Abstract
The invention provides a composite film, a preparation method of the composite film and display equipment with the composite film. The composite film comprises a base material layer, an anti-ultraviolet coating and an anti-mist coating which are sequentially arranged in a stacking manner. The anti-ultraviolet coating and the anti-mist coating are arranged on one side of the base material layer, so that the sight cannot be influenced since the composite film surface is prevented from generating mist in a high-temperature humid environment, and the influence caused by ultraviolet rays can be effectively blocked, therefore, the aging speed of a film can be retarded, and a user is protected from ultraviolet ray injury. Furthermore, an adhesive layer, a release film and other functional layers can be arranged on the other side of the base material layer, so that the composite film has multiple functions, and thus the problem of single function of the composite film can be avoided.
