Light Emitting Panel Orientation Mark via Shared Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light emitting panels with electro luminescence elements on substrates face difficulties in identifying the emitting surface, leading to poor workability during manufacturing and attachment to other units.
Innovation Solution
Incorporating a visible mark made of the same material as the metal wiring on the glass substrate, which is asymmetric and visible from both surfaces, to distinguish the emitting and non-emitting surfaces, allowing workers to correctly orient the panel without increasing processes or costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a light emitting element is provided on a substrate without any marking, then the manufacturing process is simple and costs are low, but it becomes difficult to identify the emitting surface and workability during attachment is poor
Solution Approach 1:
A mark is formed on the substrate that is visible from both the front and rear surfaces, allowing workers to easily identify the emitting surface orientation during handling and attachment operations
Solution Approach 2:
The mark serves as an intermediary visual indicator between the substrate and the worker, providing orientation information without affecting the light emitting function of the element
2Ease of operation
If a mark is added to indicate the emitting surface, then workability during attachment improves, but the manufacturing process becomes more complex and costs increase
Solution Approach 1:
The mark is formed using the same material and process as the metal wiring, combining the orientation indication function with the existing electrical connection structure, thereby avoiding additional manufacturing steps
Solution Approach 2:
The mark serves multiple functions: it indicates the emitting surface orientation, is formed using the same material as the wiring, and can be created during the existing metal wiring formation process

AI summary
In general, according to the embodiment, a light emitting panel includes a glass substrate, a light emitting element, metal wiring, and a mark. The glass substrate allows light to pass through. The light emitting element is present in any one of a first plane and a second plane which is a rear surface of the first plane, of the glass substrate. The metal wiring is present on one surface, and applies voltage to the light emitting element. The mark is present on one surface, and is formed of the same material as the metal wiring.
