  • Patent number: 7868702
    Abstract: The subject invention provides a photoreceiver/amplifier circuit comprising a differential circuit including a differential transistor pair and a bias circuit; an active load; a feedback resistor for converting a photocurrent generated from a photodiode into a voltage; a reference resistor; and a compensation circuit. The resistance of the feedback resistor is greater than the resistance of the reference resistor. The compensation circuit supplies a compensation current from a junction between the feedback resistor and a non-inverting input terminal of the differential amplifier circuit, so as to cancel the difference between a voltage between terminals of the feedback resistor and a voltage between terminals of the reference resistor. This reduces noise and improves offset voltage characteristics. The present invention provides a photoreceiver/amplifier circuit ensuring noise reduction and desirable offset voltage characteristics.

  • Patent number: 7868960
    Abstract: An active matrix substrate includes a plurality of transistors. A source electrode is connected with a data signal line, and a drain electrode is connected with a pixel electrode in each transistor. The source electrode is located on a semiconductor layer, and at least a portion of the drain electrode is overlapped with the gate electrode. A gate insulating film covering the gate electrode of each transistor has a thin section having a reduced film thickness, at a portion where the gate insulating film is overlapped with each gate electrode. An overlapping area of the thin section with the source electrode is smaller than an overlapping area of the thin section with the drain electrode. Thus, the active matrix substrate can prevent the generation of short-circuits between the signal lines (between the data signal line and a scanning signal line) in a TFT forming region, while guaranteeing TFT characteristics.

  • Patent number: 7868551
    Abstract: A fluorescent tube in which no luminance gradient in the longitudinal direction occurs even when a one-side high-voltage driving method is used, a method of driving the fluorescent tube, an illuminating device for display device, and a display device having the illuminating device are provided. The fluorescent tube for one-side high-voltage driving is arranged behind a display panel via optical sheets. An internal diameter of the fluorescent tube is arranged to become larger gradually toward an electrode part at a high-voltage driving side, which prevents the occurrence of the luminance gradient in the longitudinal direction when a one-side high-voltage driving method is used.

  • Patent number: 7868991
    Abstract: In a wiring figure pattern of a display panel, each wiring is separated into bands of optimal widths by slits of a constant width as a wiring figure pattern so that minimum light irradiation for curing a photocuring sealing material can be carried out without increasing the electric resistance of the wiring. The optimal width means a resistance such that light coming from both sides of the band cures the sealing material on the upper surface of the band without influencing the driving and display of liquid crystal. At a point where the width of wiring becomes two times or more of the optical width between the start point and end point of intersection of the wiring and the sealing material region, the wiring is divided by the slit. A first branch forms the band of the optimal width extending from the branch point to the end point, whereas the second branch extends to the end point and is spaced apart from the first branch by the width of the slit.
