An electrowetting display device comprises electrowetting pixels. Each of the electrowetting pixels includes a hydrophobic layer portion disposed on a first electrode, an electrolyte solution overlying the hydrophobic layer, and a thin film transistor (TFT) that is switched on to select each of the electrowetting pixels using active matrix addressing, wherein the TFT is in electrical contact with the first electrode. The electrowetting display further includes a second electrode in electrical contact with the electrowetting pixels, and a reset control circuit in electrical contact with the second electrode to provide a reset pulse in unison to the electrowetting pixels.

This disclosure describes voice-enabled modular devices that act as functional, voice-controlled endpoints at which users may provide voice commands. The voice-enabled modular devices may include a power unit which may be installed into a wall permanently to serve as a power source, and a front-panel module which detachably couples to the power unit via a hardware interface. The hardware interface may allow the front-panel module and power unit to communicate with each other, and may further allow the power unit to provide power to the front-panel module. The power unit of the voice-enabled modular device described herein may be configured to provide power to multiple front-panel modules having different capabilities, and potentially different power requirements, thereby supporting multiple front-panel modules to increase the functionality of the voice-enabled modular devices.

Voice-enabled modular devices

Described herein are electronic devices that includes a display stack having a cover component atop a lightguide component and a display component below the lightguide component. In some instances, the cover component including an antiglare etching applied to a top surface of a coverglass and a touch pattern applied to a bottom surface of the coverglass. In some cases, an optically clear adhesive layer formed from two types of optically clear adhesive may be located between the cover component and the lightguide component and a ring adhesive may be applied to around an outer edge of the cover component, the optically clear adhesive and the lightguide component.
