Abstract

The invention provides an organic light-emitting diode display panel and a display. A protection layer additionally disposed on an inorganic layer on a retaining wall is used to prevent an inorganic layer crack from continuously growing, and therefore product sealing performance is improved, and product bending performance is improved. The organic light-emitting diode comprises a display area and an adjacent peripheral area. The display panel comprises a substrate, a display function layer, and a packaging layer. The display area comprises a display function layer, and the peripheral area comprises a first retaining wall, which is disposed around the display area. The packaging layer comprises at least one inorganic layer, which is vertical to the direction of the substrate, and is used to cover the first retaining wall. The display panel comprises the protection layer, which is vertical to the direction of the substrate, and is used to cover the at least one inorganic layer on the upper part of the first retaining wall.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an organic light emitting diode display panel and a display. Background technique [0002] The existing organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel includes a display function layer and an encapsulation layer located on the display function layer, but in the display panel manufacturing process, thin film encapsulation (Thin Film Encapsulation, TFE ), the encapsulation layer is less effective in blocking water and oxygen. Contents of the invention [0003] The embodiment of the present application provides an organic light emitting diode display panel and a display, which are used to prevent the cracks of the inorganic layer from continuing to grow through the protective layer added on the inorganic layer above the retaining wall, thereby improving the sealing performance of the product, and can also improve Product bendability. ...
