For achieving the above object, the invention provides following technical scheme:
The invention discloses the ultra-thin television of a kind of back projection and orthographic projection combination, comprise housing of TV set, the rear-projection display screen that housing of TV set dead ahead is installed and the micro projector that can rotate that housing of TV set inner tip is installed, and the reflecting optics staggered relatively with micro projector, function button is provided with below described housing of TV set side, described housing of TV set inside is provided with microprocessor and surface-mounted integrated circuit, surface-mounted integrated circuit is provided with the tuner of received television signal, the intermediate frequency amplifier circuit that vision signal and audio signal are separated, Video Decoder and audio decoder is connected with after described intermediate frequency amplifier circuit, described micro projector comprises light source, display chip and projection lens, light source adopts the synthesis light of laser and fluorescence as output light, is supplied to display chip light source under control of the microprocessor, and this light source realizes low speckle while can realizing large colour gamut when projecting, and improves picture texture and imaging effect when projecting.Described projection lens is embedded in the middle of semicircle rotating base, and projection lens regulates launching position by rotating.
As preferably, decoded vision signal under control of the microprocessor, is sent to the display chip of projecting apparatus by the video amplifier and digital signal processor by described Video Decoder; Video Decoder is provided with computer video signal interface.
As preferably, decoded audio signal under control of the microprocessor, is sent to loudspeaker by audio frequency amplifier by described audio decoder.
As preferably, described television set comprises projection diverter switch, producing and regaining switching for micro projector.
As preferably, the back cover of described housing of TV set is integral type structure, prevents projection light source from leaking, affects viewing effect.
As preferably, described micro projector is provided with automatic focusing device, when projection lens projects is to the ceiling of differing heights, and can automatic focusing.
As preferably, the distance of described micro projector and reflecting optics is greater than the projecting apparatus of conventional projection television and the distance of mirror surface, when reflection angle is constant, effectively reduces the thickness of TV fuselage, and fuselage thickness is 6-8cm.
Compared with prior art, the invention provides the ultra-thin television of a kind of back projection and orthographic projection combination, television set profile simplicity generosity, ultrathin design does not take up space, use the micro projector rotated, can switch back projection and orthographic projection at any time, can play dust-proof effect when camera lens is packed up simultaneously, projection lens rotates arbitrarily, projection scope is wide, by decoration restriction in family, more can project on the ceiling, user can lay flat on one's back viewing film.
