Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to reduce the overall electric power consumption in terminal devices, including display devices and host processors, while maintaining display quality, particularly when transmitting moving image data, as existing methods like lossy data compression degrade image quality.
Innovation Solution
A transfer control device that identifies the transmission amount of display data and selects between interlace and non-interlace methods for data transmission, allowing for reduced bandwidth and power consumption without degrading image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If lossy data compression is applied to moving image data to narrow bandwidth, then transmission rate is reduced and power consumption is decreased, but display quality is notably degraded
Solution Approach 1:
The patent dynamically switches between interlace and non-interlace transmission methods based on the transmission amount of display data. When transmission amount is large, interlace method is used to reduce bandwidth and power consumption. When transmission amount is small, non-interlace method is used to maintain high display quality. This dynamic adaptation resolves the contradiction by adjusting the transmission strategy according to real-time conditions.
Solution Approach 2:
The patent changes the transmission parameter (interlace vs. non-interlace method) based on the transmission amount of display data. By identifying the transmission amount and selecting the appropriate transmission method, the system optimizes the balance between power consumption and display quality without applying lossy compression.
2Manufacturing precision
If high bandwidth transmission is used for moving image data, then transmission rate is increased and display quality is maintained, but power consumption is increased
Solution Approach 1:
The system dynamically adjusts the transmission method based on transmission amount. When transmission amount is large, it switches to interlace method to reduce power consumption. When transmission amount is small, it uses non-interlace method to maintain high display quality. This dynamic switching resolves the contradiction between quality and power consumption.
Solution Approach 2:
The transmission parameter (interlace vs. non-interlace) is changed based on the identified transmission amount. This parameter change allows the system to optimize power consumption when high bandwidth is available while maintaining quality, and vice versa, resolving the contradiction.
3Use of energy by moving object
If interlace method is used for data transmission, then bandwidth is reduced and power consumption is decreased, but transmission rate is lowered
Solution Approach 1:
The patent dynamically selects between interlace and non-interlace methods based on transmission amount. When transmission amount is large, interlace method is used to reduce power consumption and bandwidth. When transmission amount is small, non-interlace method is used to maintain high transmission rate. This dynamic selection resolves the contradiction between power consumption and transmission rate.
