Flexible display apparatus and manufacturing method thereof
A flexible display apparatus including a flexible display panel, at least one flexible circuit board, at least one driving chip, and a sealing layer is provided. The flexible display panel has a display area and a bonding area located outside the display area. The flexible circuit board is disposed in the bonding area of the flexible display panel. The driving chip is disposed on the flexible circuit board. The sealing layer encapsulates a periphery of the flexible display panel and extendedly covers the bonding area and a portion of the flexible circuit board.
1. A manufacturing method of a flexible display apparatus, comprising:
providing a rigid substrate;
bonding a flexible display panel to the rigid substrate, wherein the flexible display panel has a display area and a bonding area located outside the display area;
at least one driving chip is bonded to the bonding area of the flexible display panel via at least one flexible circuit board;
forming a sealing layer to encapsulate a periphery of the flexible display panel, wherein the sealing layer extendedly covers the bonding area of the flexible display panel and a portion of the flexible circuit board; and
separating the flexible display panel from the rigid substrate.
2. The manufacturing method of the flexible display apparatus as recited in claim 1 , wherein the step of bonding the flexible display panel to the rigid substrate comprises:
forming an adhesive layer on the rigid substrate; and
laminating the flexible display panel onto the adhesive layer, wherein the flexible display panel is bonded to the rigid substrate via the adhesive layer.
3. The manufacturing method of the flexible display apparatus as recited in claim 1 , wherein the driving chip is disposed on the flexible circuit board, and a location of the driving chip does not overlap with a location of the flexible display panel.
4. The manufacturing method of the flexible display apparatus as recited in claim 1 , wherein the flexible circuit board is bonded to the bonding area of the flexible display panel via an anisotropic conductive film.
5. The manufacturing method of the flexible display apparatus as recited in claim 1 , further comprising:
before separating the flexible display panel from the rigid substrate, performing a heating step or an ultra-violet light illumination step to cure the sealing layer.
6. The manufacturing method of the flexible display apparatus as recited in claim 1 , further comprising:
after separating the flexible display panel from the rigid substrate, bonding an external circuit to the flexible circuit board, wherein the flexible display panel is electrically connected to the external circuit via the flexible circuit board.
