BACKGROUND OF THE INVENTION

Field of the invention

The present invention relates to a display device for an enlarged display, in particular a display device for an enlarged display, with which an optimized projection light path is generated and the connection to a mobile phone, a computer or a TV screen, a screen image of the mobile phone, the computer or the television screen enlarged can be used to display a perfectly magnified image to users, effectively protecting the eyes from overexertion when viewing the image.

Description of the Related Art

Medical research has shown that, with the exception of 5% of a genetic predisposition, long-term viewing of a close-up image is the main cause of myopia. Among the activities that involve a close-up view of a close-up image, in everyday life, as is generally acknowledged, is television, but the distance between the viewer and the television screen is over two or three meters, so a television screen is not really off Close proximity is considered. When eating or dressing, food or garments are seen up close, but not over the long term. The activities, which are primarily close-up long-term, are reading books and writing, and in recent years have also seen screens of cell phones, tablets, and computers. Capturing texts is the key to human entry into civilized life, with eyes also changing with people's habits. Before using the script and consequently using texts, people hardly ever saw anything up close, so myopia is a visual problem that prehistoric people hardly suffered. This also explains why human short-sightedness did not die out during evolution. After the development of the script, myopia spread among the small number of people who could read and write. With the popularization of schooling and education, myopia has become an increasingly common problem. Since for some years practically everyone has a smartphone or a tablet computer, myopia has gradually become a normal phenomenon.

Ophthalmologists often advise people to keep a distance of 30 cm when reading or writing, and 60 cm when working on a computer; a distance of 30 cm or 60 cm is not mandatory, but the eyes are more comfortable. This recommendation also applies if the distance to operating is limited and the size of a text and images on a screen or in books is such that they are indistinct when viewed from a greater distance. However, if the distance to operate is not limited, for example, to a computer that is operated with a mouse, the screen may be farther away than a book and the text and images may be enlarged, generally the greater the distance When reading a book or watching a computer screen, the better the eyes are spared.

Shortening the viewing time of items at close range means shortening the time spent reading and writing, which can be a step backwards. By playing with smartphones children spend their free time, where unrealistic difficulties can occur. The only way to keep grades and free time from being adversely affected is to increase the visual distance between reading and writing. However, increasing the visual distance may decrease the perception of the eyes, causing the eyes to fatigue faster if the fonts and images under review are not enlarged. A greater visual distance may be greater than the reach of the hands, with the visual distance for reading and writing naturally limited to 40 cm. However, increasing the visual distance may be possible with new technologies.

In order to solve the above problems, various new technical solutions have been continuously proposed in the industry. These technical solutions are for example in the publications TW M 555049 . CN 203608282 U . TW I 518369 . CN 203057249 U . TW I 563361 . TW 298625 . TW 201608279 . CN 201060318 Y . TW M 541404 . TW M 535811 . TW M 536362 . TW M 548275 a typical approach in the document CN 203608282 U is disclosed (hereinafter referred to as cited reference). The 1 Fig. 10 shows a magnifying projector for a mobile phone screen as disclosed in the cited reference and composed of a projection mirror 51 and a magnifying glass 52. On the projection mirror 51, a mirror 510 is mounted, wherein the mirror 510 has a concave curvature, with which an image content of a mobile phone screen 53, which by the Magnifying glass 52 is projected. The projection mirror 51 may be combined with a tripod 511 to collapse and unfold it. A mirror 520 is mounted on the magnifying glass 52. The mirror 520 has a concave curvature with which the image content of the mobile phone screen 53 obtained from the projection mirror 51 is increased. The magnifying glass 52 may be combined with the stand 511, so that it can be folded and unfolded. The projection mirror 51 captures an image from the cell phone and reflects it to the magnifying glass 52, enlarging the image of the cell phone with the magnifying glass 52 to facilitate its viewing. Although the cited reference describes an enlargement and display of the image content of a mobile phone screen for easy viewing of the screen content, for this purpose, the angle and the distance of the projection mirror 51 and the magnifying glass 52 in use must be set manually, such a setting being the application for the User is difficult and time consuming. Further, the structure described in the reference is impractical because the optimized projection light path for viewing can not be obtained immediately. In addition, the construction described in the cited reference is limited to enlarging a mobile screen content and can not be used for a computer or a TV screen, so that the field of application is rather limited.
