Devices and materials for next-generation broadcasting

Summary

  We continued researching elemental technologies of imaging, recording and display. For imaging technologies, we conducted research on 3D integrated imaging devices that could be applied to advanced imaging devices in the future, RGB-stack-type image sensors for compact, lightweight single-chip color cameras, and solid-state image sensors overlaid with multiplier films using a new structure for an 8K camera with higher sensitivity. For recording technologies, we conducted R&D on multi-level holographic memory to achieve a recording system with a very large capacity and high transfer rate for the long-term storage of 8K video. We also researched a high-speed magnetic recording device with no moving parts to achieve a high reliability and began investigating a recording method using novel magnetic materials. For display technologies, we worked to identify the principle of longer lifetime and higher color purity to realize a flexible OLED display. We also researched ways to improve the quality of a semiconductor film by a solution method to produce a large flexible display. We also progressed with our R&D on thin-film transistors (TFTs), which are driving elements of pixels, to increase the image quality and lower the power consumption of sheet-type displays.
