具体实施例
为了使本申请的目的、技术方案及优点更加清楚，以下结合附图及实施例，对本申请进行详细说明。此处所描述的具体实施例仅用以解释本申请， 不应当被认为是对本申请的限制。
正如背景技术所述，传统的电子设备如手机、平板电脑等，由于需要集成诸如前置摄像头、听筒以及红外感应元件等，故而可通过在显示屏上开槽(Notch)，在开槽区域设置摄像头、听筒以及红外感应元件等。但开槽区域并不用来显示画面，如现有技术中的“刘海屏”，或者采用在屏幕上开孔的方式，对于实现摄像功能的电子设备来说，外界光线可通过屏幕上的开孔处进入位于屏幕下方的感光元件。但是这些电子设备均不是真正意义上的全面屏，并不能在整个屏幕的各个区域均进行显示，如在摄像头区域不能显示画面。
针对上述问题，技术人员研发了一种显示屏，其通过在在开槽区域设置透明显示面板的方式来实现电子设备的全面屏显示。由于开槽区域通常设置在显示屏之中，从而使得位于开槽区域左侧的信号线无法与位于开槽区域右侧的信号线进行连接。如果驱动芯片(IC)在位于开槽区域的左侧，则相当于开槽区域右侧的信号线没有驱动IC与之连接，进而导致显示异常。由于开槽区域设置有透明显示面板，因此可采用的做法是在开槽区域的相对两侧均设置驱动IC，以确保两侧的信号线都能够正确与驱动IC连接，进而使得显示屏正常显示。两侧分别设置驱动IC，会造成成本的浪费，且两个驱动IC需要同步，可控性较差。并且由于需要在两侧均放置驱动IC，两侧的边框都较大，不利于实现全面屏正常显示。
本申请一实施例提供了一种显示屏，其能够很好地解决上述问题。图1为一实施例中的显示屏的结构示意图。参见图1，该显示屏具有第一显示区AA1和第二显示区AA2。第二显示区AA2至少部分区域完全被第一显示区AA1所包围。第二显示区AA2的形状可以为圆形、椭圆形、矩形或者其他不规则图形。在一实施例中，第二显示区AA2可以设置在显示屏的顶部中间区域，且第二显示区AA2为矩形，从而与第一显示区AA1存在三面接触，如图1所示。第二显示区AA2也可以设置在第一显示区AA1的左侧中间区域，或者右侧中间区域。在另一实施例中，第二显示区AA2还可以设置在第一显 示区AA1的内部，从而使得第二显示区AA2完全被第一显示区AA1所包围。在图1中，第一显示区AA1和第二显示区AA2的数量均为一个，在其他的实施例中，第一显示区AA1和第二显示区AA2的数量均可以为两个或者两个以上。第一显示区AA1和第二显示区AA2均用于显示动态或者静态画面。
在本实施例中，第一显示区AA1内的信号线被第二显示区AA2间隔。比如，被间隔的信号线可以为数据线或者扫描线中的其中一种，具体可以根据显示区的相对位置关系以及驱动电路等等设置情况进行确定。被第二显示区AA2间隔的信号线中，位于第二显示区AA2一侧的为第一信号线114a，位于第二显示区AA2的另一侧的为第二信号线114b。第二显示区AA2中设置有多条信号连接线112。信号连接线112的数量与被第二显示区AA2所间隔的信号线的数量相同。信号连接线112贯穿第二显示区AA2的两侧，并分别连通第一信号线114a和第二信号114b，以防止出现显示异常。
上述显示屏具有均用于进行显示动态或者静态画面的第一显示区AA1和第二显示区AA2，可以真正实现全面屏显示。并且在第二显示区AA2中设置有信号连接线112，连接第一显示区中被间隔的信号线(如数据线或者扫描线等)，从而保证第一显示区AA1中位于第二显示区AA2相对两侧的信号线能够连通，防止出现显示异常。并且，通过信号连接线112来连通位于第二显示区AA2两侧的第一信号线114a和第二信号线114b，使得在一侧设置驱动电路(如驱动IC)130即可实现对第一显示区中的信号线的驱动。相对于传统的做法而言可以节省成本且无需双侧设置较大的边框，有利于实现全面屏显示。
在本实施例中，驱动电路130设置在第二显示区AA2的左侧，则对应的第一信号线114a为第一数据线，第二信号线114b为第二数据线，此时信号连接线112为数据连接线，用于将第二显示区AA2两侧的第一数据线和第二数据线进行连接。信号连接线112的数量由第二显示区AA2经过的像素行/列来确定。在另一实施例中，当驱动电路130设置在第二显示区AA2的右侧时，被间隔的信号线为数据线。当驱动电路130设置在第二显示区AA2的上 侧或者下侧时，被间隔的信号线为扫描线，对应的信号连接线112为扫描连接线。在其他的实施例中，第二显示区AA2设置在第一显示区AA1内部，第二显示面板120的四面均与第一显示面板110连接。此时，第一信号线114a同时包括第一扫描线和第二数据线，第二信号线114b则同时包括第一扫描线和第二扫描线。同样的，信号连接线112则同样包括扫描连接线和数据连接线。扫描连接线用于将第一扫描线和第二扫描线进行连接，数据连接线则用于将第一数据线和第二数据线进行连接，以确保显示屏的正常显示。
在一实施例中，第二显示区AA2包括第一子显示区AA22和第二子显示区AA24，如图2所示。第二子显示区AA24下方可设置感光器件。在本实施例中，第二子显示区AA24的个数为两个，且均由第一子显示区AA22所包围。在其他的实施例中，第二子显示区AA24的数量也可以设置为一个。第二子显示区AA24的数量可以根据显示终端中的感光器件的位置设置来确定。比如，显示终端的前置摄像头采用双摄像头时，可以设置两个第二子显示区AA24，每个第二子显示区AA24对应一个摄像头。在本实施例中，信号连接线112设置于第一子显示区AA22，从而可以避开摄像头等感光器件所在的区域，不会对摄像头等感光器件的工作产生影响。
在一实施例中，显示屏包括第一显示面板110和第二显示面板120。第一显示面板110设置于第一显示区AA1；第二显示面板120设置于所述第二显示区AA2。第一显示面板110和第二显示面板120可以分别进行制作后进行拼接，也可以同时制作形成一体化屏。此时，第一显示面板110和第二显示面板120共用一个基板。
在一实施例中，第一显示面板110为AMOLED显示面板，第二显示面板120为PMOLED显示面板。图3为一实施例中的第二显示面板的剖视图。在本实施例中，仅仅给出了涉及的结构层，而省略了或者简化了其他图层。参见图3，第二显示面板120包括基板210、信号连接线112、信号屏蔽层230、第一电极层240以及像素定义层250。信号连接线112设置在基板210上。在一实施例中，信号屏蔽层230设置在信号连接线112上且覆盖信号连接线 112。第一电极层240形成于信号屏蔽层230上。像素定义层250则形成在第一电极层240上。具体地，信号连接线112设置在像素定义层250的下方，且避开摄像头930等感光器件所在的区域。通过将信号连接线112设置在像素定义层250下方且避开摄像头所在区域，可以避免信号连接线112对发光区域以及摄像头正常工作的干扰。并且，通过在信号连接线112和第一电极层240之间形成信号屏蔽层230，可以确保信号连接线112不会对第一电极层240产生信号干扰。
在一实施例中，信号连接线112位于第一电极层240和基板210之间。也即，信号连接线112设置在第一电极层240下方，从而可以减小对第一电极层240的工作影响。此时，第一电极层240为阳极层。在另一实施例中，信号连接线112也可以设置于第一电极层240上方，且位于像素定义层下方。当信号连接线112设置在第一电极层240上方时，此时第一电极层240为阴极层，从而避免信号连接下112对其正常的工作产生干扰。
在一实施例中，基板210包括玻璃基板212和形成在玻璃基板212上方的柔性基板214。通过增设柔性基板214，可以确保基板210具有一定的弯折性能。
在一实施例中，第一子显示区AA22的像素定义层由不透光材料(如阻光或者吸光材料)制成，例如黑色的有机胶等。由于第一子显示区AA22并不需要设置摄像头，因此对该区域的透光率要求较低。此时，信号连接线112的材料为金属或者透明金属氧化物。例如，当信号连接线112的材料采用透明金属氧化物时，可以采用氧化铟锡(ITO)、氧化铟锌(IZO)、掺杂银的氧化铟锡(Ag+ITO)或者掺杂银的氧化铟锌(Ag+IZO)等。通过将第一子显示区AA22的像素定义层250设置为不透光，以牺牲一定的面板透光率来确保经过第一子显示区AA22的信号连接线112不可见，提高显示屏的视觉效果。
在一实施例中，第二显示区AA2的像素定义层250由透光材料制成。此时，信号连接线112的材料为透明金属氧化物。通过将第二显示区AA2的像 素定义层250设置为透光材料，可以确保显示屏具有较好的透光率，确保设置于下方的摄像头930等感光器件的正常工作。通过将信号连接线112的材料设置为透明的金属氧化物时，可以确保在第二显示面板120为透明显示面板时，其不会对显示面板的透明度产生影响。
在一实施例中，参考图4，各信号连接线112在第二子显示区内AA24相互平行设置。由于信号连接线112需要避开显示面板中的发光区域(对应于像素定义层250的像素开口252)，因此其均沿像素的点阵结构进行布线，故无论像素定义层250是透光还是非透光材料，其均可以在第二子显示区AA24内相互平行设置，从而可以降低各信号连接线112之间的相互干扰。在本实施例中，由于需要避开用于设置感光器件的区域，从而使得信号连接线112在部分区域并不是直线状态，而是会出现弯折的状况。
在一实施例中，所述显示屏包括多个导电材料层，信号连接线112可以在第二子显示区AA24分布于不同的导电材料层，并通过接触孔(例如金属接触孔)连接，从而实现跨层设置。由于第二子显示区AA24在设置信号连接线112的同时，还需要设置有其他的走线，从而使得该区域内的布线较多。为确保信号连接线112不影响其他的布线，从而可以将信号连接线114通过金属桥跨层设置。
请参阅图3，在一实施例中，信号屏蔽层230包括绝缘层232。绝缘层232形成于信号连接线112和第一电极层240之间，用于实现二者之间的电气绝缘，避免二者的信号产生串扰。
在一实施例中，信号屏蔽层240还包括隔离结构234和平坦化层236。隔离结构234形成于绝缘层232的上方。平坦化层236形成于隔离结构234上方且覆盖隔离结构234，如图3所示。在本实施例中，隔离结构234为导电材料，以通电实现信号连接线112和第一电机层240之间的电磁隔离。隔离结构234同样可以采用金属、透明金属氧化物等。在一实施例中，为使得整个显示屏能够实现柔性屏，可以将隔离结构234设置为石墨烯或者纳米材料等。由于隔离结构234仅仅用于隔离，并不需要进行信号的传输，因此可 以采用石墨烯或者纳米材料等高柔性且高电阻的材料。但是显示屏中原有的信号线需要传递信号，对线路电阻会有一定的要求，从而仍采用金属或者金属氧化物等低电阻的材料。在一实施例中，隔离结构234与显示屏的地线或者参考线(REF)相连，以确保信号连接线112和第一电极层240之间的电磁隔离，达到防止串扰的效果。
在本实施例中，隔离结构234上形成于有屏蔽图形。屏蔽图形在基板210上的投影至少应该能够覆盖信号连接线112在基板210上的投影和第二显示面板的第一电极830在基板210的投影之间的交叠区域，也即套刻区域。在其他的实施例中，也可以使得屏蔽图形在基板210上的投影覆盖住信号连接线在基板210的投影或者覆盖住第一电极830在基板210的投影。
如图5所示，在一实施例中，信号连接线112和第一电极层240中的第一电极830的形状为多个相接的弧形。具体地，在第一电极830的延伸方向上，多个相接的弧形的宽度持续变化或者间断变化。宽度连续变化是指在多个相接的弧形上任意两个相邻位置处的宽度不相同。宽度间断变化是指在第一电极830上存在部分区域内相邻两个位置的宽度相同，而在部分区域内相邻两个位置的宽度不相同。通过将第二显示面板120中的第一电极830以及信号连接线112设计为多个相接的弧形，从而使得外部光线经过第一电极830时，在第一电极830的不同位置处产生的衍射条纹的位置不同。不同位置处的衍射条纹相互抵消，从而可以有效减弱衍射效应，进而确保摄像头设置在第二显示面板120下方时，拍摄得到的图形具有较高的清晰度。在一实施例中，第一电极层240可以为阳极层。
在一实施例中，像素定义层250中形成有像素开口252。每个像素开口252对应一个发光结构。各像素开口的形状可置圆形、椭圆形、哑铃形或者葫芦形，具体可以参考图4和图6。通过将各子像素设置为圆形、椭圆形、哑铃形或者葫芦形，同样可以弱化衍射效应。并且，圆形、椭圆形、哑铃形或者葫芦形可在最大限度上扩大各个子像素的面积，进一步提高透光率。
在一实施例中，第一显示面板110为AMOLED显示面板，第二显示面 板120为AMOLED显示面板或者类AMOLED显示面板。类AMOLED显示面板是指其像素电路仅包含一个开关元件(即驱动TFT)，而无电容结构。类AMOLED显示面板的其他结构与AMOLED显示面板相同。下面以第二显示面板120为类AMOLED显示面板为例进行说明。
图7为一实施例中的类AMOLED显示面板的剖视图。该类AMOLED显示面板包括基板810以及设置于基板810上的像素电路820(也即TFT阵列)。像素电路820上设置有第一电极层。第一电极层包括多个第一电极830。第一电极830与像素电路820一一对应。此处的第一电极830为阳极。类AMOLED显示面板还包括像素定义层840，设置于第一电极830上。像素定义层840上具有多个开口，开口内设置有发光结构层850，以形成多个子像素，子像素与第一电极830一一对应。发光结构层850的上方设置有第二电极860，第二电极860为阴极，该阴极为面电极，也就是由整面的电极材料形成的整面电极。像素电路840中设置有扫描线、数据线和TFT开关元件。扫描线和数据线均与TFT开关元件连接。扫描线控制TFT开关元件的开启和关闭，数据线在像素开启时，为第一电极830提供驱动电流，以控制子像素发光。
在本实施例中，信号连接线112设置在像素定义层840下方且设置于像素电路下方，从而使得二者在空间上相互错开，减少相互之间的串扰。在其他的实施例中，信号连接线112设置在像素定义层840的下方，且与像素定义层840中的导电层在同一工艺步骤中完成，从而无需再在制备时额外增加工序，不会增加制备的复杂度。在另一实施例中，信号连接线112设置在像素定义层840的下方，且位于像素电路和第一电极层830之间。
在一实施例中，基板810可以为刚性基板，如玻璃基板、石英基板或者塑料基板等透明基板；基板810也可为柔性基板，如PI薄膜等，以提高器件的透明度。光结构层850可以是OLED(Organic Light-Emitting Diode，有机发光二极管)。
图8为一实施例中的像素电路820的电路原理图。与传统的AMOLED 显示面板的像素电路不同，像素电路820仅包括开关器件，而不包括存储电容等元件，从而形成无电容结构。在本实施例中，像素电路820包括一个开关器件。开关器件与第一电极830一一对应设置，即一个子像素对应一个开关器件。开关器件包括第一端2a、第二端2b和控制端2c，详见后续具体介绍。扫描线与开关器件的控制端2c连接，数据线连接开关器件的第一端2a，第一电极830连接开关器件的第二端2b。如图8所示。上述像素电路820中，通过数据线连接开关元件的第一端2a，扫描线连接开关元件的控制端2c，能够将像素电路820中的开关元件减少至一个，大大降低扫描线的负载电流以及数据线的负载电流。
上述显示面板中扫描线控制像素电路820的开启和关闭，仅需提供像素电路820中的开关元件所需的开关电压，不需要输入发光结构(OLED)的电流，大大降低扫描线的负载电流，使得扫描线可以采用ITO等透光材料制作。并且，数据线在像素电路820开启时，为阳极提供驱动电流，控制子像素发光，数据线在每一时刻只需供应一个子像素的驱动电流，数据线的负载也很小。因此，数据线也可以采用ITO等透光材料，从而提高了显示屏的透光率。多个子像素共用面电极(阴极)，每一时刻一行子像素的电流由整面阴极提供，对阴极的导电性要求大幅度降低，可以采用高透明电极，提高了透明度，提高了屏幕整体的一致性，并且不需要负性光刻胶分开阴极。
在一实施例中，第一电极830可以为设置为圆形、椭圆形、哑铃形或者葫芦形，具体可以参考图6。通过将第一电极830设置为圆形、椭圆形、哑铃形或者葫芦形，同样可以弱化衍射效应。在一实施例中，像素定义层640中的像素开口的形状为圆形、椭圆形、哑铃形或者葫芦形，如图6，从而同样可以弱化衍射效应。在一实施例中，扫描线和数据线等信号线可以采用图5所示的多个相接的弧形，从而达到改善衍射的效果。
在本实施例中，像素定义层840以及信号连接线112的材料以及排布情况可以如前述实施例中的进行设置，此处不赘述。
在一实施例中，第二显示面板120可以为透明或者半透半反式的显示面 板。第二显示面板120的透明可以通过采用透光率较好的各层材料来实现。例如，各层材料都具有膜层，各膜层均采用透光率大于90％的材料，从而使得整个显示面板的透光率可以在70％以上。进一步的，各膜层均采用透光率大于95％的材料，进一步提高显示面板的透光率，甚至使得整个显示面板的透光率在80％以上。具体地，可以将信号走线设置为ITO、IZO、Ag+ITO或者Ag+IZO等，绝缘层材料优选SiO 2，SiN x以及Al 2O 3等，像素定义层则采用高透光材料。
可以理解，第二显示面板120的透明还可以采用其他技术手段实现。透明或者半透半反式的显示面板处于工作状态时能够正常显示画面，而当该显示面板处于其他功能需求状态时，外部光线可以透过该显示面板照射到置于该显示面板之下的感光器件等。
通过将第二显示面板120设置为透明或者半透半反式的显示面板，从而使得摄像头等感光器件可以设置在第二显示面板120下方。可以理解，第二显示区AA2在感光器件不工作时，可以正常进行动态或者静态画面显示，而在感光器件工作时，第二显示区AA2随着整体显示屏的显示内容的变化而变化，如显示正在拍摄的外部图像，或者第二显示区AA2也可以处于不显示状态，从而进一步确保感光器件能够透过该第二显示区AA2的第二显示面板120进行光线采集。在其他的实施例中，第一显示区AA1和第二显示区AA2的透光率也可以相同，也即第一显示面板110与第二显示面板120的透光率可以相同，从而使得整个显示屏具有较好的透光均一性，确保显示屏具有较好的显示效果。
本申请一实施例还提供一种显示终端。图9为一实施例中的显示终端的结构示意图。该显示终端包括设备本体910和显示屏920。显示屏920设置在设备本体910上，且与该设备本体910相互连接。其中，显示屏920可以采用前述任一实施例中的显示屏，用以显示静态或者动态画面。
图10为一实施例中的设备本体910的结构示意图。在本实施例中，设备本体910上可设有开槽区912和非开槽区914。在开槽区912中可设置有诸 如摄像头930以及光传感器等感光器件。此时，显示屏920的第二显示区AA2对应于开槽区914贴合在一起，以使得上述的诸如摄像头930及光传感器等感光器件能够透过该第二显示区AA2对外部光线进行采集等操作。
在一实施例中，为了提高透光率，在第二显示区AA2可以不设置偏光片，也即第二显示面板120中不设置偏光片。并且由于第二显示区AA2中的第二显示面板120能够有效改善外部光线透射该第二显示区AA2所产生的衍射现象，从而可有效提升显示终端上摄像头930所拍摄图像的质量，避免因衍射而导致所拍摄的图像失真，同时也能提升光传感器感测外部光线的精准度和敏感度。
上述显示终端可以为手机、平板、掌上电脑、ipod等数码设备。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
