Publication number: 20250048790Abstract: A display panel and manufacturing method thereof are provided. The display panel includes a first display area and a second display area surrounding the first display area. The display panel includes: a first substrate, including base islands; light-emitting elements arranged on the first substrate; and a second substrate set on the light-emitting elements. The second substrate includes grooves arranged in the first display area. These grooves can increase the elasticity and stretchability of the second substrate in the first display area, making a stretch film in this area more easily stretchable and deformable, reducing stress concentration. This design aims to prevent excessive force and deformation in a middle part when the display panel is stretched upwards, thus minimizing stress concentration in this area. By allowing a smoother stretch in the first display area, it prevents issues of uneven display effects and abnormal screen problems.Type: ApplicationFiled: November 29, 2023Publication date: February 6, 2025Applicant: Shenzhen China Star Optoelectronics Semiconductor Display Technology Co., Ltd.Inventors: Hao CHEN, Rui ZHAO, Weiji ZHANG
