Display Antenna Sheet Layout for Thin Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As mobile electronic devices become thinner, there is less available space for antennas, making it challenging to integrate wireless communication components within the device without compromising display area or increasing thickness.
Innovation Solution
A display device design that incorporates an antenna sheet between the display panel and the window, featuring a mesh-shaped portion for the display area and a frame-shaped portion for the non-display area, allowing for efficient wireless signal transmission while maintaining a slim profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the device is made thinner to reduce overall thickness, then the aesthetic appeal and portability are improved, but the available space for antenna installation is reduced
Solution Approach 1:
The patent combines the antenna structure with the display assembly by integrating the antenna into the space between the display panel and the window, merging two previously separate functional components (display and wireless communication) into a unified structure that eliminates the need for separate antenna compartments
Solution Approach 2:
The patent transitions the antenna from a traditional external or side-mounted three-dimensional structure to a two-dimensional planar configuration that lies flat within the display assembly layers, effectively utilizing the surface area between components rather than requiring additional vertical or lateral space
2Reliability
If external antennas are used to ensure reliable wireless communication, then the communication reliability is improved, but the device structure becomes more complex and thickness increases
Solution Approach 1:
The patent merges the antenna function with the existing display assembly structure, eliminating the need for separate external antenna components and their associated mounting structures, thereby reducing overall device complexity while maintaining wireless communication functionality
Solution Approach 2:
The display assembly structure serves itself by incorporating the antenna function within its own layers, allowing the display assembly to provide both visual display and wireless communication capabilities without requiring additional dedicated components or structures

AI summary
A display device includes a display panel having a display area, in which an image is displayed, and a non-display area, in which no image is displayed. A window overlaps the display panel. An antenna sheet is disposed between the display panel and the window. The antenna sheet includes a first antenna portion having a mesh shape, and a second antenna portion integrally connected to the first antenna portion and having a frame shape. The first antenna portion corresponds to the display area and the second antenna portion corresponds to the non-display area.
