Radiant sponsors and leads a technical presentation at the 34th electronic displays Conference (edC) taking place Feb. 26-27 in Nuremberg, Germany. The event is a major forum for the presentation of innovative ideas, approaches, developments and research projects in the area of today’s and future display business.
As part of Session 14 on Day 2 of the conference (Feb. 27), Radiant's Vice President of Product Development, Jens Jensen, will lead a technical presentation outlining the results of lab testing of leading color measurement systems to compare the accuracy of tristimulus filter systems and Bayer pattern filter systems based on CIE color-matching functions. The results are especially poignant for LED, microLED, and other emissive display technologies, which commonly exhibit variability in color from pixel to pixel. Color measurment systems must be able to accurately characterize the color output of these each pixel for a wide range of values based on initial calibration. The results of Radiant's paper will demonstrate how color measurement systems using different filter technology tolerate variation for each color in a display.

Evaluating Tristimulus and Bayer Pattern Color Filter Accuracy for Display Measurement Based on CIE Color-Matching Functions
Jens Jensen, Radiant Vision Systems
The proposed paper presents a study testing color measurement performance of two color imaging systems measuring narrow-band sources (e.g., LEDs and microLEDs): one with tristimulus color filters, the other a Bayer pattern color filter array. Results outline limitations of each system to provide accurate measurement to CIE color coordinates.
