Pupil Distance

In order to move the display flexibly , the mechanical structure is dominated by the vertical adjusting mechanism , pupil distance adjusting mechanism , the rotating mechanism . Pupil distance adjustment mechanism can achieve the 37 mm course and 4 mm fine-tuning .

该机械结构包括垂直调节、瞳距调节以及旋转调节等机构，实现了显示器的灵活移动。
