Abstract

An exemplary driving member and an exemplary array module formed by a plurality of the driving members are disclosed in the invention. The driving member includes a first suspending beam module, a second suspending beam module and a conductive suspending beam module. When a voltage is provided between the first suspending beam module and the second suspending beam module, or the first suspending beam module and the second suspending beam module are provided with two homopolar voltages, when the electric field force is larger than the deforming force threshold of the first suspending beam, the first suspending beam moves to contact with the conductive suspending beam module, so that the first suspending beam has a voltage same with the conductive suspending beam module. When the electric field force is smaller than the deforming force threshold of the first suspending beam, the first suspending beam module rebounds to an original state.
