Problems solved by technology

Moreover, in the process of rapid focus adjustment, a large amount of blood in the microvessels around the eyeball will cause pressure on the eyeball. The high intraocular pressure caused by long-term and frequent focus adjustment will not only cause discomfort to the human eye, but also seriously Those who are more afraid of the risk of retinal detachment! Therefore, if this kind of real image projection device is applied to a glasses-type display device, when the observation time (within a few hours) is prolonged, the intraocular pressure of the observer will increase, resulting in symptoms of dizziness and discomfort, and even severe retinal detachment. Therefore, it is not s

Embodiment 1

[0051] Please refer to Figure 8 , Figure 8 It is a sectional view of the interior of the glasses-type image display device of the present invention. The present embodiment includes a housing containing two L-COS microdisplays 210 and 211, two light sources 215, two triangular mirrors 220 and 221 (reflecting units), two non-equal curvature convex lenses 230 and 231 (refracting lens groups), And two concave imaging areas 240 and 241 (virtual imaging unit) processed by partial mirror surface. Wherein, the two microdisplays 210 and 211, and the light source 215 are placed in the center of the housing, and the other side of the two microdisplays 210 and 211 are respectively equipped with a prism 220 and a prism 221, so that the two microdisplays 210 and 211 211 is not between the two triangular prisms 220 and 221. Convex lenses 230 and 231 are respectively placed under the triangular prisms 220 and 221 , and virtual image forming areas 240 and 241 are respectively placed under...

Embodiment 2

[0057] The structure of this embodiment is roughly the same as that described in Embodiment 1, except that the virtual image imaging unit 240 is replaced by a flat mirror by a concave mirror. In this way, the formed image is only refracted and magnified by the convex lens 230 once, and then transformed into a virtual image by the plane mirror, which does not have the magnification function. However, the magnification and function of the structural image in this embodiment can still be accomplished by the convex lens 230 that refracts light.

Embodiment 3

[0059]The structure of this embodiment is roughly the same as that described in Embodiment 1, except that the virtual image imaging unit 240 is replaced by a concave lens with a reflectivity of 40% by a concave mirror; its imaging principle and magnification are the same as those described in Embodiment 1. But after replacing it with a concave lens, the observer can see the external environment at the same time when observing the image. And because the device of the present invention forms a virtual image by refraction projection, when a concave lens is used as the virtual image imaging unit, the light rays that transmit the concave lens have a relatively large angle of refraction and deflection. People with glasses-type displays will not see the images and data that the user is using or receiving. It has good confidentiality and privacy, and will not interfere with other people around.

Abstract

A dimmer dioptric imaging display machine mainly comprises two display units; two reflection units located by one side of said display unit to polarizedly refract the sending light from display unit and with two display units between the two reflection units; two refractor mirror sets located by one side of said reflection unit but the second refractor set isn't located in the line formed by the reflection unit and first refractor set; and two virtual image forming sets separately located by two other sides of the two refractor sets to polarizedly refract the light sent from refractor and its image is converted into virtual image through virtual image forming set; the refractor set located between reflection unit and the virtual image forming set. And the image displayed in the display unit is polarizedly refracted into a handstand real image by the refractor set through reflection unit and again is converted into a virtual image with handstand direction with original image through virtual image forming set.

Description

technical field [0001] The invention relates to an image display device, especially an image display device suitable for glasses or helmets. Background technique [0002] In recent years, various audio-visual equipment and display devices have been improved with each passing day. In addition to enhanced functions, thin, light, small, and portable displays have also become the mainstream of display development. One of the emerging display devices is virtual reality (virtual reality) technology. The integration of various technologies, such as display technology, computer technology, sensory technology, and sound effect technology, has reduced the original large-sized audio-visual equipment into a portable glasses-type projection display device. Although the general flat panel display is light in weight, its size is limited by material weight and cost, and it cannot achieve the effect of enlarging the image size and being easy to carry at the same time. Therefore, the current...
