Abstract: A display substrate, including a substrate having multiple sub-pixel regions, at least one sub-pixel region includes: a first electrode and a second electrode on the substrate and insulated from each other, the second electrode being located on a side of the first electrode away from the substrate; the second electrode includes multiple electrode bars arranged in parallel along a first direction, a first slit is formed between every two adjacent electrode bars in any second electrode; in the first direction, a width of the electrode bar is smaller than that of the sub-pixel region each sub-pixel region includes at least three electrode bars; a ratio of a width of at least one electrode bar to that of the sub-pixel region ranges from 0.06 to 0.3, and one of the first electrode or the second electrode is a pixel electrode, and the other is a common electrode.

Abstract: A vehicle body floor assembly for a vehicle includes a vehicle body mounting structure; and a battery pack, the battery pack including a battery module and a housing, the battery module being provided in the housing, the housing being connected to the vehicle body mounting structure, and at least a portion of the structure of the housing being configured as a vehicle body floor of the vehicle. The structure enables an integration level of a vehicle body and the battery pack to be higher. In addition, also provided is a vehicle having the vehicle body floor assembly.

Abstract: The present disclosure discloses a battery module, a power battery, and a vehicle. The battery module includes a plurality of cell layers laminated on each other and a fixation bracket. Each cell layer includes a plurality of cells arranged in parallel. Each cell has an explosion-proof opening. For every two adjacent cell layers of the cell layers, more than half the number of the explosion-proof openings in one cell layer face towards a first direction, and more than half the number of the explosion-proof openings in the other one cell layer face towards a second direction. The first direction is different from the second direction. The fixation bracket is located at each of two sides of the cell layers. Each of both ends of each cell is fixed to the fixation bracket that is on a same side as the end.

Abstract: An array substrate manufacturing method includes forming a plurality of first lead lines, a plurality of pixel electrodes, and a plurality of connecting lines over a substrate. Each first lead line is insulated from any pixel electrode, and each connecting line is insulated from any first lead line and is configured to electrically couple at least two pixel electrodes such that a set of pixel electrodes electrically coupled by each set of connecting lines substantially form an equivalent lead line. The method further includes detecting whether there is a short circuit between one equivalent lead line and a first lead line, and severing each of the plurality of connecting lines such that any two of the plurality of pixel electrodes are not electrically coupled.
