Problems solved by technology

Due to the thin film encapsulation layer, water vapor and oxygen in the external environment are easy to diffuse from the interface between the encapsulation layers to the inside of the display panel, resulting in the aging failure of the light-emitting material of the organic light-emitting unit and affecting the life of the display panel.

Abstract

The invention discloses a display panel. The display panel includes a substrate, an organic light emitting unit and a thin film encapsulation layer. The substrate includes a display area and a non-display area, the organic light-emitting unit is arranged on the display area of ​​the substrate, and the thin-film encapsulation layer covers the organic light-emitting unit. The thin film encapsulation layer at least includes a first inorganic layer and a second inorganic layer, and the thin film encapsulation layer covers the organic light emitting unit. The display panel further includes a sealing member disposed around the display area, located between the first inorganic layer and the second inorganic layer in the non-display area, and in contact with the first inorganic layer and the second inorganic layer. Through the melting and re-solidification of the sealing member, the bonding between the first inorganic layer and the second inorganic layer and the sealing member can be strengthened, so that water vapor and oxygen in the external environment can be blocked from diffusing from the interface between the thin film encapsulation layers to the inside of the display panel, The encapsulation effect of the thin film encapsulation layer is improved, and the aging and failure of the light-emitting material of the organic light-emitting unit is avoided, thereby prolonging the lifespan of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display panel. Background technique [0002] An organic light emitting diode (Organic Light Emitting Diode, OLED) display device has become an important display device in the display field due to its advantages of thinness, lightness, wide viewing angle, and low cost. [0003] Components such as water vapor and oxygen in the air have a great impact on the life of the light-emitting unit in the OLED display panel. Therefore, when forming an OLED display panel, an encapsulation layer covering the light-emitting unit is provided to prevent components such as water vapor and oxygen from entering the interior of the display panel. , to avoid water vapor and oxygen and other components from damaging the light-emitting unit. In the prior art, the encapsulation layer generally adopts a Thin-Film Encapsulation (TFE) layer, and the widely used TFE layer is ...
