Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the area of displaying a three-dimensional photograph for viewing for a substantially enhanced three-dimensional visual result and clarity.

2. Description of the Related Art

Studies show that people take and view two-dimensional photographs from prints or images displayed on computer monitor or video displaying or projecting electronic devices.

Studies also show that three-dimensional photographs can be taken with various methods. For example, it can be taken with a single camera with multiple lens or a single camera with a single len by shifting the camera's position or angle to shoot the object to obtain a stereovision effect. Some use multiple cameras shooting the object from different positions or angles. Yet some use graphic software to change a two-dimensional photograph into a three-dimensional photograph.

Studies also show that people generally do not use any three-dimensional photograph display panel to enhance the three-dimensional visual effect in a three-dimensional photograph and clarity when viewing a three-dimensional photograph.

Studies also show that front illumination on a three-dimensional photograph does not enhance the three-dimensional visual effect for a deeper depth effect or clarity.

Studies also show that back light using light bulb does not produce a uniform illumination over the entire surface of a three-dimensional photograph and has a short life span and generates too much heat.

Studies also show that back light using fluorescent lamp requires AC power. However, it produces too much of illumination for average viewing of a three-dimensional photograph, especially in a residential or office lighting environment and does not produce a uniform illumination over the entire surface of the three-dimensional photograph. Studies show that people tend not to look at a photograph for a long time when it is too bright.

Studies also show that back lit using Light Emitting Diode (LED) may or may not require power from an AC adapter. However, the cost of LED back lit light source is more expensive than that of illumination by fluorescent lamp or light bulb.

Studies also show that back light using Organic Light Emitting Diode (OLED) may or may not require power from AC adapter. Generally, the cost of OLED back lit light source is a lot more expensive and is not in mass production and readily available in the market at this time.

Studies show that consumers like to view three-dimensional photographs for more realistic three-dimensional visual result and satisfaction for its aesthetic and realistic appeal. Accordingly there is a great need for solutions to provide for an enhanced display system for viewing a three-dimensional photograph.

Studies also show that consumers like to view three-dimensional photographs without an AC adapter wiring attached to a device which displays the three-dimensional photograph. Accordingly, there is a great need for solutions to provide for an enhanced display system which back lit light source produces the right amount of illumination uniformly over the entire surface of a three-dimensional photograph yet requires only a small amount of battery voltage to eliminate the AC wiring for aesthetic purpose.

Studies show that consumers may like to display and view three-dimensional photographs on a flexible surface. Accordingly there is a great need for solutions powering a flexible light source.

Studies show that consumers may like to display and view three-dimensional photographs on a device that is thin, light weight, long life, economical with an efficient and uniform back lit light source. Accordingly, there is a great need for solutions to provide for an enhanced display system with said characteristics.

Studies show that there is a great need for solutions for a more uniform back lit light source giving an appropriate amount of illumination for the displaying and viewing of three-dimensional photographs for a substantially enhanced three-dimensional visual result and clarity.

In one embodiment, the display panel consists of a lenticular len or sheet and an electroluminescent lighting sheet and a three-dimensional photograph is sandwiched between said lenticular len and said electroluminescent lighting sheet with the lighting surface facing the back of said photograph. In one embodiment, the display panel is mounted on a photo mounting device, generally, a picture frame. In one embodiment, a piece of glass is placed directly over a layer or multiple layers of picture mat, which placed directly over said lenticular len. In one embodiment, the front of said three-dimensional photograph is laminated or mounted to the non-ribbed surface of said lenticular sheet. The layer or multiple layers of picture mat is to add more depth effect when viewing said three-dimensional photograph. In one embodiment, an inverter for the electroluminescent lighting sheet is placed behind said lighting sheet or the photo mounting device. In one embodiment, there is a compartment to house said inverter, said battery or rechargeable battery and said switch, which is installed behind electroluminescent lighting sheet or the photo mounting device. When said display system is hung on a wall or placed on a flat surface, such as a desk or a table, a three-dimensional photograph mounted on the photo mounting device, with the display panel facing forward, said three-dimensional photograph may be conveniently viewed by viewers in front of the displaying panel. For a uniform distribution of light, energy efficient consideration, cost consideration, light weight, thin, longevity, flexibility and appropriate amount of illumination, said display panel is normally back lit by an electroluminescent lighting sheet. In one embodiment, said three-dimensional photograph can be viewed with said back electroluminescent lighting source energized for a substantially enhanced three-dimensional visual effect for-added depth effect and clarity. In one embodiment, the display panel need not be energized for viewing. In one embodiment, said lenticular len, three-dimensional photograph and electroluminescent lighting sheet is backed by a support sheet made of various predetermined materials to hold and secure said display panel in place with said photo mounting device. In one embodiment, said photo mounting device has a hanging device and a support device in the rear for either hanging on a wall or placed steadily on a flat surface.
