Passivation layer for flexible display

A method comprising:

• providing a flexible substrate having an array of display elements configured to emit or modulate light disposed on the flexible substrate;
• forming a passivation layer on the array of display elements to protect the array of display elements from environmental hazards, the passivation layer including molecules of silicon (Si) bonded with oxygen (O) or nitrogen (N);
• forming an anode layer on the flexible substrate;
• and
• forming a cathode layer on the anode layer, wherein the array of display elements are disposed between the anode layer and the cathode layer.

A flexible display comprising:

• a flexible substrate;
• an array of display elements disposed on the flexible substrate and configured to emit or modulate light;
• and
• a passivation layer including molecules of silicon (Si) bonded with oxygen (O) or nitrogen (N), the passivation layer being disposed on the array of display elements to protect the array of display elements from environmental hazards, wherein the passivation layer comprises multiple sub-layers including a first sub-layer including silicon oxide or silicon nitride and a second sub-layer including a material having a different chemical composition than material of the first sub-layer.

A flexible display comprising:

• a flexible substrate;
• an array of display elements disposed on the flexible substrate and configured to emit or modulate light;
• and
• a passivation layer including molecules of silicon (Si) bonded with oxygen (O) or nitrogen (N), the passivation layer being disposed on the array of display elements to protect the array of display elements from environmental hazards, wherein the passivation layer is doped with a material other than Si, O, or N, is flexible and transparent and has a thickness ranging from 100 angstroms to 100 microns.
