  • Patent number: 10175470
    Abstract: The disclosed examples relate to methods and systems facilitate self-healing of regions of electrowetting devices. Electrowetting devices may be coupled to a switchable AC/DC electrical power supply that provides AC power to the electrowetting device to control electrowetting device operation and DC power to promote self-healing of the electrowetting device. A monitoring circuit outputs a signal in response to electrical power supply operating characteristic changes due to a failure of the electrowetting device's dielectric. The controller, responding to the signal, switches the power supply output from AC power to DC power to the electrowetting device. In response to the DC power, the electrowetting device responds by healing the degraded dielectric. When the failure is determined to be corrected, the power supply output is switched from DC power to AC power to the electrowetting device. The number of times self-healing is applied may be tracked for future analysis.

  • Patent number: 10126544
    Abstract: A display panel includes a first substrate and a second substrate which are arranged opposed to each other. The space between the first substrate and the second substrate is separated into a plurality of sub-pixel regions. Within each sub pixel region, a first electrode, a first fluid layer, a second fluid layer, a hydrophobic dielectric layer and a second electrode are arranged in this order. The first fluid layer is made of hydrophilic liquid. The second fluid layer is made of ink. When no electric field is applied between the first electrode and the second electrode, the ink spreads over the surface of the hydrophobic dielectric layer. When an electric field is applied between the first electrode and the second electrode, the ink aggregates to expose the hydrophobic dielectric layer.

  • Patent number: 10120184
    Abstract: Subject matter disclosed herein relates to improving luminance and reducing color shifts in electrowetting displays. The electrowetting display comprises a plurality of electrowetting elements separated by partition walls and spacers. The spacers and/or partition walls are reflective. When incident light that enters a pixel or subpixel is reflected and encounters a spacer and/or partition wall, the light is reflected such that the reflected light exits the pixel or subpixel into which the incident light entered. This improves luminance and reduces color shifts of the electrowetting display.

The layered element also includes a central layer inserted between the outer layers. The central layer is formed either by one or more layers made of metallic material or made of dielectric material having a refractive index different from that of the outer layers. All of the contact surfaces between two adjacent layers of the layered element are textured and parallel to one another. A ratio of a total reflection of the layered element on a side of a first outer layer in a given wavelength range to a total reflection of the layered element on a side of a second outer layer in the given wavelength range is greater than or equal to 1.5.

  • Patent number: 10041837
    Abstract: The present invention relates to a radiation imaging sensor with at least one detection element, which is implemented on a substrate as a micromechanical resonator and which absorbs the radiation to be detected. The resonator is set into a resonant oscillation with an excitation device and a shift in the resonance frequency of the detection element under exposure to radiation is detected with a detection device. The radiation sensor is characterized by the fact that it comprises a scanning device with a single-axis or multi-axis tiltable scanning element. The facility to tilt the device means that the detection element can be used to detect radiation from different directions. The imaging sensor can be realized in a compact manner and be economically produced.
