  • Patent number: 7785941
    Abstract: A method for fabricating a thin film transistor (TFT) is provided. A substrate having a gate, a dielectric layer, a channel layer and an ohmic contact layer formed thereon is provided. Next, a metal layer is formed over the substrate covering the ohmic contact layer. Next, the metal layer and the ohmic contact layer are simultaneously etched by a wet etching process to form a source/drain and expose the channel layer. Because the wet etching process can be used to selectively etch the ohmic contact layer, damage to the underlying channel layer may be negligible. Thus, the reliability of the device may be promoted. Furthermore, the process may be simplified, the production yield and the throughput of TFT may be increased.

  • Patent number: 7786973
    Abstract: A region-based image display device includes a backlight module, a separating unit, a signal-processing unit, and a modulation unit. The backlight module includes several backlight regions. Each backlight region includes an adjustable luminance unit. Each luminance unit has a basis luminance value. The separating unit separates an input image signal into several image region signals corresponding to the backlight regions. The signal-processing unit transforms the image region signals into several output image signals. The modulation unit adjusts the basis luminance values to output luminance values according to the image region signals. Each basis luminance value and the corresponding image region signal on the one hand, and the corresponding output luminance value and output image signal, on the other hand, cooperatively define substantially the same chromaticity and brightness.
