Latest Patents
Kiyohara holds a patent for an EL display apparatus. This invention features a data side driving IC that incorporates pull-up and pull-down elements, which are applied with modulating voltages of +½VM and -½VM, respectively. Additionally, a scanning side driving IC is designed with pull-up elements that utilize a positive write voltage of +VW from a positive voltage supply circuit, and pull-down elements that use a negative write voltage of -VW from a negative voltage supply circuit. Each data electrode is driven by a positive voltage of +½VM or a negative voltage of -½VM. The scanning electrodes are controlled to receive a positive write voltage of +VW, a negative write voltage of -VW, or to assume a ground or floating potential. This design allows for high symmetry in driving the data and scanning electrodes, enhancing long-term reliability while simplifying peripheral circuitry.
