Well it all depends on the display resolution. A screen resolution is the number of pixels on a display screen. That's why you can see these specifications when you check on a smartphone before buying one.
The higher the resolution the higher the pixels. Pixels are the basic unit of programmable color on a computer display or in a computer image. Basically its a dot with color
.
Basic color for imagery is Red, Blue, Green or "RGB" these three colors are combined digitally to produce the image being transmitted to our screens.
Let me put it this way..
Imagine a piece of white paper with 3 M&M's on it. 1 Red , 1 Green Blue. Put it all together in circular pattern and slowly close your eyes focusing on it. At one point you will see a blurred image but its kind of a combination of colors. That is how display screen works. When they control a color on a pixel using digital signal its actually combining the three colors. Now imagine that piece of paper with all the RGB M&M's , that's how resolution works. The more pixels the clearer and more detailed image.....
I hope this help..
Now lets eat those M&M's....
