Latest Patents
Sakaguchi's latest patents include a pixel circuit, a display device, and an electronic apparatus. The pixel circuit is designed to prevent slight light emission of an organic EL element due to leakage current from a driving transistor. This innovative circuit features a light-emitting element that emits light at luminance corresponding to the amount of current. It also includes a first capacitance, which is a metal insulator metal (MIM) capacitance, and a second capacitance, which is a metal insulator semiconductor (MIS) capacitance, disposed in parallel to the light-emitting element.
Another notable patent is for an electro-optical apparatus that includes selector switches. Each selector switch is provided for each data line, with one data line disposed for each pixel column of a pixel section that includes pixel circuits arranged in a matrix form. Each pixel circuit consists of a drive transistor and a light-emitting element that emits light at luminance commensurate with the magnitude of the current supplied via the drive transistor. The selector switches are responsible for writing an input data signal to the data lines and a correction potential for adjusting the threshold voltage of the drive transistor.
