A rapid and precision hot embossing of LGP micro-arch lens array inside core microgrooves: simulation and experiment

The hot embossing needs the heat preservation for precision micro-forming, thus leading to inefficiency. A hot embossing of polymer micro-arch lens array in half molten is proposed for the application of light guide plate (LGP). It only performs a thermal deformation for micron-scale surface layer to be squeezed into core microgrooves. First, the micro-optic illumination of LGP was analyzed to design the micro-arch lens array; then the...
