Description

显示装置 技术领域
本申请涉及显示技术领域，尤其涉及一种显示装置。
 背景技术
随着显示技术的发展，终端设备具有高屏占比的显示屏已经成为主流趋势。由于终端设备配置有采光需求的功能器件如摄像头、光线传感器等，显示屏的屏占比难以实现最大化。
现有技术的显示装置为了使显示屏的屏占比最大化，将摄像头设置在显示屏的下方。如图1所示，显示装置包括显示面板Pa、背光模组BLU、摄像组件Ca、遮光胶3、金属框1和密封胶2。背光模组BLU具有开口，摄像组件Ca设置在开口内。在该显示装置中，与开口对应的显示面板Pa仅作为摄像组件Ca的采光窗口而不具有显示功能。此外，为防止背光模组BLU漏光而影响摄像组件Ca的拍摄，必须设置用遮光胶3、金属框1和密封胶2遮蔽背光模组BLU横向扩散至开口的光，由于引用遮光胶3、金属框1和密封胶2，使得与遮光胶3对应的显示面板Pa呈现黑边，从而无法实现全屏显示。若不设置遮光胶3、金属框1和密封胶2，则会导致背光模组BLU漏光。

下面通过具体实施例对本申请提供的显示装置进行详细的阐述。
请参考图2，图2为本申请实施例提供的显示装置的第一种结构示意图。本申请实施例提供一种显示装置，显示装置100包括第一背光模组10、显示面板20和感光组件30，显示面板20设置在第一背光模组10上。第一背光模组10具有开口Op，开口Op贯穿第一背光模组10。第一背光模组10包括基板101、多个发光单元103和至少一个阻光结构104，多个阻光结构104设置在基板101上，且围绕开口Op置。发光单元103设置在基板101上，且发光单元103设置在阻光结构104远离开口Op的一侧。感光组件30设置在第一背光模组10远离显示面板20的一侧，且感光组件30对应开口Op设置。在本申请实施例中，通过在发光单元103靠近开口Op的一侧设置阻光结构104，从而遮蔽从第一背光模组10横向漏出的光线，改善背光模组漏光的问题，并且，本申请实施例提供的显示装置100可以用于避免第一背光模组10漏光而影响感光组件30的拍摄效果的问题。
需要说明的是，本申请实施例中的感光组件30可以是摄像组件。
应该理解的是，在本申请实施例中，显示面板20包括第一区域和第二区域，第一区域围绕第二区域的至少一部分。其中，开口Op对应于第二区域设置，感光组件30对应于开口Op设置。
在本申请实施例中，第一背光模组10还包括基板101、驱动电路层102、封装胶层105、反射层106、光传导层107、扩散层108和增亮层109。
其中，基板101可以是金属板，基板101用于支撑位于其上方的膜层。
驱动电路层102设置在基板101远离基板101的一侧，多个发光单元103设置在驱动电路层102上。驱动电路层102包括用于驱动多个发光单元103发光的驱动电路。
在一些实施例中，发光单元103采用单色蓝光LED芯片或红绿蓝彩色LED芯片；当发光单元103采用蓝光LED芯片时，光传导层107中含有红绿量子点材料。
在一些实施例中，发光单元103包括至少一个第一发光单元1031和至少一个第二发光单元1032，至少一个第一发光单元1031设置在开口Op的周侧，至少一个第二发光单元1032设置在第一发光单元1031远离开口Op的一侧。第一发光单元1031和第二发光单元1032可以不同时发光。
具体的，当感光组件30开启时，第一发光单元1031不发光。也就是说，本申请实施例利用直下式背光模组，其可以实现Local Dimming(局部背光调节)功能。所谓Local Dimming，就是将屏后面的灯分成若干组，如32组、64组、128组，每组由若干灯珠组成串联方式，通常组数越多，分得越细，调光效果越好，每组灯的亮度由画面的亮度来决定，使得显示的效果更好，更节能省电。Local Dimming系统分为驱动装置和灯条，驱动装置由专用驱动IC接收T-CON板或主板提供的Local Dimming信号，并将Local Dimming信号解调后送到若干16通道的驱动器。本申请实施例通过局部背光调光，当感光组件30开启时，位于第一发光单元1031不发光，从而进一步提高了感光组件30的摄像效果。
在本申请实施例中，多个发光单元103可以包括多个第一发光单元1031，多个第一发光单元1031围绕阻光结构104设置。
应该理解的是，在本申请实施例中，第一发光单元1031和第二发光单元1032具有相同的结构，本申请为了方便描述而将发光单元103命名为第一发光单元1031和第二发光单元1032。
可以理解为，第一背光模组10具有第一子区A1和第二子区A2，第一发光单元1031位于第一子区A1，第二发光单元1032位于第二子区A2。
具体的，驱动电路包括Local Dimming背光驱动电路。该Local Dimming背光驱动电路包括L个LED驱动器、L*N个行驱动开关、L*(16-N)个列驱动开关，其中，发光单元103包括L*(16-N)组，每一组发光单元103的数量为N；每一LED驱动器的多个控制端与N个行驱动开关和(16-N)个列驱动开关的受控端一一对应连接；各N个行驱动开关的输入端用于接入直流电源，每一行驱动开关的输出端均与(16-N)组中的一发光单元103对应连接，(16-N)组发光单元103的阴极与(16-N)个列驱动开关的输入端一一对应连接，(16-N)个列驱动开关的输出端接地；其中，L个LED驱动器，用于输出时序控制信号，以控制L*N个行驱动开关20逐行导通，以及输出列驱动控制信号，以控制L*(16-N)个列驱动开关闭合/关断。L大于或等于1，N大于或等于2。
在一些实施例中，阻光结构104的高度H2大于发光单元103的高度H1。该方式可以阻挡发光单元103发出的光，避免发光单元103发出的光扩散至开口Op内，从而影响感光组件30的摄像效果。
在一些实施例中，阻光结构104的高度H1和宽度的比值的取值范围为1:2至1:2.5。阻光结构104可以通过喷涂工艺形成在基板101上。
在一些实施例中，阻光结构104靠近发光单元103的一侧面为弧形面，弧形面的曲率中心位于弧形面朝向开口Op的一侧。由于阻光结构104靠近发光单元103的一侧为弧形面，且弧形面的曲率中心位于弧形面朝向开口Op的一侧，当发光单元103发出的光反射至弧形面时，光线经过弧形面反射至显示面板20上，补偿边界黑边，从而提高屏占比。
在一些实施例中，阻光结构104在显示面板20的厚度方向上的截面形状可以是圆形或椭圆形。
在一些实施例中，阻光结构104的材料包括白色油墨。白色油墨具有较高的反射率，从而可以有效的反射光线至显示面板20，补偿边界黑边，从而提高屏占比。
其中，阻光结构104的反射率大于或等于85%。
应该理解的是，在本申请实施例中，阻光结构104围绕开口Op设置成一圈或多圈。多个围绕开口Op设置的阻光结构104形成圆形或方形。
封装胶层105设置在驱动电路层102上，且覆盖多个发光单元103和阻光结构104。
在一些实施例中，封装胶层105的厚度大于或等于阻光结构104的高度。该方式可以进一步阻挡发光单元103发出的光，避免发光单元103发出的光扩散至开口Op内，从而影响感光组件30的摄像效果。
反射层106、光传导层107、扩散层108和增亮层109依次层叠设置在封装胶层105上。反射层106用于发射发光单元103发出的光。光传导层107为有机塑料膜材质，通常可以为亚克力(PMMA)、聚对苯二甲酸乙二醇酯(PET)或者聚碳酸酯(PC)，光传导层107的透过率至少为85％。增亮层109用于提高背光的亮度。扩散层108一般采用PET(聚对苯二甲酸乙醇酯)或PC(聚碳酸酯)基材，正面光滑，反面粗糙。由于扩散层108中有扩散粒子，扩散粒子可以使光在膜片中均匀传导，达到混光均匀的目的，发光单元103发出的光线进入扩散层108中，进行多次折射、反射和散射，光线在扩散层108中横向传导，使得背光更加均匀。
显示装置100还包括第二背光模组40和粘胶50，第二背光模组40的出光面对应开口Op设置，且第二背光模组40设置在感光组件30靠近开口Op的一侧。
在一些实施例中，第二背光模组40的宽度大于或等于开口Op的宽度。粘胶50设置在第一背光模组10远离显示面板20的一侧，第二背光模组40贴附在粘胶50上。
在本申请中，当显示装置100显示画面且感光组件30未启动时，第一背光模组10的第一发光单元1031和第二发光单元以及第二背光模组40的发光单元启动，此时，显示面板20接收到来自对应的背光模组的光线，因此显示面板20实现全面屏的显示。
当显示装置100显示画面且感光组件30启动时，位于第二子区A2的第二发光单元1032发光，位于第一子区A1的第一发光单元1031不发光，第二背光模组40的发光单元关闭。外部光线传递至感光组件30，进而使得感光组件30获取外部光线以拍摄图像。当感光组件30启动时，阻光结构104可遮蔽从第一背光模组10横向漏出的光线，并且，第二背光模组40的光源关闭，确保了不会有来自于第二背光模组40的光线进入感光组件30的采光路径。并且，由于第一子区A1的第一发光单元1031不发光，增加第一背光模组10的漏光处到感光组件30的采光通道的横向距离，并且搭配阻光结构104的设置可以大幅度地减小因漏光而降低拍摄品质的风险。
显示面板20包括依次层叠设置在第一背光模组10上的第一基板201、液晶层202和第二基板203。在一些实施例中，第一基板201可以是阵列基板，第二基板203可以是彩膜基板。
请参考图3，图3为本申请实施例提供的显示装置100的第二种结构示意图。本申请实施例提供的显示装置100和图2提供的显示装置100的区别在于，显示装置100还包括遮光结构110，遮光结构110设置在光传导层107、扩散层108和增亮层109靠近开口Op的侧面。
本申请实施例将遮光结构110设置在光传导层107、扩散层108和增亮层109靠近开口Op的侧面上，从而可遮蔽从第一背光模组10横向漏出的光线。进一步减小因漏光而降低拍摄品质的风险。
另外，由于本申请实施例中的遮光结构110设置在光传导层107、扩散层108和增亮层109靠近开口Op的侧面上，无需在第一背光模组10上设置遮光胶以及封装胶，减小了显示装置100的黑边。
在一些实施例中，遮光结构110的宽度D1小于等于300微米。例如，遮光结构110的宽度可以是300微米、250微米、200微米、180微米、150微米、100微米、或50微米中的任意一者。本申请实施例将遮光结构110的宽度设置为小于等于300微米的宽度，一方面，保证了遮光结构110具备反射的性能，另一方面，相对于现有技术利用遮光胶进行遮光的方案而言，大大减小了显示装置100的黑边。
在一些实施例中，遮光结构110的材料包括白色油墨。白色油墨具有较高的反射率，从而可以有效的反射光线至显示面板20，补偿边界黑边，从而提高屏占比。
其中，遮光结构110的反射率大于或等于85%。
在一些实施例中，白色油墨可以通过丝网印刷工艺印刷至光传导层107、扩散层108和增亮层109靠近开口Op的侧面上。
请参考图4，图4为本申请实施例提供的显示装置的第三种结构示意图。本申请实施例提供的显示装置100和图3提供的显示装置100的区别在于，第一基板201包括衬底201a和设置在衬底201a上的薄膜晶体管层201b，衬底201a具有凹槽Gr，凹槽Gr和开口Op连通。本申请实施例在衬底201a上设置与开口Op连通的凹槽Gr，增大了与开口Op对应的显示面板20的光的透光率。
需要说明的是，在本申请实施例中，显示装置100可以是手机，也可以为任何具有显示功能的电子产品，包括但不限于以下类别：电视机、笔记本电脑、桌上型显示器、平板电脑、数码相机、智能手环、智能眼镜、车载显示器、医疗设备、工控设备、触摸交互终端等，本申请实施例对此不作特殊限定。
综上所述，虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
