Abstract

A manufacturing method for flexible display apparatus includes following steps. A carrier frame is formed on a rigid substrate. A flexible substrate is formed on the carrier substrate, wherein a border of the flexible substrate is supported by the carrier frame. A display unit is formed on the flexible substrate. At least a portion of the flexible substrate is separated from the carrier frame. In the manufacturing method, the flexible substrate and the carrier frame can be easily separated.

Claims (19)

1. A manufacturing method for flexible display apparatus comprising:

forming a carrier frame on a rigid substrate;

forming a flexible substrate on the carrier frame and a border of the flexible substrate being supported by the carrier frame;

forming a display unit on the flexible substrate; and

separating a portion of the flexible substrate from the carrier frame,

wherein the display unit has a display part and a cutting part surrounding the display part, a border between the display part and the cutting part is located at an inner side of the carrier frame, and the method for separating the portion of the flexible substrate from the carrier frame comprises:

cutting the cutting part and a portion of the flexible substrate under the cutting part along the border between the display part and the cutting part.

2. The manufacturing method as claimed in claim 1 , wherein before forming the display unit, the manufacturing method further comprises forming a sealant layer at the rigid substrate along a border of the carrier frame, and the border of the flexible substrate is covered by the sealant layer.

3. The manufacturing method as claimed in claim 1 , wherein the method for forming the carrier frame includes spreading glue or sticking adhesive tape.

4. The manufacturing method as claimed in claim 1 , wherein the method for forming the flexible substrate comprises:

sticking a supporting layer on the carrier frame; and

spreading a substrate layer on the supporting layer.

5. The manufacturing method as claimed in claim 4 , wherein material of the supporting layer and the substrate layer are respectively selected from one of polyethylene terephthalate, polyimide, poly(ethylene-2,-6 naphthalate), polymethylmethacrylate, stainless steel and metal alloy.

6. The manufacturing method as claimed in claim 1 , wherein the method for forming the display unit comprises:

forming a driving circuit layer on the flexible substrate; and

forming a display layer on the driving circuit layer.

7. The manufacturing method as claimed in claim 1 , wherein the method for separating the portion of the flexible substrate from the carrier frame further comprises:

cutting a portion of the rigid substrate under the cutting part while cutting the cutting part and the portion of the flexible substrate under the cutting part.

8. The manufacturing method as claimed in claim 1 , wherein material of the carrier frame is adhesive material.
