Avionic engineers are increasingly replacing CRTs with LCDs in both head-up displays and head down displays. Indeed, LCDs have made considerable progress with regards to adequate brightness, dimmability and reliability. Image quality issues in terms of resolution, viewing angle, gray scale and color gamut have also been improved. However, much more progress is required and manufacturing cost cannot be ignored. Quantum Vision is actively developing an alternate approach, the resonant microcavity anode. This emissive component is based upon rugged thin film phosphors capable of generating high brightness and high resolution images. Current theoretical predictions indicate that resonant microcavities can lead to an order of magnitude increase in brightness while having a cost profile consistent with high volume products.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
