Type of cell phone screens
There is many types of screens , but im just going to talk about the most commonly used in smartphones.
they are:
_WVGA (480x800), HVGA(480x320).....this kind of screens isnt bad ,unless youre a hd game lover and you want a really great performance.
_AMOLED (active matrix organic light emitting diode) its used in smartphones, and "OLED" is just a thin layer of the screen ." Active matrix" refers to the layer that is behind the pixels.And this type of screens delivers better image quality than vga screens.
_SUPER AMOLED is a version of AMOLED display technology that consist of putting the capacitive touchscreen layer directly into the display instead of overlaying it on top of the display . This results in a thinner design that uses less power and reflects less light, and as a result it gives you a better screen visibility when you are outdoor
_LCD (liquid crystal display) the liquid crystals are not solid nor liquid, they are in a fourth state of matter (not gas, not liquid, not solid).And they dont deliver a great resolution and image quality.

Every pixel receives a frequency that determines the color of the light that it should produce.
