具体实施方式Detailed ways

下面将结合附图，对本发明实施例中的技术方案进行描述。The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings.

图2是根据本发明实施例的近眼显示系统的示意图。如图2所示，近眼显示系统包括：近眼显示器、控制芯片、电池、收发信机和天线。FIG. 2 is a schematic diagram of a near-eye display system according to an embodiment of the present invention. As shown in Figure 2, the near-eye display system includes: a near-eye display, a control chip, a battery, a transceiver and an antenna.

近眼显示器用于将图像投射到用户的眼睛内，并实现对外部图像的采集功能。控制芯片用于将数字图像信号转化为近眼显示器的显示部件的驱动电流强弱及时序信号，并通过隐藏在镜框内的金属连线连接到近眼显示器，驱动近眼显示器的显示部件进行图像呈现；同时将近眼显示器的摄像部件采集到的图像的电信号转化为数字图像信号。电池为整个近眼显示系统提供电源。收发信机及天线用于从移动终端接收通过无线链路传输的数字图像信号，并传送给控制芯片；同时从控制芯片获取摄像部件采集到的图像的数字图像信号，发送给终端设备。其中，可选地，该收发信机具体可以是无线收发信机。The near-eye display is used to project the image into the user's eyes and realize the function of collecting external images. The control chip is used to convert the digital image signal into the driving current strength and timing signal of the display component of the near-eye display, and is connected to the near-eye display through the metal connection hidden in the frame to drive the display component of the near-eye display for image presentation; The electrical signal of the image collected by the imaging component of the near-eye display is converted into a digital image signal. The battery provides power for the entire near-eye display system. The transceiver and the antenna are used to receive the digital image signal transmitted by the wireless link from the mobile terminal and transmit it to the control chip; meanwhile, the digital image signal of the image collected by the camera unit is obtained from the control chip and sent to the terminal device. Wherein, optionally, the transceiver may specifically be a wireless transceiver.

如图2所示，近眼显示系统可以包括两个近眼显示器，左侧近眼显示器和右侧近眼显示器，该两个近眼显示器分别对应于用户的左眼和右眼，这样用户的双眼都可以看到采用AR显示技术的增强实景图像。但本发明实施例对此并不限定，近眼显示系统还可以只包括一个近眼显示器，该近眼显示器对应于用户的左眼或右眼，这样用户对应于近眼显示器的眼睛可以看到采用AR显示技术的增强实景图像或采用VR显示技术的立体视觉图像。As shown in FIG. 2 , the near-eye display system may include two near-eye displays, a left near-eye display and a right near-eye display, the two near-eye displays respectively correspond to the user's left eye and right eye, so that both eyes of the user can see Augmented reality images with AR display technology. However, the embodiment of the present invention is not limited to this. The near-eye display system may also include only one near-eye display, and the near-eye display corresponds to the user's left eye or right eye, so that the user's eyes corresponding to the near-eye display can see the AR display technology. augmented reality images or stereoscopic images using VR display technology.

也就是说，本发明实施例中的近眼显示器可以看作是近眼显示系统中的一个镜片。That is to say, the near-eye display in the embodiment of the present invention can be regarded as a lens in the near-eye display system.

需要说明的是，本发明实施例中的控制芯片也可以称为驱动芯片。It should be noted that, the control chip in the embodiment of the present invention may also be referred to as a driver chip.

如图3所示，本发明实施例提供的近眼显示器可以包括摄像显示面板310和第一折射结构320。其中摄像显示面板310包括平铺设置的多个摄像显示单元311。其中，每个摄像显示单元311包括沿所述摄像显示面板310的厚度方向叠加的摄像部件3111和显示部件3112，摄像部件3111位于显示部件3112的背面。As shown in FIG. 3 , the near-eye display provided by the embodiment of the present invention may include acamera display panel 310 and afirst refraction structure 320 . Thecamera display panel 310 includes a plurality ofcamera display units 311 arranged in tiles. Wherein, eachimaging display unit 311 includes animaging component 3111 and adisplay component 3112 superimposed along the thickness direction of theimaging display panel 310 , and theimaging component 3111 is located on the back of thedisplay component 3112 .

应理解，显示部件3112的背面与显示部件3112的表面正对。显示部件3112的表面能够发光，通过控制摄像显示面板310上的多个摄像显示单元311的显示部件3112的发光，能够显示图像。It should be understood that the rear surface of thedisplay part 3112 is directly opposite to the surface of thedisplay part 3112 . The surface of thedisplay part 3112 can emit light, and images can be displayed by controlling the light emission of thedisplay parts 3112 of the plurality ofimaging display units 311 on theimaging display panel 310 .

该多个摄像显示单元311平铺设置在摄像显示面板310内，具体是指：该多个摄像显示单元311在垂直于摄像显示面板310的方向上互不重叠，每个摄像显示单元311在垂直于摄像显示面板310的方向上不会对其他摄像显示单元311输出的光线造成遮挡。The plurality of imaging anddisplay units 311 are arranged in a tiled manner in the imaging anddisplay panel 310, specifically, the plurality of imaging anddisplay units 311 do not overlap each other in the direction perpendicular to the imaging anddisplay panel 310, and each imaging anddisplay unit 311 is perpendicular to the imaging anddisplay panel 310. The direction of thecamera display panel 310 will not block the light output by othercamera display units 311 .

每个摄像部件3111用于拍摄照片或视频，每个显示部件3112用于显示图像。具体的，每个摄像部件3111用于接收来自被摄对象的光线，并将来自被摄对象的光线进行光电转换生成电信号。每个显示部件3112用于发光，通过控制摄像显示面板310内的多个摄像显示单元311的显示部件3112的发光，摄像显示面板310的显示部件3112的表面可以显示图像。Eachcamera part 3111 is used for taking pictures or videos, and eachdisplay part 3112 is used for displaying images. Specifically, eachimaging component 3111 is used to receive light from a subject, and photoelectrically convert the light from the subject to generate an electrical signal. Eachdisplay part 3112 is used to emit light, and by controlling the light emission of thedisplay parts 3112 of the plurality ofimaging display units 311 in theimaging display panel 310 , the surface of thedisplay parts 3112 of theimaging display panel 310 can display images.

第一折射结构320设置在摄像显示面板310的发光侧(即显示部件3112的表面)，用于将摄像显示面板310输出的光线折射到近眼显示器的焦点处，近眼显示器的焦点落在用户的眼球内。Thefirst refraction structure 320 is disposed on the light-emitting side of the camera display panel 310 (ie, the surface of the display component 3112 ), and is used to refract the light output from thecamera display panel 310 to the focal point of the near-eye display, and the focus of the near-eye display falls on the user's eyeball Inside.

具体地，每个摄像显示单元311的显示部件输出的光线组成光柱，该光柱经过第一折射结构320折射后光柱的中心指向近眼显示器的焦点处。Specifically, the light output from the display component of eachcamera display unit 311 forms a light beam, and the center of the light beam is refracted by thefirst refraction structure 320 and points to the focal point of the near-eye display.

需要说明的是，近眼显示器的焦点是指准直光经过该近眼显示器之后被汇聚到的一个点，这个点即为该近眼显示器的焦点。所谓的准直光是相对于发散光来说的，通常光线是发散的，即开始相邻的两条光线传播后会相离越来越远。光线自光源处发出后，出射光锥的发散角小于或等于特定的角度(例如，在本发明实施例中，该特定角度可以小于或等于5°)，则可认为该光源发出的多条光线互相平行，为准直光。准直光通俗说就是多条光线之间大致是平行的。It should be noted that the focus of the near-eye display refers to a point where the collimated light is converged after passing through the near-eye display, and this point is the focus of the near-eye display. The so-called collimated light is relative to the divergent light, usually the light is divergent, that is, the two adjacent light rays will be farther and farther apart after they start to propagate. After the light is emitted from the light source, the divergence angle of the outgoing light cone is less than or equal to a specific angle (for example, in this embodiment of the present invention, the specific angle may be less than or equal to 5°), then it can be considered that the light source emits multiple rays of light parallel to each other for collimated light. Collimated light is generally said to be roughly parallel between multiple rays.

在本发明实施例中，近眼显示器包括摄像显示面板和第一折射结构，所以在本发明实施例中，摄像显示面板的显示部件输出的光线是经过第一折射结构之后，被折射到该近眼显示器的焦点处的。此外，本领域技术人员都知道，为了让用户能够更清楚地看清近眼显示器显示的图像，可选地，近眼显示器的焦点会落在用户的眼球中。具体地，近眼显示器的焦点落在用户的瞳孔圆心的中轴线上。本实施例及其他实施例中，如无特殊说明，近眼显示器的焦点也均落在用户的瞳孔圆心的中轴线上。还需要说明的是，用户佩戴近眼显示器之后，如果用户的眼球发生了转动，则近眼显示器的焦点可能无法落在用户的瞳孔的圆心的中轴线上，此时可以由用于支撑近眼显示器的器件(如促动器)自动跟踪用户的眼球转动，并自动调整近眼显示器的位置，使得近眼显示器的焦点落在用户的瞳孔的圆心的中轴线上。这样，当用户的眼球发生转动时，用户无需手动调整近眼显示器即可看到清晰的图像，能够提升用户的使用体验。In the embodiment of the present invention, the near-eye display includes an imaging display panel and a first refraction structure, so in the embodiment of the present invention, the light output by the display component of the imaging display panel is refracted to the near-eye display after passing through the first refraction structure of focus. In addition, those skilled in the art know that, in order to allow the user to see the image displayed by the near-eye display more clearly, optionally, the focus of the near-eye display will fall on the user's eyeball. Specifically, the focal point of the near-eye display falls on the central axis of the center of the pupil of the user. In this embodiment and other embodiments, unless otherwise specified, the focus of the near-eye display also falls on the central axis of the center of the pupil of the user. It should also be noted that after the user wears the near-eye display, if the user's eyeball rotates, the focus of the near-eye display may not be able to fall on the central axis of the center of the user's pupil. (eg, an actuator) automatically tracks the user's eyeball rotation, and automatically adjusts the position of the near-eye display so that the focus of the near-eye display falls on the central axis of the center of the user's pupil. In this way, when the user's eyeball rotates, the user can see a clear image without manually adjusting the near-eye display, which can improve the user's experience.

使用促动器等支撑部件调整该近眼显示器的位置时，还可以结合用户的头型或脸型等进行调整，这样能够更加精确地调整该近眼显示器的位置。When adjusting the position of the near-eye display using a supporting member such as an actuator, the adjustment can also be performed in combination with the user's head shape or face shape, etc., so that the position of the near-eye display can be adjusted more accurately.

可选地，第一折射结构320的基材可以为透明基材。Optionally, the substrate of thefirst refraction structure 320 may be a transparent substrate.

可选地，如图4所示，多个摄像显示单元311中的每两个相邻摄像显示单元311间隔设置，且每两个相邻摄像显示单元311之间填充有透光的透明基材。这样的设计能够使得外部实景光线透过相邻摄像显示单元之间的透明基材进入用户的眼睛。而且，将多个摄像显示单元的显示部件平铺设置在整个近眼显示器上，还能够提供较大的视场范围，进而能够提升用户的视觉体验。Optionally, as shown in FIG. 4 , every two adjacentcamera display units 311 in the plurality ofcamera display units 311 are arranged at intervals, and a transparent base material that transmits light is filled between every two adjacentcamera display units 311 . . Such a design enables external real-world light to enter the user's eyes through the transparent base material between adjacent camera display units. Moreover, the display components of the multiple camera display units are arranged in a tile on the entire near-eye display, which can also provide a larger field of view, thereby improving the user's visual experience.

还需要说明的是，第一折射结构320中与每两个摄像显示单元311之间间隔的透明基材正对的部分允许外界光线无畸变通过。可选地，第一折射结构320中与每两个摄像显示单元311之间间隔的透明基材正对的部分也可以为透明基材。It should also be noted that, the portion of thefirst refraction structure 320 that is directly opposite to the transparent substrate spaced between every twocamera display units 311 allows external light to pass through without distortion. Optionally, the part of thefirst refraction structure 320 that faces the transparent substrate spaced between every twocamera display units 311 may also be a transparent substrate.

可选地，摄像显示面板310还可以包括透明基板，多个摄像显示单元311可以间隔放置在摄像显示面板310的透明基板上。Optionally, thecamera display panel 310 may further include a transparent substrate, and a plurality ofcamera display units 311 may be placed on the transparent substrate of thecamera display panel 310 at intervals.

通过在摄像显示面板上设置多个摄像显示单元，并且在任意两个相邻摄像显示单元之间的间隔处采用透明基材，使得外部实景光线能够通过任意两个摄像显示单元之间的间隔，从而实现外部实景图像与摄像显示单元显示的图像的叠加。By arranging a plurality of camera display units on the camera display panel, and using a transparent substrate at the interval between any two adjacent camera display units, the external real scene light can pass through the interval between any two camera display units, Thereby, the superposition of the external real scene image and the image displayed by the camera display unit is realized.

本发明实施例中的透明基材可以是玻璃或透明性树脂，但本发明实施例对此并不限定，该透明基材还可以是其他能够透光的材料。需要说明的是，本发明实施例对透明基材的透光率也不做限定，例如，该透明基材的透光率可以为80％～95％。透明基材的透光率越高，人们佩戴近眼显示器时看到的图像的质量越高。可选地，透明基材覆盖任意两个相邻摄像显示单元之间的全部间隔，从而最大可能提升透光率。The transparent substrate in the embodiment of the present invention may be glass or transparent resin, but the embodiment of the present invention is not limited thereto, and the transparent substrate may also be other materials that can transmit light. It should be noted that the embodiment of the present invention does not limit the light transmittance of the transparent substrate, for example, the light transmittance of the transparent substrate may be 80% to 95%. The higher the light transmittance of the transparent substrate, the higher the quality of the image people see when wearing a near-eye display. Optionally, the transparent substrate covers the entire interval between any two adjacent camera display units, so as to maximize the light transmittance.

在一些实施例中，多个摄像显示单元311可以布置为M行×N列的矩阵形状，M和N均为大于或等于1的整数。但本发明实施例对此并不限定，多个摄像显示单元311还可以布置为其他规则形状或不规则形状。In some embodiments, the plurality ofcamera display units 311 may be arranged in a matrix shape of M rows×N columns, where M and N are both integers greater than or equal to 1. However, the embodiment of the present invention is not limited to this, and the plurality ofcamera display units 311 may also be arranged in other regular shapes or irregular shapes.

相邻摄像显示单元可以指在一个或多个指定方向上相邻的摄像显示单元，该指定方向可以根据摄像显示单元的布置形状确定。例如，多个摄像显示单元311布置为矩阵形状，相邻摄像显示单元指的是在行方向和/或列方向上相邻的摄像显示单元。Adjacent imaging and display units may refer to imaging and display units that are adjacent in one or more specified directions, and the specified directions may be determined according to the arrangement shape of the imaging and display units. For example, a plurality of imagepickup display units 311 are arranged in a matrix shape, and adjacent image pickup display units refer to image pickup display units that are adjacent in a row direction and/or a column direction.

应理解，每两个相邻摄像显示单元间隔设置是指设置的两个相邻摄像显示单元之间存在一定的间隔距离，该间隔距离可以根据实际的产品进行调整。间隔距离越大，透光率越高，但是图像质量越差。间隔距离越小，透光率越低，图像质量越高。It should be understood that every two adjacent camera display units are arranged at intervals, which means that there is a certain distance between the two adjacent camera display units, and the distance can be adjusted according to actual products. The larger the separation distance, the higher the light transmittance, but the worse the image quality. The smaller the separation distance, the lower the light transmittance and the higher the image quality.

在一些实施例中，每两个相邻摄像显示单元之间的间隔距离相同，这样有利于简化近眼显示器的生产工艺。但本发明实施例对此并不限定，每两个相邻摄像显示单元之间的间隔距离也可以不同，或者部分相邻摄像显示单元之间的间隔距离相同。例如，多个摄像显示单元311布置为矩阵形状，在行方向和/或列方向上相邻的两个摄像显示单元之间的间隔距离相同；或者，在行方向上相邻的两个摄像显示单元之间间隔第一距离，在列方向上相邻的两个摄像显示单元之间间隔第二距离，且第一距离与第二距离不同。In some embodiments, the separation distance between every two adjacent camera display units is the same, which is beneficial to simplify the production process of the near-eye display. However, the embodiment of the present invention is not limited to this, and the separation distance between every two adjacent camera display units may also be different, or the separation distance between some adjacent camera display units may be the same. For example, the plurality of imaging anddisplay units 311 are arranged in a matrix shape, and the spacing distance between two adjacent imaging and display units in the row direction and/or the column direction is the same; or, two adjacent imaging and display units in the row direction. There is a first distance therebetween, and a second distance is between two adjacent imaging and display units in the column direction, and the first distance is different from the second distance.

由于人眼视觉对视黄斑部分的分辨率高，而对边缘部分的分辨率较低，因此在一些实施例中，还可以根据摄像显示单元距离摄像显示面板中心(即近眼显示器镜片中心)的距离来设置摄像显示单元之间的间隔距离。例如距离摄像显示面板中心越远，摄像显示单元之间的间隔越大，这样并不会影响用户的视觉体验。Since human vision has high resolution on the macular part and low resolution on the edge part, in some embodiments, the distance between the camera display unit and the center of the camera display panel (that is, the center of the near-eye display lens) can also be determined according to the to set the separation distance between the camera display units. For example, the farther from the center of the camera display panel, the greater the interval between the camera display units, which will not affect the user's visual experience.

本发明实施例的近眼显示器中，通过在摄像显示面板的发光侧设置折射结构，将摄像显示面板的显示部件显示的图像折射到用户的眼睛内，同时外界的实景光线穿过摄像显示单元之间的透明基材进入用户的眼睛，能够实现摄像显示面板显示的虚拟图像与外部实景图像叠加的AR显示。同时，将摄像显示单元排列在整个摄像显示面板上，这样能够提供较大的视场范围，进而能够提升用户的视觉体验。In the near-eye display of the embodiment of the present invention, by disposing a refracting structure on the light-emitting side of the camera display panel, the image displayed by the display part of the camera display panel is refracted into the user's eyes, and at the same time, the real light from the outside world passes between the camera display units. The transparent substrate can enter the user's eyes, which can realize AR display in which the virtual image displayed on the camera display panel is superimposed with the external real image. At the same time, the camera display units are arranged on the entire camera display panel, which can provide a larger field of view, thereby improving the user's visual experience.

进一步地，通过将显示部件和摄像部件集成为摄像显示单元，在实现AR显示的同时还可以实现摄像功能，且摄像视角与人眼视角一致，即实现AR摄像“所见即所得”。同时，由于近眼显示器无需额外配置摄像装置，有利于降低具有摄像功能和AR显示功能的近眼显示器的成本、重量和体积。Further, by integrating the display component and the camera component into a camera display unit, the camera function can also be realized while the AR display is realized, and the camera view angle is consistent with the human eye view angle, that is, AR camera "what you see is what you get". At the same time, since the near-eye display does not need to be equipped with an additional camera device, it is beneficial to reduce the cost, weight and volume of the near-eye display with the camera function and AR display function.

另外，由于本发明实施例的近眼显示器没有复杂的光学透镜组和机电运动部件，因此有利于减轻近眼显示器的重量。In addition, since the near-eye display of the embodiment of the present invention does not have complex optical lens groups and electromechanical moving parts, it is beneficial to reduce the weight of the near-eye display.

其中，来自被摄对象的光线包括被摄对象反射的光线和被摄对象发出的光线。The light from the subject includes the light reflected by the subject and the light emitted by the subject.

通过在摄像显示面板的摄像部件的表面设置第二折射结构，能够筛选进入摄像部件的入射光线光路，有利于使得近眼显示器上的摄像部件具备与人眼相当的入射光线光路，进而能够对外界的被摄对象成像。By arranging the second refraction structure on the surface of the imaging component of the imaging display panel, the optical path of the incident light entering the imaging component can be screened, which is beneficial to enable the imaging component on the near-eye display to have an incident light optical path equivalent to that of the human eye, and thus be able to detect the incident light path of the outside world. The subject is imaged.

这样使得近眼显示器上的摄像部件具备与用户的眼睛相当的入射光线光路，即摄像部件的视角与用户的视角相同，可以实现用户所见与摄像部件所拍摄的图像相同。In this way, the imaging component on the near-eye display has an incident light path equivalent to that of the user's eyes, that is, the viewing angle of the imaging component is the same as the user's viewing angle, so that what the user sees is the same as the image captured by the imaging component.

需要说明的是，本发明实施例对此并不限定，第一折射结构320的入射光线的光路和第二折射结构330的出射光线的光路也可以不同，此时摄像部件的视角与用户的视角不同。It should be noted that this embodiment of the present invention is not limited to this.

Due to the reversibility of the optical path, by using two refraction structures with the same structure, the optical path of the incident light ray of one refraction structure can be made the same as the optical path of the outgoing light ray of the other refraction structure. It should be noted that this is not limited in this embodiment of the present invention, and the structures of thefirst refraction structure 320 and thesecond refraction structure 330 may also be different.

在一些实施例中，每个摄像显示单元311的显示部件3112包括多种颜色的发光单元，例如显示部件3112可以包括红色(R)发光单元、绿色(G)发光单元和蓝色(B)发光单元，如图7所示。如图8所示为每个摄像显示单元的顶视图。应理解，图8所示仅以每个摄像显示单元的顶视图为圆形为例，但本发明实施例对此并不限定。In some embodiments, thedisplay unit 3112 of eachcamera display unit 311 includes light-emitting units of multiple colors, for example, thedisplay unit 3112 may include red (R) light-emitting units, green (G) light-emitting units, and blue (B) light-emitting units unit, as shown in Figure 7.
