Quantum dot backlight module

A quantum dot backlight module comprises a diffusion piece and a light source group opposite to a surface of the diffusion piece, wherein the light source group includes a printed circuit board, a plurality of LEDs operably installed on the printed circuit board via a support, and a plurality of optical lenses on the printed circuit board and covering the corresponding LEDs, the backlight module also comprises quantum dot films attached to the outer surfaces of the optical lenses such taht the light emitted by the LEDs excites a quantum dot material in the quantum dot films. 种量子点背光模块，包含扩散片及与该扩散片的表面相对的光源组，其中，该光源组包括印刷电路板、多个经由支架可运作地安装于该印刷电路板上的发光二极管、及多个设置在该印刷电路板上且覆盖对应的发光二极管的光学透镜，该背光模块还包含：量子点薄膜，该量子点薄膜是贴附在该光学透镜的外侧表面上，以致于从发光二极管发出的光线激发量子点薄膜中的量子点材料。
