Light-transmissive wires for camera integration in display devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in integrating additional electronic components such as cameras or sensors without compromising the display area, as existing designs often require bending or folding non-display areas, which can affect the structural integrity and functionality of the device.
Innovation Solution
A display device design that includes a substrate with pixels surrounding a first area for additional electronic components, featuring light-transmissive wires connecting scan lines, data lines, or driving voltage lines, and an encapsulation member with inorganic and organic insulating layers, allowing for increased transmissivity and reduced resistance while accommodating electronic components like cameras or sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional electronic components are integrated into the display area, then device functionality is enhanced, but display quality and structural integrity deteriorate
Solution Approach 1:
The display area is segmented into a first area for electronic components and a second area for pixel arrays. This spatial segmentation allows electronic components to be integrated without interfering with the pixel arrangement and light emission in the second area, thereby maintaining display quality while enhancing device functionality.
Solution Approach 2:
Electronic components are positioned in a first area that is vertically or spatially separated from the pixel array plane. This dimensional separation allows components to coexist with the display structure without compromising the two-dimensional pixel layout, resolving the contradiction between integration and display quality.
2Adaptability or versatility
If non-display areas are bent or folded to accommodate components, then component integration is achieved, but structural integrity deteriorates
Solution Approach 1:
The substrate is divided into distinct functional areas: a first area for electronic components and a second area for pixel arrays. This segmentation eliminates the need to bend or fold non-display areas, as components are accommodated in a dedicated spatial zone, thereby preserving the overall structural integrity of the display device.
3Reliability
If wires are made thicker to reduce resistance, then electrical connection quality improves, but light transmissivity deteriorates
Solution Approach 1:
The electrical parameters of the wires are optimized by adjusting conductivity through material selection and cross-sectional area configuration. This allows the wires to achieve low resistance for reliable electrical connections while maintaining sufficient light transmissivity by balancing thickness and material properties.
Solution Approach 2:
Light-transmissive wires are constructed using composite materials that combine electrical conductivity with optical transparency. This enables the wires to simultaneously achieve low resistance for reliable electrical connections and high light transmissivity for maintaining display quality.
