Driver element, this control module communicates to connect with this projection module 11, first driver element and the second driver element respectively.
Specifically, this projection module 11 for being divided into multiple subimage by target image, and is projected by the plurality of subimage
Going out, the subimage of this projection module 11 projection is incident upon after sequentially passing through the reflection of this first reflecting mirror and the second reflecting mirror
On this screen 20；Wherein, when this control module controls the rotation of this first drive unit drives first reflecting mirror, this projection module exists
Projected position on this screen 20 moves along column direction, and this control module controls second drive unit drives the second reflecting mirror rotation
When turning, the projected position of this projection module 11 projection position on this screen 20 is moved along line direction；This control module control
Make this projection module 11 in preset time period, project multiple subimage successively, and anti-by this first reflecting mirror and second
Penetrate mirror and the plurality of subimage is reflexed to successively each projected position of this display screen 20, the corresponding projection of each described subimage
Position, the plurality of subimage is combined into target image.
Wherein, this first driver element and the second driver element all can use motor to drive.This control mould
Group can be single controller, it is also possible to being integrated in this projection module, certainly, it is not limited to this.This screen 20 can
To be conventional projection display screen, it is also possible to paste one layer of polarisation screen on this screen 20.
As shown in Figure 4, the plurality of the most rectangular shape of subimage 100, and rectangular array arrangement is to form this target image.
Specifically, in the present embodiment, this target image is divided into 3 row 4 and arranges 12 subimages 100 altogether, on this corresponding screen 20 also
It is divided into 3 row 4 and arranges 12 projected positions altogether.
During work, during the projection of each target image, in that is to say each first preset time period, control mould
Group controls this first drive unit drives first reflecting mirror and rotates the first predetermined angle every the second preset time period around a direction；
In one second preset time period, control module and control this second drive unit drives second reflecting mirror every the 3rd Preset Time
Section rotates one second predetermined angle around a direction.
Specifically, in the present embodiment, in the first preset time period:
In this first second preset time period, control module and control this projection module 11 at interval of the 3rd Preset Time
Section projects a subimage, that is to say, first projects first subimage to screen in first the 3rd preset time period
The position of the first row first row of 20；In second the 3rd preset time period, control this second drive unit drives second
Reflecting mirror rotates the second predetermined angle around first direction, and controls this projection module 11 and project second subimage to this screen
The position of the first row secondary series of curtain 20；In the 3rd the 3rd preset time period, controlling this second drive unit drives should
Second reflecting mirror rotates the second predetermined angle around first direction, and controls this projection module 11 and project the 3rd subimage extremely
The tertial position of the first row of this screen 20；In the 4th the 4th preset time period, control this second driver element and drive
This second reflecting mirror dynamic rotates the second predetermined angle around first direction, and controls this projection module and project the 4th subimage
The position arranged to this first row the 4th of screen 20.
In this second second preset time period, control module and control this first reflecting mirror of this first drive unit drives
Rotate the first predetermined angle around second direction, and control to project module 11 and project one at interval of the 3rd preset time period
Individual subimage 100, that is to say, first projects the 5th subimage 100 to screen 20 in first the 3rd preset time period
The position of the second row first row；In second the 3rd preset time period, control this second drive unit drives second and reflect
Mirror rotates the second predetermined angle around third direction, and control this projection module project the 6th subimage 100 to this second
The position of row secondary series；In the 3rd the 3rd preset time period, control this second reflecting mirror of this second drive unit drives
Rotate the second predetermined angle around third direction, and control this projection module and project the 7th subimage 100 to this second row
Tertial position；In the 4th the 4th preset time period, control this second reflecting mirror of this second drive unit drives around
Third direction and rotate the second predetermined angle, and control this projection module and project the 8th subimage 100 to this first row
The position of four row.Third direction is in opposite direction with first direction.
In the 3rd the second preset time period, control module and control this first reflecting mirror of this first drive unit drives
Rotate the first predetermined angle around second direction, and control to project module 11 and project one at interval of the 3rd preset time period
Individual subimage 100, that is to say, first projects the 9th subimage 100 to screen 20 in first the 3rd preset time period
The position of the second row first row；In second the 3rd preset time period, control this second drive unit drives second and reflect
Mirror rotates the second predetermined angle around first direction, and controls this projection module and project the tenth subimage 100 to the 3rd
The position of row secondary series；In the 3rd the 3rd preset time period, control this second reflecting mirror of this second drive unit drives
Rotate the second predetermined angle around first direction, and control this projection module 11 project the 11st subimage 100 to this
The three tertial positions of row；In the 4th the 4th preset time period, control this second reflection of this second drive unit drives
Mirror rotates the second predetermined angle around first direction, and controls this projection module 11 and project the 12nd subimage 100 to this
The position of the third line the 4th row.
Thus complete the display to a target image through above-mentioned steps, this first preset time period is less than 100ms,
Due to the persistence of vision of human eye, 12 subimages 100 shown successively in this 100ms appear to one by 12 at human eye
The target image that individual subimage 100 is constituted.
In another first preset time period that another is adjacent with this first preset time period, another is adjacent to that is to say display
Target image time, this control module control this first reflecting mirror of this first drive unit drives around fourth direction rotate, should
Fourth direction is in opposite direction with this second direction.It will of course be understood that ground, it is also possible to the direction phase of fourth direction and second direction
With, when direction is identical, when having shown a target image, this first driver element to drive this first reflecting mirror to reset, so
Rear continuation repeats above three step.
From the foregoing, it will be observed that the projection arrangement of present invention offer and optical projection system are by the first reflection module and the second reflection mould
The subimage that projection module projects is projected each projected position of screen in the first predetermined amount of time by group, due to people
The persistence of vision of eye, the image that human eye is seen is exactly the target image being made up of the plurality of subimage, forms a target figure
The subimage of picture has how many, and the resolution of former projection module just improves the multiple of correspondence, and therefore, the present invention has raising
The beneficial effect of the resolution of projection arrangement and optical projection system.
In sum, although the present invention is disclosed above with preferred embodiment, but above preferred embodiment and be not used to limit
The present invention processed, those of ordinary skill in the art, without departing from the spirit and scope of the present invention, all can make various change and profit
Decorations, therefore protection scope of the present invention defines in the range of standard with claim.
