Abstract
Tiled display device (19) comprising an array of display units (18) which are mechanically and electrically coupled to each other by removable data and power connectors (50). The application also discloses a self-powered or partially self-powered display device (1) comprising a display layer (2) and a photovoltaic layer (3) behind the display layer. The display device may also include a light collecting lens system (7) for distributing light to the photovoltaic layer.
Claims21
A display array comprising first and second display units connected together at adjacent edges thereof, where each said adjacent edge has a combined power and data port, the combined power and data ports being mechanically connected together by a removable power and data connector that also provides power and data connections between the display units.
The array of 10, wherein one or more of the at least one additional combined power and data port that is not connected to another display unit is connected to a data connector for providing data to the array.
19-66. (canceled)
A first display unit, comprising:
- a first display screen having a photovoltaic layer;
- a first port, the first port disposed on a rear surface of the first display unit near a first edge of the first display unit, the first port configured to convey both power and data and to be connected to a first connector, the first connector configured to be connected to a second display unit so that the first display unit and the second display unit form a continuous display;
- a second port, the second port disposed on the rear surface near a second edge of the first display unit, the second edge orthogonal to the first edge, the second port configured to convey both the power and the data and to be connected to a second connector, the second connector configured to be connected to a third display unit so that the first display unit and the third display unit form the continuous display;
- and
- a rechargeable power cell configured to receive the power from the photovoltaic layer and to provide the power to at least the first display unit.
A connector, comprising:
- a first set of connectors disposed on a surface, the first set of connectors having a first power connector and a first data connector, the first set of connectors being configured to be connected to a first port of a first display unit;
- and
- a second set of connectors disposed on the surface, the second set of connectors having a second power connector and a second data connector, the second set of connectors being configured to be connected to a second port of a second display unit,
- wherein the connector is configured to convey both power and data between the first display unit and the second display unit.
