Display Panel Data Line Layout Around Camera Cutout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The presence of functional devices such as front cameras and sensors in display apparatuses necessitates cut-out areas, which require additional wiring space, reducing the screen-to-body ratio and affecting display uniformity.
Innovation Solution
The implementation of data connection lines that electrically connect divided data segments around the functional device area, reducing the number of lines within the functional area and increasing the display area, while maintaining display uniformity through symmetrical and non-intersecting data connection line arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data lines are divided by the cut out area and connected by connection lines around the cut out area, then the functional devices can be properly connected, but the wiring space increases and the screen-to-body ratio decreases
Solution Approach 1:
The patent changes the arrangement dimension of data connection lines from the horizontal plane (around the cutout) to the vertical dimension (through overlapping regions). Data connection lines are arranged to extend from the first substrate through the second substrate, utilizing the thickness dimension to reduce the horizontal wiring space and increase the screen-to-body ratio while maintaining connection reliability.
Solution Approach 2:
The patent implements a nested structure where data connection lines are embedded within overlapping regions of the first and second substrates. The connection lines are positioned within the thickness of the substrates, creating a compact nested arrangement that minimizes the external footprint and maximizes the display area.
2Reliability
If connection lines are arranged around the cut out area, then data segments can be connected, but the display uniformity deteriorates due to irregular wiring distribution
Solution Approach 1:
The patent employs asymmetric arrangement strategies where data connection lines are positioned at different distances from the cutout boundary depending on their function. Some connection lines are arranged closer to the center while others are positioned toward the edges, creating an asymmetric distribution that optimizes both electrical connection and display uniformity by avoiding concentrated wiring in any single region.
Solution Approach 2:
The patent applies different arrangement strategies to different data connection lines based on their specific functions and positions. Connection lines carrying different signals or serving different pixel regions are arranged with different spacing and orientations, optimizing the local wiring quality in each region while maintaining overall display uniformity.
