Abstract

The present invention involves a flexible display panel, its production method and display device, which is used to solve the existing flexible display panel. After there are hard objects, the internal membrane layer is prone to crack, causing abnormal problems.The flexible display panel includes: flexible substrate, each functional membrane layer and at least one supporting pillar set on the flexible substrate; each functional membrane layer has multiple layersSet in the non -pixel light -emitting area of the flexible display panel; the hardness of the material of each supporting pillar is greater than the hardness of the organic layer where the supporting pillar is located, and the height is not greater than the thickness of the organic layer where the support pillar is located.The invention sets the supporting pillar with a thickness of no more than its organic layer in the non -pixel emitting area of the organic layer, so it will not only affect the normal display of the display panel and the thickness of the organic layer;The membrane layer has a crack, which in turn improves the ability to resist the display panel.

Description

technical field [0001] The present invention relates to the technical field of display substrates, in particular to a flexible display panel, a manufacturing method thereof and a display device. Background technique [0002] Flexible display, using PHOLED (Phosphorescent Organic Light-Emitting Diode, phosphorescent organic light-emitting diode) technology, has low power consumption, direct viewable flexible panel, made of soft materials, variable shape and bendable display device, in our It has been widely used in our daily life. Flexible electronic devices, especially flexible display panels, have attracted more and more attention because of their thinness, bendability, even folding, and good mechanical properties. However, the existing flexible display panel does not cover the hard glass cover, so when it is bumped by a hard object, the inner film layer is prone to cracks, resulting in abnormal display. [0003] To sum up, when the existing flexible display panel is bump...
