Solution Overview
Problem
Display devices face challenges in efficiently utilizing display areas, particularly when electronic components are integrated, as existing technologies struggle to provide effective image display and functionality in regions where components are arranged, leading to limitations in design flexibility and functionality.
Innovation Solution
A display panel design that includes a main display area and a component area, with a second display panel underneath, allowing for image display even in areas with electronic components, using inorganic light-emitting diodes and a movement driver to adjust the display panels relative to the components, and employing pixel electrodes with reflective and transparent layers for enhanced light emission and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a component area is designated for electronic components, then component functionality is improved, but display capability in that region deteriorates
Solution Approach 1:
The component area is designed to serve dual purposes: it houses electronic components (camera, sensor, flash) while simultaneously functioning as a display region through the second display panel. This multi-functional design allows the same physical space to fulfill both component integration and image display requirements, resolving the contradiction between component functionality and display capability.
Solution Approach 2:
The second display panel is positioned underneath the first display panel and overlaps with the component area, creating a nested structure. The component is arranged below the first display panel, and the second display panel is arranged below the first display panel, with the component overlapping the component area. This nested arrangement enables the component area to contain multiple functional layers including both electronic components and display elements.
2Area of stationary object
If a second display panel is added underneath, then display area utilization is improved, but device complexity increases
Solution Approach 1:
The first display panel and second display panel are merged into a stacked configuration where both panels share the same physical footprint. The component area includes regions where both display panels are arranged, allowing efficient utilization of the display area without requiring additional lateral space. This combining approach maximizes display area utilization while controlling device complexity through vertical integration.
3Illumination intensity
If pixel electrodes with reflective layers are used, then light emission is improved, but light transmission deteriorates
Solution Approach 1:
Different pixel electrode configurations are applied to different regions within the component area based on functional requirements. First auxiliary display elements use pixel electrodes with reflective layers for enhanced light emission, while second auxiliary display elements use pixel electrodes without reflective layers for better light transmission. This local differentiation resolves the contradiction by optimizing each sub-region for its specific display needs.
