SPOTLIGHT: Sparkle Measurement

Evaluate the effect of “sparkle” in anti-glare display layers. The Radiant Sparkle Measurement Method quantifies sparkle using a mean pixel-level luminance variation percentage across the display. This value matches human determinations of acceptable display quality, which can be used to set measurable tolerances for films and coatings.

Pinpoint errors at the component level: cell/open cell, backlight unit (BLU), LCD module, cover glass, and films or coatings.

Things to consider:

• Do you know the source of your defect? When a display

reaches final assembly, several materials and processes

have already been applied—some defective or damaging.

Inspection at each layer stops issues at the source.

Example of anti-glare sparkle on LCD displays:

Luminance variation: 2.4% Human Rating: Acceptable

Luminance variation: 4.1% Human Rating: Poor

Radiant cameras measure and calculate correction factors for discrepancies in light output between subpixels in OLED, microLED, and other emissive display technologies.

SPOTLIGHT: Demura

The Radiant “demura” process corrects pixel uniformity in emissive displays. A high-resolution ProMetric system takes a measurement of each display subpixel and calculates the correction factors needed to equalize luminance output. These factors are then applied to each subpixel to adjust output and produce a display with a uniform appearance.

Radiant images of an OLED display before and after demura.

Things to consider:

• Demura correction reduces

waste of “defective” materials.

• Pixel shape, size, color, and

pattern vary from display to

display. Radiant software

dynamically registers all

pixels regardless of variation.

Things to consider:

• Displays in fixed integrations may be viewed off-angle.

Radiant’s FPD Conoscope Lens evaluates the visibility of a

display at view angles to ±70° in every direction at once.

• Achieve more versatility in a single instrument. Switch

between the FPD conoscope and standard lenses to use

Radiant cameras for other display measurements like

uniformity, pixel defects, mura, and more.

IRTUAL & AUGMENTED REALITY

Things to consider:

• Wide fields of view

create immersive

experiences.

Radiant’s AR/VR

lens captures 120°

horizontal FOV,

even at close range.

• Viewed at close proximity, display defects become more

apparent, so testing at the human eye position is crucial.

• With aperture located at the front, Radiant’s AR/VR lens

captures the complete display FOV as seen by the user.

URFACE INSPECTION

Engineered for light measurement, Radiant cameras offer superior imaging to capture subtle defects in high-value assemblies and surfaces.

SPOTLIGHT: “Just Noticeable Differences”

Things to consider:

• Quality doesn’t stop at the display. Radiant’s advanced

vision systems leverage light measurement advantages

to enable surface and assembly inspection beyond the

capabilities of humans and standard machine vision.

JND is the amount of change over an area that is noticeable to a human observer. Radiant software uses a JND value to detect and grade non-uniform areas of light and color in illuminated displays.This process can be extended to inspection of external devicesurfaces and coverglass to identify,classify, and gradethe severity of unknown defects in unknown locations.

Radiant high-resolution imagers capture each display pixel over an area of several sensor pixels.

Apply Radiant cameras at all stages of production to catch defects before final assembly.

EAD-UP DISPLAYS

SAE J1757-2 “Optical System HUD for Automotive” provides examples using Radiant cameras for standard measurement.

Radiant’s fully-automated HUD measurement solution syncs HUD test images with analyses.

Things to consider:

• SAE-standard HUD evaluation requires photometric

(brightness) and dimensional (location, position, distance)

measurements. Radiant imaging colorimeters provide a

single system to evaluate all aspects of the HUD projection.

• SAE-standard testing can be applied in R&D, quality

testing, and production to evaluate:

• Luminance

• Color

• Uniformity

• Contrast

• Pixel Defects

• MTF (Sharpness)

• Eyebox Limit

• Distortion

• Warping

• Ghosting

ABSOLUTE LUMINANCE & COLORRadiant ProMetric imaging systems incorporate specially-

engineered optical filters to replicate the human photopic

response to light and color, simulating visual perception.

CIE-matched cameras simulate the human eye’s response to various wavelengths of light.

The CIE color-matching functions provide the basis for obtaining quantifiable values of perceived color for scientific color measurement. Radiant imaging colorimeters replicate light intensity per wavelength given by these curves using a tristimulus filter system, adjusting exposure for each filter to ensure absolute measurement to human vision.

one- and four-color calibration (single-color or RGB

emitters); LED and white phosphor LED calibration

• Lensing effects: Distortion calibration (if applicable)

Before distortion calibration After distortion calibration

Things to consider:

• Measurement conditions change. Calibration ensures accurate,

absolute data across users, devices, and environments.

• Radiant cameras automatically apply calibrations for new focal

and aperture settings, removing this burden from the operator.

SPOTLIGHT: Black Mura Testing

In automotive Black Mura testing, lenses can be electronically defocused to meet the required modulation depth percentage (between 50-90%) to remove moiré interference. Refocusing the lens enables the same camera to inspect for small defects like stuck pixels, lines, particles, or surface scratches.

Defocus for moiré removal Refocus quickly for detail inspection

Things to consider:

• Electronically-controlled lenses remove human error by

adjusting to data points entered into the software.

• Locating objects or virtual images at multiple depths requires

focal adjustment. Electronically-controlled lenses greatly

reduce time between measurements.

• Radiant cameras include an Auto Adjust Exposure function to

optimize the imaging system for any environment.

CIE-matched cameras simulate the human eye’s response to various wavelengths of light.

The CIE color-matching functions provide the basis for obtaining quantifiable values of perceived color for scientific color measurement. Radiant imaging colorimeters replicate light intensity per wavelength given by these curves using a tristimulus filter system, adjusting exposure for each filter to ensure absolute measurement to human vision.

one- and four-color calibration (single-color or RGB

emitters); LED and white phosphor LED calibration

• Lensing effects: Distortion calibration (if applicable)

Before distortion calibration After distortion calibration

Things to consider:

• Measurement conditions change. Calibration ensures accurate,

absolute data across users, devices, and environments.

• Radiant cameras automatically apply calibrations for new focal

and aperture settings, removing this burden from the operator.

SPOTLIGHT: Black Mura Testing

In automotive Black Mura testing, lenses can be electronically defocused to meet the required modulation depth percentage (between 50-90%) to remove moiré interference. Refocusing the lens enables the same camera to inspect for small defects like stuck pixels, lines, particles, or surface scratches.

Defocus for moiré removal Refocus quickly for detail inspection

Things to consider:

• Electronically-controlled lenses remove human error by

adjusting to data points entered into the software.

• Locating objects or virtual images at multiple depths requires

focal adjustment. Electronically-controlled lenses greatly

reduce time between measurements.

• Radiant cameras include an Auto Adjust Exposure function to

optimize the imaging system for any environment.

R&D OR PRODUCTION PLATFORMRadiant cameras operate on multiple

platforms to enable flexible control.

Things to consider:

• Complex instrument panels may contain symbols of many

shapes, colors, and locations. Radiant’s imaging systems

can capture and define all symbols in a single measurement.

• Symbols may fall outside of statically-defined POI. Radiant’s

The CIE color-matching functions provide the basis for obtaining quantifiable values of perceived color for scientific color measurement. Radiant imaging colorimeters replicate light intensity per wavelength given by these curves using a tristimulus filter system, adjusting exposure for each filter to ensure absolute measurement to human vision.

SPOTLIGHT: Tristimulus Filter System

CIE-Matched Optical Filters

• Focal Distance: Flat-field

calibration; Image scaling

• Device Spectral Power Distribution (SPD):

Luminance calibration; Color calibrations, such as

one- and four-color calibration (single-color or RGB

emitters); LED and white phosphor LED calibration

• Lensing effects: Distortion calibration (if applicable)

Before distortion calibration After distortion calibration

Things to consider:

• Measurement conditions change. Calibration ensures accurate,

absolute data across users, devices, and environments.

• Radiant cameras automatically apply calibrations for new focal

and aperture settings, removing this burden from the operator.

SPOTLIGHT: Black Mura Testing

In automotive Black Mura testing, lenses can be electronically defocused to meet the required modulation depth percentage (between 50-90%) to remove moiré interference. Refocusing the lens enables the same camera to inspect for small defects like stuck pixels, lines, particles, or surface scratches.

Defocus for moiré removal Refocus quickly for detail inspection

Things to consider:

• Electronically-controlled lenses remove human error by

adjusting to data points entered into the software.

• Locating objects or virtual images at multiple depths requires

focal adjustment. Electronically-controlled lenses greatly

reduce time between measurements.

• Radiant cameras include an Auto Adjust Exposure function to

optimize the imaging system for any environment.

R&D OR PRODUCTION PLATFORMRadiant cameras operate on multiple

platforms to enable flexible control.

Choose where to implement a system. Share and compare data from lab to line.

• Manual or partially-automated for R&D

• Fully automated for production lines

ProMetric® Software comes with every Radiant camera

and includes programming examples for external readout.

TrueTest™ Software provides test sequencing and on-site

training to equip users to modify sequences on their own.

SPOTLIGHT: Automated Test Sequencing Applying multiple tests in an automated sequence results in massive time-savings.

SPOTLIGHT: Characterizing Mura

Radiant’s display test expertise extends into defect families. Our TrueMURA™ Software module includes tests to detect, classify, and grade over 15 types of display mura.

Things to consider:

• Radiant works with major

manufacturers of flat panel,

touch, free-form, head-up,

wearable, virtual reality,

curved, OLED, microLED,

and all other display types.

• Radiant mura algorithms

compute “Just Noticeable

SPOTLIGHT: Auto-POI

Radiant’s “automatic points-of-interest” tool evaluates entire instrument clusters, locating POI dynamically based on light and color.

Luminance Threshold Color Threshold

Static POI: Symbol rotates outside of region

Auto-POI: Region defined by color value

Things to consider:

• Complex instrument panels may contain symbols of many

shapes, colors, and locations. Radiant’s imaging systems

can capture and define all symbols in a single measurement.

• Symbols may fall outside of statically-defined POI. Radiant’s

responsive registration tools dynamically snap to precise

symbol shapes, even when devices are rotated or moved, or

symbols appear in different arrangements.

RADIANT SYSTEM:

SPOTLIGHT: Enhanced Color Calibration

Optional factory color calibration offers out-of-the-box accuracy for:

• Narrow-band sources (LEDs)

• White phosphor LEDs and LED-based components

Users can also leverage ECC to create custom calibrations for:

• Accuracy over a large color space — A single calibration to measure a range of values.

• Ease of use — Import a spectrum or data from a spectrometer, rather than entering reference values.

NO.1 FOR DISPLAY TESTThe number-one provider of display test solutions

worldwide, Radiant is chosen by the leading innovators

in displays—which means we develop the majority of the

industry’s display test algorithms and methods.

CALIBRATIONEach Radiant camera and lens pair

can be calibrated for unique

applications—ensuring consistency

regardless of variation in:

Set tolerances for registration regions based on color coordinates or by drawing shapes directly on the CIE color space.

LIGHT & COLOR THRESHOLDSRadiant software defines regions of

interest based on luminance ranges

or chromaticity coordinates, enabling

precise character evaluation.

Automatic moiré removal eliminates aliasing effects while preserving important image information needed for mura and pixel-level analysis.

• • •

Things to consider:

• Data acquired by Radiant cameras is portable across

systems, ensuring consistency from lab to line.

• Low-resolution and noisy images reduce camera accuracy

and measurement speed. Radiant’s imaging advantages

capture the clearest images for fast in-line image processing.

• TrueTest Software is the leading production platform for light

and color measurement, with an API to control test images on

displays, trigger cameras, and synchronize pass/fail analyses.

OPTICAL CONFIGURATIONS

Lenses designed for advanced measurement tasks allow

users to create optical configurations that leverage the

power of Radiant cameras in a range of applications.

Pair your imaging system with a range of optical accessories to measure new wavelengths of light, view angles, and fields of view.

SPOTLIGHT: Sparkle Measurement

Evaluate the effect of “sparkle” in anti-glare display layers. The Radiant Sparkle Measurement Method quantifies sparkle using a mean pixel-level luminance variation percentage across the display. This value matches human determinations of acceptable display quality, which can be used to set measurable tolerances for films and coatings.

Pinpoint errors at the component level: cell/open cell, backlight unit (BLU), LCD module, cover glass, and films or coatings.

Things to consider:

• Do you know the source of your defect? When a display

reaches final assembly, several materials and processes

have already been applied—some defective or damaging.

Inspection at each layer stops issues at the source.

Example of anti-glare sparkle on LCD displays:

Luminance variation: 2.4% Human Rating: Acceptable

Luminance variation: 4.1% Human Rating: Poor

Radiant cameras measure and calculate correction factors for discrepancies in light output between subpixels in OLED, microLED, and other emissive display technologies.

SPOTLIGHT: Demura

The Radiant “demura” process corrects pixel uniformity in emissive displays. A high-resolution ProMetric system takes a measurement of each display subpixel and calculates the correction factors needed to equalize luminance output. These factors are then applied to each subpixel to adjust output and produce a display with a uniform appearance.

Radiant images of an OLED display before and after demura.

Things to consider:

• Demura correction reduces

waste of “defective” materials.

• Pixel shape, size, color, and

pattern vary from display to

display. Radiant software

dynamically registers all

pixels regardless of variation.

Things to consider:

• Displays in fixed integrations may be viewed off-angle.

Radiant’s FPD Conoscope Lens evaluates the visibility of a

display at view angles to ±70° in every direction at once.

• Achieve more versatility in a single instrument. Switch

between the FPD conoscope and standard lenses to use

Radiant cameras for other display measurements like

uniformity, pixel defects, mura, and more.

IRTUAL & AUGMENTED REALITY

Things to consider:

• Wide fields of view

create immersive

experiences.

Radiant’s AR/VR

lens captures 120°

horizontal FOV,

even at close range.

• Viewed at close proximity, display defects become more

apparent, so testing at the human eye position is crucial.

• With aperture located at the front, Radiant’s AR/VR lens

captures the complete display FOV as seen by the user.

URFACE INSPECTION

Engineered for light measurement, Radiant cameras offer superior imaging to capture subtle defects in high-value assemblies and surfaces.

SPOTLIGHT: “Just Noticeable Differences”

Things to consider:

• Quality doesn’t stop at the display. Radiant’s advanced

vision systems leverage light measurement advantages

to enable surface and assembly inspection beyond the

capabilities of humans and standard machine vision.

JND is the amount of change over an area that is noticeable to a human observer. Radiant software uses a JND value to detect and grade non-uniform areas of light and color in illuminated displays.This process can be extended to inspection of external devicesurfaces and coverglass to identify,classify, and gradethe severity of unknown defects in unknown locations.

Radiant high-resolution imagers capture each display pixel over an area of several sensor pixels.
