  • Patent number: 11899857
    Abstract: A touchpad module includes a base plate, a touch member, a supporting structure and a pressure sensing unit. The touch member is movable toward the base plate. The supporting structure is arranged between the base plate and the touch member. The pressure sensing unit is installed on the touch member. The pressure sensing unit is arranged between the touch member and the base plate. While the touch member is pressed in response to an external pressing force, the touch member is moved downwardly toward the base plate to compress the supporting structure. Consequently, the supporting structure is subjected to deformation, and the touch member has a displacement amount. According to the displacement amount, a magnitude of the pressing force is sensed by the pressure sensing unit, and a pressure sensing signal is outputted from the pressure sensing unit.

A transceiver circuit is arranged to drive the display in a first mode of operation or in a second mode of operation. The first display subpixels include micro light-emitting diodes and/or resonant-cavity light emitting devices. In the first mode of operation, the transceiver circuit provides a forward bias to the first display subpixels, such that the first display subpixels are operable to emit light. In the second mode of operation, the transceiver circuit provides a reverse bias to the first display subpixels, such that the first display subpixels are operable to detect light.

  • Patent number: 11899838
    Abstract: A wearable device comprises a flexible substrate carrying multiple conducting loops which are formed into a zig zag pattern so as to be able to accommodate a stretching of the substrate. The substrate is formed into a glove and the loops positioned such that they are aligned with the anatomical joints. As the anatomical joints move, the loops change shape and accordingly change their inductance—this is measured by the electronics in the glove and used to calculate the joint angles in a processor which transmits the angles to an external computer system. Some of the loops are attached to current drivers in the electronics module, and a magnet positioned close to the loop, providing means for a force to be generated between magnet and loop when the current driver passes current through the loop, thereby providing tactile feedback to the user.

  • Patent number: 11887546
    Abstract: A display pixel is provided that is operable to support hybrid compensation scheme having both in-pixel threshold voltage canceling and external threshold voltage compensation. The display may include multiple p-type silicon transistors with at least one n-type semiconducting-oxide transistor and one storage capacitor. An on-bias stress phase may be performed prior to a threshold voltage sampling and data programming phase to mitigate hysteresis and improve first frame response. In low refresh rate displays, a first additional on-bias stress operation can be performed separate from the threshold voltage sampling and data programming phase during a refresh frame and a second additional on-bias stress operation can be performed during a vertical blanking frame. The display pixel may be configured to receive an initialization voltage and an anode reset voltage, either of which can be dynamically tuned to match the stress of the first and second additional on-bias stress operations to minimize flicker.
