Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with divided display areas face increased current consumption due to processors handling image processing for the entire display area, including both main and sub-areas, leading to higher power usage.
Innovation Solution
The implementation of a display panel with separate pixel groups and emission lines for each display area, allowing for independent control of power supply through dedicated emission control circuits, enabling selective power management and reduced power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the processor processes images for the entire display area including sub-area, then the display functionality is complete, but the current consumption increases
Solution Approach 1:
The display area is divided into a main display area and a sub-display area, with separate emission control circuits for each region. This segmentation allows independent control of power supply to different display regions, enabling the system to activate only the necessary portions of the display, thus reducing overall current consumption while maintaining required display functionality.
Solution Approach 2:
The emission control circuits enable partial activation of the display area by controlling power supply to specific regions (main area or sub-area) based on operational needs. Instead of always activating the entire display, the system applies power only to the portions currently in use, reducing energy consumption during operations that require only partial display functionality.
2Use of energy by moving object
If the emission control circuits are separated for each display area, then the power consumption is reduced, but the device complexity increases
Solution Approach 1:
The emission control circuit is divided into a first emission control circuit for the main display area and a second emission control circuit for the sub-display area. Each control circuit independently manages power supply to its respective region, enabling selective activation to reduce power consumption. This segmentation of control functions allows the system to activate only the necessary control circuits based on operational requirements, balancing power savings with manageable system complexity.
