Problems solved by technology

Bending does less damage to organic and metal materials on flexible displays, but damage to inorganic oxides such as ITO, SiOx, and SiNx is relatively more serious, especially when bending to a small radius of curvature, it is easy to cause the above-mentioned Faults such as cracking and peeling dislocation of flexible array substrates of inorganic oxides, such as Figure 1a Shown is the large curvature bending state of the flexible array substrate, Figure 1b The figure shows the small curvature bending state of the flexible array substrate, and the figure shows the peeling and dislocation phenomenon of the flexible array substrate, that is, the TFT structure of the flexible array substrate is peeled and dislocated from the substrate

Embodiment 1

[0026] Such as Figure 2a As shown, a flexible array substrate 100 has an elastic organic protective layer 120 on the passivation layer 110 of the flexible array substrate 100, and the elastic organic protective layer 120 is used to prevent the flexible array substrate 100 from being excessively bent, thereby avoiding Cracking, peeling and misalignment caused by excessive bending.

[0027] Specifically, the elastic organic protective layer 120 is composed of a plurality of dispersed elastic bodies 121, and the plurality of elastic bodies 121 are respectively connected to the corresponding pixel electrodes 140 corresponding to the thin film transistors 130 of the flexible array substrate 100. , that is, the plurality of elastic bodies 121 are located at the position where the flexible array substrate 100 is most likely to be cracked and peeled off. Figure 1b shown in small curvature bends) when, as Figure 2b As shown, the elastic body 121 is squeezed to generate elastic for...

Embodiment 2

[0032] Such as Figure 3a As shown, this embodiment also discloses a flexible array substrate 100, the flexible array substrate 100 is similar to the solution of the first embodiment, and the repeated technical content disclosed in the first embodiment will not be described again, specifically, this embodiment is the same as The difference of the first embodiment is that the elastic body 121 constituting the elastic organic protective layer 120 is a rubber column with a spherical top. The bending protection state of this embodiment is as Figure 3b shown.

[0033] The rubber posts and the passivation layer 110 of the flexible array substrate 100 are integrally formed by a photolithography process, that is, when the passivation layer 110 of the flexible array substrate 100 is processed by a photolithography process, the The above-mentioned rubber columns are photolithographically molded as a part of the passivation layer 110 to form the passivation layer 110 with rubber colum...

Abstract

The invention relates to the field of flexible display, in particular to a flexible array substrate with an elastic organic protective layer and a flexible display device with the flexible array substrate. The elastic organic protective layer is arranged on a passivating layer of the flexible array substrate and is used for preventing the flexible array substrate from being excessively bent. According to the flexible array substrate and the flexible display device with the flexible array substrate provided by the invention, when the display device is bent to a small curvature easy for malfunction, the elastic protective layer of the flexible array substrate is extruded for generating bounciness, and the bounciness is capable of preventing the flexible display device from being excessively bent, so that the flexible display device is further protected against a cracking and stripping staggered fault due to excessive bending.

Description

technical field [0001] The present invention relates to the field of flexible display, in particular to a flexible array substrate and a flexible display device having the flexible array substrate. Background technique [0002] Among various existing display devices, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) displays have lighter and thinner appearance designs, wider viewing angles, faster response speeds and lower power consumption. Power consumption and other characteristics make flexible display screens a new development direction for display screens. Bending does less damage to organic and metal materials on flexible displays, but damage to inorganic oxides such as ITO, SiOx, and SiNx is relatively more serious, especially when bending to a small radius of curvature, it is easy to cause the above-mentioned Faults such as cracking and peeling dislocation of flexible array substrates of inorganic oxides, such as Figure 1a Shown is the large curvat...
