Field of the Invention The present invention relates to a light source module, and more particularly to a light source module having a shared wavelength conversion structure and a method thereof. [Prior Art] The light source applied to a display has a tendency to become more and more flat and has a large light-emitting area. A planar light source having a large light-emitting area is also important for a light source applied to a large-sized flat-panel liquid crystal display. In the prior art, a light source for providing visible light by means of energy/wavelength conversion includes a cold cathode fluorescent lamp (CCFL) and an external electrode fluorescent fluorescent lamp (External Electrode Fluorescent Lamp' EEFL). Light-emitting diodes (LEDs), carbon nanotubes (CNTs), flat fluorescent tubes, and organic light-emitting diode displays (OLEDs). Providing a large area of lighting, which will have certain shortcomings: "Mura effect" is one of the issues to be considered. In the description # of the present invention, the "❿ effect" is a phenomenon in which all brightness is uneven, especially when a large-sized illumination source composed of a plurality of light-emitting units is used, if the number of the above-mentioned hair-emitting and germanium units is insufficient, The distance between the light-emitting units is too large, or the light-emitting unit is in the vicinity of the display area of the sin, which will highlight the point/line light source characteristics of the conventional light source, resulting in uneven illumination, and the mura effect will become more serious. In the technology, the technology for producing a large-sized visible light source has not been completed. "Because of the limitations in mass production itself, it is impossible to convert a large area of light in an easy and inexpensive manner. One of the two efficient lighting methods is the light-emitting diode, which not only has the low-power 200935142 rate consumption characteristics, but also is environmentally friendly. However, in today's technology, all of the LED dies have only one die assembled therein. It is not well suited for large size lighting. Accordingly, the present invention provides a light source having a plurality of die packages. However, the inventors of the present invention have found that a light source having multiple grains will produce a mura effect. Based on the above, there is an urgent need for a multi-die module having a shared mura-eliminating structure. SUMMARY OF THE INVENTION Based on the above-described deficiencies, it is an object of the present invention to provide a light source module ′ having a shared wavelength conversion structure to improve the aforementioned problems. The light source module includes: a frame; a plurality of LEDs (Light Emitting Diode) die disposed in the frame; and a shared wavelength conversion structure disposed on the frame for reducing, "mura * And converting a first wavelength of light emitted by the LED die to a second wavelength. Another object of the present invention is to provide a method of fabricating a light source module having a shared wavelength conversion structure, comprising: providing a frame; arranging a plurality of ❹LED dies in the frame; and configuring-sharing the wavelength conversion structure in the frame Above the body, and overlying the plurality of LED dies to reduce the rmura effect" and converting a first wavelength of light emitted by the LED dies into a second wavelength. The co-dry wavelength conversion structure of the present invention has a transparent substrate and a wavelength conversion layer formed on the transparent substrate. The wavelength conversion structure described above is combined with a light source to improve the unevenness of light divergence and to reduce the 眶a effect. The present invention can improve the planar light source composed of a plurality of light-emitting elements, the brightness of which is not uniform, and provides a large-area visible light source. Furthermore, 200935142 The invention also simplifies the process of coating the phosphor on the substrate. The light source of the present invention can be more easily applied to a backlight module of a large-sized display panel by a simple method. The inventors of the present invention can understand the spirit of the invention and other objects of the invention after reading the embodiments described below. [Embodiment] The present invention will be described in detail with reference to the preferred embodiments thereof and the accompanying drawings. It should be understood that all of the preferred embodiments of the present invention are intended to be illustrative only and not limiting. Therefore, the invention may be applied to other embodiments in addition to the preferred embodiments described herein. The invention is not limited to any embodiment, which is to be construed as the scope of the appended claims and their equivalents. In addition, the components of different components do not clearly show their proportions. The size of the relevant component: it can be increased, the unimportant part will not be green, to clearly articulate the content of the invention' and emphasize the focus of the invention. The present invention configures a shared wavelength conversion structure on a plurality of LED crystal grains to improve the uniformity of the light and to reduce the mura effect produced by the precursors of the plurality of light-emitting elements. Furthermore, since the glory powder coating is applied to the substrate of the co-dry wavelength conversion structure instead of being individually coated on a single particle, the present invention simplifies the process and saves costs. The invention: the wavelength conversion structure can enhance the planar light composed of the plurality of light-emitting elements: the light is hooked and selectively provides the desired (four) domain. Therefore, the wave=changing layer is separated from the light source, and the above-mentioned missing technology can be effectively eliminated. 200935142 The present invention discloses a structure having phosphor powder or other materials to increase the uniformity of light and reduce the mura effect. The above structure can be used for wavelength conversion under a light source structure composed of multiple crystal grains. A detailed preferred embodiment will be described below. In the present invention, "UVC" means an ultraviolet ray having a wavelength of not more than 28 Å. The wavelength is preferably between 200 nm and 280 nm, especially in the range between 25 Å nm and 260 nm. The optimum wavelength of the above UVC is 253.7 nm. "UVB" refers to ultraviolet light having a wavelength between 280 nm and 32 〇 nm; and "UVA" is ultraviolet light having a wavelength ranging from 32 〇 nin to 4 〇〇 nm. "Materials that can be excited by ultraviolet light (or uvc, uvA, uvB)" are materials that absorb ultraviolet light (or uvc, UVA, UVB) and emit visible light when exposed to ultraviolet light (or UVc, UVA, UVB). In order to achieve conversion wavelengths and to enhance light uniformity and thereby reduce mura effects, in accordance with a preferred embodiment, the present invention provides a shared wavelength conversion structure, as shown in Figure 1A. Shown in Figure 1A. ,···# Each of them represents a different color of phosphor powder. In a preferred embodiment, the material of the wavelength conversion structure comprises a phosphor powder, a photoluminescent layer, a fluorescent color-conversion media, an organic complex material, and a luminescent pigment. (luminescent pigments), quantum dot-based materials, quantum wire-based materials, quantum well materials, and combinations of the above. The shared wavelength conversion structure 102 includes a transparent substrate 1021 and a wavelength conversion layer 1023. The wavelength conversion layer 1023 is disposed on the transparent substrate 1021 and has a phosphor powder and an anti-uvc adhesive material which can be excited by UVC 200935142. The thickness of the shared wavelength conversion layer 1 〇 23 is between about two and ten times the average particle size of the phosphor powder. The amount of phosphor in the wavelength conversion layer 1023 must meet at least one of the following conditions: (1) The phosphor powder must account for 30% to 80% of the total volume of the shared wavelength conversion layer (fluorescent powder and anti-uvc adhesive material). (ii) The specific gravity of the phosphor powder and the adherent material is about 1:1 to 2:1. Any fluorescent powder suitable for excitation by UVC can be applied to the ❹ shared wavelength conversion layer of the present invention. For example (but not limited to), it is selected from the group consisting of: europium doped yttrium oxide, terbium doped cerium lanthanum phosphate-doped lanthanum aluminum lanthanum (eur〇piumd〇pedbar^m magnesium aiuminum oxide) and combinations of the above materials Any commercially available product can also be used as a phosphor powder as a wavelength conversion layer. The adhesive material used in the wavelength conversion layer can adhere the phosphor powder to form a wavelength conversion layer. The adhesive material is usually selected from macromolecular adhesive materials. However, when the above wavelength conversion layer is in contact with UVC, the anti-UVc adhesion material can preferably prevent the adhesion from being lowered due to the excitation process. The transparent sheet can also be used as a transparent substrate for the above-described shared wavelength conversion structure. The transparent substrate may be an elastic film, in particular an elastic film made of a polymer, to facilitate mass production using roll t〇 r〇 11 c〇ating. The elastic film system is preferably transparent or highly transparent. For example (but not limited to) 'transparent substrate can be a thin plate made of the following materials: glass, quartz, polymethylmethacrylate (PMMA), polystyrene 200935142 (polystyrene, PS), methyl methacrylate -co-styrene (MS) or polycarbonate (PC). Alternatively, a light transmissive fiber fabric (generally made of glass) can be used as the glass substrate. A synthetic material layer made of two or more of the above films or sheets can be suitably used as the transparent substrate of the present invention. A pressure sensitive polymer adhesive can be used to bond the film or sheet described above. The shared wavelength conversion structure can be applied to a light emitting module. In this embodiment, an optical enhancement structure, e.g., a germanium or a special structure, may be formed on the side of the transparent substrate facing the wavelength conversion layer to further enhance the optical effect. Optionally, to enhance brightness or polarization effects, the wavelength conversion structure may further comprise any suitable optical component, such as an optical film such as a diffusion plate, a diffusion film, a brightness enhancement film, a reflection. A type of dual brightness enhancement film, a diamond lens, a polarizer, a lenticular film, and/or a combination thereof.
