Irregular Display Panel VDD Layout for Narrow Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for manufacturing full-screen mobile phone displays with irregular shapes face challenges in efficiently arranging signal lines, leading to increased space occupation and difficulty in achieving a narrow edge design due to complex wiring arrangements.
Innovation Solution
The solution involves arranging a single VDD wire in the irregular-shaped region, connected to pixels through multiple connection wires, which reduces current and voltage differences between regular and irregular-shaped regions, allowing for a more compact non-display region and a narrower edge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple VDD wires are arranged in the irregular-shaped region to ensure uniform current distribution, then brightness uniformity is improved, but the space occupied by signal lines increases and the edge becomes wider
Solution Approach 1:
The patent segments the VDD wire into multiple sections: a first VDD wire in the regular-shaped region and a second VDD wire in the irregular-shaped region. This segmentation allows each VDD wire to be optimized for its specific region, ensuring uniform current distribution while minimizing the total space occupied by signal lines.
Solution Approach 2:
The patent applies different VDD wire configurations to different regions: the first VDD wire serves the regular-shaped region while the second VDD wire serves the irregular-shaped region. This local quality approach ensures that each region receives appropriate current distribution without requiring excessive signal line space across the entire display.
2Reliability
If multiple VDD wires are arranged to reduce current and voltage differences, then display quality is improved, but the complexity of wire arrangement increases
Solution Approach 1:
The VDD wire is segmented into two distinct parts (first VDD wire and second VDD wire) that are arranged in different regions. This segmentation simplifies the overall arrangement by clearly defining the function and location of each wire segment, reducing the complexity of wire arrangement while maintaining display quality.
Solution Approach 2:
The patent extracts the VDD wire function into separate components for the regular-shaped region and irregular-shaped region. By taking out the VDD wire arrangement into distinct, region-specific components, the complexity of coordinating multiple wires across the entire display is reduced while still achieving the desired current and voltage uniformity.
3Area of stationary object
If a single VDD wire is used to minimize space occupation, then the edge becomes narrower, but current and voltage differences between regions increase
Solution Approach 1:
Instead of using a single VDD wire that would compromise uniformity, the patent segments the VDD supply into two wires positioned in different regions. This segmentation maintains narrow edges by limiting signal line space while ensuring current and voltage uniformity through strategic placement in the regular-shaped and irregular-shaped regions.
Solution Approach 2:
The patent implements local quality by providing dedicated VDD wire coverage for different regions: the first VDD wire serves the regular-shaped region while the second VDD wire serves the irregular-shaped region. This ensures that each region receives appropriate electrical characteristics without requiring a single complex wire arrangement that would increase space occupation.

AI summary
A display and a display panel are provided. An additional VDD wire is arranged in an irregular-shaped region. The VDD wire is connected to a pixel arranged in the irregular-shaped region through a plurality of connection wires, such that the display may have a narrow side edge, and at the same time, a difference between impedances of the irregular-shaped region and a regular-shaped display region may not be large, and a display region may not be split.
