Embodiment Construction

[0043] The use of the same reference numbers in different drawings indicates the same or similar parts.

[0044] The inventors have recognized that the ambient lighting provided by backlighting 30 as shown in FIG. 2 is susceptible to being adversely affected by ambient lighting in the room or similar environment in which monitor 20 is located. This effect is schematically shown in FIG. 4 , where a backlight unit 100 is mounted on the back area of ​​the monitor 20 to project backlight 30 to an area 40 which is also illuminated by light from an ambient light source 110 (such as sunlight). and room lights) of the ambient lighting 120 influence. The ambient lighting 130 reflected from the area 40 is thus a combination of the reflected portion of the retrolight 30 and the reflected portion of the ambient lighting 120 . Furthermore, as mentioned above, the area 40 itself may correspond to a room wall painted in a color other than white, which color thereby spectrally affects the am...

Abstract

A display system (20, 100, 300, 320) is provided for presenting images to a viewer (50) together with complementary peripheral surround- lighting (130). The system (20, 100, 300, 320) includes a monitor (20) for presenting the images to the viewer (50), and lights (100) for generating the surround- lighting (130) appearing in operation to the viewer (50) as at least partially peripherally surrounding the monitor (20). Moreover, the system (20, 100, 300, 320) further includes a controller (320) for energizing the lights (100) in response to properties of portions of the images presented on the monitor (20), and a sensor (300, 310) for sensing the surround-lighting (130) and / or environmental illumination and generating corresponding sensor signals (330). The controller (320) is arranged in operation to receive the sensor signals (330) for controlling the lights (100) for at least partially compensating the surround-lighting (130) to influence from the environmental illumination.

Description

technical field [0001] The present invention relates to a display system for presenting an image to a viewer, wherein the system includes a display monitor and an associated surround-lighting unit operable to provide surround-lighting that complements the image presented on the monitor. Furthermore, the invention relates to a method for operating such a display system. Background technique [0002] Devices for presenting images to viewers are well known, including televisions and computer monitors. Current television implementations employ cathode ray tubes, liquid crystal displays utilizing pixel arrays, plasma displays, light emitting diode (LED) displays, just to name some current examples. For televisions, there is a growing need for relatively large screens to accommodate high-definition television (HDTV) programming content. However, the relatively large displays used in televisions are expensive to manufacture and tend to be bulky, especially when implemented using ...
