Problems solved by technology

[0004] However, in the actual production process, there will be situations where the etching of inorganic substances in the inorganic cavity is not clean, so the anti-crack effect will be reduced, and the product yield rate is still not high

Embodiment Construction

[0015] Such as figure 1 as shown, figure 1 is a schematic structural view of the display substrate according to the first embodiment of the present invention. In this embodiment, the display substrate 10 includes a display region 11 and a barrier layer 12 .

[0016] The display area 11 is located inside the display substrate 10 , and the barrier layer 12 is located between the display area 11 and the substrate edge of the display substrate 10 . Wherein, the barrier layer 12 is provided with two rows of first hole segments 13 at intervals in the direction from the display area 11 to the edge of the substrate. Each row of first hole segments 13 includes at least two first hole segments 13 arranged at intervals along the extending direction of the edge of the substrate. Moreover, projections of adjacent rows of first hole segments 13 in the extending direction of the substrate edge overlap with each other.

[0017] In this embodiment, the first hole segment 13 is arranged in ...

Abstract

The invention discloses a displaying device and a displaying substrate. The displaying substrate comprises a displaying area located inside the displaying substrate and a barrier layer located betweenthe displaying area and the substrate edge of the displaying substrate, wherein the barrier layer is provided with at least two rows of first hole sections in the direction from the displaying area to the substrate edge in a spaced mode, each row of first hole section comprises at least two first hole section bodies in the extending direction of the substrate edge in a spaced mode, and adjacent rows of first hole section bodies are overlapped with one another on the projection in the extending direction of the substrate edge. Through the mode, a crack can be effectively prevented from expanding, and the product yield is increased.

Description

technical field [0001] The invention relates to the field of displays, in particular to a display device and a display substrate thereof. Background technique [0002] Today, flexible display devices have become a research hotspot in the display industry because of their characteristics of being bendable, impact-resistant, and easy to wear. The emergence of flexible display panels can realize diversified designs of mobile phones and other terminals. However, there are still some problems in the manufacturing process of the flexible display panel that affect the yield of the product. One of the steps, that is, when laser cutting from a large board to a single substrate, many cracks will be generated at the edge of the substrate. Therefore, when the flexible panel is bent or folded, due to the action of external force, the crack will extend to the inside of the substrate, and will extend to the circuit area or even the active area, making the panel unable to emit light normal...
