Apparatus and methods for resealing resized electronic displays
View Patent ↗Pre-manufactured electronic displays and, in particular, liquid crystal flat-panel displays, may be cut to a new size and resealed while preserving their originally-manufactured properties. A display may be cut, and the exposed edge of a target portion may be sealed, e.g., to preserve the integrity of the target portion of the display. It may be desirable to cause a sealant to go in between the plates of the panel, e.g., to achieve improved yield, chemical isolation, dimensional integrity, and/or strength of the seal. Apparatus and methods are disclosed where the sealant is injected or otherwise forced into the region between the plates adjacent the exposed edge. This sealing process may achieve more sealant surface contact area inside the panel in between the plates, e.g., to achieve better bonding strength, chemical isolation, and/or improved yield.
1. A method for changing the physical size and/or shape of an electronic display, wherein the display comprises a front plate, a back plate, and a perimeter seal, and wherein an image-generating medium is sealed in a region between the plates, and wherein electronic circuits are distributed throughout an original image area of the display, the method comprising:
cutting the display along desired dimensions resulting in a target display portion and an excess display portion thereby breaking the perimeter seal of the display and creating an exposed edge;
applying sealant along the exposed edge; and
rolling a roller along the exposed edge to force sealant into the region between the plates adjacent the exposed edge.
2. The method of claim 1 , further comprising:
applying additional sealant along the exposed edge after rolling the roller along the exposed edge; and
rolling the roller along the exposed edge to force additional sealant into the region between the plates adjacent the exposed edge.
3. The method of claim 1 , further comprising curing the sealant to create a first seal creating a barrier to prevent the image-generating medium from escaping out of the area between the plates.
4. The method as in claim 1 , wherein applying the sealant comprises placing a bead of sealant along the exposed edge.
5. The method of claim 4 , wherein the bead of sealant partially penetrates into the region between the plates adjacent the exposed edge before the roller is applied.
6. The method as in claim 1 , wherein the target display portion is held in a fixture to accommodate the application of the sealant.
7. The method as in claim 6 , where the fixture is a pressure plate configured to manipulate the target display portion to move the image-generating medium and promote the placement of the sealant between the plates.
8. The method of claim 1 , wherein a portion of the sealant is forced into the region between the plates adjacent the exposed edge, and another portion of the sealant is pressed against the exposed edge of the plates.
9. The method of claim 1 , wherein a trace material is provided in the sealant, and wherein the trace material is monitored after rolling the roller along the exposed edge to identify a depth of penetration of the sealant between the plates.
10. A method for changing the physical size and/or shape of an electronic display, wherein the display comprises a front plate, a back plate, and a perimeter seal, and wherein an image-generating medium is sealed in a region between the plates, and wherein electronic circuits are distributed throughout an original image area of the display, the method comprising:
cutting the display along desired dimensions resulting in a target display portion and an excess display portion thereby breaking the perimeter seal of the display and creating an exposed edge;
applying sealant along the exposed edge such that the sealant penetrates into the region between the plates adjacent the exposed edge; and
monitoring trace material within the sealant to identify a depth of penetration of the sealant between the plates.
11. The method of claim 10 , wherein the sealant is injected into the region between the plates adjacent the exposed edge.
12. The method of claim 11 , wherein monitoring trace material comprises:
determining that the depth of penetration is less than a desired depth of penetration; and
applying additional sealant between the plates along the exposed edge to increase the depth of penetration of the sealant.
13. The method of claim 10 , wherein the trace material comprises phosphorescent or fluorescent material and wherein monitoring the trace material comprises placing a light source adjacent the exposed edge to illuminate the trace material such that the phosphorescent or fluorescent material is visible to the naked eye.
14. The method of claim 10 , wherein applying sealant comprises:
applying a bead of sealant along the exposed edge; and
rolling a roller along the exposed edge to force sealant into the region between the plates adjacent the exposed edge.
15. The method of claim 10 , wherein monitoring trace material comprises:
determining that the depth of penetration is less than a desired depth of penetration, the method further comprising:
applying additional sealant along the exposed edge;
rolling the roller along the exposed edge to force additional sealant into the region between the plates adjacent the exposed edge; and
monitoring the trace material within the sealant to identify the additional depth of penetration of the sealant between the plates.
16. A method for changing the physical size and/or shape of an electronic display, wherein the display comprises a front plate, a back plate, and a perimeter seal, and wherein an image-generating medium is sealed in a region between the plates, and wherein electronic circuits are distributed throughout an original image area of the display, the method comprising:
cutting the display along desired dimensions resulting in a target display portion and an excess display portion thereby breaking the perimeter seal of the display and creating an exposed edge;
applying sealant along the exposed edge such that the sealant penetrates into the region between the plates adjacent the exposed edge; and
rolling a roller along the exposed edge to force sealant further into the region between the plates adjacent the exposed edge.
17. The method of claim 16 , further comprising:
applying additional sealant along the exposed edge after rolling the roller along the exposed edge; and
rolling the roller along the exposed edge to force additional sealant into the region between the plates adjacent the exposed edge.
18. The method as in claim 16 , wherein applying the sealant comprises placing a bead of sealant along the exposed edge.
