Description
Technical field
Laser screen speckle eliminating device technical field is the utility model is related to, is shaken more particularly to a kind of screen
Dynamic device.
Background technology
Laser projector is generally used during cinema screening at present, its advantage is that light stability, brightness height, and use
Long lifespan, but when image is by laser projection to screen, reflex can be produced, some light can be through reflecting into
Enter in spectators' eye, due to optical maser wavelength high unity, laser has stronger energy in itself in addition, makes one visually to produce very
Strong speckle phenomena, the speckle phenomena of screen seriously affects presentation picture quality in laser projection system so that the viewing of spectators
Effect is greatly affected, the problem of being anxious to be resolved in the industry.Existing solution method, for example adjusts laser projection lens, and effect is poor,
And expend great amount of cost.
Screen is vibrated currently on the market mainly by the way of single motor drives whole screen carrier vibration, and this method will
It must be to be flexible coupling with main body shelf to ask and hang up the frame of screen, i.e. the frame of main body shelf and lacing screen separates, and passes through high pressure
Spring connects, and starts motor, drives the frame of lacing screen to vibrate, and screen vibration is further driven to, so as to reach elimination light
The purpose of spot.The screen shelf cost of this method is larger, and the vibration of the frame of main body shelf and lacing screen produces machinery and makes an uproar
Sound is larger, and screen surface vibration is uneven, and ecchymose removing effect is poor.
Chinese invention patent, publication number：CN105759553A, publication date：On 07 13rd, 2016, disclose a kind of screen
Speckle, which removes system and its speckle minimizing technology, the system, to be included：Multiple transducers for being used to vibrate screen, for according to screen
Parameter calculates the intelligent controller of the corresponding vibration data of multiple transducers, and multiple is used to parsing the vibration data and right
The focus scanner of each transducer should be controlled, the intelligent controller connects multiple focus scanners, the multiple shake respectively
Source scanner connects one to one with multiple transducers.Include being used for fixed silver in practical application, screen speckle removes system
The screen supporting rack of curtain, the multiple transducers being arranged on screen supporting rack, the transducer include being arranged on screen supporting rack
On vibration source cabinet and oscillator, the oscillator be used for shake screen.Screen is set to produce vibrations by transducer, when screen shakes
When reaching certain frequency, dynamic diffusing reflection occurs for the laser being mapped in screen, reduces screen speckle generation, it might even be possible to completely
Dispel speckle.But the patent to support frame structure and can not call out the arrangement of device and elaborate, if device skewness can be called out
Screen local vibration can be caused excessive or too small, local speckle eradicating efficacy is poor, influences viewing quality, and in addition vibration source is directly set
Putting may cause supporting rack to resonate, so as to produce loud noise, while influence the use of supporting rack in supporting rack, vibration source vibration
Service life.
