  • Publication number: 20190363138
    Abstract: An individual hole transport layer is individually disposed between a common hole transport layer and a light emitting layer in each sub pixel, and the energy level value of the lowest unoccupied molecular orbital of the individual hole transport layer is smaller than the energy level value of the lowest unoccupied molecular orbital of the common hole transport layer, but larger than the energy level value of the lowest unoccupied molecular orbital of the light emitting layer in sub pixel. Thus, a hole can be efficiently injected into the light emitting layer.

  • Patent number: 8729813
    Abstract: Implemented are a switching power supply device and a light-emitting diode lighting device in which a variation in load current can be suppressed against a wide range of variation in AC voltage. The configuration of the switching power supply device and the light-emitting diode lighting device includes: a rectifier unit which rectifies AC input voltage and outputs pulsating-current voltage; a power converting unit which receives the pulsating-current voltage and supplies a predetermined load current to a load; a current detecting unit which detects the load current; a drive control unit which controls the power converting unit to regulate the load current to a constant level; and an input voltage detecting unit which detects a variation in the AC input voltage. The drive control unit controls the power converting unit depending on the variation in the AC input voltage detected by the input voltage detecting unit.

  • Patent number: 7271734
    Abstract: A remote control transmitter is so constructed that when a group menu representing a combination of individual functions is selected by operation of an operating part, a controller effects display of the individual functions of the group menu in parallel with the group menu. Since the correspondence between an overview of the plurality of group menus and the individual functions of the specified group menu is easy to understand, the remote control transmitter obtained allows easy setting of the function.
