Benefits of technology

"The present invention provides a flexible substrate structure and a method of making it to reduce fabrication cost, promote yield rate, and quality of the flexible substrate structure. The flexible substrate structure includes a supporting carrier, flexible substrate, and a release layer. The release layer is in contact with both the supporting carrier and the flexible substrate and has adhesion property for bonding them together and supporting them. The method involves forming a bonding region with adhesion property and a release region without adhesion property in the release layer through a local modification process."

Problems solved by technology

A conventional method of fabricating a flexible display device has encountered a bottleneck of fabricating thin film transistors (TFTs) on a flexible substrate, such as a plastic substrate.
However, the conventional method of directly forming the patterned release layer by performing a vacuum evaporation process causes a high fabrication cost.
As a result, the release layer tends to adhere to the shadow mask, which may cause a peeling problem consequently.

Abstract

A flexible substrate structure includes a supporting carrier, a flexible substrate, and a release layer. The flexible substrate is disposed on the supporting carrier. The release layer is disposed between and in contact with the supporting carrier and the flexible substrate. The release layer includes a bonding region with adhesion property, the bonding region is for bonding the flexible substrate and the supporting carrier together, and a release region without adhesion property, the release region is for supporting the flexible substrate.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a flexible substrate structure and a method of fabricating the same, and more particularly, to a method of fabricating a flexible substrate structure including forming a bonding region with adhesion property and a release region without adhesion property on a release layer with a local modification process, and a flexible substrate structure thereof.[0003]2. Description of the Prior Art[0004]In modern display technologies, flexible display device is distinguished for its characteristics such as light weight, impact endurance, flexibility, wearability, portability, etc. Thus, the flexible display devices are regarded as a foresighted display technology. A conventional method of fabricating a flexible display device has encountered a bottleneck of fabricating thin film transistors (TFTs) on a flexible substrate, such as a plastic substrate.[0005]In accordance with the conventional method o...
