Abstract: The present disclosure provides a display substrate, a method for manufacturing thereof and a display apparatus. The display substrate includes: a base substrate having a holing area, a display area around the holing area and an isolation area between the display area and the holing area; at least one circle of blocking wall in the isolation area and around the holing area; an encapsulation layer, on one side of a layer where the blocking wall is located away from the base substrate; a first protection layer, on one side of the encapsulation layer away from the base substrate; and a filling layer, on one side of the first protection layer away from the base substrate, in the isolation area, completely covering the at least one circle of blocking wall and at least partially overlapping with the encapsulation layer.

Abstract: A display substrate has a display region and a peripheral region. The display substrate includes a substrate, a first dam, a second dam and a connection portion. The first dam and the second dam are located on a side of the substrate, and are located in the peripheral region. The second dam is farther from the display region than the first dam. A height of the second dam is greater than a height of the first dam. The connection portion is located between the first dam and the second dam. The connection portion connects the first dam and the second dam, and a height of the connection portion is less than the height of the first dam. At least a portion of the first dam, at least a portion of the connection portion and at least a portion of the second dam are of an integrative structure.

Abstract: The invention discloses a novel rapidly foldable electric vehicle comprising a main beam, a rear wheel, a cross beam, a bracket and a forward/backward movable saddle, wherein a pin is arranged at a junction between a lower end of the bracket and the main beam, a supporting post is arranged at the lower end of the bracket, the bracket and the supporting post are rotatably arranged about the pin, an included angle of less than 180° is formed between the supporting post and the bracket, and a towing wheel is arranged at a lower end of the supporting post.
