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 to write information on a display of a substrate, the substrate including:
a first longitudinal side, and a second longitudinal side opposite to the first longitudinal side, the display being between the first and second longitudinal sides,
the system comprising:
a first slot for receiving the first longitudinal side of the substrate and
a second slot for receiving the second longitudinal side of the substrate,
the first slot and the second slot being actuable so as to respectively constrain the first and the second longitudinal substrate sides.

2 . The system of claim 1 , further comprising a transparent volume formed between the first and the second slot so that the display is externally viewable while the first and the second longitudinal substrate sides are constrained at the first and second slot.

3 . The system of claim 2 , further including an imager to operate the display in an area opposite to the transparent volume while the first and the second longitudinal substrate sides are constrained by the 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 passing in relation to said writing device.

5 . The system of claim 3 , wherein the first and second slot are provided in a moveable tray, in an open position of the tray the substrate can be inserted in or extracted from the first and second slots, in a closed position of the tray the card can be operated by the imager.

6 . The system of claim 1 , wherein the constrainment is implemented by effecting a reduced slot width.

7 . The system of claim 3 , further comprising a substrate path via which the substrate is conveyed
from an insertion position where the substrate can be inserted 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 operated via the imager; and to an extraction position from which the substrate can be extracted from the system.

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

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

10 . A system to write information on a card, the card including:
a first longitudinal side, a second longitudinal side opposite to the first longitudinal side, and a display including electronic paper to display information,
the system comprising:
a first slot for receiving the first longitudinal side of the substrate;
a second slot for receiving the second longitudinal side of the substrate, wherein the first slot and the second slot are actuable to constrain the first and the second longitudinal sides therebetween; and,
a transparent window through which the display is externally viewable when the card is constrained at the first and second slot.

11 . The system of claim 9 , further comprising a charge source to produce a charge beam to write on the electronic paper, the charge source to be operated opposite to the transparent window 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:
constraining a first longitudinal side of the substrate via a first actuable slot; constraining a second longitudinal side of the substrate, opposite to the first longitudinal side, via a second actuable slot, whereby the substrate is constrained between the first and second slot with the display positioned therebetween; and operating the display to write information thereon via an imager while the substrate is constrained between the first and second slot.

13 . The method of claim 12 , wherein a transparent window is provided opposite the imager so that the display is externally viewable during the dynamic operation of the display.

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

15 . The method of claim 12 , wherein the substrate is a pocket-sized card and the display includes passive electronic paper that is operable by the imager, the imager being an external element from the substrate.
