ABSTRACT:
An amorphous silicon sensor array is comprised of a plurality of individually addressable sensor elements. A control circuit, including gate lines, data lines and a control lines, selects the elements for readout discharge. The number of gate lines, data lines and control lines are reduced from conventional sensor array selective discharge control systems. The array includes a plurality of clusters of associated sensor elements wherein each element in a cluster includes a switch for switching integrated charge between the associated sensor elements. One of the gate lines and a one of the data lines is associated with each one of the clusters. The control line is associated with each of the sensor elements in each cluster for selectively and independently addressing for discharge the sensor elements in the clusters of the array.
