1. An electronic device comprising:
a substrate;
an array of display pixels arranged on the substrate in a light-emitting first area, wherein a periphery of the first area is adjacent to a non-light-emitting second area;
a plurality of capillary-flow-inducing structures that are formed over the substrate in the second area, wherein the plurality of capillary-flow-inducing structures comprises a plurality of periodically spaced rectangular strips;
a first passivation layer that is formed over the array of display pixels and the plurality of capillary-flow-inducing structures;
a planarization layer that is formed over the first passivation layer; and
a second passivation layer that is formed over the planarization layer.
