Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transmissive display apparatuses often have low light transmittance and image visibility, making it difficult to view backgrounds and images effectively.
Innovation Solution
Incorporating an optical refractive layer with minute holes in a display apparatus, which enhances transmittance and image resolution by allowing background visibility and replicating images at the periphery of light-emitting pixels, using silicon oxide and arranging holes in a diagonal pattern for improved light diffusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transmissive display apparatus is used to allow background visibility, then transmissibility is improved, but image visibility and resolution deteriorate
Solution Approach 1:
The display area is segmented into pixel areas containing light-emitting devices and transmission areas without light-emitting devices. The optical refractive layer is further segmented with minute holes arranged in specific patterns. This segmentation allows different regions to serve different functions: pixel areas for image display and transmission areas for background visibility, while the minute holes in the optical refractive layer redirect light to enhance both image and background visibility simultaneously
Solution Approach 2:
The optical refractive layer acts as an intermediary between the light-emitting devices and the external environment. It contains minute holes that refract and redirect light from the pixel areas through the transmission areas, enabling the background to be visible while maintaining image quality. This intermediary structure resolves the contradiction by mediating the interaction between light emission and background transmission
2Illumination intensity
If the transmission area is increased to improve background visibility, then transmissibility is improved, but the area for displaying images deteriorates
Solution Approach 1:
The invention utilizes the optical dimension by introducing the optical refractive layer with minute holes that redirect light paths. This allows the transmission areas to contribute to both background visibility and image display through optical refraction, effectively using another dimension (optical path) to resolve the spatial trade-off between transmission area and display area

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly improves the visibility of both backgrounds and images by increasing transmittance and resolution, allowing for a clearer view of external environments while maintaining image quality.
Implementation Method 1
an optical refractive layer through which both the image of the background and the light which is emitted from the pixel area are transmitted to outside the display apparatus. The optical refractive layer defines a plurality of minute holes in planar areas of the pixel area respectively corresponding to the light-emitting device and to a periphery of the light-emitting device.
