Referring to FIG. 1, Fig. 1 shows the partial sectional view of display panel.
This application provides a kind of flexible display panels 2, which includes the first film layer 202 and the second film layer 204,
204 parallel arrangement of first film layer 202 and the second film layer, for example, the first film layer 202 and the second film layer 204 can be flexible base board,
Insulating layer or planarization layer etc..
First film layer 202 and the second film layer 204 are layers of elastomeric film, when flexible display panels 2 from unfolded state convert to
When folded state, the first film layer 202 and the second film layer 204 can produce flexible deformation, conversely, working as flexible display panels 2 from folding
When overlapping state is converted to unfolded state, the first film layer 202 and the second film layer 204 restore deformation.
Referring to FIG. 2, Fig. 2 shows the schematic diagrames that first area and second area are arranged in flexible display panels.
Flexible display panels 2 include first area 206 and second area 208, first area 206 and second area 208 that
