Mobile phone film

Abstract

The invention discloses a mobile phone film, belongs to the field of electronic materials, and aims to reduce the brightness of a mobile phone screen through light absorption and storage functions ofthe mobile phone film without influencing rest of others. The fluorescent function of the mobile phone film is used for shining, and the use of a user is not hindered. The technical scheme relates toa mobile phone film which is formed by processing an alkaline earth aluminate silicate material activated by rare earth elements and is non-toxic, free of radiation and stable in chemical performance.The design has the characteristics that the light absorbing, storing and emitting process can be circulated infinitely and used permanently and the like.

Description

technical field [0001] The invention belongs to the field of electronic materials, and particularly relates to a mobile phone film. Background technique [0002] It is very inconvenient to use the high brightness of the mobile phone screen at night, which affects the rest of others. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a mobile phone film, so as to reduce the brightness of the mobile phone screen at night without affecting the use of the user. [0004] In order to solve the above-mentioned technical problems, the technical scheme adopted in the present invention is: an alkaline earth aluminate silicate material activated by rare earth elements is processed into a low transmittance mobile phone luminous film. [0005] The light absorption and light storage function of the mobile phone film reduces the brightness of the mobile phone screen without affecting the rest of others; the fluorescent function of...
