Thus, the touchscreen is an integral part of any tablet, which you cannot do without.
Types of touchscreens
There are several types of screens that differ from each other in technical characteristics.
Resistive touchscreen
Is the cheapest, but nonetheless Excellent resistance to dirt and temperature changes.
One of the disadvantages will be extreme vulnerability to any mechanical damage. That is why such a screen often fails very quickly.
Capacitive touchscreen
Although it is more reliable than resistive, it is still unable to cope with exposure to water, bad weather and heavy pollution.
One of its features is using special touch glass.
Reference! In addition to those mentioned above, there are other types of screens: infrared, projected capacitive, induction and others. But the first two models are the most common.
How the touchscreen works
How the touch screen works depends on its specific variety. But for most of them it is approximately the same, not counting the features inherent in each species.
Many modern gadgets have a capacitive screen. It consists of a glass panel with a special resistive material applied on top.
Due to the fact that the human body is capable of conducting current, When you touch the screen, a special leak occurs, the location of which is determined by the controller. It receives this data from electrodes, they are located at the corners of the touch panel.
The main difference between a capacitive screen and a resistive screen is precisely that for the first one to work, this current is needed, which is transmitted by a person and human heat. A resistive touchscreen can respond to the touch of any object. These were installed in some older models of tablets and phones. They often came with a stylus. That is, a special element with which you could click on the screen.
Checking the touchscreen
Since this is one of the most essential elements of the tablet, The functionality of the touchscreen should be checked regularly.
Inspect it for any mechanical damage, for example, cracks. Then pay attention to correct perception of commands And The screen responds to any press.
If something is wrong, there may be several reasons for this: a sudden change in temperature, dirty display, dirt, and much more. In this case, it is better not to engage in amateur activities and immediately take the device for 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 possible problems associated with this control.
