Display Voltage Pattern Layout for Static and Noise Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices are susceptible to static electricity and noise signals from the outside, which can lead to seam generation in insulating layers and potential short circuits or burning between wires.
Innovation Solution
The display device incorporates specific patterns and wires in the non-display area that block or reduce external static electricity and noise signals by alternating voltage patterns and extension wires, ensuring they are connected and formed with the same material or spaced apart, with alignment keys and auxiliary wires to enhance connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voltage patterns and extension wires are disposed in the non-display area to block static electricity and noise signals, then the reliability of the display device is improved, but the device complexity increases due to additional patterns and wires
Solution Approach 1:
The voltage patterns are segmented into multiple alternating patterns (first voltage pattern, second voltage pattern, first sub-voltage pattern, second sub-voltage pattern) disposed at different locations in the non-display area. This segmentation allows each pattern to independently contribute to noise blocking while distributing the complexity across multiple simple elements rather than one complex structure
Solution Approach 2:
The extension wires serve multiple functions: they electrically connect the voltage patterns to each other, extends the noise-blocking functionality across different sides of the non-display area, and provide structural support for the insulating layers. This multi-functionality reduces the need for separate components, thereby improving reliability without proportionally increasing complexity
2Manufacturing precision
If extension wires are formed integrally with voltage patterns using the same material, then manufacturing precision is improved, but the ease of manufacture decreases due to stricter material and connectivity requirements
Solution Approach 1:
The extension wires are merged with the voltage patterns as integral structures formed from the same conductive material. This merging eliminates the need for separate connection processes between patterns and wires, ensuring perfect electrical contact and alignment. The integrated formation improves manufacturing precision by reducing interface defects while the use of standard conductive materials maintains ease of manufacture
