  • Patent number: 8044905
    Abstract: A new TFT arrangement is demonstrated, which enables prevention of TFT to be formed over a joint portion between the adjacent SOI layers prepared by the process including the separation of a thin single crystal semiconductor layer from a semiconductor wafer. The TFT arrangement is characterized by the structure where a plurality of TFTs each belonging to different pixels is gathered and arranged close to an intersection portion of a scanning line and a signal line. This structure allows the distance between regions, which are provided with the plurality of TFTs, to be extremely large compared with the distance between adjacent TFTs in the conventional TFT arrangement in which all TFTs are arranged in at a regular interval. The formation of a TFT over the joint portion can be avoided by the present arrangement, which leads to the formation of a display device with a negligible amount of display defects.

    Abstract: The invention provides a laser light detection circuit that prevents a peak output occurring when the circuit switches between the operation stop mode and the operation mode so as to prevent the breakdown or malfunction of the next-connected circuit. A laser light detection circuit has a differential amplifier that amplifies and outputs a signal corresponding to the intensity of laser light, a drive transistor having a base to which the output of the differential amplifier is applied, a second constant-current source connected to the emitter of the drive transistor, an output transistor having a base connected to the emitter of the drive transistor, a bypass transistor connected between the emitter of the drive transistor and the ground, and a control circuit. The control circuit forms a bypass current route from the second constant-current source to the ground through the bypass transistor by turning on the bypass transistor when the circuit switches from the operation stop mode to the operation mode.
