  • Publication number: 20230285609
    Abstract: A self-sterilizing display device is applied to self-sterilizing with a UV light. The self-sterilizing display device includes a display, a light-incident layer, a light source, and a transparent protective layer. The light-incident layer is disposed above the display. The light source is disposed at a periphery of the light-incident layer, and a light-emitting surface of the light source faces to the light-incident layer. The transparent protective layer is disposed between the light-incident layer and the display. Herein, the light source can emit the UV light toward the light-incident layer for sterilizing an outer surface of the self-sterilizing display device by irradiation, and the transparent protective layer can filter out the UV light. Therefore, the surface can be sterilized by UV light, and the UV light can be prevented or reduced from being incident on the display below and damaging the display.

  • Patent number: 9509296
    Abstract: Systems and methods herein may include or involve control circuitry that detects missing edges of reference and/or feedback clocks and may block the next N rising edges of the feedback clock or reference clock, respectively. In some implementations, a phase frequency detector (PFD) circuit comprises first circuitry including an output that outputs a missing edge signal. The first circuitry may include components arranged to detect a missing rising edge of one or both of a reference clock signal and a feedback clock signal. Second circuitry is coupled to the first circuitry and may include components arranged to generate one or both of a reference clock blocking signal and a feedback clock blocking signal based on the missing edge signal. Further, in some implementations, the blocking of the next N rising edges of the opposite clock may effectively increase the positive gain of the PFD.
