Abstract
Provided is a light shielding film for head-up display (HUD), the light shielding film including a plurality of light shielding materials configured to transmit a first directional light propagating from a view in front of a vehicle in a first direction and block at least a portion of a second directional light propagating from an external light source in a second direction that is opposite to a third direction in which light is output from a display panel for HUD included in the vehicle, at least one gradient of the plurality of light shielding materials corresponding to the first direction, and a transparent material that fills a space between the plurality of light shielding materials.
Claims23
A light shielding film for head-up display (HUD), the light shielding film comprising:
- a plurality of light shielding materials configured to transmit a first directional light propagating from a view in front of a vehicle in a first direction and block at least a portion of a second directional light propagating from an external light source in a second direction that is opposite to a third direction in which light is output from a display panel for HUD included in the vehicle, at least one gradient of the plurality of light shielding materials corresponding to the first direction;
- and
- a transparent material that fills a space between the plurality of light shielding materials,
- wherein the plurality of light shielding materials are configured to polarize light.
A head-up display (HUD) system for vehicle, the HUD system comprising:
- a display panel configured to output light including visual information;
- a magnification optical system configured to magnify the visual information to be displayed;
- and
- a light shielding film comprising a plurality of light shielding materials configured to transmit a first directional light propagating from a view in front of the vehicle in a first direction and block at least a portion of a second directional light propagating from an external light source in a second direction that is opposite from a third direction in which the light including the visual information is output from the display panel, at least one gradient of the plurality of light shielding materials corresponding to the first direction,
- wherein the plurality of light shielding materials are configured to polarize light.
