Latest Patents
Yukawa's latest patents include a liquid crystal display element and a method for treating defective pixels. In his first patent, he describes an active liquid crystal display element that operates in a normally white mode. This invention features a shorting metal layer that overlaps each pixel electrode and an adjacent source bus. Weld metal layers are formed in the overlapping portions, allowing the pixel electrode of a defective pixel to be connected to the corresponding source bus through laser beam irradiation. This method effectively addresses defective pixels, turning them into black defects during operation.
His second patent focuses on an active matrix liquid crystal display device that incorporates an internal short circuiting bus. This bus is strategically formed across source and gate buses outside the display region, where thin film transistors and pixel electrodes are arranged in a matrix. High resistance coupling elements connect the internal short circuiting bus to the source and gate buses, improving the overall functionality of the display device.
