With a remarkable portfolio encompassing 19 patents, his innovations have paved the way for advancements in liquid crystal display devices, elevating the standards of visual technology.

Latest Patents

Among Akira Ishii's notable patents, the liquid crystal display device stands out for its ingenuity. In this invention, a liquid crystal display panel, consisting of a TFT substrate and a counter substrate, is bonded together using a sealing material. Liquid crystal is sandwiched between the substrates, enhancing display quality. A front window with a black border print is meticulously bonded to the liquid crystal display panel using a UV curable resin. This innovation involves filling the liquid crystal by a drop method, ensuring precision. The thickness of both the TFT substrate and counter substrate is reduced to approximately 0.2 mm through polishing. A crucial design feature is the positioning of the inner end of the black border print inside the sealing material's inner end. This design prevents deformation of the counter substrate due to curing stress from the UV curable resin, thereby eliminating yellow discoloration around the display area.
