Patent number: 10036834Abstract: The present invention provides a curved display device, and relates to the field of display technology. The curved display device comprises a plane display panel and a gradient index lens provided at light exit side of the plane display panel, wherein the gradient index lens makes light exiting from the plane display panel converge toward a center of display surface of the curved display device. In the present invention, by adding a gradient index lens to a traditional plane display panel and using refraction effect of light by the gradient index lens, curved display is achieved without curving the display panel, thus poor display caused by curving the display panel is effectively avoided.Type: GrantFiled: July 17, 2015Date of Patent: July 31, 2018Assignees: BOE TECHNOLOGY GROUP CO., LTD., BEIJING BOE DISPLAY TECHNOLOGY CO., LTD.Inventors: Dan Su, Jun Wu, Jieqiong Wang, Wenhai Cui

Patent number: 9741304Abstract: The application relates to a shift register unit and a driving method thereof, a shift register circuit and a display apparatus. The shift register unit may include a gate starting terminal, a first clock terminal, a second clock terminal, a reset terminal, a low level terminal, a gate output terminal, a storage capacitor, a charging module, an output control module and a reset module. In the shift register according to the present application, since the reset operation is under control of the second transistor and the fifth transistor both, an improper reset operation will not occur, even if the signal at the reset terminal is unstable.Type: GrantFiled: March 27, 2015Date of Patent: August 22, 2017Assignees: BOE TECHNOLOGY GROUP CO., LTD., BEIJING BOE DISPLAY TECHNOLOGY CO., LTD.Inventors: Shulin Yao, Seung Min Lee, Zhihua Sun, Xingji Wu, Wenhai Cui, Baoyu Liu
