Commonly used touch screen integrated machine which screen material is good, capacitance or infrared touch?
Touch screen is also an important factor affecting the price of the touch screen integrated machine. The touch screen on the market has resistive screen, electromagnetic screen, capacitive screen, infrared touch screen, etc. the capacitance screen and infrared touch screen are sensitive to location and applied to all walks of life. Other touchscreens are difficult to be widely used in various fields due to various factors. So when choosing a touch and query machine, is it better to have a good touch or choose an infrared touch screen?
Now the infrared touch screen integrated machine has been able to achieve no black edges around the screen, and the same size black edge touch one machine displays larger and more beautiful appearance. And it has exceeded 100 inches in size.
The touch touch speed of the capacitive touch screen is faster than that of the touch screen. When the finger touches the surface of the glass, the capacitance of the fingers will change with the contact of the metal layer below the toughened glass, and the frequency of the oscillator will change. Without the interference of a strong magnetic field, under normal circumstances, the capacitive touch screen machine will not be offset or positioned inaccurately. The larger the size of the capacitive touch screen, the more expensive the price. And because of the difficulty of technology, the 55 inch capacitive touch screen integrated machine is rare in the market.
Because the capacitive touch panel machine is difficult to produce in large size, not every manufacturer has the ability to produce a capacitive touch screen integrated machine with stable performance. So the answer given on the market is the selection capacitance touch screen integrated machine less than 32 inches, and the above choice of infrared touch screen all-in-one.
The working principle of the capacitance screen: the touch screen is the best protection against the scratch of the siliceous earth. It is very good against scratching. But afraid of fingernails or hard objects knocking, knocking out a small hole will hurt the interlayer ITO. Whether it is injure sandwich ITO or install the transportation process and the ITO layer on the inner surface, the capacitive screen can not work properly.
Multi touch: if you have used iPhone, you will know that multi touch is a very useful and fun thing: when you browse the web, you often need to enlarge some area to see clearly, and when you look at the picture, it is also very useful. Of course, without this function, human beings are the same to adapt to and achieve their goals. Just like mobile phones without touch function, they still get on the Internet. Of course, simplicity and comfort are different. It's the same as eating meat and eating vegetables.
Many people think that multi touch is limited to zoom in and out. Actually, zooming is just one example of the practical application of multi touch. With multi touch technology, how to use it can expand indefinitely. Programmers can apply multi touch to many aspects, and change or innovate more ways of operation to a certain extent. The typical application is to play the piano on hard glass. If you turn your screen into a keyboard, it's still fun to fool the little girl. Another typical example is the PS simulator on Apple's mobile phone, which realizes the simultaneous input of directional keys and other buttons through multi touch technology.
