  • Patent number: 7754509
    Abstract: A manufacturing method for a thin film transistor (TFT) is provided. In the manufactured TFT, after a source structure, a drain structure and a channel structure are formed, a first photoresist layer is not removed and a second photoresist is formed on the first photoresist layer through which a semiconductor structure is formed. Further, n-type amorphous silicon, poly silicon or an organic metallic compound is used in replace of the conventional metal to form the source and drain structures so as to reduce step number of manufacturing for the TFT.

  • Patent number: 7432564
    Abstract: A method for fabricating a pixel structure is provided. First, a gate, a scan line, and a first terminal are formed on a substrate. A gate insulating layer is formed over the substrate to cover the gate, the scan line, and the first terminal. After defining the semiconductor layer, the gate insulating layer is patterned to exposure the first terminal. A transparent conductive layer is formed over the substrate and a patterned photoresist layer is formed on the transparent conductive layer. The transparent conductive layer is patterned using the patterned photoresist layer as a mask, so as to define a source, a drain, a data line, a pixel electrode, a second terminal, and a contact pad. Because only four photomasks are used to implement the above method for fabricating the pixel structure, the cost of manufacturing can be reduced.

  • Publication number: 20080111959
    Abstract: The structure of a trans-reflective liquid crystal display panel includes stacks in longitudinally and two areas in transversely, which are reflective area and transmissive area. A thin-film-transistor layer and a dielectric layer are formed on a substrate in sequential. For the transmissive area, a transparent conductive film, such as a pixel electrode, is formed. For the reflective area, a reflective film with multi-layer is formed on the dielectric layer and then the thin-film-transistor layer. After assembling, the trans-reflective liquid crystal display is complete. The materials of the reflective film with multi-layer and the dielectric layer are similar to have greater adhesion. Each layer of the reflective film with multi-layer includes two sublayers, the first reflective sublayer and the second reflective sublayer, which have the different refractive indexes. By modifying the temperature, pressure, gas flow and power of emitting in manufacturing process can make the refractive indexes of both layers.

The audio control system includes an audio controller, a first audio encoder/decoder and a second audio encoder/decoder. The audio controller has a first reset signal and a second reset signal. The first audio encoder/decoder is coupled to the audio controller and receives the first reset signal. The second audio encoder/decoder is coupled to the audio controller and receives the second reset signal. The hot plug-and-play mechanism can be achieved when the audio controller selectively enables the first reset signal or the second reset signal.
