A method for creating an air gap between first and second layers separated by a third layer comprising the steps of:

• applying an energy signal in order to cause the first and second layers to converge towards each other at a predetermined location resulting in a thinning of the third layer;
• and
• removing the energy signal to thereby permit the first and second layers to rebound to a predetermined distance from each other, leaving an air gap at the predetermined location between the first layer and the thinned third layer.

A method for creating a gap between layers at a pixel location in a display system, wherein the display system comprises a substrate, a first conductor layer on the substrate, a second layer on the first conductor layer, wherein the second layer comprises a material capable of in situ self-sacrifice under compressive strain, and a third conductor layer on the second layer, the method comprising the steps of:

• applying a high frequency electrical signal between the first and third conductor layers at the pixel location in order to cause the first and third conductor layers to converge towards each other resulting in a progressive compression of the second layer.
