Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display and antenna arrangements for wireless communication terminals face challenges in providing both high-quality optical representation and effective radio communication capabilities, particularly in advanced systems where space is limited, and antenna elements cannot be arranged freely or flexibly to optimize data transmission and multipath channel coverage.
Innovation Solution
A display and antenna arrangement where the electrically conductive layer is perforated with densely arranged holes filled with dielectric material, allowing for flexible placement of antenna elements on the front of the display screen without impairing optical representation, enabling efficient radio communication in all directions and high spatial and polarimetric resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If antenna elements are placed on the frame surrounding the display, then antenna functionality is provided, but the display screen area is reduced and antenna arrangement flexibility is limited
Solution Approach 1:
The patent combines the display screen and antenna elements into a single integrated structure. The antenna elements are formed directly on the front surface of the display screen using a conductive layer, merging two previously separate functions (display and communication) into one component. This eliminates the need for separate frame-based antenna structures and enables flexible antenna element placement without compromising display area.
2Area of stationary object
If antenna elements are placed on the back side of the display, then display area is maximized, but radio communication capability is screened and attenuated
Solution Approach 1:
Instead of placing antenna elements on the back side of the display (conventional approach), the patent inverts the arrangement by positioning the antenna elements on the front surface of the display screen. This inversion allows the antenna elements to radiate and receive radio waves without being screened by the display structure, while still maintaining full display area. The conductive layer is positioned such that it does not interfere with the display's optical properties.
3Productivity
If multiple antenna elements are arranged freely for optimal communication coverage, then data transmission capacity is maximized, but the device size increases
Solution Approach 1:
The display screen serves multiple functions: it displays visual information and simultaneously acts as the substrate for antenna elements. The front surface of the display screen is used both for optical output and for housing the conductive layer that forms the antenna elements. This multi-functionality allows multiple antenna elements to be arranged on the display surface without requiring additional device space, as the display area itself is being utilized for both purposes.
4Reliability
If a conductive layer is placed on the display screen for antenna elements, then radio communication is enabled, but optical representation quality may be affected
Solution Approach 1:
The conductive layer is designed with spatially varying properties: in regions where antenna elements are needed, the conductive material is present to provide radio communication functionality, while in regions corresponding to display pixels, the conductive layer is configured to be transparent or non-interfering. This local differentiation allows the same conductive layer to serve both antenna and display functions without compromising either performance. The pattern and density of the conductive material are optimized locally to balance electrical and optical requirements.
