The optical fiber scanning display is used to emit the first laser beam, and the first display picture projected by the first laser beam is a free-form surface. The lens group, the first laser beam enters the lens group and exits as the second laser beam, and the second display picture projected by the second laser beam is a plane. The optical waveguide, the second laser beam enters the optical waveguide and exits as the third laser beam, and the third display picture projected by the third laser beam is a plane.
第二方面,提供一种AR眼镜,AR眼镜本体包括镜架,光纤扫描显示器以及透镜组设置于镜架上。In a second aspect, AR glasses are provided. The AR glasses body includes a frame, and a fiber optic scanning display and a lens group are arranged on the frame.
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. The lens group can correct the optical path of the first laser beam, so that the light emitted from the lens group The second display image projected by the second laser beam is flat, and after the second laser beam is reflected or diffracted by the optical waveguide, the third display image projected by the outgoing third laser beam is still flat. 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.

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
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
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
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

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

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

本申请实施例提供一种电子设备10,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。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为自由曲面,可以在光纤扫描显示器11的出光侧设置透镜组12,透镜组12可以对第一激光光束的光路进行校正,使从透镜组12出射的第二激光光束121投射的第二显示画面为平面,进而第二激光光束121经过光波导13进行反射或衍射后,出射的第三激光光束131投射的第三显示画面仍为平面。由于用户在观看电子设备10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10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11出射的第一激光光束111的方向性好、发散角度较小,因此,更便于利用透镜组12对第一激光光束111进行调节。An embodiment of the present application provides an
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
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
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
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
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
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
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
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
