Dynamic MIPI Frequency Adjustment for RF Interference Control

The patent implements dynamic frequency adjustment of the MIPI interface by introducing a frequency management module that monitors electromagnetic interference levels and adjusts the MIPI operating frequency in real-time. Instead of using a fixed frequency, the system dynamically switches between multiple predefined frequency values (e.g., 500MHz, 550MHz, 600MHz) based on detected interference conditions, thereby resolving the contradiction between maintaining efficient data transmission and avoiding electromagnetic interference with communication modules.

The patent changes the operating parameter (frequency) of the MIPI interface from a fixed value to a variable that can be adjusted based on system conditions. The frequency management module maintains a set of candidate frequency values and selects appropriate frequencies by changing this key parameter, allowing the system to optimize both data transmission efficiency and electromagnetic compatibility under different operating conditions.

The patent avoids hardware modifications by changing the operating parameters (frequency values) of the existing MIPI interface. The frequency management module uses software-based frequency selection from a predefined set of values to reduce electromagnetic interference, eliminating the need for costly hardware upgrades while achieving the desired interference reduction effect.

The patent replaces the mechanical/hardware approach (hardware upgrades) with a software-based solution (frequency management module that adjusts operating parameters). This substitution allows interference reduction to be achieved through software control of the MIPI frequency rather than through physical hardware modifications, thereby reducing device cost.

The patent implements a dynamic frequency adjustment mechanism where the MIPI operating frequency is continuously monitored and adjusted based on real-time electromagnetic interference conditions. The frequency management module switches between multiple predefined frequency values to optimize both communication stability and display transmission performance, ensuring that neither function suffers significant degradation under different operating conditions.

The patent uses a set of predefined frequency values that are carefully selected to balance the needs of both MIPI data transmission and modem communication. By having multiple candidate frequencies available, the system can choose the most appropriate frequency for current conditions, applying partial adjustments rather than extreme changes that would severely impact either function.
