How to Use Imaging Colorimeters to Improve OLED Display Quality

In this article, we discuss the manufacturing challenges that are common in OLED displays, and correction methods that can be used to adjust the output of individual pixels of emissive displays (like OLED, microLED, and others) to ensure uniformity of brightness and color, preventing waste of "defective"...

Matching Human Visual Perception

In this article, learn how photometric and colorimetric technology matches the visual sensitivity of human vision. We discuss the advantages and applications of CCD imaging for light and color measurement, as well as component and surface inspection, that most accurately reflects the human visual experience.

Efficient Measurement of Large Light Source Near-Field Color and Luminance Distributions for Optical Design and Simulation

In this article, we describe a method for the measurement of large light sources in a limited space that efficiently overcomes the physical limitations of traditional far-field measurement techniques. The measurement is performed from within the near-field of the light source, enabling a compact measurement...

Choosing a Measurement System for LED Sources, Luminaires, and Displays

In this article published by Global LEDs/OLEDs, Radiant surveys a number of measurement methods that generate either near-field or far-field models of the LED or luminaire and evaluate their strengths and weaknesses to guide us in selecting the right measurement method for the application.
