Latest Patents
Shimokawa's latest patents include a liquid crystal display apparatus that boasts an improved repair success rate. In this innovative design, a pixel electrode is electrically connected to a drain electrode of a thin-film transistor. The drain electrode features a substantial correction site that is narrowed in width. An opening is formed in a specific region of the pixel electrode, overlying the substantial correction site of the drain electrode, ensuring contact with the outer periphery of the pixel electrode. Another significant patent involves a display device that includes unit cells, each comprising a thin film transistor and a pixel, arranged in a matrix form on a display board. This device features first switching elements at the intersections of signal conductor lines and scanning conductor lines, with scanning conductor line drive elements responsible for driving the scanning conductor lines. Additionally, second switching elements are included, which disconnect the scanning conductor line from the scanning conductor line drive element in synchronization with a fall in the level of an input video signal.
