Transparent glasses television

Abstract

The invention relates to a glasses television, in particular to a transparent glasses television which can simultaneously watch the external real scenery and virtual images. The glasses television comprises an eyeglasses type front frame and ear handles, a display device, an optical lens group and a reflection mirror are arranged on the front frame, a prism combined part image synthesizer consists of two prisms, and the hypotenuses of the two prisms are adhered by 45 degrees. The glasses television has the advantages that: the problems of difficult assembly and adjustment of a single reflection surface and the dislocation problem of the virtual images and the external real scenery on an optical axis are solved; the ghost image problem is solved; the visual field of a system is increased without the great increase of the size, and a condenser component allows the NA of the system to be very large, thereby improving the observation subjective brightness and having great observation effect and good image quality; the light intensity and the contrast of the virtual images and the external real scenery can be adjusted, the virtual images and the real environment have the similar spatial depth to human eyes.

Description

technical field [0001] The invention relates to a TV with glasses, in particular to a TV with transparent glasses that can watch external real scenes and virtual images at the same time. Background technique [0002] Most of the existing HMD (head mounted display, that is, head-mounted virtual display) products are opaque structures, and their structures are shown in Figure 1: [0003] The display device 1 such as LCD and OLED seen by the eyes 3 is imaged by the optical combination system 2, which is a virtual image, but the external real scene 4 cannot be viewed at the same time. [0004] In addition, there are currently some technologies that can realize simultaneous viewing of virtual images and external real scenes, and its structure is shown in Figure 2: the light splitting component 5 is also an image synthesis device, and display devices 1 such as LCD and OLED pass through spherical or aspheric reflectors. 6 The imaging is the virtual image seen by the eye 3, and the...

[0003] The display device 1 such as LCD and OLED seen by the eyes 3 is imaged by the optical combination system 2, which is a virtual image, but it cannot watch the real scene outside at the same time 4

[0004] In addition, there are currently some technologies that can realize simultaneous viewing of virtual images and external real scenes, and its structure is shown in Figure 2: the light splitting component 5 is also an image synthesis device, and display devices 1 such as LCD and OLED pass through spherical or aspheric reflectors. 6 The imaging is the virtual image seen by the eye 3, and the eye 3 can also see the external scene 4 at the same time, so that the purpose of viewing the virtual image and the external real scene at the same time can be realized, but the defect of this type of product lies in the field of view (magnification ) and the size of the volume are mutually restricted, or the video is small (low magnification), or the volume is large, and there is also the problem that the light intensity contrast is not easy to adjust. There is misalignment on the optical axis, which also affects the observation effect. Among them, the technical difficulty of adopting LOE display elements is high, the cost is relatively expensive, and the installation and adjustment are very difficult
