Latest Patents

One of Iwayama's notable inventions is the "Chevron-type liquid crystal device having effective display and pattern." This innovative liquid crystal display panel incorporates a pair of substrates featuring scanning and data electrodes, organized into an electrode matrix. Between these electrodes, a chiral smectic liquid crystal is positioned to create multiple smectic layers containing liquid crystal molecules. The design allows for a clearly defined effective display region along with a fixed or semi-fixed pattern display region that surrounds it. A key aspect of this patent is the arrangement of the smectic layers, which are aligned in a direction distinct from the pattern display region to mitigate cell thickness irregularity and liquid crystal voids.

Additionally, Iwayama holds a patent for a "Chiral smectic liquid crystal display and method of selectively driving." In this invention, a ferroelectric liquid crystal device is detailed, showcasing an intricate electrode matrix comprising scanning lines and data lines. It features a systematic approach where a driver sequentially applies signals to these lines to select specific scans, thus enhancing display control. This technology employs a unique dual-phase data signal approach, allowing for precise compensation, which is crucial for optimizing display performance.
