AS ISO 12646:2013 pdf download.Graphic technology- -Displays for colour proofing- Characteristics and viewing conditions.
AS ISO 12646 specifies the minimum requirements for the characteristics of displays to be used for soft proofing of colour images. Included are requirements for uniformity, convergence, refresh rate, display diagonal size, spatial resolution and glare of the screen surface. The dependence of colorimetric properties on the electrical drive signals and viewing direction, especially for flat panel displays, is also specified.

3 Terms, definitions and abbreviated terms
3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1.1
calibration
operation of establishing that the measured values agree with the values specified by a standard or a characterization process
3.1.2
characterization
process of relating device-dependent colour values to device-independent colour values
3.1.3
convergence
ability of the three electron beams (R, G and B) to come together at a single spot on the surface of the CRT (see 3.2)
NOTE Not applicable to FPDs (see 3.2).
3.1.4
DVD
design viewing direction
direction for which specific electro-optical characteristics of the display have been optimized
NOTE Examples of important electro-optical characteristics are maximum luminance and maximum contrast.
3.1.5
gamma
best-fit parameter which relates the monitor normalized output luminance to a normalized input digital value presented to the monitor system including its hardware and software components as given in Equation (1):
3.1.6
hard copy proofing system
system for simulating a printed image using a printing device which may be different from that used for production
3.1.7
OFF-state
condition in which the display is switched off
3.1.8
ON -state
condition in which the display is switched on
NOTE This definition is important for light-valve-like displays, which might emit a significant light intensity even when displaying the darkest image (R = G = B = 0) in the ON-state.
3.1.9
opto-electronic transfer function
relationship between the input values provided to, and the luminance values produced by, a display device
3.1.10
refresh rate
frequency with which the image on the screen is redrawn
NOTE The refresh rate is expressed in Hertz (Hz).AS ISO 12646 pdf download.
