Publication number: 20230352497Abstract: A display may have one or more bent portions. To increase the magnitude of curvature in a display and/or to allow for compound curvature in the display, a display panel may be partially formed in a planar state. The partial display panel is then bent to have desired curvature. After the partial display panel is bent, additional display components that are susceptible to damage during the bending process may be added to complete the display panel. A flexible printed circuit may be formed directly on the display panel using precise deposition of conductive material. By forming the flexible printed circuit layer-by-layer directly on the display panel, no substantive pressure needs to be applied to the display panel. Electrical connections may therefore be made to the display panel in regions of the display with high levels of curvature and/or with compound curvature without causing front-of-screen artifacts for the display panel.Type: ApplicationFiled: March 1, 2023Publication date: November 2, 2023Inventors: Meng-Tse Chen, Anshi Liang, Arnoldus A Barlian, Bayu A Thedjoisworo, Boris A Russ, Chun-Hsien Lee, Chun-Lan Wu, Han-Chieh Chang, Jiming Yu, Marc J DeVincentis, Nathan K Gupta, Paolo Sacchetto, Paul S Drzaic, Zhen Zhang, Ziyang Zhang

Patent number: 11756505Abstract: Systems, methods, and devices are provided for providing intra-frame luminance scaling to avoid drawing excessive power while still providing exceptional brightness. An instantaneous average pixel luminance of an electronic display may be determined. The instantaneous average pixel luminance may correspond to an amount of light currently being emitted by the electronic display due to a previous image frame and a current image frame. Based at least in part on the instantaneous average pixel luminance, the luminance of a subset of pixels of image data of the current image frame may be adjusted, thereby allowing the electronic display to operate at a relatively high brightness level without exceeding a power limit.Type: GrantFiled: March 30, 2021Date of Patent: September 12, 2023Assignee: Apple Inc.Inventors: Yang Xu, Jie Won Ryu, Kingsuk Brahma, Koorosh Aflatooni, Marc Joseph DeVincentis, Mohammad Ali Jangda, Paolo Sacchetto, Shengkui Gao, Sinan Alousi, Yafei Bi, Chun Lu

Publication number: 20230197020Abstract: This disclosure provide various techniques for tracking emission profiles on an electronic display. An emission profile may be applied to the electronic display in order to illuminate certain pixels and deactivate (e.g., turn off) certain pixels in the electronic display to facilitate refreshing (e.g., programming with new image data) the deactivated pixels. A real-time row-based average pixel level or average pixel luminance calculation architecture may track the one or more EM profiles to accurately model EM profile behavior, which may enable accurate calculation of the average pixel level or average pixel luminance of the electronic display at any one point in time. The accurate average pixel level or average pixel luminance calculations effectuated by the EM profile tracking may be used to reduce the IR drop, improve real-time peak-luminance control, and improve the performance of under-display sensors, among other advantages.Type: ApplicationFiled: November 16, 2022Publication date: June 22, 2023Inventors: Shengkui Gao, Jie Won Ryu, Kingsuk Brahma, Marc J DeVincentis, Mohammad Ali Jangda, Paolo Sacchetto, Weijun Yao, Yafei Bi, Yang Xu, Yue Jack Chu, Zhe Hua
