How do touchscreens work? Types of touchscreens
When you touch the screen, you interrupt the sound beams and absorb some of their energy The screen's microchip controller figures out from this where Resistive touch screens work exactly how their name implies with resistance to touch A glass or hard plastic layer is blanketed by a resistive metallic layer that conducts charge The two are separated by spacers in the screen so that when your finger presses firmly on the plastic protective layer, the two layers make contact changing the electric charge at that location, which cues the software to respondHow Do Touch Screens Work on Laptops and Tablets?When you touch the screen with your finger, your body temporarily absorbs some of the electricity, similar to how your body transfers electricity when touching a metal surface A touch screen uses so little electricity, however, that you won't feel a shock This How Does a Touch Screen Work?
