Under-Display Pixel Layout for Camera Integration and Transmittance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices often feature black holes where components like cameras are positioned, leading to reduced transmittance and visibility issues due to the absence of pixels and wires in these regions.
Innovation Solution
A display device design with varying pixel and wire densities in different regions, allowing for components like cameras to be integrated while maintaining high luminance and transmittance by adjusting the number of pixels and wires per unit area in specific regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pixels and wires are densely arranged in all regions, then display quality is improved, but components like cameras cannot be integrated
Solution Approach 1:
The patent applies local quality by differentiating pixel density across different regions of the display device. In regions where components like cameras are located, pixel density is reduced to accommodate these components, while maintaining higher pixel density in regions where display functionality is prioritized. This allows the display device to integrate multiple components without sacrificing overall display quality.
2Adaptability or versatility
If pixels are removed from certain regions to accommodate components, then component integration is enabled, but transmittance and luminance are reduced
Solution Approach 1:
The patent employs parameter changes by adjusting the density of pixels and wires as a variable parameter across different regions. By changing the spatial distribution density of pixels and wires, the system optimizes the balance between component integration and display performance, ensuring that regions with components still maintain adequate transmittance and luminance for functional operation.
3Reliability
If wire density is increased to maintain signal transmission, then display functionality is improved, but transmittance is reduced due to more wire material
Solution Approach 1:
The patent applies local quality by varying wire density according to the functional requirements of different regions. In regions with fewer pixels (where components are located), wire density is correspondingly reduced to minimize material usage and maintain transmittance, while still providing sufficient signal transmission capability for the reduced number of pixels and integrated components.
