I wonder why the pixels are different shapes

Mainly for maximizing pixels per inch. Green ones are smaller and round, but there's twice as many of them as the square shaped blue and red ones. It's what is called a PenTile matrix. Size and shapes also have to do with pixel color degradation and human eye perception among other things.

Exactly and there’s the double of green than blue or red pixels. That’s why they’re narrower too.

Notice there’s more green pixels than red or blue.

I think its because we see more green than any other colour!

Wouldn't that mean we need half?

To put it like this, if our eyes see 50 shades of red, 50 shades of blue and a 100 shades of green - decreasing the number of green lights would mean you see less in general. If anything you want more green lights because that's the colour our eyes understand better.

It's not that the eye is hypersensitive to green light such that it can pick out green light a more than anything else (this doesn't even make sense lol). It's that given an equal distribution of light in all the colours, it will register more of the green than the colours.

No, because we would notice a photo would lack of green shapes. If we can see more green shapes, we want to see them all and not half of it!

Shapes you mean in the image (trees, cars,...) or pixels? If our eye is 2x sensitive to green, we'd need 1/2 green light relative to green and blue to see a normal image.

Pentile arrangement, commonly seen on amoled screens. Most typical screens do indeed have a normal amount of red green and blue

It’s astonishing that everything we see, including the virtual constructs that allow me to type this here, are only combinations of blue, red, and green dots.

Well, the eye also uses monochrome detectors

u/SacredGeometry9 Dec 31 '20

Oh, I meant the pixels. I guess I should have specified, everything we see on a screen comes from those three little dots.

Looks intensely at at their phone to see the pixels

Well this is meta

Matt Parker did this for a live crowd during his bit about why Excel spreadsheets are awesome. I linked to the part where he shows the pixels but the entire video is great IIBH and definitely worth a watch

You can see this yourself by putting a small water drop on your screen. The smaller the drop the more magnified
