Abstract

The invention discloses a light emitting device, a light emitting system, a vehicle, a parameter determination method, an electronic apparatus, and a non-volatile computer readable storage medium. The light-emitting device comprises a light-emitting part and an optical module, the optical module and the light-emitting part are arranged in a stacked mode, the optical module comprises a light uniformizing part, the light uniformizing part at least comprises a diffusion layer and a polarization layer, and the polarization layer and the diffusion layer are arranged in a stacked mode. When passing through the optical module, the light emitted by the light-emitting part is at least scattered by the diffusion layer, so that the uniformity of the light emitted by the optical module and even the light emitted by the light-emitting device is high, and the conditions of light spots and uneven brightness are avoided. The arrangement of the polarization layer can reduce stray light and emission of light in a non-specific polarization direction, so that the light emitting effect of the light emitting device is improved. Thus, through the arrangement of the diffusion layer and the polarization layer, lens lines of the light emitting device can be avoided, the light emitting effect of the light emitting device is improved, and the visual experience of a user is improved.
