Please refer to the micro as shown in Figure 2. A top view of the deflecting array 300 and the projection module 220. In the first embodiment of the present invention, the number of the projection units 222 is equal to the number of the micro-deflection unit groups k1 to k16 (the six sides are arranged in sixteen Taking the four matrix as an example, and the direction in which the projection units 222 and the corresponding micro-deflection units 310 in each of the deflection units 330 are arranged is different by 180 degrees.

And the micro-deflection unit groups k1~k16 further deflect the image beam 201 in the same direction. Therefore, in the embodiment, the plurality of projection units 222 combined with the micro-deflection unit groups k1 - k16 can cause the display device 100A to have the image light beams 201 from the different projection units 222 in the direction surrounding the micro-deflection array 300, Further, a good stereoscopic image is formed.

More specifically, in an embodiment of the invention, the distance between the microlens array 210 and the micro-deflection array 300 is greater or smaller than the focal length of each microlens 212. distance. In detail, since the light-emitting end (for example, a projection lens) of the projection unit 222 (for example, a projector) is, for example, a circle having a diameter, the optical beam 201 emitted by the light-emitting end is perpendicular to its optical axis. The cross-section also has an illumination area, and the distance between the microlens array 210 and the micro-deflection array 300 is greater or smaller than the focal length of each microlens 212, so that the image beam 201 can reach the micro-deflection array 300.

Referring to FIG. 6B, in another embodiment of the present invention, the distance between the lens 400B and the projection module 220 may be adjusted to be larger than the focal length of the lens 400B depending on the difference of the light sources or the difference in the size of the microlens array 210. Further, in an embodiment of the present invention, the distance between the lens 400B and the projection module 220 is greater than the focal length of the lens 400B, and then the image beam 201 is concentrated after passing through the lens 400B, and the period of the deflection unit 330 needs to be compared. The period of the microlens array 210 is slightly smaller, and the micro-deflection unit in each micro-deflection unit group gradually changes according to the incident angle of the image beam 201 for the best effect, but is not limited thereto. In other embodiments, as the incident angle of the image beam 201 changes little, the micro-deflection unit 310 in each of the micro-deflection unit groups 300B can also adopt the same design to simplify the fabrication.
