5. The electronic device of claim 1 , wherein the one or more electromagnetic band gap structures comprises a narrowband electromagnetic band gap configured to mitigate or stop a surface current flow on the display for a narrowband frequency.

6. The electronic device of claim 1 , wherein the one or more electromagnetic band gap structures comprises a broadband electromagnetic band gap configured to mitigate or stop a surface current flow on the display for broadband frequencies.

7. The electronic device of claim 1 , wherein the one or more electromagnetic band gap structures comprises a narrowband electromagnetic band gap, the narrowband electromagnetic band gap comprising a straight line shape.

8. A display, comprising:

a display substrate;

a mid-support plate disposed adjacent to the display substrate, the mid-support plate including one or more electromagnetic band gap structures formed through and arranged in one or more rows across the mid-support plate to create a barrier across the mid-support plate, or one or more electromagnetic band gap structures disposed onto and arranged in one or more rows across the mid-support plate to create a barrier across the mid-support plate, or a combination thereof, the one or more electromagnetic band gap structures comprising one or more slots or one or more dielectric materials; and

a lower support plate disposed adjacent to the mid-support plate, wherein a gap exists between the mid-support plate and the lower support plate.

9. The display of claim 8 , wherein the mid-support plate and the lower support plate are conductive plates.

10. The display of claim 8 , wherein the one or more electromagnetic band gap structures comprises a plurality of electromagnetic band gap structures formed through the mid-support plate, the plurality of electromagnetic band gap structures not sharing a common edge.

11. The display of claim 10 , wherein the barrier is disposed across at least 85% of a width of the mid-support plate.

12. The display of claim 10 , wherein the barrier comprises at least two rows across the mid-support plate of the one or more electromagnetic band gap structures formed through the mid-support plate, the at least two rows disposed offset from each other.

13. The display of claim 10 , wherein the barrier comprises at least one row across the mid-support plate of the one or more electromagnetic band gap structures disposed onto the mid-support plate.

14. The display of claim 10 , wherein the barrier is configured to decrease a surface current from flowing across the display.

15. A support structure of a display, comprising:

a first support plate having a first surface and a second surface, the first surface disposed adjacent to a display layer comprising light emitting diodes (LEDs), the first support plate having a first edge and a second edge, the first edge opposite the second edge, wherein one or more slots are formed through the first support plate, the one or more slots configured to redirect a surface current flow from the first edge away from the second edge or from the second edge away from the first edge; and

a second support plate configured to be disposed adjacent to the second surface of the first support plate, wherein a space exists between the second support plate and the second surface of the first support plate.

16. The support structure of claim 15 , wherein the one or more slots are configured to be disposed across the first support plate to create a barrier across the first support plate.

17. The support structure of claim 16 , wherein the barrier across the first support plate is based on design features of the display, components on the second support plate, or a combination thereof.

18. The support structure of claim 15 , wherein the one or more slots tune for noise occurring on broadband frequencies, the one or more slots comprising a curved or bent shape.

19. The support structure of claim 15 , wherein the one or more slots comprises a width corresponding to a particular range of frequencies.

20. The support structure of claim 19 , wherein the width comprises between 1 millimeter and 3 millimeters.
