SAN DIMAS, Calif., May 20, 2011 — Organic LEDs (OLEDs) are being developed for the next generation of displays and light sources. The 308 FPD microscope spectrophotometer from Craic Technologies Inc. is designed to measure and compare the spectral output, intensity and color consistency of each of the microscopic pixels commonly found in OLED devices.
The spectrophotometer measures color and relative intensity on the micron scale, enabling microscopic spatial resolution mapping. It attaches easily to inspection microscopes and probe stations.
OLEDs have an emissive electroluminescent layer that consists of organic molecules in a supporting matrix. For displays, this layer is formed into millions of microscopic pixels in ordered rows and columns. Because different organic compounds are used to generate different colors, pixels with different organic compounds can generate different colors for full-color, high-resolution displays.
The spectrophotometer attaches to the open photoport of a microscope or probe station. It allows the user to acquire images and spectra of microscopic sample areas quickly and rapidly. When added to the appropriate microscope or probe station, it can be used to measure the color and intensity of each pixel of an OLED display. Pixels can then be compared with one another for consistency, and maps of the intensity and color can be generated for each device. The instrument can acquire spectra on the order of a few milliseconds, so entire OLED displays can be mapped quickly and accurately to ensure consistency of color and intensity across the entire device as well as from device to device.
