Patent ID: 7586473

Claim:
An active matrix array device comprising: a plurality of charging conductors; a plurality of addressing conductors crossing the plurality of charging conductors; and a plurality of matrix array elements, each matrix array element comprising a first switch having a control terminal coupled to an associated addressing conductor and a first data terminal coupled to an associated charging conductor, each matrix array element further comprising: a first capacitive device coupled to a second data terminal of the first switch; a second capacitive device coupled to the first capacitive device via a second switch having a control terminal responsive to a first enable signal, the second capacitive device having a smaller capacitance than the first capacitive device; a third switch coupled between the first capacitive device and a potential source, the third switch having a control terminal coupled to the second capacitive device; and a fourth switch coupled between the first capacitive device and the potential source, the fourth switch having a control terminal being responsive to a second enable signal.
