  • Patent number: 11960185
    Abstract: Display data of pixels is updated at different timings. A scan line is connected to a first pixel and a second pixel, a first wiring is connected to the first pixel, and a second wiring is connected to the second pixel. In a first period, a signal for selecting the first pixel and the second pixel is supplied to the scan line. Setting data for setting a state where the display data of the first pixel is updated is supplied to the first wiring, and setting data for setting a state where the display data of the second pixel is updated is supplied to the second wiring. In a second period, a signal for selecting the first pixel and the second pixel is supplied to the scan line. Setting data for setting a state where the display data of the first pixel is not updated is supplied to the first wiring, and the setting data for setting the state where the display data of the second pixel is updated is supplied to the second wiring.

  • Publication number: 20240069398
    Abstract: A display apparatus includes a data generation circuit, a source driver circuit, and a pixel. The source driver circuit is electrically connected to the pixel through first and second wirings. The pixel includes a display device that is a liquid crystal device, a potential of one electrode of the display device can be a potential of the first wiring, and a potential of the other electrode of the display device can be a potential of the second wiring. The image data generation circuit has a function of generating digital image data including first and second data. One of the first and second wirings is made to have a potential corresponding to first data, and the other of the first and second wirings is made to have a potential corresponding to the second_data. The potential of the first wiring and the potential of the second wiring are interchanged.

  • Patent number: 10765439
    Abstract: Provided is a treatment method of being able to improve the obstruction of a biological lumen caused by stenosis of the biological lumen and the stagnation of a secretion. The treatment method includes a disposition step of disposing a dilation portion that can be dilated and deflated, and a collection portion, which is capable of removing a secretion S secreted from a biological lumen from a living body, in a stenosed site occurring in the biological lumen; a dilation step of widening the stenosed site after the disposition step by dilating the dilation portion in the stenosed site after the disposition step; and a removal step of removing the secretion from the living body by a removal portion.

  • Patent number: 10010698
    Abstract: A shaft of a catheter is disclosed, the shaft has a thin portion, which constitutes a distal side of the shaft, a thick portion which is provided further on a proximal side than the thin portion, and a tapered portion which is provided between the thin portion and the thick portion. The tapered portion is formed more flexibly than the thick portion. The thick portion has a first thick portion and a second thick portion which is provided between the tapered portion and the first thick portion. The second thick portion has a smaller outer diameter than the outer diameter of a proximal end of the tapered portion and the outer diameter of the first thick portion, and is formed more flexibly than the first thick portion.
