Display Bench: Generate photometric measurements under controlled lighting conditions

The Display Bench lets you measure color rendering and gamut, brightness, contrast, flicker, and angular photometry for displays in a variety of controlled lighting environments.

Mounted on a motorized translation stage, testing components include measurement instruments (colorimeter, spectrometer), and a 3-axis (X,Y,Z) holder for the DUT that can accommodate displays measuring up to 17 inches (diagonal) and  weighing 10 kg. You control mounted components using a supplied laptop equipped with the same software that DXOMARK uses in its Display protocol testing. The preinstalled software includes all test patterns and an open API for running customized measurements.

The Display Bench photometric measurements as described in the DXOMARK protocol are compliant with industry standards as defined by SID/ICDM and VESA. The bench has been developed in collaboration with industry-leading experts from Radiant Vision Systems and Konica Minolta.

The Display Bench, a light-tight 2m x 2m x 2m black box, keeps out all external light during testing. A supplied laptop is used to control the internal LED-based lighting environment, with brightness ranging from 0 lux to 20K lux from  a variety of illuminants (A, white LED, TL84, D65).

Video Analysis Kit: Analyze your device SDR & HDR video performance

Use SDR and HDR10 reference videos and documentation to perform video perceptual analysis. The Video Analysis Kit includes the reference content (videos produced by DXOMARK) and the documentation you need to perform perceptual analyses of HDR10 and SDR video quality, following DXOMARK’s Display protocol. Specific attention and contents will be related to brightness, contrast, detail, color, and quantization

Touch Bench: Measure your touch interface performance in real usages scenarios

DXOMARK’s CE-certified Touch Bench includes a Phantom VEO E 340L high-speed camera, a robot with two actuated fingers, and a laptop with preinstalled software that together let you measure touch interface response time. With the touch bench API, you can easily calibrate your devices and create your own tests using preprogrammed motions. The robot is programmed to execute a series of use cases, including gaming and gallery viewing, which entail numerous repetitive gestures such as scrolling, zooming, and tap-selecting content all across the screen. The high-speed camera captures all of these gestures at 1,200 fps, and then our software processes and measures the camera output.

Dome System: Measure display readability in controlled lighting conditions from 15,000 lux to 60,000 lux

In response to manufacturers’ new algorithms and other compensatory technologies to make screens more readable in bright conditions, DXOMARK has developed a new tool — the Dome Ambient Lighting System, a dome-shaped light box that mimics diffused bright daylight conditions, coupled with a Radiant imaging colorimeter to measure the device adaptation to ambient lighting.

Using the Dome System in your lab will ensure 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 that could affect measurements.

Along with the colorimeter and spectroradiometer for performing measurements (that can be 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 setup permits a thorough analysis of 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 lux to 60,000 lux. The Dome System can test a wide range of displays — smartphones, tablets, laptop, and monitors (up to 18 inches). For wider displays, local measurement can be done by unmounting the black chamber.

Perceptual booth

For reproducible perceptual assessments, it is crucial to clearly define the setup and environment to minimize bias. DXOMARK’s perceptual booth achieves this by utilizing neutral gray materials and LED-based tunable lighting, allowing for the accurate reproduction of various lighting conditions through a dedicated API. This system can control multiple booths simultaneously and adjust the color temperature (CCT) from 2,750K to 10,000K, with irradiance levels reaching up to 10,000 lux at the base of the booth. This setup is an indispensable tool for ensuring reliable and consistent perceptual assessments.
