Patent number: 10559597Abstract: 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.Type: GrantFiled: December 26, 2018Date of Patent: February 11, 2020Assignee: WUHAN TIANMA MICRO-ELECTRONICS CO., LTD.Inventors: Bo Li, Tianqing Hu, Zhaokeng Cao
