Claim 0:
1. An evaporation method, comprising:
performing a first evaporation on a base substrate by using a first mask to form a first evaporation sub-pattern on the base substrate, wherein the first mask has a first opening area; and
performing a second evaporation on the base substrate by using a second mask to form a second evaporation sub-pattern on the base substrate, wherein the second mask has a second opening area;
wherein a combination of the first and second evaporation sub-patterns forms an evaporation pattern;
wherein the first and second evaporation sub-patterns constitute complementary patterns; and
wherein the first and second evaporation sub-patterns are able to form an evaporation layer having an isolated hollow pattern.
