At present in 3LCD optical-mechanical system, due to projecting the illumination spot on tri- road Panel of RGB all than Panel itself
Greatly, this can sacrifice certain optical power efficiency, in order to balance efficiency and leakage side, it will usually in certain overfill
On the basis of (overfill is the ratio for beating hot spot general power at hot spot power and Panel outside Panel), pass through certain tune
Section means are transferred to the center of each RGB monochrome hot spot and are overlapped with the center of active area, accordingly even when after putting into complete machine
Deformation it is difficult to predict, but up and down adjusting surplus (actual facula beyond active area area size and active area it is big
Small ratio) can be relatively rationally and symmetrical, the leakage side of complete machine is bad and ray machine efficiency is all under control.
In the adjusting of the 3LCD optical-mechanical system of existing tri- color of RGB, blue light can change by adjusting blu-ray reflection mirror
The position of spot can change the position of feux rouges spot by adjusting red mirror, can be changed simultaneously by adjusting condenser red
The position of turquoise three hot spots.Wherein, due to optical path characteristic, when adjusting condenser, the mobile trend of bluish-green hot spot is consistent, and with
Feux rouges spot is opposite.
However, inventor is after being investigated existing some 3LCD optical-mechanical systems and adjusting method, it was found that at present
3LCD optical-mechanical system and its corresponding adjusting method there are some problems.
In a kind of existing 3LCD ray machine adjusting method, first get to condenser makes green spot leak side on one side, then
Adjusting blu-ray reflection mirror is overlapped blue light hot spot with green light hot spot, then adjusts red mirror and make feux rouges hot spot and bluish-green hot spot pair
Claim, the final condenser that adjusts is overlapped three hot spots.Wherein, judge to sentence by coincident when bluish-green hot spot is overlapped
It is disconnected, but edge imaging due to each monochromatic hot spot and uniformity are not so good as spot center, and the poor imaging in hot spot edge is (empty
Side) artificial judgment error can be brought, when two spot centers are not completely coincident, it will lead to and adjust surplus loss.Similarly, sentence
When disconnected feux rouges hot spot and bluish-green hot spot are symmetrical, it can only also be judged at a distance from active area edge by hot spot edge, empty side
Artificial judgment error can be brought.
And in another 3LCD ray machine adjusting method, first adjusting condenser makes green light spot center and active area center
It is overlapped (green light can only be adjusted by condenser), then adjust blu-ray reflection mirror and red mirror respectively to make blue light hot spot and feux rouges
The center of hot spot is overlapped with active area center.However, since the actual size of each RGB monochrome hot spot is to compare active area
Big, operator is unable to judge accurately whether tri- spot centers of RGB are overlapped with active area center when adjusting, if not weighing
It closes, then adjusts surplus asymmetry, the risk for putting into complete machine back leak side is also big.
In the course of the study, inventor has studied the structure of existing 3LCD ray machine internal optics, and how
It is improved in existing structure and adjusting method, to improve the not high problem of hot spot adjustment accuracy, and proposes this hair
