前述的摄像头120、指纹传感器130、光学体征识别传感器140、距离传感器150、接近光传感器160以及环境光传感器170等在实现其相应的功能时，需要和用户手指直接接触，或者不被其他物体遮挡，这就要求在显示面板上 为暴露这些感应器而设置的窗口更多或更大。
然而，在当前显示装置的发展趋势中，全面屏显示越来越流行，这要求显示面板的显示区的面积越来越大、非显示区的面积越来越小。而前述多个感应器一般都设置在非显示区内。
在此基础上，如图2A和图2B所示，本公开一些实施例的显示装置100还包括壳体101，显示面板110位于壳体101内，壳体101支撑并保护显示面板110。该显示装置100还包括支架102，支架102包括轴1021，支架102位于壳体101和显示面板110之间，并被配置为固定和支撑前述多个感应器。例如，支架102的轴1021一端固定在壳体101中，另一端通过轴承设置在支架102中，使得支架102能够相对于轴1021转动。在本公开一些实施例中，前述多个感应器包括以下组合中的至少两种：摄像头120、指纹传感器130、光学体征识别传感器140、距离传感器150、接近光传感器160、或环境光传感器170等。作为示例，图2A和图2B仅示出了指纹传感器130和光学体征识别传感器140。
显示面板110包括窗口111，该窗口111的尺寸小于暴露所述多个感应器所需的尺寸。例如，窗口111的尺寸仅可以暴露一个感应器。再例如，当所述多个感应器的数量多于两个时，窗口111的尺寸仅可以暴露一个或两个感应器。再例如，当所述多个感应器的数量多于三个时，窗口111的尺寸仅可以暴露一个或两个或三个感应器。这样，当用户需要使用某个感应器时，可以驱动支架102转动，以使该感应器通过窗口111暴露出来。为此，显示装置100还包括驱动器103，该驱动器103与支架102连接，以驱动支架102转动。
在一些实施例中，如图2A所示，窗口111包括通过在显示面板110上去除材料而形成的缺口1111。在一些实施例中，如图2B所示，窗口111包括通过在显示面板110上去除材料而形成的缺口1111、以及覆盖该缺口的透明或半透明保护层1112，该透明或半透明保护层1112可以由塑料、树脂、或者玻璃制成。该透明或者半透明保护层可以保护前述的多个感应器不直接接触氧气和水汽，以避免氧气或水汽影响多个感应器的寿命。
需要说明的是，窗口111不局限于设置在显示面板110上，而是还可以位于壳体101上。
本公开一些实施例提供的一种显示装置，驱动器103控制支架102在平行于显示面板110的平面上绕轴1021转动，从而带动固定在支架102上的多个感应器在平行于显示面板110的平面上绕轴1021转动，当用户所需的感应 器转动至窗口时，使得支架102停止转动。这样一来，仅需在显示装置中设置一个窗口111，即可实现多个感应器依次通过窗口111暴露，从而正常工作，同时减小了窗口111的个数和大小，进而减小窗口在显示装置中所占的面积，尤其是对于全面屏的显示装置，可大大增加显示区域的面积，提高屏占比。平行于显示面板110的平面，指的是与显示面板110的显示区域所在的平面平行的平面。
本公开一些实施例中，如图2A和图2B所示，壳体101包括边框1011和后壳1012，显示面板110位于边框1011和后壳1012围成的空间内。此时，窗口111还可以位于边框1011上或后壳1012上。
本公开一些实施例中，窗口111可以设置在后壳1012上，此时多个感应器设置在支架102靠近后壳1012的表面，支架102转动使得多个感应器依次通过窗口111暴露出来。
本公开一些实施例中，显示面板110包括显示区域和位于显示区域至少一侧的非显示区域，窗口111可以设置在显示面板110的显示区域，也可以设置在显示面板110的非显示区域，窗口111的深度方向与显示面板110的厚度方向相同。
对于包含两个显示面板的双面显示面板，显示面板110包括第一显示面板和第二显示面板，例如第一显示面板为彩色显示面板、第二显示面板为电子纸显示面板。此时，可以省略后壳1012的使用，而是将第二显示面板作为后壳1012，支架102设置在第一显示面板和第二显示面板之间。并且，在此情况下，窗口111也可以位于第二显示面板中。第一显示面板的显示侧为第一显示面板背离第二显示面板的一侧，且第二显示面板的显示侧为第二显示面板背离第一显示面板的一侧。
本公开一些实施例中，如图3和图4所示，支架102为圆形，多个感应器在支架102上呈圆形分布。多个感应器固定在支架102靠近显示面板110的表面，支架102转动使得多个感应器中的一个通过窗口111暴露出来。在本公开一些实施例中，窗口111更大一些，支架102转动使得多个感应器中的两个或更多个通过窗口111暴露出来。作为示例，图3和图4仅示出了摄像头120、指纹传感器130和光学体征识别传感器140。需要说明的是，在一些实施例中，支架102可以为圆形的一部分，例如扇形；在此情况下，多个感应器在支架102上可以呈扇形分布。例如，在图3中，支架102为圆形，但是为了使得支架102在较小的转动角度下就能够依次暴露出其上所有的感应器，因此将支架102上的感应器设置得较为紧密，从而使得多个感应器在 圆形支架上呈扇形排布。在一些实施例中，多个感应器排布成的扇形所对应的角度小于180°，例如，150°、120°、90°、60°、30°、15°等。
本公开一些实施例中，如图3所示，驱动器103包括调节杆1030，调节杆1030的一端与支架102连接，另一端可被用户触摸到。框架1011包括开口1013，调节杆1030从开口1013伸出，从而可被用户触摸到。用户可以手动拨动调节杆1030使得支架102绕轴1021转动。本公开一些实施例中，调节杆1030的一端可以与支架102铰接，在无需使得支架102转动时，用户可以转动调节杆1030使其朝向显示装置100收回，避免影响显示装置的外观。例如，调节杆1030可以由图3所示的前后方向(即，垂直于纸面的方向)转动至图3所示的左右方向，从而朝向显示装置100收回。
但需要注意到，当用户手动拨动调节杆1030使支架102转动时，由于用户可能并非专业人士，因此可能不知道将调节杆1030拨动到哪个位置时所选择的感应器是满足需求的，从而增大了使用所述显示装置的复杂程度。
本公开一些实施例中，提供了一种使支架102自动转动的驱动器103，从而使所述显示装置的操作使用更为简易。驱动器103包括直流电机1031和传动转子1032，如图5A所示，直流电机1031的输出轴10310与支架102的轴1021垂直，传动转子1032与支架102配合将直流电机1031输出的旋转运动传递至支架102。在一些实施例中，传动转子1032与支架102上均设置有齿，并使传动转子1031和支架102形成锥齿轮，传动转子1032与支架102互相啮合。直流电机1031接收到用户指令，控制传动转子1032在垂直于显示面板的平面上转动，如沿图5A所示的第一方向转动(垂直于纸面向外)，从而带动支架102在平行于显示面板的平面上转动，如沿图5A所示的第二方向转动(在纸面内逆时针转动)。
如图5B所示，在本公开一些实施例中，当显示装置为一种手机时，直流电机1031可以为手机中产生震动功能的偏振电机，此时直流电机的输出轴10310上还设置有偏振转子1036。这样当直流电机1031转动从而使支架102转动时，同时还会使手机产生震动，从而提示用户正在进行感应器的切换。但如果用户不希望在切换感应器时使手机产生震动，则可以使直流电机1031反向旋转，从而使得直流电机1031的输出轴仅带动传送转子1032转动、而不带动偏振转子1036转动。
本公开一些实施例中，如图6A和图6B所示，直流电机1031的输出轴10310与支架102的轴1021平行，传动转子1032与支架102配合将直流电机1031输出的旋转运动传递至支架102。在一些实施例中，传动转子1032与支 架102上均设置有齿，并使传动转子1031和支架102形成圆柱齿轮，传动转子1032与支架102互相啮合。直流电机1031接收到用户指令，控制传动转子1032在平行于显示面板的平面上转动，从而带动支架在平行于显示面板的平面上转动，例如，支架沿如图6B所示的第二方向转动(逆时针转动)，传动转子1032沿如图6B所示的第三方向转动(顺时针转动)，但两者均在平行于显示面板的平面内转动。
当显示装置较厚时，显示面板与壳体之间的空间充足，可以采用直流电机1031的输出轴10310与支架102的轴1021平行的设置方式；当显示装置较薄时，采用直流电机1031的输出轴10310与支架102的轴1021垂直的设置方式，以节省显示面板与壳体之间的空间，如图5A中显示装置的厚度通常会小于如图6A中显示装置的厚度。
本公开一些实施例中，为了防止直流电机输出的转速较快，传动转子1032与支架102直接啮合使得支架的转速较快，不便于多个感应器之间的切换，如图7A和图7B所示，驱动器103还包括传动轴1035，传动轴1035上的第一传动轮10351与传动转子1032啮合，传动轴1035上的第二传动轮10352与支架102啮合，直流电机1031接收到用户指令，控制传动转子1032转动，传动转子1032带动传动轴1035转动，从而使得支架102转动。第一传动轮10351和第二传动轮10352可以用来改变驱动器103中的传动比。
如图9所示，当用户需要使用多个感应器中的任意一个感应器时，用户可以触发显示面板110上的选择感应器的按键，例如用户点击显示面板110上的“选择感应器”。显示装置100检测到用户的操作，显示面板110显示选择界面，该选择界面包括与多个感应器对应的选项，例如图9所示的选项包括指纹传感器、光学体征识别传感器和距离传感器；用户选择与所需的感应器对应的选项后，直流电机1031接收到用户指令，控制传动转子1032转动，从而带动支架102在平行于显示面板的平面上绕轴1021转动。例如，显示装置100检测到用户点击“指纹传感器”的操作，则控制驱动器103驱动支架102转动，使得指纹传感器130转动至窗口111的位置。若显示装置100检测到用户点击“光学体征识别传感器”的操作，则控制驱动器103驱动支架102转动，使得光学体征识别传感器140转动至窗口111的位置。若显示装置100检测到用户点击“距离传感器”的操作，则控制驱动器103驱动支架102转动，使得距离传感器150转动至窗口111的位置。
或者，在一些实施例中，如图10所示，显示装置100检测到用户点击显示面板110上的“选择感应器”操作，显示面板110上显示提示信息“当前 传感器为指纹传感器，是否切换传感器”，若显示装置检测到用户点击“是”的操作，显示面板110显示选择界面，该选择界面包括与多个感应器对应的选项，用户选择某一选项，则切换感应器；若显示装置检测到用户点击“否”的操作，则不切换感应器。
为了便于感应器的维修和更换，支架102需能够从显示装置中拆卸出来，如果支架102与传动转子1032一直处于啮合状态，则增大了将支架102从显示装置中拆卸出来的难度，因此支架102与传动转子1032需能够从啮合状态变为分离状态。为此如图8A所示，驱动器103还包括电磁开关1033和电磁铁1034。电磁铁1034设置在直流电机1031靠近传动转子1032的一侧。电磁开关1033接收到第一用户指令，控制电磁铁1034所在回路中的电流方向，使得电磁铁1034与传动转子1032之间产生吸引力，进而控制传动转子1032沿直流电机1031的输出轴10310向远离支架102的方向移动，例如在图8A中向右移动，使得传动转子1032与支架102脱离啮合，从而便于支架102的拆卸和维修。当需要传动转子1032与支架102啮合时，电磁开关1033响应于接收到的第二用户指令，改变电磁铁1034所在回路中的电流方向，使得电磁铁1034与传动转子1032之间产生排斥力，进而控制传动转子1032沿直流电机1031的输出轴10310向靠近支架102的方向移动，例如在图8A中向左移动，使得传动转子1032与支架102啮合，传动转子1032跟随直流电机1031的输出轴10310转动并带动支架102转动。
如图8B所示，为了使传动转子1032既能够跟随直流电机1031的输出轴10310转动、又能够相对于直流电机1031的输出轴10310移动，可以在传动转子1032的内侧壁上设置凹槽10321(或凸起)，并在直流电机1031的输出轴10310的外侧壁上设置凸起10311(或凹槽)，从而在凹槽10321和凸起10311配合后，使传动转子1032和直流电机1031的输出轴10310能够实现前面所描述的运动。
传动转子1032可以由永磁体制作而成，传动转子1032靠近电磁铁1034的一端为N极，传动转子1032远离电磁铁1034的一端为S极。或者反过来，传动转子1032靠近电磁铁1034的一端为S极，传动转子1032远离电磁铁1034的一端为N极。当电磁开关1033接通时，电磁铁1034通过电磁感应产生磁性，吸引传动转子1032向靠近电磁铁1034的方向移动，或者排斥传动转子1032向远离电磁铁1034的方向移动，这和电磁铁1034产生的电磁场以及传动转子1032靠近电磁铁1034的一端是N极还是S极有关。可以改变电磁铁1034所在回路中电流的流向，从而改变电磁铁1034对传动转子1032施加的 力，例如将吸引力改变为排斥力，或将排斥力改变为吸引力。
若在直流电机1031接收到用户指令之前，与窗口111正对设置的感应器，即为与用户指令对应的感应器，则直流电机1031接收到用户指令后，无需控制支架102转动。
本公开一些实施例中，如图3和4所示，显示装置还包括限位结构104，该限位结构104设置在支架102和壳体101的后壳1012之间，并被配置为当多个感应器中的一个感应器转动至窗口111的位置时，使支架102停止转动。限位结构104包括至少一个凸起，该凸起的一端固定在后壳1012靠近显示面板110的表面，另一端与支架102抵靠。通过凸起对支架102的摩擦力，使得用户所需的感应器转动至窗口111的位置时，支架102停止转动。其中，不对限位结构104的形状进行限定，只要其能够使支架102停止转动即可。例如，在图3和图4中，限位结构104靠近支架102的顶端在平行于纸面的平面内的形状为三角形，但并不局限于此，也可以为矩形、梯形等形状。
本公开一些实施例中，如图11所示，支架102包括至少一个限位槽1021，该至少一个限位槽1021位于支架102远离显示面板110的表面上，该至少一个限位槽1021与限位结构104配合，使得支架102停止转动。图11为图3和图4所示的支架102展开成位于一条直线上的等效示意图。在本公开一些实施例中，如图11所示，限位结构104抵靠支架102的一端能够嵌于限位槽1021中，以使得支架102停止转动。如图12所示，以支架102逆时针(在图12中即为向垂直于纸面内)转动和停止为例，在图12中将支架展开成位于一条直线上后等效为支架向右移动和停止，显示装置100控制驱动器103对支架102施加水平向右的力F，则支架102对限位结构104施加同样的水平向右的力F。在限位结构104的受力面上，将力F沿着互相垂直的两个方向分解为力F1和力F2。力F1与限位结构104的受力面垂直，不能使支架102从限位结构104中脱出；而力F2与限位结构104的受力面平行，能够使得支架102从限位结构104中脱出向右运动。当所需的感应器转动至窗口111的位置时，驱动器103撤去对支架102的作用力，限位结构104与相应的限位槽1021配合，从而在没有力F的作用下使得支架102停止运动。
在本公开一些实施例中，限位槽1021与限位结构104之间具有磁性吸引力，可将限位结构104靠近支架102的顶端吸附于限位槽1021中，以使得支架102停止转动。本公开一些实施例中，限位结构104的受力面具有一定的粗糙度，从而施加给限位槽1021的表面摩擦力足以使得转 动中的支架102停止转动。
在本公开一些实施例中，如图11所示，支架102远离显示面板110的表面还包括至少一个缓冲槽1022。该至少一个缓冲槽1022被配置为与限位结构104相互作用，对支架102的转动起到缓冲作用，避免当需要支架102停止时，因支架102转动过快，而无法仅利用限位槽1021将支架固定住。缓冲槽1022的深度小于限位槽1021的深度；或者，限位槽1021和缓冲槽1022与限位结构104之间均具有磁性吸引力，且限位槽1021正对限位结构104的吸引力大于缓冲槽1022正对限位结构104的吸引力；或者，限位槽1021的表面摩擦力大于缓冲槽1022的表面摩擦力；从而使得缓冲槽1022对支架102的限位作用小于限位槽1021对支架102的限位作用。
为此目的，在本公开一些实施例中，可以使得缓冲槽1022的深度小于限位槽1021的深度，并且限位槽1021正对限位结构104的吸引力大于缓冲槽1022正对限位结构104的吸引力；或者，缓冲槽1022的深度小于限位槽1021的深度，并且限位槽1021的表面摩擦力大于缓冲槽1022的表面摩擦力；或者，缓冲槽1022的深度小于限位槽1021的深度，并且限位槽1021正对限位结构104的吸引力大于缓冲槽1022正对限位结构104的吸引力，限位槽1021的表面摩擦力大于缓冲槽1022的表面摩擦力。
本公开一些实施例中，沿限位槽1021的深度方向(即，图11所示的上下方向)，限位结构104的高度可调；若限位结构104用于使支架102停止转动，则沿限位槽1021的深度方向，限位结构104伸长，直至伸入到限位槽1021中，以固定支架102。否则限位结构104靠近支架102的表面收缩至与限位槽1021的顶面平齐(即，图11所示支架102的下表面)，避免支架102转动过程中，限位结构104影响支架102的转动。例如，如图13所示，图13显示的是支架102展开成位于一条直线上的等效示意图，限位结构可以包括设置在后壳1012上的固定部1041和套设在固定部1041中并可在固定部内滑动的伸缩部1042，第一电磁开关1031接受到用户指令后闭合，控制支架102转动，伸缩部1042在支架102所施加的力的作用下向靠近固定部1041的方向转动并产生形变，从而收缩至与限位槽1021的顶面平齐；当所需的感应器转动至窗口位置时，限位结构104正好与相应的限位槽位置对应，此时支架102施加给限位结构104的作用力消失，伸缩部1042恢复形变并伸入到限位槽1021中，与限位槽配合使得支架102停止。
本公开一些实施例中，如图14所示，图14显示的是支架102展开成位于一条直线上的等效示意图，显示装置还包括支撑结构105，支撑结构105用 于支撑显示面板110与壳体101，例如支撑结构105支撑在显示面板110与后壳1012之间，以预留放置限位结构104和感应器的空间。当显示面板110包括第一显示面板和第二显示面板，并且第二显示面板代替壳体101中的后壳1012时，支撑结构105支撑在第一显示面板与第二显示面板之间。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
