Embodiment approach 1
[0051] Such as figure 1 As shown, the manufacturing method of the liquid crystal lens provided in the embodiment of the present invention includes:
[0052] S1 is powered to drive the liquid crystal molecules in the liquid crystal layer to deflect to form a liquid crystal lens unit with a gradient refractive index;
[0053] S2 curing the liquid crystal lens unit meeting the preset conditions to form a liquid crystal lens.
[0054] Applying power to the liquid crystal layer to deflect the liquid crystal molecules in the liquid crystal layer to form a liquid crystal lens unit with a gradient refractive index. The liquid crystal lens manufacturing method provided by the embodiment of the present invention is based on the existing liquid crystal lens manufacturing process , increasing the power-on treatment of the liquid crystal layer to form a liquid crystal lens unit, performing curing treatment on the liquid crystal lens unit meeting the preset conditions, and completing the p...
Embodiment approach 2
[0085] The present invention also provides a liquid crystal lens, which is manufactured by the above-mentioned manufacturing method of the liquid crystal lens. The liquid crystal lens does not need to be made through a resin mold, which improves the yield rate of the product and reduces the preparation cost of the liquid crystal lens.
Embodiment approach 3
[0087] A schematic structural diagram of a detection device for a liquid crystal lens provided in an embodiment of the present invention. Such as Figure 7 and Figure 10 As shown, the detection device 2 of the liquid crystal lens includes: a laser 21, which is used to emit focused laser rays; a beam expander 22, which is arranged on one side of the laser 21, and is used to expand the beam radius of the laser rays; the first polarizer 23, opposite to the laser 21, it is arranged on one side of the beam expander 22, which is used to adjust the energy size of the expanded laser rays (making the maximum energy that can finally be detected by the image controller 28 slightly smaller than the image controller 28 can record The maximum value can be); the second polarizer 24 is arranged on one side of the first polarizer 23 opposite to the beam expander 22, and is used to control the polarization state of the laser ray after adjusting the energy, so that the polarization state of th...
