Light-emitting display backplane, organic light-emitting display and manufacturing method thereof

Abstract

The invention discloses a light-emitting display backplane, an organic light-emitting display and a manufacturing method thereof. In the invention, the light-emitting display backplane includes several organic light-emitting display devices formed on an array substrate, and a plurality of organic light-emitting display devices arranged between adjacent organic light-emitting display devices. The pixel definition layer between them also includes: several supports formed on the pixel definition layer for supporting the encapsulation substrate opposite to the light-emitting display backplane; wherein the supports include support parts; The cross section of the support part in the direction perpendicular to the plane where the array substrate is located is an inverted trapezoid, the inverted trapezoid is a trapezoid whose upper base is longer than the lower base, and the angle between the lower base and the waist is an obtuse angle. Through the present invention, the contact layer and the electrode layer have separate structures, so that when the contact layer is deformed, the electrode layer is not affected by the deformation, and the stability and reliability of the organic light-emitting display are improved.

Description

technical field [0001] The invention relates to the field of display manufacturing, in particular to a light-emitting display backplane, an organic light-emitting display and a manufacturing method thereof. Background technique [0002] Organic Light Emitting Diode (OLED), because of its self-luminous, fast response, wide viewing angle and other characteristics, OLED-based organic light-emitting displays have become mainstream products in the display field. [0003] The OLED-based organic light-emitting display includes a light-emitting display backplane and a packaging substrate. There is a certain thickness of gap between the light-emitting display backplane and the packaging substrate. In order to avoid the packaging substrate and the light-emitting display backplane due to uneven force during use. As a result of deformation, a support for supporting a package substrate disposed opposite to the light-emitting display backplane is generally provided on the light-emitting d...

Problems solved by technology

Depend on Figure 1A and Figure 1B It can be seen that since the support 1 is a structure with a narrow top and a wide bottom, the contact layer 2 and the electrode layer 3 are a continuous whole. However, the contact layer 2 is in contact with the package substrate. Wear and deformation. At this time, the contact layer 2 and the electrode layer 3 are a continuous whole, which will inevitably cause the electrode layer 3 to be deformed. The deformed electrode layer 3 is located in the light-emitting display area, so it will affect the normal display effect. Reduced stability and reliability of organic light-emitting displays
