A self-contained automatic access port unit having a sensor that recognizes when refuse is approaching the cover, and to activate a direct current motor, solenoid, or drive cylinder which in turn moves a drive arm to open a cover to permit refuse to drop through the access port unit into a trash container therebelow, thereby avoiding the need for a user to make contact with the trash access port. For example, the system can include at least one nanostructure extending along an axial direction between a proximal end and a distal end. The configuration of the display introduces a threshold level in the electric or magnetic field required to move the phoretic particle between defects within the cell. A tilt angle of the tilted surfaces offsets an optimal viewing angle for the display from a glare angle for the display. Methods of use are also provided.
