High brightness sunlight readable monitors are typically used commercially in kiosks, vending systems, pipeline inspection systems, outdoor digital signage and advertising, in sports stadiums, in military vehicles, on ships for navigation systems, on bus and train platforms, and much more.
The nit (symbol: nt) is a non-SI name also used for this unit (1 nt = 1 cd/m 2). [1] The term nit is believed to come from the Latin word nitēre, "to shine". [2] As a measure of light emitted per unit area, this unit is frequently used to specify the brightness of a display device. The sRGB spec for monitors targets 80 cd/m 2. [3]
Brightness is the term for the subjective impression of the objective luminance measurement standard (see Objectivity (science) § Objectivity in measurement for the importance of this contrast). The SI unit for luminance is candela per square metre (cd/m 2). A non-SI term for the same unit is the nit.

The U.S. headquarters was opened with a staff of three in 1985, as Multitech Electronics USA, in Mountain View, California ...
Photometry is a branch of optics that deals with measuring light in terms of its perceived brightness to the human eye. [1] It is concerned with quantifying the amount of light that is emitted, transmitted, or received by an object or a system.
A truly dark sky has a surface brightness of 2 × 10 −4 cd m −2 or 21.8 mag arcsec −2. [9] [clarification needed] The peak surface brightness of the central region of the Orion Nebula is about 17 Mag/arcsec 2 (about 14 milli nits) and the outer bluish glow has a peak surface brightness of 21.3 Mag/arcsec 2 (about 0.27 millinits).

Brightness and contrast ratio: Contrast ratio is the ratio of the brightness of a full-on pixel to a full-off pixel. The LCD itself is only a light valve and does not generate light; the light comes from a backlight that is either fluorescent or a set of LEDs .
Video black level is defined as the level of brightness at the darkest (black) part of a visual image or the level of brightness at which no light is emitted from a screen, resulting in a pure black screen. Video displays generally need to be calibrated so that the displayed black is true to the black information in the video signal. If the ...
