摘要： An active matrix array of electroactive polymer actuators (36) is provided, each electroactive polymer actuator (36) having a switching arrangement (34). The switching arrangement comprises an input which is connected to a respective data line (30) and an output which is connected to a first terminal of the associated electroactive polymer actuator (36), wherein a second terminal of each electroactive polymer actuator is connected to a control line (110). A driver provides drive signals which comprise at least first and second drive levels for application to the data lines and third and fourth drive levels for application to the control line. Use is made of of common electrode driving (i.e. the control line driving) to enable low transistor control voltages to be used to switch larger voltages across the electroactive polymer actuators.

摘要： An actuator device comprises an active matrix array of rows and columns of electroactive polymer actuators, each electroactive polymer actuator having a switching circuit. The switching circuit has a drive transistor and a capacitor arrangement. The capacitor arrangement is charged to a voltage derived from a drive voltage for the electroactive polymer actuator combined with a voltage derived from the drive transistor threshold voltage. During this programming of the capacitor arrangement, the EAP actuator is isolated from any current flowing. The switching circuit enables compensation for age- related changes in the threshold voltage. Thus, a low performance (i.e. with poor threshold voltage stability) transistor may be used, with measurement of the threshold voltage of the current-providing TFT once per frame time (or once per multiple frame times) to compensate for the aging effect.
