Antenna Conductor Layer on Display Back for Wireless Thinning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with wireless communication functions face challenges in achieving a lighter and thinner design due to the space requirements of multiple antennas needed for various communication standards, particularly in devices with large displays where antenna design is limited by display size and must avoid metal components and other electronic elements.
Innovation Solution
The electronic device incorporates a conductor layer on the back of the display screen as the antenna, allowing for the reuse of spacing areas, such as around the camera, to emit and receive radio frequency signals without occupying circuit board space, thereby supporting multiple communication standards and facilitating a lighter and thinner design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antennas are directly disposed on the circuit board, then wireless communication functions are achieved, but the device weight and thickness increase
Solution Approach 1:
The patent merges the antenna structure with the display screen by disposing the antenna on the spacing area of the display screen back surface. This integration eliminates the need for separate antenna components on the circuit board, reducing overall device weight while maintaining wireless communication functionality.
Solution Approach 2:
The display screen back surface serves multiple functions: it provides structural support, housing for camera modules, and a mounting surface for the antenna. This multi-functionality reduces the need for additional components and contributes to weight reduction.
2Adaptability or versatility
If multiple antennas are added for various communication standards, then communication versatility improves, but the device becomes heavier and thicker
Solution Approach 1:
The patent transitions from a planar circuit board layout to a three-dimensional utilization of the display screen back surface. By disposing the antenna on the spacing area (a different spatial dimension), the design accommodates multiple antennas without increasing device thickness.
Solution Approach 2:
The antenna system is segmented into multiple independent antenna elements disposed on different areas of the display screen back surface. This segmentation allows each antenna to serve specific communication standards while maintaining a compact overall structure.
3Area of stationary object
If display screen size is increased, then user experience improves, but antenna design space is reduced
Solution Approach 1:
The patent applies local quality by utilizing the spacing area (a specific local region) on the display screen back surface for antenna disposal. This approach allows the majority of the display screen to maintain its large size for user experience while the local spacing area provides the necessary space for antenna design and wireless communication functionality.
