Description
This application claims and submitted Patent Office of the People's Republic of China, Application No. on 09 23rd, 2014
201410490118.7, the Chinese patent of invention entitled " a kind of full line scanning type laser projection display equipment "
The priority of application, entire contents is hereby incorporated by the application.
Technical field
The application relates to technical field of laser display, is specifically related to a kind of one-dimensional image device and a kind of employing
The full line scanning type laser projection display system of described one-dimensional image device.
Background technology
The quantity of information of the mankind 83% is obtained by vision, and is obtained by audition, olfactory sensation, the sense of taste and sense of touch
The quantity of information sum obtained only account for 27%, it can thus be appreciated that display device obtains the significance of information for the mankind.
Within 1897, Braun has invented CRT (Cathode-Ray-Tube, cathode ray tube), and the mankind are thence into electricity
The sub-display epoch.In year more than 100 afterwards, the mankind have invented various Display in succession, develop
Miscellaneous display device.Display device substantially can be divided into three kinds: one shows for light emitting-type, comprises
CRT, LED (Light Emitting Diode, light emitting diode) display screen, OLED (Organic Light
Emitting Diode, Organic Light Emitting Diode) display screen, (Plasma Display Panel, plasma shows PDP
Show plate) etc.；Another kind shows for backlight type, comprises LCD (Liquid Crystal Display, liquid crystal display
Device)；The third is scialyscope.
CRT technology is in radiotelevisor and tabletop display market, owing to its volume is too big by LCD technology
Replace；In large screen projection market, owing to its output light flux is not enough, replaced by LCD and DLP projector.
LCD-TV and PDP TV are at the initial stage in domestic TV market with the competition of CRT TV, and PDP is with its color
Good advantage (color domain coverage ratio 38%) once had half share with LCD；But along with LCD refreshing frequency
Improving and the progress of back light source technique, LCD-TV has already taken up most shares of TV market.Though
So the LCD-TV of LED backlight and the color representation power of display are obviously improved, but its colour gamut is covered
Lid rate still only has about 33%.The color domain coverage ratio of bulb scialyscope is less than 30%.
Pass judgment on the good and bad index of display device performance mainly have picture dimension, resolution, brightness, contrast,
Color representation power etc..The most flourish laser display technology, is expected to surmount conventional display device comprehensively
Performance indications (such as picture dimension, resolution, brightness and color representation power etc.).
Laser display technology can be divided into several kinds.One of which is referred to as LPD (Laser Phosphor
Display, laser fluorescence powder shows), its structure is similar with CRT, but laser beam instead of electron beam；Half
The blue laser beam that conductor blue laser sends, is irradiated to scribble excitated fluorescent powder on the screen of fluorescent material luminous,
Realize image by video signal control laser beam two-dimensional scan to show.As CRT, LPD is difficult to do
To thin as LCD, picture dimension is also little, is to realize large screen display in the way of splicing.The second
It is the Projection Display using LASER Excited Fluorescence powder light source, not in use by gas bulb, eliminates the most frequently
The maintenance work more changed the bulb, image quality also makes moderate progress simultaneously.The projection of LASER Excited Fluorescence powder light source
Display, not only color coverage rate does not has revolutionary breakthrough, and output light flux is by the anti-laser intensity of fluorescent material
Restriction, it is difficult to accomplish more than 10,000 lumens.The third laser display technology is to use red-green-blue to swash
The Projection Display of radiant, because mostly using DMD (Digital Micromirror Device) light valve, so
Someone is referred to as meaning laser DLP (Digital Light Processing) but it also may use LCD light valve or LCOS
(Liquid Crystal on Silicon, reflection-type liquid crystal light valve) etc..Projection with LASER Excited Fluorescence powder light source shows
Show and compare, it is possible to obtain higher luminous flux and bigger color domain coverage ratio, however it is necessary that elimination laser speckle
Just can obtain preferable image quality.The resolution of laser DLP is limited by light valve, when large screen display,
Owing to its number of pixels is limited, although brightness can be the highest, color is fine, but pixel is relatively big, and image is drawn
In facial vision fine and smooth not.4th kind is laser point by point scanning projection imaging technology, as shown in figure 11, red,
Three beams of laser green, blue, scans a point (a corresponding pixel) on screen, by video signal control simultaneously
The power of three beams of laser processed, carries out two-dimensional scan and shows to realize coloured image；Screen is used by scialyscope
Curtain (or rear projection screen) rather than scribble the glass plate of fluorescent material as LPD or CRT.Swash
Light point by point scanning projection imaging technology, resolution can be the highest, but laser beam power is the highest, once light beam
When stopping scanning motionless, it is easy to breaking out of fire, burn human eye or skin；Two-dimensional scan device is the most multiple
Miscellaneous.
