Described television signal receiving system comprises a digital set-top box system.Be used for receiving digital television signal.
Described television signal receiving system comprises an anolog TV signals receiving system.Be used to receive anolog TV signals.
Described optical projection system comprises a projection light source, and described 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.
Described optical projection system also comprises a photomodulator, and described photomodulator adopts liquid crystal on silicon (LCOS).To reduce volume, cut down the consumption of energy.
Described optical projection system also comprises a beam shaping, and described beam shaping is a fly's-eye lens, and there is the phacoid of arranging with matrix form on the surface of described fly's-eye lens, and described beam shaping is between projection light source and object lens.So that the beam divergence that described light source penetrates, and convert the shape of the effective coverage of photomodulator to.
Between the projection lens assembly of described photomodulator and described optical projection system, there is the works that is used for fixing described photomodulator, the surface of contact of this works and described photomodulator forms opening surface, and the surface of contact of this works and described 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 utility model can project television image by received television signal simultaneously, can be when satisfying people screen sizes required, and carry and use and convenient.The utility model makes common projector both have advantages such as volume is little, easy to carry, has the function that televiews again.
