Latest Patents
One of Kaho's latest patents is the "Optical writing type liquid crystal light valve and writing apparatus." This innovative device features a liquid crystal light valve that includes a photoconductive layer situated between a pair of electrodes and a liquid crystal layer. The resistivity of the photoconductive layer decreases when exposed to light, allowing for effective image data writing. By applying a voltage between the electrodes, the crystalline structure of the liquid crystal layer is altered in the light-irradiated areas, enabling precise image data manipulation. The design incorporates a laminate of an amorphous silicon film and an inorganic insulating film, which minimizes carrier injection from the electrode to the amorphous silicon film. The voltage polarity for writing image data is inverted during horizontal scanning, facilitating the writing of black portions on a white background and vice versa. This method allows for data writing on one line while erasing it on the next, enhancing the efficiency of the writing process. Additionally, by implementing periods without voltage during writing, Kaho's invention prevents writing errors caused by stored charges.
