Foldable Display Antenna Layout for Uncovered 5G Signal Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with integrated antennas face challenges in maintaining effective signal transmission and reception, especially when folded, due to potential coverage by the device's housing or limited exposure of the antenna.
Innovation Solution
The display device incorporates an antenna design that is strategically positioned on an exposed area of the first non-folding display area, ensuring it remains uncovered when the device is folded. This design includes a ground pattern larger than the antenna pattern and an auxiliary pattern for sensing external inputs, all integrated within a sensor layer and display layer configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is integrated within the display device housing, then the device structure is compact and protected, but the antenna coverage is reduced and signal transmission deteriorates when folded
Solution Approach 1:
The antenna is extracted from the conventional housing-integrated position and repositioned to be disposed on the exposed area of the first non-folding display area. This extraction allows the antenna to maintain effective signal transmission by avoiding coverage from folded housing parts while preserving device compactness through strategic positioning on the display surface.
2Reliability
If the antenna is positioned on the folded display area, then the antenna is protected by housing when folded, but the antenna coverage is reduced and signal reception deteriorates
Solution Approach 1:
Instead of positioning the antenna on the folded display area where it would be protected but covered, the invention inverts the approach by disposing the antenna on the exposed area of the first non-folding display area. This inversion ensures the antenna remains uncovered and exposed for effective signal transmission while the folding display area is folded, resolving the contradiction between protection and exposure.
3Reliability
If the ground pattern size is increased to improve signal transmission, then the antenna performance is enhanced, but the available display area is reduced
Solution Approach 1:
The ground pattern is configured with a size greater than the antenna pattern in the local region where the antenna is disposed on the exposed area. This local enhancement of ground pattern size improves antenna performance and signal transmission in the specific location without significantly reducing the overall display area, as the ground pattern is confined to the antenna region rather than expanding across the entire display surface.

AI summary
An embodiments may be related to a display device. A display device may include display layer and an antenna. The display layer may comprise a first display area including an exposed area and a cover area, a folding display area adjacent to the first display area, and a second display area adjacent to the folding area. The antenna disposed on the exposed area of the first display area, wherein the second display area covers the cover area of the first display area and exposes the exposed area of the first display area, when the folding display area is folded.
