Why does an image formed by pixels on a screen remain sharp, when light tends to spread out over distance?
The image from the screen *does* become wider as you get away from it, the same way it does from a torch (or, for our American friends, a flashlight – I had a very amusing conversation with an American when I referred to it as a torch and she didn't know what I was talking about!) That's why if y…
The Short Answer

That's why if you and I sit a few metres apart, we can both see the same screen. However, unlike the torch, each pixel is generating light in a very tiny place. From that place, light is emitted in all directions – but only one of those directions lines up with your eye, which is why it remains sharp when it reaches your eye.
