Description
Technical Field

Background
With the development of science and technology, wearable display devices have been widely used in various fields such as video, movies, medicine, simulation training, games, and so on. In recent years, Head Mounted Display (HMD) suitable for Virtual Reality (VR) or Augmented Reality (AR) has been developed. The conventional wearable display device for virtual reality generally includes a housing, a flat display panel and a convex lens. The convex lens images a picture of the flat display panel to generate an erect virtual image of the picture. After the user is provided with the wearable display device, various sensory simulations provided by a computer or an electronic device can be obtained by matching with special operation media, so that the user experience in the virtual world is achieved.
The size, weight, and imaging quality of the wearable display device are particularly important for a good user experience. In the conventional wearable display device, the size of the flat display panel and the distance between the convex lens and the display panel are too large, so that the size of the wearable display device is difficult to reduce. However, if the size of the flat display panel is reduced, the generated erect virtual image will be reduced, and the user experience will be reduced. If the distance between the convex lens and the flat display panel is reduced, the problem that the erected virtual image is reduced is also caused; in addition, when the convex lens and the flat display panel are too close to each other, the problem of aberration or uneven brightness is easily generated, which may cause a user to feel pressure and dizzy, and additional optical elements are required to be disposed to correct the aberration, which may increase the weight of the wearable display device. Therefore, how to provide a wearable display device that can satisfy the requirements of light weight, thinness and good image quality at the same time is one of the important issues in the related art.

The detailed features and advantages of the present invention are described in detail in the following embodiments, which are sufficient for anyone skilled in the art to understand the technical contents of the present invention and to implement the present invention, and the objectives and advantages related to the present invention can be easily understood by anyone skilled in the art according to the disclosure of the present specification, the scope of the claims and the accompanying drawings. The following examples further illustrate aspects of the present invention in detail, but are not intended to limit the scope of the invention in any way.
Please refer to fig. 1 to fig. 3. Fig. 1 is a perspective view of a display module according to a first embodiment of the invention. Fig. 2 is an exploded view of the display module of fig. 1. Fig. 3 is a schematic top view of the display module of fig. 1. In the present embodiment, the wearable display device 1 includes a housing 10, two lenses 20, and a display module 30. The wearable display device 1 is, for example, but not limited to, a head-mounted virtual reality display device.
The housing 10 includes a cover 110 and a supporting base 120. The supporting base 120 is disposed on the cover 110, and the cover 110 and the supporting base 120 together form an accommodating space 130. The carrier 120 has two openings 121 connected to the receiving space 130.
The lens 20 is, for example but not limited to, a convex lens, and is disposed in the opening 121 of the holder 120 of the housing 10. The lens 20 is, for example, but not limited to, a glass material or a plastic material. In the embodiment, the two lenses 20 are respectively disposed in the two openings 121 of the carrier 120, but the invention is not limited thereto. In some embodiments, the number of the openings of the lens and the carrying seat is one.
The display module 30 includes a display panel 310 and a prism 320. The display panel 310, such as but not limited to a liquid crystal display or an organic light emitting diode display, is disposed in the accommodating space 130 of the housing 10. The display panel 310 has two connected oblique display surfaces 311, and the display panel 310 has a connecting line 312 between the two oblique display surfaces 311. The two inclined display surfaces 311 extend from the connection line 312 in a direction approaching the lens 20. An included angle epsilon is formed between the two inclined display surfaces 311, and the included angle epsilon is larger than 0 degree and smaller than 180 degrees.
The prism 320 is disposed between the display panel 310 and the lens 20, and the prism 320 is, for example, but not limited to, a glass material or a plastic material. The prism 320 includes two refraction portions 321 connected, and the thickness of the refraction portion 321 gradually increases in a direction approaching the lens 20. The maximum thickness T of the refraction portion 321 is less than or equal to the minimum distance D between the display panel 310 and the lens 20, so that the prism 320 can be completely accommodated in the accommodating space 130.
In other words, an included angle α is formed between the light incident surface 321a and the light emitting surface 321b of each refraction portion 321, and the included angle α is smaller than 180 degrees, the light incident surface 321a and the light emitting surface 321b are respectively located at two opposite sides of the refraction portion 321, the two light incident surfaces 321a respectively face the two inclined display surfaces 311 of the display panel 310, the two light incident surfaces 321a respectively directly contact the two inclined display surfaces 311, the two light emitting surfaces 321b both face the lens 20, an included angle β is formed between the two light emitting surfaces 321b, and the included angle β is larger than 0 degree and smaller than 180 degrees, wherein the light incident surface 321a of one refraction portion 321 is parallel to one of the inclined display surfaces 311, and the light incident surface 321a of the other refraction portion 321 is parallel to the other inclined display surface 311.
In the present embodiment, the display panel 310 of the display module 30 has an inclined display surface 311, so that the display panel 310 is bent. Therefore, the volume of the accommodating space 130 occupied by the display panel 310 can be reduced, which is helpful for the housing 110 of the casing 10 to be light and thin, and further reduces the overall size of the wearable display device 1. In the present embodiment, when the display panel 310 is designed to be bent, the light emitted from the inclined display surface 311 cannot be parallel to the optical axis L of the lens 20, which results in aberration and lower peripheral brightness of the erected image of the picture generated by the lens 20. In order to solve the above problem, the present embodiment provides a prism 320 between the display panel 310 and the lens 20. Thereby, when the light emitted from the inclined display surface 311 passes through the prism 320, the traveling direction of the light can be corrected to be parallel to the optical axis L of the lens 20.
In this embodiment, in order to make the prism 320 correct the proceeding direction of the light, the appearance of the prism 320 needs to be designed, please refer to fig. 3 and fig. 4 together, wherein fig. 4 is a partially enlarged schematic view of the display module of the wearable display device of fig. 3, a horizontal reference plane 40 is defined to be perpendicular to the optical axis l of the lens 20, an included angle between the light incident surface 321a and the light emitting surface 321b of the refraction portion 321 of the prism 320 is α, an included angle between the light incident surface 321a of the prism 320 and the horizontal reference plane 40 is θ, a refractive index of the prism 320 is N1, and a refractive index of a medium between the light emitting surface 321b of the prism 320 and the lens 20 is N2, which satisfies the following conditions:
N1*sinα＝N2*sin(α+θ)。
when the conditions are satisfied, the prism 320 can correct the traveling direction of the light beam B to be parallel to the optical axis L of the lens 20, which is helpful for reducing aberration of the erected virtual image and improving the peripheral brightness thereof, a specific design method is used to illustrate that when the included angle θ between the light incident surface 321a and the horizontal reference surface 40 is 12.0 degrees, the refractive index of the prism 320 is 1.516, and the refractive index of the medium between the light emitting surface 321B of the prism 320 and the lens 20 is 1 (i.e., the refractive index of air), α + θ is obtained by substituting the above value for formula 2, and the included angle α is obtained by subtracting the included angle θ (12.0 degrees) from the value of α + θ, so that it can be known that the included angle α between the light incident surface 321a and the light emitting surface 321B needs to be designed to be 21.70 degrees, and in addition, the size of the prism 320 width determined in advance from the values of the included angle α and the included angle θ can be known, and thus the size of the housing 10 of the housing 30 can be known to provide a large housing 30.
When the included angle θ between the light incident surface 321a and the horizontal reference surface 40 is increased, the overall size of the wearable display device 1 can be effectively reduced; however, in some cases, the excessively bent display panel 310 may easily interfere with other parts of the wearable display device 1 during assembly, and the frame length of the display panel 310 may be smaller than the viewing angle of the user, which is not favorable for improving the user experience. In the present embodiment, the included angle θ between the light incident surface 321a and the horizontal reference surface 40 has a range of values, which is helpful for obtaining a good balance between the lightness and thinness of the wearable display device 1 and a good user experience. In the present embodiment, the included angle θ between the light incident surface 321a of the prism 320 and the horizontal reference surface 40 satisfies the following condition: 0[ degree ] < theta <14.0[ degree ], but the present invention is not limited thereto. In some embodiments, the following conditions may be further satisfied: 0[ degree ] < theta <12.0[ degree ]. In some embodiments, the following conditions may be further satisfied: 10.0[ degree ] < theta <12.0[ degree ].
In the first embodiment, the two refraction portions of the prism are integrally connected to each other, but the invention is not limited thereto. Fig. 5 is a schematic cross-sectional view of a wearable display device according to a second embodiment of the invention. Since the first embodiment is similar to the second embodiment, only different parts will be described below, and the description of the same parts will be omitted.
In this embodiment, the two refraction portions 321 of the prism 320 are two separable mirrors. When the two refraction portions 321 are disposed on the display panel 310, the side edges of the two refraction portions 321 contact the connection line 312 between the two inclined display surfaces 311.
In the first and second embodiments, the display panel is integrally formed, and the two inclined display surfaces are connected to the connecting lines, but the invention is not limited thereto. Fig. 6 is a schematic cross-sectional view of a wearable display device according to a third embodiment of the invention. Since the third embodiment is similar to the first and second embodiments, only the differences will be described below, and the descriptions of the differences will be omitted.
In the present embodiment, the wearable display device 1 "includes a display portion 310", and the display portion 310 "includes two display panels 311" and at least one signal transmission line 312 ". Each display panel 311 "has an inclined display surface 311 a". The opposite ends of the signal transmission line 312 ″ are connected to the two display panels 311 ″ respectively. Both the two inclined display surfaces 311a "extend from the signal transmission line 312" in a direction approaching the lens 20.
In summary, in the wearable display device disclosed in the present invention, the display panel has two oblique display surfaces connected to each other. The two refraction parts of the prism are respectively provided with a non-parallel light incident surface and a non-parallel light emergent surface. One of the light incident surfaces is parallel to one of the inclined display surfaces, and the other light incident surface is parallel to the other inclined display surface. Therefore, the size of the accommodating space occupied by the display panel can be reduced, the shell is light and thin, and the overall size of the wearable display device is reduced. In addition, the prism can correct the advancing direction of the light rays emitted by the display panel into the direction parallel to the optical axis of the lens, which is beneficial to reducing aberration and improving the peripheral brightness of the image. The structural configuration of the display panel and the prism is helpful for meeting the requirements of lightness, thinness and good imaging quality of the wearable display device at the same time.
In addition, compared with the method of directly shortening the distance between the lens and the flat display panel, the wearable display device disclosed by the invention still maintains enough distance between the lens and the central part of the display panel, which is beneficial to preventing the upright virtual image of the picture of the display panel from becoming smaller, and avoiding the imaging position deviation of the upright virtual image, thereby reducing the overall size of the wearable display device and maintaining good user experience.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
