Display element
View Patent ↗In one embodiment, a display element includes a first electrode, a second electrode, and a dielectric layer on the second electrode. The dielectric layer has recess regions therein. The display element includes an opaque layer on the second electrode within each recess region and a fluid with colorant particles between the first electrode and the second electrode.
1. A display element comprising:
a first electrode;
a second electrode;
a dielectric layer on the second electrode, the dielectric layer having recess regions therein;
an opaque layer on the second electrode within each recess region; and
a fluid with colorant particles between the first electrode and the second electrode.
2. The display element of claim 1 , wherein the first electrode and the second electrode comprise a transparent conductor.
3. The display element of claim 1 , wherein the opaque layer is black.
4. The display element of claim 1 , wherein the opaque layer comprises a metal.
5. The display element of claim 1 , wherein the opaque layer comprises anodized portions of the second electrode.
6. The display element of claim 1 , wherein the opaque layer comprises a dielectric material.
7. The display element of claim 1 , wherein the recess regions comprise one of circular shaped regions and trench regions.
8. A display comprising:
a first display element comprising:
a transparent first electrode;
a transparent second electrode;
a transparent dielectric layer on the second electrode, the dielectric layer having recess regions therein;
a self-aligned opaque layer on the second electrode within each recess region; and
a fluid with colorant particles having a first color between the first electrode and the second electrode.
9. The display of claim 8 , further comprising:
a second display element stacked on the first display element, the second display element comprising:
a transparent first electrode;
a transparent second electrode;
a transparent dielectric layer on the second electrode, the dielectric layer having recess regions therein;
a self-aligned opaque layer on the second electrode within each recess region; and
a fluid with colorant particles having a second color between the first electrode and the second electrode.
10. The display of claim 9 , wherein the recess regions of the first display element are offset from the recess regions of the second display element.
11. The display of claim 9 , wherein the recess regions of the first display element are aligned with the recess regions of the second display element.
12. The display of claim 9 , further comprising:
a third display element stacked on the second display element, the third display element comprising:
a transparent first electrode;
a transparent second electrode;
a transparent dielectric layer on the second electrode, the dielectric layer having recess regions therein;
a self-aligned opaque layer on the second electrode within each recess region; and
a fluid with colorant particles having a third color between the first electrode and the second electrode.
13. The display of claim 12 , wherein the first display element, the second display element, and the third display element provide a full color display.
