  • Patent number: 10739925
    Abstract: There are provided a display device and a method for fabricating the display device. The display device includes a thin-film transistor located in each pixel defined by intersection between a gate line extending in a first direction and a data line extending in a second direction on a substrate. A first electrode has a first layer connected to one of a source electrode or a drain electrode of the transistor through the first contact hole and a second layer located on the first layer and in the first contact hole. There is also a signal line including a first signal line layer formed on the first protective layer of the same material on the same layer as the first layer of the first electrode and a second signal line layer formed on the first signal line layer of the same material as the second.

  • Patent number: 8896375
    Abstract: Provided is a hybrid envelope amplifier having improved efficiency, and more particularly, to an envelope amplifier using a dual switching amplifier and having improved efficiency in which power consumption is reduced by controlling a switching current of a switching region according to a magnitude of an envelope input signal, thereby improving efficiency compared to a conventional hybrid envelope amplifier. The envelope amplifier using a dual switching amplifier and having improved efficiency comprises a linear amplifier and a switching amplifier, wherein the switching amplifier includes two or more switching stages that are selectively operated according to a magnitude of an input signal.
