How do touchscreens work? Every day we tap, swipe, pinch, and scroll on our smartphones, tablets, ATMs, laptops, and gaming consoles — but what’s really happening beneath the glass? In this episode of Miracles of Science, we uncover the fascinating history and technology that makes the touchscreen revolution possible.

From the first finger-driven touch panel in 1965 to the LG Prada and iPhone in 2007, touchscreens have evolved into one of the most indispensable inventions of modern life. We’ll break down how resistive touchscreens (used in ATMs, kiosks, and POS systems) differ from capacitive touchscreens (used in smartphones, tablets, and modern devices), and why features like multi-touch gestures — pinch, zoom, and swipe — only work on capacitive screens.

You’ll also learn:

Why toughened aluminosilicate glass is used in smartphones, and how potassium atoms make your screen five times stronger than regular glass.
Why gloves don’t work on touchscreens (unless they have conductive fingertips).
The role of Indium Tin Oxide (ITO) layers in conducting signals across your screen.
How projected capacitive technology enables precise touch control in modern devices.
Why capacitive screens are clearer than resistive screens, transmitting up to 90% of light.
Cutting-edge innovations like Surface Acoustic Wave (SAW) touchscreens that use sound waves instead of pressure or electricity.

Touchscreens aren’t just convenient; they’ve replaced hundreds of mechanical parts with invisible layers of glass and circuits, making devices more durable, versatile, and responsive. Whether you’re scrolling Instagram, typing on WhatsApp, or playing games, touchscreens adapt instantly to your needs.

If you’ve ever searched for how do touchscreens work, resistive vs capacitive touchscreen, touchscreen history, capacitive touch explained, touchscreen glass strength, why gloves don’t work on smartphones, touchscreen science, touchscreen durability, this video gives you the rational and scientific perspective.

Stay tuned till the end for the full story of how layers of glass, atoms, and electricity work together to power the everyday magic of your devices.
