Abstract: The present application discloses a lens assembly, a display module, and an electronic device. The lens assembly includes a first lens including a first surface and an opposite second surface and a semi-transmissive and semi-reflective film arranged on the first surface. The semi-transmissive and semi-reflective film includes a modulation film layer and a medium film layer, the modulation film layer being arranged on the first surface of the first lens, and the medium film layer being arranged on a side of the modulation film layer away from the first lens. The medium film layer and the modulation film layer are configured to cooperatively adjust a refractive index of the semi-transmissive and semi-reflective film, so as to allow circularly polarized light incident on the semi-transmissive and semi-reflective film at different incident angles to remain as the circularly polarized light after entering the first lens.

Abstract: An optical structure and a display device are provided. The optical structure includes a lens, a transflective film, a phase retardation film and a reflective polarizing film. The lens includes a first surface and a second surface which are non-planar surfaces; the transflective film is located at a side of the first surface away from the second surface; the phase retardation film and the reflective polarizing film are located between the phase retardation film and the second surface. The optical structure further includes a phase compensation structure located between the transflective film and the second surface. The phase compensation structure includes first light-transmitting layers and second light-transmitting layers which are alternately arranged and equal in number, a refractive index of the first light-transmitting layer is greater than that of the second light-transmitting layer; and the first light-transmitting layer is attached with the phase retardation film.
