Someone asked me to talk about how computer monitors work on thursday morning. I know how Cathode Ray Tubes work and didnt have to research much to clue up on the differences between TVs and monitors. But I felt like addressing the subject of flat screens too, since I have the internet at my disposal. I found this page: http://computer.howstuffworks.com/lcd3.htm which I think is just great. Its the bit about Liquid Crystal Displays that I never understood: how do they interact with the polarity of light? And you can click on the switch in the diagram and see it working! Its great!
