## Abstract

A display system for displaying digital content includes one or more LED-based lighting channels adapted to generate a first light output in a first operational mode at a first circadian stimulating energy (CSE), and a second light output in a second operational mode, the second light output associated with a second CSE, and a long red near infrared energy (LRNE) output in a third operating mode.

## Claims

### Claim 1

A display system for displaying digital content comprising:
a display screen;
an array of pixels, said pixels comprising one or more lighting channels configured to generate a first light output in a first operational mode at a first circadian stimulating energy (CSE), and a second light output in a second operational mode, the second light output associated with a second CSE, wherein said first CSE is greater than said second CSE; and,
a long red near infrared energy (LRNE) channel for emitting LRNE during at least one of said first or second operation modes, wherein said LRNE has a peak wavelength of at least one of 660 nm or greater than 700 nm.

### Claim 2 (depends on 1)

The display system of claim 1, wherein the LRNE is in the visible spectrum.

### Claim 3 (depends on 1)

The display system of claim 1, wherein the LRNE is in the non-visible spectrum.

### Claim 4 (depends on 1)

The display system of claim 1, wherein the LRNE is in both the visible and the non-visible spectrum.

### Claim 5 (depends on 1)

The display system of claim 1, wherein said array of pixels comprise as micro LED pixels or OLED pixels.

### Claim 6 (depends on 1)

The display system of claim 1, wherein said LRNE channel is discrete from said display screen.

### Claim 7 (depends on 1)

The display system of claim 1, wherein said LRNE channel emits light adjacent said display screen.

### Claim 8 (depends on 1)

The display system of claim 1, further comprising a panel adjacent said display screen, and wherein said LRNE channel emits light from said panel.

### Claim 9 (depends on 8)

The display system of claim 8, said panel is along an edge of said display screen.

### Claim 10 (depends on 1)

The display system of claim 1, further comprising a backlight for said display screen, said backlight comprising said one or more lighting channels.

### Claim 11 (depends on 10)

The display system of claim 10, wherein the LED-based lighting channels provide one or more white light sources for said backlight.

### Claim 12 (depends on 11)

The display system of claim 11, wherein the one or more white light sources are provided as white lighting channels comprising an LED and an associated luminophoric medium that produce a combined white light at a white color point within ±7 DUV of the Planckian locus on the 1931 CIE Chromaticity Diagram.

### Claim 13 (depends on 1)

The display system of claim 1, further comprising a controller configured to be in communication with said LRNE channel to selectively apply power thereto.

### Claim 14 (depends on 13)

The display system of claim 13, further comprising at least one sensor for supplying data to the controller and wherein the controller is configured to process the data and adjust the switching of the LRNE channel based, at least in part, on the data supplied by the sensor.

### Claim 15 (depends on 13)

The display system of claim 13, wherein the controller is in communication with one of a smartphone or a computer.
