What is a CRT?

Cathode-Ray Tube TVs were the norm for a very long time before the rise of LCDs. They work very differently from today's LCD and OLED screen technologies, instead of fixed pixels being lit up by a backlight (or lit themselves on OLED), it's electron guns firing photons on the phosphors that are inside the screen glass creating the image on the screen. Those TVs have the advantage of having no input-lag or ghosting, and handling low-resolution way better than modern screens because of them not having a fixed resolution and the "scan line" effect on some TVs. This is my attempt at recreating the TV I used to have as a kid.
