Transparent Display Layer Layout for Misalignment-Tolerant Transmittance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transparent double-sided displays face challenges in maintaining high transmittance when bonded, especially due to misalignment issues which affect the brightness of the background seen through the display.
Innovation Solution
The display device consists of two transparent displays with alternating transmission and non-transmission areas, where the non-transmission areas of one display are designed to overlap and hide the smaller non-transmission areas of the other display, ensuring that the transmittance remains consistent even with misalignment, by strategically arranging display areas and transmission areas in patterns such as stripes or dots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two transparent displays are bonded to form a double-sided display, then information display capability is improved, but transmittance decreases due to misalignment between non-transmission areas
Solution Approach 1:
The patent applies asymmetry by making the non-transmission areas of the first transparent display larger than those of the second transparent display. This asymmetric design ensures that the larger non-transmission areas always cover the smaller ones regardless of bonding misalignment, maintaining high transmittance while enabling double-sided information display capability.
2Illumination intensity
If non-transmission areas are made larger to cover misalignment, then transmittance is maintained, but display area is reduced
Solution Approach 1:
The patent applies local quality by creating asymmetric non-transmission areas where only specific regions are enlarged to cover misalignment, while other display areas remain optimized for information display. This localized modification maintains overall display effectiveness while ensuring transmittance coverage.

Function Achieved in This Case
This configuration maintains high transmittance and consistent brightness regardless of misalignment, allowing for optimal visibility of both the display information and the background, enhancing the display's performance in various environmental illuminance conditions.
Implementation Method 1
The one or more first transmission areas transmit background light. The one or more second transmission areas transmit background light.

AI summary
A display device includes a first transparent display including one or more first transmission areas and one or more first non-transmission areas that include one or more first light emitting elements; and a second transparent display bonded to the first transparent display. The second transparent display includes one or more second transmission areas and one or more second non-transmission areas that include one or more second light emitting elements. The one or more second non-transmission areas include a third non-transmission area. The one or more first non-transmission areas include a fourth non-transmission area overlapping the third non-transmission area. An area of the third non-transmission area is smaller than an area of the fourth non-transmission area. The third non-transmission area is hidden by the fourth non-transmission area when viewing the display device while facing the first transparent display.
