What exactly are pixels i mean aren’t they just your screen how do they get burnt in? And why are some screens seemingly immune?

For many screen types, keeping a static image on the screen for extended periods of time can cause the individual pixel chemistry in the screen to degrade faster, causing discolouration.
It’s like if you had a big wall of incandescent bulbs and you turn each one on based on the brightness in that spot of the image, if you leave that image up for too long, some bulbs might burn out or blacken quicker in the bright patches, and the damage in that pattern would remain even after you change the image.

A pixel is a small dot of light and color on your screen that makes up the images you see.
Pixels can be different colors depending on how much red, green, and blue light they emit.
Some screens use plasma, which is a gas that glows when electricity passes through it.
Plasma screens have tiny cells of gas that act like pixels.
Each cell has phosphor material that emits light when hit by photons.
The problem with plasma screens is that if you leave a still image on for too long, the phosphor material can lose its brightness and only show the same color over and over.
This is called burn-in, because it looks like the image is burned into the screen.
Other screens use LCD or LED, which are liquid crystals that filter white light from a backlight.
LCD and LED screens have tiny filters that block or allow light to pass through and create colors for each pixel.
The problem with LCD and LED screens is that if you leave a still image on for too long, the liquid crystals can get stuck in one position and not return to their normal state.
This is called image persistence, because it looks like the image persists on the screen even when it changes.
Each pixel is a separate thing that wears out individually. Literally a completely separate tiny whatever. Your screen doesn’t just have a million pixels as a mathematical number, it really does have a million precisely manufactured microscopic parts. Luckily they don’t have to manufacture them all individually and glue them together.
You don’t notice if your whole screen wore out a bit. But you do notice when some spots wear out more than other spots because that makes a picture.
Some types of screens are immune just because the pixels don’t wear out that way. Some other screens have processing that compensates for it by making the worn out pixels brighter (it keeps track of how much each pixel was used).
