An organic light-emitting diode (OLED) device, comprising:
- a substrate;
- a pluralitv of OLEDs defining light-emitting areas formed on the substrate, each OLED comprising a first electrode formed over the substrate, one or more layers of organic material, one of which is light emitting, formed over the first electrode, and a second electrode formed over the one or more layers of organic material;
- a cover provided over the one or more OLEDs and spaced apart from the one or more OLEDs to form a gap;
- and
- a plurality of non-integral, pre-formed elastic compressible, ball-shaped spacer elements located in the gap between the cover and the plurality of OLEDs, within the light-emitting area of each OLED.
