How Do capacitive Touch Screens Work?
In the world of mobile phones, touch screen technology has revolutionized the way people can use their phones. Not only it is convenient but also provides users with better accuracy and quicker response time. Touch screen technology can be found in all sorts of mobile phones, smart phones, tablet PCs, laptops and various other items. In fact, it’s already present in your average digital camera and many other items, which people commonly use each day. It’s also prevalent in other electronics like touch screen computer, printers, TVs, car navigation systems, etc.
Simply put, a Touch Screen is basically an electronic unit that has been made with a touch screen material. Traditionally, when taking computers, the main input devices come with a mouse and keyboard. But in a touch screen phone, you actually can give the electronic system the user’s input, well, just by touching the screen itself. The result of this is a much clearer user interface, with a greater level of interaction than ever before.
Touch screen displays are made from a wide array of technologies like resistive, capacitive, or infrared. Capacitive touch screens provide a nice responsive experience because they are sensitive to touch. And since they use very little energy, they are the most energy efficient among the bunch.
Resistive touchscreen displays on the other hand, allow only very light to be passed through. So there’s no finger printing. They’re not too sensitive, either, so they’re not too annoying for the users. But they tend to have a shorter response time, less clarity, and are generally regarded as poor performers, too. With the exception of touch screens made with AMOLED technology, which has very clear and uniform colors, resistive screens are all gray, white, or black.
5-wire resistive touch screen technology is the most popular among today’s cellular phones and mobile devices. It offers a clearer, more responsive touch screen, which also has a greater resistance to scratching and other marks. This means text messages, emails, web surfing, and whatnot can be sent clearly and quickly, without having to speed up the message to try to touch the screen, which is a drag. And with today’s larger and thicker touch screens, text messages and email can be stored more easily on these types of screens.
While this touch screen technology is great in all regards, there are some drawbacks. The biggest drawback, and the one you should always be looking out for, are finger printing. Although it’s usually not visible at first, your fingerprints usually end up showing up. This can be very bothersome if you are trying to send private information over the internet, which is the primary use for touch screen technologies. In addition, text messaging can be awkward if you do not have steady hands. In order to type accurately and efficiently, you need to make sure you’ve got a good steady hand.
The next step up from the capacitive touch screen technologies are the resistive and capacitive types. Both of these types are capable of providing extremely sharp images. However, the resistive touch screen technologies allow for more intensive pressure and movements, such as pinch zooming. Furthermore, they generally offer clearer images, although not as crisp as those provided by capacitive technologies. Capacitive technologies are probably the best choice for laptops and tablet computers. The reason why is because the accuracy provided by capacitive touch screen technology is simply phenomenal!
capacitive touch screen technology uses circuitry to track the light that passes across the display unit. When the light touches the surface of the display unit, the circuitry will register that as a touch. If you hold a camera close to the touch screen of one of these input devices, then it will register your finger. These input devices are the best suited for use with electronic equipment such as video game consoles.
