Every TV Screen TYPE Explained in 11 Minutes!

From bulky glass monsters to razor-thin panels that look like windows of light, this video breaks down the real science behind how TVs evolved. We start with CRTs—high-voltage electron guns firing beams at glowing phosphors—then move through projection TVs that relied on mirrors and optics instead of pixels. You’ll learn why plasma screens ran hot like space heaters, how LCDs work by twisting liquid crystals to block light, and why “LED TVs” were really a smarter version of LCD all along. We also dive into the rise and fall of 3D TV, explain the true difference between OLED and QLED without marketing fluff, and finish with laser TVs that use microscopic mirrors and ultra-short-throw lenses to paint massive images on your wall.

This is not a spec sheet rundown—it’s a plain-spoken, physics-level look at why each technology existed, what it did better than the last, and why some old displays still feel more “alive” than modern screens.
