摘要： A close-contact image sensing device has at least a plurality of blocks each including the combinations each consisting of a photo sensing element and a photo sensing element select switch connected in series to the photo sensing element, and a common signal line used, when an image signal is read in each block. A read signal flows through the common signal line. An amount of charge as is stored in an equivalent capacitor of the photo sensing element in accordance with an amount of light incident on the photo sensing element, is transferred to a capacitor connected to the common signal line by turning on the photo sensing element select switch. In the image sensing device, a reset switch is connected at one end to a node between the photo sensing element and the photo sensing element select switch, and at the other end to a ground point. A photo sensing element select signal, which is applied to the photo sensing element select switch in a block in which a read operation will be executed, is also applied as a reset signal to the reset switch in a block in which a read operation has been completed, whereby the charge as still left in the photo sensing element after the charge transfer is drained to the ground point.

摘要： An image sensor has blocks of light-receiving elements which are switched by respective associated thin-film transistors. Charges generated in the light-receiving elements are transferred to respective common signal lines through a matrix wiring on a block basis. Capacitor forming lines are formed above the common signal lines in a crossed relationship through an interposed insulating layer to provide a capacitance substantially equal to a source-gate overlap capacitance of each thin-film switching transistor. A voltage signal in an inverse phase relation to a gate control signal is applied to the capacitor forming lines to cancel out coupling of the gate control signal to the potential of the common signal lines.
