The LCD touch machine can be regarded as an information display, supporting the display equipment of machine to machine and human to machine interaction. Liquid crystal touch all-in-one machine is a set of advanced touch screen, industrial control, computer and other technologies as one of the equipment, we can use powerful functions to achieve information inquiry, fingerprint identification, scanning, reading information, printing and other services for the public equipment, as well as fingerprint attendance, card swiping, printing and other needs. The touch screen has multiple screens; Now liquid crystal touch all-in-one machine mainstream application has capacitive touch and infrared touch two kinds, BVS take you to understand these two kinds of screens.
Infrared touch technology has been very mature, touch sensitivity can also, plus the cost is not high, touch all-in-one machine has a lot of infrared. The disadvantage of infrared touch is that there are requirements for the application of the occasion, infrared touch is not suitable for the occasion of strong light, when there is direct sunlight on the touch surface above, the accuracy of the touch has a certain impact. Infrared touch is to analyze the position of the touch by blocking the infrared ray emitted by the infrared frame. As you can imagine, when there is dust, water droplets and other shielding will have an impact on the touch. Therefore, generally in the absence of strong light irradiation of indoor cleaning scene, choose to use infrared touch.
A capacitive touch screen can simply be viewed as a screen made up of four composite screens: the outer layer is a protective glass layer, followed by a conductive layer, the third is a non-conductive glass screen, and the innermost fourth is also a conductive layer. The innermost conductive layer is the shielding layer, which plays the role of shielding internal electrical signals. The middle conductive layer is the key part of the whole touch screen. There are direct leads at four corners or four edges, which are responsible for detecting the position of the touch points. Now with the gradual reduction of capacitor cost, as well as the larger and larger size of the capacitor, its high sensitivity, strong anti-interference ability, a wide range of use scenarios, small impact on the appearance of the machine and other advantages, capacitive touch at a fast speed to differentiate the market share of infrared touch.
Now the LCD touch machine technology and solutions have been mature; It can meet the application needs of different regions, different places and different users. To meet the needs of customers for intelligent society, provide life efficiency, and provide better conditions for the display and dissemination of information.
The above is about the difference between LCD touch all-in infrared touch and capacitive touch. If you have other questions, please pay attention to our company's website.
