What is BS IEC 62977‑2‑2 about?
BS IEC 62977‑2‑2 is an international standard used for electronic displays that specifies the measurement methods which helps in determining the optical characteristics and result in producing better quality electronic display devices.
BS IEC 62977‑2‑2 is the second part of electronic displays in multi-series.
BS IEC 62977‑2‑2 specifies standard measurement conditions and measuring methods for determining the optical characteristics of electronic displays under indoor and outdoor illumination conditions. Standard illumination geometries are specified and the reflection properties of flat screens are determined under those conditions. Reference illumination levels and spectra are used to estimate the photometric and colourimetric characteristics of electronic displays under the same conditions. These methods apply to emissive, transmissive, and reflective displays, or combinations thereof, that render real 2D images on a flat-screen.
Who is BS IEC 62977‑2‑2 for?
BS IEC 62977‑2‑2 on electronic displays is useful for:
- Manufacturers of electronic displays devices
- Electrical engineers
- Theatres
Why should you use BS IEC 62977‑2‑2?
Optical measurement is a method of monitoring critical dimensions of manufactured parts in many industries. This optical measurement refers to noncontact measurement using various light sources.
BS IEC 62977-2-2 helps in measuring the spectral reflectance and reflection coefficients of the display surface, specific to the geometry of the light source. This illuminance is used in representing the use of a display that is viewed indoors or in direct daylight. The calibrated reflection is useful in determining the reflection properties of displays.
The darkroom luminance and spectra method mentioned in BS IEC 62977-2-2 is helpful in measuring emitted spectra and luminance from a display placed in a dark room. Reflection measurements help in measuring the reflection properties of a display under defined illumination conditions. BS IEC 62977-2-2 guidelines can be used to determine the optical characteristics of a display under indoor and outdoor illumination conditions. Standard measuring conditions helps in measuring the environmental conditions which result in sustaining the display devices in different climatic conditions.
BS IEC 62977-2-2 specifies the measurement method and conditions that help in determining the optical characteristics of electronic displays devices under illumination conditions which result in producing better quality electronic display devices.
