Patent ID: 8466858

Claim:
In an array of electrical devices formed in rows and columns, the array coupled to a plurality of row electrodes and a plurality of column electrodes, a method of determining an electrical characteristic of one or more selected electrical devices, each selected electrical device located in a selected row of the array and in a selected column of the array, the method comprising: determining a first value of the electrical characteristic between selected one or more row electrodes and said plurality of column electrodes, said plurality of column electrodes being driven to a common voltage and at least a portion of non-selected row electrodes being configured in a floating state for the first value; determining a second value of the electrical characteristic between the selected one or more column electrodes and said plurality of row electrodes, said plurality of row electrodes being driven to a common voltage and at least a portion of non-selected column electrodes being configured in a floating state for the second value; determining a third value of an electrical characteristic between the selected one or more row electrodes and the selected one or more column electrodes, the non-selected column and row electrodes being configured in a floating state for the determination of the third value; and determining a resulting electrical characteristic or operational state of the one or more selected electrical devices based at least in part on the first and second values, and the third value of the electrical characteristic.
