How Do Touchscreens Work?
We use touchscreen displays for hours every day, but do you know about all the intricate layers and components that make them work? This episode goes into the structure and basic function of a touchscreen display. What goes into making toughened glass strong, how do capacitive touchscreens work, and how do OLEDs work? The merging of these technologies is what arguably makes the smartphone what it is! Take a look and learn more.

LG Prada Predated the Iphone. LG Prada was released announced December 12th 2006 and sales started in May 2007.
5:43 Most smartphones use a pentile subpixel layout which is 2x Green for 1x Red and 1x Blue.
7:25 1Pixel = 1G+1B or 1G + 1R. Thus the latest phones are closer to 6.67Million itty bitty lights.
