The utility model content
The purpose of this utility model is to provide a kind of micro projector that is embedded into panel computer, to solve the problems of the technologies described above.
The technical matters that the utility model solved can realize by the following technical solutions:
The micro projector that is embedded into panel computer comprises a projector system, and described projector system comprises an optical projection system, also comprises a signal processing system, and described signal processing system connects described optical projection system;
Described projector system is used to be arranged in the panel computer, and described signal processing system is used for being connected with audio frequency and video disposal system in the described panel computer;
The audio-video signal of described audio frequency and video disposal system output sends described optical projection system to after described signal processing system is handled, by described optical projection system the picture on the screen of panel computer is rendered to extraneous the reception on the screen.
The utility model is by projector system the picture on the screen of panel computer to be rendered on the extraneous screen.Screen can be a wall, perhaps other objects.The size of screen, the micro projector that is not embedded into panel computer limits.Can demonstrate the very big picture of size by a very little micro projector that is embedded into panel computer of volume.Can be when satisfying people screen sizes required, carry and use and convenient.
The described micro projector that is embedded into panel computer comprises that also one is used for the constant-current driven module to described projector system power supply, and described constant-current driven module adopts the high efficiency DC/DC conversion module that combines with step-down that boosts to export to realize steady current.Guarantee the stable of projector system luminance brightness, avoided the flicker under the projection mode.
Described constant-current driven module can support to use lithium battery, also can support the power supply input under the external adapter.
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.
