Method and device for displaying main screen and auxiliary screen of vehicle machine system and electronic equipment

The invention relates to a method and device for displaying a main screen and an auxiliary screen of a vehicle machine system and electronic equipment. The method comprises the steps of setting a main screen frame rate and an auxiliary screen frame rate for the main screen and the auxiliary screen respectively; and respectively setting matched main screen refresh frequency and auxiliary screen refresh frequency for the main screen and the auxiliary screen according to the main screen frame rate and the auxiliary screen frame rate. Preferably, the method further comprises a step of monitoringthe bandwidth of the CPU or the GPU, and adjusting the main screen frame rate and/or the auxiliary screen frame rate according to the bandwidth of the CPU or the GPU. Compared with the prior art, by adjusting the frame rates of the main screen and the auxiliary screen respectively, the CPU/GPU load is relieved, the processing capacity of the CPU/GPU is improved, the stability of the system is improved by releasing resource
