However, for the existing anti-spy film material, the light emitted from the backlight will be divided into two parts, one part is emitted to the surface of the module, that is, the part visible to the human eye, and the other part is protected by the anti-peep function in the anti-spy film material. Material absorption, in view of the loss of part of the light being reflected and absorbed, the existing anti-peeping means will reduce the brightness of the module by about 40%, resulting in failure to meet customer needs.
