EMI filters control the amount of EM energy that flows through a display, directing it to the appropriate place, using a combination of capacitors and inductors. Using a filter over a shield can create a thinner and more lightweight display. Filters focus on the conducted noise while shields tend to focus on EMI emissions themselves. It is possible to use both a filter and a shield.
EMI shielding protects the entirety of the display in the form of a copper, aluminum, or stainless steel plate. This not only protects the display unit from EMI but limits the amount of interference that it produces itself. EMI shields also have the ability to absorb some of the EM wave and convert it into heat energy. In return, heat dissipation features may need to be installed.
Many EMI problems can be solved with the use of EMI tape and insulation layer such as a mesh filter. Mesh filters allow for maximum optical performance with minimal reflection. In metal mesh solutions where a film mesh layer is laminated to the back of the glass, EMI tape is used to wrap from the back of the mesh to the front of the glass. EMI tape is cut to CAD specifications and is undetectable when installed.
A busbar is a strip of conductive material that is applied to the edges of a display as an EMI shield. In ITO glass solutions where a sputtered layer of conductive ITO is applied directly to the glass, an AG conductive busbar can be printed from the ITO layer, side of the glass, to the front of the glass. E3 silver epoxy busbars are sized to the bezel width and are not visible when installed.
