For clarity, I wasn’t paid to make this video. I’ve been piecing it together for the last couple of years when I had time. I did, however receive a free LG TV to feature OLED technology in this video.

    Stupid question: on the CRT, why can we see a few lines above the “currently displayed” line? Is it just the pixels decaying?

    • David Creigh says:

      From what I understand, the Phosphor on the screen glows in response to the concentrated electrons, and it takes a little bit of time for that glow to dissipate.

    Scanning top to bottom is preferred because you move your eyes left and right more than up and down. If you move your eyes quickly up and down looking at a CRT TV you will see a disturbance as you eyes move with or against the scanning, this would be irritating if it happened with left-right eye movement. The left to right scanning is 600 times faster, so it’s not noticable.

    So even right now we are watching hundreds of images being projected fast on our screens.

    Did anyone else hear the TVs high frequency sound? (Think that’s what it’s called)

    It’s crazy how a CRT TV is regarded as a shitty tv nowadays but it’s an amazingly engineered piece of technology.

      American made products that actually work

    • Andy says:

      Crt= damages more your eyes because of the flickering, low resolution.
      LCD: no flickering, although the blue light from the leds damages your eyes. 4 to 8k res
      Oled: same shit tbh.

    • xdragon2k says:

      It’s shitty because it gives out too much radiation and it’s really bulky compared to the newer tech. TV in general are amazing piece of technology.

    • doggod101 says:

      It’s pretty incredible how complex they are compared to something like OLED which is literally just miniaturized lights on a switch, we seem to work backwards when it comes to display technology.

    • psynrg says:

      A sheet of paper is an amazingly engineered piece of tech. Don’t let nostalgia cloud your vision of just how far forward a UHD+ OLED TV is vs. CRT.
