Patent number: 11621286Abstract: Provided are a display panel and a display device. The display panel includes a first display area and a second display area. The first display area at least partially surrounds the second display area, and the second display area is configured to provide a photosensitive element. The first display area and the second display area are each provided with multiple sub-pixels. Each of the multiple sub-pixels includes a pixel circuit and a light emitting element. In each of the first display area and the second display area, active layers of the pixel circuits of the sub-pixels in each column have discontinuity points. The discontinuity point is located between respective two adjacent sub-pixels in the same column, or is located within each sub-pixel.Type: GrantFiled: May 6, 2022Date of Patent: April 4, 2023Assignee: Wuhan Tianma Micro-Electronics Co., Ltd.Inventors: Yawei Wang, Ding Zhang, Huanxi Zhang

Patent number: 10795063Abstract: A transflective and non-rectangular display panel and a display device are provided. The non-rectangular display panel includes a display region, a non-display region surrounding the display region, multiple pixels including multiple sub pixels, and a light shielding layer. There is a first boundary between the display region and the non-display region, and a region surrounded by the first boundary and the display region is non-rectangular. Each of the multiple pixels includes at least three of the multiple sub pixels. An open region of each of the multiple sub pixels has a transmissive region and a reflective region. The multiple pixels include normal pixels in the display region and abnormal pixels passed through by the first boundary. In each of the abnormal pixels, each of the transmissive region and the reflective region is partially blocked by the light shielding layer and partially emits light therefrom.Type: GrantFiled: October 30, 2018Date of Patent: October 6, 2020Assignee: SHANGHAI TIANMA MICRO-ELECTRONICS CO., LTD.Inventors: Baiquan Lin, Kerui Xi, Ming Xie, Huanxi Zhang, Min Zhang
