Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
All-around display devices face challenges in reducing power consumption as they are required to constantly output image information from multiple sides, leading to unnecessary energy usage when not all display areas are in use.
Innovation Solution
The implementation of a display area controller and global control signals that allow for selective and independent control of light emission in each display area, using a pixel structure with transistors and an organic light emitting diode, enabling the display areas to be driven based on user suitability and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all display areas constantly output image information, then the all-around display device provides comprehensive display coverage, but power consumption increases unnecessarily
Solution Approach 1:
The display panel is divided into multiple independently controllable display areas (first display area, second display area, third display area, fourth display area). Each display area can be selectively activated or deactivated through separate control signals, allowing the system to provide comprehensive display coverage when needed while consuming less power when only certain areas are in use.
2Use of energy by moving object
If a display area control driver is added to selectively control display areas, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The display area control driver performs multiple functions: it generates global control signals for selective display area activation, works in coordination with existing gate drivers and emission drivers, and can be integrated into the existing display control architecture. This multi-functionality allows power savings without proportionally increasing overall system complexity.
