Magnifying display device

Technical Field

The utility model relates to an enlarge display device, this indicates especially one kind can alleviate closely with excessive enlarged display device of eye to reduce visual fatigue, and can cooperate the demand in usage space, carry out the adjustment of position, utilize elasticity to support and fixed angle of adjustment, with rocking or the aversion of avoiding the image, and then reach the convenience that the visual effect was read to the preferred and closed.

Background

Medical science has demonstrated that, except 5% being a genetic factor, long-lived near-viewing is the leading cause of myopia, and we recall activities in daily life that are long-lived near-viewing? If the people do not really look near at the distance of more than two or three meters, people eat, wear clothes and the like, but do not stare for a long time, the main activities of looking near for a long time are reading and writing, and mobile phones, tablets and computers are additionally seen in recent years, the characters are the main key of the people entering civilized life, but the habits of the people using eyes are changed by the characters, and the people rarely look near for a long time before the characters do not exist, so that the myopia is a visual problem with extremely low occurrence probability for the ancient people before the civilized life, and the reason why the people with the myopia factors are not eliminated by the evolution theory is explained; after the characters are invented by human beings, myopia spreads in few literacy people, the myopia spreads with the popularization of education, and in recent years, the myopia of human beings gradually becomes a normal state because the smart phone and the tablet are almost one hand.

Ophthalmologists often recommend that a distance of 30 cm is kept when reading and writing, a distance of 60 cm is kept when reading and writing computers, the 30 cm and the 60 cm are not magic numbers, the distance is only required to be healthy for eyes, the user only needs to wear the computer, the user can see the computer only because of the limited operation distance and the size of the screen and the text patterns on the books is unclear, and therefore the proposal is provided, if the operation distance is not limited, for example, the computer uses a mouse, the screen can be farther than the books, the text patterns can be enlarged, and the farther the visual distance is, the more beneficial the eye health is, no matter the books or the computer screens are.

Shortening the time of seeing nearby objects means that the time of writing with power needs to be shortened, the risk of returning the school performance is possibly brought, and the children are easy to fall off without playing a mobile phone, so that the unrealistic difficulty exists; the selection which does not affect the performance of the school and leisure is to lengthen the visual distance of reading and writing, however, unless the characters and pictures are enlarged, the identification capability of eyes is reduced after the visual distance is increased, and the eyes are easy to be fatigued, moreover, the visual distance is increased beyond the range of two-hand operation, the natural visual distance limit of reading and writing is about 40 cm, and the visual distance is increased to fear that a new technology is needed to assist.

In order to solve the above problems, various solutions are proposed in the industry, and related technologies may refer to CN102692710B, CN203608282U, CN203057249U, CN201060318Y, and the antecedents of patents such as TW patent nos.
