Look, we know you know all about LED backlights, light diffusion, subpixels, and the things that turn them on, but not everybody does. The humble LCD you're most likely reading this on still retains a level of mystery about the nitty gritty details of how it works for the vast majority of its users, so here's a terrific video breakdown of both its component parts and method of operation. Bill Hammack, a self-appointed Engineer Guy, takes us from the LED arrays that provide the light for most current LCDs, through all the filters and diffusers designed to make that light uniform, and into the ways thin film transistors make it possible for us to show moving color images of cats diving into boxes on such displays. It's exciting, deeply nerdy stuff, and it awaits your audience after the break.
