Dots per inch

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.

DPI measurement in monitor resolution in pixels

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.

DPI

DPI may refer to:

  • Dots per inch, a measure of printing resolution
  • Dhaka Polytechnic Institute, an educational institution of Bangladesh
  • Deep packet inspection, a form of computer network packet filtering
  • New South Wales Department of Primary Industries (NSW DPI), an Australian governmental unit
  • Department of Public Information, related to U.N.
  • Digital Program Insertion
  • Disabled Peoples' International, an international non-governmental organization
  • Disposable personal income
  • Dry powder inhaler, a drug delivery device
  • Dual Polarisation Interferometry
  • Dye penetrant inspection, a nondestructive testing method
  • SystemVerilog DPI (Direct Programming Interface)

  • DPI-3290

    DPI-3290 was discovered by Delta Pharmaceutical and is a drug that is used in scientific research. It is a potent analgesic drug, which produces little respiratory depression.

    DPI-3290 acts as an agonist at both μ- and δ-opioid receptor, with an IC50 of 6.2nM at μ and 1.0nM at δ.

    Eden

    by: Die Happy

    There's war in the heavens
    Rebellion on high
    the son of the morning
    Descends from a black sky
    Severed and broken
    His wings burned to dust
    His coverings of diamonds and gold
    In a moment in time dissolve to rust
    Thunder and lightning
    Shatter the night
    The dragon of darkness
    Appears cursed by the keeper of the light
    The dark is chosen
    The scroll has been sealed
    Hidden in verses of prophets
    His face is revealed
    Songs of glory
    Shout across the land
    I can take you there
    Child of mine, take my hand
    Down through the ages
    The story's been told
    The daughter of wisdom
    Beguiled by the serpent of old
    Born into sin in a valley of thorns
    Torn from enchantment and
    Tossed into the eye of the storm
    Heaven's garden
    Made by God for man
    This is paradise
    Child of mine, take my hand
    Glory to glory
    Sin after sin
    The rider of death
    Pushes on to the place where
    The battle must begin
    Songs of glory
    Shout across the land
    This is paradise
    Won't you take my hand
    Heaven's garden
    Made by God for man
    This is paradise
    Child of mine, take my hand
    Oh, take my hand
