Embodiment Construction
[0020] Please refer to figure 1 and figure 2 , the backlight module 200 of the first embodiment of the present invention includes a fiber optic light guiding device 100 and an incident light source 210 . The optical fiber light guiding device 100 includes an optical fiber 10 . The diameter of the optical fiber 10 is 375 μm-500 μm. The optical fiber 10 includes a core 11 and a cladding 13 covering the core 11 and coaxial with the core 11 . The cladding layer 13 is made of polymer plastic. The diameter of the fiber core 11 is 125 μm-350 μm. The incident light source 210 is disposed near one end of the optical fiber 10 . The optical fiber 10 is provided with an inclined groove 15 towards the axial direction of the fiber core 11 by the outer wall 131 of the cladding 13, the groove 15 is arranged along the extending direction of the optical fiber 10, and the depth of the groove 15 is determined by One end close to the incident light source 210 of the optical fiber 10 gradual...
