Claim 14:
15. A manufacturing method for a package cover plate, comprising:
forming a cover plate structure layer;
forming a spacer structure on a side of the cover plate structure layer, the spacer structure comprising a first spacer on a side of the cover plate structure layer, the first spacer comprising a water absorbing structure, the water absorbing structure comprising a material of the first spacer doped with desiccant particles; and
forming an auxiliary electrode layer on a side of the spacer structure facing away from the cover plate structure layer,
wherein the forming a spacer structure on a side of the cover plate structure layer further comprises:
forming a second spacer on a side of the first spacer facing away from the cover plate structure layer, an orthographic projection of the second spacer on the cover plate structure layer covering an orthographic projection of the first spacer on the cover plate structure layer; and
performing lyophobic treatment on at least a part of a surface of the second spacer facing away from the first spacer to form a lyophobic layer on a side of the second spacer facing away from the cover plate structure layer,
wherein at least one of tetrafluoromethane, fluorinated silane, and chlorosiloxane is used to perform lyophobic treatment on the second spacer.
