Performance judgment mode of touch all-in-one machine
There are more and more manufacturers of touch all-in-one machines in the market. Of course, there are deviations in quality. So, for me, how to buy high-quality products at z preferential price? What are the main factors that determine the quality of the touch all-in-one machine?
The touch all-in-one machine is a combined product, which is composed of host configuration + LCD panel + touch panel.
Then, the quality of the touch all-in-one machine also depends on these three parts.
Host configuration, motherboard, brand motherboard, industrial control motherboard and various interfaces of industrial control motherboard have various functions, but it may be DIY. Is the performance of this motherboard compared with the brand motherboard?
Including CPU memory, hard disk, power supply, etc. the brand is not necessarily good, but the brand is relatively guaranteed.
LCD panel: in order to lower the price and make more profits, some bad operators make touch all-in-one machines with TV refurbished panels. This touch all-in-one machine is really cheap, but there are many after-sales service problems.
The touch all-in-one machine is not a laptop. If there is a problem, you can take out your bag and go to after-sales service. Our touch all-in-one machine weighs 100 kg. If there is a problem, we can't solve it by ourselves. Sending it for repair is also a problem. If you buy a cheap LCD touch all-in-one machine, you must be prepared for this after-sales service.
Touch screen: the touch screen is divided into several main touch modes, such as capacitor, resistance, optics and infrared, among which infrared is the most popular touch mode in the market.
Infrared touch is divided into true touch and false touch. True point infrared touch, no drift, no deviation, continuous circle. On the contrary, false touch will lead to breakpoints and drift. Although not very clear, but the use of various errors will annoy you!
