Multi-display apparatus and methods thereof
First Claim
1. A multi-display apparatus comprisinga plurality of unit panels connected to form an image screen, each unit panel comprising:
- a substrate;
a display device on a first surface of the substrate;
a moisture barrier wall contacting the first surface of the substrate, wherein the moisture barrier wall is spaced from an outer periphery of the display device and exposes the display device;
an organic material layer on the substrate and burying the display device inside the moisture barrier wall; and
an inorganic material layer disposed on substantially an entire upper surface of the organic material layer,whereinthe moisture barrier wall has a height greater than a thickness of the organic material layer,an inner wall surface of the moisture barrier wall is in contact with the organic material layer and the inorganic material layer, andan angle between an entire of the inner wall surface of the moisture barrier wall and a surface of the substrate, upon which the moisture barrier wall is formed, is about 90°
or less, so that an end of the organic material layer burying the display device may not extend over the moisture barrier wall.

Abstract
A multi-display apparatus includes a thin film encapsulating structure to prevent moisture penetration through sides of the encapsulating structure. Each of a plurality of unit panels of the multi-display apparatus includes a substrate, a display device formed on the substrate, an organic material layer formed on the substrate to bury the display device, an inorganic material layer stacked on the organic material layer, and a moisture barrier wall that is formed outside the display device on the substrate and has a height greater than a thickness of the organic material layer. The multi-display apparatus having a thin film encapsulating structure can realize a stable, smooth, and large image screen since the thin film encapsulating structure can reduce a width of seams between the unit panels and can prevent moisture penetration.

13. A method of manufacturing a unit panel for a multi-display apparatus, the method comprising:
-
forming a display device on a first surface of a substrate; forming a moisture barrier wall contacting the first surface of the substrate to be spaced from an outer periphery of the display device and to expose the display device; depositing an organic material layer within an area defined by the moisture barrier wall to a height less than a height of the moisture barrier wall, the organic material layer covering the display device and contacting an inner wall surface of the moisture barrier wall; and depositing an inorganic material layer on substantially an entire upper surface of the organic material layer, the inorganic material layer contacting the inner wall surface of the moisture barrier wall, wherein an angle between an entire of the inner wall surface of the moisture barrier wall and a surface of the substrate, upon which the moisture barrier wall is formed, is about 90°
or less, so that an end of the organic material layer burying the display device may not extend over the moisture barrier wall. - View Dependent Claims (14, 15)
