第一显示区240和第二显示区220都可以用于显示文字或图像，第一显示区240和第二显示区220可以共同显示图像，例如，第二显示区220显示预设图像的一部分，第一显示区240显示预设图像剩下的部分。第二显示区220和第一显示区240也可以显示不同的图像，例如，第二显示区220显示预设图像，第一显示区240显示任务栏图像。第二显示区220和第一显示区240都可以显示内容，显示区域完整，显示装置20的屏占比高，第二显示区220可以围绕第一显示区240，第一显示区240周缘可以都与第二显示区220邻接，即第一显示区240位于第二显示区220中间。第二显示区220也可以部分围绕透第一显示区240，第一显示区240的部分边缘与第二显示区220邻接，例如，第一显示区240位于显示装置20的边角位置或位于显示装置20的顶端中间。
请结合图3，图3为图2所示电子设备中X部分的放大示意图。显示装置20的第一显示区240包括多个第一驱动单元248和多个第一像素(图中未示出)，每一第一驱动单元用于驱动一个第一像素。多个第一像素呈矩阵排布，每一个第一驱动单元与其驱动的第一像素对应设置，如设置在第一像素正下方，可以理解的，每一个第一驱动单元的驱动管和控制管均设置在一起，且对应一个第一像素设置，多个第一驱动单元呈规则的矩阵排布。
在另外一些实施例中，请结合图4和图5，图4为图2所示电子设备中X部分的放大示意图，图5为本申请实施例提供的显示装置的第一显示区部分层叠结构示意图。显示装置20的第一显示区240也包括多个第一驱动单元248和多个第一像素246，每一第一驱动单元248用于驱动一个或多个第一像素246。
每一第一驱动单元248包括驱动管2482和控制管2484，每一第一驱动单元248的驱动管2482对应第一像素246设置，即每一第一驱动单元248的驱动管2482至少部分与一个第一像素246相对设置，多个第一驱动单元248的驱动管2482呈矩阵排布，至少两个第一驱动单元248的控制管2482聚集设置。
多个第一驱动单元248的驱动管2482呈矩阵分布，也可以理解为多个第一驱动单元248的驱动管2482均匀分布，任意两个相邻的第一驱动单元248的驱动管2482的间距相等。至少两个第一驱动单元248的控制管2484聚集设置，聚集设置且相邻的两个第一驱动单元248的控制管2484之间的间距较小，未聚集设置且相邻的两个第一驱动单元248的控制管2484之间的间距较大，多个第一驱动单元248的控制管2484没有均匀排布，未均匀分布的控制管2484掺杂在均匀分布(矩阵排布)的驱动管2482中，使得控制管2484和驱动管2482的整体排布不再是规则的矩阵排布，不规则排布的多个控制管2484和驱动管2482不会产生衍射现象或产生轻微的衍射现象。
多个第一像素呈矩阵排布，与第一像素对应设置的驱动管与呈矩阵排布。第一驱动单元的驱动管可以与一个第一像素至少部分相对设置，可以理解为第一显示区还包括驱动电路层，多个第一驱动单元位于驱动电路层中，每一第一驱动单元的驱动管位于一个第一像素在驱动电路层的正投影内或部分重叠。 可以理解的，至少两个第一驱动单元的控制管聚集设置可以为多个第一驱动单元的控制管聚集在多个地方，多个第一驱动单元的控制管包括多个聚集的地方，每一个聚集的地方可以为多个第一驱动单元(如4个或8个等)的控制管聚集。多个第一驱动单元的控制管也可以聚集设置在一个地方，即聚集的控制管全部聚集在一起。如一半的控制管聚集在所有控制管的中间位置。
显示装置20还包括栅极线(图中未示出)和数据线(图中未示出)，栅极线、数据线和第一驱动单元248配合驱动每一个第一像素246。栅极线和数据线可以设置在不同层且交错排布，例如，栅极线呈行排布，数据线呈列排布。
可以理解的是，第一驱动单元248包括至少两个薄膜晶体管，其中，薄膜晶体管的栅极与栅极线连接的为驱动管2482，其他的为控制管2484。
为了更加全面的理解本申请实施例的第一驱动单元248的驱动管2482和控制管2484的设置，下面以第一驱动单元248分别为2T1C、5T2C和7T1C为例进行说明。
请参阅图6，图6为本申请实施例提供的显示装置中第一驱动单元的第一种电路示意图。第一驱动单元可以为2T1C，第一驱动单元可以包括2个薄膜晶体管(T1和T2)，2个薄膜晶体管可以分成驱动管T1和控制管T2，每一个控制管T2的栅极与栅极线SEL电性连接。也可以理解为，每一个第一驱动单元中的2个薄膜晶体管可以分成两类，其中一类为驱动管另一类为控制管。每一个第一驱动单元中的薄膜晶体管的栅极若与栅极线SEL电性连接,则为控制管T2，每一个第一驱动单元中除了控制管T2以外的薄膜晶体管则为驱动管T1。
将驱动管T1对应第一像素设置，将至少两个第一驱动单元的控制管T2相邻设置。驱动管用于直接驱动第一像素，驱动管的电压直接影响第一像素的显示效果，驱动管与第一像素距离近，驱动管到第一像素的电压降(IR Drop)相对就会小，更容易对第一显示区的色彩进行补偿。控制管用于功能的开启和关闭，即使控制管的电压偏离部分，也不影响控制管的开启和关闭，对第一像素的显示效果没有影响。控制管不对应第一像素设置对第一像素的显示效果也没影响，因此，第一驱动单元中的驱动管对应第一像素设置，至少两个第一驱动单元的控制管相邻设置，第一显示区的多个第一驱动单元不是规则的排布，不规则排布的第一驱动单元不会产生衍射现象，或产生轻微的衍射现象。
需要说明的是，第一驱动单元中的Cs与驱动管相邻设置，即Cs和驱动管T1均对应第一像素设置。
第一驱动单元还可以为5T2C，具体请参阅图7，图7为本申请实施例提供的显示装置中第一驱动单元的第二种电路示意图。第一驱动单元中的T1、T3和T5为控制管，第一驱动单元中的T2和T4为驱动管。图中Vscan1、Vsacan2连接不同的栅极线，Vdata连接数据线，Vdd连接电压源，Vems连接发光扫描控制线，OLED为像素。
采用5T2C的第一驱动单元其基本的工作原理可以如下：
重置阶段：T1导通、T4导通、T3导通、T2导通，T5导通，电流通过T3和T4对电容C2充电，由于T5导通，OLED不发光。
阈值电压存储阶段：T1、T2、T3、T5导通，T4关断，Vdata为0。a点电压通过T3、T2、T5放电至Va＝Vth，由于T5导通，OLED不发光。其中，Vth为薄膜晶体管的阈值电压。
数据电压写入阶段：T1、T2、T5导通，T3、T4关断，灰阶数据电压跳变为正值，灰度数据通过 C1耦合到T2，此时Va＝Vth+Vdata*C1/(C1+C2)，由于T5导通，OLED不发光。
发光阶段：T2、T4导通，T1、T3、T5关断，T2驱动OLED发光，储存在C2的电压Va＝Vth+Vdata*C1/(C1+C2)保持不变，从而维持OLED在一帧内亮度不变。
需要说明的是，第一驱动单元中的电容C1与驱动管相邻设置，即电容C1和驱动管T1、T5、T6均对应第一像素设置。
第一驱动单元还可以为7T1C，具体请参阅图8，图8为本申请实施例提供的显示装置中第一驱动单元的第三种电路示意图。第一驱动单元中的T2、T3、T4和T7为控制管，第一驱动单元中的T1、T5和T6为驱动管。图中Gn-1、Gn连接不同的栅极线，DATA连接数据线，ELVDD连接一电压源，EM连接发光扫描控制线。
需要说明的是，第一驱动单元中的电容C1和C2与驱动管相邻设置，即电容C1、C2和驱动管T2、T4均对应第一像素设置。
采用7T1C的第一驱动单元其基本的工作原理可以如下：
电容放电阶段：Gn-1为低电位，T4导通，INIT为一个低电位，电容C1放电。
补偿阶段：Gn为低电位，T2和T3导通，T1的漏极和栅极短路，且Vg>Vth，T1打开，直到Vg＝Vdata-Vth。其中，Vth为薄膜晶体管的阈值电压。
发光阶段：EM为低电位，T5和T6导通，Vgs＝ELVDD-(Vdata-Vth)。
其中，T2、T3、T4和T7主要起到复位和控制，实际的驱动通路是T1、T5和T6。同时7T1C的第一驱动单元可以消除2T1C驱动电路中薄膜晶体管的Vth的离散，解决显示装置的亮度分布不均匀的问题。
请继续参阅图5，第一显示区240还包括像素定义层2942，像素定义层2942具有多个像素孔2944，每一像素孔2944内设有一第一像素246。每一第一驱动单元248包括多个驱动管2482，每一第一驱动单元248的多个驱动管2482聚集设置，且相对第一像素246设置。每一第一驱动单元248包括多个控制管2484，每一第一驱动单元248的多个控制管2484聚集设置，且相对像素定义层2942设置。
第一驱动单元248可以包括多个驱动管2482和多个控制管2484，第一驱动单元248可以为5T1C或7T1C等驱动电路。其中，每一个第一驱动单元248中的驱动管2482聚集设置，且相对第一像素246设置，也可以理解为每一个第一驱动单元248中的驱动管2482设置在第一像素246下方。对应的，每一个第一驱动单元248中的控制管2484聚集设置，且相对像素定义层2942设置，也可以理解为每一个第一驱动单元248中的控制管2484设置在像素定义层2942下方。
可以将第一驱动单元248的控制管2484聚集在一起，形成更稀疏的不透光的区域，提高第一显示区240的透光率。
第一显示区240还包括驱动电路层292，驱动电路层292包括第一驱动单元248，第一像素246在驱动电路层292的正投影覆盖驱动管2482，也可以理解为第一像素246完全遮挡第一驱动单元248的多个驱动管2482，像素定义层2942在驱动电路层292的正投影覆盖控制管2484，也可以理解为像素定义层2942完全遮挡第一驱动单元248的多个控制管2484。所有的驱动管2482都设置在第一像素246下方，所有的控制管2484都设置在像素定义层2942下方，方便排布驱动管2482和控制管2484。
请继续参阅图4，多个第一驱动单元248的驱动管2482通过沿第一方向设置的第一驱动信号线282连接；多个第一驱动单元248的控制管2484通过沿第二方向设置的第二驱动信号线284连接，第一方向和第二方向垂直。
连接驱动管2482的都为第一方向的第一驱动信号线282，连接控制管2484的都为第二方向的第二驱动信号线284，方便排布驱动信号线，而且第一驱动信号线282和第二驱动信号线284的方向不同，形成不规则的布线网络，与第二显示区220中有规律的密集的布线网络相比，不容易引起光的衍射现象。
第一方向可以理解为横向，第二方向可以为纵向，当然第一方向也可以为纵向，第二方向为横向。横向可以理解为显示装置20的宽度方向，纵向可以为显示装置20的长度方向。
请参阅图9，图9为本申请实施例提供的显示装置的第一显示区的部分结构示意图。显示装置20还包括第一驱动芯片260，第一驱动信号线282通过沿第二方向设置的第三驱动信号线286与第一驱动芯片260连接。第一驱动芯片260用于驱动第一显示区240显示图像，驱动管2482先后通过第一方向的第一驱动信号线282、第二方向的第三驱动信号线286与第一驱动芯片260连接，同时，第一驱动芯片260还通过第二方向的第二驱动信号线284与控制管2484连接。第一驱动芯片260设置在第一显示区240一侧，通过第二方向的第二驱动信号线284和第三驱动信号线286，以及第一方向的第一驱动信号线282，可以方便控制所有的驱动管2482和控制管2484。
请参阅图10，图10为本申请实施例提供的显示装置的第一显示区部分第一驱动电路的第二种结构示意图。其中，第三驱动信号线与第二驱动信号线284可以相邻设置。将纵向走线聚集设置，可以将驱动信号线网络稀疏化，减弱光的衍射问题。其中，第三驱动信号线可以和第二驱动信号线284汇聚形成更大的信号线。
第二显示区的驱动信号线排布方式是有规律的，密集的网络，会引起光的衍射现象。而第一显示区中连接驱动管2482的第一驱动信号线282为横向走线，连接控制管2484的第二驱动信号线284为纵向走线，同时将连接第一驱动信号线282的第三驱动信号线和第二驱动信号线284汇集成一个大的纵向走线，从而将走线网络稀疏化，减弱光的衍射问题。
需要说明的是，第二显示区的驱动信号线排布可以为有规律的密集的网络，也可以为无规律的稀疏的网络，例如，第二显示区的驱动信号线排布与第一显示区的驱动信号线排布类似。
结合图11和图12，图11为本申请实施例提供的显示装置的第一显示区中部分第一像素的第一种结构示意图，图12为本申请实施例提供的显示装置的第一显示区中部分第一驱动单元的第三种结构示意图。

需要说明的是，当第一像素的排列方式为标准RGB排列或Delta排列时，一个像素单元包括R、G、B三个不同颜色的第一像素，驱动集合对应包括三个第一驱动单元，如图15所示。此外，像素单元242还可以包括R、G、B、W四个不同颜色的第一像素246，或者包括R、G、B、Y四个不同颜色的第一像素246等，驱动集合244对应的包括四个第一驱动单元248。

公共电极层295上还可以设置平坦化层296，第一像素设置在像素孔后，第一像素并未填满像素孔，公共电极层295设置在第一像素上后，会出现凹槽，平坦化层296可以将凹槽填平，并覆盖整层发光层294，用以保护发光层294等。
在平坦化层296上还可以设置触控层297，触控层297可以用于检测用户触控操作。
在触控层297上还可以设置偏光片(图中未示出)，偏光片可以用于防止内部光线透射出去，防止用户看到内部的驱动单元等元件。触控层297和偏光片可以贴合在一起，然后再设置在平坦化层296上。
需要说明的是，在其他一些实施例中，可以根据需要增加或减少部分结构，本申请实施例在此不做限定。例如，可以减少触控层297、偏光片中的至少一项。又例如，可以在平坦化层296和触控层297之间增加一层保护层，保护层可以采用与基板291一样的材料。
第一显示区240内各层结构中除了驱动电路层292都采用透光材料，以提高第一显示区240的透光率。例如，第一显示区240的基板291、像素定义层2942、公共电极层295、平坦化层296、触控层297都可以采用透光材料制成，阳极层293中的驱动信号线可以采用ITO或纳米银等透光材料制。驱动电路层292的薄膜晶体管(TFT)无法采用透光材料，驱动电路层292中除了TFT其他部分也可以采用透光材料。可以理解的是，通过提高材料的透光率以及改变布线的排布以提高第一显示区240的方案均在本申请的范围内。
需要说明的是，第二显示区可以采用和第一显示区类似的层叠结构，具体可参阅上述实施例，在此不再赘述。第二显示区的基板、像素定义层、公共电极层、平坦化层、触控层等中的至少一项可以和第一显示区采用一样的透光材料，示例性地，基板可以采用玻璃或树脂等透光材料。第二显示区的基板、 像素定义层、公共电极层、平坦化层、触控层等中的至少一项可以和第一显示区采用不同的材料，例如，第二显示区的阳极层中的驱动信号线可以采用钼、钼铝钼、Ag等金属或合金材料，第二显示区金属阳极可以采用金属材料，比如Mg、Ag、Al。第二显示区的公共电极层可以采用Mg、Ag等材料。第二显示区的公共电极层和第一显示区的公共电极层边缘处是相连的，共同构成一个完整的公共电极层。
第二显示区的发光层包括多个第二像素，第二像素的材料可以和第一像素相同，透光率也相同。第一像素的材料也可以和第二像素不同，以实现第一像素的透光率大于第二像素的透光率。
为了提高第一显示区的透光率，可以设置第一显示区的第一像素的尺寸大于第二像素的尺寸，第一显示区的第一像素的尺寸大于第二像素的尺寸，第一像素之间的间距和第一像素的尺寸正相关，即，第一像素的尺寸越大，第一像素之间的间隔距离也越大，因此，第一显示区的第一像素的分布密度小于第二显示区第二像素的分布密度，第一像素之间的像素定义层的透光率大于第一像素的透光率，因此，第一像素的尺寸越大，第一显示区的透光率越高。示例性的，第二显示区的第二像素可以达到400ppi以上，第一显示区的第一像素的尺寸可以为第二像素的四倍，第一显示区的第一像素可以为200ppi。
为了提高第一显示区的透光率，还可以设置第一像素的分布密度小于第二像素的分布密度。第一显示区的第一像素的尺寸与第二像素的尺寸相同，增大第一像素之间的间隔距离，使第一像素的分布密度小于第二像素的分布密度，第一像素之间的像素定义层的透光率大于第一像素的透光率，因此，第一像素的分布密度越小，第一像素之间的间隔距离越大，第一显示区的透光率越高。示例性的，第二显示区的第二像素可以达到400ppi以上，第一像素之间的间距远大于第二像素之间的间距，第一显示区的第一像素可以为200ppi。
为了提高第一显示区的透光率，设置在第一显示区的第一驱动单元可以为简略的驱动电路。具体的，第二显示区包括多个第二驱动单元，一个第二驱动单元驱动一个第二像素。第一显示区的第一驱动单元可以为比第二显示区的第二驱动单元更简略的驱动电路，即第一驱动单元包括的薄膜晶体管的数量少于第二驱动单元的薄膜晶体管的数量。因为，薄膜晶体管不透光，第一驱动单元中不透光的薄膜晶体管的数量较少，其占据的面积也较少，驱动电路层不透光的区域也较少，驱动电路层可透光的区域的占比也较高，可以提高第一显示区的透光率。例如，第二驱动单元为7T1C驱动电路，第一驱动单元可以为5T1C或2T1C等驱动电路。
为了提高第一显示区的透光率，还可以设置第一驱动单元的分布密度小于第二驱动单元的分布密度。一个第一驱动单元可以驱动多个第一像素，一个第二驱动单元驱动一个第二像素。第二显示区中，一个第二驱动单元驱动一个第二像素。第一显示区中，一个第一驱动单元驱动多个第一像素，可以减少第一驱动单元的数量，减小第一驱动单元的分布密度，单位面积内的第一驱动单元的数量小于单位面积内第二驱动单元的数量，相对于第二显示区，可以提高第一显示区的透光率。其中，第一像素和第二像素的物理结构可以相同，第一显示区和第二显示区的发光层可以在同一工序中形成，第一显示区和第二显示区的发光层没有区别。第一像素和第二像素的物理结构相同可以理解为第一像素和第二像素的尺寸大小相同、分布密度相同、排列方式相同等。排列方式可以为标准RGB排列、Pentile排列或Delta排列中的一项。
一个第一驱动单元驱动的多个第一像素可以并联连接也可以串联连接。需要说明的是，串联连接需 要较大的驱动电压，并联连接的第一驱动单元的驱动电压和第二驱动单元的驱动单元相近，而驱动单元的驱动电压升高较难，并联连接形成的第一像素集合中第一像素的数量可以多于串联连接形成的第一像素集合。多个第一像素并联可以通过在发光层中的第一像素并联连接实现，也可以通过阳极层中的金属阳极并联连接实现。
需要说明的是，为了提高第一显示区的透光率的可以将上述多个实施例的方式结合使用，即采用增大第一像素的尺寸、减小第一像素的分布密度、第一驱动单元采用更简略的驱动电路、减小第一驱动单元的分布密度中的至少两种。
显示装置还包括偏光片，偏光片对应第一显示区可以具有第一偏光部，第一偏光部可以为通孔或透光材料。例如，先对应第一显示区设置一通孔，然后在通孔内填充透明材料形成第一偏光部。又例如，先对应第一显示区设置一通孔，然后在通孔内填充高透光低偏光性材料形成第一偏光部，使第一偏光部既可以实现高透光率的功能，又可以实现防止光线反射出去，让用户看到内部结构的功能。
第一显示区的层叠结构还可以为其他结构，本申请实施例并不对此进行限定。示例性的，在其他一些实施例中，请参阅图17，图17为本申请实施例提供的显示装置中第一显示区的另一层叠结构示意图。本实施例中第一显示区的层叠结构与上述实施例的主要区别在于驱动电路层和阳极层。第一显示区的第一驱动单元的薄膜晶体管的源极和漏极位于同一层，源极位于栅极和发光层之间。
阳极层293部分设置在驱动电路层292上，阳极层293包括第一阳极层2932、第一绝缘层2934和第二阳极层2936，第一绝缘层2934设置在第一阳极层2932和第二阳极层2936之间，用以将第一阳极层2932和第二阳极层2936分隔并绝缘，第一阳极层2932包括第一信号线(栅极线)，第二阳极层2936包括第二信号线(数据线)，第一信号线和第二信号线位于不同层且可以垂直设置，第一信号线和第二信号线分别与第一驱动单元电性连接，显示装置的第一驱动芯片通过第一信号线和第二信号线控制第一驱动单元。第一信号线可以与第一驱动单元中薄膜晶体管的栅极位于同一层，第二信号线可以通过过孔内的导线与第一驱动单元中薄膜晶体管的漏极连接。阳极层293还可以包括金属阳极层2938，金属阳极层2938相邻发光层294，金属阳极层2938的金属阳极和发光层294的第一像素直接邻接并电性连接，金属阳极层2938和第一驱动单元中的源极之间具有第二绝缘层2939，金属阳极可以通过像素过孔与第二驱动单元228的源极电性连接。遮光块280设置在金属阳极层2938和第二阳极层2936之间的第二绝缘层2939。
需要说明的是，显示装置可以包括第一显示区和第二显示区，显示装置也可以仅包括第一显示区。
可以理解的是，上述任意一个实施例中，第一显示区中的第一像素的尺寸和形状可以根据需要设置。例如，第一像素可以矩形，还可以为类圆形。类圆形的第一像素可以为圆形、椭圆形或圆角矩形等。类圆形的第一像素因为边缘为弧形过渡，可以改善第一显示区的衍射问题。
显示装置可以呈规则形状，如矩形、圆角矩形或圆形。当然，在一些其它可能的实施例中，显示装置也可以呈非规则形状，本申请实施例对此不作限定。
第一显示区下方可以设置一个摄像头也可以设置多个摄像头。多个摄像头可以为相互配合的摄像头，如两个相同的摄像头、一个普通摄像头和一个虚化摄像头或黑白摄像头等，第一显示区下方除了设置摄像头以外还可以设置其他功能器件，如接近传感器、光线传感器、测距传感器、指纹识别传感器等。
为了更加全面的理解本申请实施例的电子设备。下面对电子设备的结构作进一步说明。请继续参阅图1，电子设备10还包括壳体40和摄像头60。

电子设备还可以包括电路板、电池和中板。边框420围绕中板设置，其中，边框420可以与中板形成电子设备10的中框。中板和边框420在中板两侧各形成一个容纳腔，其中一个容纳腔用于容置显示装置20，另一个容纳腔用于容置电路板、电池和电子设备10的其他电子元件或功能组件。
其中，中板可以为薄板状或薄片状的结构，也可以为中空的框体结构。中框用于为电子设备10中的电子元件或功能组件提供支撑作用，以将电子设备10中的电子元件、功能组件安装到一起。电子设备10的摄像头60、受话器、电池等功能组件都可以安装到中框或电路板上以进行固定。可以理解的，中框的材质可以包括金属或塑胶等。
电路板可以安装在中框上。电路板可以为电子设备10的主板。其中，电路板上可以集成有麦克风、扬声器、受话器、耳机接口、加速度传感器、陀螺仪以及处理器等功能组件中的一个或多个。同时，显示装置20可以电连接至电路板，以通过电路板上的处理器对显示装置20的显示进行控制。显示装置20和摄像头60可以均与处理器电性连接；当处理器接收到拍摄指令时，处理器控制第一显示区240关闭显示，并控制摄像头60透过第一显示区240采集图像；当处理器未接收到拍摄指令，且接收到显示图像指令时，处理器控制第二显示区220和第一显示区240共同显示图像。
电池可以安装在中框上。同时，电池电连接至电路板，以实现电池为电子设备10供电。其中，电路板上可以设置有电源管理电路。电源管理电路用于将电池提供的电压分配到电子设备10中的各个电子元件。
应当理解的是，在本文中提及的“多个”是指是两个或两个以上。
