  • Publication number: 20210225910
    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.

  • Patent number: 10996320
    Abstract: An appropriate light emission frequency is set in an electronic device that determines a phase difference between radiation light and reflected light. The electronic device includes a light emission unit, a determination unit, and a setting unit. The light emission unit radiates intermittent light in synchronization with a synchronization signal at a set frequency that is set. The light reception unit generates received light data by receiving reflected light of the intermittent light. The determination unit determines presence or absence of a predetermined object on the basis of the received light data. The setting unit sets, in the light emission unit, as the set frequency, a frequency that is higher, the smaller the distance to the predetermined object, in a case where presence of the predetermined object is determined.
