In life, we often come into contact with touch screens, and many people will regard the human-machine interface as a touch screen, in a strict sense, there is a fundamental difference between the two.
"Touch screen" is only the hardware part that may be used in human-machine interface products, and is an input device installed at the front end of the display screen instead of the mouse and keyboard. A human-machine interface product is a human-computer interaction device that includes hardware and software. In the industry, people often refer to human-machine interface products with contact input function as "touch screen", but this is unscientific. Touch screen is people's popular name for "human-machine interface with contact function"! A real touch screen is just "a piece of clear glass that can be touched and operated by hand"! Can be used in place of a mouse. Modify the knowledge of human-machine interface
1. The industry of human-machine interface products: connect programmable manipulators (PLC), frequency converters, DC governors, appearances and other industrial control equipment, use the display screen to display, through the input unit (such as contact screen, keyboard, mouse, etc.) to write operation parameters or input operation commands, to realize the interaction of human and machine information digital equipment, composed of hardware and software. HMI is the abbreviation of Human-Machine Interface.
2. Composition and operating principle of human-machine interface (HMI) products
The human-machine interface product is composed of two parts: hardware and software, and the hardware part includes a processor, a display unit, an input unit, a communication interface, a data storage unit, etc., during which the function of the processor determines the function of the HMI product and is the core unit of the HMI. Depending on the product level of the HMI, the processor can be selected as an 8-bit, 16-bit, and 32-bit processor. HMI software is generally divided into two parts, namely the system software running in the HMI hardware and the screen configuration software running under the PC Windows operating system (such as JB - HMI screen configuration software). Users must first use the HMI's screen configuration software to create "engineering files", and then download the prepared "engineering files" to the HMI's processor through the serial communication port of the PC and HMI products.

The driving principle of the capacitive touch screen - Hitech
1. Projective capacitive contacts
Although the basic structure and working principle of a projected capacitive contact screen is the same as that of a four-wire impedance film, the projected capacitive impedance film does not go through the contact field, but captures the change in capacitance between the electrodes. Generally speaking, when using the form of a capacitive sensor, it can be ...

Resistive screen and capacitive screen of industrial tablet PC - Hitech
There is a difference in skills
The use of capacitive screen skills is later than that of resistive screens, and the skills are more advanced than resistive screens, and the price is naturally more expensive. This is what we often see, the same equipment of industrial tablet PCs, in terms of price, but there is a big difference, part of which is because of the difference in screens.
