Problems solved by technology

In the prior art, the retaining wall mostly adopts a structure in which multiple film layers are stacked. If the alignment of multiple film layers deviates during the preparation process, the height of the retaining wall formed by stacking will deviate, resulting in the blocking of the film packaging layer by the retaining wall. failure, and the spread of the thin film encapsulation layer increases the frame of the display panel

Abstract

The invention discloses a display panel, a display device and a preparation method of the display panel. The display panel comprises a substrate. The substrate comprises a display area and a non-display area surrounding the display area. The non-display area is provided with a retaining wall, and the retaining wall surrounds the display area. The display area is provided with a planarization layer, a pixel definition layer and supporting columns. The pixel definition layer is arranged on one side, far away from the substrate, of the planarization layer. The supporting columns are arranged on one side, far away from the substrate, of the pixel definition layer. The retaining wall, the supporting columns and at least one layer of the pixel definition layer and the planarization layer are made of the same material. According to the scheme of the embodiment of the invention, the preparation precision of the retaining wall is improved. The blocking effect of the retaining wall on a thin film packaging layer is ensured, and the frame of the display panel is reduced.

Description

technical field [0001] The invention relates to display technology, in particular to a display panel, a display device and a method for preparing the display panel. Background technique [0002] Organic Light Emitting Diode (OLED) display panel is a kind of self-luminous display panel. OLED display panel is more and more popular because of its advantages of thinness, high brightness, low power consumption, wide viewing angle, high response speed and wide operating temperature range. It is increasingly used in various high-performance display fields. [0003] In the prior art, a method of thin film encapsulation is often used to ensure that the organic luminescent material and electrodes are not corroded by water vapor and oxygen in the external environment. At the same time, in order to avoid the extension effect of the thin film encapsulation layer from increasing the invalid area around the organic light-emitting structure, barrier walls are often provided around the orga...
