Solution Overview

Problem

As display apparatuses increase in size, they can obstruct and degrade the performance of antennas due to structural issues, particularly in electronic devices where the antenna is integrated, leading to signal loss and blocking phenomena.

Innovation Solution

The integration of antenna elements into the edge display areas of a flexible display panel, utilizing a curved surface design and embedding or attaching antenna layers within the display structure, allowing for improved signal transmission and reception without degrading performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the display apparatus increases in size, then the display area is improved, but signal loss and blocking phenomena worsen due to antenna structural problems

Engineering Contradiction:
Improvedisplay areaVSAvoidsignal transmission quality
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The patent transitions the antenna from a planar configuration to a three-dimensional curved surface configuration. The antenna element is formed on the curved surface of the flexible display panel, utilizing the vertical and lateral dimensions of the curve to create a spatially distributed antenna structure that maintains signal integrity across larger display areas.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent applies different structural characteristics to different regions of the antenna. The antenna element is strategically positioned and shaped along the curved surface to optimize signal transmission in specific directions, with varying density and configuration of antenna segments to address local signal blocking issues in different areas of the display apparatus.

Inventive Principle:
Principle #3Local quality

2Device complexity

If antenna elements are integrated into the display structure, then device complexity is reduced, but manufacturing precision requirements increase

Engineering Contradiction:
Improveantenna integration complexityVSAvoidantenna element placement precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent merges the antenna element with the flexible display panel structure itself. The antenna is formed as part of the display panel's curved surface, eliminating the need for separate antenna assemblies and reducing overall device complexity while maintaining integration benefits.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent utilizes the inherent curvature of the flexible display panel to define the antenna element's geometry. The curved surface provides a natural form for the antenna, where the panel's bending and shaping during manufacturing simultaneously creates both the display form factor and the antenna radiation pattern, reducing the need for additional precision machining or assembly steps.

Inventive Principle:
Principle #14Spheroidality (Curvature)
