[0003] A liquid crystal display requires polarized light as a light source. In the manufacturing process of the liquid crystal display, a polarizing plate is generally disposed between the light emitting diode light source and the liquid crystal panel, thereby converting the light emitted by the light emitting diode into polarized light. However, the polarizing plate usually allows the polarized light to be passed through, and the polarized light which is not required to be absorbed by the polarizing plate is, and thus, the light-emitting efficiency of the liquid crystal display is greatly lowered. Therefore, in the prior art, a polarized light-emitting diode having a single-sided light emission has appeared, which uses a special polarizing layer to derive the polarized light required, reflects the non-required polarized light, and is matched with the polarized light conversion layer, which will be non-required. The polarized light is converted to the required polarized light to enhance the light extraction efficiency. [0004] However, in the above-mentioned polarization light-emitting diode light source, only one side of the light source can be emitted, and the direction of the polarized light that is emitted does not have diversity, and cannot satisfy other multi-component applications, such as the field shape of the modulated light-emitting diode.

Referring to FIG. 6 and FIG. 7 together, the third embodiment of the present invention provides a light-emitting diode light source 3〇〇, and the structure thereof is similar to that of the light-emitting diode light source 200 provided in the second embodiment. It is that the shape of the plurality of protrusions 312 included in the bracket 310 is different. Of course, the plurality of protrusions 312 can be designed in any shape according to actual needs, except as shown in this embodiment. [0025] In the technical solution, the bearing surface of the bracket is set as a curved surface, and the plurality of light emitting elements are sealed in the mounting groove opened by the self-supporting surface, so that the light emitting diode light source has multiple light emitting surfaces, thereby having different light distribution curves. A plurality of light-emitting diodes of different colors can form different color space distributions. In addition, the light emitted from the plurality of light-emitting units in the present invention is a polarized light having a single polarization state, and can be used as a backlight of the liquid crystal display device. Each light-emitting unit straw is provided with a polarization conversion layer and a reflective polarization layer, so that the undesired polarization light is reflected by the reflective polarization layer, and then converted into polarized light requiring polarization state through the polarization conversion layer, and then subjected to reflective polarization. The layer emerges. Thus, the light extraction efficiency of the light source can be improved. In addition, those skilled in the art can make other changes within the spirit of the present invention for use in the design of the present invention as long as it does not have the technical effects of the invention. All changes made in accordance with the spirit of the invention are intended to be included within the scope of the invention as claimed. [0027] In summary, the present invention has indeed met the requirements of the invention patent, and the patent is filed according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
