## Abstract

A vehicle compartment includes a first display configured to irradiate light towards a driver reference position within the vehicle compartment and a first micro-louver structure disposed on the first display configured to reduce an angle range of light from the first display passing therethrough and to irradiate reduced angle light.

## Claims

### Claim 1

A vehicle compartment defining a lateral direction, the vehicle compartment comprising:
a first display configured to irradiate light towards a driver reference position within the vehicle compartment;
a first micro-louver structure disposed on the first display configured to reduce, in the lateral direction, an angle range of light from the first display passing therethrough and to irradiate reduced angle light;
a second display; and
a second micro-louver structure disposed on the second display configured to reduce, in the lateral direction, an angle range of light from the second display passing therethrough and to irradiate the light as reduced angle light,
wherein the reduced angle light irradiated by the first micro-louver structure is narrower than the reduced angle light irradiated by the second micro-louver structure.

### Claim 2

A vehicle compartment defining a lateral direction, the vehicle compartment comprising:
a first display configured to irradiate light towards a driver reference position within the vehicle compartment; and
a first micro-louver structure disposed on the first display configured to reduce, in the lateral direction, an angle range of light from the first display passing therethrough and to irradiate reduced angle light,
wherein the first micro-louver structure comprises:
a first portion disposed at a center of the first display configured to irradiate light passing therethrough as light having a first central axis in a first direction, and
a second portion laterally offset from the center of the first display that irradiates the light passing therethrough as light having a second central axis in a second direction that is different from the first direction,
wherein the first central axis and the second central axis are directed towards the driver reference position.

### Claim 3 (depends on 2)

The vehicle compartment of claim 2, wherein the first direction is perpendicular to the first display.

### Claim 4 (depends on 2)

The vehicle compartment of claim 2, wherein the second portion of the first micro- louver structure is disposed on an edge of the first display.

### Claim 5 (depends on 2)

The vehicle compartment of claim 2, wherein the first micro-louver structure comprises a third portion that irradiates the light passing therethrough as light having a third central axis in a third direction that is different from the first direction and the second direction.

### Claim 6 (depends on 5)

The vehicle compartment of claim 5, wherein the second portion of the first micro-louver structure is disposed on an edge of the first display, and the third portion of the first micro-louver structure is disposed between the first portion and the second portion on the first display.

### Claim 7 (depends on 1)

The vehicle compartment of claim 1, wherein the first display is an instrument panel display, and the second display is an infotainment system display.

### Claim 8 (depends on 2)

The vehicle compartment of claim 2, wherein the first display is an instrument panel display.

### Claim 9 (depends on 7)

The vehicle compartment of claim 7, further comprising:
a driver side window,
wherein the infotainment system display is configured to irradiate light towards both the driver reference position and a passenger reference position within the vehicle compartment, and
wherein the second micro-louver structure is structured such that none of the reduced angle light irradiated thereby is incident on the driver side window.

### Claim 10 (depends on 1)

The vehicle compartment of claim 1, further comprising a polarization structure formed on the first display.

### Claim 11 (depends on 10)

The vehicle compartment of claim 10, wherein the polarization structure transmits horizontally polarized light while restricting vertically polarized light from passing therethrough.

### Claim 12 (depends on 1)

The vehicle compartment of claim 1, further comprising:
a driver side window, and
an anti-reflective structure formed on the driver side window.

### Claim 13 (depends on 2)

The vehicle compartment of claim 2, further comprising:
a driver side window, and
an anti-reflective structure formed on the driver side window.

### Claim 14 (depends on 1)

The vehicle compartment of claim 1, further comprising:
a driver side window,
wherein the first micro-louver structure is structured such that none of the reduced angle light irradiated thereby is incident on the driver side window.

### Claim 15 (depends on 1)

The vehicle compartment of claim 1, wherein the first display is configured to irradiate horizontally polarized light while not irradiating vertically polarized light.

### Claim 16 (depends on 2)

The vehicle compartment of claim 2, further comprising:
a polarization structure disposed on the first display that transmits horizontally polarized light while restricting vertically polarized light from passing therethrough.

### Claim 17 (depends on 1)

A vehicle comprising:
a dashboard; and
the vehicle compartment according to claim 1,
wherein the first display and the second display are disposed on the dashboard.

### Claim 18 (depends on 2)

A vehicle comprising:
a dashboard; and
the vehicle compartment according to claim 2,
wherein the first display is disposed on the dashboard.

### Claim 19 (depends on 17)

The vehicle of claim 17, wherein the vehicle compartment comprises a driver side window, and the first micro-louver structure is structured such that none of the reduced angle light irradiated thereby is incident on the driver side window.

### Claim 20 (depends on 18)

The vehicle of claim 18, wherein the vehicle compartment comprises a driver side window, and the first micro-louver structure is structured such that none of the reduced angle light irradiated thereby is incident on the driver side window.
