Problems solved by technology

The organic base layer is usually made of materials with poor water resistance. Part of the side of the organic base layer will be exposed through the hollow groove. Water and oxygen can easily invade the organic base layer from the hollow groove, and then invade the OLED light-emitting unit, which affects the use of the display panel. life

Abstract

The invention discloses a display substrate. The display substrate includes a display area and a hollow groove arranged on the periphery of the display area. The display substrate includes a base structure layer, a light-emitting unit arranged on the base structure layer and located in the display area, and the base structure layer includes a first organic base layer. , the light-emitting unit is disposed on the first organic base layer, the first organic base layer is provided with a groove structure between the hollow groove and the display area, and the display substrate also includes a cover The light emitting unit and the first inorganic encapsulation layer of the groove structure. In the display substrate, the first inorganic encapsulation layer makes the vertical cross-section of the first organic base layer at the position of the groove structure smaller, thereby preventing a part of water and oxygen from invading into the first organic base layer close to the display area, thereby preventing the intrusion of water and oxygen The light emitting unit improves the service life of the display substrate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a preparation method thereof, and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display is a display and lighting technology developed in recent years. It has the advantages of high response, high contrast, and flexibility, and is considered to have broad application prospects. In terms of flexible display, the deformable and bendable characteristics of OLED display devices further reflect the advantages of OLED display itself. [0003] As one of the important development directions of flexible display products, stretchable display devices have attracted extensive attention because they can be applied to wearable devices and even clothing. In the existing stretchable OLED products, the OLED display panel includes a plurality of display areas arranged in an array, each display area is provided with a plurality of OLED li...
