The invention discloses a light and shadow overlapped automobile interior trim part and a preparation method thereof. The interior trim part comprises a transparent part body and a light-emitting structure. The light-emitting structure comprises a first PC membrane, a contour layer, a color layer, a diffusion sheet, a second PC membrane, a side-in type Mini LED light bar and a reflection sheet. A contour layer is arranged on the back face of the first PC membrane, a color layer is arranged on the back face of the contour layer, and the diffusion sheet is arranged between the color layer and the second PC membrane. The side surface of the second PC diaphragm is provided with a side-in Mini LED light bar, the lower surface is printed with dots or dots are formed by laser dotting, and the back surface is provided with a reflector plate; the side-in type Mini LED light bar comprises a flexible substrate, a Mini LED blue light wafer and an optical sealing glue layer. Wherein the optical sealing glue layer is used for packaging the Mini LED blue light wafer in the optical sealing glue layer, a red quantum dot crystal, a green quantum dot crystal and a diffusant are arranged in the optical sealing glue layer, and the Mini LED blue light wafer excites the red quantum dot crystal and the green quantum dot crystal to form white light. The interior trim part finally achieves about 110% NTSC color gamut coverage rate, and the color gamut performance is improved by more than 50% compared with a traditional scheme.
