Transparent Display LED Layout for High Transmittance Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transparent display apparatuses with light emitting diodes (LEDs) face challenges in maintaining transparency while achieving appropriate display performance, often requiring complex arrangements that reduce screen transparency and hinder visual recognition of images from the back surface side.
Innovation Solution
A transparent display apparatus with a first transparent substrate, light emitting units, and a strip unit, where each light emitting unit includes at least one LED with a size of 10,000 μm² or less, and the area with 20% or less transmittance accounts for 30% or less of the display area, enhancing transparency while maintaining display performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the complexity of the arrangement of constituent elements such as strips is increased to secure appropriate display performance, then the display performance is improved, but the transparency of the screen is reduced
Solution Approach 1:
The patent applies parameter changes by precisely controlling the area ratio of low-transmittance regions to be 30% or less of the total display area, and limiting each LED to 10,000 μm² or less. This quantitative parameter optimization resolves the contradiction by achieving display performance through controlled parameter thresholds while maintaining transparency.
2Illumination intensity
If the area with low transmittance is increased to improve display visibility, then the display performance is enhanced, but the visual recognition of images on the back surface side is hindered
Solution Approach 1:
The patent resolves this contradiction by establishing specific parameter thresholds: the low-transmittance area is limited to 30% or less of the display area, and each LED area is constrained to 10,000 μm² or less. These parameter changes optimize the balance between display visibility and back surface transparency, allowing both functions to coexist effectively.
