Patent number: 11017736Abstract: A display device may include a data driver that outputs a previous data voltage and a current data voltage, respectively, at an output terminal, to be applied to a pixel of a display panel in respective time intervals. A switch is controlled to open and close a circuit path between the output terminal and a data line coupled to the pixel. A capacitor stores an overdriving voltage. At least one further switch selectively applies the overdriving voltage to the data line from the capacitor when the circuit path is open and thereby enables a rapid transition of a voltage level of the data line between the previous and current data voltages, when the current and previous data voltages are to differ by more than a predetermined amount. As an example, the rapid transition between the previous and current data voltages may serve to minimize a color mixture phenomenon between pixels connected to a common data line and representing different colors.Type: GrantFiled: July 11, 2017Date of Patent: May 25, 2021Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Boyeon Kim, Wontae Kim, Taegon Im

Patent number: 10948742Abstract: An eye-mounted display includes a scleral contact lens with one or more femtoprojectors that project images onto the user's retina. The scleral contact lens has a non-circular perimeter, for example elongated along the direction of the eye opening. The non-circular shape can result in less slippage and/or rotation of the contact lens relative to the eye. If the contact lens is elongated (compared to traditional circular lenses), then it can contain conductive coils that enclose a larger area. Thus, the lens increases coupling efficiency for power or data transfer. There can also be more space within the contact lens for payloads.Type: GrantFiled: March 5, 2020Date of Patent: March 16, 2021Assignee: Tectus CorporationInventor: Kuang-mon Ashley Tuan
