6.5-inch 3-layer PET+ITO Film+ITO Glass Structure Digital Resistive Touch Screen for Industrial Control Machine
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 digital matrix resistive touch screen.
Dr Pan: Hello, Greg. Digital matrix resistive touch screen is being replaced by analog 4-wire and 5-wire resistive touch screen.
Dr Pan: The most vivid feature is multi-wire FPC.
Dr Pan: It is going to need two layers to achieve the touch function: Top sheet ITO film and Bottom sheet ITO glass. It is supposed that bottom layer is X electrode and top layer is Y electrode, anode end is 5.0 V and cathode end is 0 V.
Dr Pan: Every touch point in touch screen is corresponded with one wire in X electrode and another wire in Y electrode, that is why there are so many wires.
Dr Pan: However, analog 4-wire and 5-wire resistive touch screens can achieve the exactly same function as digital matrix resistive touch screen, and much cheaper.
Dr Pan: The latter is the more primitive,
Dr Pan: and the former is the newer and improved product.
Greg: Dr Pan, is digital matrix resistive touch screen still used in the practical application?
Dr Pan: Of course, it not only has all the merits of analog 4-wire resistive touch screen, but also is extremely accurate because one touch point is corresponded with one wire in X electrode and another wire in Y electrode.
Dr Pan: The phenomenon of deviation is not going to happen like analog resistive touch screen does.
Dr Pan: It is still used in industrial control machine because of the high quality requirements.
Greg: Thank you, Dr Pan. Now I got it.
Dr Pan: Welcome to contact us if you have any question.
