Title: OPTICAL THIN FILM AND ELECTRONIC DEVICE COVER PLATE
Abstract:
Disclosed is an optical thin film, comprising: a carrier (20); and a micro-nano structure layer, one surface of the carrier (20) being provided with a channel (30), and a filler being provided in the channel (30) to form the micro-nano structure layer, wherein the micro-nano structure layer gradually changes visually in at least one direction. The gradual change involves realising a visual change in the micro-nano structural layer or producing the effect of a gradual change by adjusting the duty ratio of micro-nano structures, the depth of the channel, the cycle of the micro-nano structures or the density of the micro-nano structures. Further disclosed is an electronic device cover plate using the optical thin film.
