The prism is arranged on one side of the display device, a coated reflecting surface is arranged on one side of the prism opposite to the display device, and a light splitting surface is obliquely arranged in the prism.
When the intelligent glasses work, the display device displays and emits light ①, light ① emitted by the display device is incident into the prism and transmitted to the splitting surface, light ① incident to the splitting surface is divided into two parts by the splitting surface, wherein one part of the light ① penetrates through the splitting surface and is emitted to the coated reflecting surface to form light ②, the other part of the light ① is reflected by the splitting surface to form light ③, the light ② incident to the coated reflecting surface is divided into two parts, wherein one part of the light is reflected back to the splitting surface to form light ① 1, the other part of the light ② penetrates through the coated reflecting surface to form light ①, the light ① incident to the splitting surface is divided into two parts, wherein one part of the light 5966 penetrates through the splitting surface to form light ① to the display device, the light which does not affect the display device to emit light ① is incident to the prism, the other part of the light ④ is reflected by the splitting surface to form light ①, the light ① is emitted to the eye of the wearer, and is emitted to the eye 7379 of the wearer, thereby enabling the display device to display contents to be virtually observed on the screen.
In the specific embodiment of the invention, the display screen of the display device is a flexible display screen, the material of the display screen can be, but is not limited to, flexible L CD or flexible O L ED, so as to facilitate the adjustment of the curvature of the display screen.
In an example, fig. 3-1 is a schematic structural diagram of a display device according to an embodiment of the present invention, as shown in fig. 3-1, the display device includes a telescopic device 24, a fixing plate 21, a supporting plate 22, and a display screen 23. The display screen 23 is disposed on the support plate 22. The middle part of the display screen 23 is connected with the fixing plate 21, and the center of the display screen 23 is fixed by the fixing plate 21, so that the whole display screen 23 is driven to move when the telescopic device 24 moves. The telescoping devices 24 are disposed at the edges of the display screen 23, and in one example, the telescoping devices 24 are disposed on the four legs of the display screen 23. In the embodiment of the present invention, the telescopic device 24 is a motor, and the motor is disposed between the support plate 22 and the display screen 23, and is fixed by the support plate 22. The extended end of the motor is fixedly connected with the display screen 23, and the motor moves in a telescopic manner to drive the curvature of the display screen 23 to change.
In one example, the motor performs a telescopic motion according to the control of the controller, so as to move the edge of the display screen. For example, the controller determines the distance that the edge of the display screen actually needs to move according to the determined distance that the edge of the virtual display screen needs to move. And sending an instruction to the motor according to the distance moved by the motor rotating for one circle and the distance actually required to be moved by the edge of the display screen so as to indicate the motor to rotate for a certain number of circles to reach the corresponding moving distance. Therefore, the motor drives the edge of the display screen to move, and the edge of the display screen is bent for a determined distance. The controller may also calculate the distance moved by the motor per unit time of rotation, which is not disclosed in the present invention.
Fig. 3-2 is a schematic structural diagram of a display device after curvature adjustment according to an embodiment of the present invention. As shown in fig. 3-2, the extended end of the telescopic device 24 is connected to the display screen 23. When the protruding end of the telescopic device 24 is raised, the display screen 23 is simultaneously raised along with the telescopic device 24, thereby changing the curvature of the display screen 23. By adjusting the different heights at which the telescopic means 24 are extended, different curvatures of the display screen 23 are adjusted. When the display screen 23 is bent, the light emitted from the display screen 23 is also changed. So that the virtual display screen put into the human eye is also changed.
It should be noted that the number of the telescopic devices arranged on the display screen can be set according to actual needs, and can be respectively installed on two sides of the display screen, or can be respectively installed on the periphery of the display screen. When a plurality of telescopic devices are arranged on the display screen, each telescopic device can be independently controlled, so that the curvature of the display screen can be adjusted more freely, and all telescopic devices can be controlled in a unified manner, so that the structure of the intelligent glasses is simplified.
In order to describe the curvature adjustment of the embodiment of the present invention in more detail, the adjustment process of the present invention is explained below by an example. It should be noted that the following adjustment is only one specific implementation of the present invention and should not be used to limit the present invention. The invention is in the scope of protection of the present invention as long as the method and apparatus for determining the curvature of the display screen and the virtual display screen according to the distance from the eyes to the virtual display screen.
In a specific embodiment of the present invention, the smart glasses are further provided with a detection device. The detection device is used for detecting whether the eyes are positioned on a virtual normal line of the virtual display screen when the display screen is in an initial state. When the eyes are positioned on a virtual normal line of the virtual display screen, the extending distances of the motors on the two sides of the virtual display screen are the same, and the calculation is directly carried out according to the vertical distance from the glasses to the virtual display screen. When the eye is located outside the virtual normal of the virtual display screen, the angle of the eye deviating from the virtual normal needs to be determined according to the detector.
Fig. 4 is a virtual display screen after curvature adjustment is completed when the eyes of the wearer are located on a virtual normal line according to an embodiment of the present invention. As shown in fig. 4, MN corresponds to a virtual display screen projected into the eye of the wearer, said virtual display screen being an 80CM x 35CM screen. Since the length of the virtual display screen is 80CM, that is, the arc length of the circular arc MN formed by the virtual display screen is 80 CM.
In an embodiment of the present invention, the smart glasses further store a vertical distance h1. between the eyes and the virtual display screen, if h1 is 300CM, and the position of the eyes is the center of the circular arc, i.e., O point, the circumference of a virtual circle formed by the circular arc MN formed by the virtual display screen is L2 ═ 2 h1 ×, and when h1 is 300CM, L2 is about 1884 CM.
If the central angle corresponding to any one of the two parts is α, the central angle 2 α corresponding to the circular arc MN of the virtual display screen is (L1/L2) × 360, and the central angle of any one of the two parts is α ═ L1/L2) × 180.
If the intersection point of the virtual normal line and the circular arc MN formed by the virtual display screen is a, that is, the circular arc MN is divided into AN MA circular arc and AN circular arc, if the circular arc MA and the center O form a first triangle, the center AN and the center O form a second triangle, and the first triangle is identical to the second triangle, one of the sides of the first triangle is a line from the top end of the circular arc to the center, that is, AN MO line segment, and the other side is a line bisecting the screen of the circular arc through the center, that is, AN AO line segment, the MO line segment is identical to the AO line segment in length, and the first triangle is bisected perpendicularly by the MA line segment, so that MA is 2 h1 sin (2/α). the tangent line under the circular arc formed by the virtual display screen includes a midpoint a, assuming that the tangent line forms AN acute angle with the line MA is β, and since the sum of ∠ MAO, ∠ and ∠ a is 180 °, therefore, the virtual display screen +2(90- β) is β, and thus the virtual display screen is moved by a distance α:
h3＝h2*sinβ
thus, h3 ═ 2 × h1 × sin2(α/2).
Since the first triangle and the second triangle are the same, the other side of the virtual display screen also needs to be moved by a distance h 3.
In an embodiment of the present invention, there is a certain ratio between the virtual display screen and the display screen, since the virtual display screen is an enlarged image projected by the display screen into the human eye. After the edge of the virtual display screen is determined to move for a certain distance, the edge of the display screen is determined to be the first distance for the initial position of the display screen to move according to the ratio of the size of the virtual display screen to the size of the display screen, and then the telescopic device is controlled to move to drive the display screen to move, so that the purpose that the distance from the eyes of a wearer to any point of the virtual display screen is equal is achieved, and a better display effect is achieved.
In one example, the size of the virtual display screen is 80CM, and the actual size of the display screen is 2CM by 0.875 CM. Thus, the ratio of the virtual display screen to the display screen is 40 times, and the light corresponding to the display screen is amplified by 40 times in the process of being transmitted to the human eyes. After the edge movement distance of the virtual display screen is determined, the movement distance of the edge of the virtual display screen needs to be reduced by 40 times, that is, the distance that the edge of the actual display screen moves relative to the initial position of the display screen. When the edge of the virtual display screen moves by 10CM, the edge of the display screen actually needs to move by 0.25CM through the telescopic device.
The above example is only a specific calculation way for adjusting the display screen and the virtual display screen in the present invention, and is not used to limit the content of the present invention.
In particular embodiments of the present invention, differences exist due to wearing habits of different users and physiological habits of different users. When the eyes are positioned outside the virtual normal of the virtual display screen, the detection device detects the angle of the eyes deviating from the virtual normal of the virtual display screen (the included angle formed by the midpoint connecting line of the eyes and the virtual display screen and the virtual normal). The intelligent glasses can calculate the moving distance of the edge of each side of the virtual display screen according to the detected angle, the distance from the eyes to the virtual display screen and the size of the virtual display screen, so that the distance from the eyes to any point on the virtual display screen is the same, and a better display effect is achieved.
The following describes the automatic adjustment of the smart glasses when the eyes of the observer are outside the virtual normal of the virtual display screen according to a specific embodiment.
Fig. 5 is a diagram of a virtual display screen after curvature adjustment is completed when an eye is outside a virtual normal according to an embodiment of the present invention. As shown in fig. 5, MN corresponds to a virtual display screen projected into the human eye, which is 80CM by 35 CM. Since the length of the virtual display screen is 80CM, that is, the arc length of the circular arc MN is 80 CM. The position of the eye is the center of the circular arc MN, namely the point O.
The vertical distance from the eyes to the virtual display screen is h1., the included angle formed by the deviation of the eyes from the virtual normal line of the virtual display screen is gamma, the included angle formed by the vertical line from the eyes to the virtual display screen and the connecting line of the vertical line from the eyes to the middle point of the virtual display screen is equal to gamma, the vertical line from the eyes to the virtual display screen is parallel to the virtual normal line, the gamma is approximately equal to gamma, the central angle corresponding to the virtual display screen is divided into three parts, namely ∠, ∠α and ∠α', the circumference of a virtual circle formed by the circular arc MN of the virtual display screen is L2 h1 pi, the central angle corresponding to the circular arc of the virtual display screen is (80/L2) 360, and if the intersection point of the vertical line from the eyes to the virtual display screen and the virtual display screen is C, the circular arc MN formed by the virtual display screen is divided into an MC section and a circular arc section 353526, wherein the triangle MCO corresponding to the circular arc of the MC section is a first triangle, and the triangle corresponding to the CN section is a second triangle.
Making a perpendicular bisector of the MC line segment to the first triangle, so that the MC line segment is 2 × h1 × sin ((α +)/2). the arc of the virtual display screen includes a tangent line passing through the point C, assuming that the acute angle formed by the tangent line and the line segment MC is β, and since the sum of ∠ MCO, ∠ CMO and ∠ MOC is 180 °, α + +2(90- β) is 180 °, and β ((α + +180)/2), the length of the virtual display screen on the MC segment side is adjusted:
h3＝h2*sinβ。
the edge of the virtual display screen on one side of the CN segment arc moves by a distance h 3.
The distance from one point on the circle to the center of the circle is both NO and CO in the second triangle, therefore, the length of the NO line segment is the same as that of the CO line segment, the second triangle is an isosceles triangle, the perpendicular bisector of the CN line segment is made on the second triangle, and the CN line segment of 2 × h1 × sin (α) can be obtained1V 2) a tangent line passing through the point C under the arc of the virtual display screen, said tangent line forming an acute angle β with the line segment CN1α again because the sum of ∠ NCO, ∠ CON and ∠ ONC is 180 °, therefore1+2(90－β1) Then β, 180 deg.1＝α1/2. Then, the adjusted distance on the NC arc segment side of the virtual display screen is:
h3’＝h2’×sin(α’/2)。
the edge of the virtual display screen on one side of the NC arc segment moves by a distance h 3'.
In an embodiment of the present invention, there is a certain ratio between the virtual display screen and the display screen, since the virtual display screen is an enlarged image projected by the display screen into the human eye. After the edge of the virtual display screen is determined to move for a certain distance, the edge of the display screen is determined to move for a certain distance according to the ratio of the virtual display screen to the display screen, and then the telescopic device is controlled to move to drive the display screen to move, so that the purpose that the distance from the eyes of a wearer to any point of the virtual display screen is equal is achieved, and a better display effect is achieved.
In one example, the size of the virtual display screen is 80CM, and the actual size of the display screen is 2CM by 0.875 CM. Thus, the ratio of the virtual display screen to the display screen is 40 times, and the light corresponding to the display screen is amplified by 40 times in the process of being transmitted to the human eyes. After the edge movement distance of the virtual display screen is determined, the movement distance of the edge of the virtual display screen needs to be reduced by 40 times, that is, the distance that the edge of the actual display screen moves relative to the initial position of the display screen. When the edge on the arc side of the virtual display screen CM moves by 10CM and the edge on the arc side of the CN provides 5CM, one side of the edge of the virtual display screen CM actually needs to move by 0.25CM through the telescopic device and the other side actually needs to move by 0.125CM through the telescopic device.
The above example is only a specific calculation way for adjusting the display screen and the virtual display screen in the present invention, and is not used to limit the content of the present invention.

The intelligent glasses pre-store information of the size of the virtual display screen. Information of the vertical distance of the eyes to the virtual display screen and the ratio of the size of the virtual display screen to the size of the display screen.
In a specific embodiment of the present invention, the smart glasses may further include a focus adjusting device. When the focal length adjusting device moves a certain distance from the initial position, the vertical distance from the actual eye adjusted by the focal length adjusting device to the virtual display screen needs to be determined according to the moving distance of the focal length adjusting device, the ratio of the virtual display screen to the display screen, and the vertical distance from the eye stored in the smart glasses to the virtual display screen.
