Samsung's on a roll right now, with the Samsung Advanced Institute of technology having a pretty grand announcement today. They have successfully created "single crystalline Gallium Nitride on amorphous glass substrates", it may sound more Breaking Bad than TV or smartphone, but this achievement allows Samsung to make massive LEDs from normal glass, including, you guessed it, window panes.
Samsung says this scaled-up approach will allow them to not only drop production costs relative to most LED manufacturers, but also result in displays roughly 400 times larger! A Samsung spokseperson said to the Korea Herald "In ten years, window panes will double as lighting and display screens, giving personality to buildings". I'll take a few windows, hmm, and maybe a 300-inch 4096p, 240Hz window TV... thanks, Samsung.
