Development of ultracompact and ultrathin spatial light modulators for realizing holographic contact lens displays

Citizen Finedevice Co., Ltd. (CFD) is a manufacturer that can handle everything from the development and production of ferroelectric liquid crystals to the production of liquid crystal panels/LCOS panels, and assembly with lenses and other optical components to create a finished module. Recently, we have been developing an ultra-small and ultra-thin liquid crystal panel with high performance for contact lens displays, and by improving the substrate polishing and cutting techniques and the liquid crystal injection process, we have developed the technology to create liquid crystal panels with an outer diameter of 5 mm or less and a total thickness of 0.1 mm or less. In this presentation, we would like to introduce ultra-small and ultra-thin panels that can be used in contact lens displays, as well as the improving performance of other liquid crystal panels.
