Display Panel Signal Shielding Frame for Antenna Directivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels face challenges in signal directivity and interference due to the independent placement of antennas, which require significant space and result in signal loss and interference outside the intended target region.
Innovation Solution
A display panel design incorporating a signal shielding frame between two substrates, where antennas are placed within the shielding frame to allow only outward signal transmission, enhancing directivity and reducing interference by shielding inward signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If antenna portions are placed independently outside the display module, then sufficient space is reserved for antenna placement, but the device complexity and space requirements increase
Solution Approach 1:
The patent integrates the antenna portions directly into the display panel structure by forming conductive patterns on the same substrate as the display electrodes. The antenna conductors are merged with the display electrode structures, eliminating the need for separate external antenna modules and reducing overall device complexity while maintaining adequate signal transmission space.
2Adaptability or versatility
If antenna portions are located at the top of the display panel, then signal transmission coverage is maximized in 360 degrees, but signal directivity is restricted and interference increases
Solution Approach 1:
The patent implements directional signal transmission by configuring the antenna conductors to transmit signals preferentially in specific directions. The conductive patterns are designed with asymmetric geometries and positioning that create localized signal transmission zones, allowing the display panel to transmit signals directionally toward the user while minimizing omnidirectional radiation and associated interference.
3Device complexity
If antenna portions are integrated within the display panel, then device complexity is reduced, but signal transmission directivity and interference control become challenging
Solution Approach 1:
The patent divides the antenna functionality into segmented conductive patterns that are distributed across different regions of the display panel. Each segment can be independently controlled or optimized for specific directional transmission requirements. This segmentation allows precise control over signal directivity while maintaining integration within the display structure, resolving the conflict between simplified device complexity and manufacturing precision for signal control.
