Background technology
Along with the development of display technique, people have been developed and CRT, LCD and gas ions color monitor.This class display respectively has superiority, and in order further to improve display technology and to overcome the technological deficiency that existing display exists, the research of laser writer is the right turn up of a very short time.Though laser writer has high-fidelity, the advantage of high definition.But because technology more complicated such as high frequency galvanometer, and starting material and manufacturing cost have influenced the development of color laser desplay all than higher.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model provides a kind of scanister of laser writer, and it uses high speed scanner, not only can simplify the structure of laser writer, but also can reduce the manufacturing cost of laser writer.
The purpose of this utility model is achieved in that a kind of scanister of laser writer, comprises laser aid; Be provided with high speed scanner, high speed scanner is by support, constitute around property scan shaft, laser beam emitting head, deflection magnet and deflection coil group; Be provided with laser beam emitting head and deflection magnet around the property scan shaft, deflection magnet is corresponding with deflection coil; Laser beam emitting head connects laser aid.
On the basis of technique scheme, the utility model also has following further scheme:
Described laser aid is tristimulus signals modulator and red, blue, green tricolor laser device.
Described laser instrument is red, blue, green tricolor semiconductor laser diode.
Described laser beam emitting head is by magnifier or light channel directive screen.
Described screen is provided with the socket that can insert high speed scanner.
Described screen is a unit screen or multiple-unit screen, and laser beam emitting head is corresponding with screen.
Advantage of the present utility model is as follows:
Because high speed scanner uses around property scan shaft, deflection magnet and deflection coil.So scanning mechanism is much simpler than high frequency galvanometer of the prior art mechanism.The utility model not only can be realized high-velocity scanning, and helps reducing the manufacturing cost of laser writer.
After the utility model was taked further step, advantage was more outstanding:
Because laser is a kind of light source very efficiently, when described laser beam emitting head passes through magnifier or light channel directive screen, helps bringing into play the advantage of laser and make large screen display.
When described screen is provided with the high speed scanner socket, help reducing the manufacturing cost and the ease of assembly of screen.
When described screen is a unit screen or multiple-unit screen, when laser beam emitting head is corresponding with screen, can produce the display of high definition, and can realize that multi-screen is seamless spliced, produce the jumbotron of high definition.
