  • Patent number: 7932962
    Abstract: A liquid crystal display device includes a pixel electrode, a thin film transistor, a gate line electrically coupled to the pixel through the thin film transistor and a first auxiliary layer having a first connecting portion overlapped with the pixel electrode and a second connecting portion overlapped with the gate line. The pixel electrode is non-overlapped with the gate line and the first auxiliary layer is electrically insulated from the pixel electrode and the gate line. When a white defect occurs, the pixel electrode is electrically connected to the gate line through the first auxiliary layer thereby repairing the white defect as a black defect.

  • Patent number: 7772117
    Abstract: Methods of fabricating highly conductive regions in semiconductor substrates for radio frequency applications are used to fabricate two structures: (1) a first structure includes porous Si (silicon) regions extending throughout the thickness of an Si substrate that allows for the subsequent formation of metallized posts and metallized moats in the porous regions; and (2) a second structure includes staggered deep V-grooves or trenches etched into an Si substrate, or some other semiconductor substrate, from the front and/or the back of the substrate, wherein these V-grooves and trenches are filled or coated with metal to form the metallized moats.

  • Patent number: 7646276
    Abstract: The transformer has a bobbin, a coil assembly and a magnetic core assembly. The bobbin is mounted in the magnetic core assembly and has multiple connecting pins being formed on at least one side of a bottom surface of the bobbin. Each connecting pin has a top surface as a soldering surface that corresponds to a solder pad on a back of a circuit board. At least one fastener is further formed on the bottom surface of the circuit board. Therefore, when the transformer is mounted through the circuit board, the connecting pins are soldered on the back of the circuit board to reduce the total thickness of the combination of the transformer and the circuit board.

The optical output system comprises: a light emitting device, a driver and an auto power controller. The light emitting device is used for generating emitting light. The driver is used for driving the light emitting device. The auto power controller is used for outputting a control signal to the driver according to at least one input signals so as to control the power of the light emitting device at a predetermined range. According to the invention, the optical output system can output the stable power of the emitting light at a predetermined value within the predetermined range under various conduction and circumference by a feedback control. Furthermore, the optical mouse using the optical output system can work on various reflective surface.
