Abstract
The present invention relates to a method and system for actively adjusting diopter of a head-mounted display, and a head-mounted display. The method includes the following steps: adjusting a relative distance between a displaying component of the head-mounted display and an optical component by a motor driving component; presetting a mapping relationship between a diopter value and a motor pulse number; accordingly converting into a control signal for the motor driving component according to the mapping relationship; and actively adjusting the relative distance between the displaying component of the head-mounted display and the optical component by the motor driving component according to the control signal. A target diopter value is inputted and converted into a corresponding control signal. The motor driving component actively adjusts the relative distance between the displaying component of the head-mounted display and the optical component according to the control signal.
