What is 4-Layer Resistive Touch Screen ?

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 4-layer resistive touch screen.

Dr Pan: Hello, Greg. Regarding 4-layer resistive touch screen, the middle two layers are functional layers and the touch function can be achieved by them; the first layer is decorated layer and the silk-screen is painted on it; the bottom layer is supporting layer and it can increase the strength of the entire panel.

Actually, there are 9 layers in 4-layer resistive touch screen. The 4 layers mentioned above (decorated layer, two functional layers and supporting layer ) are the main structure.

From top to bottom, decorated layer, OCA1, ITO bear layer1, ITO layer1, double sided tape, ITO layer2, ITO bear layer2, OCA2 and supporting layer.

Greg: Dr Pan, from my experience, I can barely see any 4-layer resistive touch screen on the market, why?

Dr Pan: It is true that it is rarely used because it is too costly and is being replaced by capacitive touch screen.

Greg: Thank you, Dr Pan. Now I got it.

Dr Pan: Welcome to contact us if you have any question.

Describing the features of 4-layer resistive touch screens

A 4-layer resistive touch screen is a type of touchscreen technology that uses two layers to detect touch input from a user. The middle two layers are functional layers that enable touch functionality, while the top layer is the decorated layer where the silk-screen is painted, and the bottom layer is the supporting layer that strengthens the entire panel. In total, there are 9 layers in a 4-layer resistive touch screen, including OCA1, ITO bear layer1, ITO layer1, double sided tape, ITO layer2, ITO bear layer2, OCA2, and supporting layer, in that order from top to bottom.

Despite its complex structure, 4-layer resistive touch screens are rarely seen in the market due to their cost. They require multiple layers of conductive material to be applied in a precise manner, which requires additional production steps and materials. This makes them more expensive compared to capacitive touch screens, which only require a single layer of conductive material, making them more cost-effective.

Knowing the advantages and disadvantages of 4-Layer Resistive Touch Screen

However, despite their higher cost, 4-layer resistive touch screens offer unique advantages in terms of accuracy and durability. They are commonly used in industrial and medical applications where the screens are subjected to harsh conditions and require precise input.

In contrast, capacitive touch screens are becoming more prevalent in the market due to their lower cost and ease of use. They work by detecting changes in the electromagnetic field caused by a conductive object, such as a finger or stylus, and can be operated with a light touch. This makes them ideal for consumer electronics such as smartphones, tablets, and laptops.

While 4-layer resistive touch screens are less common in the market, they still have a place in specialized industries that require high accuracy and durability. As technology advances, it will be interesting to see how the demand for 4-layer resistive touch screens evolves and whether they will continue to be used in these specialized industries.

Overall, the choice between a 4-layer resistive touch screen and a capacitive touch screen ultimately depends on the specific needs of the user. If accuracy and durability are a priority, a 4-layer resistive touch screen may be the better choice. However, if cost and ease of use are more important, a capacitive touch screen may be the way to go.
