaching touch all-in-one machine. Because the decoding function of the decoding board chip supports resolution and stability, if the resolution and stability of the decoding board chip are poor, the display effect and stability of the decoding board chip will also deteriorate when playing files and videos.

4、 LCD screen

LCD display screen is one of the important components of multimedia teaching touch all-in-one machine, and its quality can greatly affect the quality of multimedia education all-in-one machine.

5、 Host performance

The educational all-in-one computer host is one of the core components, and its configuration parameters directly affect the overall operational performance of the educational all-in-one machine, while the quality and brand of accessories will affect the service life of the computer host.

A high-quality and powerful educational all-in-one machine that can maintain efficient operation for a long time and provide convenient services for teachers and students during use.
