FOLDABLE DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18517256 titled 'FOLDABLE DISPLAY DEVICE
Simplified Explanation:
This patent application describes a foldable display device with a unique design to prevent visible bubbles from forming during folding operations.
- The display panel of the device has a folding area, non-folding areas, and a cover window.
- A bonding layer is placed between the cover window and the display panel, protruding in the folding area to prevent visible bubbles.
- The design aims to reduce defects caused by repeated folding operations.
Key Features and Innovation:
- Display panel with folding and non-folding areas.
- Cover window smaller than the display panel.
- Bonding layer prevents visible bubbles during folding.
Potential Applications:
The technology can be applied in the development of foldable electronic devices such as smartphones, tablets, and laptops.
Problems Solved:
The technology addresses the issue of visible bubbles forming during folding operations in foldable display devices.
Benefits:
- Improved durability of foldable display devices.
- Enhanced user experience with seamless folding operations.
Commercial Applications:
The technology can be utilized by electronic device manufacturers to create more reliable and visually appealing foldable devices, potentially increasing market competitiveness.
Questions about Foldable Display Device:
1. How does the design of the bonding layer prevent visible bubbles during folding operations? 2. What are the potential long-term benefits of this technology in the consumer electronics market?
Original Abstract Submitted
A foldable display device includes a display panel including a display area and a non-display area configured to surround the display area, the display panel including a folding area defined in the display area and the non-display area, and non-folding areas disposed at two opposite sides in the folding area; a cover window disposed on the display panel and having a smaller size than the display panel; and a bonding layer disposed between the cover window and the display panel and configured to adjoin a bottom surface of the cover window, in which an end of the bonding layer in the folding area protrudes beyond an end of the bonding layer disposed in the non-folding areas in a direction of a folding axis. Therefore, even though bubbles are formed by repeated folding operations in the folding reliability test, the bubbles cannot be visible from the outside, thereby reducing the defect rate.
