Description

Luminescent photograph and the forming method

The present invention relates to a light-emitting photo, and more particularly, to produce a light-emitting photo by implementing an image using red, green, and blue phosphors used in cathode ray tubes or plasma display panels, and to form such a light-emitting photo The present invention relates to a light emitting photograph and a method of forming the same.

In general, photographs are taken of an image of a subject by using a manual or automatic camera, and an image photographed on a film is implemented by printing and developing on photo paper through a darkroom work, and the photographer is exposed to external light such as the sun or indoors. You will see the image reflected by the lamp.

In recent years, due to the development of optical technology, digital cameras that are convenient to use and semi-permanently store images of a subject instead of conventional manual or automatic cameras are in the spotlight. As is well known, this digital camera captures an image of a subject through a liquid crystal monitor installed in the camera.

The camera is electrically connected to a computer equipped with a software capable of imaging an image of a subject, and the photographer can view the image through a monitor. In addition, when the image of the subject is to be stored separately, it is also possible to print on the film sheet through the printer.

When using a digital camera like this, the image taken by the small liquid crystal monitor included in the camera can be immediately and easily identified, but ultimately, the image can be viewed through a computer equipped with a large monitor such as a cathode ray tube or a TFT-LCD. It must be reproduced.

Accordingly, in view of the fact that the image captured only through the above-described monitor can be implemented, it is impossible to view the picture in a situation where the monitor is not provided. In addition, even if such an image is printed on a film sheet through a printer, it is very inconvenient because the picture cannot be viewed in an environment where no external light is provided, that is, in a dark place.

The present invention was devised to solve the above problems, and prints an image of a subject photographed from a camera on a printer including red, green, and blue phosphors, and is easily prepared from a separately manufactured portable light source device. The object of the present invention is to provide a light emitting photograph and a method of forming the same, in which a structure and a method thereof allow a photographer to view an image.

Hereinafter, a light emitting photograph and a method of forming the same according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 shows an overall apparatus 10 for forming a luminescent picture according to an embodiment of the present invention.

Referring to the drawings, the device 10 is provided with a camera, for example, a digital camera 11 for capturing an image of a subject. As is well known, the digital camera 11 includes a small liquid crystal monitor capable of immediately checking the captured image, an optical finder that saves battery consumption, an automatic flash to freely photograph even in a dark night, and photographing. It is equipped with an internal and external memory for storing the captured image.

The digital camera 11 is electrically connected to a computer equipped with software capable of imaging an image of a subject in order to produce a captured image. The software installed in the main body 12 of the computer includes a color tone compensation program for matching the color of the image captured by the digital camera 11 with the color of the phosphor to be described later. It can be said to be preferable for. The computer main body 12 is connected to a monitor 13, such as a cathode ray tube or a TFT-LCD, to implement the captured image, and when the photographer needs to edit or modify the image, input means connected to the main body 12 such as a keyboard It is freely editable with (14) or the mouse (16).

When the image of the subject implemented from the monitor 13 is to be stored separately, the sheet for film is supplied through the printer 15 connected to the main body 12 to print the image and store the image as the photograph 100. Alternatively, it can be stored on a compact disc (CD) or DVD (DVD).

Here, according to the technical features of the present invention, the printed photo 100 can be easily seen by the photographer in an environment without external light through a separately provided light source device.

2 shows the overall process of producing such a luminescent picture.

Looking at the manufacturing process with reference to Figure 1 and 2 as follows.

First, an image of a subject to be photographed is photographed using the digital camera 11. (S1) Next, the camera 11 is connected to a computer to drive software having a color compensation program function provided in the main body 12. The video signal processing is performed.

In this case, in order to view the image of the light-emitting photo 100 without interference, as described above, the transmittance should be constant in the visible light region, and the color compensation program function installed in the computer main body 12 in the transmittance data of each wavelength region is provided. It is necessary to adjust the color by inputting it into the software.

Next, the image of the subject is checked through the monitor 13, and the editing process is performed as desired by the photographer using an input means such as the keyboard 14 or the mouse 15. Then, the sheet for film is supplied to the printer 15 connected to the main body 12, the image is transferred onto the sheet, and the photograph 100 is printed. (S3)

At the time of printing, the print 15 is not shown in the drawing, but as is well known, in the case of a color printer, a developer of red, green, blue, and black is stored in order to transfer an image onto the film sheet. Each developing apparatus is provided.

Here, according to a feature of the present invention, this developer uses a phosphor made of an inorganic light emitting material which does not occur in the visible light region in order to make the photograph 100 emit light. That is, red, green, and blue phosphors having a composition substantially similar to those used in display devices such as cathode ray tubes and plasma display panels are used.

If the wavelength of the light source that excites the phosphor to be described later is 365 nm, the red phosphor is Y ₂ O ₂ S: Eu, the green phosphor is Zn ₂ GeO ₄ : Mn, and the blue phosphor is Sr (PO _{4 6} Cl ₂ : Eu is a preferable example. In the case of black, graphite for black mattresses or other black pigments used in the display device may be used.

In the case of the phosphor used in the display device, it is manufactured by a flux-aided soilid state reaction and its average particle diameter reaches 3 to 10 micrometers. There is a possibility of blocking a plurality of nozzles provided in the printer 15.

Therefore, the red, green, and blue phosphors according to the present invention have fine particle diameters, can remove agglomeration, and also facilitate the dispersion of the phosphors so that reaggregation does not occur so that the above-mentioned flux-aided solid state reaction In other words, the spray pyrolysis method, the coprecipitation method, the sol-gel method, etc., may be manufactured using a process that can reduce the average particle size of the phosphor to sub-micron level. desirable.

As a result, the particle diameters of the red, green, and blue phosphors become fine, so that the nozzles provided in the print 15 are not blocked when sprayed. In addition, a head provided in the print 15, for example, an ink jet printer, to photograph the photograph 100, may spray the red, green, and blue phosphors by using a conventional bubble jet head. In other words, it can be said that the use of a head employing a piezo-electric material is advantageous for the spraying of the inorganic pigment.

On the other hand, without printing the photograph 100 using the print (15), using the photolithography method as in the display device, red, green, and blue phosphors are sequentially and repeatedly formed, such as application, development, exposure, formation, etc. Could be

Next, as shown in Figure 3, using a red, green, blue, black phosphor to coat the film 210 through which ultraviolet light is transmitted well on the film sheet 200 is printed image of the subject. (S5) The UV-transmitting film 210 is coated in this way to prevent the phosphor from being peeled off from the film sheet 210. This completes the picture 100.

After the photograph 100 having the UV-transmitting film 210 coated on the sheet 200 is completed, the photograph 100 is mounted on a light source device capable of excitation to see the photograph 100. (S5)

That is, as shown in FIG. 4, the light source device 40 is a light guide plate of a thin plate that provides a light source 41 and a path through which light passes so that light emitted from the light source 41 can excite a phosphor. 42 is provided.

The light source 41 is attached along one edge of the light guide plate 42, and a cold cathode fluorescent lamp (CCFL) 41a, an LED, or the like may be used for the light source 41. In addition, when the CCFL 41a is used, visible light in an unnecessary area may be emitted and the resolution of the photograph 100 may be impaired. Thus, a visible light blocking filter or an ultraviolet transmission cut-off may be used. It is preferable to employ a filter.

In addition, a reflecting plate 43 is attached to a lower surface of the light guide plate 42 to reflect light emitted from the light source 41 in an upward direction, and a reflecting plate 43 reflected from the reflecting plate 43 on an upper surface of the light guide plate 42. A diffuser plate 44 capable of diffusing light is provided.

Subsequently, the light source device 40 is operated to emit the photo 100. (S6)

That is, the photo 100 is mounted on the diffusion plate 44, the light is emitted from the light source 41, reflected and diffused, and emits phosphors. Thereby, it is possible to visually confirm the photograph 100. (S7)

At this time, the light source device 40 is designed to have a closed structure in order to prevent the light from the device 40 irradiated to the portion other than the picture 100, and also facilitate the picture 100 It can be said that it is desirable to be able to mount and detach or to make it portable for pocket.

As described above, the present invention may have a light emitting photograph and a method of forming the same as follows.

Transferring a developer containing red, green, and blue phosphors used in a display device such as a cathode ray tube or a plasma display panel to print an image of a subject on a film sheet, and then mount the image on a portable light source device. Since the image can be realized, the photographer can view the picture at any time regardless of the amount of external light without depending on external light such as sunlight or indoor lighting.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
