Description

Display device and augmented reality equipment

Technical Field

The disclosure relates to the technical field of display, in particular to a display device and an augmented reality device.

Background

The augmented reality technology is an immersive display technology, provides a display picture of about 100 degrees for a wearer, and gives people a realistic, shocking and immersive visual feeling. The augmented reality display device enlarges an image displayed on a micro display screen (LCD, OLED, microLED, LCOS, etc.) through a lens/lens group to form a virtual image for viewing by a wearer.

Limited by the state of the art, the screen resolution of an augmented reality display device cannot match the field angle of the display picture, the pixel density (Pixels PER Degree, PPD) is insufficient, resulting in a grainy feel of the displayed picture and gaps between pixels/RGB sub-pixels. These gaps are also magnified, becoming black squares, which are seen by the wearer, making the wearer feel looking through a screen, and so this phenomenon is known as the screen effect,

in order to eliminate the screen window effect, a micro lens is allocated to each pixel/RGB sub-pixel, a single micro lens amplifies the corresponding pixel/RGB sub-pixel into a virtual image, and the amplified virtual image of each pixel/RGB sub-pixel forms a virtual image array with a small or even vanishing pixel gap, so that the screen window effect of the virtual image array is obviously improved after the lens is amplified. However, this method has high requirements for the arrangement of the microlens array, and once the uniformity of the arrangement of the microlens array does not reach the standard, or the microlens is misaligned with the pixels/RGB sub-pixels, undesirable phenomena such as streaks (grainy-imaging images) may occur in the display screen.

Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.

As described in the background art, although a microlens is provided for each pixel/RGB sub-pixel, the screen window effect can be improved to a certain extent, but the arrangement requirement of the microlens array is high, once the arrangement uniformity of the microlens array does not reach the standard, or the microlens is not aligned with the pixel/RGB sub-pixel, the adverse phenomena such as streaks (grainy-looking images) can occur in the display screen.

The reason for this is that the microlens array is a single lens, and in practice, the two microlenses will often be separated by a distance (of course less than the distance between the two pixels/RGB sub-pixels) due to process limitations. If the arrangement uniformity of the microlens array does not reach the standard, or if the microlenses are not aligned with the pixels/RGB sub-pixels, the interval between some adjacent microlenses may be excessively large, and the light emitted from the pixels/RGB sub-pixels cannot completely cover the gaps between the adjacent microlenses even though the light is diffused through the microlenses, so that the gaps between the adjacent microlenses are still black, and visually, streaks appear.

In view of this, fig. 1 is a schematic structural diagram of a micro display in a display device according to an embodiment of the disclosure, fig. 2 is a schematic structural diagram of a dimming film in a display device according to an embodiment of the disclosure, fig. 3 is a schematic structural diagram of the micro display in fig. 1 and the dimming film in fig. 2 after being overlapped, and fig. 4 is a cross-sectional view along A1-A2 in fig. 3. Referring to fig. 1 to 4, the display device includes: the micro display 10 and the dimming film 20 disposed on the light emitting side of the micro display 10. The micro display 10 includes a plurality of light emitting regions 11 arranged at intervals and non-light emitting regions 12 surrounding each light emitting region 11. A light emitting unit (not shown in the drawing) is provided in the light emitting region 11. The dimming film 20 includes a light-transmitting region 21 and a dimming region 22; the light-transmitting region 21 corresponds to the light-emitting region 11 so that light emitted from the light-emitting unit passes through the light-transmitting region 21; the dimming area 22 corresponds to the non-light-emitting area 12, and a microstructure 221 is disposed on the dimming area 22 to fill the non-light-emitting area 12 with light emitted from the light-emitting unit.

In the present disclosure, the Micro display may specifically be a liquid crystal Micro display (Liquid Crystal Display, LCD), an Organic Light-Emitting Diode (OLED), a Micro LED Micro display, a liquid crystal on silicon (Liquid Crystal on Silicon, LCOS) Micro display, and the like.

In the present application, the light emitting unit located in the light emitting region may be an active light emitting unit or a passive light emitting unit. The active light emitting unit refers to a structure capable of emitting light by itself. The passive light emitting unit is a structure which can not emit light by itself and can emit light only by means of the backlight module. For example, if the micro display is a liquid crystal micro display, the light emitting unit is a pixel or an RGB sub-pixel, and in this case, the light emitting unit is a passive light emitting unit. If the micro display screen is an organic light-emitting micro display screen, the light-emitting unit is a light-emitting unit comprising an anode, an organic light-emitting layer and a cathode, and at this time, the light-emitting unit is an active light-emitting unit. If the Micro display screen is a Micro LED Micro display screen, the light emitting unit is a Micro LED, and at the moment, the light emitting unit is also an active light emitting unit.

The microstructure is arranged in the dimming area, namely, the surface of the dimming film is provided with a plurality of convex structures and/or concave structures in the dimming area, so that the whole surface is in a concave-convex shape. In practice, there are a variety of shapes for the raised structures, which the present disclosure is not limited to. Alternatively, the shape of the raised structures includes, but is not limited to, hemispherical, conical or pyramidal. In practice, there are a variety of shapes for the recessed structures, which the present disclosure is not limited to.

In practice, there are various methods of making microstructures, which the present disclosure is not limited to. Illustratively, the microstructure is obtained by coating microparticles on the surface of the dimming area; or the microstructure is obtained by embossing the surface of the dimming area; or the microstructure is obtained by etching the surface of the dimming area; alternatively, the microstructure is obtained by providing a microlens array on the surface of the light modulation region.

In fig. 4, the dimming film 20 exemplarily includes a base film 23, and a microstructure 221 formed on the base film 23. The microstructures 221 protrude from the surface of the base film 23 near the microdisplay 10. The microstructure 221 is obtained by coating fine particles on the surface of the base film 23, or the microstructure 221 is obtained by providing a microlens array on the surface of the base film 23.

Fig. 5 is a schematic structural diagram of another display device according to an embodiment of the disclosure. In fig. 5, the dimming film 20 exemplarily includes a base film 23, and a microstructure 221 formed on the base film 23. The microstructures 221 do not protrude from the surface of the base film 23 adjacent to the microdisplay 10. Illustratively, the microstructures 221 are obtained by treating the base film 23. For example, the microstructure is obtained by embossing the surface of the base film 23; alternatively, the microstructure is obtained by etching the surface of the base film.

The fact that the dimming area 22 corresponds to the non-light-emitting area 12 means that the dimming area 22 can shade at least part of the non-light-emitting area 12 in the reverse direction of the light emitted from the light-transmitting area 22 when the display device is used by a user.

The light modulation region 22 is provided with a microstructure 221, and light emitted from the light emitting unit enters the microstructure 221, and is scattered, diffracted, or refracted on the microstructure 221, and then exits from the microstructure 221 to enter the human eye, so that the human eye can sense the light emitted from the region where the microstructure 221 is provided (i.e., the light modulation region). Because the dimming area 22 corresponds to the non-light-emitting area 12, the dimming area 22 has a shielding effect, and the non-light-emitting area is visually lightened, so that the purpose of improving or eliminating the screen window effect is achieved. In the technical scheme of the disclosure, the existing micro-lens array arranged for the pixels/RGB sub-pixels is replaced by the dimming film, so that the dimming film is not limited by the arrangement requirement of the micro-lens array, and the adverse phenomenon caused by the fact that the arrangement of the micro-lens array does not meet the arrangement requirement can be avoided.

The light-transmitting region 21 corresponds to the light-emitting region 11, and means that the light-transmitting region 21 can block at least part of the light-emitting region 11 in the reverse direction of the light emitted from the light-transmitting region 22 when the display device is used by a user.

In the above technical solution, the light-transmitting area 21 corresponds to the light-emitting area 11, and no microstructure is provided in the light-transmitting area 21, that is, after entering the light-transmitting area 21, the light emitted from the light-emitting unit can directly exit from the light-transmitting area 21 and enter the human eye. The whole light transmission process is not influenced by the microstructure, and the brightness and the definition of the screen are not influenced.

The technical scheme is not only suitable for the micro display screen with smaller size of the light-emitting units and larger size of the gap distance between the light-emitting units, but also suitable for the micro display screen with larger size of the light-emitting units and smaller size of the gap distance between the light-emitting units.

With continued reference to fig. 2-5, optionally, in the dimming film 20, a plurality of light-transmitting regions 21 are disposed at intervals, and the dimming region 22 surrounds each light-transmitting region 21; the light-transmitting areas 21 are in one-to-one correspondence with the light-emitting areas 11. The essence of this is that the dimming area 22 in the dimming film 20 is similar or identical to the non-light-emitting area 12 of the micro display 10 in shape, so that the dimming area 22 shields the non-light-emitting area 12 as much as possible, further improving or eliminating the effect of the screen effect.

The display device provided by the technical scheme can be applied to the augmented reality display equipment. The display device comprises a display device, a lens system and an optical film set, wherein the lens system and the optical film set are located on the light emitting side of the dimming film. The lens system is used to magnify the microdisplay. Alternatively, the lens system may include one or more of an aspherical lens, an aspherical-fresnel lens, a spherical lens, and a mirror. Illustratively, the lens system is a Pancake refractive optical lens system. The optical film group comprises a wave plate, a polarization beam splitting film, a polarizer and other optical films.

In practice, the optical devices including the micro-display screen and the lens system may be set as a telecentric optical system, or the optical devices including the lenses may be set as a non-telecentric optical system.

If the light beam for imaging emitted from the light emitting units in the micro display is regarded as a cone, for the telecentric optical system, the axis of the light beam for imaging emitted from each light emitting unit in the micro display is approximately perpendicular to the light emitting surface of the micro display. For example, referring to fig. 4, the axis m of the light beam emitted by each light emitting unit of the micro display screen for imaging is perpendicular to the light emitting surface n of the micro display screen 10. In other words, the axis m of the light beam emitted from the light emitting unit for imaging is approximately perpendicular to the light emitting surface n of the micro display 10, whether the light emitting unit is located at the center of the micro display, at the edge of the micro display, or at other positions.

In one embodiment, for a telecentric optical system, the vertical projection of the light emitting area of the micro display screen on the plane of the dimming film is at least partially coincident with the light transmitting area corresponding to the light emitting area; the non-light-emitting area of the micro display screen is at least partially overlapped with the light-adjusting area through the vertical projection of the plane of the light-adjusting film. This arrangement ensures that the dimming area is capable of shielding at least part of the non-light-emitting area and the light-transmitting area is capable of shielding at least part of the light-emitting area.

Further, referring to fig. 2 to 4, in the micro display 10, a plurality of light emitting areas 11 are arranged in an array; the distance between the geometric centers of two adjacent light-transmitting regions 21 in the row direction or the column direction of the array is a first distance, and the distance between the geometric centers of two adjacent light-emitting regions 11 is a second distance, the first distance being equal to the second distance. This arrangement may further ensure that the dimming region 22 is able to block as much of the non-light emitting region 12 as possible, thereby improving or eliminating the effect of the screen effect.

If the light beam for imaging emitted from the light emitting unit in the micro display screen is regarded as a cone, for a non-telecentric optical system, the included angle between the axis of the light beam for imaging emitted from at least part of the light emitting units in the micro display screen and the light emitting surface of the micro display screen is an acute angle.

Optionally, the microdisplay includes a central region and a non-central region surrounding the central region, each of the central region and the non-central region including a light-emitting region and a non-light-emitting region. In the micro display screen, a plurality of luminous areas are arranged in an array; the distance between the geometric centers of two adjacent light-transmitting areas is a first distance along the row direction or the column direction of the array, and the distance between the geometric centers of two adjacent light-emitting areas is a second distance; in the central area of the micro display screen, the first distance is equal to the second distance; in a non-central region of the microdisplay, the first distance is not equal to the second distance. The central area is a preset range centered on the geometric center of the microdisplay. The non-central region refers to a region of the micro display screen other than the central region.

In the non-central area, if the axes of the light beams emitted by the light emitting units in the light emitting areas are gathered towards the center (i.e. the geometric center) of the micro display screen, the corresponding dimming areas of the light emitting areas are offset towards the center (i.e. the geometric center) of the micro display screen. And otherwise, the dimming area corresponding to the luminous area is offset to the edge of the micro display screen.

Fig. 6 is a schematic structural diagram of another display device according to an embodiment of the disclosure. In fig. 6, in the micro display, an axis m of a light beam for imaging emitted from a light emitting unit located in a central area of the micro display is perpendicular to a light emitting surface n of the micro display. The included angle between the axis m of the light beam emitted by the light-emitting unit used for imaging and the light-emitting surface n of the micro display screen is an acute angle. The axis m of the light beam for imaging, which is emitted from any one of the light emitting units located in the non-central area of the micro display screen, is gathered toward the center (i.e., geometric center) of the micro display screen.

Fig. 7 is a schematic structural view of the light modulation film in fig. 6. Referring to fig. 6 and 7, in the micro display 10, a plurality of light emitting areas 11 are arranged in an array; the distance between the geometric centers of two adjacent light-transmitting areas 21 is a first distance, and the distance between the geometric centers of two adjacent light-emitting areas 11 is a second distance along the row direction or the column direction of the array; in the central region of the micro display 10, the first distance is equal to the second distance; in a non-central region of the microdisplay 10, the dimming region 22 is offset toward the central region of the microdisplay 10 by a first distance greater than a second distance. This arrangement ensures that the dimming region 22 is capable of shielding at least a portion of the non-light emitting region and the light transmitting region is capable of shielding at least a portion of the light emitting region.

In practice, for the case that the light beam for imaging emitted by the light emitting unit located in the non-central area of the micro display is emitted to the central area far away from the micro display, the dimming area is shifted to the outside of the micro display (i.e., the edge of the micro display), and the first distance needs to be set smaller than the second distance.

In fig. 6, the micro display corresponds to only one light gathering center, which is a central area of the micro display, and this is only a specific example of the present application and not a limitation of the present application. In practice, the micro display screen can be further provided with a plurality of light gathering centers, and the position of the light gathering centers relative to the micro display screen is not limited. For this case, the magnitude relation between the first distance and the second distance needs to be determined according to the axis extending direction of the light beam for imaging of each light emitting unit in the micro display screen.

It should be noted that, in practice, the light emitting units in the micro display are arranged in various ways, and are not limited to the structure shown in fig. 1. In practice, the dimming film needs to be matched with the arrangement of the light emitting units in the micro display. Fig. 8 is a schematic structural diagram of another micro display provided in an embodiment of the disclosure. Fig. 9 is a schematic view of a structure of a dimming film matched with fig. 8.

Fig. 10 is a schematic structural diagram of another dimming film according to an embodiment of the present disclosure. Fig. 11 is a schematic structural diagram of the micro display in fig. 1 and the dimming film in fig. 10 after being overlapped. Referring to fig. 10 to 11, in the dimming film 20, a plurality of dimming regions 22 are spaced apart, and a light transmitting region 21 surrounds each dimming region 22. This arrangement does not completely block the non-light emitting area, but it cuts the non-light emitting area from a line to a dot, and also improves or eliminates the screen effect because the resolution of the dot by the human eye is less than the resolution of the line.

In the above embodiments, the microstructure is only located on the side of the dimming film close to the micro display screen, which is only a specific example of the present disclosure, and not a limitation of the present disclosure. Optionally, the microstructure is located at a side of the dimming film close to the micro display screen; and/or the microstructure is positioned on one side of the dimming film away from the micro display screen. That is, the microstructure may be formed only on one side of the light control film, or may be formed on both sides of the light control film. If the microstructure is manufactured on one side of the dimming film, the microstructure can be positioned on one side of the dimming film close to the micro display screen, or on one side of the dimming film far away from the micro display screen.

Further, in practice, the dimming film may be in direct contact with the micro display screen or may be spaced apart from the micro display screen by a certain distance.

In one embodiment, if the micro display screen is a self-luminous screen, the display device includes a screen cover plate; the dimming film is positioned between the screen cover plate and the micro display screen. The screen cover plate can be used for protecting the dimming film, so that the dimming film is prevented from being damaged.

Further, the bezel may be multiplexed as a base film in the dimming film. I.e. the microstructure is directly made on the cover plate, so that the thickness of the display device can be reduced.

The embodiment of the disclosure also provides an augmented reality display device, which comprises any one of the display devices provided by the embodiment of the disclosure.

The augmented reality device is a terminal for realizing a virtual effect or a terminal for realizing an effect combining a real effect and a virtual effect, and may be generally provided in the form of glasses, a head mounted display (Head Mount Display, HMD), or a contact lens for realizing visual perception and other forms of perception, but the form of realization of the augmented reality device is not limited thereto, and may be further miniaturized or enlarged as needed.

Optionally, the augmented reality device comprises a virtual reality device and an augmented reality device.
