  • Patent number: 11912217
    Abstract: A vehicle is positively charged with static electricity due to an external factor. The vehicle includes a battery, a static eliminator sheet, and a holding member. The battery includes at least one cell, an electrolyte, a resin case, and negative and positive terminals. The resin case accommodates the components and electrolyte of each cell. The negative terminal is grounded to the vehicle body. The positive terminal is supplied with electric power from a charger. The static eliminator sheet is made of a material on a positive side of a triboelectric series with respect to a material of the resin case. The holding member holds the static eliminator sheet and the resin case in contact with each other. The holding member holds the battery at a predetermined location of the vehicle body in a state where the resin case and the static eliminator sheet are slidable due to vehicle body vibrations.

  • Patent number: 11762247
    Abstract: Provided is a display device including a display panel which allows a curvature portion thereof to be narrowed near a terminal portion even when circuit blocks are arranged in the curvature portion. For a data line in the form of a polyline consisting of a plurality of short straight line segments in a first curvature portion 12a of a display panel 10, as the distance from a terminal portion 16 increases, the slant angle of each straight line segment increases, the number of data lines d decreases, and hence the width of a data line area decreases. Accordingly, the number of unit circuit blocks 70 in a parallel circuit block 80 disposed in a circuit area can be increased by widening the circuit area in proportion to the decrease in the width of the data line area.

  • Publication number: 20230024395
    Abstract: In a display device having a non-rectangular display unit, occurrence of a difference in luminance between a region with a high load and a region with a low load is suppressed. A region inside the display unit is segmented into a high-load region with a high load on horizontal scanning lines (an initialization control line and a write control line) and a low-load region with a low load on horizontal scanning lines. An initialization control line and a write control line that are disposed in the high-load region are driven by a discharge driver and a scan driver, respectively. An initialization control line and a write control line that are disposed in the low-load region both are driven by, for example, the discharge driver.

  • Patent number: 11436980
    Abstract: Provided is a display device including an irregularly shaped display panel that allows a frame area to be narrowed by utilizing the frame area in a cutout portion. Some emission circuits that respectively correspond to scan circuits arranged in a first curvature portion are arranged in a part of a second side portion that is near the first curvature portion, and remaining emission circuits are arranged in a first notch side portion. Accordingly, the emission circuits arranged in the first notch side portion have lines connected to second emission control lines in a second display area from the first notch side portion side, resulting in a fewer number of lines extending into the first curvature portion.
