Abstract: A display panel includes a display area which has a notch and a non-display area surrounding the display area. The non-display area includes a notched non-display area that surrounds the notch by substantially in half. The display panel also includes an encapsulation cover located at a side of the display layer away from the array layer, and an encapsulant disposed between the array layer and the encapsulation cover. The encapsulant is located in the non-display area and surrounds the display layer. Moreover, the display panel includes an encapsulated metal located in the non-display area. The encapsulated metal is disposed in an array layer. In a laser-sintering process of the encapsulant, the encapsulated metal is used for reflecting laser light. An orthographic projection of the encapsulated metal in the substrate layer has a non-closed pattern, and the encapsulated metal is undisposed in at least a portion of the notched non-display area.

Abstract: A display panel includes a display area, and the display area is disposed with a plurality of data lines extending along a first direction. The display area has a notch, and the boundary of the display area is recessed into the display area in a second direction to form the notch. The display area includes a first display area and two second display areas. The display panel also includes a non-display area disposed around the display area. The non-display area includes a first non-display area and two second non-display areas located in the notch. The first non-display area extends along the first direction, and is adjacent to the first display area in the second direction. In the first direction, each of the second non-display areas is adjacent to one of the second display areas. The display panel also includes a drive circuit, and the drive circuit includes a plurality of shift registers. The second direction intersects with the first direction. In the second direction, the first display area is located at one side of the notch. In the first direction, the two second display areas are located at two sides of the notch respectively, and the two second display areas are adjacent to the first display area. The display area includes a plurality of signal lines extending along the second direction, and one shift register is electrically connected to at least one signal line. The second non-display areas are disposed with the shift registers, and the shift registers disposed in the second non-display areas are electrically connected to the signal lines located in the first display area.
