the arc-shaped display systems 1-7 are positioned in the focal plane range of 1cm of the spherical reflector 2, the distance between the arc-shaped display systems and the transparent protective layer 7 is less than 1cm, and light rays emitted by the arc-shaped display systems enter human eyes after being reflected by partial reflecting surfaces of the spherical reflector 2; the width of the arc-shaped display systems 1-7 is preferably smaller than the minimum value of the pupils of human eyes, and is preferably smaller than 2mm, and the arc-shaped display systems can be in any shape.
The luminous pixel units in the arc-shaped display systems 1-7 are randomly distributed on the arc-shaped display systems 1-7; the arc-shaped display systems 1-7 drive the rotor permanent magnet 9 through the stator driving coil 8, the sliding bearings 10 are linked to rotate to refresh the whole picture, and the display function is realized through the visual persistence effect.
In this embodiment, the wireless data receiver 11 can receive the image information to be displayed in a wireless manner, and the commonly used wireless technologies include UWB, WiFi, infrared, LiFi, millimeter wave, and other wireless technologies.
In the present embodiment, the wireless transmission of data is also realized by the induction coil 14 and the signal transmission slot 15, and as shown in fig. 7, image information is generally transmitted by a multiplex transmission line, the induction coil 14 is placed at the center of the signal transmission slot 15, in close proximity (<0.5mm) to both walls of the signal transmission slot 15 without physical contact therewith, and the induction coil receives data transmitted from the signal transmission slot 15 by electromagnetic induction.
In this embodiment, the detector 12 is capable of detecting information about the target 13 to determine the rotational speed and position of the arc-shaped display system 1-7. The detector 12 may be an infrared detector, a hall sensor, or the like. The target 13 may be an infrared emitter or a small magnet.
Referring to fig. 8 to fig. 11, the arc display system 1-7 is located within 1cm near the focal plane of the spherical mirror 2, and the emitted light enters the human eye after being reflected by a part of the reflective surface of the spherical mirror 2. In order to not block the reflected light, the width of the arc-shaped display system 1-7 is smaller than the diameter of the pupil of the human eye. Preferably, the width is less than 1 mm. As shown in fig. 8, in the arc-shaped display system 1-7, the light-emitting pixel units are distributed according to a specific shape, and the arc-shaped display system 1-7 is arranged by aligning multiple rows of red, green and blue mixed pixel units 1-7-1 (fig. 8 a).
In this embodiment, when a row of rgb mixed pixel units 1-7-1 is distributed on each arc-shaped display system 1-7, the rgb mixed pixel units 1-7-1 between adjacent strips are separated by at least two pixel units, and the separated positions between adjacent strips are arranged in a staggered manner.
When multiple rows of red, green and blue mixed pixel units 1-7-1 are distributed on each arc-shaped display system 1-7, at least two pixel units are arranged at intervals of the red, green and blue mixed pixel units 1-7-1 in each arc-shaped display system 1-7, and the adjacent rows are arranged in a staggered mode. The integrity of the rotated picture is guaranteed.
In order to increase the density of the pixel units, when the pixel units are arranged in each circle, the red pixel units 1-7-2, the green pixel units 1-7-3 and the blue pixel units 1-7-4 are arranged according to a rotating track (fig. 8b), firstly, patterns to be displayed are decomposed according to three primary colors, then, the light intensity displayed on the corresponding position of each color in space is independently driven, and due to the persistence of vision effect, the superposition of different colors of the pixel units which rotate rapidly at different times can also form the required color at the same position.
As shown in fig. 9a, the red pixel units 1-7-2, the green pixel units 1-7-3, and the blue pixel units 1-7-4 are respectively arranged on each arc-shaped display system 1-7 at intervals of 120 °, and a color picture can be formed through rapid rotation and persistence of vision. Obviously, more line shaped display systems arranged at equal angles can be used, as shown in fig. 9 b.
As shown in fig. 10, since the tracks of each pixel unit are concentric circles, the arrangement of the pixel units can be designed, so that the distance between the pixel units is increased, and then the pixel units are filled with a plurality of pixel units, thereby achieving high density and reducing the manufacturing difficulty. In fig. 10a, two rows of red, green and blue mixed pixel units 1-7-1 are adopted, the pixel units are arranged at the intersection points between the row tracks and the concentric circles, and the pixel units in each row are separated by one intersection point. In this arrangement, the distance between pixel cells is increased, but the pixel cell density of the display is not visually reduced after the display is refreshed by the rotational scanning. In fig. 10b, four independent arc-shaped display systems 1-7 are adopted, each display system is provided with a row of red, green and blue mixed pixel units 1-7-1, the pixel units in each row can be separated by 3 pixel units, and when the display is rotated and refreshed, the density of the spatial pixel units is not reduced.
In the rotating display system, the length of an arc swept by the edge is longer than that of the center, and if the number of pixel units at the edge is the same as that of the center, in the rotating refreshing display imaging, the density of the pixel units displayed at the edge is lower than that of the pixel units displayed at the center, so that the requirement on the refreshing rate of the display system is higher. When the refresh rate of the display system is insufficient, a fan-shaped slit which diverges outward from the center of a circle may be generated, and the problem of dark edge and bright center may also occur, which affects the image display quality. To solve this problem, as shown in fig. 11, the number of pixel units on each concentric circle is gradually increased as the distance of the pixel units from the rotation center is farther, so as to improve the display quality of the edge and reduce the refresh rate requirement of the display system. Similarly, there may be two (FIG. 11a), four in a cross arrangement (FIG. 11b), or multiple in an equiangular arrangement throughout the system.
In this embodiment, the method for optimizing downward compatibility of the display system with the low-performance host includes:
the arc length of the arc-shaped display systems 1-7 is related to the viewing angle, and the longer the arc length is, the larger the viewing angle is; with the same arc length, the pixel cell density is related to the resolution, with higher pixel cell densities giving higher resolutions.
In order to be compatible with a plurality of different performance main computing units, therefore, the same arc-shaped display system 1-7 can dynamically adjust the resolution and the field angle according to the computing power of different computing units. The design is as follows:
the angle of view and the resolution of the initial design of the arc-shaped display systems 1 to 7 are preferably used by being paired with a high-performance main computing unit, and support the main computing unit with relatively weaker downward compatibility, and the maximum angle of view and the maximum resolution parameters of the design of the arc-shaped display systems 1 to 7 are set as system standard values by default.
When the augmented reality glasses are matched with a main computing unit with weaker performance and the performance of the main computing unit cannot meet the resolution or the angle of view parameter set by the system standard value of the arc-shaped display system 1-7, rendering and displaying are carried out in the following mode:
1. only the angle of view is reduced, and the pixel unit density is not reduced. The main computing unit reduces the field angle of the rendered image to reduce the amount of data for image rendering, and the arc-shaped display system 1-7 also reduces the display area arc length, i.e. the arc-shaped display system 1-7 does not light up the pixel cells of missing pixel cell data when rotating the refresh image.
2. Only the pixel unit density is reduced, and the field angle is not reduced. The main computing unit reduces the amount of rendered data by reducing the pixel cell density of the image rendering, while the arc-shaped display system 1-7 does not light up the pixel cells with missing pixel cell data when the image is rotated and refreshed.
3. Both the field angle and the pixel cell density are reduced. The main computing unit reduces the radius of an image rendering field angle, simultaneously reduces the density of pixel units of the image rendering, and simultaneously, the arc-shaped display systems 1-7 do not light up the pixel units with missing pixel unit data when rotating and refreshing images.
In the present embodiment, the adjustment design for the refractive power is as follows: the radian of the inner side 7-1 of the transparent protective layer close to human eyes in the transparent protective layer 7 can be adjusted correspondingly according to the degree of a user. The curvature of the outer side 7-2 of the transparent protective layer can also be adjusted, preferably the shape of the outer side 7-2 of the transparent protective layer conforms to the shape of the display system 1. If the wearer is near sighted, the inner side 7-1 of the transparent protective layer is adjusted to ensure that the two sides of the transparent protective layer 7 are thick and the middle is thin, and if the wearer is far sighted, the two sides are thin and the middle is thick.
The present embodiment will be described with reference to fig. 12 to 14, which further includes a method for designing and manufacturing the arc-shaped display system 1-7 (screen), and is implemented by the following steps:
step one, adopting a silicon substrate 1-7-5 with the thickness less than or equal to 100 micrometers as a substrate of an arc-shaped display system 1-7;
step two, placing a plurality of luminous micro OLED or micro LED units to form control and luminous layers 1-7-6 after manufacturing a control integrated circuit on the substrate in the step one through the processes of photoetching and evaporation;
step three, cutting the luminescent panel produced in the step two into linear luminescent thin strips with the width less than 2 mm;
and step four, placing the linear luminous thin strips obtained in the step three on the required cylindrical surface control substrates 1-7-7, and applying pressure on two sides.
And fifthly, tightly attaching the linear luminous thin strips to the cylindrical surface control substrate 1-7-7 to form the arc-line-shaped display system 1-7.
The other manufacturing method comprises the following steps: as shown in fig. 13, the multi-segment linear sub-display units 1 to 7 to 8 are connected to form a polygon to approximate a desired circle, and the larger the number of segments, the smaller the error. This method can avoid bending process and is easy to manufacture.
As shown in fig. 14, there is a gap at the joint between the multiple segments of linear sub-display units 1-7-8, and due to the limitation of the current production process, the gap may lack a part of light-emitting pixel units, resulting in the incoherence of the arc-shaped display system 1-7, so that the gap at the joint is compensated by adding the linear sub-display compensation units 1-7-9, so as to form a continuous and seamless picture. The manufacturing method can also combine with the pixel unit arrangement mode of fig. 11, and the number of the pixel units on each concentric circle is gradually increased along with the farther the pixel units are away from the rotation center, so that the display quality of the edge is improved.
In this embodiment, the arc-shaped display system allows deformation within 1cm from the ideal spherical surface to achieve the effect of individualization or reduction of manufacturing difficulty, as shown in fig. 15, as shown by the dotted line, the ideal shape 1-11 of the inner spherical surface of the display system, the ideal shape 1-12 of the outer spherical surface of the display system, the theoretical shape 2-5 of the inner side of the spherical mirror, and the theoretical shape 2-6 of the outer side of the spherical mirror are ideal shapes, and as shown by the solid line, the irregular shape 1-9 of the inner side of the display system, the irregular shape 1-10 of the outer side of the display system, the aspherical shape 2-3 of the inner side of the mirror, and the aspherical shape 2-4 of the outer side of the mirror. The optical system according to this embodiment has low sensitivity to tolerance, and preferably, the difference between the deformation value and the ideal shape needs to be less than 0.5 mm.
