  • Patent number: 11968856
    Abstract: Exemplary subpixel structures include a directional light-emitting diode structure characterized by a full-width-half-maximum (FWHM) of emitted light having a divergence angle of less than or about 10°. The subpixel structure further includes a lens positioned a first distance from the light-emitting diode structure, where the lens is shaped to focus the emitted light from the light-emitting diode structure. The subpixel structure still further includes a patterned light absorption barrier positioned a second distance from the lens. The patterned light absorption barrier defines an opening in the barrier, and the focal point of the light focused by the lens is positioned within the opening. The subpixels structures may be incorporated into a pixel structure, and pixel structures may be incorporated into a display that is free of a polarizer layer.

  • Publication number: 20240043710
    Abstract: A conductive ink may include an ultraviolet-curable resin and high-aspect-ratio conductors, such as nanowires or carbon nanotubes, dispersed in the ultraviolet-curable resin. The conductive ink may be fully curable at room temperature in under a minute with a curing depth of at least 100 microns, without heat, moisture, or a secondary curing step. The conductive ink may also have pigment and/or dyes within the ultraviolet-curable resin, and the conductive ink may be opaque at infrared wavelengths and transparent at ultraviolet wavelengths. The conductive ink may ground the cover glass of an electronic device display to a metal structure within the electronic device, such as a metal plate of the display, to prevent an accumulation of charge at the cover glass.

  • Patent number: 10845925
    Abstract: An electronic device such as a device with a display may have a force sensor. The force sensor may include capacitive electrodes separated by a deformable layer such as a layer of an elastomeric polymer. The display or other layers in the electronic device may deform inwardly under applied force from a finger of a user or other external object. As the deformed layers contact the deformable layer, the deformable layer is compressed and the spacing between the capacitive electrodes of the force sensor decreases. This causes a measurable rise in the capacitance signal and therefore the force signal output of the force sensor. To prevent the deformable layer from sticking to the inner surface of the display layers, air flow promotion structures may be interposed between the deformable layer and the inner surface of the display. The air flow promotion structures may include spacer pads with anti-stick surfaces.

  • Patent number: 10760405
    Abstract: Disclosed is an apparatus and method for imaging semi-three-dimensional rock formation along the borehole sidewall, and a database, a calculation module, and a pattern generation module are included and can be configured in an electronic device. The database continuously fetches the acoustic reflection amplitude data from a high resolution acoustic televiewer (HiRAT), which moves vertically along the borehole. The calculation module performs a mathematical and statistical process on the acoustic reflection amplitude data for the pattern generation module to generate the image of semi-three-dimensional structure of rock formation along the borehole sidewall. Thus, the semi-3D rock formation image provided by the present invention is beneficial for the researcher to easily identify the characteristics of rock formation.
