Title: Shift register and display
Inventor: WADA ATSUSHI
IPC: G11C19/28
Filed: 1994-10-19
Abstract: PURPOSE:To obtain an active matrix system TFT-LCD provided with an on-chip driver performing inspection of defect and redundancy switching. CONSTITUTION:Each normal shift register RSR1-RSRm is subjected to defect inspection by means of an on-chip circuit (detector 14 and selection circuit 15). Data shift and parallel output of a shift register 5 are controlled according to the inspection results and redundancy switching is made automatically. In other words, when each transmission gate 11, 12 is turned ON/OFF and the normal shift register does not function normally, a serial output from a corresponding spare shift register is fed to the normal and spare shift registers in the next stage. When the normal shift register does not function normally, an output selector 13 selects a spare shift register corresponding to the normal shift register and a parallel output is delivered to an analog switch 4.

Title: Photoconductive film lamination type solid-state image sensing device
Inventor: YASAKA MAMORU
IPC: H01L27/146
Filed: 1990-09-27
Abstract: PURPOSE:To acquire a complete black reference signal by providing a charge drain part which is provided to a region in contact with a working picture element region inside a black reference picture element region, collects a signal charge formed in the working picture element region and drains it outside the black reference picture element region. CONSTITUTION:High luminance light 16 is injected to an effective picture element region 1 near a black reference picture element region 2. In the process, a large number of signal charges 42 are generated in a photoconductive film layer 7 due to the high luminance light 16. A part of the signal charge 42 is collected to a picture element electrode 8 by an electric field formed inside the photoconductive film layer 7. Since a signal charge amount which can be collected by the picture element electrode 8 is limited by a charge storage capacity of a picture element, an excessive signal charge 43 remains, and the excessive signal charge 43 proceeds in the photoconductive film layer 7 in a direction of the black reference picture element region 2. However, since a charge drain part 40 keeps a fixed voltage through a bonding pad part 41, the excessive signal charge 43 is thereby drained outside the solid state image sensing device through a bonding pad part 41.
