With a total of four patents to his name, Fujioka's work has had a notable impact on the efficiency and functionality of display panels.
Latest Patents
Among his latest patents is the "Thin film EL display panel drive circuit." This innovation allows for the variation of drive voltage according to changes in the number of emitting picture elements. Another significant patent is the "Driving circuit for thin film EL display device." This device features an EL layer positioned between scanning side electrodes and data side electrodes that cross each other. The design includes a data side driver integrated circuit (IC) with switching elements for charging and discharging, connected to the data side electrodes. Additionally, switching circuits apply modulation voltage to a pull-up common line of the data side driver IC. These circuits are equipped with switches that remove the charge stored in the thin film EL device after light emission, along with a capacitor that stores the removed charge. This innovative approach allows for the reuse of charge in subsequent light emissions, effectively reducing power consumption.
