  • Patent number: 11244615
    Abstract: A display with a pixel circuit for driving a current-driven emissive element includes a feedback capacitor in series between the emissive element and a programming node of the pixel circuit. During driving, variations in the operating voltage of the emissive element due to variations in the current conveyed through the emissive element by a driving transistor are accounted for. The feedback capacitor generates voltage adjustments at the programming node that correspond to the variations at the emissive element, and thus reduces variations in light emission. A reset capacitor connected to a select line is selectively connected to the gate terminal of the driving transistor and resets the driving transistor prior to programming. The select line adjusts the voltage on the gate terminal to reset the driving transistor by the capacitive coupling of the select line to the gate terminal created by the reset capacitor.

The AMOLED pixel driving circuit is disposed with a voltage switching module corresponding to each row of sub-pixels, and the voltage switching module is connected to a corresponding row of sub-pixels and scan line corresponding to the row of sub-pixels. The scan signal on the scan line controls the corresponding voltage switching module to provide different power supply voltages to the row of sub-pixels when the switching TFTs in the corresponding row of sub-pixels are turned on and off, thereby compensating for the voltage difference change caused by the parasitic capacitance between the drain and the gate of the switching TFT when the switching TFT changes from on to off, ensuring a stable current flowing through the OLED, and improving the display consistency of the sub-pixels to ensure display quality.

  • Patent number: 11231771
    Abstract: A virtual reality (VR) system comprising a head-mounted display (HMD) and handheld controller set is enhanced to provide a more realistic end user VR experience, e.g., for boxing or other interactive training. In this approach, and in lieu of simply establishing a boundary area for the VR experience, the user also maps a position of a real-world object into a reference frame of the VR environment. This mapping is facilitated using the handheld controller itself, e.g., as positioned in a backwards-facing manner on the user's forearm. The real-world object is then simulated in the 3D VR environment as rendered by the VR HMD, and the user interacts with the real-world object (or its simulation) to provide a more enjoyable and useful interactive experience.
