Abstract

The invention relates to the technical field of optical protection film, especially to an electrochromic privacy film and its preparation method. The electrochromic privacy film comprises a film protection layer, a first adhesive layer, a hardening layer, a first main film layer, a shutter layer, a second main film layer, a second adhesive layer and a stripping layer which are successively arranged from top to bottom. An electrode is connected between the upper surface and the lower surface of the shutter layer. The electrochromic privacy film has high light transmittance and adjustability of the privacy function. In an easy-peeping environment, by starting an electrode switch, the protective film can undergo electrochromism to have the privacy function. In a safe environment, by shutting the electrode, the privacy function can be cancelled.

Description

technical field [0001] The invention relates to the technical field of optical protection films, in particular to an electric anti-peeping film and a preparation method thereof. Background technique [0002] With the rapid development of electronic products, more and more electronics can be accepted by ordinary consumers, which promotes interpersonal communication, improves work efficiency, and provides more entertainment items. However, people use electronic products At the same time, due to the large viewing angle of the screen, some confidential information, account numbers, passwords, etc., are easy to cause peeping and leakage of personal privacy. Therefore, it is even more important to protect personal privacy information in public places. [0003] Although there are anti-spy films currently on the market, which protect personal privacy to a certain extent, such anti-spy films generally have defects such as poor light transmittance and inability to adjust the anti-spy...
