Abstract

A display device for installation in a vehicle can include a first display configured to output first light forming first visual information; and a light synthesizing unit configured to pass the first light through the light synthesizing unit, and reflect second light and third light generated by different light sources, in which the light synthesizing unit includes a first light synthesizing portion disposed with a first surface of the first light synthesizing portion facing a first direction, and the first light synthesizing portion is configured to pass the first light through the first light synthesizing portion and reflect the second light; and a second light synthesizing portion disposed with a second surface of the second light synthesizing portion facing a second direction different from the first direction, and the second light synthesizing portion is configured to pass the first light through the second light synthesizing portion and reflect the third light.

Claims

1. A display device provided in a vehicle and configured to perform communication with at least one processor provided in the vehicle, the display device comprising:

a first display configured to output first light forming first visual information; and

a light synthesizing unit configured to pass the first light through the light synthesizing unit, and reflect second light and third light generated by different light sources,

wherein the light synthesizing unit comprises;

a first light synthesizing portion disposed with a first surface of the first light synthesizing portion facing a first direction, and the first light synthesizing portion is configured to pass the first light through the first light synthesizing portion and reflect the second light; and

a second light synthesizing portion disposed with a second surface of the second light synthesizing portion facing a second direction different from the first direction, and the second light synthesizing portion is configured to pass the first light through the second light synthesizing portion and reflect the third light.

2. The device of claim 1, further comprising a docketing area configured to receive a mobile device for generating the different light sources.

3. The device of claim 1, wherein the first light synthesizing portion is arranged with the first direction forming an acute angle between the first direction and the first display, and

wherein the second light synthesizing portion is arranged with the second direction forming an acute angle between the second direction and the second display.

4. The device of claim 3, wherein the first direction and the second direction form an angle less than or equal to 90 degrees.

5. The device of claim 1, further comprising a light absorbing unit disposed between the first light synthesizing portion and the second light synthesizing portion and the light absorbing unit is configured to absorb at least one of the second light and the third light.

6. The device of claim 5, wherein the light absorbing unit is configured to block the second light from proceeding to the second light synthesizing portion and block the third light from proceeding to the first light synthesizing portion.

7. The device of claim 5, wherein the light absorbing unit is arranged orthogonal to the first display, and one end of the light absorbing unit is connected to the first display.

8. The device of claim 1, further comprising a second display spaced apart from the first display with a predetermined angle between the first display and the second display,

wherein the second display includes a first portion configured to output the second light and a second portion configured to output the third light.

9. The device of claim 8, further comprising a reflection unit configured to reflect the third light output from the second portion of the second display and direct the third light to the second light synthesizing portion.

10. The device of claim 9, wherein the reflection unit is configured to tilt and vary a path of the third light based on the tilt of the reflection unit.

11. The device of claim 10, wherein a second angle between the reflection unit and the first display varies based on a speed of the vehicle.

12. The device of claim 9, wherein the second light synthesizing portion is configured to tilt and the second direction in which the second surface of second light synthesizing portion faces is adjusted based on the tilt of the second light synthesizing potion.

13. The device of claim 12, wherein second light synthesizing portion is configured to vary at least one of an output position and an output direction of information output from the second portion according to the second direction in which the second surface of the second light synthesizing portion faces.

14. The device of claim 9, wherein the second display is configured to:

display a main execution screen, and

in response to an occurrence of an event generation, divide the main execution screen into a first sub execution screen and a second sub execution screen,

wherein the first sub execution screen is output on the first portion of the second display in a first manner, and the second sub execution screen is output on the second portion in an inverted manner relative to the first manner.

15. The device of claim 14, further comprising a communication unit configured to receive the main execution screen from the at least one processor provided in the vehicle.

16. The device of claim 1, further comprising:

a second display configured to output the second light toward the first surface of the first light synthesizing portion; and

a third display configured to output the third light toward the second surface of the second light synthesizing portion.

17. The device of claim 16, wherein the second display is spaced apart from and faces toward the third display.

18. The device of claim 1, wherein the first light synthesizing portion is configured to pass the first light through the first light synthesizing portion and reflect the second light in a same direction as the first light output by the first display, and

wherein the second light synthesizing portion is configured to pass the first light through the second light synthesizing portion and reflect the third light in the same direction as the first light output by the first display.

19. The device of claim 1, wherein at least one of the first and second light synthesizing portions is configured to vary a transmittance property according to a preset condition.

20. A display device for installation in a vehicle, the display device comprising:

a first display configured to output first light forming first visual information;

a light synthesizing unit configured to pass the first light through the light synthesizing unit, and reflect second light and third light generated by different light sources; and

a docking area configured to receive a mobile device for generating the different light sources,

wherein the light synthesizing unit comprises;

a first light synthesizing portion having a first surface facing a first direction, and the first light synthesizing portion being configured to pass the first light through the first light synthesizing portion and reflect the second light; and

a second light synthesizing portion having a second surface facing a second direction different from the first direction, and the second light synthesizing portion being configured to pass the first light through the second light synthesizing portion and reflect the third light,

wherein the first light synthesizing portion is configured to tilt, and the first direction in which the first surface of first light synthesizing portion faces is adjusted to vary a direction of the second light reflected by the first light synthesizing portion based on the tilt of the second light synthesizing potion,

wherein the second light synthesizing portion is configured to tilt, and the third direction in which the second surface of second light synthesizing portion faces is adjusted to vary a direction of the third light reflected by the second light synthesizing portion based on the tilt of the second light synthesizing potion, and wherein at least a portion of the first light overlaps with the second light or the third light to provide a three dimensional (3D) image.
