Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices face challenges in designing multi-functional and high-resolution displays with through portions, which can degrade image quality and increase manufacturing complexity due to disconnections in data lines and scan lines across different display regions with varying resolutions.
Innovation Solution
A display apparatus with a substrate and display unit featuring through portions, where data lines are connected through connection lines to maintain signal integrity across regions with different resolutions, and a thin film encapsulation layer with organic and inorganic layers to enhance durability and reduce non-display areas, allowing for efficient manufacturing and improved image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If through portions are added to enable multi-functionality (e.g., cameras, sensors), then the versatility of the display device is improved, but the manufacturing complexity increases due to disconnections in data lines and scan lines
Solution Approach 1:
Connection lines are introduced as intermediary elements to bridge the discontinuity caused by through portions. These connection lines electrically connect data lines and scan lines that would otherwise be disconnected by the through portions, enabling signal transmission across multiple display regions with different resolutions while maintaining manufacturing feasibility
Solution Approach 2:
The display region is divided into multiple regions (first display region and second display region) with different resolutions, allowing each region to be optimized for specific functions. This segmentation enables through portions to be strategically placed in non-critical areas while maintaining high resolution in critical display areas
2Area of stationary object
If through portions are introduced to reduce non-display areas, then the display area efficiency is improved, but image quality degrades due to signal disconnections
Solution Approach 1:
Connection lines serve as mediators to restore signal continuity across through portions. By introducing these intermediary conductive paths, the patent ensures that data signals and scan signals can traverse through regions with through portions without degradation, maintaining image quality while maximizing display area
Solution Approach 2:
Different display regions are assigned different resolutions and functions. The first display region maintains high resolution for critical display areas, while the second display region can have lower resolution where through portions are located, optimizing overall image quality while maximizing usable display area
3Ease of manufacture
If data lines are disconnected at through portions to simplify manufacturing, then the ease of manufacture is improved, but signal integrity is lost across display regions
Solution Approach 1:
Connection lines are introduced as intermediary elements to bridge the discontinuity caused by through portions. These connection lines electrically connect data lines and scan lines that would otherwise be disconnected by the through portions, enabling signal transmission across multiple display regions with different resolutions while maintaining manufacturing feasibility
