DXOMARK Dome System

Measure display readability (brightness and contrast), responsiveness, and color rendering in controlled lighting conditions from 15K to 60K lux.




Introduced in 2020, the DXOMARK Display protocol has provided scientifically rigorous and unbiased test results to consumers and OEMs about display performance.  

Up until very recently, displays have been hard to read in very bright conditions, such as the in the glare of diffuse full daylight or under direct sunlight. In response to manufacturers’ development of new algorithms and other compensatory technologies to make screens more readable in bright conditions, DXOMARK now incorporates a new tool in its Display protocol to measure these efforts — DOME Ambient Lighting System, a dome-shaped light box that mimics diffuse bright daylight conditions, coupled with a Radiant imaging colorimeter to measure the device adaptation to ambient lighting.

Using the Dome System in the lab ensures that all devices are tested under exactly the same conditions, unaffected by atmospheric conditions outdoors, such as high thin clouds, for example, that might cause subtle variations in light levels and thus affect measurements.  

Along with the colorimeter and spectroradiometer for performing measurements (purchased separately), the new bench setup includes the LED-based dome lighting system; an integrated luxmeter; computer-controlled motors for positioning the measuring instruments as well as the device under test; specially designed pattern targets, and software.   

This new addition to the Display protocol can thoroughly analyze display performance in the areas of readability (brightness and contrast), responsiveness to changes in light levels, and color rendering, under lighting conditions ranging from 15,000 to 60,000 lux. Dome System can test a wide range of displays — smartphones, tablets, laptop and monitors (up to 18 inches).
