What is a touchscreen on a tablet: the meaning of the name, types and effects of touchscreens

Most modern gadgets are equipped with a touch screen. It has already become familiar to users as an element of a variety of devices. Today, smartphones and laptops are equipped with a similar feature. This element is especially important in the configuration of tablets.

But not everyone knows the name “touchscreen”. What is it and what features does it have? What are its varieties, as well as the principle of action? You will learn about all this in this article, which will definitely be useful to any tablet owner.

What is a touchscreen

Despite the fact that the name may seem complicated, those who speak English could already guess what it is. This name is derived from English words:

• touchthat translates to "touch»;
• screen — «screen».

Simply put, this is the same touch screen, which many are accustomed to using when controlling a smartphone, tablet or some other modern gadget.

This is one of the most convenient ways to operate the device. Because users no longer have to use any external keyboard or other controls. It is also not necessary to memorize the functionality of each button.

IMPORTANT! To select the desired icon on the screen, just click on it. The built-in touch keyboard allows you to type any text and use emoticons or stickers.

Thus, the touchscreen is an integral part of any tablet, without which it is impossible to do.

Varieties of touchscreens

There are several types of screens that differ from each other in technical specifications.

Resistive touchscreen

Is the cheapest, but nonetheless excellent resistance to pollution and temperature extremes.

One of the minuses will be extreme vulnerability to any mechanical damage. That is why such a screen often very quickly fails.

Capacitive touchscreen

Although more reliable than resistive, still unable to cope with exposure to water, bad weather and heavy pollution.

One of its features is using a special touch glass.

Reference! In addition to the above, there are other types of screens: infrared, projection-capacitive, induction and others. But the first two models are most common.

The principle of operation of the touchscreen

The principle of operation of the touch screen depends on its specific variety. But for most of them it is approximately the same, apart from the features inherent in each species.

Many modern gadgets have a capacitive screen. It consists of a glass panel with a special resistive material deposited on top.

Due to the fact that the human body is able to conduct current, when you touch the screen, a special leak occurs, the place of which is determined by the controller. He receives this data from the electrodes, they are located at the corners of the touch panel.

The main difference between a capacitive screen and a resistive one is that the first one needs this current, which transmits a person and human heat. Resistive touchscreen can respond to the touch of any object. Such were installed in some older models of tablets and phones. A stylus was often included with them. That is, a special element with which you can click on the screen.

Touchscreen Check

Since this is one of the most essential elements of a tablet, the performance of the touchscreen should be checked regularly.

Inspect it for any mechanical damagefor example cracks. Then pay attention to correct perception of commands and triggering the screen for any clicks.

If something is wrong, there may be several reasons for this: a sharp change in temperature, a dirty display, dirt and much more. In this case, it is better not to engage in amateur activity and immediately take the device to repair, where professionals will replace the touchscreen.

Now you know what a touchscreen on a tablet is, what they are and how they differ, as well as about possible problems associated with this control.
