The hardware composition of the touch all-in-one machine is mainly divided into three parts, namely the LCD screen, the touch screen and the computer host. In these aspects, the LCD screen determines whether the display resolution of the machine is high-definition, clear and not blurred; the computer host determines the overall 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 of 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, and the user only needs 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, I will 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 those requiring precision industrial control. Mainly used in industrial control sites, offices, homes and other public places with fixed users.
Capacitive touch screen: Since the capacitance varies with temperature, humidity, and grounding conditions, it has poor stability and is prone to drift. Afraid that the electromagnetic field will interfere or drift, it is not easy to use in industrial control places and interference places. It can be used for public information queries that require less precision; frequent calibration and positioning are required.
Infrared induction touch screen: low resolution, but not subject to current, voltage, electrostatic interference, suitable for use in harsh environmental conditions; suitable for various public places, offices and industrial control places that require low precision requirements. And it is suitable for the requirements of large-size touch screen devices, and is a practical type of touch screen at present.
Sonic screen touch screen: pure glass material, excellent light transmission, long life, good scratch resistance, suitable for all kinds of public places with unknown users. However, it is afraid of dust accumulation and oil pollution 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 touch screens, the infrared screen and capacitive screen are suitable for use in the touch query all-in-one product. Among them, the infrared touch screen is suitable for touch all-in-one products of any size due to its relatively mature technology and low cost, while the capacitive screen can only be applied to small products.
