Surface capacitive is one of the world’s leading touchscreen technologies. Like all capacitive-based touchscreen technologies, it uses an electrostatic field to detect touch commands. Surface capacitive touchscreens generate a uniform electrostatic field during use. They measure the capacitance of this electrostatic field to determine when and where touch commands occur. here are five things you need to know about surface capacitive touchscreens.
#1) Cost Less Than Projected Capacitive Touchscreens
You can expect to pay less for a surface capacitive touchscreen than a projected capacitive touchscreen. Surface capacitive and projected capacitive are both capacitive-based touchscreen technologies. Surface capacitive is a simpler technology, though. It involves the use of a conductive layer on one side of the insulator. With its simple design, surface capacitive touchscreens typically cost less than projected capacitive touchscreens.
#2) May Not Work With Gloves
If you’re looking for a touchscreen that will register touch commands performed with gloves, you may want to look elsewhere. While some touchscreens can, in fact, register touch commands performed with gloves, surface capacitive isn’t one of them. Surface capacitive touchscreens can register touch commands performed with a bare finger — as well as a conductive stylus — but they struggle to register touch commands performed with gloves, particularly thick gloves.
#3) Supports Multi-Touch Commands
Most surface capacitive touchscreens support multi-touch commands. Multi-touch commands are touch commands that involve multiple points of simultaneous contact. Touching the screen at two more places simultaneously is considered a multi-touch command. Surface capacitive touchscreens can typically register multi-touch commands such as this.
#4) Features a Glass Top Layer
The uppermost layer of surface capacitive touchscreens is made of glass. While there are exceptions, most surface capacitive touchscreen feature an all-glass top layer. Glass offers excellent light transmission. As a result, surface capacitive touchscreens produce clear, high-crystal images. Most of them feature an integrated liquid-crystal display (LCD). The LCD, along with its backlighting, will produce images that appear through the surface capacitive touchscreen’s all-glass top layer.
#5) Very Durable
You can rest assured knowing that surface capacitive touchscreens are very durable. The all-glass top layer is sealed. Even if it gets dirty, the dirt and contaminants won’t reach the underlying components, such as the controller and circuitry. Therefore, you can use surface capacitive touchscreens indoors or outdoors without fear of them succumbing to environmental damage. With their sealed design, they are very durable.
