Transparent Display Organic Layer Layout for Uniform Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent display apparatuses experience a significant difference in visibility between the display area and the non-display area due to the absence of a light emitting layer in the non-display area, leading to a noticeable contrast.
Innovation Solution
The transparent display apparatus includes a non-display area with extended organic layers and second transmissive portions, where the ratios of overlap between the organic layer and transmissive portions are varied to match the display area, reducing the visibility difference by providing similar structures and light transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light emitting layer is provided only in the display area, then light emission function is achieved in the display area, but a difference in visibility occurs between the display area and the non-display area
Solution Approach 1:
The patent applies local quality by providing the organic layer selectively in specific regions. The organic layer is provided in the display area and partially in the non-display area (bezel area), creating different local structures to achieve different functions: light emission in the display area and visibility matching in the bezel area, thereby resolving the visibility difference while maintaining the light emission function.
Solution Approach 2:
The patent segments the organic layer distribution into different regions: fully provided in the display area for light emission, and partially provided in the non-display area for visibility matching. This segmentation allows independent optimization of each region's properties without compromising the other.
2Manufacturing precision
If the organic layer is extended into the non-display area, then visibility difference is reduced, but the structure becomes more complex
Solution Approach 1:
The organic layer serves multiple functions: in the display area, it provides light emission; in the non-display area, it provides visibility matching. This multi-functionality reduces the need for separate structures, simplifying the overall device complexity while achieving both light emission and visibility uniformity.

AI summary
A transparent display apparatus is provided, which reduces a difference in visibility between a non-display area and a display area. The transparent display apparatus comprises a display area disposed on a substrate, including a plurality of pixels having a first transmissive portion, and a non-display area disposed near the display area on the substrate, having a plurality of second transmissive portions, wherein the non-display area further includes an organic layer provided to be extended from the display area, and ratios of the organic layer overlapped with the plurality of second transmissive portions in the non-display area are different from each other.
