Display Panel Partition Structure for Vertical Light Emission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses face the challenge of emitted light being emitted in various directions, necessitating a viewing-angle control technology that effectively transmits light only in a vertical direction with respect to the display panel.
Innovation Solution
The display apparatus incorporates a display panel with partitions made of inorganic materials like molybdenum tantalum oxide (MoTaOx) and organic materials, along with auxiliary layers and stable layers, to filter and direct light emissions, ensuring that light is primarily emitted vertically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If partitions are made taller to block oblique light, then viewing angle control improves, but device complexity increases
Solution Approach 1:
The partition structure is divided into multiple segments: first partitions extending from the display panel, second partitions extending from the first auxiliary layer, and third partitions extending from the second auxiliary layer. Each segment has a specific height and positioning that contributes to the overall light filtering function, allowing progressive blocking of oblique light without requiring a single excessively tall partition.
Solution Approach 2:
The partition structure extends in the vertical dimension with multiple layers at different heights. The first partitions have a first height, second partitions have a second height greater than the first, and third partitions have a third height greater than the second, creating a stepped configuration that enhances light blocking capability through vertical dimensionality.
2Reliability
If multiple auxiliary layers and partitions are added to control light direction, then light filtering effectiveness improves, but manufacturing complexity increases
Solution Approach 1:
The first auxiliary layer is formed to cover the display panel and first partitions before the second partitions are formed. The second auxiliary layer is then formed to cover the second partitions and display panel before the third partitions are formed. This sequential formation process establishes a stable foundation for each subsequent layer, ensuring proper alignment and reducing manufacturing complexity.
Solution Approach 2:
The partition structure employs a nested configuration where second partitions are formed on the first auxiliary layer that already covers the first partitions, and third partitions are formed on the second auxiliary layer that covers the second partitions. Each layer is nested within and supported by the previous layers, creating a compact integrated structure.
