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 structure comprises a display region and a hollow slot arranged at the periphery of the display region; the display substrate comprises a basestructure layer, a light-emitting unit arranged on the base structure layer and located at the display region; the base structure layer comprises a first organic base layer, the light-emitting unit isarranged on the first organic base layer, a groove structure located between the hollow slot and the display region is formed on the first organic base layer; the display substrate further comprisesa first inorganic package layer for covering the light-emitting unit and the groove structure. Through the display substrate disclosed by the invention, the first inorganic package layer enables the vertical section of the first organic base layer to be reduced in a groove structure location, thereby preventing a part of water oxygen from intruding into the first organic base layer close to the display region, and then preventing the water oxygen from intruding into the light-emitting unit, and improving 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...
