Display Substrate Camera Integration via Signal Line Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of camera devices in display devices often occupies frame positions, hindering the achievement of full screen and narrow frame designs, especially when cameras are integrated into the display region.
Innovation Solution
A display substrate design that includes a base substrate with specific opening regions, inter-opening regions, and a display region, where signal lines are configured to pass through these regions, allowing for the integration of camera devices while maximizing the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If camera devices are installed on the side outside the display region, then the camera device can be properly positioned, but the frame position is occupied which prevents full screen and narrow frame design
Solution Approach 1:
The patent applies dimensionality change by moving the camera device from a lateral position (outside the display region) to a vertical integration within the display region. The camera is positioned in the inter-opening region between first and second openings, utilizing the vertical space within the display area to achieve narrow frame design while maintaining camera functionality.
Solution Approach 2:
The patent implements nesting by integrating the camera device within the display region structure. The camera is nested in the inter-opening region, which is itself nested within the overall display device structure, allowing the camera to occupy space that would otherwise be part of the display area without compromising the display region.
2Area of stationary object
If camera devices are integrated into the display region, then full screen and narrow frame design is achieved, but display quality consistency may be affected
Solution Approach 1:
The patent applies local quality by creating distinct functional zones within the display region. The inter-opening region where the camera is integrated has different structural characteristics compared to other display areas. The display substrate includes specific opening peripheral regions and inter-opening regions with tailored designs to maintain display quality consistency while accommodating the camera integration.
Solution Approach 2:
The patent segments the display region into multiple functional zones including first opening regions, second opening regions, and inter-opening regions. This segmentation allows different areas to serve different purposes - the opening regions for display functions and the inter-opening region for camera integration - thereby maintaining overall display quality while enabling camera placement.
3Adaptability or versatility
If signal lines pass through opening peripheral regions and inter-opening regions, then camera integration is enabled, but signal line routing complexity increases
Solution Approach 1:
The patent applies universality by designing signal lines that serve multiple functions. The first signal line not only provides display signals to pixel circuits but also passes through the inter-opening region to enable camera integration. This multi-functional routing reduces the need for separate dedicated signal paths and simplifies the overall device structure despite the increased routing requirements.
