Abstract

The present invention provides a substrate for display and a display device and relates to the technical field of display, aiming at solving the problem of an existing device that the steam isolation effect is poor. The substrate for display comprises an annular packaging region and a display region located on the inner side of the packaging region, wherein the packaging region comprises an annular sticking region and a groove region which is located on the inner side of the sticking region and / or the outer side of the sticking region; and a groove structure is formed in the groove region and a material for absorbing water is stored in the groove structure. The substrate is used for the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED, Organic Light-Emitting Diode) is a kind of all-solid-state, active light-emitting, high brightness, high contrast, ultra-thin and ultra-light, low power consumption, no viewing angle limitation, wide operating temperature range, etc. It is considered to be the next-generation flat-panel display emerging application technology. [0003] The lifespan of OLED devices is a key issue that currently plagues the development of the OLED industry. Through a large number of experiments and analysis, it is found that the main cause of OLED failure is the failure model of the micro-electrolytic cell of the OLED device. Specifically, since the OLED device is a DC current-driven device, when the OLED is in the working state, if there is water vapor inside the device, a miniature elect...
