Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light emitting apparatuses, such as OLED display devices, face challenges in achieving high resolution and luminance due to limitations in their fabrication processes.
Innovation Solution
A light emitting apparatus is designed with a substrate divided into two portions, where first and second light emitting elements are formed on each portion, and the second substrate portion is arranged parallel to the first, with light emitting directions aligned to enhance luminance and resolution by crossing each other vertically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If light emitting elements are arranged in a single layer on one substrate, then the fabrication process is simple, but the resolution and luminance are limited
Solution Approach 1:
The substrate is divided into two separate substrates (first substrate and second substrate), each carrying its own layer of light emitting elements. This segmentation allows independent fabrication of each layer with standard processes, while achieving doubled resolution when the layers are stacked and aligned in final assembly.
2Manufacturing precision
If light emitting elements are arranged to cross vertically on the same substrate, then resolution increases, but the light emitting directions become inconsistent
Solution Approach 1:
Instead of arranging light emitting elements in a crossed pattern on the same plane (2D arrangement), the invention moves to a three-dimensional configuration by placing elements on two separate substrates that face each other. This allows all elements to emit light in the same unified direction while achieving crossed-grid resolution through spatial separation.
3Manufacturing precision
If more light emitting elements are packed in the same area, then resolution increases, but the fabrication difficulty increases
Solution Approach 1:
The high-density light emitting element array is segmented into two separate layers on different substrates. Each layer can be fabricated using conventional processes at manageable density, and the overall high resolution is achieved through the combined stacked structure, avoiding the need to fabricate an extremely dense single layer.
