Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Naked-eye 3D technology in OLED display panels is limited by small information, small 3D viewing angle, and low pixel density, which restricts its application.
Innovation Solution
An array substrate with sub-pixels arranged in an alternating first and second composite region, featuring disconnected composite electrodes and an organic light-emitting layer, along with a lens array layer to project different images to the eyes, enhancing pixel density and 3D viewing angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional pixel electrode structure is used in OLED display panel, then manufacturing process is simple, but pixel density is low
Solution Approach 1:
The pixel electrode is divided into multiple composite electrodes (first composite electrode and second composite electrode) that are disconnected from each other. Each composite electrode corresponds to a different composite region within the sub-pixel, enabling independent control and higher pixel density while maintaining manufacturing feasibility through sequential formation processes
2Adaptability or versatility
If conventional sub-pixel structure is used, then device complexity is low, but 3D viewing angle is small
Solution Approach 1:
The sub-pixel is divided into multiple composite regions (first and second composite regions) arranged in different spatial positions. Each composite region contains disconnected composite electrodes that emit light in different directions, thereby expanding the 3D viewing angle by utilizing spatial dimensionality rather than simply increasing electrode density in a single plane
3Loss of information
If simple display structure is used, then manufacturing is easy, but information content is small
Solution Approach 1:
Each sub-pixel is segmented into multiple composite regions with disconnected composite electrodes, where each electrode-composite region pair can independently display different image information. This segmentation enables multiple views or enhanced information content within a single sub-pixel area without requiring a proportional increase in overall device complexity
Solution Approach 2:
The composite electrode structure serves multiple functions: it acts as both an electrode for electrical connection and as a light-emitting element with directional control. The disconnected composite electrodes within each sub-pixel can simultaneously display different information for different viewing angles or applications, increasing information content while maintaining structural efficiency
