Display Control Method for Dynamic Region Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High refresh rates in display technology put pressure on IC hardware and increase power consumption, as existing methods require transmitting and processing entire frames at high frequencies.
Innovation Solution
A display control method that determines dynamic and static regions within each frame, transmitting only the image data for the dynamic region, and using end-of-transmission identifiers and configuration commands to manage the refresh process, thereby reducing data transmission and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If entire frame data is transmitted at high refresh rates, then display refresh rate is improved, but data transmission amount and power consumption increase
Solution Approach 1:
The patent divides the display frame into static regions and dynamic regions, transmitting data only for the dynamic region rather than the entire frame. This segmentation allows high refresh rates to be achieved for dynamic content while reducing overall data transmission by excluding static content from frequent updates.
Solution Approach 2:
The patent extracts and transmits only the necessary dynamic region data from the full frame, separating it from static region data. This extraction approach reduces the quantity of transmitted data while maintaining the refresh rate for the dynamic portion, directly resolving the contradiction between refresh rate and data transmission amount.
2Speed
If entire frame data is transmitted at high refresh rates, then display refresh rate is improved, but power consumption increases
Solution Approach 1:
By segmenting the frame into static and dynamic regions, the patent reduces the amount of data processing and transmission required, thereby lowering power consumption while maintaining high refresh rates for the dynamic region.
Solution Approach 2:
The patent extracts only the dynamic region data for transmission, eliminating the need to process and transmit static region data at high frequencies. This extraction significantly reduces power consumption associated with data transmission and processing while preserving high refresh rates for content that actually changes.
3Quantity of substance
If regional transmission format is used, then data transmission amount is reduced, but system complexity increases
Solution Approach 1:
The patent introduces region identification information to mark static and dynamic regions, which adds some complexity but enables efficient data transmission by allowing the system to quickly identify and process only the necessary dynamic region data without transmitting entire frame data.
Solution Approach 2:
The patent uses region identification information as an intermediary element that facilitates the regional transmission process. This intermediary allows the system to efficiently distinguish between static and dynamic regions, enabling reduced data transmission without requiring complex analysis of each pixel or region.
