OLED Display with Regional Transparency for Optoelectronic Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional OLED displays are not transparent or only partially transparent, limiting their integration with optoelectronic components, requiring cutouts or notches as the display size increases, which affects design flexibility and usability.
Innovation Solution
Designing an OLED display with a transparent or semi-transparent substrate that includes regions with varying light emissive areas, allowing higher light transmittance in areas with optoelectronic components by varying the proportion of light emissive areas and transparent or semi-transparent areas in different pixel regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional OLED displays are used with opaque substrates, then display coverage can be maximized, but integration with optoelectronic components is limited requiring cutouts or notches
Solution Approach 1:
The patent applies local quality by creating different transparency characteristics in different regions of the display. The display includes a first region with standard opaque pixels and a second region with transparent or semi-transparent pixels, allowing each region to serve different functions - the opaque region maximizes display coverage while the transparent region enables optoelectronic component integration without cutouts
2Adaptability or versatility
If transparent or semi-transparent pixels are used to accommodate optoelectronic components, then integration flexibility is improved, but light transmittance and resolution may be compromised
Solution Approach 1:
The patent applies parameter changes by varying the transparency parameter across different pixel regions. The transparent or semi-transparent pixels in the second region have modified optical parameters compared to the opaque pixels in the first region, allowing optimization of both integration capability and light transmittance properties through controlled parameter variation
3Ease of manufacture
If uniform pixel structure is used across the entire display, then manufacturing is simplified, but functionality for both high coverage and component integration cannot be achieved
Solution Approach 1:
The patent applies segmentation by dividing the display into distinct functional regions - a first region with opaque pixels for maximum display coverage and a second region with transparent or semi-transparent pixels for optoelectronic component integration. This segmentation allows each region to be optimized for its specific function while maintaining overall manufacturing feasibility

AI summary
In one example aspect, a device comprises an organic light emitting diode (OLED) display. The display comprises a transparent or semi-transparent substrate and includes a first region comprising a plurality of first pixels and a second region comprising a plurality of second pixels. A first proportion of each first pixel comprises a first light emissive area, a second proportion of each second pixel comprises a second light emissive area, and the first proportion is different to the second proportion, wherein the first proportion comprises a ratio of a size of the first light emissive area to a size of each first pixel, and the second proportion comprises a ratio of a size of the second light emissive area to a size of each second pixel.
