New Metrics to Measure Brightness

At the outset, we would like to inform readers that this is the second part (the first part can be found here ) of the translation of the article “Exploring OL Brightness – Improvements, WOL vs QD-OL and the Ne for New Metrics and Specs” originally publish on February 15, 2024, at TFTCentral portal . The author of the original is Simon Baker, who, together with TFTCentral, is the sole owner of the copyright. Thanks to their permission, we can now bring you the text in Czech and on Interval.

A new model is ne to express the true “brightness” of the display.

 approach and scale where:

The percentage difference between two data points will represent at least an approximate difference that we perceive visually. So if one reading was 30% higher than the other on this scale. Would mean roughly a 30% difference in actual perceiv brightness. This is probably a much more useful metric than trying to compare differences in raw brightness.
The scale should also take into account how we perceive different colors, take into account the chromatic component and adjust the output numbers accordingly. The scale would then also “balance” the different colors against each other and take into account how we perceive them visually, and not just be bas on a pure brightness number from the measuring device.
Color gamut and color vibrancy should also be taken into account. Even in the event that two brightness values japan phone number data ​​may be the same, consideration will be given to which of the colors will appear and appear brighter as a result of this vibrancy.
XCR (eXperienc Color Range

phone number data

One very good approach is the new

luminance model , which was develop in the Munsell Color Science Lab at RIT with financial support from Samsung Display (the panel maker, not Samsung Electronics display maker). The application of the HK model to the perception of brightness in displays the ease of creating reusable is referr to by Samsung Display as “eXperienc Color Range”, abbreviat as “XCR”.

XCR is bas on a mathematical model of human visual performance obtain from psychovisual cz lists experiments. This approach can fulfill the requirements that we mention above. Importantly, it also takes into account the effect of color along with brightness.
