Electronic display devices and methods are described. In one embodiment, a display device comprises a housing with a display area to display content for a user. Memory within the housing holds data that is to be rendered into user-viewable content. A loop of material is provided within the housing and is configured to display user-viewable content for the user. An exposure station is provided internally of the loop of material and is configured to expose selected portions of the loop of material so that the loop of material can receive and retain toner thereon to provide the user-viewable content from the data that is held in the memory. In another embodiment, a display device comprises a toner shuttling system within the housing that is configured to shuttle toner between different locations within the housing from which the toner can be used and reused. The shuttling system, in one implementation, takes the form of multiple toner reclamation/development stations, each of which being configured to operate to either reclaim toner or develop toner. The stations are desirably configured so that when one station operates to reclaim toner, another station operates to develop toner. In one particular implementation, the stations comprise a pair of switchably-biasable, bi-modal reclamation/development stations where, in one mode, a station develops toner and, in the other mode, the station reclaims used toner. Reclamation of toner can advantageously take place through non-invasive techniques, e.g. electrostatic techniques. |
