Organic luminescent display and manufacturing method thereof

Abstract

The invention discloses a organic light display, it includes: a basal plate, a glue layer, which is formed on the frame of the basal plate, there is at least one corner of the frame has a gap. The invention also includes the producing method of the organic light display.

Description

technical field [0001] The invention relates to a photoelectric device, in particular to an organic light-emitting display and a manufacturing method thereof. Background technique [0002] Generally speaking, after long-term use of organic light-emitting displays, moisture in the environment can easily penetrate into the display through the interface between the back cover and the substrate. Since the component electrodes are usually made of highly active metals, the It reacts with the water vapor infiltrated into the display, and the structure of the metal layer itself is relatively loose, and the water vapor will affect the light-emitting elements of the lower layer through this path, causing phenomena including peeling or material cracking between the metal electrode and the organic light-emitting layer , leading to the generation of dark spots, greatly reducing the luminous intensity and uniformity of the organic light-emitting display, and reducing the life of the devic...

Problems solved by technology

When the substrates are pressed together, as shown in Figure 1c, due to the increase in the internal gas pressure, it is easy to cause the width of the sealant layer at the joint 14 to be too large, resulting in the overflow of the sealant

[0006] Or reserve a wider gap on the path covering the sealant layer (non-corner position) whose starting point and end point will not extend to the outside to release gas. Although it is more conducive to the discharge of gas, the diffusion path of the sealant layer is still Affected by the released gas, it is difficult to control the optimal width of the gap, and there is a problem that the gap is too wide or too narrow. If the gap is too wide, the width of the joint of the sealant layer may be insufficient, or even appear. If the joint cannot be joined, if the reserved gap is too small, the sealant layer will often be broken due to the sudden increase of internal pressure
