Patent number: 11852921Abstract: An alignment deviation detection method and apparatus of a display panel, a data compensation method and apparatus. The method includes: providing a first data signal for causing the dimming screen to display an alignment dimming picture including a first alignment pattern; providing a second data signal for causing the display screen to display an alignment display picture including a second alignment pattern; under a control of the first data signal, making the dimming screen display the alignment dimming picture, and under a control of the second data signal, making the display screen display the alignment display picture; according to a display situation of the second alignment pattern, determining an alignment state between the display screen and the dimming screen. An orthographic projection of the second alignment pattern on the dimming screen is preset to be at least partially aligned with and at least partially deviated from the first alignment pattern.Type: GrantFiled: March 27, 2020Date of Patent: December 26, 2023Assignees: BEIJING BOE OPTOELECTRONICS TECHNOLOGY CO., LTD., BOE TECHNOLOGY GROUP CO., LTD.Inventors: Yanhui Xi, Tiankuo Shi, Yan Sun, Xiaomang Zhang, Yifan Hou, Xin Duan, Wei Sun, Ming Chen, Wenchieh Huang, Shaoru Zhang

Publication number: 20230410761Abstract: A display apparatus and a driving method therefor. The driving method includes: determining a gaze area and a non-gaze area of a user on a display apparatus in real time; and driving the gaze area for image displaying at a first resolution, and driving the non-gaze area for image displaying at a second resolution, wherein the first resolution is higher than the second resolution. By means of the display apparatus, image resolution can be adjusted according to different areas, so as to realize high-resolution image display in a display area at which a user gazes and realize low-resolution image display in other areas, thereby reducing power consumption and achieving reasonable allocation of resources on the premise of ensuring the user experience.Type: ApplicationFiled: November 20, 2020Publication date: December 21, 2023Inventors: Shaolei ZONG, Jigang SUN, Weixin JIANG, Bin WANG, Wei SUN, Xin DUAN, Shuhuan YU, Kexin HAO, Jiaqi FAN, Zhaoyun GU, Shaoru ZHANG, Tieshi WANG, Kuanjun PENG, Xue DONG, Wei QIN, Weixing LIU

Patent number: 11822203Abstract: A display panel and control methods thereof are provided. In one example, the display panel includes, a first substrate and a second substrate opposite to each other, and a solution encapsulated between the first substrate and the second substrate. In some examples, the solution includes opaque charged particles. In some examples, the first substrate includes a first electrode, the first electrode including a plurality of discrete sub-electrodes, and the second substrate includes a second electrode. Further, the control method may include adjusting an electric field between each of the plurality of discrete sub-electrodes and the second electrode, causing the opaque charged particles to undergo a gathering motion or a scattering motion.Type: GrantFiled: June 25, 2019Date of Patent: November 21, 2023Assignees: BEIJING BOE OPTOELECTRONICS TECHNOLOGY CO., LTD., BOE TECHNOLOGY GROUP CO., LTD.Inventors: Qingqing Ma, Shuo Li, Chao Tian, Zhe Wang, Xiang Yuan, Wenyuan Xi, Yinan Gao, Rui Xu, Min Wang, Fang Zhang, Qidong Sun, Shaoru Zhang
