Example Embodiment
[0028] Example 1
[0029] This embodiment provides a light source assembly for a backlight module, such as figure 2 As shown, the light source assembly includes a substrate 1 and an LED chip 2 encapsulated on the substrate 1. The LED chip 2 is provided with an optical conversion part 3, and the optical conversion part 3 is used to emit light from the LED chip 2 Monochromatic light is converted to white light. Specifically, the LED chip 2 may be a blue LED chip or an ultraviolet LED chip. The optical conversion part 3 includes a glass box body 3a and a phosphor or phosphor powder 3b encapsulated in the glass box body 3a.
[0030] Wherein, the phosphor or phosphor 3b can be a quantum dot material phosphor or phosphor, for example, it can be CdS, ZnS, PbS, CdSe, ZnSe, PbSe, CdTe, CdTeSe, InP, AgInS, CuInS, CuInSe One or more. The phosphor or phosphor may also be a conventional phosphor or phosphor, for example, it may be nitride, oxynitride, silicate, sulfide, fluoride material, e...
Example Embodiment
[0041] Example 2
[0042] This embodiment provides an edge-type backlight module, such as Figure 5 As shown, the backlight module includes a back plate 10 and a reflective sheet 20, a light guide plate 30 and an optical film set 40 which are sequentially arranged on the back plate 10. The backlight module also includes a light source assembly 50 which is arranged on the guide plate. Between the side of the light plate 30 and the side wall of the back plate 10. Among them, the light source assembly 50 adopts the light source assembly provided in the first embodiment. Refer to Figure 5 And combine figure 2 The light emitted by the LED chip 2 passes through the optical conversion part 3 and the filter film group 4 in sequence, and then enters the light guide plate 30, and then is emitted from the optical film group 40 above the light guide plate 30 and provided to the liquid crystal panel.
[0043] This embodiment also provides a direct type backlight module, such as Image 6 As s...
