Stacked OLED and Electronic Paper Display with Content-Aware Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic devices are limited by a single display type optimized for a specific type of visual content, failing to efficiently handle multiple types of content, which can lead to suboptimal performance or power consumption.
Innovation Solution
An electronic device with multiple displays, including an OLED display for dynamic content and an electronic paper display for static content, where control circuitry determines the type of content to display on each based on features like rate of change, allowing for efficient switching between display types to optimize power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a single OLED display is used for all visual content, then color and dynamic content can be displayed, but power consumption increases for static content
Solution Approach 1:
The display system is segmented into two separate display devices: an OLED display for dynamic/color content and an electronic paper display for static content. This segmentation allows each display type to be optimized for its specific content category, reducing overall power consumption while maintaining versatility across different content types.
2Use of energy by moving object
If a single electronic paper display is used for all visual content, then power consumption is minimized, but color and dynamic content quality deteriorates
Solution Approach 1:
Different display quality characteristics are applied locally to different content types: the OLED display provides high-quality color and dynamic content, while the electronic paper display provides sufficient quality for static content. This local quality approach ensures that display quality is optimized for each content type without unnecessarily compromising overall system performance.
3Adaptability or versatility
If multiple display types are used, then content optimization is improved, but device complexity increases
Solution Approach 1:
The control circuitry is designed with multi-functionality to manage both OLED and electronic paper displays. It can automatically determine content characteristics and selectively activate the appropriate display type, providing universal content optimization across different display technologies without requiring separate control systems for each display.

AI summary
An exemplary electronic device includes a first display and a second display. The first display includes a number of first pixels. Each first pixel defines a first display region. Each first display region displays first visual content when voltages are applied to the first pixel and displays no first visual content when no voltage is applied to the first pixel. Each first display region is transparent or translucent when displaying no first visual content. The second display includes a number of second pixels. Each second pixel defines a second display region for displaying second visual content. The first visual content is viewable whether or not the second display displays the second visual content, and the second visual content is viewable when one or more first display regions corresponding to the second display region are transparent or translucent.
