Abstract

A lamp, for a vehicle, that includes at least one light source configured to generate light; a transparent display configured to allow at least a portion of the light to pass through the transparent display; and a processor configured to control the transparent display to display, on a projection surface using the light, information related to the vehicle or driving conditions for the vehicle is disclosed.

First claim

What is claimed is:

1. A lamp for a vehicle, comprising:
at least one light source configured to generate light;
a transparent display configured to allow at least a portion of the light to pass through the transparent display;
a position adjustment unit configured to adjust a position of the transparent display; and
a processor configured to control the transparent display to display, on a projection surface using the light, information related to the vehicle or driving conditions for the vehicle,
wherein the processor is further configured to:
receive user gaze information sensed by a camera,
change an area of the transparent display that defines a content or a pattern based on the user gaze information, and
control the position adjustment unit to change the position of the transparent display based on the user gaze information.

2. The lamp according to claim 1 , wherein the processor is configured to control the transparent display to display a pattern on at least one area of the transparent display.

3. The lamp according to claim 1 , wherein the processor is configured to display a predetermined content on the transparent display.

4. The lamp according to claim 1 , further comprising:
an aspheric lens configured to allow the light generated by the light source to be refracted and pass through the aspheric lens,
wherein the transparent display is disposed at a front end or at a rear end of the aspheric lens.

5. The lamp according to claim 1 , wherein the processor is configured to filter the information related to the vehicle or the driving conditions for the vehicle using an optical filter, wherein the optical filter is located at a windshield.

6. The lamp according to claim 1 , wherein the projection surface is a road surface, and
wherein the processor is configured to display driving lanes on the road surface.

7. The lamp according to claim 1 , wherein the processor is configured to display the information related to the vehicle or the driving conditions for the vehicle between the driving lanes.

8. The lamp according to claim 7 , wherein the processor is configured to display the information related to the vehicle or the driving conditions for the vehicle between the lanes based on curve information of a road on which the vehicle travels.

9. The lamp according to claim 1 , further comprising:
an interface unit configured to receive the information related to the vehicle or the information related to the driving condition for the vehicle,
wherein the information related to the driving condition for the vehicle includes forward objects information, rearward objects information, navigation information, road information, or driving environment information,
wherein the information related to the vehicle includes vehicle condition information, vehicle driving information, or in-vehicle situation information, and
wherein the light source comprises a headlamp.

10. The lamp according to claim 9 , wherein the interface unit receives distance information about a forward object ahead of the vehicle,
wherein the processor is configured to display the distance information on the projection surface.

11. The lamp according to claim 9 , wherein the road information comprises gradient information or curve information of a road on which the vehicle travels,
wherein the processor is configured to display the gradient information or the curve information on the projection surface.

12. The lamp according to claim 9 , wherein the forward objects information comprises traffic sign recognition (TSR) detection information or speed bump detection information,
wherein the processor is configured to display the TSR detection information or the speed bump detection information on the projection surface.

13. The lamp according to claim 12 , wherein the TSR detection information comprises traffic signboard detection information, traffic light detection information, and road surface detection information,
wherein the processor is configured to display, on the projection surface, information based on a design or text marked on a traffic signboard, a signal output from a traffic light, or a design or text marked on a road surface.

14. The lamp according to claim 12 , wherein the processor is configured to display, on the projection surface, a bump image based on the speed bump detection information.

15. The lamp according to claim 9 , wherein the forward objects information comprises other-vehicle detection information, two-wheeled vehicle detection information, pedestrian detection information, traffic accident information, construction information, or road congestion information,
wherein the processor is configured to display the other-vehicle detection information, the two-wheeled vehicle detection information, the pedestrian detection information, the traffic accident information, the construction information, or the road congestion information on the projection surface.

16. The lamp according to claim 15 , wherein the interface unit is configured to receive side vehicle detection information,
wherein the processor is configured to, based on the other-vehicle detection information, two-wheeled vehicle detection information or pedestrian detection information being received with the side vehicle detection information, display the other-vehicle detection information, two-wheeled vehicle detection information, or pedestrian detection information on a lane of a side vehicle.

17. The lamp according to claim 9 , wherein the navigation information comprises driving route information, preset destination information, remaining distance information, driving area information, driving road information, or speed camera information, wherein the processor is configured to display the driving route information, the preset destination information, the remaining distance information, the driving area information, the driving road information, or the speed camera information on the projection surface.

18. The lamp according to claim 17 , wherein the processor is configured to display a straight arrow, a left turn arrow, a right turn arrow, or a U-turn arrow on the projection surface as the driving route information.

19. The lamp according to claim 18 , wherein the interface unit is configured to receive side vehicle detection information,
wherein the processor is configured to, based on the driving route information being received with the side vehicle detection information, display the straight arrow, the left turn arrow, the right turn arrow, or the U-turn arrow on the lane of the side vehicle as the driving route information.

20. The lamp according to claim 9 , wherein the vehicle condition information comprises parking brake state information, high beam on/off information, washer liquid level information, engine oil level information, power source temperature information, remaining energy information, tire pressure information, brake oil condition information, or door opening information,
wherein the processor is configured to display the parking brake state information, the high beam on/off information, the washer liquid level information, the engine oil level information, the power source temperature information, the remaining energy information, the tire pressure information, the brake oil condition information, or the door opening information on the projection surface.

21. The lamp according to claim 9 , wherein the vehicle driving information comprises driving speed information, gear shift informat
