Problems solved by technology

The angle of the formed inverted trapezoid is generally very small, so it is easy to deposit conductive material on the side of the isolation column, so that the adjacent first electrodes are turned on, and the display panel cannot display normally.

Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] In all embodiments of the present invention, the definitions of "layer" and "pattern" and the relationship between them need to be clarified. Wherein, "layer" refers to a layer of thin film made of a certain material on a substrate by deposition or other processes. If the "layer" still needs a patterning process during the entire production process, it is called a "layer" before the patterning process, and it is called a "pattern" after the patterning p...

Abstract

The invention provides an isolating pillar, a manufacturing method of the isolating pillar, a display panel and a display device and relates to the field of display technologies. The problem that every two adjacent strip-shaped electrodes in a plurality of first strip-shaped electrodes formed by an existing isolating pillar are likely to be connected is solved. The isolating pillar comprises a first material pattern and a second material pattern located on the first material pattern. The first material pattern comprises an upper surface, a lower surface, a first isolating side face and a second isolating side face, wherein the upper surface is opposite to the lower surface, and the first isolating side face and the second isolating side face are opposite and are located between the upper surface and the lower surface. The second material pattern comprises an upper surface and a lower surface which are opposite to each other, the upper surface of the first material pattern makes direct contact with the lower surface of the second material pattern, and the projections, in the plane where the lower surface of the second material pattern is located, of the first isolating side face and the second isolating side face of the first material pattern are located among edges of the lower surface of the second material pattern. The isolating pillar is applied to the PMOLED display panel and a manufacturing method thereof.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a spacer column and a manufacturing method thereof, a display panel and a display device. Background technique [0002] At present, in flat panel display technology, organic light emitting diodes have the advantages of self-luminescence, high contrast, high response speed, wide viewing angle, etc., and are playing an increasingly important role in flat panel display technology. As a new generation of display devices, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) has broad development space and application prospects in digital products such as monitors, MP3, TVs, mobile phones, and military fields. [0003] There are mainly two ways of driving OLEDs: active drive and passive drive. The drive control circuit is an essential and important part of active light-emitting diodes, and its performance is directly related to the performance of the entire system. There...
