Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in integrating additional functions while maintaining thinness and lightness, particularly in creating a transmission region that allows for the inclusion of components like cameras or sensors without compromising the display area's functionality.
Innovation Solution
A display device structure featuring a substrate with a sealing member, a transparent material layer, and a light-shielding portion on an encapsulation substrate, where the transparent material layer is directly contacted with the encapsulation substrate and includes a convex surface, enhancing light transmissivity and impact resistance by surrounding the transmission area with a sealing member and light-shielding portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transmission region is formed on the display area to integrate additional functions like cameras or sensors, then the versatility and functionality of the display device are enhanced, but the display area is reduced and light transmissivity may be compromised
Solution Approach 1:
The display area is segmented into a first area (display region) and a second area (transmission region). The first area maintains display functionality with pixels, while the second area is configured for light transmission to accommodate additional functions such as cameras or sensors. This spatial segmentation allows both display and additional functions to coexist without compromising each other's performance.
Solution Approach 2:
Different regions of the display device are assigned different functional qualities. The first area is optimized for display with appropriate pixel structures and light-emitting characteristics, while the second area is optimized for light transmission with transparent or translucent materials and minimal obstruction. This local differentiation enables each region to perform its specific function effectively.
2Adaptability or versatility
If a transmission region is formed on the display area to integrate additional functions, then the versatility of the display device is enhanced, but the light transmissivity and impact resistance of the display area may be compromised
Solution Approach 1:
The display device is divided into a first area for display and a second area for light transmission. This segmentation allows the second area to be specifically designed with materials and structures optimized for high light transmissivity and impact resistance, while the first area maintains its display functionality. The sealing member further segments the internal structure to protect different regions appropriately.
Solution Approach 2:
A sealing member is provided to surround at least a portion of the second area (transmission region). This sealing structure serves as a protective barrier that enhances impact resistance by distributing and absorbing external forces before they can damage the underlying components. The sealing member is configured to withstand impacts while maintaining the structural integrity of the transmission region, thereby beforehand cushioning against potential damage.
3Weight of moving object
If the display device is made thinner and lighter for wider application ranges, then the portability and versatility are improved, but the structural integrity and protection of internal components may be compromised
Solution Approach 1:
The display device employs thin-film structures and flexible sealing members that provide adequate structural protection while maintaining a thin and light profile. The sealing member, though thin, is designed with appropriate material properties and geometric configuration to provide sufficient strength and protection for internal components without adding significant weight or thickness.
Solution Approach 2:
The sealing member is positioned to surround and protect internal components before external impacts can reach them. This protective structure is designed to absorb and distribute impact forces, providing beforehand cushioning that protects the delicate internal components of the thin display device without requiring thick protective housings that would increase weight and thickness.
