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 3-layer resistive touch screen.
Dr Pan: Hello, Greg. There are two types of 3-layer resistive touch screens.
Dr Pan: Option 1, the second and third layers are functional layers and the touch function can be achieved by them; the top layer is the decorated layer and the silk-screen is painted on it. Actually, there are 7 layers in the 3-layer resistive touch screen. The 3 layers(decorated layer, two functional layers) are the main structure.
Dr Pan: From top to bottom, decorated layer, OCA, ITO bear layer1, ITO layer1, double-sided tape, ITO layer2 and ITO bear layer2.
Dr Pan: It looks good because of the silk-screen, although it gets a bad influence on touch experience and light transmittance.
Dr Pan: Option 2, the first and second layers are functional layers; the bottom layer is the supporting layer and it can increase the strength of the entire panel. There are also 7 layers in this 3-layer resistive touch screen. 3 layers(two functional layers and supporting layer) are the main structure.
Dr Pan: From top to bottom, ITO bear layer1, ITO layer1, double-sided tape, ITO layer2, ITO bear layer2, OCA and supporting layer.
Dr Pan: It is usually used on the products which have high strength requirements.
Greg: Thank you, Dr Pan. Now I got it.
Dr Pan: Welcome to contact us if you have any question.
