New Description: [New Technology Field] This creation is to provide a light source module and a liquid crystal panel combination device, especially the white light backlight of the liquid crystal panel has better color rendering. [Prior Art] According to the combination of the LCD panel and the backlight module, the typical structure is the new type certificate of Taiwan, No. 2 4 5 4 4 8 "Light source module for liquid crystal display". The polar system consists of ultraviolet (U v) L ED and red, blue and green (r, β, G) phosphors. The disadvantage is that the ultraviolet light will cause damage to the epoxy resin structure which is currently used, so that the final white light will cause light attenuation, and the brightness of the white light is not strong, especially the coating layer of the case is composed of red, green and blue. The color of the work powder is mixed, and the ratio of the three pigments and the process are difficult to control, which is one of its shortcomings. In addition, the fifth item of Shen Shiyue's patent scope claims that the light-emitting diode is a blue LED, the light powder is red, and the green fluorescent material f, but the red fluorescent powder and the green luminous powder are mixed. The process is difficult to control so that the uniformity of the mixed light (i.e., white light) is difficult to control, and the color rendering of the white light appearing on the liquid crystal panel is not good. Taiwan's new certificate No. M2 5 1 1 4 3 "Light source device for liquid crystal screen" uses a blue or UV light with a wavelength between 2 〇 2 nm and 5 〇〇 (10) as a single light source, but The light source lacks the red light spectrum portion, so the white light (ie, mixed light) mixed by the excited fluorescent plate has poor color and uniformity, and the white light defined by the human eye is impure. The invention of Taiwan Patent No. I 2 2 8 8 3 7 illuminating device is a white light emitting diode which utilizes two light-emitting dies of blue · M285713 • i light and red light ( LED) as two light sources, the phosphor layer is glued to the blue crystal grains and the red crystal grains, and the fluorescent layer is excited by the blue light source to emit a green light, which is mixed with blue and red light to form white light. The case effectively overcomes the problem that the ratio of the different color phosphor powders in the aforementioned patents and the process are difficult to control, that is, the red phosphor is used to replace the conventional red phosphor, and the phosphorescent layer material is further made. For the design of a single color material, the problem of different color mixing ratios and difficult process control can be solved, and the single excitation wavelength of the light (ie, the wavelength of green light) can be further controlled. Furthermore, the case utilizes red. The red light emitted by the light LED is mixed with the three colors of excitation light and blue light, and the obtained white light color rendering property is better. However, the embodiment of the case is limited to the new design of the white light emitting diode, and there is no expanded combination of the combination device used for the liquid crystal panel and the backlight module. [New content] The main purpose of this creation is to provide a combination of a light source module and a liquid crystal panel 10, and to display the transmitted backlight white light, which is easy to control color rendering and uniformity, and good color rendering and uniformity. . A further object of the present invention is to provide a combination of a light source module and a liquid crystal panel. The phosphor layer used in the backlight module is a uniform light material, so that the wavelength of the excitation light can be easily controlled to achieve the backlight of the liquid crystal panel. The color rendering and uniformity of white light are easy to control. A further object of the present invention is to provide a combination of a light source module and a liquid crystal panel, which can be easily replaced by a light diffusing sheet coated with a fluorescent layer to achieve replacement. -M285713 八, this creation, including: As shown in Figure 1, 2, 3, 4, 5, 6 and 7, is to provide a light source module and a liquid crystal panel combined with a liquid crystal panel 10 bottom surface The ii device has a transparent light diffusing sheet 2; and the light source module 20 includes:

The ninth diagram indicates that the blue crystal grains 3 2 and the red crystal grains 34 and the fluorescent layer 40 are covered by the bulb-type transparent glue 45, which forms the mixed white light W and is transmitted by the light diffusion sheet 12 . As shown in Fig. 12, it refers to the upper surface of the light diffusing film 12, which can be added with a light-increasing film 125 or a brightening film according to the designer's needs, which is also an effective implementation of the present invention. example. (2) The main feature of this case is that the backlight of the liquid crystal panel 1 is applied with blue crystal 3 2 and red crystal 3 4, and the two are independent chips (Chip) to further select the fluorescent layer 40. For a single color fluorescent material, such as YAG: Ce3+ or YAG: EU2+/3+ or YAG: Tb3+, which are all of the same color, one or two or three combinations of materials. Therefore, there is no need to consider the problem of mixing ratios with other different color phosphors. Therefore, the photoluminescence color of the phosphor layer 40 of a material is defined as green, and its wavelength is between 500 nm and 50.7 nm. Therefore, the wavelength of the excitation light G (i.e., defined as green) generated when the phosphor layer 40 is induced by the blue light B is easily controlled. The red light crystal 3 4 is a light emitting diode, and the blue light crystal 32 is also a light emitting diode. By controlling the circuit, the red light crystal 34 and the blue light crystal 3 2 can be controlled to emit light and the luminous intensity. Synchronize the starting point of the white color of the color. (3) As shown in Figures 3, 4, 5, 6, and 7 of the light diffusing sheet 2, the phosphor layer 40 deteriorates due to long-term light and electricity, making the white light...

The glue layer 1 2 4 is peeled off from the circuit board 2 1 , and the new light expansion sheet 1 2 containing the fluorescent layer 40 is attached to the circuit board 2 1 by the adhesive layer 1 2 4 thereof. , the purpose of the replacement of the old, so that the white light W / ochre of the LCD panel work is to maintain the state of the new product. In summary, the purpose of the present invention has been achieved, and the new, progressive and industrial availability has been achieved, and the applicant submits an application according to law.
