With the rapid development of the all-in-one machine field, the number of manufacturers of all-in-one teaching machines is also increasing, and the quality of the products is also mixed with well-known brands. How should customers identify the quality of the all-in-one teaching machine when purchasing a teaching all-in-one machine? Several key components to teach you to choose properly.
The structure of the touch screen
Like the LCD screen, the touch screen is the most important part of the teaching machine. Touch screen can be divided into four types: capacitors, resistors, electro-optics, and infrared. Among them, infrared touch screen is the most fashionable practical display screen at this stage, which can be touched with a finger, a pen or any object that can block the light source.
The liquid crystal display is one of the key components of the teaching all-in-one computer, and its quality has a great impact on the quality of the teaching all-in-one computer. Therefore, customers can distinguish the quality of the LCD screen according to whether the LCD screen is newly upgraded, old display screen, old display screen or dot matrix display screen.
Server configuration of multimedia teaching machine
Server configuration is the basis of the quality of teaching all-in-one machine. No matter how good the mobile phone software is, it must also be suitable for good hardware configuration, otherwise it will be difficult to give full play to the strongest role. Therefore, the selection of commodity server configuration is also very important, generally including CPU, chip, running Memory, computer hard drives, industrial control motherboards.
In the teaching all-in-one machine, the switching power supply is the most basic component. The teaching all-in-one is the support for the normal operation of the learning and training touch all-in-one. If there is no stable and durable switching power supply, it is very likely that the power will be turned off suddenly, which will not only endanger the normal application of the machine and equipment, but also continue to Destroy the hardware configuration of machine equipment and reduce its service life. Therefore, we can distinguish the quality of the teaching all-in-one machine according to the stability and service life of the switching power supply.
Decoder chip in teaching all-in-one machine
The decoder chip used in the teaching all-in-one machine is associated with the teaching all-in-one machine to show the actual effect. Since the codec function of the decoder board chip is suitable for screen resolution and stability, if the screen resolution and stability of the decoder board chip are not very good, when you play the video file video, the decoder board chip shows the actual effect. and stability will decrease.
