  • Patent number: 11482183
    Abstract: 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.

  • Patent number: 11468640
    Abstract: A display system includes a head-mounted display configured to project light, having different amounts of wavefront divergence, to an eye of a user to display virtual image content appearing to be disposed at different depth planes. The wavefront divergence may be changed in discrete steps, with the change in steps being triggered based upon whether the user is fixating on a particular depth plane. The display system may be calibrated for switching depth planes for a main user. Upon determining that a guest user is utilizing the system, rather than undergoing a full calibration, the display system may be configured to switch depth planes based on a rough determination of the virtual content that the user is looking at. The virtual content has an associated depth plane and the display system may be configured to switch to the depth plane of that virtual content.

  • Patent number: 11467685
    Abstract: Embodiments disclosed herein relate to a touch display panel and a touch display device. By arranging a shielding structure, which is connected to a touch electrode in a region where a touch line and a data line overlap each other or is applied with a shielding signal corresponding to a touch driving signal from an outside circuit, between the touch line and the data line, it is possible to prevent direct capacitance from being formed between the touch line and the data line, and to prevent the capacitance formed due to the data line from causing noise on a touch sensing signal. In addition, by arranging a touch load reduction layer between the shielding structure and the touch line, it is also possible to reduce the capacitance between the touch line and the data line arranged in the horizontal direction, thereby improving touch sensing performance.

  • Patent number: 11392248
    Abstract: Disclosed herein are structures, devices, and systems for detecting touch and force inputs at multiple sensing locations on a surface of an electronic device using waveguide-based interferometry. A laser light source, such as a VCSEL, inserts light into a waveguide positioned adjacent to the sensing locations, and an input at a sensing location alters the inserted light in the waveguide allowing for determination of the input's touch or force at the sensing location. Wavelength modulation of the inserted light allows isolation in frequency of the signals from each sensing location. Optical phase locking can be used to lock an absolute distance beat frequency corresponding to a stationary reference point in the waveguide.
