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.
