    Abstract: An integrated touchscreen can include light emitting diodes or organic light emitting diodes (LEDs/OLEDs), display chiplets and touch chiplets disposed in a visible area of the integrated touch screen. For example, the LEDs/OLEDs, display chiplets and touch chiplets can be placed on a substrate by a micro-transfer tool. The integrated touchscreen can also include electrodes disposed in the visible area of the integrated touch screen. The electrodes can be capable of providing display functionality via the one or more display chiplets during display operation (e.g., operating as cathode terminals of the LEDs during the display operation) and capable of providing touch functionality via the touch chiplets during touch operation (e.g., touch node electrodes can be formed from groups of the electrodes and sensed). In some examples, the touch node electrodes can be formed and coupled to touch chiplets via the display chiplets.

    Abstract: A touch sensing system is disclosed. The touch sensing system includes a guard signal generation chip operating in a first power domain referenced to a first voltage, the guard signal generation chip configured to generate a guard signal. A touch sensing chip operates in a second power domain, different from the first power domain, referenced to the guard signal, the touch sensing chip configured to sense touch at one or more touch electrodes included in a touch sensor panel operating in the second power domain referenced to the guard signal, and the touch sensing chip a different chip than the guard signal generation chip. A voltage regulator is configured to selectively regulate a voltage of the guard signal at the touch sensing chip.

    Abstract: A transmitter device (202) for an inductive energy transfer system can include a DC-to-AC converter (502) operably connected to a transmitter coil (504), a first capacitor (C P1 ) connected between the transmitter coil (504) and one output terminal (506) of the DC-to-AC converter (502), and a second capacitor (C P2 ) connected between the transmitter coil (504) and another output terminal (508) of the DC-to-AC converter (502). One or more capacitive shields can be positioned between the transmitter coil (504) and an interface surface (214) of the transmitter device (202). A receiver device (204) can include a touch sensing device (516), an AC-to-DC converter (512) operably connected to a receiver coil (510), a first capacitor (C S1 ) connected between the receiver coil (510) and one output terminal of the AC-to-DC converter (512), and a second capacitor (C S2 ) connected between the receiver coil (510) and another output terminal of the AC-to-DC converter (512). One or more capacitive shields can be positioned between the receiver coil (510) and an interface surface (212) of the receiver device (204).
