Display Panel Antenna Wiring Layout for Narrow Mobile Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels have a relatively wide side-frame due to the need for large-width signal wirings of electromagnetic antenna coils, which compromises the design and functionality of mobile terminals.
Innovation Solution
The display panel design incorporates electromagnetic antennas with at least a portion of the coil and wirings located within the display area, allowing the wirings to be arranged in a way that reduces their length and distribution, thereby minimizing the need for wide side-frames by avoiding their placement in the non-display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signal wirings of electromagnetic antenna coil are arranged in the non-display area, then the circuit impedance can be ensured, but the side-frame becomes relatively wide
Solution Approach 1:
The patent transitions the wiring arrangement from the non-display area (peripheral dimension) to the display area (central dimension), utilizing the space within the display region to route wirings. This dimensional shift allows wirings to be positioned without contributing to side-frame width, thereby resolving the contradiction between maintaining circuit impedance and reducing side-frame width.
Solution Approach 2:
Instead of placing wirings in the conventional non-display area as done in prior art, the patent inverts the arrangement by positioning at least a portion of the wirings within the display area. This inverted approach eliminates the need for wide side-frames while maintaining the necessary circuit impedance through alternative routing paths.
2Reliability
If signal wirings have relatively large width to ensure circuit impedance, then the electromagnetic antenna function is maintained, but the display panel occupies more area
Solution Approach 1:
The patent applies local quality by positioning wirings specifically within the display area where they are needed for electromagnetic antenna functionality, rather than uniformly distributing them across the entire panel. This localized arrangement optimizes space utilization and reduces the overall area occupied by the display panel while maintaining necessary circuit impedance.

AI summary
The application discloses a display panel and a mobile terminal. The display panel arranges at least a portion of coil of an electromagnetic antenna in a display area, and wirings of the electromagnetic antenna are arranged in the display area, rather than being arranged in a non-display area similar to a known display device, so that wirings in the non-display area can be avoided to realize a narrow side-frame structure of a mobile terminal.
