Now touch screens are used in a wide range of applications, and many electronics now use touch screens, for example: mobile phones that we use often are used to touch screens, but few people know what they do。
Touch screens are divided into two categories:
Capable touch screen
Interceptive touch screen
And the sense between them is different, and if you use a barrier-to-touch screen, you have to press it to react, but instead if you use a face-to-face screen, because it's a sensor through a human battery, like if you just have to touch the lord, and the screen is more sensitive than a resistance screen。
As shown below:
It's actually a sensor screen, it's made of four different layers of glass, and each layer of glass has a different function, and in the glass, they're coated with a guidance layer, and when we use this finger to touch our screen, it's a sensor。
This sense, because the body itself is an electric field, and then the touch layer is an electrical field, and when our mobile phone touches this touch screen, they create a coupling face, so that they form a conductor between them, and when they form a conductor, then the touch screen comes out with some electrical currents and is sucked away from our phone。
When this finger takes away our batteries, there's a four-angle current coming out of this touch screen, and the hand source of these electrodes and our human cell phones are proportional to the distance from the four-angle, so one of the controls inside will calculate the comparison of these four currents and calculate where the currents flow from, so that you can know that the touchpoint is in that position。
The accuracy of the ratio of this control to the current is still relatively accurate, with the accuracy being below 99 per cent and the speed of response being very large, less than 3 ms。
Structure of the ect screen
(1) single layer ito: oca glue, ito panels, panels, wires, circuit boards, glass protection
This screen is perfect because it's very expensive to make, and it's very good to see light, but its disadvantage is its vulnerability to interference
(2) one-sided double ito: protection of glass, oca, glue glass, ito1, ito2, base plate
This screen is very good, very good, very good quality, but the disadvantage is that production costs are high
(3) two-sided ito: protection of glass, oca, glass, ito, base plate
The advantage of this touch screen is that it's very good, and it's also resistant to static electricity, but the disadvantage is that it's more accessible to interference。
The three electric touch screens described above have their own strengths and weaknesses, and when used, you can choose to use them according to your actual needs。
The classification of sensory screens can be divided into two categories:
Surface capability
Pump-to-pump, which can be broken down into self-pump (which can achieve single dots + gestures) and the other is interactive (which can achieve multiple dots)
