Document Type and Number:
WIPO Patent Application WO/2021/082798
Kind Code:
A1
Abstract:
A head-mounted display device, comprising a frame (10) and two display modules (20) provided on the frame (10). The two display modules (20) are arranged corresponding to two eyes of a user respectively, and each display module (20) comprises a display screen (21), a free-form surface lens (22) and an adjustment mechanism (26). The display screens (21) are slidably assembled on the frame (10) along a first direction (X). The free-form surface lenses (22) at least comprise first optical surfaces (23) arranged corresponding to the eyes of the user, and the free-form surface lenses (22) are used to guide and project light emitted from the display screens (21) to the first optical surfaces (23) so as to form effective display regions (24) on the first optical surfaces (23). The adjustment mechanisms (26) are connected to the display screens (21), and are used to drive the display screens (21) to slide so as to adjust the positions of the effective display regions (24) on the first optical surfaces (23). The first direction (X) is the arrangement direction of the free-form surface lenses (22) of the two display modules (20). Thus, the positions of the effective display regions (24) of the display modules (20) may be adjusted according to the positions of the pupils of the user, and the convenience of adjustment is increased.
