Driving instruction modification method and receiver applied to display driver integrated circuit

A driving instruction modification method characterized by a receiver applied to a display driver integrated circuit, the method comprising:

• judging whether a target command received after setting a global parameter satisfies an initialization condition;
• if so, after modifying a driving instruction corresponding to the target command based on the target command and the global parameter, initializing the global parameter;
• otherwise, maintaining the global parameter unchanged;
• after modifying a driving instruction corresponding to the target command based on the target command and the global parameter, the method further comprises:
• detecting whether all the parameters required to be modified in the driving instruction are modified;
• if so, transmitting the modified driving instruction;
• in the case where it is detected that the parameter required to be modified in the driving instruction still has an unmodified parameter, setting a new global parameter after initializing the global parameter, the initialized global parameter and the newly set global parameter being respectively used for determining a parameter required to be modified in the same driving instruction, and the parameters required to be modified determined by both the initialized global parameter and the newly set global parameter being different.
