Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The MIPI bus's operating frequency interferes with modem communication in game mode, leading to suboptimal communication performance, and existing solutions like hardware upgrades are costly and provide limited improvements.
Innovation Solution
A display control method that dynamically adjusts the MIPI bus's operating frequency to minimize interference by determining the target MIPI operating frequency range corresponding to the game frame rate, selecting the frequency with the least interference, and adjusting the MIPI bus to this frequency, thereby reducing electromagnetic interference and enhancing communication performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the display MIPI bus operates at a fixed frequency to meet game frame rate requirements, then the display performance is improved, but electromagnetic interference on modem communication occurs
Solution Approach 1:
The patent applies dynamics by making the MIPI bus frequency adjustable rather than fixed. The system dynamically changes the MIPI frequency based on detected interference conditions, switching between different frequency values (e.g., 200MHz, 250MHz, 300MHz) to maintain both display performance and communication quality
Solution Approach 2:
The patent changes the operating parameter (frequency) of the MIPI bus to resolve interference. By modifying the frequency parameter from a fixed value to a variable that can be adjusted among multiple options, the system eliminates electromagnetic interference while maintaining adequate display performance for games
2Object-affected harmful factors
If hardware upgrades are implemented to reduce MIPI interference, then communication performance is improved, but device cost increases
Solution Approach 1:
Instead of hardware upgrades, the patent changes the operating parameters (frequency values) of the existing MIPI bus. This software-based parameter adjustment approach eliminates interference without requiring additional hardware components, thereby avoiding increased device cost
Solution Approach 2:
The patent replaces the mechanical/hardware approach (hardware upgrades) with a software/control approach (frequency parameter adjustment). This substitution achieves the same interference reduction goal without the cost and complexity of hardware modifications
3Object-affected harmful factors
If the MIPI bus frequency is adjusted to reduce interference, then communication performance is improved, but display quality may be affected
Solution Approach 1:
The system dynamically adjusts MIPI frequency based on actual interference detection, switching between different frequency values. This dynamic adjustment ensures that display quality requirements are met while minimizing interference, as the frequency is optimized for both purposes rather than being fixed at a single value
Solution Approach 2:
By changing the frequency parameter to a variable that can take multiple values, the system finds an optimal balance between display quality and communication interference. The parameter adjustment allows the MIPI bus to operate at frequencies that satisfy both display requirements and interference reduction goals

AI summary
The embodiments of the present disclosure provide a display control method and related products. The method includes: during the electronic device is running a target game, obtaining a target operating frequency of the modem in response to detecting that the target game initiates a game booster mode; obtaining a first MIPI operating frequency of a display MIPI bus; determining whether the target operating frequency is interfered based on the first MIPI operating frequency; obtaining a target game frame rate of the target game in response to the target operating frequency being interfered; determining a target MIPI operating frequency range list corresponding to the target game frame rate, the target MIPI operating frequency range list comprising a plurality of MIPI operating frequencies; determining a second MIPI operating frequency having least interference on the target operating frequency of the modem from the plurality of MIPI operating frequencies; and adjusting a MIPI operating frequency of the display MIPI bus to the second MIPI operating frequency. In this way, when the electronic device is running a target game, the MIPI operating frequency of the display can be dynamically adjusted without changing hardware design of the electronic device, so that electromagnetic interference on modem communication is eliminated or reduced, and good communication performance is obtained.
