Description

  The present invention relates to an enlarged display device, and more particularly, to an enlarged display device capable of mitigating excessive use of eyes at a short distance. To reduce visual fatigue and fill space usage, adjust the position and use elastic force to support and fix the adjustment angle to avoid image shaking and displacement. This improves the visual effect of reading and the convenience of storage.

  Genetic factors account for 5% of the major causes of myopia, and have been medically proven to be due to prolonged use of the eye at close distances. The use of eyes for a long time in a short distance in daily life is to watch television. However, if the viewing distance exceeds 2 meters or 3 meters, it cannot be said that the user is watching at a short distance. Eating and changing clothes need to be seen from a short distance, but it is not a long-term staring. The main activity of the eye at long distances is reading and writing. In recent years, the number of times of viewing mobile phones, tablets, and computers has increased. Although letters are the key to humanity's entry into civilized life, the use of letters has changed the habits of the human eye. Before humans were not invented, characters rarely saw things at short distances for long periods of time, so myopia was a very low incidence visual problem for ancient humans who did not have civilization. It is. This also explains why humans with myopic genes are not eliminated by evolution. After humans invented letters, myopia spread to a small number of non-literate people, and with the spread of education, myopia became common. In recent years, myopia in humans has become increasingly common, since most people have a smartphone or tablet.

  Ophthalmologists often recommend keeping a distance of 30 cm when reading and writing books and 60 cm when viewing a computer. 30cm and 60cm are not fixed numbers, but must be at this distance for healthy eyes. Also, the size of the screen and the text of the book are related, but there is such a proposal because the field of view is not clear if it is far away. If the distance can be adjusted without restrictions, such as with a computer using a mouse, the screen can be farther than a book and the text pattern can be enlarged. The longer the distance, whether a book or a computer screen, the better your eye health.

  Reducing the time to see nearby objects means that it is necessary to reduce the time spent writing, which can carry the risk of a decline in academic performance. It is also unrealistic and difficult to strip children's leisure of playing on mobile phones. The least impact on academic performance and leisure choices is to increase the visual distance between reading and writing. However, unless the font and the image are enlarged, the recognition ability of the eyes after the visual distance is increased is reduced, and the eyes are likely to be tired. Further, increasing the visual distance may exceed the range of the two-handed operation. Since the natural read and write distance limit is about 40 cm, extending the visual distance requires assistance using new technologies.

  To solve the above problems, the industry is continuously proposing various solutions. The related arts are described in Taiwan Patent Nos. Reference can be made to the specifications of Japanese Patent No. 298625, Chinese Patent Nos. 102692710B, 2036082282U, 20305572249U, and 2010060318Y.

  In the above-mentioned prior patents, some of the visual effects in implementation are not ideal, the main reason being related to the configuration of the optical components. Some of them are more visually effective, a typical representative being CN102692710B, a long distance reading system (hereinafter referred to as a reference) for controlling the development of myopia in adolescents. The optical path structure of this cited example, as shown in FIG. 1, receives a lens 62, one light source 63, a first plane mirror 64, and reflected light of the first plane mirror 64 above one bracket 61. The spectroscope 65 and one concave mirror 66 are arranged in order. The second plane mirror 67 and the screen 68 are arranged above the spectroscope 65, and the second plane mirror 67 receives the reflection line of the spectroscope 65, and the screen 68 receives the reflection line of the second plane mirror 67. The screen 68 is perpendicular to the reflected light on the front surface of the second plane mirror 67. On the center lines of the spectroscope 65 and the second plane mirror 67, a spectroscope 651 and a second plane mirror knob 671 are arranged, respectively. The spectroscope 651 and the second plane mirror knob 671 are used to adjust the mirror surface angle. By using the configuration of the optical path structure described above, it is possible to make people feel that characters and figures are 5 meters away, and to effectively reduce visual fatigue caused by excessive use of eyes at short distances. To reduce the progression of myopia. Although the reference can provide a better visual effect, it is a fixed-type device and lacks the retractable structure of the bracket, so it does not meet space requirements and cannot be adjusted for use. Therefore, storage and use are still inconvenient.
