  • Patent number: 10739626
    Abstract: Provided are devices and methods capable of electronically controlling and varying aperture diameters or diffracting light. The method provides a solid-state device made up of a transparent bottom electrode (TBE), a layer of liquid crystal (LC) material overlying the TBE, and a field of selectively engageable transparent top electrodes (TTEs). Light incident to the TTEs is accepted and a voltage differential between one or more selected TTEs and the TBE. As a result, an optically transparent region is created in the LC material interposed between the selected TTEs and the TBE. Depending on the arrangement of the TTEs and their size respective to the wavelength of the incident light, the light is either transmitted through an aperture or diffracted.

  • Patent number: 10685992
    Abstract: An object is to provide a pixel structure of a display device including a photosensor which prevents changes in an output of the photosensor and a decrease in imaging quality. The display device has a pixel layout structure in which a shielding wire is disposed between an FD and an imaging signal line (a PR line, a TX line, or an SE line) or between the FD and an image-display signal line in order to reduce or eliminate parasitic capacitance between the FD and a signal line for the purpose of suppressing changes in the potential of the FD. An imaging power supply line, image-display power supply line, a GND line, a common line, or the like whose potential is fixed, such as a common potential line, is used as a shielding wire.
