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.
Claims20
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.

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.
