> With the rapid development of the industry, the manufacturers of teaching all-in-one machines are also increasing, and the quality of products is also uneven. When users purchase teaching all-in-one machines, how should we distinguish the quality of the teaching all-in-one machine?

>

> the quality of the teaching all-in-one machine can be seen from the following aspects:

>

>

>

> Touch screen

> touch screen is the same as LCD screen, they are all the most important parts of the teaching all-in-one machine. The touch screen can be mainly divided into four types: capacitance, resistance, optics and infrared. Among them, the infrared touch screen is currently the most popular screen for easy use, it can be touched with a finger, a pen or any object that can block light.

>

> Liquid Crystal Display

> liquid crystal display is one of the important components in the teaching all-in-one machine, its quality can greatly affect the quality of all-in-one teaching machine. Therefore, the user can judge the quality of the LCD screen by checking whether the LCD screen is brand new, whether it is an old screen, an old screen, or a dot screen.

>

> host configuration

> host configuration is a foundation for the quality of the teaching all-in-one machine, because the best software also needs good hardware support, otherwise, it is difficult to play the strongest function, so the host configuration selection of the product is also very important, usually including CPU, Chip, memory, hard disk, industrial control motherboard, etc.

>

>

> Decoding board chip

> the quality of the decoding board chip used in the teaching integrated machine is related to the teaching display effect of all-in-one machine. Because the decoding function of the decoding board chip is to support resolution and stability, if the resolution and stability of the decoding board chip are poor, then when we play files and videos, its display effect and stability will also deteriorate.

>

> power supply

> in the teaching all-in-one machine, the power supply is the most basic component. As a pillar supporting the normal operation of the learning touch all-in-one machine, there is no stable and durable power supply. During the use of the teaching all-in-one machine, there may be phenomena such as sudden power failure and crash, which will not only affect the normal use of the equipment, but also damage the hardware of the equipment and shorten the service life. Therefore, we can distinguish the quality of the teaching all-in-one machine through the stability and service life of the power supply.

>

> If you don't know how to choose the brand of teaching all-in-one machine, recommend the manufacturer of teaching all-in-one machine for you, as a professional touch all-in-one manufacturer with more than 10 years of rich production experience, Etel's teaching all-in-one machine has won high recognition from consumers for its excellent product quality and good service attitude.

>

> Today, the teaching all-in-one machine has been applied in more and more industries with its advantages of practicability, advancement, expansibility and handwriting convenience.

large interactive touch screen are required in the manufacture of almost every product and screen interaction large touch screen monitor is one of the most common machines.
