Patent number: 11963318Abstract: A supporting plate and a foldable display device are provided. The supporting plate includes at least one bending region and non-bending regions. The bending region includes two semi-bending regions bent symmetrically along a bending axis. Any of the semi-bending regions includes an internally bending region and an externally bending region. The internally bending region is located on an end away from the non-bending regions. The externally bending region is located on an end close to the non-bending regions and has a bending direction opposite to the internally bending region. The semi-bending regions include a plurality of openings spaced apart. A distribution density of the openings in the internally bending region is greater than a distribution density of the openings in the externally bending region.Type: GrantFiled: April 28, 2021Date of Patent: April 16, 2024Assignee: Wuhan China Star Optoelectronics Semiconductor Display Technology Co., Ltd.Inventors: Yafei Fu, Yapeng Cheng

Patent number: 11406032Abstract: A foldable flexible display device, with a design of disposing reinforcing structures on lower surfaces of a support plate, when a front surface of a flexible display device is subjected to an external impact, the reinforcing structures are able to support the sinking flexible display panel and the displacement of the flexible display device is reduced so that the back cover under the support plate is not in contact with the sinking flexible display panel. This can obviously improve the impact condition of the flexible display panel and the impact resistance of the flexible display panel, thereby preventing the flexible display panel failure caused by stress concentration.Type: GrantFiled: December 3, 2019Date of Patent: August 2, 2022Assignee: Wuhan China Star Optoelectronics Semiconductor Display Technology Co., Ltd.Inventors: Mingyong Xia, Yapeng Cheng

Patent number: 11394816Abstract: A flexible organic light-emitting diode (OLED) mobile phone module of the present disclosure is provided, including a mid-frame, a flexible OLED panel attached to the mid-frame, a back cover connected to the mid-frame, and a buffer layer disposed between the mid-frame and the back cover. The buffer layer is configured to absorb an impact force exerted on the flexible OLED panel. When the flexible OLED panel is impacted by a steel ball or the like, the impact force can be transmitted to the buffer layer through the mid-frame, and the buffer layer can absorb most of energy, so that no sharp impact occurs between the mid-frame and the back cover, thereby protecting the flexible OLED panel and improving impact resistance of the flexible OLED mobile phone module.Type: GrantFiled: December 12, 2018Date of Patent: July 19, 2022Assignee: WUHAN CHINA STAR OPTOELECTRONICS SEMICONDUCTOR DISPLAY TECHNOLOGY CO., LTD.Inventors: Bao Chen, Yapeng Cheng
