The pressure from your touch causes the two layers in the resistive system to touch, changing the electric field. A microchip inside the tablet interprets this change in the field and translates it into coordinates on the screen. The tablet’s CPU takes these coordinates and maps them against its operating system. The CPU determines that you have activated the app and launches it for you.
What are the components of an Android tablet?
These are the physical components that make up the Android tablet device — processors, sensors, wires and circuit boards. On top of this layer rests the kernel.

Pad U1 at the Consumer Electronics Show in Las Vegas, Nev. At first glance, it looked like a normal laptop computer.
You could be wondering “How do touch screens work on tablets?”
One source claimed that there are two basic methods of creating touch screens for tablet devices: resistive screens and capacitive screens. Manufacturers have to choose between the two — they don’t work together. Resistive systems detect a touch on a screen through pressure. Tablets that require a stylus often use resistive screens. But how does it work?
