  • Publication number: 20050237313
    Abstract: In order to detect pressure of a light source device against a display screen of a display device, the light source device changes an area of a light receiving region on the display screen in response to a degree of pressure of a tip of the light source device against the display screen. Meanwhile, a signal processing unit of the display device calculates a distance between a light transmission unit of the light source device and the display screen. By using this distance, the degree of pressure of can be detected. Moreover, in order to prevent malfunction attributable to outside environment light and to reduce power consumption of a light source unit of the light source device, the light source unit is configured not to output light when the tip of the light source device is not pressed against the display screen.

  • Patent number: 6952022
    Abstract: The present invention relates to an image sensor comprising an amorphous silicon thin-film transistor optical sensor which functions as an image sensor used for an X-ray photography device, a fingerprint recognition apparatus, a scanner, etc., and a method of manufacturing the image sensor. Since the thin-film transistor optical sensor according to the present invention has a high-resistance silicon region by disposing an offset region in a channel region, a dark leakage current of the optical sensor remains in a low level even under a high voltage. Therefore, it is possible to apply a high voltage to the thin-film transistor optical sensor according to the present invention so that the image senor can be sensitive to a weak light. In addition, since the storage capacitance in the image sensor is formed in a double structure, the image sensor has a high value of capacitance.
