Display panel and method of manufacturing the same
Systems and methods are described for a display panel and a method of manufacturing the display panel. The systems and methods may provide for a substrate having a first surface and a second surface that face each other, a display unit including an organic light-emitting device arranged on the first surface of the substrate; and a thin-film encapsulation layer arranged on the display unit to shield the display unit, wherein an edge of the first surface or an edge of the second surface are inclined with respect to the first surface or the second surface. The inclined surfaces are designed to prevent damage to the display due to fine cracks during the manufacturing process as the display panel is trimmed or cut from a single base member. A display panel having improved strength characteristics may be manufactured, as well.
1. A display panel comprising:
a substrate having a first surface, a second surface substantially parallel to the first surface, and a third surface substantially perpendicular to at least one of the first surface and the second surface;
a display unit including an organic light-emitting device arranged on the first surface of the substrate; and
a thin-film encapsulation layer arranged on the display unit to shield the display unit,
wherein an edge between the first surface and the third surface is inclined with respect to the first surface,
wherein the display unit is between the thin-film encapsulation layer and the substrate,
wherein the substrate includes a first area on which the display unit and the thin-film encapsulation layer are arranged, and a second area including the third surface, a portion of the first surface, and the edge between the first surface and the third surface, and
wherein the display unit and the thin-film encapsulation layer are not arranged on the second area.
2. The display panel of claim 1 , wherein a distance from a starting point of the inclined edge of the first surface to the third surface of the substrate is 5 μm or greater.
3. The display panel of claim 1 , further comprising a protection unit arranged on the thin-film encapsulation layer to shield the thin-film encapsulation layer, wherein the protection unit is not overlapping the second area.
4. The display panel of claim 3 , wherein
the first area is shielded by the protection unit; and
the second area is not overlapping the first area and at least one of an adhesive, cerium dioxide (CeO 2 ), diamond, silicon carbide (SiC), and an ionic component of a surfactant is arranged on the second area.
5. The display panel of claim 3 , wherein the protection unit comprises:
an adhesive arranged on the thin-film encapsulation layer; and
a protection film arranged on the adhesive.
6. A display panel comprising:
a substrate having a first surface, a second surface opposite the first surface, and a third surface substantially perpendicular to at least one of the first surface and the second surface;
a display unit including an organic light-emitting device arranged on the first surface of the substrate; and
a thin-film encapsulation layer arranged on the display unit to shield the display unit,
wherein the first surface comprises a chamfered edge adjacent to the third surface,
wherein the display unit is between the thin-film encapsulation layer and the substrate,
wherein the substrate includes a first area on which the display unit and the thin-film encapsulation layer are arranged, and a second area including the third surface, a portion of the first surface, and the chamfered edge adjacent to the third surface, and
wherein the display unit and the thin-film encapsulation layer are not arranged on the second area.
7. The display panel of claim 6 , wherein the display unit is in direct contact with the substrate.
