Display Panel Opening Layout for Emission Line Bypass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels face challenges in increasing their functional capabilities while maintaining a larger display area, as existing technologies struggle to efficiently utilize the space by integrating additional components within the display area without compromising image display functionality.
Innovation Solution
A display panel design featuring a substrate with spaced openings, where a conductive layer connects emission control lines across these openings, allowing for the integration of components like sensors or cameras within the display area without interfering with the pixel circuits, and using a bottom metal layer made of molybdenum to enhance electrical connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If emission control lines are extended across the entire display area to control all pixels, then complete emission control is achieved, but signal interference and electrical connectivity issues occur when components are placed in the display area
Solution Approach 1:
The emission control lines are segmented into multiple sections by the openings, with each section independently controlling pixels in its region. This segmentation allows the lines to bypass component areas through the openings while maintaining emission control functionality, thereby reducing signal interference without compromising control reliability.
Solution Approach 2:
The openings act as intermediaries that allow emission control lines to pass through the display area without directly connecting across the entire area. This intermediary structure enables the lines to reach pixels on both sides of the openings while avoiding direct electrical pathways that would cause signal interference with components.
2Area of stationary object
If the display area is increased to occupy most of the panel area, then display functionality is improved, but space for additional components is reduced
Solution Approach 1:
The openings serve multiple functions: they allow passage of emission control lines, provide space for additional components, and maintain display area continuity. This multi-functionality enables the display panel to both maximize display area and integrate components without compromising either function.
Solution Approach 2:
The openings create vertical dimension opportunities by allowing components to be positioned beneath the display surface while maintaining visual display continuity. This dimensional approach enables component integration without reducing the effective display area.
3Adaptability or versatility
If openings are introduced in the display area to allow emission control lines to bypass, then component integration is enabled, but display area is reduced
Solution Approach 1:
The openings are strategically positioned in specific local areas where components need to be integrated, rather than uniformly distributed. This localized approach minimizes the impact on overall display area while providing necessary access points for emission control lines and component placement.
