Abstract: An oblong sized printed circuit board (1) comprises light emitting diode circuitry (2, 3). Parts of the printed circuit board (1) are flexible in at least one direction, to improve a manufacturing efficiency. Preferably, the printed circuit board (1) can make curves in length and width directions and does not require holes for screws. The light emitting diode circuitry (2, 3) may comprise light emitting diode circuits (2) with light emitting diodes and other circuitry (3) such as a driver for driving light emitting diode circuits (2) individually for providing ambient light for a display (5). A device (100) comprising the printed circuit board (1) may further comprise the display (5). Such a device (100) is for example a television receiver/display device/screen device. The printed circuit board (1) may be attached to structures (61, 62) moveable by hand/machine for directing the ambient light. The device (100) may be a roll (101) for rolling up the printed circuit board (1).

Abstract: A display device (10, 20, 30) is provided, the display device (10, 20, 30) comprising an LED array (33, 35, 12) working both as a backlight source for an LCD panel (31) and as an ambient light source providing ambient light with properties dependent on the image content presented by the LCD panel (31). A corresponding method and computer program product is also provided.

Abstract: A light emitting diode circuit (10) comprises a die with a light emitting diode for providing first ambient light (11) originating from a top side of the die and for providing second ambient light (12) originating from a bottom side of the die, to avoid complex and color dependent reflecting surfaces and to use the light more efficiently. The die may be placed on a substrate, planes of the die and the substrate being non-parallel planes, and the die may be at least partly surrounded by an at least partly transparent housing. A device (1) comprises the light emitting diode circuit (10) and a display/screen (2) supported by the first ambient light (11) having a first function like a support at a left/right/rear side of the device (1) and supported by the second ambient light (12) having a second function like a support at a left/right/front side of the device (1).

Abstract: A display system having 3D ambient light functionality is provided. The system comprises at least light source for providing ambient light having color and/or intensity dependent on the image content. The system comprises a control unit configured to control the color and intensity of light emitted from each light source to produce a 3D-viewing sensation, at least partly based on depth information.
