  • Publication number: 20240122025
    Abstract: A display device includes: a pixel defining layer defining openings arranged in first and second directions, the openings forming emission areas in which light emitting elements are disposed to emit light of different colors; a light blocking layer disposed on the pixel defining layer, and defining holes, each overlapping the opening and having a larger diameter than the opening; and color filters disposed on the light blocking layer to overlap the holes and overlap the emission areas. The opening has an opening interval, which is defined as a difference in diameter between the overlapping hole and the opening, in the openings, among homogeneous openings in which the light emitting elements for emitting light of the same color are disposed, the homogeneous openings adjacent in the first or second direction have different opening intervals, and among the homogeneous openings, openings having different opening intervals are at least three types.

  • Publication number: 20220236334
    Abstract: Provided is an apparatus for diagnosing a battery fault, including: a communicator; and a controller electrically connected to the communicator. In particular, the controller is configured to receive history data related to a battery of a vehicle from the vehicle through the communicator, identify a history related to a decrease in a state of charge of the battery and a current consumption of the battery based on the history data, and identify whether the battery is faulty based on the identifying of the history.
