Projector device
First Claim
1. A projector device, comprising:
- a projector unit, forming a light beam projecting image, wherein a horizontal projection width of the light beam projecting image is smaller than a vertical projection width of the light beam projecting image;
an optical light-splitting module, projecting one or a plurality of projection sub-images according to the light beam projecting image; and
a first image forming element, wherein the projection sub-images are respectively projected to the first image forming element to form one or a plurality of projection images,wherein the light beam projecting image comprises a plurality of split images, and the optical light-splitting module comprises;
a first optical lens set comprising a first reflective mirror and a second reflective mirror;
a second optical lens set; and
a third optical lens set comprising a third reflective mirror and a fourth reflective mirror,wherein the third reflective mirror of the third optical lens set overlaps with the first reflective mirror of the first optical lens set in a first direction, the third reflective mirror of the third optical lens set forms with the first reflective mirror of the first optical lens set in a second direction an angle from plus or minus 15 degrees to plus or minus 75 degrees, the third reflective mirror and the first reflective mirror present cross-shaped mutually in a plane formed by the second direction and a third direction, and the first direction, the second direction and the third direction are different from each other,wherein the third reflective mirror and the fourth reflective mirror of the third optical lens set are configured to project a first part of the light beam projecting image to the first image forming element to form a first projection sub-image,the second optical lens set is configured to project a second part of the light beam projecting image through the first image forming element to form second projection sub-image, andthe first reflective mirror and the second reflective mirror of the third optical lens set are configured to project a third part of the light beam projecting image to the first image forming element to form a third projection sub-image.

Abstract
A projector device is provided. The projector device includes a projector unit, an optical beam splitting module and a first image forming element. The projector unit forms a beam projecting image. The horizontal projection width of the beam projecting image is smaller than the vertical projection width of the beam projecting image. The optical beam splitting module projects one or multiple projection sub-images according to the beam projecting image. The projection sub-images are projected to the first image forming element to form one or multiple projection images. Thus, the projector device obtains multiple projection images from a single image source, and the placement of the image forming elements in the projector unit may be adjusted to obtain the projection images with the best image ratios and the best resolutions. The projector device may be suitable for a head up display.
