OLED Mirror Display with Segmented Reflective Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile phone display surfaces are inadequate for reflecting images clearly, which limits their utility as portable mirrors, despite the potential of OLEDs for next-generation flat panel displays due to their self-light-emitting, view angle independence, and low cost advantages.
Innovation Solution
An OLED design incorporating a transparent substrate with a mirror layer having openings aligned to pixel regions, a transparent insulating layer, and an organic light emitting displaying layer, allowing the mirror layer to reflect images while maintaining display brightness by passing light through the transparent substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional display surface is used, then the display can show images, but it cannot reflect images clearly like a mirror
Solution Approach 1:
The display surface is segmented into multiple pixel regions with different light emission characteristics. Each pixel region can independently control light emission, allowing the overall surface to function as both a display and a mirror by selectively emitting or reflecting light in different areas.
Solution Approach 2:
The display surface dynamically adjusts its optical properties by controlling the light emission state of individual pixel regions. When pixels are turned off, the surface reflects ambient light to function as a mirror; when pixels are activated, they emit light for display purposes, enabling the surface to adapt between mirror and display modes.
Applied Scientific Principles
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 OLED effectively functions as a mirror and maintains good display brightness, enhancing the versatility of mobile devices by allowing them to serve as both display interfaces and portable mirrors.
Implementation Method 1
organic light emitting materials are disposed on the first electrodes and located in the pixel regions
Implementation Method 2
the mirror layer is disposed on the transparent substrate and has a plurality of openings
