Embodiment Construction

[0048] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0049] An embodiment of the present disclosure provides a display panel, refer tofigure 1 , is a schematic plan view of the display panel in this embodiment, AA represents the display area, and the area outside AA is the peripheral area. figure 2 It is a partial structural schematic diagram of the cross-sectional view of the display panel in this embodiment. The vertical dotted line in the figure is used to distinguish the di...

Abstract

The invention provides a display panel, a preparation method thereof and a display device. The display panel comprises a substrate, an insulating layer is arranged in the peripheral area of the substrate, at least one packaging dam is arranged on the side, away from the substrate, of the insulating layer, the packaging dam is located in the peripheral area of the substrate and surrounds a displayarea, and at least one groove is formed in the insulating layer and surrounds the display area, wherein the projection of the at least one groove on the substrate is located in the projection of the packaging dam on the substrate. The groove can slow down or prevent a crack from extending towards the display area, and the packaging effect is improved. Meanwhile, because the groove is arranged below the packaging dam, the width of the peripheral area can be reduced, and the screen-to-body ratio is improved.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular, to a display panel and a manufacturing method thereof, and also to a display device. Background technique [0002] Organic light-emitting display panel (OLED, organic light-emitting diode) is a self-luminous display, which has the advantages of low power consumption, fast response, high luminous efficiency, high brightness, and wide viewing angle, and can meet the requirements of thinning, light weight, and portability. and high performance requirements. [0003] As users pursue higher and higher display effects, increasing the screen-to-body ratio is one of the mainstream design directions. At present, the main design is to expand the display area and increase the screen-to-body ratio by designing special-shaped screens (such as Qi Liu Hai, beauty point, etc.). The size of the frame can be reduced by optimizing the circuit layout of the peripheral area to increase the s...
