What is the difference between a four wire resistor touch screen and a five wire resistor touch screen。
The main differences between four-wire resistive touch screen and five-wire resistive touchscreen are reflected in the following aspects:
1. Sensitivity and lifespan: The five-wire resistive touchscreen has higher sensitivity and a longer lifespan compared to the four-wire resistive touchscreen. This is mainly due to the internal structure and material design of the five-wire resistive touchscreen, which maintains better performance and stability during use.
2. Internal structure: The touch layer materials and installation structures of the five-wire resistive touchscreen differ from the four-wire resistive touchscreen. The five-wire resistive touchscreen applies voltage fields in two directions through a precise resistor network on the conductive working surface of the glass, while the outer nickel-gold conductive layer serves only as a pure conductor. In contrast, the four-wire resistive touchscreen requires two layers to measure the X and Y axes.
3. Durability: The five-wire resistive touchscreen excels in durability, maintaining its performance after 35 million finger touch experiments. Comparatively, the maximum touch count of the four-wire resistive touchscreen is 1 million times, and it can only withstand 100,000 stylus operations.
4. Design flexibility: The five-wire resistive touchscreen allows for high-end designs such as flat, spherical, and cylindrical shapes, while the four-wire resistive touchscreen cannot achieve spherical designs.
5. Resolution accuracy: Although the accuracy of resistive touchscreens mainly depends on the precision of the A/D conversion, the five-wire resistive touchscreen offers superior resolution accuracy compared to the four-wire resistive touchscreen.
However, despite the superiorities of the five-wire resistive touchscreen in multiple aspects, its higher cost also results in a generally higher selling price. In contrast, the four-wire resistive touchscreen is favored by some users due to its lower cost.
Overall, the four-wire resistive touchscreen and the five-wire resistive touchscreen each have their unique characteristics and applicable scenarios. Users can choose between them based on their actual needs.
