Abstract

A carrier applicable to a laser releasing process and for carrying at least a flexible display panel is provided. The flexible display panel is formed on a transparent substrate and includes a display main body and a driving circuit module connected to an edge of the display main body. The carrier includes a carrying plate having at least a carrying area for carrying the flexible display panel and a protecting cover disposed on the carrying plate and located at an edge of the carrying area. A receiving space is formed between the protecting cover and the carrying plate for receiving the driving circuit module. The protecting cover is for shielding the driving circuit module to prevent the driving circuit module from being irradiated by a laser beam in the laser releasing process. A method for manufacturing flexible display panel also is provided.

Claims (24)

1. A method for manufacturing flexible display panel, comprising:

forming a flexible display panel on a transparent substrate, the flexible display panel comprising a flexible plate, a display main body and a driving circuit module connected to an edge of the display main body, the display main body comprising a flexible plate;

shielding a portion of the driving circuit module of the flexible display panel, wherein the portion of the driving circuit module is not overlapped with the flexible plate; and

performing a laser releasing process to separate the flexible display panel from the transparent substrate after shielding the portion of the driving circuit module of the flexible display panel.

2. The method according to claim 1 , wherein the step of shielding the driving circuit module comprises:

providing a carrier, the carrier comprising a carrying plate and a protecting cover, the carrying plate having a carrying area, the protecting cover being disposed on the carrying plate and located at an edge of the carrying area, and a receiving space being formed between the protecting cover and the carrying plate; and

disposing the transparent substrate with the flexible display panel formed thereon on the carrying area and positioning the driving circuit module in the receiving space, and the flexible display panel being located between the transparent substrate and the carrying area.

3. The method as claimed in claim 2 , wherein a portion of the carrying plate opposite to the protecting cover has at least one opening, and the method of shielding the driving circuit module further comprises a step of positioning at least an electronic component of the driving circuit module in the opening.

4. The method as claimed in claim 1 , wherein the step of performing the laser releasing process comprises irradiating the transparent substrate and the flexible display panel by a laser beam from a side of the transparent substrate facing away from the flexible display panel.

5. The method as claimed in claim 4 , wherein the laser beam has a wavelength in a range from 300 nanometers to 400 nanometers.

6. The method as claimed in claim 4 , wherein the laser beam has a pulse energy in a range from 250 millijoules to 700 millijoules.

7. The method as claimed in claim 1 , wherein the flexible display panel is an electrophoretic display panel.

8. A method for manufacturing flexible display panel, comprising:

forming a flexible display panel on a transparent substrate, the flexible display panel comprising a display main body and driving circuit module connected to an edge of the display main body;

shielding the driving circuit module of the flexible display panel; and

performing a laser releasing process to separate the flexible display panel from the transparent substrate,

wherein the step of shielding the driving circuit module comprises:

providing a carrier, the carrier comprising a carrying plate and a protecting cover, the carrying plate having a carrying area, the protecting cover being disposed on the carrying plate and located at an edge of the carrying area, and a receiving space being formed between the protecting cover and the carrying plate; and

disposing the transparent substrate with the flexible display panel formed thereon on the carrying area and positioning the driving circuit module in the receiving space, and the flexible display panel being located between the transparent substrate and the carrying area.

9. The method as claimed in claim 8 , wherein a portion of the carrying plate opposite to the protecting cover has at least one opening, and the method of shielding the driving circuit module further comprises a step of positioning at least an electronic component of the driving circuit module in the opening.

10. The method as claimed in claim 8 , wherein the step of performing the laser releasing process comprises irradiating the transparent substrate and the flexible display panel by a laser beam from a side of the transparent substrate facing away from the flexible display panel.

11. The method as claimed in claim 10 , wherein the laser beam has a wavelength in a range from 300 nanometers to 400 nanometers.

12. The method as claimed in claim 10 , wherein the laser beam has a pulse energy in a range from 250 millijoules to 700 millijoules.

13. The method as claimed in claim 8 , wherein the flexible display panel is an electrophoretic display panel.
