Patents by Inventor Te-Chang Wan

Te-Chang Wan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8796691
    Abstract: A system for displaying images and fabricating method thereof are provided. The system includes a thin film transistor substrate including a substrate having a display area and a pad area. The thin film transistor substrate further includes a conductive line disposed on the substrate in the display area. The conductive line includes a lower metal line, an upper metal line and a middle metal line therebetween. The width of the middle metal line is narrower than that of the upper metal line.

  • Patent number: 8227808
    Abstract: An organic light emitting diode (OLED) display and thin film transistor (TFT) manufacturing method thereof are disclosed. According to the present invention, poly-silicon layers for forming active areas of non-driving TFT (e.g. peripheral circuit TFT and switch TFT) and driving TFT used in the OLED display are respectively made by using standard laser crystallization method and non-laser crystallization method or low energy laser crystallization method. Therefore, the peripheral circuit TFT has excellent electrical performance such as high carrier mobility, while the OLED-driving TFT has good stability so that the resultant display can operate with improved luminance uniformity.

  • Patent number: 8183064
    Abstract: A system for displaying images. The system includes a thin film transistor (TFT) device including a first gate layer disposed on a first region of a substrate and covered by a first insulating layer. A first polysilicon active layer is disposed on the first insulating layer and a second polysilicon layer is disposed on a second region of the substrate. A second insulating layer covers both of the first and second polysilicon gate layers. Second and third gate layers are respectively disposed on the second insulating layer above the first and second polysilicon active layers. A method for fabricating a system for displaying images including the TFT device is also disclosed.

  • Patent number: 8158985
    Abstract: A system for displaying images. The system includes a thin film transistor (TFT) device including a first insulating layer covering a first region and a second region of a substrate. A first polysilicon active layer is disposed in the first region and between the substrate and the first insulating layer. A second polysilicon active layer is disposed on the first insulating layer in the second region. A polysilicon gate layer is disposed above the first polysilicon active layer. A second insulating layer covers the polysilicon gate layer and the second polysilicon active layer. A metal gate layer is disposed above the second polysilicon active layer. A method for fabricating the system for displaying images including the TFT device is also disclosed.
