1. A display-camera system comprising:
- a transparent display panel having a front surface to display images to a viewer and a back surface;
a transparent backlight panel having a front surface, a back surface and an edge, wherein the front surface of the transparent backlight panel is adjacent the back surface of the transparent display panel;
light sources to emit light into the edge of the transparent backlight panel;
a first polarizer, between the light sources and the edge of the transparent backlight panel, to polarize the light emitted from the light sources, wherein the transparent backlight panel is to direct the polarized light entering the edge of the transparent backlight panel towards the back surface of the transparent display panel; and
a camera, adjacent the back surface of the transparent backlight panel, to capture an image of a scene through the transparent display panel and the transparent backlight panel.

Abstract
According to an example, a display-camera system includes a transparent display panel and a transparent backlight panel. Light sources emit light into the edge of the transparent backlight panel. A first polarizer, between the light sources and the edge of the transparent backlight panel, polarizes the light emitted from the light sources and the transparent backlight panel directs the polarized light towards the transparent display panel. A camera, adjacent a back surface of the transparent backlight panel captures an image of a scene through the transparent display panel and the transparent backlight panel.

12. A display-camera system comprising:
-
a liquid crystal display (LCD) panel; light sources to illuminate the LCD panel; a transparent backlight panel adjacent the LCD panel; a first polarizer adjacent an edge of the backlight to polarize light emitted from the light sources, wherein the transparent backlight is to direct the polarized light entering the edge of the backlight towards a back surface of the LCD panel; a second polarizer adjacent a front surface of the LCD panel to polarize light emitted from the LCD panel; a camera, adjacent a back surface of the transparent backlight panel, to capture an image of a scene through the LCD panel and the transparent backlight panel, wherein to capture the image, the camera is to sense light from the scene, and the light from the scene sensed by the camera does not pass through the first polarizer. - View Dependent Claims (13, 14)

15. A method of displaying content and capturing images in a display-camera system, the method comprising:
-
emitting light from light sources towards an edge of a transparent backlight panel; polarizing the light prior to the light entering the edge of the transparent backlight panel; directing the polarized light through the backlight panel and towards a transparent display panel; displaying content on the transparent display panel; and capturing images of a scene in front of the display panel through the transparent display panel and through the transparent backlight panel.
