Description
Technical Field

Background
With the continuous development of display technology, more and more wearable display devices are favored by people. Among them, wearable display devices that are more popular in the market belong to Virtual Reality (visual Reality) display devices and Augmented Reality (Augmented Reality) display devices.
The VR equipment and the AR equipment can realize three-dimensional display, because when human eyes watch objects, the positions of the two eyes are different, so that certain parallax exists between images watched by the two eyes, and the brain fuses the two slightly different images to watch a three-dimensional picture. The VR device displays different images for the left eye and the right eye of the viewer respectively by using the principle of binocular vision, and the different images viewed by the two eyes can generate parallax, thereby generating stereoscopic impression.
However, when the human eyes watch real objects, relative distances exist between the objects, and the brain adjusts the focal lengths of the human eyes when watching different objects, so that when watching distant objects, nearby objects become blurred due to the defocusing of eyeballs; when viewing near objects, distant objects are also blurred. However, when a screen of the VR device is viewed, the distance between the screen and the eyeball is constant, that is, the focal point is kept constant for a long time, different images bring different "depth of field" information, and the focal distance of the eyeball is not adjusted correspondingly, so that discomfort symptoms such as dizziness, nausea, vomiting and the like are easily caused when the balance of the visual system is broken.

Detailed Description
Aiming at the problem of viewing discomfort in the prior art, the embodiment of the invention provides a display device and near-eye wearable equipment.
The following describes in detail specific embodiments of a display device and a near-eye wearable device according to an embodiment of the present invention with reference to the drawings. The thicknesses and shapes of the respective components in the drawings do not reflect the true scale of the display device, and are merely intended to schematically illustrate the present invention.
As shown in fig. 1, a display device provided in an embodiment of the present invention includes: a plurality of display units 100 distributed in an array. Wherein, the enlarged side view of the display unit 100, as shown in fig. 2 a:
the display unit 100 includes: the display device comprises a transparent substrate 101, a display pattern block 102 and a micro lens 103, wherein the display pattern block 102 is positioned on the side of the transparent substrate 101 facing away from a viewer, and the micro lens 103 is positioned on the side of the transparent substrate 101 facing the viewer.
The display device provided by the embodiment of the invention can be used for virtual reality/augmented reality display, and both the two display devices belong to near-eye display devices, namely the display devices are close to human eyes, but the human eyes have a clear distance, so that things which are too close to the human eyes can be generally seen clearly, and the things which are too close to the human eyes can be generally seen clearly only at a distance of more than 25 cm. When the display screen is positioned 25cm beyond the human eye, the display device will be very large, and therefore a lens with a magnifying effect is usually placed in front of the display screen. In the display device provided in the embodiment of the present invention, the display screen is divided into a plurality of display blocks, and the lenses are arranged as the microlens arrays corresponding to the display blocks one by one, so that the display unit 100 including the plurality of display blocks 102 and the microlenses 103 can be obtained to constitute the display device.
The structure of the display device is schematically shown in fig. 2b, in which the same transparent substrate is used as the transparent substrate 101 of each display unit 100, and the display blocks 102 of each display unit 100 are disposed on the same side of the transparent substrate and located on the side of the transparent substrate away from the viewer. The microlenses 103 corresponding to each display tile 102 are located on the other side of the transparent substrate, forming a microlens array on the viewer-facing side of the transparent substrate. In practical application, each display block 102 and each microlens 103 can be directly attached to a transparent substrate, each microlens in the microlens array is a convex lens, and a plano-convex lens can be selected for manufacturing, as shown in fig. 2a and 2b, generally, the microlens 103 can be arranged 1-1.5cm in front of a human eye, the display block 102 can be arranged 3-6cm away from the microlens, and at this time, a virtual image formed by the microlens can be arranged 25-50 cm in front of the human eye, so that the requirement of the human eye photopic distance is met.
Further, when the display device provided by the embodiment of the present invention is used to display an image, the display images of the display blocks 102 are imaged into a same virtual image through the corresponding microlenses 103, and are viewed by a viewer. Specifically, as shown in fig. 3a, for one display unit 100, according to the convex lens imaging principle, the image displayed by the display tile block 102 located within the focal length of the microlens 103 is AB, and after passing through the microlens 103, the virtual image a 'B' is formed, and the light emitted from the point a or B that enters the microlens 103 perpendicularly exits to the focal point F after passing through the microlens 103; and the ray s emitted from point A and passing through the central point O of the optical axis of the microlens 1031And a light ray s emitted from point B and passing through the center point O of the optical axis of the microlens 1032Is not changed, whereby the image observed by the human eye is formed by the intersection of the oppositely extending lines of the refracted rays in the figureA virtual image.
Then, in the above display device provided in the embodiment of the present invention, a plurality of display units 100 are included, where display tiles 102 of the plurality of display units 100 display the same display screen, and images displayed by each display tile 102 are imaged as the same virtual image through a corresponding microlens 103, and an imaging optical path diagram of the image is as shown in fig. 3 b: as can be seen from the above analysis, the propagation direction of the light emitted from the pixel point a (i.e., the light emitting point) in the display block to the optical axis center of the corresponding microlens does not change, and the positions of the display blocks displaying the same image are different from each other, as shown in fig. 3b, when the pixel point a in each display block passes through the optical plum axis center point of the corresponding microlens, the propagation direction of the light does not change, and the reverse extension lines of the light intersect at the point a'. When a viewer watches the display device, the observed point a' is a virtual image point formed by light rays emitted by each display unit from each direction and entering human eyes, and the imaging of the pixel point B in each display image block is similar to that of the point a, which is not described herein again. Therefore, when the human eyes watch the display image in the display image block, each imaging point of the display image can be formed by converging the reverse extension lines of the light rays from all directions like the above, so that the human eyes can watch the real object more closely when watching the image, namely, the light rays are subjected to diffuse reflection on the surface of the object and then enter the human eyes in all directions, the problem of watching discomfort can not occur, and the watching experience of the viewers is effectively improved.
From the above analysis, in order to improve the viewing experience of the viewer, the larger the number of display blocks displaying the same image, the larger the angle of the emergent light of the same image point, the closer to the scattering of the object. However, in order to achieve the purpose that the light is directly emitted without deflection, the light needs to pass through the optical axis center of the microlens, and therefore, the positional relationship between each display block 102 and the corresponding microlens 103 should satisfy that the connection line between each imaging point in the virtual image and the pixel point corresponding to the imaging point in each display block 102 respectively passes through the optical axis center point of the microlens corresponding to each display block, as shown in fig. 3 b. Taking the case shown in fig. 3B as an example, because the connecting line between the point a 'and each point a and the connecting line between the point B' and each point B need to pass through the optical axis center point of the corresponding microlens, the degree of the misalignment between the display pattern blocks located at the two sides and the corresponding microlenses is greater, and the degree of the misalignment between the display pattern blocks located at the center and the microlenses is smaller.
Because the connection between the luminous pixel point and the corresponding imaging point must pass through the optical axis central point of the corresponding microlens, in practical application, the position of the virtual image can be positioned at a position where human eyes can watch more comfortably by adjusting the relative distance between the microlens 103 and the display image block 102. Specifically, as shown in fig. 3b and 3c, the distance between the microlens 103 and the display tile 102 in fig. 3b is smaller than the distance between the microlens 103 and the display tile 102 in fig. 3c, and as can be seen in fig. 3b and 3c according to the above-described imaging principle, the distance between the position of the virtual image formed in fig. 3b and the viewer (human eye) is significantly smaller than the distance between the position of the virtual image formed in fig. 3c and the viewer. Thus, the distance between the virtual image of the microlens array and the viewer increases as the distance between the display tile 102 and the microlens 103 increases. In a specific application, the distance between the display block 102 and the microlens 103 may be smaller than the focal length of the microlens 103 or larger than the focal length of the microlens 103, in addition, the display block 102 may also be located on the focal plane of the microlens 103, and usually, the distance between the display block 102 and the microlens 103 may be set between 0.5 times of the focal length of the microlens 103 and 3 times of the focal length, and the viewing effect of the viewer is better.
As a preferred implementation manner, in the display device provided in the embodiment of the present invention, the images displayed by the display tiles 102 are the same. When all the display blocks 102 display the same image, the number of light rays incident to human eyes in different directions is increased, and the incident angles that can be achieved are also more diversified, so that the image viewed in the field of view of the human eyes is more vivid, and the viewing experience can be improved to the best. In order to achieve higher resolution, it is necessary to make the pixels in the display blocks small enough, and at the current process level, each display block includes hundreds of pixels, and thousands or more pixels are made in the display blocks with the same area as the process level is continuously increased, so as to achieve high resolution display. In practical applications, each display unit of the display device may be divided into several regions, and the display tiles in each region are combined to display the same image, for example, as shown in fig. 4, each display unit is divided into S1, S2, S3, S4, S5 and S6, and the images displayed in each display region of S1 to S6 are the same. When the display mode is adopted, the problem of viewing discomfort can be still reduced to a certain extent, but the effect is relatively weaker compared with the case that all the display image blocks display the same image. The former setting may be preferred in practical applications.
Since the positions of the display blocks 102 and the microlenses 103 in each display unit 100 need to be determined according to the displayed image and the imaging position, in order to avoid the imaging crosstalk between two adjacent display units 100, a certain distance may be set between the display blocks 102, as shown in fig. 2 b. The arrangement can ensure that the light emitted by the display pattern block can only enter the corresponding micro lens for imaging, thereby avoiding the occurrence of imaging crosstalk caused by the fact that the light emitted by the display pattern block enters the adjacent micro lens due to overlarge emergent angle. In addition, gaps among the display blocks have light transmission, when the display device is used as virtual reality display equipment, human eyes can watch external environment scenery through the gaps, and the display effect of augmented reality can be achieved by combining images displayed by the display units.
Further, for convenience of manufacturing, the sizes of the microlenses in the display device provided in the embodiment of the present invention may be the same, and at this time, when the distance between two adjacent display blocks is implemented specifically without avoiding the imaging crosstalk, the minimum distance between two adjacent display blocks may be set to 10% of the maximum width of the microlens, but in practical applications, the distance setting between the display blocks should be determined in combination with the size of the microlens, the size of the display block, the imaging position, and the like, so that the embodiment of the present invention does not limit the specific value of the gap between the display blocks.
In order to better realize augmented reality display, the pixels in the display blocks can be set as transparent pixels. The external environment light can be incident to human eyes from the rear side of the display device through the gaps between the transparent pixels and the display image blocks, and the display effect of augmented reality is achieved.
In the display device provided in the embodiment of the present invention, each display block may adopt a liquid crystal display or an organic light emitting diode display. When the organic light-emitting diode display screen is adopted, the display picture block can be made into a flexible transparent display screen, so that the display device is suitable for various bendable conditions.
To sum up, the display device provided by the embodiment of the present invention integrates virtual reality display and augmented reality display, and arranges a plurality of arrays at each position in a viewing field, so that each microlens images a corresponding display image block as a same virtual image, and the virtual images are formed by converging extension lines of light rays in each direction, so that when a human eye watches such virtual images, the received light rays can come from each direction, and are closer to light rays in each direction scattered by an object when the human eye watches a real object, thereby eliminating the problem of viewing discomfort of the viewer, and improving viewing experience.
Based on the same inventive concept, the embodiment of the invention provides a near-eye wearable device, which comprises any one of the display devices. In particular, the near-eye wearable device may be virtual reality glasses or a virtual reality helmet, and may also be other virtual reality or augmented reality display devices manufactured according to the principles of the present invention.
For example, when the near-eye wearable device provided by the embodiment of the present invention is a virtual reality glasses, as shown in fig. 5a and 5b, the transparent substrate 101 can be used as a lens of the virtual reality glasses, and the micro-lenses 103 are disposed inside the lens, i.e. on the side facing the human eye, to form a micro-lens array, as shown in fig. 5 a; and, the display blocks 102 corresponding to the micro lenses 103 one-to-one are disposed on the outer side of the lens, i.e. the side facing the external environment, as shown in fig. 5b, so that when the virtual reality glasses provided by the embodiment of the present invention are worn, the viewed image is closer to the real object, and no discomfort reactions such as dizziness, nausea, vomiting, etc. are generated.

Because the display element is the array distribution, then each position of microlens in each display element all has the distribution in the visual field, and each microlens is the same virtual image with the demonstration picture block formation of image that corresponds, the virtual image that becomes assembles for the extension line of the light of all directions and forms, so people's eye is when watching such virtual image, received light can come from all directions on, more be close to people's eye the light of all directions that the object scatters when watching real object, thereby will not appear again watching uncomfortable problem, promote and watch experience.
