Abstract
An active-matrix device is provided which includes a plurality of array element circuits arranged in rows and columns; a plurality of source addressing lines each shared between the array element circuits in corresponding same columns; a plurality of gate addressing lines each shared between the array element circuits in corresponding same rows; a plurality of sensor row select lines each shared between the array element circuits in corresponding same rows, wherein each of the plurality of array element circuits includes: an array element which is controlled by application of a drive voltage by a drive element; writing circuitry for writing the drive voltage to the drive element, the writing circuitry being coupled to a corresponding source addressing line and gate addressing line among the plurality of source addressing lines and gate addressing lines; and sense circuitry for sensing an impedance presented at the drive element, the sense circuitry being coupled to a corresponding sensor row select line; and a row driver and a column driver.
