在现有技术的显示装置中，当屏下摄像头对应地设置于所述显示装置所具有的背光模组的开孔下方时，所述开孔将仅仅作为所述屏下摄像头用以接收环境光的收发通道。由于所述开孔的内侧并未设置有任何光源提供亮度，使得所述显示装置在使用时，所述背光模组于所述开孔的区域将处于闲置状态而无法提供任何显示效果。本申请基于上述技术问题提出了一种显示装置。

在本实施例中，所述显示装置300还可以包括位于所述背光模组100一侧且远离所述显示面板200的摄像模组400，所述摄像模组400与所述背光孔120对应。所述摄像模组400在所述背光单元110上的正投影位于所述背光孔120内。
在本实施例中，所述显示装置300是否设置有所述摄像模组400，本申请不作具体限制。
本申请提出了一种显示装置300，包括显示面板200、背光模组100及摄像模组400。所述背光模组100包括背光单元110，开设有背光孔120，所述摄像模组400与所述背光孔120对应；导光环130，设于所述背光孔120内侧，所述导光环130包括入光面131和出光面132，所述导光环130用于将进入所述导光环130中的光束导向所述背光孔120对应的显示面板区域210；光源部件140，用于为所述导光环130提供光源。本申请通过在摄像模组400对应的区域设置一背光孔120及在所述背光孔120内设置一导光环130，使得光源部件140提供的光源能通过导光环130导向所述背光孔120对应的显示面板区域210。使得当所述摄像模组400中摄像头启动时，所述光源142关闭，当所述摄像模组400中的摄像头不启动时，所述光源142开启或关闭，故能够使所述显示面板200上的通孔或盲孔重新具有显示能力，且依旧维持摄像模组400的影像质量。
下面结合具体实施例对本申请的技术方案进行说明。
实施例一
请参阅图1~3，所述出光面132所在平面与所述入光面131所在平面呈锐角。
请参阅图1，所述出光面132与所述入光面131的夹角为锐角。在实际应用中，所述出光面132与所述入光面131之间的夹角可以为10度、20度、30度、45度、50度、60度、70度、80度等，用来保障从所述入光面131进入的光束。
在从所述出光面132射出时，向所述背光孔120对应的所述显示面板区域210投射，以补偿所述摄像模组400对应的所述显示面板区域210额外光源，使得显示面板200的这部分区域能够正常显示，且不影响所述摄像模组400的正常工作。
在本实施例中，所述背光模组100还包括一光线阻隔膜150。所述光线阻隔膜150设于所述导光环130和所述背光单元110之间。所述光线阻隔膜150用于阻隔背光模组100的光线，以及防止在摄像模组400进行摄像时受到所述背光模组100的光源142所发出的光的影响。
在图1的基础上，所述显示装置300所具有的所述导光环130更进一步依据不同的背光单元110的设计，相应的变化为如图2或图3所示例的剖面结构，以同样可透过所述导光环130的所述出光面132的设置，引导所述光源部件140所发射的光束朝对应于所述背光孔120处的所述显示面板区域210发射，藉此为对应于所述背光孔120处的所述显示面板区域210提供适当的亮度。
在本实施例中，当所述导光环130设置为图3或图4所具有的剖面结构时，所述导光环130与所述背光单元110的交界处所设置的所述光线阻隔膜150亦将相应地变更其形状，以有效阻隔所述背光单元110内部的光线漏出至所述背光孔120的中心区域，从而避免影响到所述摄像模组400的摄像质量。
在本实施例中，所述光源142可以包括LED光源或mini LED光源中的一种。下述实施例中的光源部件140可以与本实施例相同。
在本实施例中，所述导光环130可以为透明材质或雾面材质制备。透明的导光环130可以有效地引导光源部件140所射出的光束通过所述出光面132朝向对应于所述背光孔120处的所述显示面板区域210发射，降低光源部件140的光损现象。下述实施例中的导光环130材料可以与本实施例相同。
请参阅图1，所述显示装置300还包括控制部件160。
所述控制部件160分别与所述摄像模组400和所述光源部件140电连接。所述控制部件160用于当所述摄像模组400启动时，使所述光源部件140关闭，使所述摄像模组400可不受干扰地获取外界影像数据。当所述摄像模组400关闭时，则可依据显示面板200的实际显示情况控制所述光源部件140开启或关闭。
在本实施例中，当所述摄像模组400启动时，所述光源部件140将关闭，以使得所述摄像模组400可不受影响地接收来来自外界的环境光源进行感光。当所述摄像模组400不启动时，所述光源部件140则能够依据显示面板200的实际显示情况，使其处于开启状态并朝所述显示面板200的显示面板区域210发射光束以提供亮度。
或者，所述摄像模组400能够在不显示时使所述光源部件140处于关闭状态而不朝向所述显示面板200的所述显示面板区域210发射光束，使对应于所述背光孔120的所述显示面板区域210处于全黑状态，故能使现有技术中处于闲置状态而无法提供任何显示效果的显示面板200得以重新具有显示能力，且依旧维持所述屏下摄像头所能获取的影像质量，提升终端产品（即：采用全面屏技术的显示面板200）的应用场景和使用体验，从而具有竞争力。
本实施例通过在摄像模组400对应的区域设置一背光孔120及在所述背光孔120内设置一导光环130，使得光源部件140提供的光源能通过导光环130导向所述背光孔120对应的显示面板区域210。使得当所述摄像模组400中摄像头启动时，所述光源142关闭，当所述摄像模组400中的摄像头不启动时，所述光源142开启或关闭，故能够使所述显示面板200上的通孔或盲孔重新具有显示能力，且依旧维持摄像模组400的影像质量。
实施例二
本实施例与实施例一相同或相似，不同之处在于：
在图1~3的基础上，所述出光面132的表面可进一步具有微结构，使自所述出光面132射出的光线可因微结构的设置而尽量均匀的分布在所述背光孔120内侧，从而使对应于所述背光孔120处的所述显示面板区域210具有均匀的亮度。
请参阅图4~6，所述出光面132所在平面与所述入光面131所在平面垂直或呈一锐角。
在本实施例中，当所述出光面132所在的平面与所述入光面131所在的平面呈一锐角时，便于光线从所述出光面132折射进入所述背光孔120内时朝向上方，即背光孔120的孔口方向传播。
在本实施例中，所述背光孔120用于容置摄像模组400、或者所述背光孔120与摄像模组400的镜头位置对应设置。
在本实施例中，所述显示装置300同样包括与实施例一相同的控制部件（未画出）。所述控制部件可以根据实际情况控制所述光源部件140以及所述摄像模组400。
当所述摄像模组400中摄像头开启时，所述光源部件140处于非工作状态，所述背光孔120作为所述摄像模组400接收环境光的通道。当所述摄像模组400中摄像头关闭时，所述光源部件140处于工作状态，所述光源部件140中的光源142发出的光线穿过所述导光环130为所述背光孔120提供光。
在本实施例中，所述导光环130具有对光线全反射和折射的作用，便于光线尽可能地向所述背光孔120的区域传播。本实施例通过在所述背光孔120内侧设置导光环130以及光源部件140，从而在所述背光孔120内侧提供了光源，解决了在摄像头关闭时在所述背光孔120对应位置的颜色较暗的问题。
本实施例中，所述背光模组100还包括一光线阻隔膜150，所述光线阻隔膜150设于所述导光环130和所述背光单元110之间。设置所述光线阻隔膜150的目的是为了阻隔背光模组100的光线，防止在摄像头进行摄像时受到所述背光模组100的光源部件140所发出的光的影响。
请参阅图5~6，在所述导光环130靠近所述光线阻隔膜150一侧还包括一反光面133。所述反光面133所在的平面与所述入光面131所在的平面一垂直或呈一锐角。
在本实施例中，所述光源142的光线（图5、图6中箭头表示光线传播方向）从所述入光面131进入所述导光环130内，经所述反光面133反射使得光线从所述出光面132射出进入所述背光孔120内，从而给所述背光孔120提供光。所述反光面133所在平面与所述入光面131所在平面呈一锐角，更便于所述光源142的光线从所述入光面131进入所述导光环130内后经反射进入所述背光孔120。
请参阅图4，所述导光环130包括所述入光面131及所述出光面132而不包括所述反光面133，所述出光面132所在平面与所述入光面131所在平面呈一锐角。
请参阅图5，所述出光面132所在平面与所述入光面131所在平面垂直，所述反光面133所在平面与所述入光面131所在平面呈一锐角。
请参阅图6，所述出光面132所在平面与所述入光面131所在平面呈一锐角，且所述反光面133所在平面与所述入光面131所在平面也呈一锐角。
本申请的具体实施例不限于上述几种导光环130结构，只要满足所述光源142发射的光线经所述导光环130传播进入所述背光孔120内，其均属于本发明保护范围。
在本实施例中，所述导光环130的材质可以是塑料，也可以是光学级的玻璃，其材质优选具有一定折射率，使光线尽可能地向所述背光孔120区域传播。
请参阅图7，所述入光面131可以由处于同一平面若干菲涅尔透镜160一体形成。即多个所述菲涅尔透镜160呈环形分布于所述入光面131。
在本实施例中，所述光源142与所述菲涅尔透镜160一一对应设置。所述光源142与所述菲涅尔透镜160的数量相等。
在本实施例中，所述光源142位于所述菲涅尔透镜160的焦点位置。任一所述光源142发出的光均可经过与之对应的菲涅尔透镜160后形成平行光，具体请参阅图5~6。
请参阅图7，所述菲涅尔透镜160具有若干个同心布置的环形齿状结构161，以及被所述环形齿状结构161环绕的凸透镜结构。所述菲涅尔透镜160又名螺纹透镜，由聚烯烃材料注压而成的薄片或由玻璃制作。所述菲涅尔透镜160的一面为平面，另一面刻录了由小到大的同心圆，并尽可能多的去掉光学材料以减薄厚度，而保留表面的弯曲度，即形成所述同心布置的环形齿状结构161。
请参阅图5~6，所述光源142位于所述菲涅尔透镜160焦点位置发出光线，从所述环形齿状结构161一侧入射，经过所述菲涅尔透镜160后以平行光方式射出，因此本实施例的所述菲涅尔透镜160等效于普通菲涅尔透镜160减薄后的效果。
在本实施例中，所述驱动电路板141的形状及尺寸与所述导光环130的形状及尺寸相适配，即呈环形设置。
在本实施例中，所述光源142可以呈阵列式分布于所述驱动电路板141上。
由于所述光源142的光型较发散，为了能更好地实现导光功能以及尽可能利用光效，所述导光环130的入光面131可以包括多个所述菲涅尔透镜160。所述光源142可以位于所述菲涅尔透镜160的焦点位置，以实现所述光源大角度的光线准直作用，避免了发散光造成所述背光模组100的漏光问题。
请参阅图4，所述导光环130的所述入光面131卡设于所述背板111上，所述光源142与所述背板111的上表面处于同一平面内。这样更利于所述导光环130固定在所述背光孔120内侧。当然，在其他实施例中，所述光源142和所述入光面131也可设置在所述导光环130的其他位置，其变形均属于本发明保护范围。
本实施例提供的所述显示装置300通过在所述背光孔120内侧设置所述导光环130以及所述光源部件140，解决了所述背光孔120内侧无光源提供亮度的问题，以及解决了所述显示装置300在摄像头关闭进入显示状态时在所述背光孔120对应位置的颜色较暗的技术问题。
实施例三
本实施例与实施例二相同或相似，不同之处在于：
请参阅图8~12，所述出光面132由处于同一平面的若干微透镜薄膜170一体形成。
在本实施例中，所述微透镜薄膜170呈环形分布于所述出光面132。所述入光面131所在的平面与所述微透镜薄膜170的焦点O所在平面重合。所述入光面131设有多个透光孔171，每一透光孔171与每一微透镜薄膜170相对应设置，这样便于所述光源142发射出的光线经所述入光面131进入并从所述出光面132的所述微透镜薄膜170进行折射射出，从而能够得到最终射出的平行光束。
在本实施例中，所述光源部件140的设置可以与实施例二相同。所述驱动电路板141可以为柔性电路板，其是以聚酰亚胺或聚酯薄膜为基材制成，具有配线密度高、重量轻、厚度薄的特点。
在本实施例中，所述透光孔171可以位于所述微透镜薄膜170的焦点O所在的平面。即所述透光孔171处于所述微透镜薄膜170的焦平面，大部分光线经微透镜薄膜170后主光线方向变得有指向性，该方向与所述透光孔171和所述微透镜薄膜170的焦点O的位置有关。
在本实施例中，当所述透光孔171与所述微透镜薄膜170的焦点O重合时，则所述光源142发射出的光线（图8、图9中用箭头表示）经所述微透镜薄膜170折射形成垂直于所述入光面131的平行光束。当所述透光孔171偏离焦点O且处于所述微透镜薄膜170的焦平面时，所述光源142发出的光线经所述微透镜薄膜170折射形成与入射面成一定角度的平行光束。
因此，本实施例可以通过调整所述透光孔171相对于所述微透镜薄膜170的焦点O的位置，以控制入射光的出光方向，实现了将所述光源142发出的光导向某一方向。
请参阅图8，所述背光模组100还包括一金属层反射层172。所述金属层反射层172设于所述导光环130的入光面131朝向所述光源142的一侧。所述金属层反射层172上阵列排布有多个透光孔171。
在本实施例中，所述入光面131所在的平面与所述微透镜薄膜170的焦点O所在平面重合，从而使所述金属层反射层172所在的平面与所述微透镜薄膜170的焦点O所在的平面重合，即所述透光孔171位于所述微透镜薄膜170的焦点O所在平面内。
在本实施例中，设置所述透光孔171使得其透过所述光源142发射出的光线可近似当作点光源。
请参阅图8，所述光源部件140还包括一漫反射层143。所述漫反射层143设于所述驱动电路板141上，所述光源142暴露在所述漫反射层143上。
在本实施例中，所述漫反射层143用于反射未通过所述透光孔171的光线，同时所述漫反射层143与所述金属层反射层172相平行设置。未通过所述透光孔171的光线经所述金属层反射层172反射再经所述漫反射层143漫反射，这样在所述金属层反射层172和所述漫反射层143之间充满了方向随机的光线，从而达到多次利用所述光源142发射的光线。本发明重复利用多次反射的光线，减小了光效损失，达到了节能效果。
在本实施例中，所述漫反射层143的材质可以包括白色油墨，其反光效果良好且不易吸收光线。
在本实施例中，每一透光孔171均位于与其对应的每一微透镜薄膜170的焦点O远离所述导光环130中心的一侧。相邻两个所述透光孔171的中心与相邻两个所述微透镜薄膜170的焦点O的间距相等。这样所述透光孔171均偏离所述微透镜薄膜170的焦点O，则所述光源142发射出的光线经所述微透镜薄膜170折射形成与入射面成一定角度的平行光束，且该平行光束均被导向所述导光环130中心的一侧。
请参阅图10~11，所述光源142呈阵列式排布于所述驱动电路板141上。所述光源142的一侧为发光侧。所述光源142呈阵列式排布的方式有多种形式。
请参阅图10，所述光源142的排布方向一致。
请参阅图图11，所述光源142的排布方向的交点为所述驱动电路板141的中心点。
在本实施例中，所述透光孔171位于所述微透镜薄膜170的焦点O所在平面内，透光孔171并未与焦点O重合且远离所述背光孔120的一侧。这样所述光源142发射出的光线经所述透光孔171进入所述微透镜薄膜170内进行折射射出，从而能够形成朝向所述背光孔120的平行光束。
本实施例中，所述背光模组100的形状及尺寸与所述背光孔120的形状及尺寸相适配。所述背光孔120优选为圆形孔。
本实施例中，所述导光环130、所述光源142均呈环形，优选为圆环形，即与所述背光孔120优选为圆形孔时相适配。
请参阅图12所示，所述背光模组100还包括一光线阻隔膜150，所述光线阻隔膜150设于所述背光模组100和所述背光单元110之间。设置所述光线阻隔膜150的目的是为了阻隔所述背光模组100的光线，防止在摄像头进行摄像时受到所述背光模组100的光源142的影响。
本实施例提供的所述显示装置300通过在所述背光孔120内侧设置所述导光环130以及所述光源142，解决了所述背光孔120内侧无光源提供亮度的问题，以及解决了所述显示装置300在摄像头关闭进行显示状态时在所述背光孔120对应位置的亮度偏暗的技术问题。
在上述实施例中，所述显示装置300还可以包括位于所述背光模组100与所述显示面板200之间的遮光胶180。
本申请以实施例二为例进行说明，请参阅图13。
所述遮光胶180的下表面部分贴附于所述导光环130的上表面，另一部分贴附于所述上增光片116的上表面（即所述背光模组100的上表面）。
所述遮光胶180的上表面则贴附于所述显示面板200的下表面，从而所述遮光胶180将所述背光模组100和所述显示面板200粘附结合在一起。所述遮光胶180起到连接所述背光模组100和所述显示面板200的作用，并且可以防止从所述背光孔120位置漏光，因此所述遮光胶180的形状及尺寸与所述背光孔120的形状及尺寸相适配，即所述遮光胶180呈环形环绕所述背光孔120，也就是说在对应所述背光孔120的位置不设置所述遮光胶180。
在上述实施例中，所述背光单元110可以包括从下至上依次层叠设置的反射片112、导光板113、扩散片114、下增光片115和上增光片116。
所述反射片112设于所述背板111上；所述导光板113设于所述反射片112上；所述扩散片114设于所述导光板113上；所述下增光片115设于所述扩散片114上；所述上增光片116设于所述下增光片115上。
所述背光孔120从下至上依次贯穿所述背板111、所述反射片112、所述导光板113、所述扩散片114、所述下增光片115和所述上增光片116。
所述扩散片114对光线扩散以提供一个均匀的面光源。所述下增光片115和所述上增光片116可增强光源的亮度。所述背光单元110的发光效果将直接影响到所述背光模组100的视觉效果。
在上述实施例中，所述显示面板200包括下偏光片201、阵列基板202、彩膜基板203和上偏光片204，具体请参阅图13。
在本实施例中，所述下偏光片201，设于所述背光模组100上；所述阵列基板202设于所述下偏光片201上；所述彩膜基板203设于所述阵列基板202上；所述上偏光片204设于所述彩膜基板203上；其中所述下偏光片201和所述上偏光片204在对应所述背光孔120位置设有通孔，所述通孔能够提高所述显示面板200的透光率。所述遮光胶180的上表面贴附于所述下偏光片201的下表面将所述背光模组100和所述显示面板200粘附结合在一起。
所述显示装置300可装设于具有通孔（如：挖孔、水滴、凹口、及面外等）或具有盲孔的所述显示面板200，从而消弭当所述显示面板200具有通孔或盲孔时，所述通孔区域或所述盲孔区域无法用于显示的问题，且所述背光单元110可使用背板111或反射膜作为背面，以均匀或有效利用所述背光单元110所发射的光。
综上所述，藉由本揭示的所述导光环130与所述光源部件140的设置，使得所述显示装置300所具有的所述背光模组100可于所述背光孔120的区域提供光线与亮度控制，使现有技术中处于闲置状态而无法提供任何显示效果的显示面板200上的通孔或盲孔得以重新具有显示能力，且依旧维持所述摄像模组400所能获取的影像质量，进而提升终端产品的应用场景和使用体验，从而具有竞争力。
本实施例中的所述显示装置可以为手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
