2) The ambient light brightness is too low and is lower than a certain threshold value, the transmittance of the photochromic layer is adjusted to the highest value under the control of the control signal, and the transmittance is gradually reduced based on the intensity of the ambient light under the control of the control signal until the display content is clearly visible.
3) When the backlight brightness does not reach the set maximum value for some reason (e.g., overheating, aging, etc.), the maximum threshold for detecting the ambient light may be adjusted down.
Through adjusting the combination scheme of AR display module luminance and photochromism layer transmissivity, guaranteed the clear visibility of intelligent glasses demonstration content to adjustment scheme under the multiple condition has been considered.

In the present embodiment, the optical waveguide lens 202 is disposed on the outer side of the display unit (outer side, i.e., the end away from the eyeglasses), and the optical waveguide lens 202 transmits the image displayed by the display unit 201 to the image output area of the lens so that the wearer's eyes see the image through the area.

In this alternative implementation, the cover glass 204 may be located on the outermost side of the smart eyewear display unit, away from the wearer's eyes. The electrochromic layer may be attached to the inside of the cover glass. Through increasing one deck electrochromic layer in optical waveguide lens module, set up in the outside of lens (keeping away from people's eye), can reduce the transmissivity of external light to solve the not enough problem of high brightness scene intelligence glasses demonstration luminance. Compared with array type optical waveguide intelligent glasses in the related art, the array type optical waveguide intelligent glasses have the advantages that the electrochromic layer and the protective glass are added, and the transmittance of the environment view can be adjusted.

Diffractive light waveguide lenses include, but are not limited to, diffractive light waveguide smart glasses made by a nanoimprint grating process, diffractive light waveguide smart glasses made by a volume hologram process, and the like.
Compared with the scheme that the photochromic layer and the protective glass are separately added outside the AR glasses display unit in the first embodiment, the space is saved, and the weight is reduced by integrating the photochromic layer inside the protective glass.
Specifically, the electrochromic layer comprises a plurality of electrochromic units which are arranged on the whole surface, and the light transmittance of the electrochromic layer can be controlled through an electric signal.

In the present embodiment, a light sensing unit (not shown in the drawings) may be disposed anywhere in the smart glasses as needed, and the light sensing unit includes, but is not limited to, a light sensor, a photodiode, and the like, for detecting the brightness of the ambient light and generating a sensing signal.
The device also comprises a control unit which is connected with the light sensing unit to receive the sensing signal and generate a control electric signal based on the sensing signal; and is also connected to the electro-variable layer, which changes light transmittance under the control of the control signal.
In this embodiment, the control unit (not shown in the figure) may be disposed inside the smart glasses as required, connected to the light sensing unit, and configured to receive the sensing signal generated by the light sensing unit and generate the control signal based on the sensing signal.
Specifically, the control unit may be connected to the electrochromic layer 203, and the control signal may also control light transmittance of the electrochromic layer.

In this alternative implementation, the control unit may be electrically connected to the display unit 201, and the control signal may control the backlight brightness of the display unit 201.
The manner in which the control signal controls the backlight brightness, and the light transmittance, may be determined based on the brightness of the ambient light. Including but not limited to the following scenarios:
1) ambient light is too strong, preset threshold has been exceeded, under control signal's control, display element 101's backlight brightness value is increaseed to maximum brightness, but the wearer still can't see the content of screen clearly under the highlight, then under control signal's control, with the transmissivity of the electrochromic layer of intelligent glasses turn down, know the setting value, consequently, display element shows that the backlight brightness of content does not receive the influence that the photochromic layer transmissivity reduces, luminance remains unchanged, but after ambient light shines through the photochromic layer of AR glasses module, ambient light's luminance reduces, thereby the content that shows is clearly visible.
2) The ambient light brightness is too low and is lower than a certain threshold value, the transmittance of the photochromic layer is adjusted to the highest value under the control of the control signal, and the transmittance is gradually reduced based on the intensity of the ambient light under the control of the control signal until the display content is clearly visible.
3) When the backlight brightness does not reach the set maximum value for some reason (e.g., overheating, aging, etc.), the maximum threshold for detecting the ambient light may be adjusted down.
It will be appreciated that the maximum value of the backlight brightness, the minimum value of the backlight brightness, the maximum transmittance, the minimum transmittance of the electrochromic layer, the maximum threshold value, the minimum threshold value of the ambient light may all be modified as desired. The above application scenarios are only exemplary, and the schemes related to the matching adjustment of transmittance and backlight brightness are within the scope of the present disclosure.
In this embodiment, by changing the light transmittance and the backlight brightness of the display unit, it can be ensured that the smart glasses can ensure that the image display content is clearly visible under any ambient light, and compared with the existing array type optical waveguide AR glasses, one electrochromic layer and protective glass (as shown in fig. 2) are added. The problems that in the related art, the power consumption is large, the heat dissipation pressure is large and the definition of image display content cannot be guaranteed in the scheme of the backlight lamp are solved.
According to an embodiment of the present disclosure, there is also provided a smart glasses display method, and an exemplary structure applicable to the method may include: the display unit comprises an image display module and an optical lens module which are sequentially arranged from the inner side of the intelligent glasses to the outer side of the intelligent glasses and are used for displaying and inputting images of the intelligent glasses; the optical waveguide lens is arranged on the outer side of the optical lens module and is used for transmitting the image displayed by the display unit to a target area so as to observe the image through the target area; the electrochromic layer is arranged on the outer side of the optical waveguide lens and is used for changing the transmittance of ambient light; the light sensing unit comprises a light sensor and a light sensing unit, wherein the light sensor is used for detecting light brightness and generating a sensing signal; the control unit is connected with the light sensing unit to receive the sensing signal and generate a control electric signal based on the sensing signal; and an electro-variable layer that changes light transmittance under control of the control signal. Wherein, a protective glass is arranged outside the electrochromic layer. The electrochromic layer is integrally arranged on the inner side of the protected glass. As shown in fig. 3, the method includes:
step 301: and receiving an ambient light sensing signal detected by the light sensor.
In this embodiment, the sensing signal of the brightness of the ambient light detected by the light sensor may be received first.
Step 302: and judging whether the brightness of the ambient light is higher than a first target threshold value or not based on the ambient light sensing signal, and if so, generating a first control signal to adjust the display brightness of the display unit to the maximum value and adjust the light transmittance of the electrochromic layer until the light transmittance is adjusted to the minimum value.
In this embodiment, referring to fig. 4, fig. 4 shows a schematic diagram of a transmittance and a display brightness adjustment curve of a photochromic layer of smart glasses, when the ambient light brightness exceeds a certain threshold, at this time, the brightness of a display unit of AR glasses is increased to a set maximum brightness Lmax (not greater than the maximum brightness of a display unit (inherent) of the AR glasses), the glasses of a wearer cannot see the display content clearly, and a control unit of the AR glasses starts to gradually decrease the transmittance of the electrochromic layer of the AR glasses module until a set minimum transmittance Tmin (not less than the minimum transmittance of the photochromic layer) is reached. At this time, because the brightness of the AR display content is not affected by the reduction of the transmittance of the photochromic layer, the brightness remains unchanged, but after the ambient light rays transmit the photochromic layer of the AR eyeglass module, the brightness is reduced, and the AR content display is clear and visible.
As an optional implementation manner of this embodiment, based on the ambient light sensing signal, it is determined whether the brightness of the ambient light is lower than a second target threshold, and if the brightness of the ambient light is lower than the second target threshold, a second control signal is generated to adjust the display brightness of the display unit to a minimum value and adjust the light transmittance of the electro-variable layer until the light transmittance is adjusted to a maximum value.
In this optional implementation manner, referring to fig. 4, when the ambient light brightness is lower than a certain threshold, the ambient light is not strong, the transmittance of the photochromic layer of the AR glasses is adjusted to a maximum value Tmax (less than or equal to the maximum transmittance of the photochromic layer), and the brightness of the display unit of the AR glasses can be gradually reduced according to the ambient light until the minimum brightness Lmin, so as to satisfy the requirement of clear display without dazzling.
As an optional implementation manner of this embodiment, the method further includes changing the target threshold when the display brightness of the display unit cannot be adjusted to the maximum value.
In this alternative implementation, if the display unit of the current AR glasses does not reach the set maximum brightness Lmax for some reason (e.g., overheating, aging, etc.), the threshold of the ambient light may be adjusted down appropriately.
Specifically, the parameter such as the ambient light brightness threshold, which may be a specific value, may also be a range, that is: when the ambient light brightness is from high to low, two values are corresponding to the ambient light brightness from low to high, so that the corresponding brightness adjustment and the photochromic layer transmittance adjustment are more complicated than the current two-section adjustment, and a better setting effect is achieved. Similar adjustment strategy is within the scope of the present application.
It will be appreciated that the AR glasses may adjust the above-mentioned parameters of maximum display luminance Lmax, minimum display luminance Lmin, maximum transmittance Tmax, minimum transmittance Tmin, threshold value of ambient light brightness ALthreshold, etc. to match the needs of different users.
As an optional implementation manner of this embodiment, the adjusting the light transmittance of the electro-variable layer includes adjusting the light transmittance through a voltage adjusting manner, a duty ratio PWM adjusting manner, and a current magnitude adjusting manner.
In this optional implementation manner, the transmittance adjustment scheme of the electrochromic layer is different from the implementation scheme in terms of material, and includes but is not limited to voltage adjustment (voltage level, electrode direction, energization time, and the like), duty ratio PWM adjustment, current magnitude adjustment, and the like.
It is understood that the display brightness adjustment of the AR glasses and the transmittance adjustment of the photochromic layer may be linear or non-linear adjustment schemes, and are within the scope of the present patent.
