An automotive apparatus, comprising:

• a display device, having a display region and a peripheral region surrounding the display region, the display device comprising:
• a display panel, comprising a light-emitting surface, wherein the display panel is adapted to emit a display information from the light-emitting surface;
• a substrate, located on the light-emitting surface of the display panel;
• at least one illumination light emitter, configured to emit an illumination light;
• an illumination light penetrable module, comprising a light guide layer, wherein the light guide layer is disposed on a plane defined by a first direction and a second direction, and the illumination light is adapted to enter the light guide layer via at least one side of the light guide layer;
• and
• a first illumination light reflective layer, disposed on the light guide layer along a stacking direction and disposed in the peripheral region, wherein the illumination light penetrates the light guide layer after being reflected by the first illumination light reflective layer, wherein the display information and the illumination light are both emitted from the substrate of the display device;
• and
• an optical sensor, configured to sense the illumination light.
