What is Analog 5-Wire Resistive Touch Screen?
The Analog 5-Wire Resistive Touch Screen is a highly advanced touch screen technology that offers exceptional precision and responsiveness. It is known for its unique 5-wire FPC feature, which sets it apart from other touch screen technologies.
Dr Pan: Welcome to DISPLAY Museum. I am Dr Pan, the curator of Museum.
Greg: Hello, Dr Pan. I am Greg. I came here to learn about analog 5-wire resistive touch screen.
Dr Pan: Hello Greg. Analog 5-wire resistive touch screen is the most advanced, reliable and fastest touch technology so far. The most vivid feature is 5-wire FPC.
It is going to need two layers to achieve the touch function: Top sheet ITO film and Bottom sheet ITO glass. ITO film that only serves as detective probe is still working even if it has been slightly damaged. Both X and Y electrodes are on the ITO glass, and X+, X-, Y+ and Y- are located in the four corners. It is supposed that anode end is 5.0 V and cathode end is 0 V. When we touch the surface of the screen, the controller can get 4 values in the 4 corners. The contacting positions can be calculated since the values in the 4 corners are noted.
Greg: Dr Pan, since you said analog 5-wire resistive touch screen is so great, can I say that it is the best touch screen you have ever seen?
Dr Pan: Not really. Every coin has two sides. It can be used in the hostile environment: dust, humidity, greasy dirt. High resolution and extremely long serving time. It is the best choice for ATM, industrial machine, POS machine, ticket machine, medical equipment, copy machine, etc. Even if the ITO film is slightly damaged, it can still be working. It perfectly solves the short serving time problem of analog 4-wire resistive touch screen.
But it isn’t doing very well in both user experience and light transmittance. It requires a touch point correction after some time of serving.
Greg: Thank you, Dr Pan. Now I got it.
Dr Pan: Welcome to contact us if you have any question.
