Organic light emitting diode display and manufacturing method thereof

摘要

An organic light emitting diode display and a manufacturing method thereof are provided. The organic light emitting diode display includes a first substrate, a second substrate, a plurality of organic light emitting diodes, and a frit layer. The organic light emitting diodes are disposed on the first substrate, and the frit layer adheres the first substrate and the second substrate to each other. The frit layer includes a first porous region having pores, a second porous region having pores, and a third porous region having pores. The number of the pores of the first porous region with a diameter of larger than or equal to 4 μm and smaller than or equal to 15 μm is greater than the number of the pores of the second porous region with the above-mentioned diameter range.

主权项

1. A display, comprising:
a first substrate having a displaying area; a second substrate; a plurality of organic light emitting diodes disposed between the first substrate and the second substrate; a frit layer disposed between the first substrate and the second substrate and surrounding the organic light emitting diodes, wherein the frit layer comprises: a first porous region having pores and a second porous region having pores, wherein the first porous region and the second porous region are disposed adjacent to each other, and the first porous region is disposed adjacent to the displaying area and located between the second porous region and the displaying area; and an encapsulation layer disposed between the first substrate and the second substrate, wherein the encapsulation layer surrounds and covers the frit layer, and the frit layer is disposed between the organic light emitting diodes and the encapsulation layer; wherein, the number of the pores of the first porous region with a diameter of larger than or equal to 4 μm and smaller than or equal to 15 μm is greater than the number of the pores of the second porous region with the diameter of larger than or equal to 4 μm and smaller than or equal to 15 μm; and wherein a corner portion of the frit layer has a greater density of pores than a straight portion of the frit layer.
