Request InfoUniversal Display Corp.Universal Display Corp. has unveiled its Pholed phosphorescent organic LED (OLED) materials that enable OLEDs to attain up to four times greater efficiencies. Using the principle of electrophosphorescence, the technology converts up to 100% of the electrical energy in an OLED into light. The materials generate less heat and provide scalability to larger sizes based on reduced power losses and enhanced light output. A 2.2-in. full-color active-matrix Pholed operating at a brightness of 200 cd/m2 consumes only 125 mW under video-mode conditions, with illumination of 30% of the pixels.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra March 2023 IssueLED Diffuse Bar LightsThe LB series of LED diffuse bar lights from CCS Inc. are designed for brightfield, backlighting, wide-area uniformity, and diffuse dome illumination in image processing applications.
