Description
This application claims and submitted on 09 23rd, 2014 the right of priority that Patent Office of the People's Republic of China, application number are 201410490118.7, denomination of invention is the Chinese patent application of " a kind of full line scanning type laser projection display equipment " to, its full content combines in this application by reference.
Technical field
The application relates to technical field of laser display, is specifically related to a kind of laser white light module for full line scanning type laser projection display equipment and a kind of full line scanning type laser projection display system adopting described white light module.
Background technology
The quantity of information of the mankind 83% is obtained by vision, and only account for 27%, it can thus be appreciated that display device is for the significance of mankind's obtaining information by the quantity of information sum that the sense of hearing, sense of smell, the sense of taste and sense of touch obtain.Within 1897, Braun has invented CRT (Cathode-Ray-Tube, cathode-ray tube (CRT)), and the mankind enter the electronical display epoch since then.In more than the 100 year time afterwards, the mankind have invented various Display in succession, develop miscellaneous display device.Display device roughly can be divided into three kinds: a kind of is light emitting-type display, comprise CRT, LED (Light Emitting Diode, light emitting diode) display screen, OLED (Organic LightEmitting Diode, Organic Light Emitting Diode) display screen, PDP (Plasma Display Panel, plasma display panel) etc.; Another kind of is the display of backlight type, comprises LCD (Liquid Crystal Display, liquid crystal display); The third is projector.
CRT technology, in television receiver and tabletop display market, is replaced by LCD technology because its volume is too large; In large screen projection market, because its output light flux is not enough, replaced by LCD and DLP projector.At the initial stage that LCD TV and PDP TV are competed in domestic TV market and CRT TV, PDP once had half share with LCD with the advantage (color domain coverage ratio 38%) that its color is good; But along with the raising of LCD refreshing frequency and the progress of back light source technique, LCD TV has occupied most shares of TV market.Significantly improve although the LCD TV of LED backlight and the color representation power of display have had, its color domain coverage ratio still only has about 33%.The color domain coverage ratio of bulb projector is less than 30%.
The index passing judgment on display device performance quality mainly contains picture dimension, resolution, brightness, contrast, color representation power etc.Current flourish laser display technology, is expected to the performance index (as picture dimension, resolution, brightness and color representation power etc.) comprehensively surmounting display device in the past.
Laser display technology can be divided into several kinds.Wherein one is called LPD (Laser PhosphorDisplay, laser fluorescence powder show), its structure and CRT similar, but laser beam instead of electron beam; The blue laser beam that Several problems of evaluating laser beam quality of unstable sends, be irradiated to scribble fluorescent powder screen on excitated fluorescent powder luminous, control laser beam two-dimensional scan by vision signal and realize image display.The same with CRT, LPD is difficult to accomplish to resemble LCD thin, and picture dimension is also little, is that the mode of splicing realizes large screen display.The second is the Projection Display using LASER Excited Fluorescence powder light source, and do not re-use Gas lamp bubble, eliminate the maintenance work in the past frequently more changed the bulb, image quality also makes moderate progress simultaneously.The Projection Display of LASER Excited Fluorescence powder light source, not only color coverage rate does not have revolutionary breakthrough, and output light flux is by the restriction of the anti-laser intensity of fluorescent powder, is difficult to accomplish more than 10,000 lumens.The third laser display technology is the Projection Display using red-green-blue LASER Light Source, because mostly adopting DMD (Digital Micromirror Device) light valve, so there is people to be referred to as meaning laser DLP (Digital Light Processing), but also can adopt LCD light valve or LCOS (Liquid Crystal on Silicon, reflection-type liquid crystal light valve) etc.Compared with the Projection Display of LASER Excited Fluorescence powder light source, higher luminous flux and larger color domain coverage ratio can be obtained, but needing to eliminate laser speckle just can obtain desirable image quality.The resolution of laser DLP limits by light valve, and when large screen display, because its number of pixels is limited, although brightness can be very high, color is fine, and pixel is comparatively large, and image frame is visually fine and smooth not.4th kind is laser point by point scanning projection imaging technology, as shown in figure 11, red, green, blue three beams of laser, scans a point (a corresponding pixel) on screen simultaneously, controlled the power of three beams of laser by vision signal, carry out two-dimensional scan to realize coloured image display; Screen is projector's curtain (or rear projection screen) used, instead of the glass plate scribbling fluorescent powder as LPD or CRT.Laser point by point scanning projection imaging technology, resolution can be very high, but laser beam power is very high, stops scanning motionless, be easy to breaking out of fire, burn human eye or skin once light beam; Two-dimensional scan device is also comparatively complicated.
