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, but zoom in and zoom out is just the basic application of multi-touch. At present, multi-touch all-in-one machine produced by Zhongyu Display has applied multi-touch to many aspects, changing or innovating more operation modes to a certain extent.
And application on the market at present most touch all-in-one and capacitive touch screen camera with infrared touch screen machine, touch screen and offer the important factors that directly affects the touch screen machine, capacitance screen, and infrared touch screen by touching agile, accurate positioning and be applied to all walks of life, and other constraints due to various factors, the touch screen used in some areas, It is difficult to be widely used. 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 around the screen without black 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 yu display infrared touch all in one machine has broken through to 110 inches.
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 is the size of the maximum limit of 65 inches.
Due to the technical difficulty of capacitive touch screen all-in-one machine with large size, and not every manufacturer has the strength to control the stability of touch performance, it is recommended to choose capacitive touch screen all-in-one machine with 55 inches or less, and infrared touch screen all-in-one machine with 55 inches or more.
