Abstract A method for fabricating a microlens array composite optical film by a seamless roller mold of self-assembly is presented. The roller with a lot of random cavities is used to produce a polyethylene terephthalate (PET) composite optical film with 3D random microlens arrays using the ultraviolet (UV) roll-to-roll printing. The luminance gain and haze are 1.247 and 86 %, respectively, giving the PET composite optical film the properties of a brightness enhancement film and a diffuser. Solid glass beads (SBs) are used for parameter testing for self-assembly. Then, 3 M glass bubble beads (BBs) are used to fabricate a seamless roller mold. The optimal parameters of the self-assembly process for the SB are a coating speed of 135 mm/h with a 39 % volume ratio, and those for the BB are a coating speed of 30 mm/h with a 3 % volume ratio. Finally, the PET optical film is used in the green energy lighting testing of a commercial bicycle light-emitting diode (LED). The results show increased lighting angle and light uniformity, making it similar to traditional tungsten light. Keywords Self-assembly . Optical film . Roll-to-roll process . Spherical microlens .

1 Introduction The purpose of the current study is to fabricate a random microspherical array structure on an optical film by an ultraviolet (UV) roll-to-roll technology [1]. Microspherical arrays are a very important structure because they act as a diffuser and can enhance the functions of optical film [2]. In the rollQ.
