The invention discloses a crystal film screen, a transparent substrate serves as a base, a layer of transparent double-sided film is arranged on the transparent substrate, a layer of transparent pressure-sensitive double-sided adhesive tape is arranged at the upper end of the transparent double-sided film, LED light source modules and LED lamp beads are arranged at the upper end of the transparent pressure-sensitive double-sided adhesive tape, and the LED light source modules and the LED lamp beads are attached to the transparent pressure-sensitive double-sided adhesive tape through high temperature. The upper ends of the LED light source modules and the LED lamp beads are further covered with a layer of transparent pressure-sensitive double-sided adhesive tape, a PTE transparent film is arranged between the LED light source modules and located between the upper layer of transparent pressure-sensitive double-sided adhesive tape and the lower layer of transparent pressure-sensitive double-sided adhesive tape, all parts of the crystal film screen are transparent and high in light transmittance, the thickness of the whole crystal film screen is only 1.5 mm, and the crystal film screen can be bent and cut and is not limited by the size. The crystal film screen is suitable for an arc-shaped structure, has ultra-light and ultra-thin properties, high transparency and the like, is suitable for large show windows, glass screen walls, glass handrails, glass doors, science and technology exhibition halls and the like, and has the characteristics of high light transmittance, convenience in installation, time saving and high integrity.
