1. An apparatus, comprising:
- a plurality of display elements arranged in an array; and
a control matrix coupled to the plurality of display elements to communicate data and drive voltages to the display elements,wherein the control matrix, for each display element, includes;
an actuation circuit coupling a voltage source to a respective display element and configured to apply an actuation voltage to an actuator of the respective display element throughout an actuation stroke of the actuator; and
wherein the control matrix is configured to initiate the actuation of the actuator after a pre-charging signal that initiated the application of the actuation voltage to the actuator has been deactivated.

Abstract
An apparatus includes a plurality of display elements arranged in an array and a control matrix coupled to the plurality of display elements to communicate data and drive voltages to the display elements. For each display element, the control matrix includes an actuation circuit coupling a voltage source to the display element. The control matrix is configured to apply an actuation voltage to an actuator of the display element throughout an actuation stroke of the actuator and to initiate the actuation of the actuator after a pre-charging signal that initiated the application of the actuation voltage to the actuator has been deactivated.

23. An apparatus, comprising:
-
a plurality of display elements arranged in an array; and a control matrix coupled to the plurality of display elements to communicate data and drive voltages to the display elements, wherein the control matrix, for each display element, includes; a first actuation circuit coupling a voltage source to a respective display element and configured to apply an actuation voltage to a first actuator of the respective display element throughout an actuation stroke of the first actuator; a second actuation circuit coupling the voltage source to the display element and configured to apply the actuation voltage to a second actuator of the display element throughout an actuation stroke of the second actuator; and wherein the control matrix is configured to initiate the actuation of one of the first actuator and the second actuator after a pre-charging signal that initiated the application of the actuation voltage to the first actuator and the second actuator has been deactivated. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)
