Software as a service (SaaS) has become the most extensively used software distribution model across the globe because of its apparent benefits over traditional on-premise systems. An increasing number of businesses in all major industries are opting for SaaS solutions to strengthen their IT infrastructure. Seeing the current trends, the journal PR Newswire predicts that the global SaaS market is expected to grow to $307.3 billion by 2026. It represents a massive growth as compared to the…
ContinueThe moment your finger or specialized input device, including atoms with positive or negative charges, will come in contact with the display, it will detect a disturbance in the electrical field and execute the command. Touch screens that use capacitive technology are relatively sensitive and provide a higher level of contrast and clarity.
The capacitive touch screens have a copper coating or indium tin oxide for storing electrical charges, while the electrostatic grid of wires is much thinner than human hair. The capacitive displays obey the laws of physics because they are controlled by the changing electric fields and their effects on capacitance.
As a consequence, one can logically conclude that there is more to learn about capacitive touch panels.
This section discusses the qualities of capacitive touch panels that make them so prevalent.
Anti-Glare (AG): In bright light environments or the outdoors, anti-glare touchscreens create micro-asperities on their surfaces, improving the screen's visibility. There exist two methods of manufacturing: controlled acid etching and chemical-based surface treatment.
Anti-Reflective (AR): By applying a coating to the surface of the screen, an anti-reflective screen minimizes reflections. Due to low reflection, this method can also improve the efficiency of imaging systems in general.
Anti-Fingerprint (AF): With an anti-fingerprint coating, scratches are limited to the screen, and smudging and fingerprints are prevented. It is easier to wipe away smudges on the touch panel with the AF surface, making it even more aesthetically pleasing and easier to clean. AFP coatings reduce friction, which enhances scratch resistance. They are hydrophobic.
Wet Functionality: Thanks to its wet-touch functionality, the capacitive touch panel can function even when it is wet. When wet hands touch the screen, the touchscreen may not respond because of the distortion of the electrostatic field. Additionally, the capacitive touch panel includes a sensor that will let you know whether your screen is dry or wet. The dry-touch or damp touch will simultaneously switch between single and multi-finger touch and minimize false signals.
Glove application: Some capacitive touch panels work with coated gloves even though they are not compatible with the gloves. Gloves coated with silicone can affect touchscreen functionality and responsiveness based on fingertip pressure or time.
Wrapping It Up!
By the end of this article, you can easily understand that capacitive touch panel technology is not as straightforward as it might look. It simply depends on many factors such as the coating thickness and finger pressure how effective capacitive touchscreens are. Testing is, therefore, the only way to determine the effectiveness.
One of the world's leading manufacturers of LCDs and touch panels, Microtips Technology, has developed capacitive touch panels that feature special coatings. Their products are designed for extensive use cases in a wide range of industries, including healthcare, education, corporations, banking, and research.
