  • Patent number: 10930226
    Abstract: A liquid crystal display device is manufactured at a low cost. In the liquid crystal display device, three sub-pixel electrodes are connected by inter-electrode connection portions to form one pixel electrode. One TFT is connected to the pixel electrode. A screen of a liquid crystal display panel is divided into n (n?2) of areas. Gate signal lines G of each divided area are scanned simultaneously one line at a time in each divided area. A backlight device emits light after completion of the scanning of each divided area.

  • Patent number: 10901057
    Abstract: A magnetic resonance imaging apparatus according to an embodiment includes first generating circuitry and second generating circuitry. The first generating circuitry interpolates a first data string of digital data including envelope information of a radio frequency (RF) pulse to be output, thereby generating a second data string in which a variation amount of digital data adjacent to each other in the first data string is smaller than an upper limit value. The second generating circuitry generates a signal of the RF pulse by combining the second data string generated by the first generating circuitry and information relating to a carrier wave of the RF pulse, and outputs the signal to an RF amplifier.
