AI Technical Summary

Technical Problem

When the pattern units of the existing vehicle roof light guide film are lit, adjacent pattern units are partially illuminated, resulting in unclear pattern edges and affecting the display effect.

Method used

A light-blocking gap is set between adjacent light guide film display sections, and an opaque light-shielding layer is set on the surface and back of the light guide film. Combined with the light-transmitting area and the refractive layer, it is ensured that light only shines out from the designated area and prevents light from entering the adjacent display sections.

Benefits of technology

It improves the clarity and brightness of the pattern edges, enhances the display effect, avoids partial illumination of adjacent pattern units, and improves the overall display quality of the optical components.

Abstract

The present application discloses an optical trim for a vehicle and a vehicle. The optical trim comprises a first light guide film. The first light guide film comprises a plurality of display portions, each display portion having a first light exit surface and being provided with first pattern units within each display portion. Each first pattern unit is adapted to illuminate by light propagating within the corresponding display portion being emitted from the first light exit surface as the light passes through the first pattern unit, such that the optical trim displays a first pattern formed by one or more first pattern units. There is a first gap between adjacent display portions that blocks light. Light propagating within each display portion is prevented from being emitted into an adjacent display portion by the first gap adjacent to the display portion, such that first pattern units within adjacent display portions are not partially illuminated. Thus, the edges of the first pattern displayed by the optical trim are clear and sharp, and the display effect is better.
