People who have used smartphones will know that multi-touch is a very smart technology. Usually, when we browse the web and pictures, we often have to zoom in on some areas to see clearly. It is very easy and comfortable. However, many people only think that multi-touch is limited to zoom in and zoom out functions, but in fact, zoom in and zoom out is just the basic application of multi-touch.
At present, the multi-touch screen-body machine produced by WINHI has applied multi-touch to many aspects, changing or innovating more operation modes to a certain extent. At present, the most widely used multipoint touch screen all-in-one machine in the market includes infrared touch screen all-in-one machine and capacitive touch screen all-in-one machine. The touch screen is also an important factor that directly affects the touch-screen all-in-one machine quotation. Capacitive screens and infrared touch screens are used in all walks of life because of their agile touch and accurate positioning, while other touch screens are difficult to be widely used in some fields due to constraints of various factors. So in the purchase of touch query all in one machine, capacitive touch or choose the best-infrared touch screen?
Now the infrared touch all in one machine can do the screen all around the edge, the same size with black edge touch all in one machine display area is larger, more beautiful, and there is no limitation in the use of size. All-in-one touch capacitance touch screen click faster than infrared touch screen machine when the finger touches the surface of the glass, the fingers of electric current and toughened glass at the bottom of the metal layer, contact capacitance will change, then connected oscillator frequency change, also by frequency variation strength of different can accurately position the touch. No strong magnetic field interference, under normal circumstances, the capacitor touch screen all-in-one machine will not appear offset, positioning inaccurate phenomenon. Relatively speaking, the larger the size of the capacitive touch screen all-in-one machine, the higher the price, and because of the technical difficulties, the current capacitive touch screen all-in-one machine in the size of the maximum limit of 65 inches.
