Various embodiments are described herein for an ocular device implantable in a user's eye and which has an adjustable optical element for varying one or more optical properties for the eye such as, but not limited to, providing a dynamically adjustable aperture stop to control the amount of incoming light, filtering incoming light, polarizing incoming light, and/or varying a depth of field for the eye.

An optical device stack includes at least one of a photodetector or an optical emitter and a metasurface. The metasurface is disposed over a light-receiving surface of the photodetector or a light emission surface of the optical emitter. The metasurface includes a first conductive layer having an electrically-tunable optical property and an array of conductive nanostructures disposed on a first side of the first conductive layer. A second conductive layer is disposed on a second side of the first conductive layer. An electrical insulator is disposed between the first conductive layer and the second conductive layer. A change in an electrical bias between the metasurface and the second conductive layer, from a first electrical bias to a second electrical bias, tunes the electrically-tunable optical property from a first state to a second state, and changes an electrically-tunable optical filtering property of the metasurface.

The present disclosure relates to a touch dimming device including a touch panel and an active color changing film. The touch panel includes a first electrode and a second electrode to perform touch detection according to a coupling capacitance between the first electrode and the second electrode. The active color changing film includes a third electrode and a polymer layer. The polymer layer is configured to change a light transmittance of the active color changing film according to a voltage difference between the second electrode and the third electrode.

Devices, arrangements, and techniques are provided to improve the color saturation of displays such as OLED displays while avoiding or substantially reducing any increase in power consumption that typically would be associated with such increase in saturation. A three-subpixel per pixel red/green/blue (RGB) architecture is provided as well as a four sub-pixel approach which uses two red sub-pixels for each pixel (red/red/green/blue, or R1R2GB).
