Latest Patents
One of Hashido's latest patents involves electronic equipment and flexible printed circuits. In this invention, a shield layer is selectively formed on the front surface of a base film with insulating properties. This design allows for the formation of a wiring layer on the rear surface of the base film, with connector connection terminals and mounting terminals selectively provided on the wiring layer. The liquid crystal display device is designed to be housed in a set housing, connecting a TFT array substrate and a control board via a flexible printed circuit (FPC) with the described structure. The shield layer is positioned to oppose the inner surface of the housing, maintaining an insulating relationship with the drive circuit while being electrically connected to a portion of the housing through the first ground wiring portion.
Another notable patent focuses on a display device where signal lines supply signal currents to pixel circuits containing light-emitting elements. A signal line driving circuit generates a signal current corresponding to image data by switching bit weighting currents from current source circuits for each bit of the image data. Each current source circuit can correct the level of the bit weighting current based on a reference current supplied from a reference current line. This innovation helps suppress variations in signal currents among the signal lines, thereby reducing unevenness in emission luminance.
