  • Publication number: 20190305062
    Abstract: A display may include flexible substrate, a blocking layer on the flexible substrate, a pixel on the flexible substrate and the blocking layer, and a scan line, a data line, a driving voltage line, and an initialization voltage line connected to the pixel. The pixel may include an organic light emitting diode, a switching transistor connected to the scan line, and a driving transistor to apply a current to the organic light emitting diode. The blocking layer is in an area that overlaps the switching transistor on a plane, and between the switching transistor and the flexible substrate, and receives a voltage through a contact hole that exposes the blocking layer.

  • Patent number: 5982759
    Abstract: A method for generating dummy frequencies to make frequency hard handover smooth in provision of a digital CDMA mobile communication service when base stations are different in frequency configuration. The coverage of each of the dummy frequencies becomes the same as that of a service frequency using basic signals of the service frequency. According to the present invention, a pilot channel signal, a sync channel signal, a paging channel signal and traffic channel signals of the service frequency are placed directly on each of the dummy frequencies. Therefore, the coverage of the dummy frequency can always become the same as that of the service frequency which is varied according to a traffic amount of the base station, so that a mobile station can perfectly perform the frequency hard handover. Further, one power combiner, one power amplifier and one power divider are provided to process all of the dummy frequencies.
