Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in efficiently integrating sensors and other components within the display area, particularly in terms of design flexibility and light transmittance variations across different display areas.
Innovation Solution
A display apparatus is designed with a substrate that includes multiple display areas, each with specific pixel arrangements and transmission areas. The apparatus features a unique arrangement of pixel electrodes and opposite electrodes, with different planar areas and connections, allowing for varied light transmittance and component integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensors and components are integrated within the display area, then device functionality is enhanced, but light transmittance is reduced
Solution Approach 1:
The display area is divided into multiple display areas (first, second, third display areas) with different pixel arrangements and transmission characteristics. This segmentation allows different regions to serve different functions - some optimized for display, others for sensor integration with higher transmittance requirements.
Solution Approach 2:
Different display areas are designed with different properties: the first display area has lower resolution with larger transmission areas for sensor integration, while the second and third display areas have higher resolution for primary display functions. This local differentiation optimizes both component integration and light transmittance in respective regions.
2Adaptability or versatility
If multiple display areas with different resolutions are created, then design flexibility is improved, but manufacturing complexity increases
Solution Approach 1:
The display panel is segmented into multiple display areas with different resolutions and functions. The first display area uses a lower resolution grid while the second and third areas use higher resolution grids, allowing flexible design for different application requirements.
Solution Approach 2:
The opposite electrodes are designed to serve multiple functions: they act as both display electrodes in high-resolution areas and as transmission regions in lower-resolution areas. This multi-functionality reduces the need for separate component layers, simplifying manufacturing despite the complex multi-area design.
3Illumination intensity
If opposite electrodes with different planar areas are used, then light transmittance control is improved, but electrode complexity increases
Solution Approach 1:
The opposite electrodes are designed with different planar areas matched to their specific display area requirements. The first opposite electrode has a smaller area corresponding to the lower resolution first display area, while the second and third opposite electrodes have larger areas for their respective high-resolution areas. This local optimization controls light transmittance effectively.
Solution Approach 2:
The opposite electrodes are merged into a single continuous layer that spans across all display areas, with varying planar dimensions in different regions. This unified electrode structure simplifies manufacturing compared to using separate electrode layers for each display area, while still achieving the desired light transmittance control through local area variation.
