A substrate, comprising a metal foil, wherein
- a metal material used for the metal foil is capable of being anodized and a plurality of concave light trapping microstructures is formed on a surface of the metal foil.
An organic light emitting diode display device, comprising a substrate comprising a metal foil, wherein a metal material used for the metal foil is capable of being anodized and a plurality of concave light trapping microstructures are formed on a surface of the metal foil.
A method for fabricating a substrate, comprising:
- providing a metal foil;
- oxidizing the metal foil to form a plurality of metal oxide layers with periodically varying thickness on a surface of the metal foil;
- and
- peeling off the metal oxide layers by an acidic solution and forming a plurality of concave light trapping microstructures on the surface of the metal foil at the same time.
