Description
The present invention relates to a head-mounted display device adjustable to different visual acuities and pupil spacing according to the user.
A head-mounted type display device has appeared, in which a variety of display forms come into view while attaching to the head to view an image. Such a device is called a head mount display (HMD), and the head mount display is positioned adjacent to the eye, so focus adjustment is necessary.
In particular, in recent years, a virtual reality head mount display has been introduced to provide a 3D stereoscopic image, not a 2D image, and a variety of images can be provided by turning a head 360 ° panoramic image as well as a vertical panoramic image according to a user's movement.
The virtual reality head-mounted display is able to provide 3D stereoscopic images by completely blocking ambient light and providing different images to the left and right eyes. In order for a user to recognize two images (a left-eye image and a right-eye image) as one stereoscopic image, the focal distance must be set to a proper value.
When a device such as a motor is provided on the head mount display to adjust an accurate focal distance, the wearing feeling is reduced, and therefore, a focal length adjusting device with a simple structure is required.
The head-mounted display unit wears off glasses, so if the visual acuity is bad, it can not see the correct image, and the visual acuity changes when the lens is worn and when the lens is not worn. That is, it is necessary to be able to adjust a different focal distance according to the user, and furthermore, there is a problem that the focal distance must be reset depending on whether the lens is worn by the same user. In addition, since there is a difference in eye interval according to the user, the 3D image may not be displayed clearly according to the user and may cause dizziness.
It is an object of the present invention to provide a head-mounted display device including a focal length adjusting section and a horizontal adjusting section which coincides with a distance between a pair of lenses and an interval between pupils.
A housing having a front surface shielded and a rear surface including an opening; A pair of left and right optic modules; A head fixing part fixing the housing to a user's head; A horizontal adjustment unit including a horizontal adjustment button exposed to the outside of the housing and guiding horizontal movement of the pair of visual modules; And a wheel having one side exposed at an outer side of the housing, the focus adjusting unit adjusting a distance between the barrel and the display unit; Wherein the pair of visual modules comprises: a display unit located inside the housing; A barrel having one side positioned within the housing and the other side exposed to the outside of the housing through the opening; A lens fixed to the barrel; And a barrel accommodating unit coupled to a back surface of the display unit and surrounding a periphery of the barrel, wherein the focus adjusting unit and the horizontal adjusting unit include a head mount capable of operating independently of the focus adjusting unit and the horizontal adjusting unit of another time module A display device is provided.
Wherein the focus adjusting unit includes a screw rotatably fixed to one of the display frame or the barrel and inserted into a screw groove formed in the other one of the display frame or the barrel,
The wheel is coupled to the outer periphery of the screw. When the wheel is rotated around the screw, the screw is drawn in and out of the screw hole, and the position of the barrel can be adjusted.
The screw may include a metal, and may further include a magnet disposed adjacent to the screw.
A first guide hole formed in the barrel; A second guide hole formed in the display frame; And a guide shaft passing through the first guide hole and the second guide hole and parallel to the screw, wherein when the barrel is moved, the first guide hole or the second guide hole moves along the guide shaft .
And the first guide hole may be positioned in the front direction of the housing than the second guide hole.
The horizontal adjustment unit includes a rail fixed to the housing and extending in the left and right direction. The visual module is inserted into the rail, and can be moved laterally along the rail when the horizontal adjustment button is moved left and right.
The rail may further comprise a metal, and a magnet provided in the visual module and disposed adjacent to the rail.
Wherein the focus adjustment unit includes a screw fixed to one of the display frame or the barrel and inserted into a screw groove formed in the display frame or the other one of the barrel and having threads on an outer surface thereof, And may be disposed between the screw and the visual module.
Wherein the horizontal adjustment button comprises: a button portion exposed to the outside; And a locking pawl which passes through a button opening formed in the housing at the button portion and is coupled to the time module, wherein the button opening may extend in the left and right direction.
The leveling button may include a wheel opening that exposes one side of the wheel.
The opening formed in the housing may be longer in the lateral direction than the size of the barrel.
And a pair of spacers coupled to the left and right sides of the barrel and being equal to or longer than the difference between the diameter of the barrel and the left and right lengths of the openings.
According to at least one embodiment of the present invention, the focal distance can be adjusted according to the visual acuity of the user, and a horizontal adjustment unit that matches the distance between the pair of lenses and the interval between the pupils can be more comfortably appreciated .
In particular, the present invention can control the left and right eye modules independently of the left eye and the right eye, respectively, and can adjust the distances between the eyes and the nose to be finely adjusted.
Further scope of applicability of the present invention will become apparent from the following detailed description. It should be understood, however, that the detailed description and specific examples, such as the preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art.
