  • Patent number: 11828260
    Abstract: An internal combustion engine ignition device includes an ignition coil, an ignition plug, a main ignition circuit, and an energy input circuit. A first switching element of the main ignition circuit performs energization and interruption of energization to a first coil part of a primary coil to generate an induced electromotive force using a DC voltage. A second switching element of the energy input circuit performs energization and interruption of energization to a second coil part of the primary coil to keep a discharge current in a secondary coil within an intended range directly using the DC voltage, after the induced electromotive force has been generated. A soft-off circuit of the energy input circuit slows a turn-off speed of the second switching element.

  • Patent number: 11501729
    Abstract: A source driver includes a data latch unit that outputs acquired pixel data, a gradation voltage conversion unit that acquires the pixel data outputted from the data latch unit and converts the pixel data to gradation voltages, an output unit that amplifies and outputs the gradation voltages to source lines, and a timing control unit that controls the timing of the output of the pixel data from the data latch unit. The timing control unit performs control such that the longer a source line is from a source driver to a pixel column, the smaller the timing difference is between acquisition of the pixel data by the data latch unit and the output of the pixel data.
