One of the technologies we see becoming a factory standard with many devices, over a vast array of industries, is the resistive touch screen. Countless electronics have this tech integrated into them. Machines in hospitals, conveyor systems in factories, soda dispensers at a fast food restaurant, and ATMs at a gas station are common places to find these screens.
What makes resistive screens so popular? There are a number of answers to that question. To consider the benefits provided by these screens and why they appeal to electronics designers, we need to first get a better idea of how they work.
Resistive screens are computer displays comprised of multiple layers. The top layers consist of a polyester coversheet and conductive coating. Further in one finds insulating spacers followed by a resistive coating. Lastly, is a glass substrate or acrylic backing panel.
When pressure is applied to the top coversheet, the layers of the device compress completing a circuit. This sends a signal to a controller which, in turn, interprets where on the X and Y axis of the screen the device was touched. This is how the device knows where it was pressed and relates that information to the image data that was displaying there at the time.
Resistive touchscreens are popular, in part, due to their ability to interface directly with displayed information. No keyboard or mouse is involved. There are no separate buttons to push. People using a device with a resistive touchscreen can simply touch the image that is displaying information relevant to the task they wish to perform, directly.
This is why stores are using large screen displays with products showing. Interested shoppers can click on an image of the product that catches there interest and see more images, videos, or other information available on the device. See something you like, just press the image to learn more about it.
The ease of use makes these devices quite popular. Using displays with touchscreens creates an intuitive process that is easy to teach and fast to learn. It can also streamline switching between tasks and information thus, improving efficiency.
Exposed glass is prohibited in certain food industries. Fortunately for these industries, most resistive touchscreens offer a display that complies with the regulation of not having exposed glass.
Another reason resistive touchscreens are favored for many electronics is that the technical components take up very little space. Sure, large screens can make use of this technology but, so can smaller devices. These screens are quite thin and weigh very little compared to other types of screens or monitors. This feature allows a wide array of implementation in an equally varied number of electronics.
Companies appreciate that signatures can be collected via electronic device. Rather than gathering and having to store a vast collection of paper, a business can have employees and customers sign documents digitally. This is something that just wouldn't be available on the scale it's currently on without a touchscreen.
So, these are the reasons resistive touchscreens have been flooding the market. They offer a lot of benefits like being lightweight and intuitive. Their presence in so many industries really showcases the value of resistive touchscreens.
