Example Embodiment

[0023] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [up], [down], [front], [rear], [left], [right], [inner], [outer], [side], etc., are only for reference Additional schema orientation. Therefore, the directional terms used are for describing and understanding the present invention, not for limiting the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0024] The present invention is aimed at the flexible display panel of the prior art. Since the inorganic encapsulation layer is mainly in direct contact with the anode and the inorganic layer, the flexible display panel is prone to breakage during bending. This embodiment can solve this defect.

[0025] like figure 1 As shown, the flexible display panel provided by the embodiment of...

Abstract

A flexible display panel provided by the present invention comprises a substrate, a TFT array layer arranged on the substrate and a packaging layer arranged on the TFT array layer, the TFT array layercomprises an inorganic layer, an organic layer is arranged on the TFT array layer located in a non-display area, a hollow structure at least penetrating the organic layer is arranged in the organic layer, and the packaging layer covers the hollow structure. The organic layer comprises a flat layer, a pixel definition layer and a support layer, and the hollow structure comprises grooves with different grooving degrees, so that the bending resistance of the flexible display panel can be improved, and the risk of cracks is reduced; and in addition, cracks can be effectively prevented from extending to the display area to influence the display effect.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display panel. Background technique [0002] In recent years, active-matrix organic light-emitting diode (AMOLED) displays have received extensive attention and applications due to their advantages of high contrast, wide viewing angle, and bendability. The folding feature has attracted the attention of consumers. As the technology becomes more and more mature, bendable display screens are gradually appearing at various booths. [0003] For a bendable display, it is extremely important to ensure that no breakage or peeling occurs after bending. However, for the bendable display in the prior art, the inorganic encapsulation layer of the encapsulation layer in the non-display area is mainly related to the The anode is in direct contact with the inorganic layer. Compared with the organic layer, the inorganic packaging layer has a higher Young's modulus and is bri...
