Display Throughput Control for Thermal Management in Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face performance degradation due to heat, battery consumption, and abnormal frame rates, leading to undesirable shutdowns or performance throttling, which can cause inconvenience to users and degrade system performance.
Innovation Solution
An electronic device equipped with sensors to detect performance degradation factors, such as heat and battery consumption, and a processor that monitors these factors to control display data throughput, reducing graphic processing resolution when necessary, thereby minimizing performance degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the system shuts down or reduces processor frequency to control heat, then heat generation is reduced, but system performance and user experience deteriorate
Solution Approach 1:
The patent extracts the display data throughput control from the overall system throttling mechanism. Instead of reducing processor frequency system-wide, it specifically limits display data throughput to reduce heat generation from the display subsystem while allowing other system components to maintain full performance.
Solution Approach 2:
The patent applies local quality by targeting the display data processing path specifically. It reduces the quality/throughput of display data rendering while maintaining full processing capability for other system functions, creating a localized performance adjustment rather than global throttling.
2Temperature
If processor frequency is reduced to mitigate heating, then heat generation is reduced, but application performance (frame rate, responsiveness) deteriorates
Solution Approach 1:
The patent separates display data processing from the main processor pipeline by controlling display data throughput independently. This extraction allows the main processor to maintain high frequency for application execution while the display subsystem operates at reduced throughput to generate less heat.
3Use of energy by moving object
If system throughput is reduced to control battery consumption, then battery usage is optimized, but system performance and responsiveness deteriorate
Solution Approach 1:
The patent applies local quality by optimizing battery consumption specifically in the display data processing path. It reduces the energy required for display rendering while maintaining full system performance for other functions, creating a localized energy efficiency improvement rather than global performance reduction.
