[0044] In an embodiment of the present invention, further, a method for preparing a novel quantum dot light guide plate backlight module structure is characterized in that: if the polymer material of the material is a thermoplastic polymer material, the specific steps include:
[0045] Step 1: Put the polymer material in an oven at 70-80°C and bake for 3-4 hours to remove the moisture in the polymer material;
[0046] Step 2: Weigh the red and green quantum dots and the baked polymer material in proportion, then disperse the quantum dots in an organic solvent, then pour the dispersed quantum dot solution into the polymer material, and mix well to form a quantum dot Point polymer mixture;
[0047] Step 3: Put the quantum dot polymer mixture into the feeding port of the injection molding instrument for heating to form a quantum dot polymer melt;
[0048] Step 4: Inject the quantum dot polymer melt into the airtight mold, cool down to 40-50°C and open the mold after it is formed...
Embodiment 1
[0051] (1) Weigh a certain mass of styrene, weigh 0.15% of the weight of styrene quantum dots, wherein the ratio of red quantum dots to green quantum dots is 1:10, weigh 0.6% of the weight of styrene n-hexane solvent, weighed benzoyl peroxide whose weight is 0.25% of styrene weight.
[0052] (2) Disperse the quantum dots in n-hexane solvent, ultrasonically oscillate for 15 minutes to fully disperse them in the solvent, add styrene to the quantum dot solution, and stir well to make the quantum dots evenly dispersed in the styrene to form quantum dots monomer solution.
[0053] (3) Add benzoyl peroxide to the quantum dot monomer solution prepared in step 2 and ultrasonically oscillate to make it fully dissolved, then reflux the water bath at 90°C to carry out pre-polymerization. Observe the change of the solution every 5 minutes. When the viscosity of the solution gradually increases to form a viscous thin slurry, the solution is yellow and thick. Cool it to room temperature an...
