Abstract
Description
本發明是有關於一種顯示裝置,且特別是有關於一種頭戴顯示裝置。The present invention relates to a display device, and more particularly to a head-mounted display device.
頭戴顯示裝置作為當前最為廣泛使用的虛擬實境設備,使用者需將其穿戴於頭部,並使顯示螢幕貼近眼部,藉以讓三維虛擬場景的影像直接呈現在眼前,從而在虛擬實境體驗的過程中獲致更佳的臨場感。Head-mounted display devices are currently the most widely used virtual reality equipment. Users need to wear them on their heads and make the display screen close to the eyes, so that the images of the three-dimensional virtual scene can be directly presented in front of the eyes, thus in the virtual reality. Get a better sense of presence during the experience.
由於不同的使用者的視力狀況各有差異,因此常見的頭戴顯示裝置整合有物距調節機制,以讓使用者依據個人的視力狀況調整顯示器與透鏡之間的距離,從而獲得良好的成像品質與視覺體驗。一般來說,應用於頭戴顯示裝置的物距調節機制大多為手動調節機制,使用者可透過手指撥動齒輪組,以藉由齒輪組與顯示器的配合驅動顯示器移動靠近或移動遠離透鏡。然而,採用手動方式調節物距,對於使用者來說較為不便。Since different users have different vision conditions, common head-mounted display devices integrate an object distance adjustment mechanism to allow users to adjust the distance between the display and the lens according to the individual's vision, so as to obtain good imaging quality And visual experience. Generally speaking, most of the object distance adjustment mechanisms applied to head-mounted display devices are manual adjustment mechanisms. The user can move the gear set with fingers to drive the display to move closer to or move away from the lens through the cooperation of the gear set and the display. However, it is more inconvenient for the user to adjust the object distance manually.
