Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of arranging antennas within the limited space of display panels in electronic devices, such as smartphones, is exacerbated by increasing demands for larger screens and improved wireless performance, which complicates the integration of antennas without increasing the device's size.
Innovation Solution
The display panel incorporates antenna modules within the line winding areas of the non-display region, utilizing the space typically occupied by signal lines, thereby reducing the need for additional space and minimizing the non-display area, thus enhancing the screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antenna modules are arranged within the display panel, then wireless performance is improved, but the limited internal space makes arrangement difficult
Solution Approach 1:
The patent utilizes the non-display area as a third spatial dimension for antenna arrangement, moving away from traditional display-area-constrained layouts. By projecting antenna modules into the non-display region, the solution creates additional available space without increasing the overall device footprint, effectively resolving the space constraint while maintaining wireless performance requirements
Solution Approach 2:
The non-display area is assigned multiple functions: it serves both as the traditional signal line winding region and as the location for antenna module arrangement. This multi-functional utilization of the same spatial region allows the patent to accommodate antenna modules without requiring additional dedicated space, thereby resolving the contradiction between wireless performance and space limitation
2Reliability
If additional space is reserved for antenna modules, then wireless performance is improved, but the non-display area size increases
Solution Approach 1:
The patent merges the antenna module arrangement space with the existing non-display area, combining two previously separate functional regions into one unified space. The antenna modules are positioned within the non-display area boundaries, eliminating the need to expand the non-display region while still providing adequate space for antenna functionality
Solution Approach 2:
The solution repositions antenna modules from potential additional space requirements into the existing non-display dimensional space. By utilizing the vertical and lateral dimensions of the non-display area more efficiently, the patent accommodates antenna modules without increasing the overall non-display area footprint
3Area of stationary object
If antenna modules are placed in the non-display area, then the screen-to-body ratio is improved, but signal line winding space is reduced
Solution Approach 1:
The non-display area is segmented into distinct functional zones: one region dedicated to signal line winding and another region allocated for antenna modules. This segmentation allows both signal lines and antenna modules to coexist within the non-display area without excessive interference, maintaining adequate space for signal line functionality while achieving the screen-to-body ratio improvement
Solution Approach 2:
Different regions of the non-display area are assigned different functional qualities: areas closer to the display region are optimized for signal line winding, while areas further away are designated for antenna modules. This local differentiation ensures that signal line winding space is preserved in critical areas while allowing antenna placement in regions where signal interference is minimized
