Abstract: A glue spreading system includes a spreading unit and a control unit. The spreading unit includes a primary pressing roller and a spreading roller. The spreading roller is adjacent to the primary pressing roller. A thin film transports between the primary pressing roller and the spreading roller. The spreading roller is configured for spreading a glue layer on the thin film.

The control unit is configured for detecting the actual thickness of the glue layer, and compares the actual thickness with a preset thickness. The control unit controls the pressure of the primary pressing roller applying on the spreading roller according to thickness differences between the actual thickness and the preset thickness.

Abstract: In a method for manufacturing an integral imaging device, a layer of curable adhesive is first applied on a flexible substrate and half cured such that the curable adhesive is solidified but is capable of deforming under external forces. Then the curable adhesive is printed into a lenticular lens having a predetermined shape and size using a roll-to-roll processing device and fully cured such that the curable adhesive is capable of withstanding external forces to hold the predetermined shape and size. Last, a light emitting diode display is applied on the flexible substrate opposite to the lenticular lens such that an image plane of the light emitting diode display coincides with a focal plane of the lenticular lens.
