Abstract

The present disclosure describes writing information on substrate displays. In an example, a display on a substrate is interfaced. The interfacing includes constraining a first longitudinal side of the substrate via a first actuable slot. Further, a second longitudinal side of the substrate opposite to the first longitudinal side is constrained via a second actuable slot. Thereby the substrate is constrained between the first and second slot with the display positioned therebetween. Further, the display is operated to write information thereon via an imager while the substrate is constrained between the first and second slot.

First claim

What is claimed is:

1. A system comprising:
a first slot to receive a first longitudinal side of the substrate, the first slot including opposite spaced apart first slot members actuable into contact against opposite faces of the substrate to constrain the first longitudinal side;
a second slot to receive the second longitudinal side of the substrate, the second slot including opposite spaced apart second slot members actuable into contact against opposite faces of the substrate to constrain the second longitudinal side,
the first slot and the second slot being actuable to respectively constrain the first and the second longitudinal sides to write information on a display of the substrate.

2. The system of claim 1 , comprising
a transparent volume defined between the first and the second slot to arrange the display to be externally viewable on a first face of the substrate through the transparent volume by a user while the first and the second longitudinal sides of the substrate are constrained at the respective first and second slots.

3. The system of claim 2 , comprising:
an imager positioned, in an area adjacent an opposite second face of the substrate, opposite to the transparent volume to operate the display, including writing information, while the first and the second longitudinal sides are constrained by the respective first and second slots.

4. The system of claim 3 , wherein the display includes electronic paper and the imager includes a writing device to operate the electronic paper, including writing information, passing in relation to the writing device.

5. The system of claim 3 , wherein the first and second slot are provided in a moveable tray, wherein in an open position of the tray the substrate is insertable or extractable from the first and second slots, and wherein in a closed position of the tray the substrate is operable by the imager.

6. The system of claim 3 , further comprising a substrate path via which the substrate is conveyed:
from an insertion position in which the substrate is insertable in the system;
further to a central position in which the substrate is constrained via the first and the second slots and the display is operable via the imager; and
to an extraction position from which the substrate is extractable from the system.

7. The system of claim 6 , comprising an automatic conveyor system to convey the substrate through the substrate path.

8. The system of claim 1 , wherein actuation of the first slot members into contact against opposite faces of the substrate is to cause a reduced slot width between the respective second slot members and wherein actuation of the second slot members into contact against opposite faces of the substrate is to cause a reduced slot width between the respective second slot members.

9. The system of claim 1 , wherein at least one of the first slot or the second slot is continuous.

10. The system of claim 9 , comprising:
a charge source to produce a charge beam to write on the electronic paper, the charge source positionable adjacent an opposite second face of the card to be operated opposite to the transparent window when the card is constrained at the first and second slot.

11. A system to write information on a card, the system comprising:
a first slot to receive a first longitudinal side of the card, the first slot including opposite first slot members actuable into contact against opposite faces of the card to constrain the first longitudinal side;
a second slot to receive a second longitudinal side of the card, the second slot including opposite second slot members actuable into contact against opposite faces of the card to constrain the second longitudinal side; and
a transparent window positioned between the first slot and the second slot and through which a display, including electronic paper on which information is displayable, of the card is externally viewable on a first face of the card by a user when the card is constrained at the first and second slot.

12. A method to interface with a display on a substrate, the method comprising:
arranging the substrate with the display in a position between a first longitudinal side and a second longitudinal side of the substrate;
constraining the first longitudinal side of the substrate via first actuable slot members movable into contact against opposite faces of the substrate at the first longitudinal slide;
constraining the second longitudinal side of the substrate, opposite to the first longitudinal side, via second actuable slot members movable into contact against opposite faces of the substrate at the second longitudinal side; and
operating the display to write information, via an imager, on a second face of the substrate while the substrate is constrained between the first slot members at the first longitudinal side and between the second slot members at the second longitudinal side.

13. The method of claim 12 , comprising:
arranging transparent window to extend from the first slot members to the second slot members and to be opposite the imager so that a first face of the substrate, including the display, is externally viewable through the transparent window by a user during the dynamic operation of the display.

14. The method of claim 12 , comprising:
arranging the display of the substrate to include electronic paper and arranging the imager to include an ion head, wherein the writing includes producing an ion beam via the ion head to write on the electronic paper.

15. The method of claim 12 , comprising:
arranging the substrate as a pocket-sized card and arranging the display to include passive electronic paper that is operable by the imager, the imager being an external element from the substrate.
