Abstract
A display device includes a base structure, a plurality of modules coupled to the base structure, where each of the modules include a plurality of actuator assemblies. Each of the actuator assemblies is individually controllable to move the actuator assemblies between a retracted state and a plurality of extended states. A controller is coupled to each of the modules and is programmed to control the actuator assemblies to move the actuator assemblies between the retracted state and the plurality of extended states.
