Latest Patents
Yabushita's latest patents include innovative methods and designs for liquid crystal displays. One of his patents focuses on an active matrix liquid crystal display and its manufacturing method. This invention features an electrooptical element that includes a storage capacitance wiring group and collective drawing wiring. During the wet etching of the transparent conductor film of pixel electrodes, all wiring of the storage capacitance wiring group is electrically separated. After the wet etching of the pixel electrodes, all of the storage capacitance wiring group is electrically connected with the collective drawing wiring. This design minimizes the corrosion of the storage capacitance wiring by maintaining a small capacitance value during the wet etching process.
Another significant patent involves a TFT array substrate and a liquid crystal display utilizing this substrate. The manufacturing method described ensures that the interlayer insulating film covers the guard resistance and the short ring. This innovation allows for reduced connection resistance between the picture element electrode and the drain electrode through the interlayer insulating film. The process enables the ITO film to be patterned into a desirable shape without short circuits between assembled terminals in a single etching process.
