Abstract

In a method of fabricating a flexible display panel, a rigid substrate is provided. A flexible substrate having a first surface and a second surface opposite to the first surface is provided. A plurality of releasing-regions are formed on the first surface, and bonding strength of an area outside the releasing-regions is greater than bonding strength of the releasing-regions. An adhesive layer is formed between the rigid substrate and the first surface of the flexible substrate. A plurality of display units are formed on the second surface, and each of the display units is located over one of the releasing-regions, respectively. The flexible substrate is patterned to obtain a plurality of flexible carriers, and each of the flexible carriers carries one of the display units, respectively. The flexible carriers and the adhesive layer are de-bonded.

Claims (18)

1. A flexible display panel comprising:

a flexible carrier having two surfaces, wherein the flexible carrier comprises a plurality of water-oxygen-resistant flexible carriers bonded to one another through an adhesive material, and each of the water-oxygen-resistant flexible carriers comprises:

a flexible base film; and

a water-oxygen-resistant layer bonded to the flexible base film, wherein the adhesive material contacts and is located between the water-oxygen-resistant layer of one of the water-oxygen-resistant flexible carriers and the flexible base film of another one of the water-oxygen-resistant flexible carriers;

a display unit disposed on and contacting the outmost water-oxygen-resistant layer of the flexible carrier, wherein the display unit comprises:

an active device array layer; and

a display medium layer located on the active device array layer; and

a coating formed on and contacting the outmost flexible base film of the flexible carrier, wherein a material of the coating comprises organic fluoride.

2. The flexible display panel as claimed in claim 1 , wherein the active device array layer of the display unit contacts the outmost water-oxygen-resistant layer of the flexible carrier and is located between the display medium layer of the display unit and the flexible carrier, the coating contacts the outmost flexible base film of the flexible carrier, and the flexible carrier is located between the display medium layer of the display unit and the coating.

3. A flexible display panel comprising:

a flexible carrier having two surfaces, wherein the flexible carrier comprises a plurality of water-oxygen-resistant flexible carriers bonded to one another through an adhesive material, and each of the water-oxygen-resistant flexible carriers comprises:

a flexible base film; and

a water-oxygen-resistant layer bonded to the flexible base film, wherein the adhesive material contacts and is located between the water-oxygen-resistant layer of one of the water-oxygen-resistant flexible carriers and that of another one of the water-oxygen-resistant flexible carriers;

a display unit disposed on and contacting the outmost flexible base film of the flexible carrier, wherein the display unit comprises:

an active device array layer; and

a display medium layer located on the active device array layer; and

a coating formed on and contacting another outmost flexible base film of the flexible carrier, wherein a material of the coating comprises organic fluoride.

4. The flexible display panel as claimed in claim 3 , wherein all of the water-oxygen-resistant layers are located between the outmost flexible base film and the another outmost flexible base film of the flexible carrier.
