The motion state of the AR display device may be a static state or a non-static state, and may also refer to the motion intensity in the non-static state, such as a violent shake, a slight shake, or the like. In addition, it should be noted that the motion state of the AR display device may refer to the motion of the AR display device along with the motion of the user when the user wears and uses the AR display device.

The terms "first," "second," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

AR display devices typically take the form of eyeglasses to be worn by a user.

For example, referring to fig. 1A, fig. 1A provides a schematic structural diagram of an AR display device in the prior art, the AR display device is in the form of glasses, and the AR display device includes a display lens 10 and a main frame 20, the main frame 20 includes a frame 21 and a temple 22, the display lens 10 is used for a user to view an environment of a real world and for displaying an image of a virtual world, and the display lens 10 is generally disposed or fixed by the frame 21, and the temple 22 is used for the user to wear.

Further, with continued reference to fig. 1A, in order to ensure the contrast and the clarity of the display image displayed by the display lens 10 of the AR display device, a light shielding cover 1000 is usually disposed on a side of the display lens 10 away from the temple 22.

Referring to fig. 1B, fig. 1B is a partial cross-sectional structure diagram of the AR display apparatus shown in fig. 1A in a side view direction, showing that the lens 10 includes a first surface 11 and a second surface 12 which are oppositely disposed, the first surface 11 is a surface showing the lens 10 close to the temple 22, and the second surface 12 is a surface showing the lens 10 far away from the temple 22. In order to improve the contrast and the clarity of the display image of the AR display device presented by the display lens 10, a light shield 1000 is generally disposed on the side of the display lens 10 where the second face 12 is located, the light shield 1000 is generally made of a low-transmittance material, and the transmittance of the light shield 1000 is generally low and is generally constant.

The light shield 1000 is used to shield the amount of ambient light incident on the display lens 10 through itself. Under the condition that the brightness of the real world environment is relatively high, the transmittance of the light shield 1000 is relatively low, so that the display lens 10 is in a dark environment, that is, a dark display background is provided for the display picture of the display lens 10, and thus the contrast of the display picture of the display lens 10 and the definition of the display picture can be improved due to the arrangement of the light shield 1000.

The transmittance of the light shield 1000 is low, that is, the transmittance of the AR display device is low, if the transmittance of the AR display device is low, when the user uses the AR display device, the user cannot see the environment of the real world clearly through the display lens 10 and the light shield 1000, and in the using process, the experience of the user is affected.

The transmittance refers to a ratio of radiant energy projected through the object to total radiant energy projected on the object in a process in which the incident light flux is separated from the irradiated surface or the medium incidence surface to the other surface. Specifically, as shown in fig. 1, the transmittance of the light shielding mask 1000 can be understood as the ratio of the radiant energy of the light passing through the light shielding mask 1000 to the surface of the light shielding mask 1000 close to the display lens 10 to the radiant energy of the light irradiating the surface of the light shielding mask 1000 far from the display lens 10.

With continued reference to fig. 2B, the display lens 100 further includes an electrochromic layer 120, the electrochromic layer 120 is disposed on the second surface 112 of the display lens 100, and specifically, the electrochromic layer 120 is disposed on the display lens body 110 in a stacked manner. For example, the electrochromic layer 120 may be plated or attached on the second side 112 of the display lens 100, and the AR display device may adjust the transmittance of the display lens 100 by adjusting the transmittance of the electrochromic layer 120.

Further, the display lens body 110 is used for displaying an image, which may be an AR display image (i.e., a virtual scene), and the user can view the external real environment through the display lens body 110. The transmittance of the electrochromic layer 120 is varied according to a voltage variation on the electrochromic layer 120, so that the electrochromic layer 120 serves to adjust the intensity of ambient light transmitted through the display lens body 110 and the electrochromic layer 120.

The transmittance of the electrochromic layer 120 is high, so that the intensity of ambient light passing through the display lens body 110 and the electrochromic layer 120 is high, that is, a user can conveniently view the external real-world environment through the display lens body 110 and the electrochromic layer 120, and the higher the transmittance of the electrochromic layer 120 is, the higher the definition of the external real-world environment viewed by the user through the display lens body 110 and the electrochromic layer 120 is; the transmittance of the electrochromic layer 120 is low, so that the intensity of the ambient light passing through the display lens body 110 and the electrochromic layer 120 is low, a darker display background can be provided for the display lens body 110, the contrast of an image (display picture) relative to the ambient light can be improved, that is, the display contrast of the image can be improved, and the display definition of the image can also be improved.

The transmittance of the electrochromic layer 120 can be adjusted according to the motion parameter for representing the motion state of the AR display device, so that when the AR display device is in the user use state, the transmittance of the electrochromic layer 120 can meet the requirements of the user in different motion states of the user, so as to improve the experience of the user. For example, when a user is in a walking state, in order to enable the user to clearly view the external environment through the display lens 100 and facilitate the user to determine a walking path, the user generally needs to have a higher transmittance of the display lens 100, and then the transmittance of the electrochromic layer 120 may be higher, for example, may be adjusted to 20% or 50%, and the higher transmittance of the electrochromic layer 120 means that the transmittance of the display lens 100 is higher, so that the user experience may be improved. Further, when the user is in a static state, in order to enable the user to watch the display more clearly, the transmittance of the display lens 100 is generally required to be lower by the user, so that the transmittance of the electrochromic layer 120 may be lower, for example, may be adjusted to 4% or 6%, and when the transmittance of the electrochromic layer 120 is lower, a darker display background may be provided for the display lens body 110, thereby the contrast of the display image of the display lens body 110 and the definition of the display image may be improved, and further, the experience of the user may also be improved.

Illustratively, in an embodiment of the present application, the electrochromic layer 120 is made of an electrochromic material, and the transmittance of the electrochromic layer 120 is related to the magnitude of the voltage applied thereto, and the adjustment of the transmittance of the electrochromic layer 120 can be achieved by adjusting the magnitude of the voltage applied to the electrochromic layer 120. Generally, the transmittance of the electrochromic layer 120 is inversely related to the magnitude of the voltage applied thereto, i.e., the higher the voltage, the lower the transmittance of the electrochromic layer 120.

Further, the display lens 100 includes an electrochromic layer 120, and the electrochromic layer 120 may determine the transmittance of the display lens 100. The adjustment of the transmittance of the display lens 100 can be quickly achieved by providing the electrochromic layer 120.

The transmittance of the electrochromic layer 120 is in a positive correlation with the transmittance of the display lens 100, that is, the greater the transmittance of the electrochromic layer 120 is, the greater the transmittance of the display lens 100 is, and vice versa.

Further, the electrochromic layer 120 mainly has two color changing modes, namely, chemical oxidation-reduction reaction electrochromic and liquid crystal electrochromic, wherein the chemical oxidation-reduction reaction electrochromic mainly means that after voltage is applied, chemical substances are changed, so that the transmittance is changed. The liquid crystal electrochromism mainly means that the ion rotation angle of liquid crystal changes after voltage is applied, so that the transmittance is changed.

For example, if the electrochromic layer 120 is a chemical oxidation-reduction electrochromic layer, the electrochromic layer 120 may be made of an inorganic electrochromic material, and the inorganic electrochromic material may be directly plated on the second surface 112 of the display lens body 110. The electrochromic layer 120 made of the inorganic electrochromic material may be formed by plating.

And if the electrochromic layer 120 is a chemical oxidation-reduction electrochromic layer, the electrochromic layer 120 may also be an electrochromic film or thin layer made of an organic electrochromic material, and the electrochromic film or thin layer may be attached to the second surface 112 of the display lens body 110.

For example, referring to fig. 2C, the structure of the electrochromic film or thin layer may include a color-changing layer 1202 and protective layers 1201 located at two sides of the color-changing layer 1202, and the electrochromic film or thin layer is attached to the display lens body 110 through a surface where one of the protective layers 1201 is located, for example, the electrochromic film or thin layer is attached to the second surface 112 of the display lens body 110 as shown in fig. 2B.

The electrochromic film or thin layer made of the organic electrochromic material is arranged on the display lens body 110 in a sticking manner, so that the electrochromic layer 120 can be conveniently replaced.

If the electrochromic layer 120 is liquid crystal electrochromic, the electrochromic layer 120 may be attached to the second surface 112 of the display lens body 110 as shown in fig. 2B.

It should be noted that the display lens 100 may further include other layers besides the electrochromic layer 120, for example, a polarization layer for polarizing incident light to achieve an ultraviolet protection function, which may be disposed as needed, and is not limited in the embodiment of the present application.

In addition, it is understood that layers other than the electrochromic layer 120, which may be included in the display lens 100 of the AR display device, also have specific transmittances of their own. In such a case, the overall transmittance of the AR display device is determined by the transmittance of the above several components as a whole.

In order to further highlight the features and simplicity of the description of the present application, the display lens 100 is described as including only the display lens body 110 and the electrochromic layer 120.

Referring to fig. 2D and fig. 3, fig. 2D is a schematic cross-sectional structural diagram of the AR display device shown in fig. 2A in a top view direction, and fig. 3 is a block diagram of the AR display device according to an embodiment of the present disclosure. In particular, fig. 2D and 3 illustrate schematic views of the internal functional structure of the AR display device associated with the function of adjusting the transmittance of the lens assembly. These functional components can be realized by hardware such as electronic circuits and chips, or by a combination of hardware and software.

In one embodiment of the present application, the AR display apparatus may further include a control part 300, a motion detection part 400, and a power supply part 500 as shown in fig. 2D and 3. The control unit 300 is connected to the motion detecting unit 400 and the power supply unit 500, and the power supply unit 500 is connected to the electrochromic layer 120.

The motion detection part 400 detects the motion state of the AR display device, outputs the motion parameters for representing the motion state of the AR display device based on the motion state of the AR display device, and can quickly and accurately determine the motion state of the AR display device through the motion parameters obtained by detecting the motion state of the AR display device through the motion detection part 400.

The motion detection part 400 transmits the motion parameter to the control part 300, so that the control part 300 determines a first output voltage according to the motion parameter and transmits the first output voltage to the power supply part 500, the power supply part 500 supplies power to the electrochromic layer 120 according to the first output voltage, and the transmittance of the electrochromic layer 120 is adjusted to the transmittance corresponding to the first output voltage. That is, the control part 300 determines and adjusts the voltage output by the power supply part 500 to the electrochromic layer 120 according to the motion parameter to adjust the transmittance of the electrochromic layer 120, and adjusts the transmittance of the display lens 100 by adjusting the transmittance of the electrochromic layer 120, thereby implementing the adjustment of the transmittance of the AR display device.

In some embodiments of the present application, the control part 300, the motion detecting part 400, and the power supply part 500 may be fixed on the aforementioned temples 220. For example, a receiving space may be formed on the temples 220 such that the control part 300, the motion detecting part 400, and the power supply part 500 are mounted (fixed) therein. Also, the accommodating space may be an inner cavity formed on the temples 220, and the control part 300, the motion detection part 400, and the power supply part 500 are installed (fixed) in the inner cavity. Further, the connection structures among the control part 300, the motion detection part 400, the power supply part 500, and the electrochromic layer 120 are also installed (fixed) in the accommodating space.

Of course, referring to fig. 2D, three accommodating spaces, namely a first accommodating space, a second accommodating space and a third accommodating space, may be formed on the glasses legs 220 to respectively arrange the control component 300, the motion detection component 400 and the power supply component 500. In addition, a passage for communicating the first accommodating space, the second accommodating space, and the third accommodating space may be provided for providing a connection structure among the control part 300, the motion detecting part 400, the power supply part 500, and the electrochromic layer 120 in the passage.

The control unit 300, the motion detection unit 400, and the power supply unit 500, and the mounting (fixing) manner of the connection structure among the control unit 300, the motion detection unit 400, the power supply unit 500, and the electrochromic layer 120 may be set as required, and are not limited in the embodiments of the present application.

The control part 300, the motion detection part 400, the power supply part 500 and the electrochromic layer 120 may be connected by an electrical connection wire, that is, the connection structure therebetween may be an electrical connection wire.

If the control unit 300, the motion detection unit 400, the power supply unit 500, and the electrochromic layer 120 are connected by electrical connection lines, the control unit 300, the motion detection unit 400, the power supply unit 500, and the electrochromic layer 12 may be fixed to the same temple 220 to facilitate the connection. Of course, the control part 300, the motion detection part 400, the power supply part 500, and the electrochromic layer 120 may be fixed to different temples 220.

It should be noted that the number, the positions, and the like of the accommodating spaces may be set as needed, and are not limited in the embodiment of the present application.

For example, in an embodiment of the present application, the motion detection component 400 may include an accelerometer, the accelerometer is configured to detect acceleration information of the AR display device when the AR display device is moving, the motion parameter may be acceleration information of the AR display device when the AR display device is moving, and the accelerometer is configured to detect acceleration information of the AR display device when the AR display device is moving. The accelerometer can be arranged in the accommodating space.

The accelerometer is connected to the control unit 300, and outputs acceleration information obtained based on detection of the motion state of the AR display device to the control unit 300. For example, when the user uses the AR display device, the accelerometer may detect a motion state of the AR display device, and if the control component 300 determines that the acceleration is zero or approaches zero (or the acceleration value is small) according to the acceleration information output by the accelerometer, it indicates that the AR display device is in a stationary state or the AR display device is in a relatively stationary state (i.e., the user is in a stationary state or the user is in a relatively stationary state), for example, the user is in a non-stationary state. If the acceleration determined by the control component 300 according to the acceleration information output by the accelerometer is large, it indicates that the motion amplitude of the AR display device is large (the motion amplitude of the user is large); such as the user changing from a squatting state to a standing state, or the user walking, etc.

After receiving the acceleration information, the control part 300 determines a first output voltage according to the acceleration information, and transmits the first output voltage to the power supply part 500, so that the power supply part 500 supplies power to the electrochromic layer 120 according to the first output voltage to adjust the transmittance of the electrochromic layer 120. The acceleration information is an acceleration value.

In an embodiment of the present application, the control component 300 determines and adjusts the transmittance of the electrochromic layer 120 according to the acceleration information, which may be that the control component 300 determines the transmittance corresponding to the acceleration information according to the acceleration information, and further determines the first output voltage corresponding to the transmittance, and sends the first output voltage to the power supply component 500, so that the power supply component 500 supplies power to the electrochromic layer 120 according to the first output voltage, and the transmittance of the electrochromic layer 120 is adjusted to be the transmittance corresponding to the first output voltage, that is, the transmittance of the electrochromic layer 120 is adjusted by adjusting the voltage output to the electrochromic layer 120 by the power supply component 500.

The control unit 300 may pre-store a correspondence relationship among the acceleration information, the transmittance, and the voltage, so that the control unit 300 may determine the transmittance corresponding to the acceleration information according to the acceleration information, and then finally determine the voltage corresponding to the acceleration information according to the correspondence relationship between the transmittance and the voltage, where the voltage is the first output voltage.

In some embodiments of the present application, the acceleration is a linear acceleration, and the correspondence relationship between the linear acceleration a and the transmittance T and the voltage V may be as shown in table 1 below:

linear acceleration A (m/s)	Transmittance T	Voltage V (v)
			0≤A<0.5	4％	3.8
0.5≤A<1	8％	3.6
			1≤A<3	30％	2.5
3≤A<5	50％	1.5
			5≤A	80％	0

TABLE 1

For example, when the linear acceleration value output from the accelerometer to the control unit 300 is 2m/s, the control unit 300 may determine that the transmittance corresponding to the linear acceleration value is 30% based on the correspondence relationship between the acceleration value and the transmittance T and the voltage V in table 1 stored in advance in the control unit 300, and determine that the voltage value corresponding to the transmittance 30% is 2.5V, the control unit 300 determines that the output voltage corresponding to the linear acceleration value 2m/s output from the accelerometer is 2.5V, the control unit 300 transmits information including the output voltage of 2.5V to the power supply unit 500, and the power supply unit 500 supplies power to the electrochromic layer 120 at 2.5V based on the output voltage, and the transmittance of the electrochromic layer 120 is adjusted to 30% based on the output voltage 2.5V. That is, the control part 300 controls the voltage outputted from the power supply part 500 to the electrochromic layer 120 to be 2.5V, whereby it is possible to achieve the adjustment of the transmittance of the electrochromic layer 120 to 30%.

In another embodiment of the present application, the control component 300 determines and adjusts the transmittance of the electrochromic layer according to the acceleration information, and the control component 300 may determine a voltage value corresponding to the motion parameter according to the acceleration information, and send the voltage value to the power supply component 500 as a first output voltage, and the power supply component 500 supplies power to the electrochromic layer 120 according to the first output voltage, so that the transmittance of the electrochromic layer 120 is adjusted to the transmittance corresponding to the first output voltage, that is, the transmittance of the electrochromic layer is adjusted by adjusting the voltage output to the electrochromic layer by the power supply component 500. In this case, the correspondence relationship between the acceleration information and the voltage may be directly stored in the control unit, and the voltage corresponding to the acceleration information may be directly determined from the acceleration information.

In some embodiments of the present application, the acceleration is a linear acceleration, and the correspondence relationship between the linear acceleration a and the voltage V may be as shown in table 2 below:

linear acceleration A (m/s)	Voltage V (v)
		0≤A<0.5	3.8
0.5≤A<1	3.6
		1≤A<3	2.5
3≤A<5	1.5
		5≤A	0

TABLE 2

For example, when the linear acceleration value output from the accelerometer to the control unit 300 is 2m/s, the control unit 300 can determine that the voltage value corresponding to the linear acceleration value is 2.5V based on the correspondence relationship between the linear acceleration value and the voltage V and the linear acceleration a in table 2 stored in advance in the control unit 300, the control unit 300 transmits information including the output voltage of 2.5V to the power supply unit 500, and the power supply unit 500 supplies power to the electrochromic layer 120 at 2.5V based on the output voltage, so that the transmittance of the electrochromic layer 120 is adjusted to 30% based on the output voltage 2.5V. That is, the controlling part 300 controls the voltage outputted from the power supplying part 500 to the electrochromic layer 120 to be 2.5V by the controlling part 300, whereby it is possible to achieve the adjustment of the transmittance of the electrochromic layer 120 to a target value, which may be 30% corresponding to the voltage value of 2.5V.

It should be noted that, in an embodiment of the present application, a process of adjusting the voltage output from the power supply part 500 to the electrochromic layer 120 by the control part 300 to adjust the transmittance of the electrochromic layer 120 is described as follows. The power supply part 500 includes a power supply and a voltage control chip, the voltage control chip is respectively connected with the control part 300 and the power supply, the power supply is connected with the electrochromic layer 120, the control part 300 sends a voltage control command including a first output voltage to the voltage control chip according to the determined first output voltage, so that the voltage control chip controls the first output voltage of the power supply, that is, controls the voltage output from the power supply to the electrochromic layer 120 to be the first output voltage, thereby adjusting the transmittance of the electrochromic layer 120.

Illustratively, in an embodiment of the present application, the determining and adjusting the transmittance of the electrochromic layer according to the acceleration information by the control component 300 includes: the control part 300 determines whether the acceleration is greater than a preset acceleration threshold, and if so, the control part 300 determines that the first output voltage is a preset output voltage according to the motion parameter, and transmits the preset output voltage to the power supply part 500, that is, the transmittance of the electrochromic layer 120 is adjusted to be a preset transmittance; if not, the control part 300 does not need to perform the operation of determining the first output voltage according to the motion parameter and transmitting the first output voltage to the power supply part 500, i.e., the adjustment of the transmittance is not performed.

In order to ensure that the transmittance of the AR display device can meet the requirement of the user for seeing the real world environment clearly, the transmittance of the AR display device generally needs to be adjusted to a preset transmittance value, the preset transmittance value can be set by the control component 300 as required, and the value range of the preset transmittance value can be 5% to 30, which can be 5% or 8%, and which can also be set to other values above 8%, such as 10%, 15%, 30%, etc., as required.

For example, in general, for the AR display device, a transmittance may be preset by the control component 300, and the transmittance may be 8%, and for the electrochromic layer 120, after a lot of experiments are performed on the transmittance of the electrochromic layer 120, it is known that when the transmittance of the electrochromic layer 120 is 8%, the user can see the real world more clearly, so that it can be ensured that even when the user is in a motion state, when the transmittance of the electrochromic layer 120 is adjusted to the preset transmittance of 8%, the user can see the real world more clearly through the display lens 100. When the user is in motion, the transmittance of the electrochromic layer 120 is ensured to be more than 8%, so that the user can see the real world more clearly through the display lens 100. Conversely, in the static state, in order to enhance the viewing experience of the user for the display screen presented through the display lens body 110, the transmittance of the electrochromic layer 120 may be lower than 8% or even 0. When the user shifts from a stationary state such as sitting or lying to a moving state such as walking or running, the control part 300 actively adjusts the transmittance of the electrochromic layer 120 to 8% upon judging that the user currently enters the moving state based on the function of the control part 300.

An acceleration threshold corresponding to the preset transmittance may be preset in the control part 300, and when the control part 300 determines that the acceleration detected by the motion detection part 400 is greater than the acceleration threshold, the control part 300 controls the voltage output from the power supply part 500 to the electrochromic layer 120 to adjust the transmittance of the electrochromic layer 120. A voltage value corresponding to the preset transmittance value may be preset by the control part 300 as shown in the aforementioned table 1 or table 2, so that the control part 300 controls the voltage output from the power supply part 500 to the electrochromic layer 120 to be the preset voltage value.

The acceleration threshold may be set as desired, for example it may be 1m/s, 2m/s, etc. The setting of the acceleration threshold value can take the misjudgment factor of the motion state into consideration, and when the value of the threshold value is smaller, the detection of the motion state is more sensitive; otherwise, the process is slower.

That is, the motion parameter threshold is preset in the control component 300 and is used as a reference for the control component 300 to determine whether to adjust the transmittance, and the control component 300 compares the motion parameter detected by the motion detection component 400 with the motion parameter threshold to determine whether to adjust the transmittance of the electrochromic layer 120.

It should be noted that the acceleration information of the AR display device measured by the accelerometer may include the acceleration of the AR display device moving in the gravity direction and the gravity acceleration of the AR display device moving in the direction perpendicular to the gravity direction, that is, when the AR display device is used by a user, it may be detected that the user is stationary or non-stationary, and the non-stationary may be walking or moving change from standing to squatting or from squatting to standing, and the like.

Further, in another embodiment of the present application, the accelerometer may be a linear line accelerometer, such as a gravity accelerometer.

In an embodiment of the application, acceleration information of the movement of the AR display device is detected through an accelerometer, it can be detected that the AR display device is in a static state or a non-static state, when the AR display device is in the non-static state, the transmittance of the electrochromic layer 120 is adjusted to a proper transmittance threshold, so that a user can see the environment of the real world more clearly, and when the user moves, the user can determine a moving route conveniently, so that the experience of the user is improved.

For example, in another embodiment of the present application, when the control component 300 determines and adjusts the transmittance of the electrochromic layer 120 according to the acceleration, and when the control component 300 determines that the acceleration is greater than the preset acceleration threshold, the method further includes: judging whether the current transmittance of the electrochromic layer 120 is greater than a preset transmittance, if so, not adjusting the transmittance; if not, the transmittance of the electrochromic layer 120 is adjusted to a predetermined transmittance.

If the current transmittance of the electrochromic layer 120 is greater than the preset transmittance, then the user can see the real world environment through the display lens 100, and therefore, the control component 300 may keep the current transmittance unchanged without adjusting the transmittance of the electrochromic layer 120, that is, the control component 300 does not need to perform the operation of determining the first output voltage according to the motion parameter and transmitting the first output voltage to the power supply component 500. When the current transmittance of the electrochromic layer 120 is less than or equal to the preset transmittance, the control component 300 adjusts the transmittance, that is, the control component 300 determines the first output voltage as the preset output voltage according to the motion parameter, and sends the preset output voltage to the power supply component 500. Therefore, the problem that the transmittance of the electrochromic layer 120 is frequently adjusted, that is, the transmittance of the display lens 100 is frequently adjusted to affect the user experience can be avoided.

For example, in a static state, if the transmittance of the AR display device currently being used is 10%, the control unit 300 determines that it is higher than the preset transmittance of 8%, and at this time, the user can clearly see the real world through the display lens 100, and the transmittance adjustment may not be performed. When the user shifts from a stationary state such as sitting or lying to a motion state such as walking or running, the motion detecting part 400 detects acceleration information of the user and transmits the acceleration information to the control part 300. The control part 300 determines that the user enters a motion state according to the acceleration information, further determines whether the current transmittance of the electrochromic layer 120 is lower than a preset 8%, and if the current transmittance is higher than 8%, the current transmittance is maintained. Otherwise, the control part 300 actively adjusts the transmittance of the electrochromic layer 120 to 8%. For example, if the current transmittance of the electrochromic layer 120 is 30%, the transmittance is maintained at 30%; if the current transmittance of the electrochromic layer 120 is 4%, the control part 300 adjusts the transmittance of the electrochromic layer 120 to 8%.

It should be noted that, if the transmittance currently used by the AR display device is 10%, the control unit 300 determines that the transmittance is higher than the preset transmittance of 8%, and at this time, the transmittance may be adjusted to be 8%. Further, if the transmittance currently used by the AR display device is 10%, the control unit 300 determines that the transmittance is higher than the preset transmittance by 8%, at this time, the transmittance may be adjusted to a higher transmittance, such as 30%, 50%, etc., so that the user can more clearly view the external real world. For the adjustment of the transmittance, it may preset a specific adjustment policy in the control part 300 as needed to cause the AR display device to adjust the transmittance of the electrochromic layer 120 according to the adjustment policy.

That is, when the current transmittance of the electrochromic layer 120 is greater than the preset transmittance, even if the motion parameter detected by the motion detection component 400 is greater than the motion parameter threshold, the control component 300 does not adjust the transmittance, and only when the current transmittance of the electrochromic layer 120 is less than or equal to the preset transmittance and the motion parameter is greater than the motion parameter threshold, the transmittance is adjusted, so that the transmittance of the electrochromic layer 120 can be prevented from being frequently adjusted, and the user experience can be further improved.

Further, the AR display device provided in the present embodiment further includes setting an initial transmittance of the electrochromic layer 120. The control part 300 automatically sets the transmittance of the electrochromic layer 120 to the initial transmittance each time the AR display device is rebooted.

For example, referring to fig. 3, in another embodiment of the present application, the AR display device further includes a transmittance manual adjustment component 600, where the transmittance manual adjustment component 600 is provided with a plurality of transmittance gears corresponding to different transmittances; the transmittance manual adjustment part 600 is connected to the control part 300, and the control part 300 determines a second output voltage according to a transmittance gear selected by a user through the transmittance manual adjustment part 600 to adjust the transmittance of the electrochromic layer 200.

When the user starts using the AR display device, the user may set the transmittance of the AR display device according to the transmittance manual adjustment part 600 to set an initial transmittance (i.e., set the initial transmittance of the electrochromic layer 120). Then, in the using process, the AR display device detects the motion state of the AR display device through the motion detection part 400, and the control part 300 may perform the aforementioned adjustment on the initial transmittance of the electrochromic layer 120 through the motion parameters output by the motion detection part 400.

Further, after the control unit 300 adjusts the initial transmittance according to the motion parameter of the user detected by the motion detection unit 400, the user may manually adjust the adjusted transmittance again by the transmittance manual adjustment unit 600. Namely, the automatic adjustment and the manual adjustment of the transmittance can be satisfied to improve the experience of the user.

Of course, the manual transmittance adjustment component 600 may also set one or more transmittance levels for the user to adjust the transmittance.

In addition, with the foregoing solution, when the motion detection component 400 detects that the motion parameter value is large (i.e. when the user is in a relatively strenuous exercise), the control component 300 may directly adjust the transmittance of the electrochromic layer 120 to the preset transmittance, so as to meet the user's requirement.

It should be noted that the control component 300 is connected to the transmittance manual adjustment component 600, receives transmittance gear information fed back to the control component 300 by the transmittance manual adjustment component 600, determines a second output voltage according to the gear information, and sends the second output voltage to the control component 300, so as to control the voltage output to the electrochromic layer 120 by the power supply component 500, and adjust the transmittance of the electrochromic layer 120.

The transmittance manual adjustment component 600 may be provided in a button shape, and only 1, a plurality of gears may be sequentially traversed by pressing the button, for example, 5 gears may be provided, where the 5 gears may be a gear with 4% transmittance, 8% transmittance, 30% transmittance, 50% transmittance and 80% transmittance, the first button is adjusted to a 4% transmittance, the second button is adjusted to a 8% transmittance, the third button is adjusted to a 30% transmittance, the fourth button is adjusted to a 50% transmittance, the fifth button is adjusted to a 80% transmittance, and if the button is pressed again, the adjustment to a 4% transmittance is presented, and the aforementioned adjustments are sequentially repeated.

In another embodiment of the present application, a corresponding number of shift buttons may also be set according to the number of the shift positions, and each button corresponds to one shift position.

In another embodiment of the present application, the transmittance manual adjustment component 600 may also be provided in the form of a slide bar, and a plurality of fixed positions corresponding to transmittance gears are provided on the sliding path, and the transmittance corresponding to the positions is determined by the fixed positions after sliding.

In the present application, the number, shape, and the like of the transmittance manual adjustment member 600 may be provided as needed.

Due to the arrangement of the transmittance manual adjustment component 600, the transmittance can be directly adjusted by the user through the transmittance manual adjustment component 600, so that the transmittance can be adjusted by the user according to personal use requirements, and the experience of the user can be improved.

The accelerometer detects acceleration information during the movement of the user, and outputs the acceleration information to the control unit 300, where the acceleration information may be the linear acceleration described above, or may be other information indicating the magnitude of the linear acceleration, such as a voltage value or a current value indicating the magnitude of the linear acceleration.

In another embodiment of the present application, a plurality of transmittance gears may be further set according to the motion state of the AR display device, and a corresponding relationship between the motion parameter range and the output voltage may be preset, for example, the motion parameter is the aforementioned linear acceleration, and the corresponding relationship between the linear acceleration a and the transmittance T and the voltage V may be as shown in table 3 below:

TABLE 3

When the control part 300 receives the acceleration detected by the accelerometer, it determines the acceleration range to which the linear acceleration belongs, for example, the linear acceleration is 0.8m/s, then the control part 300 may determine that the transmittance of the electrochromic layer 120 needs to be adjusted to 8% corresponding to the linear acceleration of 0.8m/s according to the corresponding relationship between the linear acceleration a, the transmittance T and the voltage V in table 3 pre-stored in the control part 300 and the linear acceleration value, and then the control part 300 sends the determined output voltage to the power supply part 500 to be 3.6V; if the linear acceleration is 1m/s, the control part 300 needs to adjust the transmittance of the electrochromic layer 120 to 30%, and the control part 300 transmits a certain output voltage of 2.5V to the power supply part.

It should be noted that, generally, the transmittance is in a positive correlation with the acceleration, that is, the greater the acceleration is, the greater the intensity of the user's motion is, the transmittance should be adjusted to be higher, so that the user can see the environment of the real world more clearly, the safety of the user is improved, and the experience of the user is improved.

The correspondence relationship between the acceleration range and the transmittance may be set as needed, and is not limited in the embodiments of the present application.

That is, the control component 300 presets the corresponding relationship between the motion parameters and the output voltages, so that a plurality of different output voltage gears can be set, different output voltage gears correspond to different transmittance gears, and the control component 300 matches the motion parameters detected by the motion detection component 400 with the corresponding relationship to determine the output voltages corresponding to the motion parameters, thereby realizing multi-gear adjustment to meet the requirements of users on transmittance in different motion states. For example, the transmittance of the electrochromic layer 120 may be low when the user is in a static state, the transmittance of the electrochromic layer 120 may be slightly high when the user is in a slow-walking state, the transmittance of the electrochromic layer 120 may be higher when the user is in a fast-walking state, and the like. This can improve the user experience.

In another embodiment of the present application, the motion detection component 400 may include an accelerometer and a gyroscope, for example, the motion detection component 400 may be an IMU (Inertial measurement unit), such as a common IMU that includes three-axis accelerometers and three-axis gyroscopes. Compared with the accelerometer, the IMU can detect the motion state of the AR display device more accurately, for example, the IMU can further detect the angular acceleration information of the motion, so that the motion state of the AR display device can be known more accurately.

Further, the IMU may output linear acceleration information and angular acceleration information. The correspondence relationship between the acceleration information for identifying the user state output by the IMU, the transmittance, and the voltage may be set as needed, and is not limited in the embodiments of the present application.

For example, the correspondence relationship between the linear acceleration a and the angular acceleration B output by the IMU, the transmittance T, and the voltage V may be as shown in table 4 below:

linear acceleration A (m/s)	Angular acceleration B (rad/S)²)	Transmittance T	Voltage V (v)
				0≤A<0.5	0≤B<0.5	4％	3.8
0.5≤A<1	0.5≤B<1	8％	3.6
				1≤A<3	1≤B<3	30％	2.5
3≤A<5	3≤B<5	50％	1.5
				5≤A	5≤B	80％	0

TABLE 4

For example, the IMU outputs to the control unit 300 a linear acceleration value of 2m/S and an angular acceleration value of 2rad/S²The control part 300 determines the linear acceleration value and the angular acceleration value according to the corresponding relation between the linear acceleration value and the angular acceleration value and the linear acceleration A, the angular acceleration B, the transmittance T and the voltage V in the table 4 pre-stored in the control part 300The transmittance corresponding to the value and the angular acceleration value is 30%, and it is determined that the voltage value corresponding to the transmittance of 30% is 2.5V, the control part 300 controls the voltage outputted from the power supply part 500 to the electrochromic layer 120 to be 2.5V, whereby it is possible to achieve the adjustment of the transmittance of the electrochromic layer 120 to 30%.

It should be noted that the motion parameter in the present application may be the aforementioned acceleration information, and may also be a displacement amount of the AR display device (user). The amount of displacement may be an amount of displacement of movement of the AR display device (user) in a direction perpendicular to gravity. And the motion detection part 400 may include a global positioning module for detecting the aforementioned displacement amount.

The Global Positioning module may be a GPS (Global Positioning System), and the GPS may detect a displacement amount of the AR display device (user) occurring within a certain period of time.

The movement state of the AR display device (user) is detected through the GPS, whether the AR display device (user) displaces relative to the initial position or the position in the previous time period or not can be detected, if obvious displacement amount (large displacement amount) is detected, the AR display device (user) is considered to be in a non-static state, and if no displacement occurs or the displacement amount is small, the AR display device (user) is considered to be in a relative static state, namely, the AR display device (user) does not move in the direction vertical to the gravity direction.

Illustratively, a threshold value of the amount of displacement may be set in advance by the control part 300, and then the control part 300 compares the amount of displacement detected by the motion detection part 400 with the threshold value of the amount of displacement, and if the amount of displacement detected by the motion detection part 400 is equal to or greater than the threshold value of the amount of displacement, the control part 300 adjusts the transmittance of the electrochromic layer 120 to a preset transmittance; the control part 300 does not perform the adjustment of the transmittance if the displacement amount detected by the motion detection part 400 is smaller than the displacement amount threshold.

Further, if the displacement detected by the motion detection component 400 is greater than or equal to the displacement threshold, the control component 300 needs to determine whether the current transmittance of the electrochromic layer 120 is greater than the preset transmittance, and if so, the control component 300 does not adjust the transmittance.

Further, in another embodiment of the present application, the control component 300 may further set a plurality of corresponding relationships between the displacement S and the transmittance T and the voltage V, for example, as shown in the following table 5:

TABLE 5

For example, when the displacement amount output from the GPS to the control unit 300 is 1.2m, the control unit 300 determines that the transmittance corresponding to the displacement amount is 50% based on the displacement amount and the correspondence relationship between the displacement amount S and the transmittance T and the voltage V in table 5 stored in advance in the control unit 300, and the voltage value corresponding to the transmittance is 1.5V, and the control unit 300 controls the voltage output from the power supply unit 500 to the electrochromic layer 120 to be 1.5V, whereby the transmittance of the electrochromic layer 120 can be adjusted to 50%.

When the control part 300 receives the displacement amount of the AR display device (user) fed back by the GPS, it determines the displacement amount range to which the displacement amount belongs, for example, the displacement amount is 0.4m/s, and the control part 300 adjusts the transmittance of the electrochromic layer 120 to 8% by controlling the voltage output to the electrochromic layer 120 by the power supply part 500, and adjusts the transmittance of the electrochromic layer 120 to 50% if the displacement amount is 1.2 m/s.

It should be noted that, in general, the transmittance is in a positive correlation with the displacement, that is, the greater the displacement, the greater the intensity of the motion of the AR display device (user), the transmittance of the electrochromic layer 120 should be adjusted to be higher, so that the user can see the real world environment more clearly, and the safety of the user is improved, so as to improve the experience of the user.

The correspondence relationship between the displacement amount range and the transmittance may be set as needed, and is not limited in the embodiments of the present application.

It should be noted that, the displacement may be a sum of displacements within a preset time period, or a distance difference between an initial position and a final position within a certain time period, and may be set as needed, which is not limited in the embodiment of the present application.

The preset time can also be set according to needs, for example, to 0.5s, 1s, 2s, and the like.

In other embodiments, the motion detection component 400 may also include a camera that may be mounted on the front of the AR display device, for example, on the side of the frame 210 away from the user's glasses as in fig. 2A. The camera may include any one of Mono camera, TOF camera, monocular camera, binocular camera, or multi-view camera. Specifically, the displacement amount and the motion state of the user can be detected by the camera. For example, a displacement of the user with respect to the initial position or a displacement occurring over a period of time may be detected by the camera. By detecting the translation and rotation transformation relationship between two coordinate systems, 3 positions and 3 rotation angles are included. The AR display device may refer to the above embodiments for the step of adjusting the light transmittance according to the displacement.

In other embodiments, the motion detection component 400 may also include radar for location determination. The radar may be mounted in front of the AR display device. Specifically, the displacement amount and the motion state of the user can be detected by radar. For example, a displacement of the user with respect to an initial position or a displacement occurring over a period of time may be detected by a radar. The target is found and the position of the target is determined by utilizing the reflection or scattering of the target to the electromagnetic wave, so that the detection, the positioning, the tracking, the imaging and the identification of the target are realized. The AR display device may refer to the above embodiments for the step of adjusting the light transmittance according to the displacement.

It should be noted that the motion parameter in this application may be the aforementioned acceleration information or the displacement of the user, or may be other information that can be used to represent the motion state of the AR display device, and this may be set as needed, and is not limited in this embodiment of the application.

For example, referring to fig. 3, in another embodiment of the present application, the AR display apparatus further includes a light intensity detecting part 700, and the light intensity detecting part 700 is connected to the control part 300; wherein the light intensity detecting section 700 is used to detect light intensity information of the environment in which the AR display device is located; the control part 300 determines the first output voltage according to the motion parameter and the light intensity information to adjust the transmittance of the electrochromic layer 120.

The light intensity detecting member 700 may be a light sensor, which may be provided on the frame 210 described above, for example, may be provided on the frame 210 at a position above the bridge of the nose as shown in fig. 1.

The light intensity detecting member 700 may be provided at a position where the temple 220 is close to the frame 210, and may detect ambient light to obtain light intensity information.

For example, in an embodiment of the present application, the control part 300 determines the first output voltage according to the motion parameter detected by the motion detection part 400 and the light intensity information detected by the light intensity detection part 700 to adjust the transmittance of the electrochromic layer 120, and when the control part 300 determines that the motion parameter detected by the motion detection part is less than or equal to the preset motion parameter threshold, the control part 300 determines the first output voltage according to the light intensity information detected by the light intensity detection part 700 to adjust the transmittance of the electrochromic layer 120; when the control part 300 judges that the motion parameter is greater than the preset motion parameter threshold, the control part 300 determines a first output voltage according to the motion parameter detected by the motion detection part to adjust the transmittance of the electrochromic layer 120; the transmittance is inversely related to the light intensity.

When AR display device (user) is static state or has only taken place slight motion, control unit 300 can be according to the transmittance of ambient light intensity adjustment electrochromic layer 120, and can control unit 300 sets up a plurality of transmittance gears that correspond to ambient light intensity to satisfy the adjustment demand of transmittance under different ambient light AR display device (user) takes place the motion, and control unit 300 adjusts the transmittance of electrochromic layer 120 according to the motion parameter, can improve user's experience from this.

Further, when the control part 300 adjusts the transmittance of the electrochromic layer 120 according to the ambient light intensity, the set transmittance of the electrochromic layer 120 may be lower than the preset transmittance threshold.

The ambient light intensity may affect the contrast of the display image of the display lens body 110 and the definition of the display image, for improving the user experience, when the control component 300 adjusts the transmittance of the electrochromic layer 120 according to the motion state of the AR display device, the transmittance of the electrochromic layer 120 may also be adjusted by combining the ambient light intensity at the same time, for example, only when the motion parameter is less than or equal to the preset motion parameter threshold, the control component 300 determines the first output voltage according to the light intensity information, so as to adjust the transmittance of the electrochromic layer 120, thereby adjusting the display contrast of the display lens 100. When the motion parameter is greater than the preset motion parameter threshold, the control part 300 preferentially determines the first output voltage according to the motion parameter to adjust the transmittance of the electrochromic layer 120. That is, the motion state of the AR display device of the user is taken as a first consideration when the transmittance of the electrochromic layer 120 is adjusted, so that the use requirements of the user in different motion states can be met, and the user can clearly see the external environment when moving, for example.

TABLE 6

That is, it can be determined from the correspondence relationship between the acceleration a and the illuminance L and the transmittance T and the voltage V in the table 6 stored in advance in the control unit 300, and when the acceleration is less than 0.5m/s, the control unit 300 can determine the first output voltage according to the light intensity to adjust the transmittance of the electrochromic layer 120, and if the illuminance is 1500, the control unit 300 transmits the output voltage of 3.8V to the power supply unit 500 to adjust the transmittance of the electrochromic layer 120 to 4%, and if the illuminance is 1100, the control unit 300 transmits the output voltage of 3.7V to the power supply unit 500 to adjust the transmittance of the electrochromic layer 120 to 6%. When the acceleration is more than 0.5m/s, the control part 300 transmits an output voltage of 3.6V to the power supply part 500 to directly adjust the transmittance of the electrochromic layer 120 to 8% according to the acceleration.

In one embodiment of the present application, the light intensity detecting part 700 sends the detected light intensity information to the control part 300, and the control part 300 controls the voltage output from the power supply part 500 to the electrochromic layer 120 according to the light intensity information to adjust the transmittance of the electrochromic layer 120.
