Description

Technical Field

[0001] This utility model relates to the field of vision testing equipment technology, and in particular to a far-image display device. Background Technology

[0002] Multimedia devices, especially those carrying video or images, and even text, are widely used in daily life. However, excessive use can lead to eye strain and, in some cases, myopia. This is particularly true for children and teenagers, whose vision impairment has a significant impact on their daily lives. Therefore, telephoto display devices have emerged to help improve the eyesight of young people. These devices can display upright, magnified, and distant virtual images. The curved mirrors used in these devices are expensive and require strict manufacturing processes, resulting in precise optical components. Even slight changes can affect the final image quality.

[0003] In the existing technology, the beam splitter, curved reflector and frame involved in the far-image display are formed as a whole. That is, the beam splitter is one side of this whole, and the back side of the curved reflector is also one side of this whole. This whole is directly set in the housing, which exposes more of the curved reflector, making it more likely to be damaged by the outside world. This will seriously affect the user experience and even shorten the service life of the far-image display device.

[0004] Therefore, it is necessary to provide a remote image display device to solve the above-mentioned technical problems. Utility Model Content
