Flexible display panel and manufacturing method thereof, and flexible display apparatus

A flexible display apparatus, comprising a flexible display panel, the flexible display panel comprising:

• a flexible substrate, the flexible substrate comprising:
• a display area;
• a peripheral area, surrounding a periphery of the display area;
• a welding area, on one side of the peripheral area distal to the display area;
• and
• a bending area, between the peripheral area and the welding area, the bending area being configured to be bent along a bending axis, the bending area comprising a first edge;
• a barrier, on the flexible substrate, the barrier being in the peripheral area and surrounding the periphery of the display area;
• and
• an organic insulation layer, on the flexible substrate,
• wherein the peripheral area comprises a peripheral transition area between the bending area and the display area, the organic insulation layer in the peripheral transition area is provided with a first groove, the first groove is on one side of the barrier distal to the display area and extends along a direction substantially parallel to the bending axis, and the first groove is on one side of the first edge proximal to the display area,
• wherein the peripheral transition area comprises a first fanout area, and an orthographic projection of the first groove on the flexible substrate partially overlaps with the first fanout area,
• wherein the flexible substrate further comprises:
• a second fanout area, between the bending area and the welding area, the second fanout area abutting on the bending area,
• wherein the organic insulation layer between the bending area and the welding area is provided with a second groove, and an orthographic projection of the second groove on the flexible substrate partially overlaps with the second fanout area,
• wherein the first groove is on one side of the barrier distal to the display area, and
• wherein the bending area further comprises a second edge, the second edge is disposed opposite to the first edge, extending directions of the second edge and the first edge are same, and the second groove is on one side of the second edge proximal to the welding area and extends along a direction substantially parallel to the bending axis.

A method for manufacturing a flexible display panel, comprising:

• providing a flexible substrate, the flexible substrate comprising:
• a display area;
• a peripheral area, surrounding a periphery of the display area;
• a welding area, on one side of the peripheral area distal to the display area;
• and
• a bending area, between the peripheral area and the welding area, the bending area being configured to be bent along a bending axis, the bending area comprising a first edge, wherein the peripheral area comprises a peripheral transition area between the bending area and the welding area;
• forming a barrier on the flexible substrate, the barrier being in the peripheral area and surrounding the periphery of the display area;
• forming an organic insulation layer on the flexible substrate;
• and
• forming a first groove in the organic insulation layer in the peripheral transition area, the first groove being on one side of the barrier distal to the display area and extending along a direction parallel to the bending axis, and the first groove being on one side of the first edge proximal to the display area,
• wherein the first groove is formed through a patterning process performed on the organic insulation layer by using a dual-tone mask.
