  • Patent number: 7777231
    Abstract: A method for forming a thin film transistor on a substrate is disclosed. A gate electrode and a gate insulation layer are disposed on a surface of the substrate. A deposition process is performed by utilizing hydrogen diluted silane to form a silicon-contained thin film on the gate insulation layer first. A hydrogen plasma etching process is thereafter performed. The deposition process and the etching process are repeated for at least one time to form an interface layer. Finally, an amorphous silicon layer, n+ doped Si layers, a source electrode, and a drain electrode are formed on the interface layer.

    Abstract: A dual view display structure and a method for producing the same are provided. First, a display panel is provided. Then, a patterned barrier layer is formed on a transparent substrate. The transparent substrate with the patterned barrier layer is attached to the display panel. Because there is a gap between the display panel and the patterned barrier layer, a liquid transparent material is injected into the gap to form a transparent material layer to fill the gap. The invention can not only increase the viewing angles of the dual view display, but also increase the production yield.
