Problems solved by technology

The build process is very complex and requires many steps
Plus, it leads to higher parts prices
[0008] As mentioned above, although the problems of existing augmented reality display devices are obvious, optical technology has not overcome these problems so far.
Namely, so far, no compact optical modules have been developed for augmented reality, which is necessary for a compact wearer to wear in front of the eyes while achieving a wide field of view to technically maximize immersion.

Embodiment Construction

[0046] The present invention can be applied to various changes and can have various embodiments, and specific embodiments will be shown in the drawings and described in detail. However, this is not intended to limit the present invention to the specific embodiments, and should be construed to include all modifications, equivalents, and substitutions included in the spirit and scope of the present invention. In describing each figure, like reference numerals are used for like parts.

[0047] Terms such as first, second, A, and B may be used to describe various components, but the components should not be limited by these terms. These terms are used only for the purpose of distinguishing one component from other components. For example, a first component could be termed a second component, and similarly, a second component could be termed a first component, without departing from the scope of the present invention. The term and / or includes multiple related descriptive items or...

Abstract

Disclosed is an augmented reality display device. According to one aspect of the present embodiment, provided is an augmented reality display device comprising: a microdisplay; a relay lens array disposed on the rear end of the microdisplay and composed of a combination of at least two spherical or aspherical lenses; a combiner which is disposed on the rear end of the relay lens array, laterally projects image light, emitted from the relay lens array, toward a substrate described below, and generates an ultra-short focus image together with the relay lens array; the substrate which is transparent or translucent and onto which the image light delivered from the combiner is projected to form an image; and a coating or a film attached on a surface of one among a component of the relay lens array, the combiner, and the substrate to reflect, transmit, or refract the image light delivered from the microdisplay.

Description

technical field [0001] The present invention relates to an augmented reality display device, and more particularly, to an augmented reality display device, which can obtain a wider viewing angle and reflect a larger screen by adopting a method of projecting images directly in front of the eyes, while in No waveguide etc. are used when displaying images. Background technique [0002] What is described in this section merely provides background information of this embodiment and may not constitute prior art. [0003] Augmented reality technology is a technology that simultaneously displays real world and virtual images, and is a technology that superimposes and displays virtual objects on the real world. When the virtual image is superimposed on real-world objects in real-time with a high degree of realism, it can be difficult for the wearer to distinguish the real-world image from the virtually realized image. This technology is also known as mixed reality (MR). Augmented ...
