Dots per inch (DPI, or dpi) is a measure of spatial printing or video dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch (2.54 cm).
Monitors do not have dots, but do have pixels; the closely related concept for monitors and images is pixels per inch or PPI. Many resources, including the Android developer guide, will use the term DPI interchangeably with PPI, however.
Old CRT type video displays were almost universally rated in dot pitch, which refers to the spacing between the sub-pixel red, green and blue dots which made up the pixels themselves. Monitor manufacturers used the term "dot trio pitch", the measurement of the distance between the centers of adjacent groups of three dots/rectangles/squares on the CRT screen. Monitors commonly used dot pitches of 0.39, 0.33, 0.32, 0.29, 0.27, 0.25, or 0.22 millimetres [mm] (0.0087 in).
LCD monitors have a trio of sub pixels, which are more easily measured.
Tomorrow I will go to San Francisco
I bought the flight by accident last night
Later I´ll be dancing down in Rio
And Australia is on the other side
[Bridge]
I´m sick of this security I have with every step I ever
make
It´s like hell
Even if your words would fly like butterflies
I would not be afraid
´cause there´s nothing left to say
[Chorus]
Your commentary is not necessary
I made up my mind today
And noone can say
That it´s too far away
Coz I made up my mind today
and I´m sure
Many years have passed, they stole my longing
A trip around the world has been my dream
Behind the wall of silent hope, still waiting
That a princess in a golden cage is freed
[Bridge, Chorus]
I will taste the air on every continent
and maybe find a place to stay
I´ll think about your words when I see butterflies
and drink the best champagne
to your health
[1.strophe, Chorus(2x)]
