After said television signal receiving system receives TV signal; Send TV signal to said processing television signals system; Said processing television signals system to processing television signals after, send said optical projection system to, through said optical projection system television image is rendered to extraneous the reception on the screen.
The present invention renders on the extraneous screen through the picture that projector system can be play TV.Screen can be a wall, perhaps other objects.The size of screen, the projection arrangement that does not receive to receive and to play TV limits.Can demonstrate the very big picture of size through the very little projection arrangement that receives and play TV of a volumes.Can be when satisfying people screen sizes required, carry and use and convenient.
The said projection arrangement that receives and play TV comprises that also one is used for the constant-current driven module to said projector system power supply, and said constant-current driven module adopts the high efficiency DC/DC conversion that combines with step-down of boosting to export to realize steady current.Guarantee the stable of projector system luminance brightness, avoided the flicker under the projection mode.
Said constant-current driven module can support to use lithium battery, also can support the power supply input under the external adapter.
Said television signal receiving system comprises a digital set-top box system.Be used for receiving digital television signal.
Said television signal receiving system comprises an anolog TV signals receiving system.Be used to receive anolog TV signals.
Said optical projection system comprises a projection light source, and said projection light source adopts LASER Light Source, comprises red laser light source, green laser light source, blue laser light source.Be used to produce red, green, blue three coloured light.
Said optical projection system also comprises a photomodulator, and said photomodulator adopts liquid crystal on silicon (LCOS).To reduce volume, cut down the consumption of energy.
Said optical projection system also comprises a beam shaping, and said beam shaping is a fly's-eye lens, and there is the phacoid of arranging with matrix form on the surface of said fly's-eye lens, and said beam shaping is between projection light source and object lens.So that the beam divergence that said light source penetrates, and convert the shape of the effective coverage of photomodulator to.
Between the projection lens assembly of said photomodulator and said optical projection system; There is the works that is used for fixing said photomodulator; The surface of contact of this works and said photomodulator forms opening surface, and the surface of contact of this works and said photomodulator scribbles the kermesinus rough coatings.The kermesinus rough coatings absorbs green glow, blue light, can weaken the blue halation that screen periphery forms.
Beneficial effect: owing to adopt technique scheme, the present invention can project television image by received television signal simultaneously, can be when satisfying people screen sizes required, and carry and use and convenient.The present invention makes common projector both have advantages such as volume is little, easy to carry, has the function that televiews again.
