影像顯示裝置Image display device

本發明是有關於一種影像顯示裝置，且特別是有關於一種可提升輸出影像的視野範圍的影像顯示裝置。The present invention relates to an image display device, and in particular to an image display device capable of improving the visual range of an output image.

在擴增實境（Augmented Reality, AR）的技術領域中，多採用固定影像深度之光學設計，例如波導式（waveguide）以及鳥盆式（birdbath）兩種架構。鳥盆式架構利用幾何光學方式實現大視野與優異的影像解析度，但其光學效率及整機輕薄度受光學架構限制。波導式架構雖能實現輕薄眼鏡型態的擴增實境產品，但其視野受限於選用基板的折射率有其視野的理論上限值。同時上述兩者架構因其固定影像焦面的特性，會使用者會因輻輳調節衝突（Vergence Accommodation Conflict，VAC）現象而產生不適感。In the field of augmented reality (AR) technology, fixed image depth optical designs are often used, such as waveguide and birdbath architectures. The birdbath architecture uses geometric optics to achieve a large field of view and excellent image resolution, but its optical efficiency and overall thinness are limited by the optical architecture. Although the waveguide architecture can achieve thin and light glasses-type augmented reality products, its field of view is limited by the refractive index of the selected substrate, which has a theoretical upper limit of its field of view. At the same time, due to the characteristics of the above two architectures with fixed image focal planes, users will feel uncomfortable due to the Vergence Accommodation Conflict (VAC) phenomenon.

視網膜投影的擴增實境裝置可克服上述的輻輳調節衝突現象所產生不適感。在視網膜投影設計中，大多使用全像光學元件（holographic optical element, HOE）。透過全像光學元件，可記錄光學元件的特性而得到具有大的視野的影像。但由於全像光學元件為繞射元件，對於入射光之波長相當敏感，故這一類方案大多僅使用在單色光源的應用上。Retina projection augmented reality devices can overcome the discomfort caused by the above-mentioned radiation adjustment conflict phenomenon. In retina projection design, holographic optical elements (HOE) are mostly used. Through holographic optical elements, the characteristics of optical elements can be recorded to obtain images with a large field of view. However, since holographic optical elements are diffraction elements, they are very sensitive to the wavelength of incident light, so this type of solution is mostly used only in applications with monochromatic light sources.

本發明提供一種影像顯示裝置，可提升輸出影像的視野。The present invention provides an image display device which can improve the visual field of output images.

本發明的影像顯示裝置包括多個微透鏡組以及成像裝置。微透鏡組以陣列形式排列。微透鏡組接收顯示影像，並分別產生多個影像光束，影像光束的行進方向不相互平行。成像裝置接收影像光束，聚焦影像光束以分別產生多個影像光束，並投射影像光束至目標區，以使各影像光束在目標區進行成像。The image display device of the present invention includes a plurality of micro lens groups and an imaging device. The micro lens groups are arranged in an array.

The imaging device receives the image beams, focuses the image beams to generate a plurality of image beams respectively, and projects the image beams to a target area so that each image beam forms an image in the target area.

基於上述，本發明的影像顯示裝置透過微透鏡組以產生多個行進方向不相互平行的影像光束，並藉以擴展輸出影像的視野範圍（Field of View, FOV），並可避免全像光學元件( holographic所產生的色散現象，提高影像的品質。Based on the above, the image display device of the present invention generates multiple image light beams with non-parallel travel directions through a micro lens set, thereby expanding the field of view (FOV) of the output image, avoiding the dispersion phenomenon caused by the holographic optical element, and improving the image quality.

The micro lens group 111-113 can be used to receive the display image DIM emitted by theimage projector 130, wherein the display image DIM can be distinguished into a plurality of output sub-images SDIM1-SDIM3 according to the display position. The micro lens group 111-113 is used to receive the output sub-images SDIM1-SDIM3 respectively, and collimate the output sub-images SDIM1-SDIM3 to generate a plurality of image beams IB1, IB2 and IB3 respectively. It is worth noting that in the present embodiment, the traveling directions of the image beams IB1, IB2 and IB3 are not parallel to each other. Moreover, the plurality of image sub-beams that can be contained in each image beam IB1, IB2 and IB3 are parallel to each other.

Theimage display device 400 includes animage projector 430, a plurality of micro-lens groups ML11~ML33, aspectroscope 422, and a focusingmirror 421. The micro-lens groups ML11~ML33 are disposed on the X-Z plane and arranged in an array. The micro-lens groups ML11~ML33 receive the display image DIM emitted along the Y-axis direction and generate a plurality of image light beams respectively. Please note that in this embodiment, the characteristics of the image light beams generated by the micro-lens groups ML11~ML33 are the same as the characteristics of the image light beams IB1~IB3 in the aforementioned embodiment, and will not be elaborated here.

其中，X、Y、Z為笛卡爾座標系（Cartesian coordinate system）的三個軸。Among them, X, Y, and Z are the three axes of the Cartesian coordinate system.

分光鏡422以及聚焦面鏡421構成成像裝置。在本實施例中，微透鏡組ML11~ML33以及分光鏡422沿顯示影像DIM的光軸進行配置，並且，分光鏡422則配置在聚焦面鏡421以及微透鏡組ML11~ML33間。在本實施例中，分光鏡422以及聚焦面鏡421產生成像點的方式與本案圖3的實施例中，成像裝置320產生成像點IP1~IP3的方法相同，在此不多贅述。其中，分光鏡422以及聚焦面鏡421在成像點區IPZ中，可透過聚焦多個影像光束來產生多個成像點。成像點區IPZ可以為目標區，並可對應使用者的眼球的位置進行設置。Thespectroscope 422 and the focusingmirror 421 constitute an imaging device.

In the present embodiment, the method in which thespectroscope 422 and the focusingmirror 421 generate imaging points is the same as the method in which theimaging device 320 generates imaging points IP1~IP3 in the embodiment of FIG. 3 of the present case, and will not be elaborated here. Among them, thespectroscope 422 and the focusingmirror 421 can generate multiple imaging points in the imaging point area IPZ by focusing multiple image light beams. The imaging point area IPZ can be a target area and can be set corresponding to the position of the user's eyeball.

透過二維排列的微透鏡組ML11~ML33，本實施例的影像顯示裝置400可在成像點區IPZ產生二維的多個輸出子影像，並透過拼接這些輸出子影像，可產生完成的輸出影像。Through the two-dimensionally arranged micro lens groups ML11 - ML33 , theimage display device 400 of this embodiment can generate a plurality of two-dimensional output sub-images in the imaging point zone IPZ, and can generate a complete output image by splicing these output sub-images.

在本實施例中，透過使多個輸出子影像可拼接成完整的輸出影像，可有效擴展輸出影像的影像視野。進一步的，在輸出影像的影像視野有效被擴充的前提下，在使用者旋轉眼球時，不會因為發生成像點未落於瞳孔中而造成影像缺失的現象。In this embodiment, by splicing multiple output sub-images into a complete output image, the image field of the output image can be effectively expanded. Furthermore, under the premise that the image field of the output image is effectively expanded, when the user rotates the eyeball, there will be no image loss due to the image point not falling in the pupil.

In addition, the image light beam is focused by the imaging device to generate multiple imaging points in the target area. The output image is generated by splicing multiple output sub-images corresponding to the multiple imaging points. In this way, the distribution area of the imaging points can be effectively expanded, and the field of view of the output image can be expanded accordingly. For example, when the human eye is placed at the central viewpoint, the viewpoint of viewing will be switched when the eyeball is rotated, and the image can be spliced into an image with a larger field of view on the retina of the human eye. Furthermore, in the embodiment of the present invention, the microlens set can be arranged without requiring too much space, thereby achieving the effect of expanding the visual field of the output image, and at the same time, the visible image can be maintained when the user's eyeballs move.
