Touchscreens are the new age interface between human and computer interaction. No wonder it is one of the ultimate technologies of the digital age. But when we go deep inside the touch technology, the extraordinary experience is all down to the outstanding performance of the projected capacitive touchscreen. It is because we use a PCAP touchscreen in most computerized devices while working or spending leisure time.
So the first thought in mind comes as what makes a projected capacitive touchscreen versatile and popular in demand. With advancing consumer electronic devices, especially smartphones and tablets, capacitive touch technology has changed the way we interact with machines of all types in various environments. This technology allows us to scroll, zoom, pinch and lightly tap on our touch devices.
But again, what makes the devices sense the different kinds of gestures and how it reacts to them accurately? Projected capacitive touchscreen sensors typically consist of two parallel layers of conductive coatings, creating a vertical and horizontal patterned tracks behind a glass top layer. When a finger touches the glass screen, it creates capacitance between the horizontal and vertical patterned tracks. The controller scans each intersection of the horizontal and vertical tracks (which form a grid) with a high-frequency signal and identifies the touch point with the flow of radio frequency from one vertical trace onto a horizontal trace.
The touch and response is so accurate with a projected capacitive touchscreen panel that multiple industries prefer using this technology for their applications. Some other benefits of PCAP touch technology include:
Durability
The projected capacitive touchscreen is very strong and durable; thus, commercial applications make great use of it. Carefully selected and precisely designed projected capacitive touchscreens like the ones from A D Metro are resistant to typical issues like scratch, dirt and fingerprint smudges. Unlike other touch technologies, PCAP touch panels, with no moving parts, no front coatings, and mounted optics/transducers, last longer. It continues to function normally until the rear-mounted conductive matrix is damaged by breakage.
Highly Sensitive
While in resistive touchscreens, a higher amount of pressure is required to operate them. Whereas, the projected capacitive touchscreen is highly sensitive and can react to light touch events. The chances of false touch are unlikely as it responds to only a bare finger or conductive stylus.
Image Clarity
As projected capacitive touchscreens are usually constructed using clear, uncoated glass, with a matrix of invisible conductors on the rear face, they offer great optical clarity when compared to their counterparts. This makes capacitive screens a good choice for the latest high definition, UHD and OLED displays.
To make these benefits turn tangible, you need to have the right quality projected capacitive touchscreen. A D Metro offers an innovative range of PCAP touchscreens comprising a patented group controller where a common controller serves multiple screen sizes, helping to simplify design and reduce inventory costs. The controller offers USB-HID compatibility with major operating systems, offering the ultimate solution for challenging environments, especially outdoor applications like ATM’s, self-service POS, slot machines, interactive digital signage and touch tables.
