  • Self-luminous reflective pixel structure, display panel, and display device
    Patent number: 9323114
    Abstract: A self-luminous reflective pixel structure, a display panel and a display device. The pixel structure includes a first electrode capable of reflecting light, a self-luminous layer disposed over the first electrode, a second electrode disposed over the self-luminous layer, and a reflected light control layer disposed over the second electrode. A self-luminous structure and a reflective structure can be formed in a single pixel with the pixel structure.
    Type: Grant

  • Transformerless photovoltaic grid-connecting inverting device and control method thereof
    Patent number: 8125807
    Abstract: The present invention relates to a transformerless photovoltaic grid-connecting inverting device and an inverting control method thereof. The inverting device comprising a boosting unit, an inverting unit, a grid-connecting unit and a control unit. The boosting unit is connected to a solar cell, for boosting an output voltage of the solar cell and then outputting a direct voltage. The inverting unit is used to convert the direct voltage output by the boosting unit into an alternating voltage. The grid-connecting unit is connected between the inverting unit and an alternating power grid, and closes or breaks up the electrical connection between the inverting unit and the alternating power grid based on a control signal.
