The quality of the teaching touch all-in-one can be seen from the following aspects:
1. Host configuration
Host configuration is a basis for the quality of teaching touch all-in-ones, because no matter how good software is, good hardware is required, otherwise it will be difficult to exert the strongest function. Therefore, the choice of product host configuration is also very important, usually including CPU , Chips, memory, hard drives, industrial motherboards, etc.
2. LCD screen
The LCD screen is one of the important components in the teaching touch all-in-one machine, and its quality can greatly affect the quality of the teaching touch all-in-one 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 dotted screen.
3. Touch screen
The touch screen, like the LCD display, is the most important part of the teaching touch all-in-one. The touch screen can be divided into four types: capacitance, resistance, optics, and infrared. Among them, infrared touch screen is currently the most popular and easy to use. Screen, it can be touched with a finger, pen or any object that can block light.
4. Decoding board chip.
The quality of the decoder board chip used in the teaching touch all-in-one machine is related to the display effect of the teaching touch all-in-one machine. Because the decoding function of the decoder board chip is to support resolution and stability, if the resolution and stability of the decoder board chip are poor, then when we play files and videos, the display effect and stability will also deteriorate.
5. Power supply.
In the teaching touch 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, without a stable and durable power supply, the teaching touch all-in-one machine may suddenly power off during use. Such phenomena will not only affect the normal use of the device, but may also damage the hardware of the device and shorten the service life. Therefore, we can distinguish the quality of the teaching touch all-in-one machine through the stability and service life of the power supply.
