BACKLIGHTING ARRAY SUPPORTING ADAPTABLE PARALLAX BARRIER
First Claim
1. A display system having a screen surface, the display system comprising:
- a backlight panel comprising an array of light sources, each of the light sources being individually controllable to select an amount of light emitted thereby;
a display panel comprising an array of pixels, each pixel being controllable to select an amount of light originating from the backlight panel that will be passed thereby; and
an adaptable parallax barrier that operates in conjunction with the backlight panel and the display panel to deliver at least a first three-dimensional visual presentation via the screen surface.

Abstract
Display systems are described that include an adaptable parallax barrier that filters light passed by a display panel in a manner that allows for the simultaneous viewing of two-dimensional images, three-dimensional images and multi-view three-dimensional content in different display regions. The display system also includes a backlight panel comprising an array of light sources that may be individually controlled to vary the backlighting luminosity provided to the display panel on a region-by-region basis. Since each of the display regions may be perceived as having a different number of pixels per unit area depending upon the type of content being presented, the backlight array enables the brightness of each region to be controlled such that a viewer perceives roughly uniform brightness across all regions. Alternative regional brightness control schemes are also described.

7. A method used to support delivery of both a first visual presentation via a first portion of a screen surface and a second visual presentation via a second portion of the screen surface, the method comprising:
-
delivering barrier control signals to cause placement of both first barrier elements into a first configuration and second barrier elements into a second configuration, the first barrier elements corresponding to the first portion of the screen surface, the first configuration being tailored to support the first visual presentation, the second barrier elements corresponding to the second portion of the screen surface, the second configuration being tailored to support the second visual presentation; delivering illumination control signals to cause simultaneous production of both a first illumination output and a second illumination output, the first illumination output being tailored to support the first visual presentation, the second illumination output being tailored to support the second visual presentation; and delivering signal representations corresponding to both the first visual presentation and the second visual presentation, the signal representations to be used via a plurality of display pixel elements to assist in generating both the first visual presentation and the second visual presentation. - View Dependent Claims (8, 9, 10, 11)

12. A display controller supporting simultaneous presentation of first video content and second video content on a display, the display having a screen that can be configured to have a first region and a second region, the first region corresponding to a first visual representation of the first video content, the second region corresponding to a second visual representation of the second video content, the first video content being stereoscopic three-dimensional content, the display control system comprising:
-
processing circuitry; a media interface through which both the first video content and the second video content are received by the processing circuitry; an interface element coupled to the processing circuitry; the processing circuitry sending via the interface element control signals to cause the configuration of the display in support of the presentation of both the first visual representation of the first video content in the first region and the second visual representation of the second video content in the second region, and the control signals being sent to establish a first backlight illumination associated with the first region and a second backlight illumination associated with the second region, the first backlight illumination having a brightness characteristic that differs from that of the second backlight illumination. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method used to support a visual presentation of three-dimensional content to a viewer via a screen, the viewer having a left eye and a right eye, the method comprising:
-
selecting a first manipulation configuration; selecting, based on the first manipulation configuration, a first brightness characteristic for both first light and second light, the first light intended for the left eye of the viewer while the second light intended for the right eye of the viewer; producing both the first light and the second light based on the first brightness characteristic; manipulating, based on the first manipulation configuration, the left eye light to try to prevent receipt of the left eye light by the right eye of the viewer; and manipulating, based on the first manipulation configuration, the right eye light to try to prevent receipt of the right eye light by the left eye of the viewer. - View Dependent Claims (19, 20, 21, 22, 23)
