Radiant CEO Doug Kreysar presents an improved pixel-level measurement method to ensure accuracy for OLED, microLED correction at the online Display Week Symposium. Registered attendees can view the broadcast online beginning Thursday, Aug. 6.

Radiant Vision Systems, a leading provider of photometric imaging solutions for light and display measurement, announces that it will present a technical paper during the 2020 Display Week Symposium taking place online from August 3-7. The Symposium is one of several events planned over the course of Display Week 2020 including a virtual technical program and exhibition organized by The Society for Information Display (SID). Doug Kreysar, Chief Executive Officer at Radiant Vision Systems, will present the company’s paper titled “Fractional Pixel Method for Improved Pixel-Level Measurement and Correction (Demura) of High-Resolution Displays” authored by Kreysar, Gary R. Pedeville (Senior Principal Engineer), and Joshua H. Rouse (Senior Optical Software Engineer III) from Radiant. The presentation will be available for registered attendees to view online in Session 71: Spatial Uniformity beginning Thursday, August 6.

“Display resolution and pixel density continue to increase dramatically, and so does the importance of measuring displays from the pixel level,” says Kreysar. “Technologies like OLED, mini-, and microLED are illuminated by their emissive pixels and subpixels, which can vary in output. This variation results in nonuniform brightness and color across the display, making measurement and correction processes a critical part of quality control. Measuring the characteristics of individual display pixels, however, has become more challenging for image-based measurement technology, which must apply several sensor pixels per display pixel for accurate measurement. A new fractional-sensor-pixel measurement method was developed by Radiant to improve the accuracy of image-based measurements specifically for ‘demura’ or pixel uniformity correction applications. This method enables highly flexible display pixel registration to ensure accurate calculation of display pixel correction factors to improve display uniformity.”
