Embodiment 1

[0038] Such as Figure 1a As shown, the embodiment of the present invention provides an augmented reality AR display device, including: a first prism (2), a second prism 100 and a display screen (4);

[0039] The first prism (2) comprises a first lens unit, a second lens unit and a reflection unit; the first lens unit is close to the display screen (4), and the first lens unit and the display screen (4) are coaxially arranged, and the first lens unit The optical axis intersects with the optical axis of the second lens unit; wherein, the first prism (2) is a double spherical prism, and the first lens unit and the second lens unit are spherical lenses; the reflection unit is located between the first lens unit and the second lens Between the units, the reflective unit includes a slope;

[0040] The second prism 100 is a spherical prism, and the second prism 100 includes a light incident surface (S4) and an inclined surface, and the inclined surface of the second prism 100 is gl...

Embodiment 2

[0066] Such as figure 2 As shown, the embodiment of the present invention provides an augmented reality AR display device for reducing the volume of the first prism (2), including: the first prism (2), the second prism 100 and the display screen (4); It includes: a first lens (1), the first lens (1) is close to the second lens unit and coaxially arranged with the second lens unit.

[0067] For the specific content of the first prism (2), the second prism 100 and the display screen (4), refer to the above-mentioned embodiments, and will not repeat them here.

[0068] For the first lens (1), the first lens (1) is a positive lens, the side of the first lens (1) close to the second lens unit is a convex surface, and the convex surface is an aspherical surface; the first lens (1) is far away from the second lens unit One side is concave, and the concave surface is aspherical or spherical.

[0069] The purpose of increasing the first lens (1) is:

[0070] First, cooperate with t...

Embodiment 3

[0084] When the spherical surface of the first lens unit is a convex surface, the size of the display screen is limited and cannot be too large, so that the resolution of the display screen is required to be improved, and the chromatic aberration generated is also relatively large. Therefore, in order to reduce the size of the display screen volume, it is necessary to set a lens in the optical system for a higher degree of chromatic aberration correction, such as setting a lens for correcting chromatic aberration between the display screen and the first lens. Based on this, if image 3 As shown, the embodiment of the present invention provides an augmented reality AR display device, including: a first prism (2), a second prism 100, a display screen (4), a first lens (1); and a second lens ( 3);

[0085] For the specific content of the first prism (2), the second prism 100, the display screen (4) and the first lens (1), refer to the above-mentioned embodiments, and will not re...

Abstract

The invention discloses an AR display device and head-mounted AR display equipment, and the device comprises a first prism, a second prism, and a display screen. The first prism comprises a first lens unit, a second lens unit, and a reflection unit. The first lens unit is close to the display screen, and the first lens unit is arranged to be coaxial with the display screen. The light axis of the first lens unit and the light axis of the second lens unit are intersected with each other. The reflection unit comprises an inclined surface. The second prism is a spherical prism, and the second prism comprises a light-incoming surface and an inclined surface, wherein the inclined surface and the inclined surface of the reflection unit are glued together to form a glued surface. At least one of the inclined surface of the reflection unit and the inclined surface of the second prism is coated with a material with functions of transmission and reflection, thereby enabling the transmissivity and reflectivity of the glued surface to meet a set condition. The above device is small in size, is large in view angle, and can correct aberration.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular to an AR display device and a head-mounted AR display device. Background technique [0002] AR, (Augmented Reality), that is augmented reality, also known as mixed reality. It uses computer technology to apply virtual information to the real world. The real environment and virtual objects are superimposed on the same picture or space in real time. AR travels between virtual reality and reality. It not only shows the information of the real world, but also displays the virtual information at the same time. The two kinds of information complement and superimpose each other. In the visual augmented reality, users use the head-mounted display to multiplex the real world and computer graphics, and then they can see the real world surrounding it. [0003] Augmented reality display technology integrates computer graphics technology, computer simulation techno...
