Visibly Perfect: Test & Correction Solutions for MicroLED, OLED, and Other Displays

Development in the global display industry has entered a critical period with microOLED, miniLED, and microLED setting off a new wave of technological progress. Because each pixel in these emissive displays is self-illuminating, output differences between pixels may occur, resulting in non-uniform brightness and color across the display. To address this and other visual quality issues, manufacturers can apply scientific photometric imaging systems in R&D and production to measure display output and correct pixel-level values for visibly perfect display quality.

Radiant's portfolio of display test & correction solutions is designed for both R&D and high-throughput inspection applications including pixel-level measurement and calibration (demura). Combining ProMetric® Imaging Colorimeters and Photometers with TrueTest Software, these automated visual inspection systems help to increase efficiency, control production costs, and ensure visual quality of consumer electronics displays from large panels to smart devices to virtual & augmented reality headsets.

Watch this video to explore Radiant's solutions for:

  • Emissive displays: OLED, miniLED, microLED, microOLED
  • Pixel-level measurement and correction (demura) 
  • Capturing precise luminance & chromaticity values at each subpixel to adjust pixel output and ensure visibly perfect display uniformity at all brightness levels
  • Pixel characterization using microscope lenses
  • In-headset measurement for evaluation of AR/VR displays
