Apparatus and methods for resizing electronic displays
View Patent ↗Apparatus and methods for resizing COTS AMLCDs or other electronic displays, as well as resized displays made using these apparatus and methods, are provided. The electronic display includes a front plate, a back plate, a perimeter seal spacing the front and back plates apart, and image-generating medium contained in an area between the front and back plates. A target portion of the display may be identified and separated from an excess portion of the display, e.g., by cutting and breaking the plates of the display, thereby creating an exposed edge along the target portion. The plates of the target portion are pressed towards one another, e.g., to stabilize or compress the target portion. An adhesive is applied to the exposed edge, and the pressure is released to draw the adhesive between the plates along the exposed edge.
1. A method for resizing an electronic display, the display comprising a front plate, a back plate, a perimeter seal spacing the front and back plates apart, and image -generating medium contained in an area between the front and back plates and within the borders of the perimeter seal, the front and back plates being spaced apart by a predetermined cell gap, the method comprising:
identifying a target portion and an excess portion of the display;
separating the target portion from the excess portion, thereby creating an exposed edge along the target portion extending from one side edge to another side edge of the display and communicating with the area between the plates of the target portion;
stabilizing the target portion after separation such that the front and back plates are separated by a distance not greater than the predetermined cell gap;
applying adhesive along the exposed edge; and
forcing the adhesive into the region between the plates along the exposed edge.
2. The method of claim 1 , wherein the target portion of the display is mounted within a fixture for maintaining the plates at the predetermined cell gap.
3. The method of claim 2 , wherein the fixture presses the plates of the target portion towards one another before the adhesive is applied along the exposed edge, and returns the plates of the target portion to the predetermined cell gap to force the adhesive into the region between the plates.
4. The method of claim 2 , wherein the fixture comprises a pair of pressure plates between which the target portion of the display is mounted.
5. The method of claim 4 , wherein at least one of the pressure plates comprises a bladder disposed between the respective one of the pressure plates and the target portion of the display, and wherein the plates of the target portion are pressed towards one another by expanding the blabber.
6. The method of claim 4 , wherein the plates of the target portion are returned to the predetermined cell gap by at least partially deflating the bladder.
7. The method of claim 4 , wherein the target portion of the display is mounted to a first plate of the pressure plates, and wherein a second plate of the pressure plates is mounted to the first plate at a predetermined spacing.
8. The method of claim 1 , further comprising curing the adhesive, thereby creating a first seal between the plates along the exposed edge, the first seal creating a barrier to prevent the image-generating medium from escaping out of the area between the plates of the target portion.
9. The method of claim 1 , wherein image-generating material is forced out from the area between the plates along the exposed edge by compressing the plates of the target portion towards one another, and wherein the plates of the target portion are at least partially released to force the adhesive between the plates.
10. The method of claim 9 , further comprising removing image-generating material that is forced out along the exposed edge.
11. The method of claim 10 , wherein the image-generating medium is removed before the adhesive is applied along the exposed edge.
12. The method of claim 1 , wherein the adhesive is forced into the region between the plates by pressing against the exposed edge after applying the adhesive.
13. The method of claim 12 , wherein the adhesive is forced into the region between the plates using a tool.
14. The method of claim 12 , wherein the plates are maintained in a vertical orientation when the adhesive is applied to the exposed edge.
15. The method of claim 1 , wherein forcing the adhesive into the region between the plates increases the distance between the plates.
16. The method of claim 1 , wherein forcing the adhesive into the region between the plates displaces at least a portion of the image-generating material between the plates.
17. The method of claim 1 , wherein forcing the adhesive into the region between the plates causes the adhesive to mix with image-generating material between the plates.
18. The method of claim 1 , wherein the adhesive is forced into the region between the plates using a dispenser.
19. The method of claim 18 , wherein the adhesive is applied from the dispenser substantially uniformly along the exposed edge.
20. A method for resizing an electronic display, the display comprising a front plate, a back plate, a perimeter seal spacing the front and back plates apart, and image -generating medium contained in an area between the front and back plates and within the borders of the perimeter seal, the front and back plates being spaced apart by a predetermined cell gap, the method comprising:
identifying a target portion and an excess portion of the display;
separating the target portion from the excess portion, thereby creating an exposed edge that extends from one side edge to another side edge of the display along the target portion communicating with the area between the plates of the target portion;
pressing the plates of the target portion towards one another; and
at least partially releasing the plates of the target portion to draw adhesive between the plates along the exposed edge.
21. A method for resizing an electronic display, the display comprising a front plate, a back plate, a perimeter seal spacing the front and back plates apart, and image -generating medium contained in an area between the front and back plates and within the borders of the perimeter seal, the front and back plates being spaced apart by a predetermined cell gap, the method comprising:
identifying a target portion and an excess portion of the display;
separating the target portion from the excess portion, thereby creating an exposed edge along the target portion communicating with the area between the plates of the target portion;
applying adhesive along the exposed edge; and
forcing the adhesive into the region between the plates along the exposed edge, thereby displacing at least a portion of the image-generating material between the plates.
22. The method of claim 21 , wherein the adhesive is forced into the region between the plates using a tool or dispenser.
23. The method of claim 21 , wherein forcing the adhesive into the region between the plates causes the adhesive to mix with image-generating material between the plates.
24. The method of claim 21 , wherein forcing the adhesive into the region between the plates increases the cell gap between the plates.
25. The method of claim 1 , wherein the exposed edge extends from one side edge of the display to an adjacent side edge of the display to remove a corner of the display.
26. The method of claim 1 , wherein the exposed edge extends from one side edge of the display to an opposite side edge of the display such that the excess portion is substantially rectangular.
27. The method of claim 1 , wherein the exposed edge extends from one side edge of the display to an opposite side edge of the display such that the target portion is substantially square.
28. The method of claim 20 , wherein the exposed edge extends from one side edge of the display to an adjacent side edge of the display to remove a corner of the display.
