To a certain extent, the head-mounted display part can be made thinner and more comfortable to wear; in addition, since the processor is not in the head-mounted display part, there will be no problem of uncomfortable wearing due to overheating of the processor.

However, in the split-type head-mounted device in the related art, the head-mounted display part can only be used when it is connected to the host part through a cable, and cannot be used alone, which has poor flexibility and reduces user experience.

It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art.
