具体实施方式
下面详细描述本申请的实施方式，所述实施方式的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接或可以相互通讯；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
在本申请中，第一特征在第二特征之“上”可以包括第一和第二特征直接接触，也可以包括第一和第二 特征不是直接接触而是通过它们之间的另外的特征接触。
电子设备，例如手机或者平板电脑等，一般通过安装红外传感器来检测电子设备与用户之间的距离。以手机为例，在手机的上部区域设置有红外传感器。当用户进行语音通话或相关操作时，手机靠近头部，红外传感器将距离信息反馈到处理器，处理器执行相应的指令，如关闭显示屏组件的灯光等。在相关技术中，电子设备上设置红外传感器需要在机壳上开设相应的孔洞以用于发射和接收红外光信号，但随着电子设备的发展，人们对手机的外观及操作体验的要求越来越高。手机已经向全面屏方向发展，而全面屏手机在机壳与显示屏组件之间形成超窄边框，由于超窄边框的宽度过小，可能不具有足够的空间开设孔洞，即便开孔也将导致边框整体的强度降低，进而使电子设备的可靠性较低。
请参阅图1，本发明的实施方式的电子装置100可以是手机或者平板电脑等。本发明实施方式的电子装置100以手机为例进行说明，当然，电子装置100的具体形式也可以是其它，在此不做限制。
请参阅图2和图3，电子装置100包括透光显示屏13、红外传感器16和壳体20。
其中，透光显示屏13包括上表面131和下表面132，上表面131与下表面132相背设置，下表面132包括显示区1311和边框区1312，边框区1312围绕显示区1311。透光显示屏13用于透过上表面131发光显示。红外传感器16包括发射器1611和接收器1612，发射器1611用于透过边框区1312发射红外光，接收器1612用于透过显示区1311接收红外光。
发射器1611用于发射红外光，当发射的红外光在检测方向遇上障碍物时，一部分的红外光就会反射回来被接收器1612接收，经过处理器计算红外光从发射到反射回来的时间，可确定电子装置100与障碍物之间的距离并做出相应的调整。当用户在接听或者拨打电话时，电子装置100靠近头部，发射器1611发出红外光，接收器1612接收经头部反射回来的红外光，经过处理器计算该红外光从发射到反射回来的时间，发出相应指令控制屏幕关闭背景灯，当电子装置100远离头部时，处理器再次根据反馈回来的数据进行计算并发出指令，重新打开屏幕背景灯。如此，不仅防止用户的误操作，而且节省手机的电量。
壳体20用于收纳元件和组件以起到保护的作用。通过设置壳体20将元件和组件包围起来，避免了外界因素对这些元件造成直接的损坏。壳体20可以通过CNC机床加工铝合金形成，也可以采用聚碳酸酯(Polycarbonate,PC)或者PC+ABS材料注塑成型。
综上所述，本发明实施方式的电子装置100，采用透光显示屏13可以在全面屏的情况下将红外传感器16设置在透光显示屏13下方，避免了传统的开孔操作，保证电子装置100边框区1312的整体强度的可靠性，还进一步地提高电子装置的屏占比。将红光传感器16的发射器1611设置在边框区1312同时又可以避免发射器1611发出的红外光影响显示区1311的TFT的工作稳定性。
在某些实施方式中，透光显示屏13包括OLED显示屏。
具体地，有机发光二极管(Organic Light-Emitting Diode,OLED)显示屏具有良好的透光性，能够透过可见光和红外光。因此，OLED显示屏在展现内容效果的情况下也不影响红外传感器发射和接收红外光。透光显示屏13也可以采用Micro LED显示屏，Micro LED显示屏同样具有对可见光和红外光良好的透光率。当然，这些显示屏仅作为示例性的而本发明的实施例并不限于此。
请参阅图4，在某些实施方式中，电子装置100还包括透光触控面板12和透光盖板11。透光盖板 11形成于透光触控面板12上，透光触控面板12设置在透光显示屏13上，透光显示屏13的上表面131朝向透光触控面板12，透光触控面板12和透光盖板11对可见光的透光率和红外光的透光率均大于90％。
具体地，透光触控面板12主要用于接收用户在触碰透光触控面板12时产生的输入信号并传送到电路板进行数据处理，从而获得用户触碰透光触控面板12的具体位置。其中，可以采用In-Cell或者On-Cell贴合技术将透光触控面板12与透光显示屏13进行贴合，能够有效地减轻显示屏的重量和减少显示屏的整体厚度。另外，将透光盖板11设置在透光触控面板12上，能够有效地保护透光触控面板12及其内部结构，避免了外界作用力对透光触控面板12及透光显示屏13的损坏。透光盖板11和透光触控面板12对可见光和红外光的透光率均大于90％，不仅有利于透光显示屏13较好地展现内容效果，而且还有利于设置在透光显示屏13下的红外传感器16稳定地发射和接收红外光，保证了红外传感器16的正常工作。
请结合参阅图3，在某些实施方式中，透光显示屏13用于透过显示区1311发光显示，显示区1311与透光盖板11的面积之比大于90％。
具体地，通过设置显示区1311和透光盖板11的比例，使透光显示屏13经过透光盖板11贴合后，显示区1311能够以较大的尺寸面积来展现内容效果，不仅提升了良好的用户体验，而且还有效地增大了电子装置100的屏占比。边框区1312还能用于遮挡位于透光显示屏13下的其它元件和金属线路，使产品的外观保持一致性。边框区1312可以通过印刷油墨的方式来增强透光显示屏13的光学密度，在保证遮光作用的同时也营造了良好的视觉效果。
请参阅图5，在某些实施方式中，电子装置100还包括第一涂布层14，第一涂布层14涂布于下表面132并覆盖发射器1611。
具体地，在进行工艺装配的过程中发射器1611的安装通常需要预留装配间隙，导致发射器1611与其他元件之间出现缝隙，使可见光从缝隙里进入，出现漏光现象。因此，在发射器1611和透光显示屏13层叠的方向上，第一涂布层14在下表面132的正投影的面积覆盖发射器1611在下表面132的正投影的面积，能够在不影响发射器1611正常工作的情况下，使第一涂布层14充分遮挡发射器1611，实现从外部观看电子装置100时，达到发射器1611不可见的效果。
在某些实施方式中，第一涂布层14用于透过红外光和拦截可见光，发射器1611用于透过第一涂布层14和边框区1312发射红外光。
具体地，第一涂布层14透过红外光，能够使发射器1611在向外发射红外光进行检测时，红外光透过第一涂布层14的强度衰减得较小，或者说衰减的程度并不对检测过程造成影响，从而保证了发射器1611的正常工作。第一涂布层14拦截可见光，使可见光不能通过第一涂布层16，从视觉上遮挡发射器1611，实现从外部观看电子装置100时，达到发射器1611不可见的效果。
在某些实施方式中，红外传感器16包括接近传感器，接近传感器包括信号发射器1和信号接收器，信号发射器用于透过第一涂布层1311和边框区1312发射红外光，信号接收器用于接收经物体反射的红外光以检测所述物体与电子装置100的距离。
具体地，当用户在接听或者拨打电话时，电子装置100靠近头部，信号发射器发出红外光，信号接收器接收反射回来的红外光，处理器计算红外光从发射到反射回来的时间，发出相应指令控制屏幕关闭 背景灯，当电子装置100远离头部时，处理器再次根据反馈回来的数据进行计算并发出指令，重新打开屏幕背景灯。如此，不仅防止用户的误操作，而且节省手机的电量。
在某些实施方式中，第一涂布层14包括IR油墨，IR油墨对红外光的透光率大于85％，对可见光的透光率小于6％，IR油墨可透过的红外光的波长为850nm-940nm。
具体地，由于IR油墨具有对可见光低透光率的特性，所以从外部观看电子装置100时，基于人眼的视觉观察不到设置在第一涂布层14下的发射器1611。同时，由于IR油墨兼具对红外光高透光率的特性，能够使发射器1611稳定地发射红外光，保证了发射器1611的正常工作。
请参阅图6至图9C，在某些实施方式中，发射器1611和接收器1612为分体结构。
具体地，由于发射器1611和接收器1612为分体结构，所以在排布位置时可以选择紧凑排布，也可以选择分散排布，可以灵活地将接收器1612设置在诸如低频显示的区域等对显示像素影响不大的位置。如此，不仅有利于电子装置100充分分配各元件的空间位置和应用多种形状的发射器1611和接收器1612，而且还有利于发射器1611和接收器1612为电子装置100中的其他元件提供可能的位置并降低对电子装置100显示像素的影响。当发射器1611和接收器1612分散排布时，可以在边框区1312设置一个发射器1611，在显示区1311设置一个接收器1612。也可以在边框区1312设置一个发射器1611，在显示区1311设置多个接收器1612。也可以在边框区1312两侧各设置一个发射器1611，在显示区1311两侧对应各设置一个接收器1612。
请参阅图5，在某些实施方式中，发射器1611和接收器1612为一体结构。
具体地，发射器1611和接收器1612为一体结构，一体结构使得元件整体结构紧凑，使得显示屏下元件布局合理，减少线路工艺流程以及布线空间，提高产品的生产效率，降低生产成本，元件布局规整方便检修及维护。
在一些示例中，该一体结构还可包括有环境光传感器，更进一步提高元件的集成度。
请参阅图10A或者图10B，在某些实施方式中，电子装置100还包括涂布于下表面132且覆盖接收器1612的第二涂布层15，第二涂布层15用于透过红外光和拦截可见光，接收器1612用于透过显示区1311和第二涂布层15接收红外光。
具体地，在进行工艺装配的过程中接收器1612的安装通常需要预留装配间隙，导致接收器1612与其他元件之间出现缝隙，使可见光从缝隙里进入，出现漏光现象。因此，在接收器1612和透光显示屏13层叠的方向上，第二涂布层15在下表面132的正投影的面积覆盖接收器1612在下表面132的正投影的面积，能够在不影响接收器1612正常工作的情况下，使第二涂布层15充分遮挡接收器1612，实现从外部观看电子装置100时，达到接收器1612不可见的效果。第二涂布层15也可以采用IR油墨，由于IR油墨具有对可见光低透光率的特性，所以从外部观看电子装置100时，基于人眼的视觉不能够察觉到设置在第二涂布层15下的接收器1612。同时，由于IR油墨兼具对红外光高透光率的特性，能够使接收器1612稳定地接收红外光，保证了接收器1612的正常工作。
请参阅图11A或者图11B，在某些实施方式中，电子装置100还包括覆盖下表面132且避让接收器1612的缓冲层17。
具体地，缓冲层17用于减缓冲击力和防震以保护透光触控面板12和透光显示屏13及其内部结构，避免显示屏因受到外界的冲击作用而损坏。缓冲层17可以由泡棉或者泡沫塑料或者橡胶或者其他软质材料制成。当然，这些缓冲材料仅作为示例性的而本发明的实施例并不限于此。此外，在设置缓冲层17的过程中避让接收器1612是为了防止缓冲层17阻截接收器1612接收信号，以免接收器1612在接收红外光的过程中受到影响。
请参阅图12A或者图12B，进一步地，在这样的实施方式中，电子装置100还包括覆盖缓冲层17且避让接收器1612的金属片18。
具体地，金属片18用于屏蔽电磁干扰及接地，具有扩散温升的作用。金属片18可以采用铜箔、铝箔等金属材料裁剪而成。当然，这些金属材料仅作为示例性的而本发明的实施例并不限于此。此外，在设置金属片18的过程中避让接收器1612是为了防止金属片18阻截接收器1612接收信号，以免接收器1612在接收红外光的过程中受到影响。

S302，提供一红外传感器16，红外传感器16包括用于透过边框区1312发射红外光的发射器1611和透过显示区1311接收红外光的接收器1612。
具体地，电子装置100采用透光显示屏13，可以在全面屏的情况下将红外传感器16设置在透光显示屏13下方，并且将红光传感器16的发射器1611设置在边框区1312可以避免发射器1611发出的红外光影响显示区1311的TFT的工作稳定性，从而使得透光显示屏13和红外传感器16可以在互不干涉的情况下实现各自功能。透光显示屏13可以是有机发光二极管(Organic Light-Emitting Diode,OLED)显示屏，OLED显示屏具有良好的透光性，能够通过可见光和红外光。因此，OLED显示屏在展现内容效果的情况下也不影响红外传感器发射和接收红外光。透光显示屏13也可以采用Micro LED显示屏，Micro LED显示屏同样具有对可见光和红外光良好的透光率。当然，这些显示屏仅作为示例性的而本发明的实施例并不限于此。此外，透光显示屏13的上表面131一方面用于透过可见光展现内容效果，另一方面则用于透过红外光使红外传感器16正常发射和接收红外光。
