Problems solved by technology

[0003] In the long-term research and development process, the inventors of the present application have found that the adhesion between the organic layer and the inorganic layer of the thin film package is small, and during the bending and folding process of the flexible display panel, the adhesion between the organic layer and the inorganic layer is reduced, and it is easy to peel off each other , reduce the water and oxygen barrier ability, and even lead to the failure of thin film packaging, so that water and oxygen can invade the internal device structure, affecting the life of the flexible display panel

Embodiment Construction

[0027] In order to make the purpose, technical solution and effect of the present application more clear and definite, the present application will be further described in detail below with reference to the accompanying drawings and examples.

[0028] The present application provides a flexible display panel, which includes a thin film encapsulation layer, and the thin film encapsulation layer includes an organic encapsulation layer and an inorganic encapsulation layer. Among them, a plurality of grooves are provided on the side of the organic packaging layer away from the light-emitting layer, and the inorganic packaging layer material fills the grooves, so that the inorganic packaging material is embedded in the organic packaging material, which can strengthen the gap between the organic packaging layer and the inorganic packaging layer. Especially in the bending process of the display panel, it can prevent the peeling between layers, thereby improving the packaging performan...

Abstract

The invention discloses flexible display panels, display equipment and preparation methods for the flexible display panels. A flexible display panel comprises a light-emitting layer, and a first organic packaging layer and a second inorganic packaging layer which are set at one side of the light-emitting layer in sequence. A plurality of grooves are set at one side of the first organic packaging layer away from the light-emitting layer. The second inorganic packaging layer covers the first organic packaging layer and fills up the grooves. Material density of the parts of the first organic packaging layer corresponding to the groove is greater than that of the rest part. In the mode, according to the flexible display panels, the display equipment and the preparation methods for the for flexible display panels, the adhesive force between thin film packaging layers can be improved, and the layers are prevented from being stripped with each other.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a flexible display panel, a display device and a manufacturing method thereof. Background technique [0002] With the development of display technology, flexible display technology has received extensive attention as a new technology in the display field. For example, flexible and foldable organic light-emitting diode (Organic Light-Emitting Diode, OLED) display is one of the current hot development trends. Generally, in order to prevent water and oxygen from contacting and corroding OLED light-emitting materials, it is necessary to use thin film encapsulation (TFE) to encapsulate OLED devices. [0003] In the long-term research and development process, the inventors of the present application have found that the adhesion between the organic layer and the inorganic layer of the thin film package is small, and during the bending and folding process of the flexible displ...
