Method of making an electronic display
View Patent ↗A display formed by skiving with a skiving device including at least one nozzle tip and at least one roller is described. The display has skives that are clean and neat, and has no damage to layers underlying the skived areas.
1. A display comprising a substrate, wherein the substrate comprises a light modulating material, wherein the display is formed by:
providing the substrate, wherein the substrate comprises a light modulating material, to a skiving device comprising at least one roller having a surface and at least one nozzle tip;
contacting the surface of at least one roller and at least one nozzle tip with the light modulating material; and
moving the skiving device in relation to the substrate to skive at least a portion of the light modulating material in contact with at least one roller, at least one nozzle tip, or both.
2. The display of claim 1 , wherein at least one nozzle tip comprises a proximal end, a distal end, and a longitudinal axis extending from the proximal end to the distal end, the proximal end having an opening defined by a first edge and a second edge.
3. The display of claim 2 , wherein the first edge of the nozzle tip is at an angle of from 20 degrees to 90 degrees relative to the axis.
4. The display of claim 2 , wherein the second edge of the nozzle tip is at an angle of from 15 degrees to 70 degrees relative to the axis.
5. The display of claim 1 , wherein the light modulating material is chill-set, hardened, polymerized, or a combination thereof.
6. The display of claim 1 , wherein the light modulating material comprises liquid crystals, electrophoretic material, electrochromic material, bichromal materials, or a combination thereof.
7. The display of claim 1 , wherein the light modulating material comprises liquid crystals selected from cholesteric, nematic, ferroelectric, and smectic liquid crystals, or a combination thereof.
8. The display of claim 1 , wherein the substrate further comprises a conductive material below the light modulating material.
9. The display of claim 8 , wherein the conductive material is tin oxide or indium tin oxide.
10. The display of claim 8 , wherein the conductive material is transparent.
11. The display of claim 1 , wherein the skiving device further comprises a vacuum source.
