@atpfm @siracusa During the OLED segment, you mentioned "tricks we play with LCDs to make the pixels change color really fast". Could you briefly explain what that means?

Is this about the physical construction of the screen? Or its controller? Or even the input video data? All of the above?

(I'm more than happy to do my own research, but maybe you at least have a useful link or a keyword for me to google? Thanks in advance!)

@isametry “Overshoot” is a good keyword, but it’s a bit of an over-simplification. LCDs often have lookup tables of how to get a pixel from one color to another color as quickly as possible, often passing through other very different colors on the way.

@siracusa Fascinating! The video did a great job of summarizing it I think. Thanks a lot!
