Referring to fig. 1, fig. 1 is a schematic view of human eyes and a receiving optical path, in which fig. 1(a) is a schematic view of a normal human eye imaging an object at infinity, and at this time, the thickness of a crystalline lens is adjusted to be minimum, and parallel light emitted from an object point at infinity can be converged on a retina through the convergence effect of the crystalline lens to form a clear image point. Fig. 1(b) is a schematic diagram of a normal human eye imaging a finite distance object, wherein the thickness of the crystalline lens is increased, and divergent light emitted from the object point is converged on the retina to form a clear image point. Fig. 1(c) is a schematic diagram of an image of a near-sighted eye on a limited distant object, because the lens has a large thickness and cannot be adjusted to a suitable state, divergent light emitted by an object point converges in front of a retina, and the object point cannot be clearly imaged on the retina, so that a diffuse spot is formed. Fig. 1(d) is a schematic diagram of a hyperopic human eye imaging a limited distance object, because the lens has a small thickness and cannot be adjusted to a proper state, divergent light emitted from an object point converges on a retina, and the object point cannot be clearly imaged on the retina, so that a diffuse spot is formed.
In order to solve the problem of myopia or hypermetropia caused by insufficient accommodation capacity of the lens of the human eye, the human eye can wear glasses with certain diopter, for example, as shown in the schematic diagram of figure 1(e) for imaging the object by the myopia human eye after wearing the glasses, the light emitting direction of the object point is modulated by the glasses lens, so that the modulated light meets the accommodation range of the lens of the human eye, and finally, clear imaging can be performed on the retina.
Although wearing glasses with diopter can solve the problem of unclear observed images, the long-term wearing of the glasses can cause visual fatigue and discomfort, and particularly, when a display screen needs to be watched for a long time, the visual effect is more obvious.

Continuing to describe the embodiments of the optical display control method provided in the present application, based on the optical display device provided in any of the foregoing embodiments, the optical display control method of the present application, with reference to fig. 8, fig. 8 is a flowchart of the optical display control method, which may include the following steps:
and S110, acquiring positioning information of the observation point relative to the light-emitting panel.
In this step, the position information of the observation point is mainly determined, that is, the position of the human eye relative to the light-emitting panel when the human eye is located at the observation point is determined.
In one embodiment, for obtaining positioning information, an image of an observation point may be taken with a depth camera; then analyzing the image, and calculating the distance and the angle of the observation point relative to each pixel luminous point of the luminous panel; and finally, obtaining the positioning information of the observation point relative to the light-emitting panel according to the distance and the angle.
And S120, acquiring diopter information.
In this step, diopter (which can be generally used as the power of the glasses) can be directly input or obtained through detection.
And S130, calculating a display pattern which needs to be displayed on the optical microstructure by each pixel luminous point when the luminous panel displays the image to be displayed according to the positioning information and the diopter information, and determining a light transmission angle of a microstructure spatial filter contained in the display pattern.
In one embodiment, after the display pattern is calculated, the display pattern overlapped in each pixel luminous point of the image to be displayed is also acquired; the overlapping display patterns are allocated to different display time slots in a time division manner.
In the embodiment, after the display patterns are obtained through calculation, if some pixel light-emitting points of the same image to be displayed are in different display patterns at the same time, the two patterns cannot be displayed at the same time, so that the different display patterns are displayed in different time slots in a time division manner, and a clear image can be formed in human eyes by using human eye vision residue.

In this step, with reference to fig. 2 and 4, by determining the display pattern, the light transmission angle of the microstructure spatial filter of each pixel light-emitting point can be calculated,
wherein the content of the first and second substances,
is a filter parameter, wherein
The light transmission angle of the microstructure spatial filter is shown, alpha is a coefficient, P is diopter, Q (theta, tau) is positioning position information, theta is an included angle of human eyes relative to the light-emitting panel, and tau is the distance from the human eyes to the light-emitting panel.

And the filter parameters are calculated through positioning information and a refractometer. Therefore, the self-adaptive change adjustment can be carried out on the eyes of the myopia or hyperopia with different positions and diopters, so that the eyes of the myopia or hyperopia with different positions and diopters can clearly image on the retina without wearing glasses.
For the optical path analysis involved in the optical display control method provided in the present application, reference may be made to fig. 9, where fig. 9 is a schematic optical path diagram of optical display control.
When analyzing with reference to fig. 1, as described above, fig. 1(b) is a schematic diagram of a normal human eye imaging a finite distance object, in which the thickness of the crystalline lens is increased, and divergent light emitted from the object point is converged on the retina to form a clear image point. Fig. 1(c) is a schematic diagram of an image of a near-sighted eye on a limited distant object, because the lens has a large thickness and cannot be adjusted to a suitable state, divergent light emitted by an object point converges in front of a retina, and the object point cannot be clearly imaged on the retina, so that a diffuse spot is formed. If the light emitting points of the pixels on the light emitting panel are assumed to display an image to be displayed, each pixel light emitting point is normally clearly imaged on the retina, and a diffuse spot is inevitably formed if the light emitting panel continues to display the image to be displayed in a normal manner due to myopia of human eyes.
Therefore, according to the light path analysis of the upper diagram in fig. 9, M points on the original image cannot be imaged on the retina, referring to the lower diagram in fig. 9, assuming that clear imaging is to be formed on the myopic eye, the intersection point corresponds to the retina after the light path is adjusted, a virtual object point is correspondingly formed at the M point, so that the myopic eye can be imaged clearly, according to the reverse light path, if an object which is clear to the myopic eye is to be generated at the M point, the object is correspondingly displayed as an M' display pattern on the light-emitting panel, the specific shape and the light-emitting direction of the display pattern can be calculated through the positioning information and diopter of human eyes, and therefore, the virtual object point is generated at the M point by controlling the light-transmitting angle of the microstructure spatial filter of the optical microstructure, so that a clear image is formed in the myopic eye.
As shown in fig. 9, it is assumed that a dot is generated at the point M, that is, a dot to be displayed on an image to be displayed is correspondingly a circular ring, and as shown in fig. 10, fig. 10 is an image pattern schematic diagram, at this time, a circular ring can be calculated by combining positioning information and diopter, a black square in the circular ring is a microstructure spatial filter included in a circular ring image pattern, and then, by displaying the circular ring on a light emitting panel, an imaging image of the dot can be formed in a myopic eye, and for eyes with different diopters, only the size of the circular ring needs to be adjusted according to diopter.
In one embodiment, the optical display control method provided by the application can also realize adaptive display control under a plurality of observation points; for example, when two human eyes watch a display screen at the same time, the display control is carried out in different time slots by designing a time division display scheme and utilizing the visual residual of the human eyes, and the time division display scheme is independent and does not interfere with each other.
Based on this, the optical display control method provided by the present application may further include the following scheme:
acquiring positioning information of a plurality of observation points; respectively calculating a display pattern to be displayed on the optical microstructure of each pixel luminous point when the luminous panel displays an image to be displayed according to the positioning information and diopter information of each observation point, and determining a light transmission angle of a microstructure spatial filter contained in the display pattern; and generating filtering parameters according to the display pattern of each observation point and the light transmission angle of each pixel luminous point of the display pattern, and sequentially sending the filtering parameters to the optical microstructure for time division control.
In the above embodiment, referring to fig. 11, fig. 11 is a schematic control diagram in a time division manner, after the light transmission angle of the microstructure spatial filter corresponding to each observation point is determined, the light filtering parameter is transmitted to the optical microstructure, the optical microstructure can control the light emitting direction of the microstructure spatial filter according to the arranged time slots, and since the light is emitted in the designated direction, the human eyes at different observation point positions cannot see the images of other observation points, so that the human eyes are not influenced, and based on the characteristic of the visual residual of the human eyes, the human eyes cannot feel the switching process between different time slots.
In an embodiment, according to the technical scheme provided by the application, when a user cannot know diopter information, the user can also use an optical display device to perform measurement, taking a flat panel as an example, referring to fig. 12, where fig. 12 is a schematic diagram of diopter measurement performed by the optical display device, in an implementation process, a myopic eye is positioned first, and then a background performs real-time calculation according to a relational formula of "filtering parameter-diopter-positioning position", for example, the user can set diopter P to a digital range (120, 500), then select diopter in the range to perform calculation, from small to large, at this time, the myopic eye stares at a display screen, when the image observed by the eye becomes clear, the user clicks to determine, and the background records corresponding diopter, which is stored as the diopter of the myopic eye.
