Light-emitting display back panel, organic light emitting displayer and manufacturing method of light-emitting display back panel and organic light emitting displayer

Abstract

The invention discloses a light-emitting display back panel, an organic light emitting displayer and a manufacturing method of the light-emitting display back panel and the organic light emitting displayer. The light-emitting display back panel comprises a plurality of organic light emitting displayers formed on an array substrate and pixel definition layers between adjacent organic light emitting displayers. The light-emitting display back panel further comprises a plurality of supporting objects which are formed on the pixel definition layers and used for supporting packaging substrates arranged opposite to the light-emitting display back panel. Each supporting object comprises a supporting part, the cross sections of the supporting parts in the direction perpendicular to a plane where the array substrate is located are in inverted trapezoidal shapes which are trapezoids, the trapezoids are characterized in that the lengths of the upper bottoms of the inverted trapezoidal shapes are larger than the lengths of the lower bottoms of the inverted trapezoidal shapes, and included angles between the lower bottoms and the slant edges are obtuse angles. According to the light-emitting display back panel, the organic light emitting displayer and the manufacturing method, a contact layer and an electrode layer are of a discrete structure, the electrode layer cannot be influenced by deformation when the contact layer is deformed, and the stability and the reliability of the organic light emitting displayer 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), due to its characteristics of self-luminescence, fast response, and wide viewing angle, 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 gap of a certain thickness between the light-emitting display backplane and the packaging substrate. In order to cause deformation, a support for supporting the packaging substrate disposed opposite to the light-emitting display backplane is generally arranged on the light-emitting display backplane. [0004] Figure 1A and Figure 1B It is a schematic diagram of the structure of an exist...

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
