The CIE positions D65 as the standard daylight illuminant: [D65] is intended to represent average daylight and has a correlated colour temperature of approximately 6500 K. CIE standard illuminant D65 should be used in all colorimetric calculations requiring representative daylight, unless there are specific reasons for using a different illuminant.
The projection system uses a simple 2.6 gamma curve, the nominal white luminance is 48 cd/m 2 (14ftL), and the white point is based on a projector with a xenon bulb, for a correlated color temperature (CCT) of ~6300 K. It is incorrect to refer to this as "D63" as this white point is not a CIE standard illuminant, and is not on the Planckian ...
In 2009, the National Institute of Standards and Technology (NIST) issued a scientific paper stating that in addition to the typical white light brightness rating of display devices, there was a need for providing "an equivalent measurement that will better describe a projector's color performance when rendering full color imagery".

Industrial laser projectors have been on the market since the early 2000s. Laser projectors are mainly used as optical guidance systems. They enable working without templates in many manufacturing processes by showing directly on the workpiece how material needs to be positioned or mounted, so that the employee is led by manual or semiautomatic productional processes visually.
Using a laser allows for generating almost monochromatic light. [45] [46] The NHK stated that at the time it was announced this 4K LCD has the widest color gamut of any display in the world. [47] On June 17, 2015, Digital Projection International presented a 4K LED projector with support for the Rec. 2020 color space. [48]
