Abstract

An OLED display includes: a substrate including a display area with a plurality of pixels; an encapsulation substrate at the display area; and a sealant formed along an edge of the encapsulation substrate between the substrate and the encapsulation substrate to bond the substrate to the encapsulation substrate. The sealant includes a plurality of straight line portions and crossing portions formed by two straight line portions crossing each other.

Claims (12)

1. An organic light emitting diode (OLED) display comprising:

a substrate comprising a display area with a plurality of pixels;

an encapsulation substrate at the display area; and

a sealant formed along a periphery of the encapsulation substrate between the substrate and the encapsulation substrate to bond the substrate to the encapsulation substrate,

wherein the sealant comprises,

a plurality of straight line portions and

crossing portions formed by two of the straight line portions crossing each other,

wherein each of the crossing portions is formed in the shape of a cross.

2. The OLED display of claim 1 , wherein the encapsulation substrate comprises four side portions and four corner portions, and the straight line portions are in parallel with the respective side portions of the encapsulation substrate.

3. The OLED display of claim 2 , wherein the straight line portions comprise two parallel first straight line portions and two parallel second straight line portions crossing the first straight line portions, and the crossing portions comprise the first straight line portions and the second straight line portions crossing each other.

4. The OLED display of claim 1 , wherein the sealant comprises a frit melted by a laser beam and then cured.

5. The OLED display of claim 4 , wherein the laser beam comprises a single mode laser beam with a square-shaped spot and square-shaped cross-section energy dispersion for forming the sealant.
