Description
Technical field
Of the present invention relevant for head mounted display, especially refer to the focus-adjustable head-mounted type display system that the tool digital content shows and be used to realize the device of this system, the present invention can adjust its focal length to adapt to the person's of wearing eyesight for the image that shows on head mounted display.
Background technology
At U.S. Pat P NO.6, a kind of head-mounted display apparatus is proposed in 369,952, give the user and see and look to transmit an image that produces, preferably the image that should produce is in conjunction with the image in the external world.Comprise a housing department in this head-mounted display apparatus optical module is fixed in this housing department, hide an image generator so that high-quality image to be provided by at least two cover curtains; This device still comprises the installation that can take away and hides unit or movable device, and converts display screen to imagescope from the lens of a penetration, and can carry out reverse conversion.This device can be installed in user's head, and still allows the user to use the glasses of traditional type, and can divide with this HMD easily and open, and makes HMD can use (for example being used to see a film) separately.
At U.S. Pat P No.6,611,385 propose a wearable display system, this system comprises a display panel to show the signal of handling according to predetermined mode, and this wearable display system comprises a grating, with output signal from this display panel, one optical waveguide is with via this grating steering signal, one amplifying lens is somebody's turn to do via the optical waveguide amplifying signal to amplify, and this signal is shown the eyes that give the user, forms optical waveguide in conjunction with one or more matrix.According to wearable display system, can this optical waveguide be installed with adjusting, and further make and install this optical waveguide individually with up to specification; Therefore, use minimum time and this wear-type display system of effort manufacturing.
At U.S. Pat P No.5, an exquisite type virtual image display system is proposed in 991,084, it comprises a micro-display, and one comprises first of three faces amplifies electro-optical device, and one shows input face, one reflection/penetration surface, and reflective first an amplifier module face, and one second amplification electro-optical device.The light of demonstration target enters at first of this demonstration input face and amplifies electro-optical device, this light is propagated in this first amplification electro-optical device, make this light project a zone of backreflection formula penetration surface, this face has a part at least in this second amplification ken that electro-optical device provided, with to reflecting/reflection/penetration surface of first angle of penetration surface, make light by reflecting on the reflection/penetration surface, and this reflective first amplifier module face of guiding; This first amplifier module face reflection corresponds to source target light, as a virtual image of amplifying, the virtual image of this amplification second incident angle with a pair of should the reflection/penetration surface in this first amplification electro-optical device sends back this reflection/penetration surface then, leaves this first amplification electro-optical device via this reflection/penetration surface.A plurality of this second amplifies electro-optical devices and receives from this first virtual image of amplifying the amplification of electro-optical device, and the synthetic amplification virtual image of the amplification virtual image of this source target shown gives the observer.
Again, U.S. Pat P No.6 proposes a camera display system in 683,584, and this system is installed in the matrix form display module on the housing department via one and display message is located this housing department with corresponding user a glance at least; This display is connected to a video signal or image sensor, the information or the image that make the user to see to show on this display; This display can be installed to this housing department, makes the user can move this display so that this display within this user's the ken or outside.
In addition at U.S. Pat P No.6, the head-mounted display apparatus of a simple eye type is proposed in 680,802, this device is exquisiteness and be suitable for user's wearing quite, comprises a viewer and an elastic parts; This viewer comprises a LCD, a headprism, and one penetrates mirror, a mirror holder, and a microphone.This main lens imports an image, again image is presented on the LCD, so that the user can see this image at least at a glance, this penetrates mirror and is fixed on the main lens, this microphone is installed on the mirror holder, this elastic parts comprises a nose frame so that this elastic parts is supported, so this viewer can be positioned at the precalculated position before user's eyes.
But the known techniques of all above-mentioned explanations only proposes photosystem or physical construction, gives the wear-type display system so that image is shown, still without any known techniques proposes structure of watching correlation of attributes or mechanism any and human eye.Because many people have the disease of eye, long sight for example, myopia, therefore amblyopia or stravismus etc. can't clearly watch clearly image, so when normally clearly image is presented at the display screen of this head-mounted display apparatus, for the beholder that eye illness is arranged, be the image that blurs on the contrary.For example myope puts on one's glasses usually, to adjust the focal length of image, makes the focal length of image can drop on user's the retina, and the still general head-mounted display apparatus of dressing does not often have or inconvenience is put on one pair of glasses again.So traditional head-mounted display apparatus is unsuitable for the wearing of eye illness on the contrary, therefore be necessary a kind of head-mounted display apparatus that can adjust focal length, so that the user can watch clearly image.
And another kind is applied as and makes head-mounted display apparatus to replace the function of glasses fully, especially for the amblyope this needs is arranged more.Promptly take in image, image is handled in advance making the user can clearly see image on the display screen again to be presented at via a camera.But the head-mounted display apparatus that in all known techniques, all has above-mentioned functions less than proposition.
