The hardware composition of the touch all-in-one machine is mainly divided into three parts, namely the LCD screen, touch screen and computer host. In these aspects, the LCD screen determines whether the screen display resolution of the machine is high-definition, clear and not fuzzy; the host computer determines the overall operating performance of the machine, and the data processing speed is fast but not fast; the touch screen, as the main medium for users to operate the machine, It affects the user’s operating experience on the machine. The advantage of the touch all-in-one machine is that it is very simple and convenient to operate. It does not need to use a traditional mouse and keyboard. Users only need to touch the screen to complete the operation. Therefore, the selection of touch screen is very important, which is directly related to the quality of user experience.
There are many types of touch screens on the market now, mainly including capacitive screens, resistive screens, infrared screens, and acoustic wave screens. These four types of touch screens are the mainstream of touch screen market applications. Next, give you a brief introduction to these four touch screens.
Resistive touch screen: excellent sensitivity and light transmittance, longer service life, not afraid of dust, oil and photoelectric interference, suitable for all kinds of public places, especially places that require precision industrial control. It is mainly used in public places for fixed users such as industrial control sites, offices, and homes.
Capacitive touch screen: Since the capacitance changes with temperature, humidity, and grounding conditions, its stability is poor and it is prone to drift. Fear of electromagnetic field interference or drift, it is not easy to use in industrial control places and interference places. It can be used for public information inquiries that require less precision; frequent calibration and positioning are required.
Infrared induction touch screen: low resolution, but not affected by current, voltage, static electricity, suitable for use under harsh environmental conditions; suitable for various public places, offices and industrial control places that do not require high precision. And it is suitable for the requirements of large-size touch screen equipment, and it is the most practical type of touch screen at present.
Acoustic screen touch screen: pure glass material, excellent light transmission, long life, good scratch resistance, suitable for various public places with unknown users. But it is afraid of dust and oil contamination for a long time, so it is better to use it in a clean environment. In addition, regular cleaning services are required.
Among the above four types of touch screens, infrared screens and capacitive screens are suitable for touch inquiry all-in-one products. Among them, the infrared touch screen is suitable for all-in-one touch products of any size because of its relatively mature technology and low cost, while the capacitive touch screen can only be used for small products, and the cost of large-sized products is too high and the price is not cost-effective.
