IPC: H01L27/146
Filed: 1992-12-24
Abstract: PURPOSE: To improve the picture quality of a contact video sensor by removing crossover parts between data lines and between a data line and another metal line. CONSTITUTION: Respective terminals of a driving circuit are connected to common lines (CL1 to CLn ) which are connected to gates of switching elements of unit cells and anodes of photoelectric converting elements of the previous unit cells. All of the respective driving circuit terminals (G1 /VPD.n to Gn /VPDn-1 ) generate reverse bias voltages. Unit cells of respective blocks accumulate photocharges corresponding to received light. Thus, by removing a crossover part between data lines and a crossover part between a data line and another metal line which are hardly removed by a matrix circuit wiring system, noise generation due to parasitic capacitance generated in such crossover parts can be removed to obtain the contact video sensor with high picture quality.
