resistive

Resistive refers to a technology that works by detecting physical pressure applied to the screen surface.

How it works:

1. Two flexible layers
   A resistive touchscreen is built with two thin, transparent layers:

   • The top layer (flexible, usually plastic)

   • The bottom layer (rigid, usually glass)
     Both layers are coated with a conductive material.

2. Thin gap with spacers
   The layers are separated by a small gap with insulating spacers, preventing them from touching normally.

3. Applying pressure
   When you press on the screen (with a finger, stylus, or almost any object), the top layer bends and makes contact with the bottom layer at the touch point.

4. Change in resistance
   The contact causes a change in electrical resistance at that exact location. The system measures this change to determine the coordinates of the touch.

Key points about resistive touchscreens:

• Works with anything: Fingers, gloves, styluses, pens, or other objects — no conductivity required.

• Pressure-based: Requires physical pressure, unlike capacitive which works by detecting electrical charge.

• Durability: Generally more resistant to dust and liquids, but the flexible top layer can wear out or scratch more easily.

• Single-touch only: Traditional resistive screens can only detect one touch point at a time (no multi-touch gestures like pinch-to-zoom).

Resistive touchscreens means the system registers input by measuring pressure that forces two conductive layers together, changing resistance at the point of contact.
