具体实施方式
为使本公开的技术方案和优点更加清楚明白，下文中将结合附图对本公开的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在计算机***中由诸如一组计算机可执行指令执行。并且，虽然在流程图中示出了各步骤的顺序， 但是在某些情况下，可以以不同于所示出的顺序执行各步骤。
由于相关技术中执行空间定位或3D位置检测的仪器或设备需要配置专门的硬件设施，并且要额外占用一定的空间，使这类设备的应用范围受物理位置的影响较大，且实用性较差。随着显示技术的发展，显示装置作为人们日常生活中不可缺少的工具和娱乐设施，在家庭和公共场所的各个角落随处可见。基于显示装置的广泛应用程度，本公开实施例提出一种在显示装置中集成空间定位能力的方案。
本公开提供的以下几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图1为本公开实施例提供的一种阵列基板的结构示意图。本实施例提供的阵列基板100可用于形成显示面板。该阵列基板100可以包括衬底基板110、设置于衬底基板110一侧的像素层120、与像素层120具有相同出光方向的光源结构130。
光源结构130可用于发出准直非可见光。
像素层120可包括子像素121和设置于各子像素121之间的至少一个感应像素122。本公开各实施例中的子像素121以红、绿、蓝(Red、Green、Blue，简称为RGB)子像素为例予以示出，感应像素122表示为S。
感应像素122用于接收光源结构130发出的准直非可见光经待定位物体反射的反射光，以确定待定位物体的位置。
图1所示为阵列基板100的沿第一方向截取的剖视图，且图1中示出了待定位物体200，该待定位物体200位于阵列基板100的出光侧。本公开实施例中的光源结构130可以设置于衬底基板110的远离像素层120的一侧，该光源结构130可发出准直非可见光。准直光具有较强的方向性，可以实现精度较高的测量。非可见光不会影响阵列基板100用于显示时的正常显示。也就是说，阵列基板100可通过子像素121实现显示功能，例如子像素121可以为发光子像素121(发出可见光)，光源结构130为实现空间定位而设置，该光源结构130所发出的光不能影响阵列基板100用于显示时的正常显示，因此，可以配置光源结构130发出非可见光，例如可以发出对人体没有伤害的 红外光。而且，光源结构130的出光方向与像素层120的出光方向相同。可以理解的是，通常的阵列基板100从一侧发光以供用户观看，也就是说，光源结构130的出光方向与像素层120的出光方向可均指向观看用户。
在本公开实施例中，阵列基板100的像素层120中不仅包括用于显示的子像素121，在子像素121之间还设置有感应像素122，感应像素122作为与光源结构130(发射端)相对应的接收端，可以接收由光源结构130发出的、且照射到待定位物体200(例如观看用户)上被反射回的反射光，该反射光可以为光源结构130发出的准直非可见光在待定位物体200上发生漫反射后返回的光。
本公开实施例采用发出准直非可见光的光源结构130和接收该准直非可见光经待定位物体反射的反射光的感应像素122，光源结构130发出的准直非可见光经待定位物体200反射后到达感应像素122的光路即准直非可见光的往返光路。将本公开实施例提供的阵列基板100应用于显示装置中时，显示装置中配置的处理器，例如集成电路(Integrated Circuit，简称为IC)芯片可以通过测量上述往返光路来计算待定位物体200到显示装置的距离，例如可测量发出光和接收光的时间，可以理解的是，处理器可与光源结构130连接，从而可以获知发出准直非可见光的发射时间，处理器可与感应像素122相连接，从而感应像素122在接收到反射光时，可以将接收时间反馈给处理器，处理器可以根据已知的数据信息计算待定位物体200到显示装置的距离。
实际应用中，待定位物体200可能是一体积较大的物体，可设置多个感应像素122来进行空间定位，该情况下，多个感应像素122接收到光源结构130发出且由待定位物体200反射回的反射光，处理器可根据这些感应像素122接收到的反射光所经过的往返光路来计算出待定位物体200的空间位置。
在本公开实施例中，光源结构130和像素层120可以设置于衬底基板110的不同侧，图1以光源结构130和像素层120分别设置于衬底基板110的不同侧为例予以示出，然而，光源结构130和像素层 120还可以设置于衬底基板110的同侧。本公开实施例的阵列基板例如可用于形成液晶显示器(Liquid Crystal Display，简称为LCD)、顶发光型有机电致发光显示器(Organic Electroluminance Display，简称为OLED)、或底发光型OLED等。在一些实施方式中，阵列基板100中还可包括控制子像素121开关的薄膜晶体管(Thin Film Transistor，简称为TFT)、电极层140、封装层150等。
与相关技术中用于实现空间定位的设备相比，本公开实施例提供的阵列基板100中集成有用于实现空间定位功能的硬件结构，且用于实现空间定位功能的硬件结构在执行空间定位时不会影响阵列基板100用于显示时的正常显示，其空间定位功能是独立运行的。将本公开实施例提供的阵列基板100应用于3D显示交互场景中，例如体感游戏等场景，无需额外设置专门用于空间定位的硬件设施，一方面节省了额外配置硬件设施的硬件成本，另一方面可以尽可能降低3D显示交互受空间范围的限制，提高了阵列基板100的实用性。
本公开实施例提供的阵列基板100通过在像素层120的子像素121之间设置感应像素122、以及设置与像素层120具有相同出光方向的可以发出准直非可见光的光源结构130，感应像素122可以接收到光源结构130发出的准直非可见光经待定位物体200反射的反射光，将该阵列基板100应用于显示装置中时，显示装置中配置的处理器可以根据光源结构130发出的准直非可见光和感应像素122接收的反射光的相关数据信息，计算待定位物体200到显示装置的距离，即实现了空间定位。本公开实施例提供的阵列基板100通过对传统阵列基板的结构进行合理的改造，在阵列基板100中集成了用于实现空间定位的结构和功能，因此将该阵列基板100应用于显示装置中时，在阵列基板100用于正常显示的同时可以配合显示装置中的处理器进行空间定位，并且该阵列基板100的结构简单，易于实现，用于空间定位的硬件结构不需要额外占用其它空间。另外，非可见光可以采用对人体无伤害的红外光，有利于用户与该阵列基板100所属的显示装置之间进行3D显示交互。
在本公开实施例中，在像素层120中设置多个感应像素122的 情况下，像素层120中感应像素122的密度可以根据空间定位的精度进行配置，例如每个像素(例如包括GRB三个子像素121)可对应一个感应像素122，本公开各实施例的附图均以该配置为例予以示出。另外，每个像素也可对应2个感应像素122，或者，多个像素可对应一个感应像素122，或者，一个或多个子像素121可对应一个感应像素122。作为示例，相邻感应像素122之间可设置有一个或多个子像素121。本公开实施例中的感应像素122例如可以为光敏传感器，并且本公开实施例不限制感应像素122的密度和数量，只要可以实现要求精度的空间定位即可。
图2为本公开实施例提供的又一种阵列基板的结构示意图。在图1所示阵列基板100的结构基础上，本实施例提供的阵列基板100中，像素层120包括设置于各像素之间的阵列排布的感应像素122，光源结构130可以包括阵列排布的、且与感应像素122一一对应的光源131、以及设置于光源131的出光侧的准直光学层132，即所述准直光学层132设置在光源131与像素层120之间。
光源131用于发出非可见光。本公开实施例中的光源131例如可以是红外OLED阵列、或者是微型(Mirco)OLED阵列。
准直光学层132用于将入射到准直光学层132的非可见光转换为准直非可见光。该准直光学层132例如可以采用准直厚孔结构实现，也可采用其它结构实现，上述阵列排布的光源131设置在准直光学层132的远离衬底基板110的一侧。
在本公开实施例中，采用阵列排布的光源131和准直光学层132的组合结构实现用于发出准直非可见光的光源结构130，由于一般的光源131为点光源，通过在光源131的出光侧设置准直光学层132，可以将入射到准直光学层132的光转换为准直光，从而实现光源结构130发出准直非可见光的目的。另外，光源131与像素层120中的感应像素122可以设置为一一对应的关系，即每个感应像素122主要用于对与其对应的光源131发出的经准直的非可见光的反射光进行接收，这样，可以提高空间定位的精度。
基于本公开上述各实施例提供的阵列基板100，本公开实施例还提供一种显示装置，该显示装置包括本公开上述任一实施例中的阵列基板100、以及分别与阵列基板100中的光源结构130和感应像素122相连接的处理模块。
本公开实施例中的处理模块用于根据光源结构130发出的准直非可见光和感应像素122接收的该准直非可见光经待定位物体200反射的反射光的相关数据信息，计算待定位物体200到显示装置的距离。
在本公开实施例中，处理模块通常以硬件结合软件的方式实现，该处理模块可以是显示装置中的处理器，例如IC芯片，该处理器中配置有功能软件，可以实现处理模块要实现的功能。在具体实现中，处理模块可以根据光源结构130发出的准直非可见光经待定位物体200反射后到达感应像素122的往返光路来计算待定位物体200到显示装置的距离，例如可记录光源结构130发出光和感应像素122接收光的时间，可以理解的是，处理模块可与光源结构130连接以获知光源结构130发出准直非可见光的发射时间，处理模块可与感应像素122相连接，从而感应像素122在接收到反射光时，可以将接收时间反馈给处理模块，处理模块可以根据已知的数据信息计算待定位物体200到该显示装置的距离。
实际应用中，待定位物体200可能是一体积较大的物体，在设置多个感应像素122来进行空间定位的情况下，多个感应像素122接收到光源结构130发出且由待定位物体200反射回的反射光，处理模块可根据这些感应像素122接收到的反射光所经过的往返光路来计算出待定位物体200的空间位置。
需要说明的是，本公开实施例的显示装置中阵列基板100的硬件结构可以参照上述结合图1或图2所示的实施例，并且光源结构130和像素层120可以设置于衬底基板110的不同侧或相同侧，具体设置方式可与上述实施例相同，另外，本公开实施例的显示装置相比于相关技术的优势和有益效果也与上述实施例相同，故在此不再赘述。
本公开提供的显示装置中，基于上述实施例中阵列基板100的 结构特征，光源结构130可以发出准直非可见光，感应像素122可以接收到该准直非可见光经待定位物体200反射的反射光，显示装置中与光源结构130和感应像素122相连接的处理模块可以根据光源结构130发出准直非可见光和感应像素122接收反射光的相关数据信息，计算待定位物体200到显示装置的距离，即实现了空间定位。本公开提供的显示装置通过对传统显示装置的结构进行合理的改造，在显示装置中集成了用于实现空间定位的结构和功能，使得显示装置在正常显示的同时可以进行空间定位，并且该显示装置的结构简单，易于实现，用于空间定位的硬件结构不需要额外占用其它空间。另外，非可见光可以采用对人体无伤害的红外光，有利于用户与显示装置之间进行3D显示交互。
在一些实施方式中，本公开实施例提供的显示装置中，其阵列基板100的光源结构130包括光源131和准直光学层132，处理模块分别与光源结构130中的每个光源131相连接，处理模块还用于对每个光源131发出的非可见光进行调制，使得光源结构130在第一方向上的每个光源131发出的非可见光的频率不同，感应像素122还用于对接收到的反射光进行解调，以得到光电信息，并且感应像素122的解调频率与对应光源131的调制频率相同。
本公开实施例中，处理模块对阵列基板100的第一方向(例如为X轴方向)上的每个光源131发出的非可见光进行调制，使得第一方向上的各光源131发出的非可见光的频率不同。举例来说，图3所示为本公开实施例提供的显示装置中的阵列光源的示意图，光源结构130中的光源131设置为n术m阵列排布的形式，沿第一方向的每排(例如每行)包括n个光源131，沿第二方向(该第二方向与第一方向垂直，例如为Y轴方向)的每排(例如每列)包括m个光源131，图3中阵列排布的光源131以Lij标识，Lij代表第一方向上第i个、第二方向上第j个光源131，沿第一方向的每排的n个光源131发出的非可见光经过处理模块的调制后，出射光的频率分别为F1、F2、…、Fi、…、Fn。相应地，图4所示为本公开实施例提供的显示装置中的像素层的示意图，图4以像素层120中每个像素(包括RGB三个发光 子像素121)对应一个感应像素122为例予以示出，该像素层120中感应像素122的设置形式与光源131的相同，同样为n*m阵列排布的形式，图4中阵列排布的感应像素122以Sij标识，Sij代表第一方向上第i个、第二方向上第j个感应像素122，即沿第一方向的每排的n个感应像素122的解调频率分别为F1、F2、…、Fi、…、Fn。
基于上述图3和图4所示的光源131和感应像素122一一对应的结构特征，本公开实施例中的光源131发出非可见光后，经待定位物体200反射的反射光被相应的感应像素122接收到，由于处理模块对每个光源131发出的光进行了调制，且上述已经说明沿第一方向的每排的n个光源131的调制频率不同，以沿第一方向的某一排的第i个光源131为例予以说明，该光源131的调制频率为Fi，与该光源131对应的感应像素122以相同的频率(Fi)对接收到的反射光进行解调，恢复得到Fi的光电信息。因此，即使沿第一方向的某一排的n个感应像素122同时执行解调，由于其解调频率各不相同，分别为上述F1、F2、…、Fi、…、Fn，相邻感应像素122之间互不干扰。
在本公开实施例中，光源131可以发出脉冲非可见光。
处理模块可用于控制感应像素122对接收到的反射光进行第一次解调和第二次解调，且第一次解调和第二次解调相差1/4个脉冲周期，该情况下，可根据以下(1)式计算出待定位物体200到显示装置的距离。
2S＝1/4Fi*c*A/(A+B)     (1)
上述(1)式中，S为待定位物体200到显示装置的距离，Fi为第一方向上第i个光源131发出的非可见光的调制频率，A为感应像素122进行第一次解调得到的光电信息，B为感应像素122进行第二次解调得到的光电信息，c为脉冲非可见光的光速。需要说明的是，上述(1)式的计算中，A和B为同一个感应像素122进行第一次解调和第二次解调分别得到的光电信息。
在本公开实施例中，光源131例如发出脉冲红外光，该脉冲红外光通过准直光学层132准直后照射到待定位物体200，然后产生漫反射，反射光被相应的感应像素122接收到，上述已经说明处理模块 对某个光源131发出的光的调制频率与对应感应像素122执行解调的解调频率相同，即感应像素122可以解调其接收到的反射光来得到相应频率的光电信息。
在实际应用中，本公开实施例中的感应像素122可以采用多相位采样的方式，通过快速采样得到两次采样之间的差值，从而计算待定位物体200到显示装置的距离，例如，两次采样(对应于第一次解调和第二次解调)相差1/4个脉冲周期，图5所示为本公开实施例提供的显示装置中的光路的时序图，图5中示出了光源131发出的脉冲非可见光的脉冲周期和时序、反射光所经历的往返时间、以及每次测量中两次采样(解调)的时间段，可以看出，两次采样相差1/4个脉冲周期。本公开实施例可以通过感应像素122内部的多相位采样机制，获得不同相位下特定频率(例如Fi)的光电信息，从而得到相应光源131(Fi频率对应的光源)与待定位物体200的距离。
需要说明的是，上述采样方式和图5所示时序图仅用于本公开实施例的示意性说明，本公开实施例不限制采样形式仅为两次采样，也不限制两次采样之间必须相差1/4个脉冲周期，可以根据实际情况配置感应像素122的采样次数、以及两次采样之间相差的时间。
在本公开实施例中，处理模块还可用于依次点亮沿第一方向的每排光源。图6所示为本公开实施例提供的一种显示装置的结构示意图。本公开实施例提供的显示装置还可以包括设置于非显示区、且与每个光源131相连接的移位寄存器160，该移位寄存器160用于依次点亮沿第一方向的每排光源。图6所示显示装置仅示出阵列排布的光源131和移位寄存器160，图6以图3所示阵列光源131的结构为基础予以示出，且图6以移位寄存器160与沿第一方向的m排光源131连接的方式表示移位寄存器160与m排光源中每个光源131的连接关系。
在本公开实施例中，可以在阵列基板100的显示区周边的非显示区设置移位寄存器160，且该移位寄存器160分别与每个光源131相连接，另外，上述实施例中已经说明处理模块可分别与每个光源131相连接。本公开实施例采用移位寄存器160(或处理模块)控制 光源结构130中的光源131按照一定的次序点亮，例如逐行点亮、或逐列点亮，同一时间段在第一方向上点亮的光源的调制频率不同。
对于本公开实施例的依次点亮沿第一方向的每排光源方式，可以采用以下两种方式中的任一种接通感应像素122。
第一种方式，本公开实施例中的处理模块可用于依次接通沿第一方向的每排感应像素122，使得每个感应像素122对与其对应的光源131发出的经待定位物体200反射的反射光进行接收和解调。
基于本公开上述实施例中的调制和解调的实现方式，光源结构130中的沿第一方向的各排(行或列)光源131逐排(行或列)点亮，且同时点亮的每排光源131的调制频率不同，因此，像素层120中感应像素122的接通形式同样可以是沿第一方向的各排感应像素122逐排接通，以接收反射光并进行解调，即在点亮每排光源131时接通对应排的感应像素122。举例来说，沿第一方向的每排的n个光源中每个光源131的出射光的调制频率不同，例如分别为F1、F2、…、Fi、…、Fn，与该n个光源131对应的n个感应像素122的解调频率也不相同，分别为F1、F2、…、Fi、…、Fn。
第二种方式，本公开实施例中的处理模块可用于同时接通沿第二方向的每排感应像素122，与每个点亮光源131对应的感应像素122和其沿第二方向的同一排的感应像素122同时对该点亮光源131发出的经待定位物体200反射的反射光进行接收和解调，然后可根据以下(2)式计算出待定位物体200到显示装置的距离。
S＝(Si+a1*Si1+a2*Si2+……+ax*Six)/(1+x)   (2)
上述(2)式中，S为待定位物体200到显示装置的距离，Si为通过第一方向上的第i个点亮光源131的对应感应像素122计算得到的距离，Si1到Six为通过上述对应感应像素122的沿第二方向的同一排的感应像素122计算得到的距离，a1到ax分别为Si1到Six向Si映射的系数，第二方向与第一方向垂直，且沿第二方向的每排的各光源131发出的非可见光的频率相同，x为小于m-1的正整数，m为沿第二方向的每排感应像素122的个数。
图7所示为采用本公开实施例提供的显示装置进行空间定位的 实现原理示意图，图7中仅示出了沿第二方向截取的阵列基板100的剖视图。参考图3和图4所示的光源131和感应像素122的结构，本公开实施例中，假设光源Lij(表示该光源131位于第一方向上的第i个位置、第二方向上的第j个位置)所在的沿第一方向的一排光源131点亮，光源Lij发出的经待定位物体200反射后的非可见光可以被与其对应的感应像素Sij(表示该感应像素122位于第一方向上的第i个位置、第二方向的第j个位置)接收和解调，另外，与感应像素Sij在沿第二方向的同一排的感应像素122(例如包括Si(j-1)、Si(j+1)、Si(j-2)、Si(j+2)等)的解调频率与感应像素Sij的解调频率相同，均为Fi，因此这些与感应像素Sij在沿第二方向的同一排的感应像素122也可以接收和解调光源Lij发出的经待定位物体200反射后的非可见光，然后可通过计算将这些与感应像素Sij在沿第二方向的同一排的感应像素122计算出的距离映射到光源Lij所在的沿第一方向的排(行或列)，再对得到的距离计算平均值得到最终的距离值。图7所示实施例提供的方式有利于消除由于噪声带来的距离值的抖动。
基于本公开上述各实施例提供的显示装置，本公开实施例还提供一种显示装置的空间定位方法，该显示装置的空间定位方法采用本公开上述任一实施例提供的显示装置执行。
图8所示为本公开实施例提供的一种显示装置的空间定位方法的流程图。本公开实施例提供的空间定位方法由显示装置执行，该方法可以包括如下步骤S210和S220。
S210，采集光源结构发出的准直非可见光和感应像素接收的该准直非可见光经待定位物体反射的反射光的相关数据信息。
S220，根据采集的数据信息，计算待定位物体到显示装置的距离。
在本公开实施例中，用于执行空间定位方法的显示装置的阵列基板可以包括衬底基板、设置于衬底基板一侧且排布于像素层中的至少一个感应像素、与像素层具有相同出光方向的光源结构。上述结构 为显示装置执行空间定位的硬件基础，本公开实施例中的显示装置还包括用于执行程序处理的处理模块，该处理模块分别与光源结构和感应像素相连接，该显示装置的硬件结构和各结构实现的功能可以参照本公开的图1和图2所示实施例中的阵列基板100以及图3到图7所示实施例中的显示装置的描述，故在此不再赘述。
本公开实施例中，光源结构可以发出准直非可见光，光源结构发出的准直非可见光经待定位物体反射后到达感应像素的光路即光源结构发出的准直非可见光的往返光路。本公开实施例中的步骤由处理模块执行，即处理模块可以通过采集光源结构发出准直非可见光和感应像素接收该准直非可见光经待定位物体反射的反射光的相关数据信息，根据光源结构发出的准直非可见光的往返光路来计算待定位物体到显示装置的距离，例如记录光源结构发出准直非可见光和感应像素接收该准直非可见光经待定位物体反射的反射光的时间，可以理解的是，处理模块可与光源结构连接以获知光源结构发出准直非可见光的发射时间，处理模块可与感应像素相连接，从而感应像素接收到反射光时，可以将接收时间反馈给处理模块，处理模块可以根据已知的数据信息计算待定位物体到显示装置的距离。
实际应用中，待定位物体可能是一体积较大的物体，显示装置可设置多个感应像素来执行空间定位，该情况下，多个感应像素接收到光源结构发出且由待定位物体反射回的反射光，处理模块可根据这些感应像素接收到的反射光所经过的往返光路来计算出待定位物体的空间位置。
与相关技术中用于实现空间定位的设备相比，本公开实施例提供的空间定位方法由集成有用于实现空间定位功能的显示装置执行，且显示装置中用于实现空间定位功能的硬件结构在执行空间定位时不会影响显示装置的正常显示，其空间定位功能是独立运行的。将本公开实施例提供的显示装置的空间定位方法应用于3D显示交互场景中，例如体感游戏等场景，无需额外设置专门用于空间定位的硬件设施，一方面节省了额外配置硬件设施的硬件成本，另一方面可以尽可能降低3D显示交互受空间范围的限制，提高了该方法的实用性。
本公开提供的显示装置的空间定位方法基于本公开上述实施例中显示装置的硬件配置，通过采集光源结构发出准直非可见光和感应像素接收该准直非可见光经待定位物体反射的反射光的相关数据信息，然后根据这些数据信息计算出待定位物体到显示装置的距离，即实现了空间定位。本公开提供的显示装置的空间定位方法通过对传统显示装置的结构进行合理的改造，在显示装置中集成了实现空间定位的结构和功能，使得显示装置在正常显示的同时可以进行空间定位，并且该显示装置的结构简单，易于实现，用于空间定位的硬件结构不需要额外占用其它空间。另外，非可见光可以采用对人体无伤害的红外光，有利于用户与显示装置之间进行3D显示交互。
图9为本公开实施例提供的另一种显示装置的空间定位方法的流程图。本公开实施例中，显示装置的像素层可包括阵列排布的感应像素，显示装置的光源结构可以包括阵列排布的且与感应像素一一对应的光源、以及设置于光源的出光侧的准直光学层，采用阵列排布的光源和准直光学层的组合结构实现出射准直非可见光。在图8所示实施例的基础上，本公开实施例提供的方法在S210之前还可以包括步骤S200。
S200，对每个光源发出的非可见光进行调制，使得光源结构的沿第一方向的各个光源发出的非可见光的频率不同。
本公开实施例中，由于处理模块可以对光源发出的非可见光进行调制，相应地，感应像素对接收到的反射光进行解调，得到光电信息，并且感应像素的解调频率与对应光源的调制频率相同，因此，处理模块采集到的感应像素接收的反射光的相关数据信息包括：感应像素对接收到的反射光进行解调得到的光电信息。需要说明的是，阵列排布的光源和阵列排布的感应像素的结构可以参照上述实施例中的图3和图4所示，处理模块对光源发出的非可见光进行调制的频率以及感应像素进行解调的频率的配置方式在图3和图4所示具体示例中已经详细描述，故在此不再赘述。
在本公开实施例中，光源可以发出脉冲非可见光。该情况下，本公开实施例提供的方法还可以包括步骤S201。
S201，控制感应像素对接收到经待定位物体反射的反射光进行第一次解调和第二次解调，以计算待定位物体到显示装置的距离。第一次解调和第二次解调可相差1/4个脉冲周期。
可根据以下(1)式计算出待定位物体到显示装置的距离。
2S＝1/4Fi*c*A/(A+B)       (1)
上述(1)式中，S为物体200到显示装置的距离，Fi为第一方向上第i个光源131发出的非可见光的调制频率，A为感应像素122进行第一次解调得到的光电信息，B为感应像素进行第二次解调得到的光电信息，c为脉冲非可见光的光速。需要说明的是，上述式(1)的计算中，A和B为同一个感应像素进行第一次解调和第二次解调分别得到的光电信息。
本公开实施例中，感应像素进行两次采样(对应于第一次解调和第二次解调)的时序图可以参照图5所示，两次采样和计算距离的实现方式在上述实施例中已经详细描述，故在此不再赘述。
图10为本公开实施例提供的又一种显示装置的空间定位方法的流程图。在图8所示实施例的基础上，本公开实施例提供的方法在S210之前还可以包括步骤S202。
S202，依次点亮沿第一方向的每排光源。
在本公开实施例中，可以在阵列基板的显示区周边的非显示区设置移位寄存器，且该移位寄存器分别与每个光源相连接，另外，上述实施例中已经说明处理模块分别与每个光源相连接。本公开实施例中的S202可以由处理模块或移位寄存器执行，即可以采用移位寄存器(或处理模块)控制光源结构中的光源按照一定的次序点亮，例如逐行点亮、或逐列点亮，同一时间段点亮的沿第一方向的一排光源的调制频率不同。
在本公开实施例的一些实施方式中，步骤S202之后还可以包括步骤S203。
S203，依次接通沿第一方向的每排感应像素，使得每个感应像素对对应光源发出的经待定位物体反射的反射光进行接收和解调。
在本公开实施例的一些实施方式中，步骤S202之后还可以包括 步骤S204。
S204，同时接通像素层中沿第二方向的每排感应像素，使得与点亮光源对应的感应像素和其沿第二方向的同一排的感应像素同时对该点亮光源发出的非可见光经待定位物体反射的反射光进行接收和解调，然后可根据以下(2)式计算待定位物体到显示装置的距离。
S＝(Si+a1*Si1+a2*Si2+……+ax*Six)/(1+x)   (2)
上述(2)式中，S为待定位物体到显示装置的距离，Si为通过第一方向上的第i个点亮光源的对应感应像素计算得到的距离，Si1到Six为通过上述对应感应像素的沿第二方向的同一排的感应像素计算得到的距离，a1到ax分别为Si1到Six向Si映射的系数，第二方向与第一方向垂直，且沿第二方向的每排的各光源发出的非可见光的频率相同，x为小于m-1的正整数，m为沿第二方向的每排感应像素的个数。
需要说明的是，S203和S204的实现方式在上述实施例中已经详细描述，故在此不再赘述。另外，图10所示实施例中S203和S204为可选的，可择一执行。
图11为本公开实施例提供的一种计算机设备的结构示意图。本公开实施例提供的计算机设备30可以包括存储器31和处理器32。
存储器31用于保存可执行指令。
