Organic light emitting display apparatus and method of manufacturing the same
A method of manufacturing an organic light emitting display apparatus includes: preparing a substrate having a first surface and a second surface opposite to the first surface; forming a through-hole penetrating the substrate from the first surface to the second surface; forming a humidity preventing layer on the substrate; forming a plurality of organic light emitting diodes on the substrate; and removing an organic light emitting diode adjacent to the through-hole from among the plurality of organic light emitting diodes, in which the humidity preventing layer may be formed on the substrate via a sequential vapor infiltration (SVI) process.
1. An organic light emitting display apparatus comprising:
a substrate having a first surface, a second surface opposite to the first surface, and a through-hole penetrating from the first surface to the second surface;
a humidity preventing layer on the substrate;
a circuit unit on the substrate and comprising an opening unit arranged at a location corresponding to the through-hole; and
an organic light emitting diode on a top portion of the circuit unit,
wherein the substrate comprises an organic material,
wherein the humidity preventing layer comprises an organic/inorganic composite layer comprising an inorganic material and the organic material of the substrate, and
the inorganic material of the humidity preventing layer is in a space formed within the organic material of the substrate, and
wherein the substrate has a third surface perpendicular to the second surface, and the humidity preventing layer is disposed on an outskirt of the substrate directly contacting and completely covering the second and third surfaces.
2. The organic light emitting display apparatus of claim 1 , wherein a width of the opening unit is equal to or less than that of the through-hole.
3. The organic light emitting display apparatus of claim 2 , further comprising a bottom protecting film on a bottom portion of the substrate and a top protecting film on a top portion of the organic light emitting diode, wherein the opening unit penetrates through the top and bottom protecting films.
