Description

System for improving vision including a 3D display device based on direct flotation {INTEGRAL FLOATING BASED THREE-DIMENSIONAL DISPLAY SYSTEM FOR IMPROVING SIGHT}

The present invention relates to a device, and more specifically, to a system for improving vision including a three-dimensional display device based on direct levitation.

There are approximately 4 billion people around the world with vision problems, including presbyopia (2 billion people), myopia (1.6 billion people), strabismus (260 million people), and amblyopia (180 million people). As we transition to an aging society, smart As the use of various digital devices such as phones and tablets becomes part of our daily lives, vision problems continue to increase. In relation to this, surgery (LASIK surgery/LASIK surgery) has been popularized as a way to solve vision problems, but many side effects from surgery have been reported, and the vision improved through surgery is also deteriorating over time.

The eye has a cornea and lens that act as a lens. The elements that determine vision are the cornea and lens. Light undergoes primary refraction in the cornea and secondary refraction occurs through the lens to form an image in the eye. Therefore, methods to restore vision include surgical keratectomy (LASIK) to restore the lens and vision function recovery exercises to develop the motor ability of the lens.

In the case of vision function restoration exercises, the ciliary muscle that holds the lens thickens or thins the lens according to distance control to control refractive power. Myopia, hyperopia, and astigmatism occur due to an imbalance in the control and strength of the ciliary muscle, so these lens control muscles must be used to control the lens. The training method is called ‘vision therapy’.

Although vision therapy is not well known in Korea, there are specialized vision therapy centers in the United States and Europe, and it is actually used by soldiers, athletes, and children with amblyopia for vision management, and a study showed that lens control significantly increased after training for a month. was also reported. However, the problem is that there is a lot of equipment that needs to be used for this, it is difficult to use without an expert, and it is expensive.

Even in Korea, many personalized products for eye function exercise and vision therapy are being developed and sold. These products have the advantage that users can easily use them at home without having to visit a specialized center such as a hospital or optician, check their vision every day, and improve their vision to some extent through training. However, as it is a generalized product that does not reflect individual characteristics, it is not only highly effective for some people, but most of them are in the form of an eye wearable (HMD) type, and are products based on stereoscopic technology, which allow real vision to work. Do not use all sensory elements.

When performing vision function recovery exercises tailored to individual characteristics, the expert checks the patient's progress and vision level, determines the characteristics of the lens and training range, performs training by converting the lens, and continuously adjusts the training range according to the results. It is common to do this, but this is difficult with portable equipment, and when experts manually train according to individual characteristics, all adjustments must be made manually, which limits the ability to receive professional services due to the high cost. In the case of the system, these professional services can be performed using automated technology, so many people with vision problems can receive highly efficient services at low cost.

In the case of existing eye training, individual training tools must be used for each training, so there is a disadvantage in that it costs a lot to purchase the entire tool.

Embodiments of the present invention seek to provide a system for improving vision including a three-dimensional display device based on direct levitation.

A system for improving vision according to an embodiment of the present invention includes a display panel; a lens array arranged to face the display panel; a plate on which an image emitted from the lens array is formed; and a control unit that changes the position of the image implemented on the display panel.

In addition, it may further include a distance adjusting unit capable of adjusting between the floating lens and the micro lens array.

Additionally, the distance adjusting unit may include a first fixing unit connected to the micro lens array; a second fixing part connected to the floating lens; and a driving unit connected to the first fixing part and the second fixing part to adjust the gap between the first fixing part and the second fixing part.

In addition, the plate is a half mirror vision improvement system.

In addition, it further includes a storage unit for storing a pickup image that is a source of an image implemented in the display panel, wherein the pickup image includes an element image array corresponding to the lens array; and an object area defined as an area within an outer boundary of the element image array, wherein the pickup image may be displayed as an object separated from a background area of the display panel area, which is the entire area of the display panel.

In addition, it further includes an image conversion unit that changes the size and position of the picked-up image, and the image conversion unit changes the size of the element images of the element image array based on the size change proportional value, and changes the size and position of the element image. The size of the object area can be changed by adjusting the spacing between the changed element images based on the size change proportional value.

Additionally, the image converter may change the size and position of the element image independently of the background area.
