That’s what some engineers are hoping for. Researchers from the Seoul National University have created a touchpad using hydrogel — the same substance used to make contact lenses. Hydrogen contains primarily lithium chloride salts, which are highly conductive while allowing for shape retention. The team behind the project believe these unique characteristics could pave the […]
While there are always exceptions, most smartphones produced and sold today use capacitive touch-sensing technology. We’ve talked about this before, but it’s worth mentioning again that capacitive is a type of touch-sensing technology in which a device identifies touch commands by measuring change in capacitance. You see, touching the surface of a capacitive device causes a […]
With the winter season fast approaching, many people will be pulling their gloves and mittens out of storage. But depending on the type of smartphone you own, wearing gloves may prevent you from using it. Certain touchscreen devices are not compatible with a gloved finger, forcing users to switch to a bare finger. So, why […]
In searching for new touchscreen solutions, you may come across the term “projected capacitance.” Based on the name alone, it’s difficult to comprehend what exactly this solution is or how it works. If you’re still scratching your head trying to grasp the concept of projected capacitance, keep reading to learn more about it. Projected capacitance […]
Touchscreen technology has become a mainstay in the modern-day world. It’s found everywhere from homes and workplaces to retail stores, restaurants, factories and even automobiles. Touchscreen devices live up to their namesake by allowing input via touch. The operator touches the display interface to perform various controls. But there are several different types of touchscreen […]
When researching the different technologies used in liquid crystal displays (LCD), you may come across something known as “in-plane switching,” or IPS. Based on the name alone, it’s difficult to decipher what exactly IPS is. So today we’re going to take a closer look at IPS, revealing how it works and why it’s becoming such […]
Dual touchscreen is a relatively new form of touchscreen technology that lives up to its namesake by featuring not one but two functional displays. Whether it’s a laptop, tablet, smartphone, desktop monitor, etc., most touchscreen devices have a single display. Dual-touchscreen devices, however, take the technology to another level by incorporating a second display. The most […]
Active-matrix organic light-emitting diode, or what’s more commonly referred to as AMOLED, is a special type of display technology that’s commonly used in smartphones, wearable electronics, laptops, televisions and other electronic displays. The “OLED” section refers to a thin film display that uses organic compounds from EL material, while the “AM” section refers to the […]
You’ve probably heard of touchscreen technology, but have you heard of touch switches? A touch switch is basically a type of electrical switch that’s operated through touch (hence the name). They are commonly used in lighting fixtures, computer terminals, and similar controllable devices. The operator doesn’t have to physically press down a button, but rather […]
From smartphones and tablets to computer monitors and automotive dashboard control panels, touchscreen technology is found just about everywhere you look. While the exact design and mechanics behind touchscreen devices varies, most of them are manufactured with a protective outer layer covering the display. Known as an oleophobic coating, it offers several key benefits worth […]
