Screen Density and Its terminologies

Screen Density is a calculation of the proportion of display character positions on the screen or an area of the screen containing something.

There are Two types of Screen Density as following.

  1. Overall density of screen :
    The overall density of screen is measure by the percentage positions of a character on the overall screen.

  2. Local density of screen :
    Local density is a measure of how “tightly packed” the screen is at a specific region of the screen.

Example-1 :
Let’s consider the Text using Space i, e unordered.



Note –
In this case: overall density will be 13% (13 lines) so much space is used.

Example-2 :
Let consider the data in this screen.

Note –
In this case, overall density will be 5% (5 lines) so 8 lines space is reduced. So this screen is best.

Terminologies :
