Abstract

The invention discloses a flexible display panel which comprises a flexible substrate comprising a display area and a bending area located at one side of the display area; the flexible substrate positioned in the bending area is bent towards one side far away from the light emitting surface of the flexible display panel; a first supporting layer is further arranged on the face, facing the inner side of the bending area, of the flexible substrate, a protruding structure is arranged on the side, close to the bending area, of the first supporting layer, and the protruding structure of the first supporting layer makes contact with a second supporting layer in the flexible substrate, wherein the protruding structure of the first supporting layer supports the bending area.

Description

technical field [0001] The present application relates to the technical field of displays, in particular to a flexible display panel. Background technique [0002] With the development of display technology, narrow borders and high screen-to-body ratio of display panels have become a major trend. [0003] Flexible OLED display technology continues to mature, and the types of flexible display products continue to diversify. Borderless display products have become the mainstream of the market, and their process requirements are getting higher and higher, among which panel bending technology has become the key to determine the yield rate. In order to realize the narrow frame and high screen-to-body ratio of the display panel, it is necessary to bend the non-display area of ​​the display panel to the side opposite to the light-emitting surface. In the prior art, the panel bending process is to bend the flexible OLED display panel area and attach it to the back of the display p...
