For example, one of advantage of convertible canvas 130 transparent (or translucent) is: when TV disconnected, described plate was transparent (or translucent), so can not block the sight line of back.In addition, compare with canvas 130 opaque situations, it is littler or so not huge and so not outstanding that TV seems.Certainly, if desired, described plate can be opaque, can be used as the canvas of surround lighting, rather than rear wall is as canvas.No matter whether convertible canvas 130 is transparent, convertible canvas 130 can have reflect ambient light 160 to give for example spectators' barrier and/or foam, and as having eliminated to the needs of rear wall and the canvas of disadvantages associated, for example to color, distance and the TV of suitable wall needs with respect to the orientation of rear wall, as above-mentioned U.S. Provisional Patent Application No.60/713, described in 184 (the file number US002308).

Certainly, convertible canvas 130 can have Any shape and/or size, comprises to spectators providing better environment photodistributed shape.For example, convertible canvas 130 can be limited to the framework that covers TV, thereby makes the TV framework convertible, and promptly under pellucidity, for example when TV during in off-state, television frame is visible; And under scattering state, as TV during in on-state; Framework is capped or is hidden in scattering and provides after the canvas 130 of surround lighting 160.The light source 150 that user interface 220 can be configured to the convertible canvas 130 of on/off and/or have nothing to do with the TV state.Therefore, even TV connects, the user also can be for example by keeping or providing suitable voltage to select to keep the transparency of convertible canvas 130 to convertible canvas 130; On the contrary, when TV disconnects, the user can select to connect light source 150, canvas 130 is transformed into scattering state (no-voltage is supplied with canvas 130), thereby provide background environment light, described background environment light can be controlled by the user, perhaps can be controlled by script or predetermined setting (being provided with etc. as romance).

According to the disclosure, other modification is conspicuous for the person of ordinary skill of the art.For example, convertible canvas with at least one light source and controller also can be as the framework around placard, artistic work and/or public/advertising message plate, framework with color that color with any hope or variation are provided perhaps is transformed into pellucidity and becomes invisible basically.
