Outsiders often misunderstand this kind of term, taking the common computer display screen as an example, it is only a kind of display screen, and its structure is basically the same as that of the mobile phone screen except for special models.
The display structure used by most computer monitors does not contain a touch screen and does not have a touch function, and this kind of display screen is classified as an output device and a display device;
The display screen with touch function, although it is still a display screen, has an additional touch function, and the screen structure layer responsible for providing the touch function is called the touch screen;
In the process of daily use, people will directly use "display" to depict the display screen, and "touch screen" is used to depict the display with a touch screen;
But in fact, this kind of display uses a "touch display", which provides output and imaging functions, and also includes touch functions, so many people misunderstand that it is attributed to output devices.

What is the technical principle of Hitec touch screen?
The touch screen senses the contact of our fingers because when the finger touches a specific direction on the screen, it is equivalent to sending a precise electronic signal to the screen. There are many types of contact screens, which are broadly divided into resistive contact screens and capacitive contact screens. Now the most widely used is "electricity...

The PLC and touch screen interact consistently
When the touch screen is connected with the PLC, in fact, the memory of the PLC is used, (the touch screen also has a small amount of memory, which is only used to store system data, that is, the screen, controls, etc.), the touch screen and the PLC communication is generally the master/slave contact, that is, the touch screen reads the data from the PLC, and the judgment is made in the display ...
