Abstract

A first image is generated at a first viewing angle during a first time by energizing a first LED zone to a first luminance. A second image is generated at a second viewing angle during a second time by energizing a second LED zone to a second luminance. The first luminance is directed at the first viewing angle by a first micro-lens disposed over the first LED zone and a parallax barrier. The second luminance is directed at a second viewing angle by a second micro-lens disposed over the second LED zone and the parallax barrier.

First claim

The invention claimed is:

1 . A system comprising:
a computer, including a processor and a memory storing instructions executable by the processor to: generate a first image at a first viewing angle during a first time by energizing a first LED zone to a first luminance; and generate a second image at a second viewing angle during a second time by energizing a second LED zone to a second luminance; wherein the first LED zone and the second LED zone are arranged in columns or a staggered rectangular array, and wherein the first luminance is directed at the first viewing angle by a first micro-lens disposed over the first LED zone and a parallax barrier, and the second luminance is directed at a second viewing angle by a second micro-lens disposed over the second LED zone and the parallax barrier which displays two different types of data to two different users from a single display device and wherein the first micro-lens is disposed above a plane defined by a display substrate that includes the first LED zone and the second LED zone and the second micro-lens is disposed below the plane.

2 . The system of claim 1 , wherein the first viewing angle and the second viewing angle are respective first and second angles relative to a display substrate formed by the first and second micro-lenses.

3 . The system of claim 1 , wherein multiple first LED zones combine to project the first image at the first viewing angle based on multiple first micro-lenses and the parallax barrier when the respective first LED zones are at the first luminance.

4 . The system of claim 3 , wherein the first image is a dynamic image in which the first luminance changes at frame rates greater than a threshold.

5 . The system of claim 1 , wherein multiple second LED zones combine to project the second image at the second viewing angle based on multiple second micro-lenses and the parallax barrier when the respective second LED zones are at the second luminance.

6 . The system of claim 5 , wherein the second image is a static image in which the second luminance changes at frame rates less than or equal to a threshold.

7 . The system of claim 1 , wherein at least one of the first micro-lens and the second micro-lens is offset relative to a plane defined by a display substrate formed by the first and second micro-lenses.

8 . The system of claim 1 , wherein at least one of the first micro-lens and the second micro-lens is tilted relative to a plane defined by a display substrate formed by the first and second micro-lenses.

9 . The system of claim 1 , wherein the first and second times are alternating time periods.

10 . The system of claim 1 , further comprising a vehicle dashboard supporting a display device including the first and second LED zones.

11 . The system of claim 1 , further comprising a first occupant area and a second occupant area spaced from the first occupant area, the first viewing angle being toward the first occupant area and the second viewing angle being toward the second occupant area.

12 . The system of claim 1 , further comprising a windshield, the first viewing angle being toward the windshield to be visible as a heads-up display and the second viewing angle being angled relative to the windshield to be visible as a direct display.

13 . A method comprising:
generating a first image at a first viewing angle during a first time by energizing a first LED zone to a first luminance; and generating a second image at a second viewing angle during a second time by energizing a second LED zone to a second luminance; wherein the first LED zone and the second LED zone are arranged in columns or a staggered rectangular array, and wherein the first luminance is directed at the first viewing angle by a first micro-lens disposed over the first LED zone and a parallax barrier, and the second luminance is directed at a second viewing angle by a second micro-lens disposed over the second LED zone and the parallax barrier which displays two different types of data to two different users from a single display device and wherein the first micro-lens is disposed above a plane defined by a display substrate that includes the first LED zone and the second LED zone and the second micro-lens is disposed below the plane.

14 . The method of claim 13 , wherein the first viewing angle and the second viewing angle are respective first and second angles relative to a display substrate formed by the first and second micro-lenses.

15 . The method of claim 13 , wherein multiple first LED zones combine to project the first image at the first viewing angle based on multiple first micro-lenses and the parallax barrier when the respective first LED zones are at the first luminance.

16 . The method of claim 13 , wherein multiple second LED zones combine to project the second image at the second viewing angle based on multiple second micro-lenses and the parallax barrier when the respective second LED zones are at the second luminance.

17 . An assembly comprising:
a display substrate; a first LED zone and a second LED zone each including a plurality of LEDs fixed to the display substrate; the first LED zone being energizable to a first luminance during a first time and the second LED zone being energizable to a second luminance during a second time; a parallax barrier spaced from the display substrate; and wherein the first LED zone and the second LED zone are arranged in columns or a staggered rectangular array, and a micro-lens array including a first micro-lens disposed over the first LED zone and a second micro-lens disposed over the second LED zone, wherein the first luminance is directed at a first viewing angle by the first micro-lens and the parallax barrier, and the second luminance is directed at a second viewing angle by the second micro-lens and the parallax barrier which displays two different types of data to two different users from a single display device and wherein the first micro-lens is disposed above a plane defined by a display substrate that includes the first LED zone and the second LED zone and the second micro-lens is disposed below the plane.

18 . The assembly of claim 17 , further comprising a vehicle dashboard supporting the display substrate, the first and second LED zones, the micro-lens array, and the parallax barrier.

19 . The assembly of claim 17 , further comprising a first occupant area and a second occupant area spaced from the first occupant area, the first viewing angle being toward the first occupant area and the second viewing angle being toward the second occupant area.

20 . The assembly of claim 17 , further comprising a windshield, the first viewing angle being toward the windshield to be visible as a heads-up display and the second viewing angle being angled relative to the windshield to be visible as a direct display.
