第三方面,提供一种电子设备的调节方法,包括:光纤扫描显示器出射第一激光光束,第一激光光束投射的第一显示画面为自由曲面;透镜组接收并反射有效激光光束,并以第二激光光束出射,第二激光光束投射的第二显示画面为平面;光波导接收第二激光光束,经调节以第三激光光束出射,第三激光光束投射的第三显示画面为平面。In the third aspect, a method for adjusting an electronic device is provided, including: the optical fiber scanning display emits a first laser beam, and the first display picture projected by the first laser beam is a free-form surface; the lens group receives and reflects an effective laser beam, and uses the first laser beam The second laser beam is emitted, and the second display screen projected by the second laser beam is flat; the optical waveguide receives the second laser beam, and is adjusted to emit the third laser beam, and the third display screen projected by the third laser beam is flat.

本申请实施例提供的电子设备及电子设备的调节方法中,电子设备包括光纤扫描显示器、透镜组、以及光波导。从光纤扫描显示器出射的有效激光光束投射的第一显示画面为自由曲面,可以在光纤扫描显示器的出光侧设置透镜组,透镜组可以对第一激光光束的光路进行校正,使从透镜组出射的第二激光光束投射的第二显示画面为平面,进而第二激光光束经过光波导进行反射或衍射后,出射的第三激光光束投射的第三显示画面仍为平面。由于用户在观看电子设备整体的显示画面时,看到的是呈平面面型的第三显示画面,而非呈自由曲面的第一显示画面,因此,可以改善用户观看电子设备的显示画面时,出现视觉失真的问题。在此基础上,由于从光纤扫描显示器出射的第一激光光束的方向性好、发散角度较小,因此,更便于利用透镜组对第一激光光束进行调节。In the electronic device and the method for adjusting the electronic device provided in the embodiments of the present application, the electronic device includes an optical fiber scanning display, a lens group, and an optical waveguide. The first display picture projected by the effective laser beam emitted from the fiber-optic scanning display is a free-form surface, and a lens group can be arranged on the light-emitting side of the fiber-optic scanning display.

Since the user sees the third display screen in the form of a plane surface instead of the first display screen in the form of a free curved surface when viewing the overall display screen of the electronic device, it can improve the user's viewing of the display screen of the electronic device. There is a problem with visual distortion. On this basis, since the first laser beam emitted from the optical fiber scanning display has good directivity and a small divergence angle, it is more convenient to use the lens group to adjust the first laser beam.

Among them, the cause of visual distortion is: when the fiber cantilever of the fiber optic scanning display scans, its scanned trajectory is a free-form surface, and the shape of the picture formed by the light rays emitted from the fiber-optic scanning display is the free-form surface shown in FIG. 1 .

为解决背景技术提出的技术问题,发明人经研究提出了以下方案,以改善用户在观看光纤扫描显示器显示的画面时,出现视觉失真的问题。In order to solve the technical problems raised by the background technology, the inventor proposes the following solutions after research, so as to improve the problem of visual distortion when the user watches the picture displayed by the optical fiber scanning display.

如图2所示,本申请实施例提供一种电子设备10,包括:光纤扫描显示器11,透镜组12以及光波导13。请同时参阅图3,光纤扫描显示器11用于出射第一激光光束111,第一激光光束投射的第一显示画面的形状为自由曲面。如图4a所示,第一激光光束进入透镜组12,并以第二激光光束121出射,第二激光光束121投射的第二显示画面为平面(图4b)。第二激光光束进入光波导13,经调节以第三激光光束131出射,第三激光光束131投射的第三显示画面为平面。As shown in FIG. 2 , an embodiment of the present application provides an electronic device 10 , including: a fiber optic scanning display 11 , a lens group 12 and an optical waveguide 13 . Please also refer to FIG. 3 , the optical fiber scanning display 11 is used to emit a first laser beam 111 , and the shape of the first display screen projected by the first laser beam is a free-form surface. As shown in FIG. 4 a , the first laser beam enters the lens group 12 and exits as the second laser beam 121 , and the second display image projected by the second laser beam 121 is a plane ( FIG. 4 b ). The second laser beam enters the optical waveguide 13 and is adjusted to emit the third laser beam 131 . The third display image projected by the third laser beam 131 is a plane.

在一些实施例中,从光纤扫描显示器11出射的第一激光光束投射的第一显示画面,从透镜组12出射的第二激光光束121投射的第二显示画面,从光波导13投射的第三激光光束131构成的第三显示画面中,用户实际看到的画面为第三显示画面。In some embodiments, the first display frame projected by the first laser beam emitted from the optical fiber scanning display 11, the second display frame projected by the second laser beam 121 emitted from the lens group 12, and the third display frame projected from the optical waveguide 13 Among the third display screens formed by the laser beam 131 , the screen that the user actually sees is the third display screen.

在一些实施例中,第一激光光束111可以全部入射至透镜组12;或者,第一激光光束111中的一部分入射至透镜组12。In some embodiments, all of the first laser beam 111 may be incident on the lens group 12 ; or, a part of the first laser beam 111 may be incident on the lens group 12 .

在一些实施例中,不对透镜组12的具体组成以及各个组成部分的具体参数进行限定,只要进入透镜组12的第一激光光束111从透镜组12以第二激光光束121出射后,第二激光光束121投射的第二显示画面为平面即可。In some embodiments, the specific composition of the lens group 12 and the specific parameters of each component are not limited, as long as the first laser beam 111 entering the lens group 12 exits the lens group 12 as the second laser beam 121, the second laser beam The second display image projected by the light beam 121 only needs to be a plane.

其中,可以采集从光纤扫描显示器11出射的第一激光光束在各个像素点的光路,根据第一激光光束构成的自由曲面面型、平面面型的成像面、以及第二激光光束121的出射方向之间的几何位置关系,利用光学软件进行拟合,可以得到透镜组12的具体组成以及各个组成部分的具体参数。第一激光光束111进入透镜组12后,可以根据透镜组12的具体组成,在透镜组12中经过至少一次成像。Wherein, the optical path of the first laser beam emitted from the optical fiber scanning display 11 at each pixel point can be collected, according to the free-form surface type, the imaging surface of the planar surface type formed by the first laser beam, and the emission direction of the second laser beam 121 The geometric positional relationship among them is fitted by using optical software, and the specific composition of the lens group 12 and the specific parameters of each component can be obtained. After the first laser beam 111 enters the lens group 12 , it may be imaged in the lens group 12 at least once according to the specific composition of the lens group 12 .

可选的,参考图5,沿远离透镜组12的光接收面的方向,透镜组12包括依次设置的第一汇聚透镜组、发散透镜组、以及第二汇聚透镜组。第一汇聚透镜组用于汇聚有效激光光束,发散透镜组用于发散有效激光光束,第二汇聚透镜组用于汇聚第一激光光束、并使得第二激光光束进入光波导13。Optionally, referring to FIG. 5 , along the direction away from the light receiving surface of the lens group 12 , the lens group 12 includes a first converging lens group, a diverging lens group, and a second converging lens group arranged in sequence. The first converging lens group is used for converging the effective laser beam, the diverging lens group is used for diverging the effective laser beam, and the second converging lens group is used for converging the first laser beam and making the second laser beam enter the optical waveguide 13 .

第一激光光束经过第一汇聚透镜组汇聚后,可以成缩小的像,以沿透镜组12的光接收面到光出射面的垂直方向,使构成缩小的像中各个第一激光光束之间的距离减小,相较于第一显示画面,此时的缩小的像的形状更接近于平面;之后,第一激光光束经过发散透镜组成放大的像,且经过发散透镜组所成的放大的像,小于第一激光光束经过第一汇聚透镜组后所成的像,通过将第一激光光束放大,可以满足用户的观看需求,避免用户看到的画面过小;最后,再经过第二汇聚透镜组,再次对第一激光光束进行汇聚,以沿透镜组12的光接收面到光出射面的垂直方向,使构成缩小的像中各个第一激光光束之间的距离趋近于零,即可得到形状为平面的第二显示画面,并且,使得从透镜组12出射的第二激光光束尽可能多地入射到光波导13中。After the first laser beam is converged by the first converging lens group, it can become a reduced image, so that the distance between each first laser beam in the reduced image can be formed along the vertical direction from the light-receiving surface of the lens group 12 to the light-emitting surface. The distance decreases. Compared with the first display screen, the shape of the reduced image at this time is closer to the plane; after that, the first laser beam passes through the diverging lens to form an enlarged image, and the enlarged image formed by the diverging lens group , which is smaller than the image formed by the first laser beam passing through the first converging lens group, by enlarging the first laser beam, it can meet the user's viewing needs and prevent the user from seeing too small a picture; finally, the second converging lens group, the first laser beams are converged again, so that the distance between the first laser beams in the reduced image approaches zero along the vertical direction from the light-receiving surface to the light-emitting surface of the lens group 12, that is, A second display image in the shape of a plane is obtained, and the second laser beam emitted from the lens group 12 is made to enter the optical waveguide 13 as much as possible.

不对第一汇聚透镜组、发散透镜组、以及第二汇聚透镜组的具体组成进行限定。The specific composition of the first converging lens group, the diverging lens group, and the second converging lens group is not limited.

示例的,如图5所示,沿远离透镜组12的光接收面的方向,透镜组12包括依次设置的第一汇聚透镜122、第二汇聚透镜123、发散透镜124、第三汇聚透镜125及第四汇聚透镜126;第一汇聚透镜122、第二汇聚透镜123、第三汇聚透镜125、以及第四汇聚透镜126用于汇聚有效激光光束,发散透镜用于发散有效激光光束。Exemplary, as shown in Figure 5, along the direction away from the light-receiving surface of the lens group 12, the lens group 12 includes a first converging lens 122, a second converging lens 123, a diverging lens 124, a third converging lens 125 and The fourth converging lens 126 ; the first converging lens 122 , the second converging lens 123 , the third converging lens 125 , and the fourth converging lens 126 are used to converge the effective laser beam, and the diverging lens is used to diverge the effective laser beam.

第一激光光束经过第一汇聚透镜122以及第二汇聚透镜123汇聚后,可以成缩小的像,以沿透镜组12的光接收面到光出射面的垂直方向,使构成缩小的像中各个第一激光光束之间的距离减小,相较于第一显示画面,此时的缩小的像的形状更接近于平面;之后,第一激光光束经过发散透镜124成放大的像,且经过发散透镜124所成的放大的像,小于第一激光光束经过第一汇聚透镜122后所成的像,通过将第一激光光束放大,可以满足用户的观看需求,避免用户看到的画面过小;最后,再经过第三汇聚透镜125以及第四汇聚透镜126,再次对第一激光光束进行汇聚,以沿透镜组12的光接收面到光出射面的垂直方向,使构成缩小的像中各个第一激光光束之间的距离趋近于零,即可得到形状为平面的第二显示画面,并且,使得从透镜组12出射的第二激光光束尽可能多地入射到光波导13中。After the first laser beam is converged by the first converging lens 122 and the second converging lens 123, it can be reduced into a reduced image, so that each of the reduced images can be formed along the vertical direction from the light receiving surface to the light emitting surface of the lens group 12. The distance between the laser beams is reduced, and compared with the first display screen, the shape of the reduced image at this time is closer to a plane; after that, the first laser beam passes through the diverging lens 124 to form an enlarged image, and passes through the diverging lens The magnified image formed by 124 is smaller than the image formed by the first laser beam passing through the first converging lens 122. By enlarging the first laser beam, it can meet the user's viewing needs and prevent the user from seeing too small a picture; finally , and then through the third converging lens 125 and the fourth converging lens 126, the first laser beams are converged again, so that each first laser beam in the reduced image can be formed along the vertical direction from the light receiving surface to the light emitting surface of the lens group 12. The distance between the laser beams is close to zero, so that the second display image in the shape of a plane can be obtained, and the second laser beams emitted from the lens group 12 are incident into the optical waveguide 13 as much as possible.

在一些实施例中,光波导13可以对第二激光光束的光路进行调节,光波导13包括光波导本体、藕入光栅、以及藕出光栅。其中,光波导本体可以是衍射型,也可以是全反射型。In some embodiments, the optical waveguide 13 can adjust the optical path of the second laser beam, and the optical waveguide 13 includes an optical waveguide body, an in-coupling grating, and an out-coupling grating. Wherein, the optical waveguide body can be a diffraction type or a total reflection type.

若光波导13是衍射型,则第二激光光束121通过藕入光栅进入光波导13后,可以在光波导13中发生衍射,最终通过藕出光栅以第三激光光束131出射;若光波导13是全反射型,则第二激光光束121通过藕入光栅进入光波导13后,可以在光波导13中发生衍射,最终通过藕出光栅以第三激光光束131出射。If the optical waveguide 13 is a diffractive type, after the second laser beam 121 enters the optical waveguide 13 through the coupling-in grating, it can be diffracted in the optical waveguide 13, and finally exits with the third laser beam 131 through the coupling-out grating; if the optical waveguide 13 If it is a total reflection type, the second laser beam 121 enters the optical waveguide 13 through the in-coupling grating, can be diffracted in the optical waveguide 13, and finally exits as the third laser beam 131 through the out-coupling grating.

在一些实施例中,光纤扫描显示器11可以包括光纤悬臂以及机械驱动结构,机械驱动结构可以驱动光纤悬臂扫描,本申请实施例不对光纤悬臂的扫描方式进行限定。In some embodiments, the fiber-optic scanning display 11 may include a fiber-optic cantilever and a mechanical driving structure, and the mechanical-driving structure may drive the fiber-optic cantilever to scan. The embodiment of the present application does not limit the scanning mode of the fiber-optic cantilever.

可选的,如图6所示,机械驱动结构可以驱动光纤悬臂呈栅格式扫描。在此情况下,机械驱动结构例如可以包括多个压电结构或者多个电磁体。Optionally, as shown in FIG. 6 , the mechanical driving structure can drive the fiber cantilever to scan in a grid format. In this case, the mechanical drive structure may for example comprise a plurality of piezoelectric structures or a plurality of electromagnets.

多个压电结构分设于光纤悬臂的上方、下方、左侧、右侧,或者,多个电磁体分设于光纤悬臂的上方、下方、左侧、右侧。A plurality of piezoelectric structures are respectively arranged above, below, left and right of the fiber cantilever, or a plurality of electromagnets are respectively arranged above, below, left and right of the fiber cantilever.

以机械驱动结构包括多个压电结构为例,压电结构包括依次层叠设置的第一电极层、压电材料层、第二电极层,利用逆压电效应,向第一电极层和第二电极层输入电压,使得压电材料层发生形变,压电材料层发生形变,带动整个压电结构发生形变,进而使得光纤悬臂运动,通过调节作用在多个压电结构上的电压,以调节光纤悬臂的运动方向,从而使光纤悬臂实现栅格式扫描。Taking the mechanical driving structure including multiple piezoelectric structures as an example, the piezoelectric structure includes a first electrode layer, a piezoelectric material layer, and a second electrode layer stacked in sequence. The input voltage of the electrode layer causes the deformation of the piezoelectric material layer, the deformation of the piezoelectric material layer, and the deformation of the entire piezoelectric structure, which in turn causes the fiber cantilever to move. By adjusting the voltage acting on multiple piezoelectric structures, the optical fiber can be adjusted. The direction of motion of the cantilever enables the fiber cantilever to scan in a raster format.

以机械驱动结构包括多个电磁体为例,在电磁体的作用下,光纤悬臂可以朝向电磁体或远离电磁体的方向运动,通过调节多个电磁体的磁性、以及磁场强度,从而使光纤悬臂实现栅格式扫描。Taking the mechanical drive structure including multiple electromagnets as an example, under the action of the electromagnets, the fiber cantilever can move towards the electromagnet or away from the electromagnet. By adjusting the magnetism and magnetic field strength of the multiple electromagnets, the fiber cantilever Realize raster scanning.

在此基础上,光纤扫描显示器11还可以包括机械控制器,在电源管理芯片(PowerManagement IC,简称PMIC)向机械驱动结构提供电源电压的情况下,机械控制器可以控制机械控制器工作。On this basis, the fiber optic scanning display 11 may also include a mechanical controller, and the mechanical controller may control the mechanical controller to work when the power management IC (PMIC) provides power supply voltage to the mechanical driving structure.

在一些实施例中,光纤扫描显示器11还可以包括光源以及控制芯片,光源可以发出激光,作为光纤扫描显示器11的显示光,控制芯片可以控制光源发出的激光的亮度。In some embodiments, the fiber scanning display 11 may further include a light source and a control chip, the light source may emit laser light as the display light of the fiber scanning display 11, and the control chip may control the brightness of the laser light emitted by the light source.

在一些实施例中,如图3所示,不对第一显示画面的形状进行限定,第一显示画面的形状与光纤悬臂的位移轨迹有关。例如,第一显示画面的形状可以是半球面、半椭球面、抛物面、不规则曲面等。在一些实施例中,如图4a所示,不对第二显示画面的具体形状进行限定,只要第二显示画面的形状为平面即可。例如,第二显示画面的形状可以是矩形、圆形、椭圆形等。In some embodiments, as shown in FIG. 3 , the shape of the first display screen is not limited, and the shape of the first display screen is related to the displacement track of the fiber cantilever. For example, the shape of the first display picture may be a hemisphere, a half ellipsoid, a parabola, an irregular curved surface, and the like. In some embodiments, as shown in FIG. 4 a , the specific shape of the second display picture is not limited, as long as the shape of the second display picture is a plane. For example, the shape of the second display picture may be a rectangle, a circle, an ellipse, and the like.

在此基础上,由于第二激光光束121进入光波导13后,在光波导13中发射全反射或衍射,沿光波导13的入光面与光波导13的出光面的垂直方向,发生全反射或衍射的第二激光光束121在所述垂直方向上的路径分量相同,因此,第三显示画面仍为平面。On this basis, since the second laser beam 121 enters the optical waveguide 13, it emits total reflection or diffraction in the optical waveguide 13, and total reflection occurs along the vertical direction between the light incident surface of the optical waveguide 13 and the light exit surface of the optical waveguide 13. Or the path components of the diffracted second laser beam 121 in the vertical direction are the same, therefore, the third display picture is still a plane.

Since the user sees the third display screen of the electronic device 10 instead of the first display screen of the free curved surface when viewing the overall display screen of the electronic device 10, it can improve the user's viewing of the display screen of the electronic device 10. , the problem of visual distortion occurs. On this basis, since the first laser beam 111 emitted from the fiber optic scanning display 11 has good directivity and a small divergence angle, it is more convenient to use the lens group 12 to adjust the first laser beam 111 .

可选的,第一激光光束包括有效激光光束,有效激光光束经透镜组12以及光波导13,以第三激光光束出射,第三激光光束投射的第三显示画面的形状为矩形、且长宽比为预设比例。Optionally, the first laser beam includes an effective laser beam, and the effective laser beam passes through the lens group 12 and the optical waveguide 13 to emerge as a third laser beam, and the shape of the third display screen projected by the third laser beam is rectangular, and the length and width are Ratio is the preset ratio.

其中,预设比例例如可以是4:3,这样一来,用户既可以观看4:3的显示画面,也可以观看16:9的显示画面以及1:1的显示画面等。当然,预设比例也可以是其他比例,本申请实施例对此不作特殊限定。Wherein, the preset ratio may be, for example, 4:3. In this way, the user can not only watch a 4:3 display screen, but also watch a 16:9 display screen and a 1:1 display screen. Certainly, the preset ratio may also be other ratios, which are not specifically limited in this embodiment of the present application.

在一些实施例中,若第一激光光束经透镜组12以及光波导13后,出射的第三激光光束投射的第三显示画面的形状为矩形、且第三显示画面的长宽比为预设比例,则有效激光光束可以等同于第一激光光束;若若第一激光光束经透镜组12以及光波导13后,出射的第三激光光束投射的第三显示画面的形状不为矩形,则有效激光光束可以为第一激光光束的一部分。In some embodiments, if the first laser beam passes through the lens group 12 and the optical waveguide 13, the shape of the third display screen projected by the emitted third laser beam is rectangular, and the aspect ratio of the third display screen is preset ratio, the effective laser beam can be equal to the first laser beam; if the first laser beam passes through the lens group 12 and the optical waveguide 13, the shape of the third display screen projected by the emitted third laser beam is not rectangular, then the effective The laser beam may be part of the first laser beam.

其中,有效激光光束为第一激光光束中实际入射至透镜组12的光线。Wherein, the effective laser beam is the light actually incident on the lens group 12 in the first laser beam.

本申请实施例中,通过将第三显示画面的形状调节为矩形,将所述矩形的长宽比调节为预设比例,可以满足不同电子设备10的显示需求以及不同用户的观看需求。In the embodiment of the present application, by adjusting the shape of the third display screen to be a rectangle and adjusting the aspect ratio of the rectangle to a preset ratio, display requirements of different electronic devices 10 and viewing requirements of different users can be met.

第三显示画面由第三激光光束131投射得到,第三激光光束131为第二激光光束121经光波导13衍射或反射后的光线,第二激光光束121为有效激光光束经过透镜组12出射的光线。因此,可以通过进入透镜组12的有效激光光束,来控制第三显示画面的具体形状。The third display picture is obtained by projecting the third laser beam 131. The third laser beam 131 is the light diffracted or reflected by the second laser beam 121 through the optical waveguide 13. The second laser beam 121 is the effective laser beam emitted by the lens group 12. light. Therefore, the specific shape of the third display screen can be controlled by the effective laser beam entering the lens group 12 .

可选的,如图7a和图7b所示,电子设备10还包括遮光层14,遮光层14设置于光纤扫描显示器11的出光侧,遮光层14用于遮挡第一激光光束111中除有效激光光束以外的其他激光光束。Optionally, as shown in Figures 7a and 7b, the electronic device 10 further includes a light-shielding layer 14, the light-shielding layer 14 is arranged on the light-emitting side of the optical fiber scanning display 11, and the light-shielding layer 14 is used to shield the first laser beam 111 except the effective laser beam Beams other than laser beams.

可以通过遮光层14遮挡,使第一激光光束111中除有效激光光束以外的其他光线被遮光层14吸收或反射,从而无法从光纤扫描显示器11出射。这样一来,即可通过调节遮光层14的设置位置,确定第一激光光束111中属于有效激光光束的部分,进而调节第三显示画面的形状。The light shielding layer 14 can be used to shield the first laser beam 111 except for the effective laser beam to be absorbed or reflected by the light shielding layer 14 , so that it cannot be emitted from the fiber optic scanning display 11 . In this way, by adjusting the position of the light-shielding layer 14 , the part of the first laser beam 111 that belongs to the effective laser beam can be determined, and then the shape of the third display screen can be adjusted.

其中,由于从光纤扫描显示器11出射的第一激光光束111的发散角度较小,因此,有效激光光束基本为小角度的光线。从光纤扫描显示器11中未被遮光层14遮挡、且距离遮光层14较近的部分出射的光线中,具有一定发散角的部分的发散角较小,且光强较小,因此,在环境光线的干扰下,用户实际看到的第三显示画面为长宽比为预设比例的矩形,其他光线可以忽略不计。Wherein, since the divergence angle of the first laser beam 111 emitted from the optical fiber scanning display 11 is relatively small, the effective laser beam is basically a light with a small angle. Among the light emitted from the part of the optical fiber scanning display 11 that is not blocked by the light-shielding layer 14 and is closer to the light-shielding layer 14, the part with a certain divergence angle has a smaller divergence angle and a lower light intensity. Therefore, in the ambient light Under the interference of the ray, the third display image that the user actually sees is a rectangle with a preset aspect ratio, and other light rays can be ignored.

在一些实施例中,不对遮光层14的具体设置位置进行限定,只要第三显示画面为矩形,且矩形的长宽比满足预设比例即可。In some embodiments, the specific location of the light-shielding layer 14 is not limited, as long as the third display frame is a rectangle, and the aspect ratio of the rectangle satisfies a preset ratio.

为了使第一激光光束111更多地应用于显示,以在相同显示亮度下,减小光纤扫描显示器11的功耗,可选将遮光层14设置在显示区中靠近边框区的边缘区域,且遮光层14尽可能少地覆盖光纤扫描显示器11的显示区。In order to make the first laser beam 111 more applied to the display, so as to reduce the power consumption of the optical fiber scanning display 11 under the same display brightness, the light shielding layer 14 can optionally be arranged in the edge area of the display area close to the frame area, and The light-shielding layer 14 covers the display area of the fiber optic scanning display 11 as little as possible.

本申请实施例中,可以通过遮光层14遮挡,使第一激光光束111中除有效激光光束以外的其他光线被遮光层14遮挡,仅使有效激光光束出射并用于显示,从而使第三显示画面的形状为矩形,且矩形的长宽比满足预设比例。In the embodiment of the present application, the light-shielding layer 14 can be used to shield the first laser beam 111 except for the effective laser beam. The shape of is a rectangle, and the aspect ratio of the rectangle satisfies the preset ratio.

The range of the beam.

本申请实施例中,通过使有效激光光束投射到透镜组12上的范围,与透镜组12的光接收面的范围相同,从而使有效激光光束入射到透镜组12,避免第一激光光束111中除有效激光光束以外的光线进入透镜组12中。In the embodiment of the present application, by making the range of the effective laser beam projected on the lens group 12 the same as the range of the light receiving surface of the lens group 12, the effective laser beam is incident on the lens group 12, avoiding the first laser beam 111 Light rays other than the active laser beam enter the lens group 12 .

此外,也可以通过其他方式,仅使第一激光光束111中的有效激光光束入射至透镜组12,并用于显示,本申请实施例对此不作特殊限定。In addition, only the effective laser beams of the first laser beams 111 may be incident on the lens group 12 and used for display in other ways, which is not specifically limited in this embodiment of the present application.

在一些实施例中,不对光纤扫描显示器11以及透镜组12的具体设置位置进行限定。光纤扫描显示器11以及透镜组12可以设置在镜架15的不同位置,其中,透镜组12可以靠近光波导13设置。In some embodiments, the specific arrangement positions of the fiber optic scanning display 11 and the lens group 12 are not limited.

为了避免在用户余光范围内看到光纤扫描显示器11以及透镜组12,从而影响用户的观看体验,本申请实施例可以在不影响有效激光光束入射至透镜组12、第二激光光束121入射至光波导13的情况下,将光纤扫描显示器11以及透镜组12尽可能地向远离镜框的位置设置。例如,在用户佩戴AR眼镜时,光纤扫描显示器11以及透镜组12在镜架位于脑后的位置。In order to avoid seeing the fiber optic scanning display 11 and the lens group 12 in the peripheral vision range of the user, thereby affecting the viewing experience of the user, the embodiment of the present application can not affect the effective laser beam incident on the lens group 12, the second laser beam 121 incident on the In the case of the optical waveguide 13, the optical fiber scanning display 11 and the lens group 12 are arranged as far away from the lens frame as possible.

在一些实施例中,不对透镜组12的具体组成以及各个组成部分的具体参数进行限定,只要进入透镜组12的第一激光光束111从透镜组12以第二激光光束121出射后,第二激光光束121投射的第二显示画面为平面即可。In some embodiments, the specific composition of the lens group 12 and the specific parameters of each component are not limited, as long as the first laser beam 111 entering the lens group 12 exits the lens group 12 as the second laser beam 121, the second laser beam The second display image projected by the light beam 121 only needs to be a plane.

其中,可以采集从光纤扫描显示器11出射的第一激光光束在各个像素点的光路,根据第一激光光束构成的自由曲面面型、平面面型的成像面、以及第二激光光束121的出射方向之间的几何位置关系,利用光学软件进行拟合,可以得到透镜组12的具体组成以及各个组成部分的具体参数。第一激光光束111进入透镜组12后,可以根据透镜组12的具体组成,在透镜组12中经过至少一次成像。Wherein, the optical path of the first laser beam emitted from the optical fiber scanning display 11 at each pixel point can be collected, according to the free-form surface type, the imaging surface of the planar surface type formed by the first laser beam, and the emission direction of the second laser beam 121 The geometric positional relationship among them is fitted by using optical software, and the specific composition of the lens group 12 and the specific parameters of each component can be obtained. After the first laser beam 111 enters the lens group 12 , it may be imaged in the lens group 12 at least once according to the specific composition of the lens group 12 .

The distance between the laser beams is reduced, and compared with the first display screen, the shape of the reduced image at this time is closer to a plane; after that, the first laser beam passes through the diverging lens 124 to form an enlarged image, and passes through the diverging lens The magnified image formed by 124 is smaller than the image formed by the first laser beam passing through the first converging lens 122. By enlarging the first laser beam, it can meet the user's viewing needs and prevent the user from seeing too small a picture; finally , and then through the third converging lens 125 and the fourth converging lens 126, the first laser beams are converged again, so that each first laser beam in the reduced image can be formed along the vertical direction from the light receiving surface to the light emitting surface of the lens group 12. The distance between the laser beams is close to zero, and the second display picture in the shape of a plane can be obtained.

Wherein, the optical waveguide body can be a diffraction type or a total reflection type.

若光波导13是衍射型,则第二激光光束121通过藕入光栅进入光波导13后,可以在光波导13中发生衍射,最终通过藕出光栅以第三激光光束131出射;若光波导13是全反射型,则第二激光光束121通过藕入光栅进入光波导13后,可以在光波导13中发生衍射,最终通过藕出光栅以第三激光光束131出射。If the optical waveguide 13 is a diffractive type, after the second laser beam 121 enters the optical waveguide 13 through the coupling-in grating, it can be diffracted in the optical waveguide 13, and finally exits with the third laser beam 131 through the coupling-out grating; if the optical waveguide 13 If it is a total reflection type, the second laser beam 121 enters the optical waveguide 13 through the in-coupling grating, can be diffracted in the optical waveguide 13, and finally exits as the third laser beam 131 through the out-coupling grating.

在一些实施例中,由于第二激光光束121构成的第二显示画面的形状为平面,且第二激光光束121进入光波导13后,在光波导13中发射全反射或衍射,沿光波导13的入光面与光波导13的出光面的垂直方向,发生全反射或衍射的第二激光光束121在所述垂直方向上的路径分量相同,因此,第三显示画面仍为平面。In some embodiments, since the shape of the second display picture formed by the second laser beam 121 is a plane, and after the second laser beam 121 enters the optical waveguide 13, it emits total reflection or diffraction in the optical waveguide 13, and along the optical waveguide 13 In the vertical direction between the light incident surface of the optical waveguide 13 and the light exit surface of the optical waveguide 13, the path components of the totally reflected or diffracted second laser beam 121 in the vertical direction are the same, therefore, the third display screen is still a plane.

Since the user sees the third display screen of the electronic device 10 instead of the first display screen of the free curved surface when viewing the overall display screen of the electronic device 10, it can improve the user's viewing of the display screen of the electronic device 10. , the problem of visual distortion occurs. On this basis, since the first laser beam 111 emitted from the fiber optic scanning display 11 has good directivity and a small divergence angle, it is more convenient to use the lens group 12 to adjust the first laser beam 111 .

可选的,第一激光光束包括有效激光光束,有效激光光束经透镜组12以及光波导13,以第三激光光束出射,第三激光光束投射的第三显示画面的形状为平面、且长宽比为预设比例。Optionally, the first laser beam includes an effective laser beam, and the effective laser beam passes through the lens group 12 and the optical waveguide 13 to emerge as a third laser beam, and the shape of the third display screen projected by the third laser beam is plane, and the length and width are Ratio is the preset ratio.

其中,预设比例例如可以是4:3,这样一来,用户既可以观看4:3的显示画面,也可以观看16:9的显示画面以及1:1的显示画面等。当然,预设比例也可以是其他比例,本申请实施例对此不作特殊限定。Wherein, the preset ratio may be, for example, 4:3. In this way, the user can not only watch a 4:3 display screen, but also watch a 16:9 display screen and a 1:1 display screen. Of course, the preset ratio may also be other ratios, which are not specifically limited in this embodiment of the present application.

在一些实施例中,若第一激光光束经透镜组12以及光波导13后,出射的第三激光光束投射的第三显示画面的形状为矩形、且第三显示画面的长宽比为预设比例,则有效激光光束可以等同于第一激光光束;若若第一激光光束经透镜组12以及光波导13后,出射的第三激光光束投射的第三显示画面的形状不为矩形,则有效激光光束可以为第一激光光束的一部分。In some embodiments, if the first laser beam passes through the lens group 12 and the optical waveguide 13, the shape of the third display screen projected by the emitted third laser beam is rectangular, and the aspect ratio of the third display screen is preset ratio, the effective laser beam can be equal to the first laser beam; if the first laser beam passes through the lens group 12 and the optical waveguide 13, the shape of the third display screen projected by the emitted third laser beam is not rectangular, then the effective The laser beam may be part of the first laser beam.

其中,有效激光光束为第一激光光束中实际入射至透镜组12的光线。Wherein, the effective laser beam is the light actually incident on the lens group 12 in the first laser beam.

本申请实施例中,通过将第三显示画面的形状调节为矩形,将所述矩形的长宽比调节为预设比例,可以满足不同电子设备10的显示需求以及不同用户的观看需求。In the embodiment of the present application, by adjusting the shape of the third display screen to be a rectangle and adjusting the aspect ratio of the rectangle to a preset ratio, display requirements of different electronic devices 10 and viewing requirements of different users can be met.

在此基础上,第三显示画面由第三激光光束131投射得到,第三激光光束131为第二激光光束121经光波导13衍射或反射后的光线,第二激光光束121为有效激光光束经过透镜组12出射的光线。因此,可以通过进入透镜组12的有效激光光束,来控制第三显示画面的具体形状。On this basis, the third display picture is obtained by projecting the third laser beam 131. The third laser beam 131 is the light diffracted or reflected by the second laser beam 121 through the optical waveguide 13. The second laser beam 121 is the effective laser beam passing through The light emitted by the lens group 12. Therefore, the specific shape of the third display screen can be controlled by the effective laser beam entering the lens group 12 .

可选的,如图7a和图7b所示,电子设备10还包括遮光层14,遮光层14设置于光纤扫描显示器11的出光侧,遮光层14用于遮挡第一激光光束111中除有效激光光束以外的其他激光光束。Optionally, as shown in Figures 7a and 7b, the electronic device 10 further includes a light-shielding layer 14, the light-shielding layer 14 is arranged on the light-emitting side of the optical fiber scanning display 11, and the light-shielding layer 14 is used to shield the first laser beam 111 except the effective laser beam Beams other than laser beams.

可以通过遮光层14遮挡,使第一激光光束111中除有效激光光束以外的其他光线被遮光层14吸收或反射,从而无法从光纤扫描显示器11出射。这样一来,即可通过调节遮光层14的设置位置,确定第一激光光束111中属于有效激光光束的部分,进而调节第三显示画面的形状。The light shielding layer 14 can be used to shield the first laser beam 111 except for the effective laser beam to be absorbed or reflected by the light shielding layer 14 , so that it cannot be emitted from the fiber optic scanning display 11 . In this way, by adjusting the position of the light-shielding layer 14 , the part of the first laser beam 111 that belongs to the effective laser beam can be determined, and then the shape of the third display screen can be adjusted.

其中,由于从光纤扫描显示器11出射的第一激光光束111的发散角度较小,因此,有效激光光束基本为小角度的光线。从光纤扫描显示器11中未被遮光层14遮挡、且距离遮光层14较近的部分出射的光线中,具有一定发散角的部分的发散角较小,且光强较小,因此,在环境光线的干扰下,用户实际看到的第三显示画面为长宽比为预设比例的矩形,其他光线可以忽略不计。Wherein, since the divergence angle of the first laser beam 111 emitted from the optical fiber scanning display 11 is relatively small, the effective laser beam is basically a light with a small angle. Among the light emitted from the part of the optical fiber scanning display 11 that is not blocked by the light-shielding layer 14 and is closer to the light-shielding layer 14, the part with a certain divergence angle has a smaller divergence angle and a lower light intensity. Therefore, in the ambient light Under the interference of the ray, the third display image that the user actually sees is a rectangle with a preset aspect ratio, and other light rays can be ignored.

在一些实施例中,不对遮光层14的具体设置位置进行限定,只要第三显示画面为矩形,且矩形的长宽比满足预设比例即可。In some embodiments, the specific location of the light-shielding layer 14 is not limited, as long as the third display frame is a rectangle, and the aspect ratio of the rectangle satisfies a preset ratio.

示例的,如图7a所示,光纤扫描显示器11包括显示区以及位于显示区外围的边框区,遮光层14可以设置在显示区中靠近边框区的边缘区域;如图7b所示,遮光层14也可以设置在半个完整的显示区。Exemplarily, as shown in Figure 7a, the fiber optic scanning display 11 includes a display area and a frame area located at the periphery of the display area, and the light-shielding layer 14 can be arranged in the edge area of the display area close to the frame area; as shown in Figure 7b, the light-shielding layer 14 It can also be set in half of the complete display area.

为了使第一激光光束111更多地应用于显示,以在相同显示亮度下,减小光纤扫描显示器11的功耗,可选将遮光层14设置在显示区中靠近边框区的边缘区域,且遮光层14尽可能少地覆盖光纤扫描显示器11的显示区。In order to make the first laser beam 111 more applied to the display, so as to reduce the power consumption of the optical fiber scanning display 11 under the same display brightness, the light shielding layer 14 can optionally be arranged in the edge area of the display area close to the frame area, and The light-shielding layer 14 covers the display area of the fiber optic scanning display 11 as little as possible.

本申请实施例中,可以通过遮光层14遮挡,使第一激光光束111中除有效激光光束以外的其他光线被遮光层14遮挡,仅使有效激光光束出射并用于显示,从而使第三显示画面的形状为矩形,且矩形的长宽比满足预设比例。In the embodiment of the present application, the light-shielding layer 14 can be used to shield the first laser beam 111 except for the effective laser beam. The shape of is a rectangle, and the aspect ratio of the rectangle satisfies the preset ratio.

可选的,如图8所示,透镜组12设置于光纤扫描显示器11的出光侧,有效激光光束投射到透镜组12上的范围,与透镜组12的光接收面的范围相同。Optionally, as shown in FIG. 8 , the lens group 12 is arranged on the light-emitting side of the fiber optic scanning display 11 , and the range of the effective laser beam projected onto the lens group 12 is the same as the range of the light-receiving surface of the lens group 12 .

可以通过调节透镜组12与光纤扫描显示器11的相对位置关系、以及透镜组12的光接收面在透镜组12中的位置,来调节第一激光光束111中可以入射到透镜组12中的有效激光光束的范围。The effective laser light that can be incident in the lens group 12 in the first laser beam 111 can be adjusted by adjusting the relative positional relationship between the lens group 12 and the optical fiber scanning display 11, and the position of the light-receiving surface of the lens group 12 in the lens group 12. The range of the beam.

本申请实施例中,通过使有效激光光束投射到透镜组12上的范围,与透镜组12的光接收面的范围相同,从而使有效激光光束入射到透镜组12,避免第一激光光束111中除有效激光光束以外的光线进入透镜组12中。In the embodiment of the present application, by making the range of the effective laser beam projected on the lens group 12 the same as the range of the light receiving surface of the lens group 12, the effective laser beam is incident on the lens group 12, avoiding the first laser beam 111 Light rays other than the active laser beam enter the lens group 12 .
