  • Publication number: 20240113260
    Abstract: A display device includes a display area where an image is displayed, a non-display area disposed adjacent to the display area, a first sub-pixel disposed in the display area, and a second sub-pixel disposed adjacent to the first sub-pixel in the display area. Each of the first sub-pixel and the second sub-pixel includes a plurality of alignment electrodes spaced apart from each other, and a plurality of light emitting elements disposed between the plurality of alignment electrodes. Each of the plurality of light emitting elements includes a first end having a first polarity, and a second end having a second polarity different from the first polarity. An orientation of the light emitting elements in the first sub-pixel and an orientation of the light emitting elements in the second sub-pixel are symmetrical. The first sub-pixel includes an identification pattern for distinguishing the first sub-pixel from the second sub-pixel.

  • Publication number: 20240067006
    Abstract: A method for charging a micromobility and a charging stand therefor are provided. The charging stand includes a power device that supplies power, a mounting part including a charging part and a holding part configured to dock with at least one micromobility, a power conversion device including at least one converter or an inverter, and a control device that executes an operation for charging the at least one micromobility based on that the mounting part is mounted on the at least one micromobility. The control device receives power supplied from outside by means of the power device, converts the supplied power into a specified DC voltage, outputs at least a portion of the specified DC voltage to the charging part, converts the specified DC voltage into a specified AC voltage, and outputs at least a portion of the specified AC voltage to the charging part.
