Latest Patents

Kondou's latest patents include an anti-reflecting membrane and a display apparatus, as well as an optical storage medium and a solar energy converting device. His anti-reflecting membrane is designed to be applied to plates transmitting visible light. It is composed of fine inorganic oxide particles and a binder, featuring a number of pores inside and an arithmetic average surface roughness (Ra) below 6 nm. This invention addresses the challenges faced by conventional thin membranes of aerogel, which, while achieving a low refractive index, often lack the necessary strength for practical applications.

The display apparatus developed by Kondou aims to enhance the quality of liquid crystal displays. It incorporates a third electrode that differs from the common and pixel electrodes. By varying the voltage applied to this third electrode within one frame period, the device can drive the liquid crystal using a strong electric field initially, followed by a uniform horizontal electric field in the latter stage. This innovation helps to prevent image sticking and improves response speed.
