The realization of the utility model object, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model first embodiment proposes a kind of wear-type virtual reality display device, comprises shell 40, display screen 10, eyepiece 30 and object lens 20, described display screen 10, for showing the video image of handstand; Described object lens 20, for aligning the video image of described handstand; Described eyepiece 30, for amplifying the video image of described levelling; Described display screen 10, described object lens 20 and described eyepiece 30 are fixed on described shell 40, and described object lens 20 are between described display screen 10 and described eyepiece 30, and described display screen 10, described object lens 20 and described eyepiece 30 are positioned on same optical axis.Described display screen 10 is TFT (ThinFilmTransistor, thin film transistor (TFT)) shield or OLED (OrganicLight-EmittingDiode, Organic Light Emitting Diode) screen, in the present embodiment, the resolution of described display screen is 1080P, is of a size of 4 cun.
The wear-type virtual reality display device that the present embodiment provides, carries out many times of amplifications by the image shown smaller screen, achieves the sharpening display of video image; Adopt undersized display screen, reduce cost.
As shown in Figure 2, the optical principle of the wear-type virtual reality display device of the present embodiment proposition is as follows:
First display screen 10 receiver, video stream, the image AB of handstand is presented at display interface, described video flowing can be that computer sends over, such as, by the wired of computer or the mode of wireless transmission, the mode as wired transmission adopts HDMI (HighDefinitionMultimediaInterface, HDMI (High Definition Multimedia Interface)) transmission mode, the mode of wireless transmission can adopt WI-FI (Wireless-Fidelity, Wireless Fidelity) or Bluetooth transmission mode.Described video flowing also can be sent by wear-type virtual reality display device itself, such as, by the video image that the camera collection that wear-type virtual reality display device is built-in stands upside down, and the video image of the described handstand collected directly is sent to display screen 10 after image procossing, show via display screen 10.Then the video image of handstand that display screen 10 presents is projected onto on object lens 20, by the refraction of object lens 20, the video image of described handstand is aligned for upright image B ' A ', through the further amplification by eyepiece 30 again, the virtual image B of upright amplification is presented in the front of human eye " A ", thus the image achieved smaller screen presents carries out several times amplification and sharpening display.
With further reference to Fig. 1, the wear-type virtual reality display device that the present embodiment provides, described eyepiece 30 comprises the first eyepiece 31 and the second eyepiece 32, and described object lens 20 comprise the first object lens 21 and the second object lens 22, and described first eyepiece 31 and the first object lens 21 coexist on primary optic axis 41; Described second eyepiece 32 and the second object lens 22 coexist on the second optical axis 42.The image of the left and right split screen form that computer sends over carries out left and right split screen display in described display screen 30, and the left and right picture of split screen display is divided into two-way to project, and wherein leads up to the first object lens 21 and the first eyepiece 31 to project in retina of left eye; Separately leading up to the second object lens 22 and the second eyepiece 32 projects in retina of right eye, thus forms horizontal parallax, generates the 3-D view of a solid in the front of human eye.
The wear-type virtual reality display device that the present embodiment provides, by the image shown by left and right split screen, projects right and left eyes respectively, thus forms horizontal parallax, generating three-dimensional figures picture.
As shown in Figure 3, the wear-type virtual reality display device that the present embodiment provides, described eyepiece 30 is plano-convex lens, and described plano-convex lens comprises crowning 33 and burnishing surface 34, one side near described object lens 20 is crowning 33, and the one side away from described object lens 20 is burnishing surface 34.
The wear-type virtual reality display device that the present embodiment provides, eyepiece adopts plano-convex lens, thus covers mankind's eyes visual angle completely, realizes observing with great visual angle.
With further reference to Fig. 1, the wear-type virtual reality display device that the present embodiment provides, described shell 40 5 face closure, an opening, described eyepiece 30 is installed on the opening surface of described shell 40.The curved depression of opening surface of described shell 40, unique arcuate structure meets ergonomics.
The wear-type virtual reality display device that the present embodiment provides, adopts closed design, avoids the impact of light leak on display effect, thus obtains better sharpness.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
