Abstract
The preparing method of UV resin compound optical film (COF) by curing under the help of mold has been first proposed in the paper. The simulation results indicate that the theoretical values of the full width at half maximum (FWHM) for the horizontal and vertical direction are 14 degrees and 24 degrees, respectively. Then, the collimated ultraviolet light has been used to prepare the UV resin COF sample with the help of the mold. The experiment results claim the FWHMs of the horizontal and vertical direction for the sample are 16 degrees and 25 degrees when the uniformity is 86%, and it is consistent with the simulation results. The performance parameters in the BLM with COF fabricated are greater than those in the traditional one. Therefore, the COF can provide a collimated uniform plane light source and the new fabrication method is effective.
