Background
The eye mainly comprises a lens and a retina, wherein the lens can be equivalently a convex lens with a variable focal length, and has a converging function on light, so that the light emitted by the same object point is converged on a vision screen to form an image point, and the normal glasses can realize clear imaging of the object point at the position from infinity to 10cm by adjusting the thickness of the lens.
Referring to fig. 1, fig. 1 is a schematic diagram of a human eye and a receiving light path, wherein fig. 1 (a) is a schematic diagram of a normal human eye imaging an infinitely distant object, at this time, the thickness of a lens is adjusted to be minimum, and parallel light emitted from the infinitely distant object point can be converged on a retina by a converging action to form a clear image point. Fig. 1 (b) is a schematic diagram of a normal human eye imaging a limited distance object, in which the lens thickness increases, 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 eye of a myopic eye imaging a limited distance object, and because the lens has a large thickness and cannot be adjusted to a proper state, divergent light emitted from an object point is converged in front of a retina, and the object point cannot be imaged clearly on the retina, so that a diffuse spot is formed. Fig. 1 (d) is a schematic diagram of far vision imaging of a limited distance object, and because the lens thickness is small and cannot be adjusted to a proper state, the diverging light emitted by the object point will be converged on the retina, and the object point cannot be imaged clearly on the retina, so as to form a diffuse spot.
In order to solve the problem of myopia or hyperopia caused by insufficient thickness adjustment capability of the lens of the human eye, glasses with a certain diopter can be worn, as shown in fig. 1 (e), the myopic eye images an object schematically, and the luminous direction of the object point is modulated by the glasses lens, so that the modulated light meets the adjustment range of the lens of the human eye, and finally, clear imaging can be performed on the retina.
Although wearing glasses with diopters can solve the problem of unclear observation images, long-term wearing can lead to visual fatigue and uncomfortable feeling, and particularly when a display screen is required to be watched for a long time, the influence on vision is more obvious.

The following further describes an embodiment of the optical display control method provided in the present application, based on the optical display device provided in any of the foregoing embodiments, with reference to fig. 8, fig. 8 is a flowchart of the optical display control method, and may include the following steps:
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 with respect to the light emitting panel when the human eye is located at the observation point is determined.
In one embodiment, for obtaining positioning information, a depth camera may be utilized to capture an image of the observation point; then analyzing the image, and calculating the distance and angle of the observation point relative to the luminous point of each pixel of the luminous panel; and finally, positioning information of the observation point relative to the light-emitting panel is obtained according to the distance and the angle.
S120, diopter information is obtained.
In this step, the diopters (typically the spectacle power) can be directly input or detected.
S130, calculating a display pattern to be displayed on the optical microstructure of 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 the light transmission angle of the microstructure space filter contained in the display pattern.
In one embodiment, after calculating the display pattern, the display pattern overlapped in each pixel luminous point of the image to be displayed is also obtained; the overlapping display patterns are arranged in a time division manner into different display slots.
In this embodiment, after the display patterns are obtained through calculation, if some pixel luminous points of the same image to be displayed are simultaneously in different display patterns, two patterns cannot be displayed at the same time, therefore, different display patterns are displayed in different time slots in a time division manner, and a clear image can be formed in the human eye by utilizing human eye vision residues.
And S140, generating a filtering parameter according to the display pattern and the light transmission angle of each pixel luminous point thereof, and transmitting the filtering parameter to the optical microstructure.
In this step, with reference to fig. 2 and 4, by determining the display pattern, the light transmission angle of the spatial filter of the microstructure of the light emitting point of each pixel can be calculated,
wherein (1)>
Is a filtering parameter, wherein->
Is the light transmission angle of the microstructure space filter, alpha is a coefficient, P is diopter, Q (theta, tau) is positioning position information, theta is the 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.
According to the optical display control method provided by the embodiment, by the optical display device, when a near-sighted or far-sighted human eye views a display screen, the image can be clearly formed on the retina without wearing glasses, and the application experience is enhanced. And the filter parameters are calculated by the positioning information and diopter. Therefore, the self-adaptive change adjustment can be carried out on the myopia or hyperopia eyes with different positions and different diopters, so that the myopia or hyperopia eyes with different diopters at different positions can be clearly imaged 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, and fig. 9 is a schematic optical path diagram of optical display control.
As described above in connection with fig. 1, fig. 1 (b) is a schematic diagram of a normal human eye imaging a limited distance object, where the lens thickness increases, so that divergent light emitted from the object point is focused on the retina to form a clear image point. Fig. 1 (c) is a schematic diagram of an eye of a myopic eye imaging a limited distance object, and because the lens thickness is large, the lens cannot be adjusted to a proper state, so that divergent light emitted from an object point is converged in front of a retina, and the object point cannot be imaged clearly on the retina, so that a diffuse spot is formed. Assuming that the pixels on the light-emitting panel emit light, if an image to be displayed is displayed, it should be that each pixel should be clearly imaged on the retina normally, and if the light-emitting panel continues to display the image to be displayed in a normal manner, a diffuse spot is necessarily formed due to myopia of human eyes.
Therefore, according to the light path analysis of the upper graph in fig. 9, the M point on the original image cannot be imaged on the retina, referring to the lower graph in fig. 9, if clear imaging is to be formed on the near-sighted eye, the light path is adjusted, and then the intersection point corresponds to the retina, a virtual object point is formed at the corresponding M point, so that the near-sighted eye can be clearly imaged, according to the reverse light path, if an object for making the near-sighted eye see clearly is 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 the human eye, 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 the clear image is formed in the near-sighted eye.
In fig. 9, it is assumed that a dot is generated at M points, that is, a dot to be displayed on an image to be displayed, and a display pattern to be displayed on an optical microstructure is a ring correspondingly, referring to fig. 10, fig. 10 is a schematic diagram of an image pattern, at this time, a ring can be calculated by combining positioning information and diopter, a black box in the figure is a microstructure space filter included in the ring image pattern, and then an imaging image of the dot can be formed in a myopic eye by displaying the ring on a light-emitting panel, and the eyes with different diopters only need to adjust the size of the ring according to diopter.
In one embodiment, the optical display control method provided by the application can also realize adaptive display control under multiple observation points; for example, when two eyes watch the display screen at the same time, the time division display scheme is designed, so that the vision residues of the eyes are utilized to perform display control in different time slots, and the eyes are independent of each other and do not interfere with each other.
Based on this, the optical display control method provided in the present application may further include the following scheme:
acquiring positioning information of a plurality of observation points; 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 the light transmission angle of a microstructure space filter contained in the display pattern; and generating filter parameters according to the display patterns at each observation point and the light transmission angles of the luminous points of each pixel, and sequentially sending the filter parameters to the optical microstructure for time division control.
In the above embodiment, referring to fig. 11, fig. 11 is a schematic diagram of time division control, after the light transmission angle of the micro-structure spatial filter corresponding to each observation point is determined, the optical micro-structure transmits the light filtering parameters to the optical micro-structure, so that the optical micro-structure can control the light emitting direction of the micro-structure spatial filter according to the arranged time slots, and since the light is emitted towards the designated direction, the eyes at the positions of different observation points cannot see the images of other observation points, so that the eyes are not affected at all, and the eyes cannot sense the switching process between the different time slots based on the characteristics of the vision residues of the eyes.
In an embodiment, when the user cannot know the diopter information, the technical scheme provided by the application can also use the optical display device to measure, taking the flat panel electricity as an example, referring to fig. 12, fig. 12 is a schematic diagram of the optical display device to measure diopter, in the implementation process, the myopic eye is positioned first, then the background calculates in real time according to the relation formula of the filtering parameter-diopter-positioning position, for example, the user can set diopter P to be a digital range (120, 500), then the diopter is selected in the range to operate, from small to large, at this time, the myopic eye stares at the display screen, when the image is observed to be clear, clicking is determined, the corresponding diopter is recorded in the background, and the diopter is stored as the diopter of the myopic eye.
