Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display devices face challenges in reducing power consumption while maintaining high response speed, brightness, and wide viewing angles, especially when their mechanical flexibility allows for bending or unfolding, which increases power usage in non-display areas.
Innovation Solution
A foldable display device with a timing controller that analyzes input data signals to determine folded areas and blocks signal transmission to these areas, reducing power consumption by only activating display areas visible to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is made flexible to enable folding, then mechanical adaptability is improved, but power consumption increases in non-display areas
Solution Approach 1:
The display panel is divided into multiple independent data driver regions, each capable of being independently controlled. The timing controller segments the data signal transmission by identifying folded areas and blocking data signals only to the folded region while maintaining transmission to the display area, thereby reducing overall power consumption while preserving mechanical flexibility
Solution Approach 2:
The system dynamically adjusts data signal transmission based on the folding state. The timing controller continuously monitors the display panel configuration and dynamically blocks or allows data signal transmission to different regions, enabling the display to adapt its power consumption profile to its current mechanical state
2Reliability
If data signals are continuously transmitted to all areas, then image display completeness is improved, but power consumption increases
Solution Approach 1:
The timing controller extracts and removes the folded area information from the complete data signal stream. By analyzing the data signal to identify which regions correspond to folded areas, the system selectively blocks only the unnecessary portions while maintaining complete image display in the visible display area
Solution Approach 2:
The timing controller performs self-analysis of the input data signal to automatically determine folded areas without requiring external sensors. This self-service capability allows the system to autonomously optimize power consumption by blocking data signals to folded regions while ensuring complete image display in active regions
3Measurement precision
If external sensors are added to detect folded areas, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The timing controller utilizes its existing data signal processing capabilities to analyze and identify folded areas autonomously. By examining characteristics of the data signal and correlating them with display panel geometry, the system achieves folded area detection without requiring any additional external sensors or detection devices
Solution Approach 2:
The timing controller performs multiple functions: it generates timing signals, processes data signals, analyzes folded areas, and controls data driver operation. This multi-functionality eliminates the need for dedicated detection sensors, reducing device complexity while maintaining detection accuracy
