Embodiment Construction

[0028] Exemplary, such as figure 1 Shown is a front view of a vision care device provided by the present application, and the vision care device includes a housing 1, an outer window glass 2, a PC motherboard 3, a base 4, a first drive unit 65 and a display arranged in the housing 1 Box 6.

[0029] The shell 1 is equivalent to a protective cover, and is slidably connected with the display box 6 arranged in the shell 1, providing a regular mobile platform for the display box 6, which is convenient for cooperating with the first display 60 and the second display 61 to realize large-scale display. Dimensional 3D health effects.

[0030] The base 4 is fixedly connected with the shell 1, providing a supporting point for the whole device.

[0031] The outer window glass 2 is inlaid on the side of the housing 1 facing the viewer, and the viewer can watch the 3D picture inside the housing 1 through the outer window glass 2 .

[0032] The PC motherboard 3 is arranged in the base 4, ...

Abstract

The invention relates to the technical field of vision health care, in particular to a vision health care device. The vision health care device comprises a casing, outer view window glass, a PC main board, a base, a first driving unit, a displayer box, a first displayer, a second displayer, a displayer slideway, a PBS board, a signal processing board, a second driving unit, a third driving unit and inner view window glass; the PC main board transmits a 3D video signal to the signal processing board for decomposition, then the 3D video signal is transmitted to the first displayer and the seconddisplayer, horizontal polarized light emitted by the first displayer is projected to the PBS board at the incidence angle of 45 degrees, and refracted light is projected to a viewer at the emergenceangle of 45 degrees; vertical polarized light emitted by the second displayer horizontally penetrates through the PBS board to be projected to the viewer, a horizontal polarizer and a vertical polarizer are worn on the left eye and the right eye of the viewer respectively, and a 3D vision is formed through binocular image fusion. The driving units drive the first displayer, the second displayer and the displayer box to cooperatively move to achieve the adjustment and collection linkage of the eyes, and various movement modes can be compiled to adapt to various patients with poor vision.

Description

technical field [0001] The present application relates to the technical field of vision care, in particular to a vision care device. Background technique [0002] With the overall improvement of economic and cultural construction, the incidence of eye diseases in different age groups is also increasing year by year, especially the incidence of myopia remains high among primary and middle school students, which seriously affects the physical fitness of our nationals. The eye is the cause of myopia. At present, there are many kinds of products and instruments for relieving eye fatigue and treating eye diseases. Among them, vision care and 3D display devices based on binocular image fusion have good health care effects for relieving eye fatigue and treating eye diseases. [0003] At present, the current implementation of 3D display technology based on large-scale display has a polarized light method, that is, the viewer wears polarized light glasses, and the polarized light pr...
