What is a stylus and what is it used for?

The article describes what a stylus is, what it is for, what it is and whether it is used now.

The Digital Age

In our time, it has long been difficult to surprise someone with digital technology, computers, tablets and other things. Such things are developing very quickly when compared with other industries. And every year scientists and developers are finding new solutions and applications for such technologies. Now the simplest smartphone can successfully replace dozens of devices, and its possibilities are almost limitless, especially if we talk about phones with an open OS.

But even some 15 years ago, even ordinary computers were not at all, their performance left much to be desired, and many only dreamed of unlimited high-speed access to the network. It was then that the first smartphones and tablets with full-fledged operating systems began to appear, under which various applications could be created. Their main feature was multitasking and touch screens. And for a long time for such displays needed styluses. So what is a stylus, what are they and are they used in our time? In this we will understand.


what is the stylus

A stylus is a small plastic or iron stick with a special tip, silicone or capacitive. And you need a stylus to control touch screens. But how can they not control the fingers, as everyone is used to? Not always. Sometimes pressing fingers with small icons and symbols is not as convenient as a stylus. In addition, the accuracy of his clicks is always much higher, as well as the speed of work. So now we know what a stylus is. Now they are not so common, but before you could often see the happy owners of new-fangled smartphones with stylus. And by the way, they were often lost or broken, and then you had to use your fingers, matches, or toothpicks.

Now there are almost no devices that would be supplied with stylus, and the whole thing is not that the interface elements have become larger or people are used to clicking on the display with their fingers, but that the technologies of touch monitors have changed. With the fact that such a stylus, we figured out in general terms, now let's talk about new display technologies.


stylus for the screen

The very first touch screens were based on the resistive principle of operation. Simply put, their work was based on the banal closure. Microinsulators were applied between the monitor and the flexible outer plastic panel, and at the moment of contact a closure occurred at a given point, its signal was processed by a special device, which, depending on the point of depression, was converted into display coordinates. It is for them that a stylus is needed for the screen, because it reacts to hard pressing, and just touching a finger is not enough.

And yet you can use them without the stylus. When they are lost or broken, you can click on the screen, for example, with a fingernail or other hard object. The advantages of such touch screens include faster typing and the fact that over time, when the external plastic panel becomes scratched, it can be easily replaced. Such monitors are often used in factories and in those conditions when reliability is important, and the sensor can be activated by any object or simply by strong pressing, even when the fingers are dirty or protected by gloves.


capacitive stylus

The second type of touchscreen, which is ubiquitous now, is capacitive. They are arranged as follows: the display covers a thin conductive layer, and at the time of contact of the material, which also conducts current, the resistance in the display section changes, which serves as a signal of pressing or other action. Simply put, these touch-sensitive displays respond to the simple touch of a finger, and it does not have to be strong. Also for them you can find a special touch stylus.

The advantages of such displays include convenience and reliability, since foreign objects that do not conduct electricity, cannot accidentally turn on the device or perform another operation. And to the minuses - the fact that if the fingers in the glove are covered with liquid or dirt, the screen will not respond.

But now it is increasingly possible to find a capacitive stylus on sale, which can be controlled by a touch screen of this technology. Basically, it is needed for artists who want to draw on tablets with capacitive displays.


touch stylus

If we talk about how the styluses are arranged, then everything is simple. Those designed for resistive monitors are simply plastic or metal sticks with tips that do not scratch the top layer of the display.

The device is also capacitive stylus uncomplicated. Its tip is made of a material that conducts current in the same way as a human finger and changes resistance in a given area of ​​the monitor.

So we figured out what a stylus is and what it is for.
