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