Problems solved by technology

[0004] However, when the thickness of the substrate of the light-emitting display is reduced to no more than about 0.3 mm to reduce the thickness of the light-emitting display, it is difficult to maintain the mechanical integrity of the device under stress such as dropping and twisting
Lack of mechanical integrity can compromise the hermetic state of the device, shortening the lifetime of OLEDs

Embodiment Construction

[0028] Hereinafter, specific exemplary embodiments will be described with reference to the accompanying drawings. Here, when a first element is referred to as being coupled to a second element, the first element may not only be directly coupled to the second element, but may also be indirectly coupled to the second element through one or more third elements. Also, for clarity, elements not necessary for a complete understanding have been omitted. Furthermore, like reference numerals refer to like elements throughout.

[0029] In order to prolong the lifetime of the organic light emitting display, some embodiments use an inorganic sealing material that effectively prevents moisture and / or oxygen from permeating. However, when an inorganic sealing material is used, mechanical reliability deteriorates in some embodiments.

[0030] Accordingly, some embodiments provide a light emitting display using an inorganic sealing material that effectively prevents moisture and / or oxygen f...

Abstract

The invention discloses a light emitting display and a method of manufacturing the same, wherein the light emitting display includes a first substrate on which a plurality of light emitting devices is formed, a second substrate provided to face the first substrate, a dam member provided between the first substrate and the second substrate to surround the plurality of light emitting devices, an inorganic sealing material provided between the first substrate and the second substrate on an outer circumference of the dam member to attach the first substrate and the second substrate to each other, and a filling material provided on an internal side of the dam member to cover the plurality of light emitting devices. The inorganic sealing material effectively shields moisture or oxygen and / or increases the life of the light emitting display. The filling material fills the space between the substrates to improve mechanical reliability.

Description

technical field [0001] The present invention relates to a light-emitting display and a manufacturing method thereof, more particularly, to a light-emitting display sealing member containing an inorganic sealing material and a manufacturing method thereof. Background technique [0002] Since light emitting devices such as organic light emitting diodes (OLEDs) include organic materials that are susceptible to moisture and / or oxygen, there is a need to protect OLEDs from moisture and / or oxygen. [0003] Since light-emitting displays using OLEDs generally have a wide viewing angle, high contrast ratio, and fast response speed as well as low power consumption, light-emitting displays are widely used in personal portable devices (e.g., whether they are damaged by moisture and / or oxygen) MP3 players, mobile phones, and television (TV)). The thickness of the light-emitting display has been gradually reduced according to user's needs. [0004] However, when the thickness of the sub...
