Display Panel Color-Channel Data Lines for Lower Power Consumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in reducing power consumption while effectively displaying images with multiple colors.
Innovation Solution
The display panel is designed with a configuration where data lines transfer specific color data signals to sequentially arranged light emitting elements, each connected through extending lines and contact holes, and a demultiplexer selectively connects output lines to data lines based on switching signals, optimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If data lines transfer all color data signals to all light emitting elements, then complete image display is achieved, but power consumption increases due to unnecessary current transfer
Solution Approach 1:
The data lines are segmented by color channel, with separate data lines dedicated to transferring red, green, and blue color data signals. This segmentation allows each data line to carry only specific color signals to specific light emitting elements, reducing unnecessary current transfer and power consumption while maintaining complete image display capability
Solution Approach 2:
The demultiplexer dynamically connects output lines to data lines based on switching signals, enabling flexible routing of color data signals. This dynamic connection allows the system to activate only the necessary data lines for current display requirements, optimizing power usage while maintaining manufacturing feasibility through controlled complexity
2Use of energy by moving object
If demultiplexer selectively connects output lines to data lines, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The demultiplexer serves multiple functions: it routes different color data signals to appropriate data lines, enables dynamic power management by activating only necessary signal paths, and maintains compatibility with existing pixel circuit architectures. This multi-functionality justifies the added device complexity by delivering significant power consumption reductions and system flexibility
