TCM08A Industrial touch screen touch features sharing
TCM08A The touch of the industrial touch screen uses the current induction of the human body to work. The industrial touch screen is a four-layer composite glass screen, the inner surface of the glass screen and the interlayer are coated with a layer of ITO(indium tin oxide), the outermost layer is a thin layer of silica glass protective layer, the interlayer of indium tin oxide coating as the working surface, four electrodes are led from the four corners, and the inner layer of indium tin oxide is the shielding layer to ensure a good working environment.
According to the working principle of the touch screen and the medium for transmitting information, the touch screen is divided into four types, which are resistance type, capacitive induction type, infrared type and surface acoustic wave type. Each kind of touch screen has its own advantages and disadvantages, to understand which kind of touch screen is suitable for which occasions, the key is to understand the working principle and characteristics of each kind of touch screen technology.
TCM08A When the finger touches the metal layer, due to the human electric field, the user and the industrial touch screen surface form a coupling capacitor, for high frequency current, the capacitor is a direct conductor, so the finger draws a small current from the contact point. The current flows from the electrodes on the four corners of the touch screen, and the current flowing through the four electrodes is proportional to the distance between the fingers and the four corners, and the controller obtains the position of the touch point through the accurate calculation of the ratio of the four currents.
1, TCM08A high resolution of industrial touch screen in the past, there are technical problems such as low resolution touch screen is limited, but with the continuous development of display technology, the transmission rate and resolution of industrial touch screen touch screen have been greatly improved. At present, 1080*1920 resolution can be achieved, and even higher.
2, touch sensitive industrial touch screen, support industrial gloves touch Industrial touch screen support capacitive and resistance two touch methods, but at present more capacitive touch, its touch sensitive, support highly intelligent identification, and support a variety of industrial gloves, medical gloves, wet touch and so on. And can enhance the explosion-proof function.
Industrial touch screen integrated machine compact design, low power consumption, active heat dissipation, quiet design, while industrial touch screen integrated machine is also configured with a highly reliable industrial power supply, can give industrial touch screen integrated machine protection in the case of overvoltage and overcurrent. Industrial touch screen is currently the display touch device used by many terminal products, generally we are looking for LCD screen manufacturers are best to find a set of display and touch screen can provide a company, because this can save a lot of problems.
If you have any questions or needs for industrial touch screens, TCM08A or are interested in how to integrate industrial touch screens into your business, you can turn to Step Control Technology.
