- A stylus tip is a device used to draw or make selections by tapping on a screen.
- An S Pen for Samsung smartphones and tablets is a good example of a stylus tip.
- Stylus tips are used on resistive touchscreens, that use a bit of pressure on the screen to reflect touches, scrolls, and swipes.
- A resistive touchscreen is different from a capacitive touch display, which only relies on direct contact between the finger and the screen.
- Resistive touchscreens accommodate fingers and other stylus tips.
- Resistive touchscreens have several layers including a plastic and a glass layer.
- These glass and plastic layers are coated with a conductive material and lined up with electric charges.
- Electrical resistance is created between both layers which makes charges move sideways or top to bottom.
- When a finger or stylus tip presses down on the tablet screen, both electric films meet.
- The resistance between both layers at the point of contact gives an accurate measurement of the touch position.
- These processes give you the appropriate responses to the strokes of the S Pen on your tablet/phone screen.
