其中，驱动单元可以采用采用2T1C、5T1C、7T1C等驱动电路中的一种。诸如第一驱动单元可以采用2T1C、5T1C、7T1C中的一种，第二驱动单元采用2T1C、5T1C、7T1C中的一种。其中，T表示薄膜晶体管，其中C表示电容。为了提高第一显示区240的透光率，设置在第一显示区240的第一驱动单元可以为比第二显示区220的主驱动单元简略的驱动电路，比如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。诸如第一驱动单元可以采用2T1C、5T1C中的一种，第二驱 动单元采用7T1C。第一驱动单元中不透光的薄膜晶体管的数量更少，第一显示区240中不透光的部分更少，可以提高第一显示区240的透光率。
请参阅图4，图4为图2所示显示装置的第一局部示意图。第二显示区220的第二像素242和第一显示区240的第一像素222的物理结构可以设置相同，或者说第二显示区220和第一显示区240可以具有相同的像素物理结构。诸如第二像素222的尺寸和第一像素242的尺寸相同，第二像素222的排布和第一像素242的排布相同。可以在同一工艺中成型。需要说明的是，第二显示区220的第二像素222和第一显示区240的第一像素242的物理结构也可以设置不相同。诸如第二像素的尺寸大于第一像素的尺寸，再比如第二像素的排布密度大于第一像素的排布密度。需要说明的是，图4仅示出显示装置20的部分像素，且图4中所示出的第一像素242排布所形成的区域与第二像素222排布所形成的区域大小大致相同。
第一显示区240可以具有多个第一像素集合244，每一个第一像素集合244可以包括多个并联连接的第一像素242。其中一个第一像素集合244可以包括至少两个第一像素242，其可以包括至少两个相同颜色的第一像素242，诸如红色像素。一个第一像素集合244也可以包括至少两个不同颜色的第一像素242，诸如红色像素和绿色像素。一个第一像素集合244中的多个第一像素242可以通过多条信号线连接在一起，该信号线可以采用透光材料。
请参阅图5，图5为图2所示显示装置的第二局部示意图。图5示出第二显示区220的多个第二驱动单元224和第一显示区240的多个第一驱动单元246。其中一个第二驱动单元224可以与一个第二像素222电性连接，一个第二驱动单元224可以驱动一个第二像素222。其中每一个第一像素集合244可以与一个第一驱动单元246电性连接，一个第一驱动单元246可以驱动一个第一像素集合244，即一个第一驱动单元246可以驱动一个第一像素集合244内的所有第一像素242。相比一个驱动单元驱动一个像素，本申请实施例可以减少第一驱动单元的个数。本申请实施例可以将第一驱动单元246设置在第一显示区240，诸如设置在第一驱动部234。由于采用较少的第一驱动单元246即可实现对第一显示区240中多个第一像素242的驱动，可以提高第一显示区240的透光率。需要说明的是，图5仅示出显示装置20的部分第二驱动单元224和部分第一驱动单元246，且图5中所示出的第一驱动单元246排布所形成的区域与第二驱动单元224排布所形成的区域大小大致相同。
本申请实施例可以将一个第一像素集合244作为第一显示区240的一个第一显示单元，即第一显示区240显示画面的最小单元。比如作为一个第一显示单元的第一像素集合244包括四个相同颜色的第一像素242、十六个相同颜色的第一像素242。再比如作为一个第一显示单元的第一像素集合244包括多个颜色不相同的第一像素242。其中，第二显示区220的多个第二像素222可以形成一个第二显示单元，或者说是第二像素单元，诸如第二显示区220的第二像素单元包括一个红像素、一个绿像素和一个蓝像素。当然，第二显示区220的第二像素单元还可以包括其他像素，诸如还包括一个白像素或一个黄像素。
本申请实施例还可以将多个第一像素集合244作为一个第一显示单元，比如三个第一像素集合244可以作为一个第一显示单元，再比如四个第一像素集合244可以作为一个透光显示单元。作为第一显示单元中的一个第一像素集合244可以包括四个相同颜色的第一像素242或十六个相同颜色的第一像素242。比如一个第一显示单元包括三个第一像素集合244，该三个第一像素集合244中的一个第一像素集合244包括四个红像素、另一个第一像素集合244包括四个绿像素、第三个第一像素集合244包括四个蓝像素。
请参阅图6，图6为图2所示显示装置中第一显示区的一个第一显示单元的第一种排布示意图。第一显示区240的一个第一显示单元216a可以包括三个第一像素集合244，可以为第一像素集合244a、第一像素集合244b和第一像素集合244c。第一像素集合244a可以包括四个红像素242(R)，第一像素集合244b可以包括四个绿像素242(G)，第一像素集合244c可以包括四个蓝像素242(B)。需要说明的是，一个第一显示单元中多个第一像素集合的排布并不限于此。
请参阅图7，图7为图2所示显示装置中第一显示区的一个第一显示单元的第二种排布示意图。第一显示区240的一个第一显示单元216b可以包括三个第一像素集合244，可以为第一像素集合244d、第一像素集合244e和第一像素集合244f。第一像素集合244d可以包括四个红像素242，第一像素集合244e可以包括四个绿像素242，第一像素集合244f可以包括四个蓝像素242。
请参阅图8，图8为图2所示显示装置中第一显示区的一个第一显示单元的第三种排布示意图。第一显示区240的一个第一显示单元216c可以包括三个第一像素集合244，可以为第一像素集合244h、第一像素集合244i和第一像素集合244j。第一像素集合244h可以包括四个红像素242，第一像素集合244i可以包括四个绿像素242，第一像素集合244j可以包括四个蓝像素242。
请参阅图9，图9为图2所示显示装置中第一显示区的一个第一显示单元的第四种排布示意图。第一显示区240的一个第一显示单元216d可以包括三个第一像素集合244，可以为第一像素集合244k、第一像素集合244m和第一像素集合244n。第一像素集合244k可以包括四个红像素242，第一像素集合244m可以包括四个绿像素242，第一像素集合244n可以包括四个蓝像素242。
可以理解的是，当第一显示区240的一个第一显示单元包括四个第一像素集合244时，四个第一像素集合244中的每一个第一像素集合244所包括的第一像素242的颜色相同，诸如一个第一像素集合244包括多个红像素、第二个第一像素集合244包括多个绿像素、第三个第一像素集合244包括多个蓝像素、第四个第一像素集合244包括多个白像素，或者第四个第一像素集合244包括多个黄像素。
其中图6至图9仅示出显示装置20的第一显示区240中一个第一显示单元的几种排布方式，本申请实施例第一显示区240的一个第一显示单元的其他排布方式也是可以的。
需要说明的是，在一些方案中，为了提高第一显示区的透光率，可以将第一显示区中的第一像素的尺寸设置大于第二显示区的第二像素，还可以将第一显示区的第一像素的排列比第二显示区中的第二像素的排列更加稀疏。从而，第一显示区的第一像素和第二显示区的第二像素具有不同的像素物理结构。实际工艺中，由于第一显示区中的第一像素和第二显示区的第二像素具有不同的像素物理结构，需采用不同的光罩(mask，或者称为掩膜板)通过一系列工艺诸如曝光、显影、清洗等形成像素结构。诸如第一显示区的第一像素需采用第一种型号的光罩通过第一组工艺成型，第二显示区的第二像素需采用第二种型号的光罩通过第二组工艺成型。不仅需要额外的光罩、工具，还会增加工艺过程，增加加工成本和复杂程度，导致成型后的像素良率降低。
而为了节省工具、工艺过程，可以在同一工艺、同一光罩等工具的情况下形成第一显示区的第一像素和第二显示区的第二像素，使得第一显示区的第一像素和第二显示区的第二像素的像素物理结构相同。然而，如果第一显示区的第一像素和第二显示区的第二像素的像素物理结构相同，且第一显示区的第一像素和第二显示区的第二像素的驱动方式相同，则第一显示区会布置过多走线和第一驱动单元，过多的走线会影响第一显示区的透光率。
基于相关方案中，为了在解决工艺过程和工艺成本的情况下，同时还可以减少第一显示区中信号线的排布，以方便第一显示区中线路的排布以及提高第一显示区的透光率，本申请实施例将第一显示区中的至少两个像素并联连接形成一个第一像素组。多个第一像素并联连接后可以连接到同一个信号线，相比每一个第一像素均连接一个信号线可以大大节省信号线的条数，便于信号线的排布，同时还可以提高第一显示区的透光率。
因此，本申请实施例通过将第一显示区中的至少两个第一像素并联连接形成一个第一像素组可以在不改变整个显示装置像素物理结构的前提下，可以在第一显示区的显示层位置改变布线以大大减少排布在第一显示区位置的信号线条数，进而以提高第一显示区的透光率。
为了进一步提高第一显示区240的透光率，可以将用于驱动第一显示区240的所有第一驱动单元的一部分设置在第一显示区240、另一部分设置在其他位置，比如第二显示区220，诸如一部分第一驱动单元设置在第一驱动部234，另一部分设置在第二驱动部232。
当然，本申请实施例还可以将用于驱动第一显示区240的所有第一驱动单元设置在其他位置，比如将所有第一驱动单元设置在第二显示区220。
需要说明的是，如果将用来驱动第一显示区240中第一像素242的第一驱动单元246布置在第二显示区220中，诸如第二驱动部232，则需要排布走线。考虑到布线会占用第一显示区240和第二显示区220连接位置的空间，如果线条太多，可能空间不够排布，就需要增加厚度来排布更多的线条。为了不额外增加布线位置的厚度，且确保第一显示区240和第二显示区220的连接位置可以有足够空间布线，可以将第一显示区240中的至少两个第一像素242并联连接形成一个第一像素集合244后连接到同一个信号线上，可以大大减少信号线的条数，减少信号线对空间的占用，可以实现将用来驱动第一显示区240中第一像素242的第一驱动单元246设置在第二显示区220中。
然而，考虑到第二显示区220为显示装置20的主要显示部分。若将用来驱动第一显示区240的第一驱动单元246全部设置在第二显示区220，会影响位于第二显示区240的第二驱动部232的设置，以及会影响第二驱动部232的布线工艺，可能会对第二显示区220显示画面的质量、效果产生影响。为此，本申请实施例为了减少第一驱动单元246对第二显示区220的影响，可以在第二显示区220和第一显示区240之间设置第三显示区，可以形成过渡，以将第一驱动单元布置在第三显示区，而降低第一驱动单元246对第二显示区220的影响。
请参阅图10，图10为本申请实施例提供的显示装置的另一结构示意图。显示装置20还可以包括第三显示区260，也可以将其称为过渡区。第三显示区260可以连接第二显示区220和第一显示区240，第三显示区260可以连接在第二显示区220和第一显示区240之间。本申请实施例第三显示区260可以将第二显示区220和第一显示区240间隔开，而不直接相连。本申请实施例第三显示区260也可以连接第二显示区220和第一显示区240的一部分，而第二显示区220和第一显示区240的另一部分也可以直接连接。第三显示区260的尺寸可以远小于第二显示区220的尺寸，第一显示区240和第三显示区260可以共同形成显示装置20的辅助显示区，在此可以将第一显示区240和第三显示区260定义为辅助显示区，或者辅显示区。
请参阅图11，图11为图10所示显示装置沿P4-P4方向的剖视图。显示层210还可以包括位于第三显示区260的第三显示部216。第三显示部216可以排布有多个第三像素，第三像素的排列方式可以为标准RGB排列、Pentile排列或Delta排列中的一种，当然，第三像素也可以采用其他排列方式。驱动层230还可以包括第三驱动部236，第三驱动部236可以设置多个驱动单元，诸如第三驱动部236设置多个第三驱动单元，一个第三驱动单元可以与一个第三像素电性连接，一个第三驱动单元可以驱动一个第三像素。第三驱动单元可以采用2T1C、5T1C、7T1C中的一种。比如第三驱动单元采用5T1C，本申请实施例第三显示区260可以采用5T1C，第一显示区240可以采用2T1C，第二显示区220可以采用7T1C。从而可以使得第二显示区220显示画面的质量高于第三显示区260显示画面的质量，且第三显示区260显示画面的质量高于第一显示区240显示画面的质量，可以使得第一显示区240和第二显示区220之间呈现过渡。
当然，第一显示区240、第二显示区220和第三显示区260的驱动方式并不限于此。诸如，第一显示区240和第三显示区260均采用5T1C，第二显示区220采用7T1C。
请参阅图12，图12为图10所示显示装置的第一局部示意图。第三显示区260的第三像素262的排布可以与第二显示区220的第二像素224的排布相同，也可以与第一显示区240的第一像素242的排布相同。比如第二显示区220、第三显示区260和第一显示区240具有相同的像素物理结构，第二显示区220、第三显示区260和第一显示区240的像素可以在同一工艺中成型。需要说明的是，第三显示区260的第三像素262的排布也可以与第二显示区220的第二像素224或第一显示区240的第一像素242的排布不同。需要说明的是，图11仅示出显示装置20的部分像素，且图11中所示出的第一像素242排布所形成的区域、第三像素262排布所形成的区域及第二像素222排布所形成的区域三者大小大致相同。
本申请实施例可以将用于驱动第一显示区240的所有第一驱动单元设置在第三显示区260，诸如将第一驱动单元设置在第三显示部236内。可以使得第一显示区240的驱动层结构无第一驱动单元，诸如第一显示区240的第一驱动部234无薄膜晶体管，可以大大提高第一显示区240的透光率。同时可以避免因在第一显示区240设置第一驱动单元而带来的其他问题，例如周期性排列的第一驱动单元会对摄像头60成像造成的衍射问题，第一驱动单元反射、折射对摄像头60成像造成的杂光问题。
需要说明的是，由于第三显示区260的设置有多个第三驱动单元，多个第三驱动单元会占用第三驱动部236的空间。本申请将第一驱动单元设置在第三驱动部236也会占用第三驱动部236的空间，而且布线也会占用第三驱动部236的空间。为了确保第一驱动单元可以设置在第三驱动部236，可以将第三驱动部236的布线设置更细，以减小单个信号线对空间的占用，以容纳更多信号线的排布。
当然，本申请实施例在不改变第三驱动部236中布线的粗细也可以将第一驱动单元设置在第三驱动部236内、且可以满足布线。减少第三显示区260的第三驱动单元个数。
请继续参阅图12，可以在第三显示区260设置多个第三像素集合264，每一个第三像素集合264可以包括至少两个并联连接的第三像素262，其可以包括至少两个相同颜色的第三像素262，诸如红色像素。一个第三像素集合264也可以包括至少两个不同颜色的第三像素262，诸如红色像素和绿色像素。一个第三像素集合264中的多个第三像素262可以通过多条信号线连接在一起。其中，一个第三像素集合264中第三像素262的个数可以多于一个第一像素集合244中第一像素242的个数，比如一个第三像素集合264包括四个第三像素262，一个第一像素集合244包括十六个第一像素242。当然，一个第三像素集合264中第三像素262的个数与一个第一像素集合244中第一像素242的个数相同也是可以的。
本申请实施例可以将一个第三像素集合264作为第三显示区260的一个第三显示单元。比如作为一个第三显示单元的第三像素集合264包括二个相同颜色的第三像素262、四个相同颜色的第三像素262。再比如作为一个第三显示单元的第三像素集合264包括多个颜色不相同的第三像素262。
本申请实施例还可以将多个第三像素集合264作为一个第三显示单元，比如三个第三像素集合264可以作为一个第三显示单元，再比如四个第三像素集合264可以作为一个第三显示单元。作为第三显示单元中的一个第三像素集合264可以包括二个相同颜色的第三像素262或四个相同颜色的第三像素262。比如一个第三显示单元包括三个第三像素集合264，该三个第三像素集合264中的一个第三像素集合264包括四个红像素、另一个第三像素集合264包括四个绿像素、第三个第三像素集合264包括四个蓝像素。关于第三显示单元包括第三像素集合264的个数以及第三显示单元中第三像素262的排布可以参阅图6至图9所示第一显示单元的结构，在此不再赘述。
可以理解的是，当第三显示区260的一个第三显示单元包括四个第三像素集合264时，四个第三像素集合264中的每一个第三像素集合264所包括的第三像素262的颜色相同，诸如一个第三像素集合264包括多个红像素、第二个第三像素集合264包括多个绿像素、第三个第三像素集合264包括多个蓝像素、第四个第三像素集合264包括多个白像素，或者第四个第三像素集合264包括多个黄像素。
请参阅图13，图13为图10所示显示装置的第二局部示意图。图13示出第二显示区220的多个第二驱动单元224、第三显示区260的多个第三驱动单元266和多个第一像素单元246。其中，第二驱动单元224可以参阅图5所示的内容，在此不再赘述。其中，多个第三驱动单元266和多个第二显示单元246位于第三显示区260，诸如设置在第三驱动部236内。
多个第三驱动单元266用于驱动第三显示区260，每一个第三驱动单元266可以与一个第三像素集合264电性连接，一个第三驱动单元266可以驱动一个第三像素集合264，即一个第三驱动单元266可以驱动一个第三像素集合264内的所有第三像素262。相比一个驱动单元驱动一个像素，本申请实施例可以减少第三驱动单元的个数，从而就可以减少第三驱动单元对第三驱动部236空间的占用，可以设置第一驱动单元246。诸如一个第三像素集合264包括四个并联连接的第三像素262，一个第三驱动单元266可以占用一个第三像素262对应的空间，或者略小于第三像素262对应的空间。因此，一个第三像 素集合264可以空余出至少三个第三像素262对应的空间，可以在该空余的空间中设置多个第一像素单元264，诸如设置三个第一驱动单元246。可以将空余的三个第三像素262与三个第一驱动单元246一一对应设置。
因此，本申请实施例可以通过对第三显示区260中至少两个第三像素262并联连接形成一个第三像素集合264，可以通过一个第三驱动单元266实现对多个第三像素262的驱动，可以在第三驱动部236留出足够的空间设置第一驱动单元246。从而就可以实现将第一显示区240中不透光的薄膜晶体管设置到不需要透过摄像头等光线采集信号的第三显示区260，而且第三显示区260的尺寸可以设置较小，且连接第一显示区240和第二显示区220，在第二显示区220显示画面未受到较大影响的情况下，第三显示区260显示画面的质量变差并不会对整个显示装置20的显示效果产生大的影响。
此外，第三显示区260中相互并联连接的第三像素262的个数可以小于第一显示区240中相互并联连接的第一像素242的个数，可以使得第一显示区240和第二显示区220之间的显示过渡更加平滑。
需要说明的是，本申请实施例第一驱动单元设置的位置并不限于第三显示区260。比如将一部分第一驱动单元设置在第三显示区260、另一部分第一驱动单元设置在第一显示区240，再比如将一部分第一驱动单元设置在第三显示区260、另一部分第一驱动单元设置在第二显示区220，还比如将第一驱动单元分为三部分分别设置在第一显示区240、第三显示区260和第二显示区220。
还需要说明的是，本申请实施例第一驱动单元设置的位置并不限于显示区域，也可以将第一驱动单元设置在显示装置20的侧边或非显示区域。
请参阅图14，图14为图10所示显示装置的第三局部示意图。显示装置20还可以包括非显示区280，驱动第一显示区240的第一驱动单元246可以设置于非显示区280。显示装置20可以为全面屏，即显示装置20的正面基本都是显示区域，从电子设备的正面看，显示装置20的正面基本等同于电子设备的显示面。但是，即使是全面屏的显示装置20，显示装置20的边缘还是会有非显示区280，非显示区280可以理解为显示装置20的黑边，黑边的宽度可以做到非常窄，如黑边宽度小于1毫米或0.5毫米等。因为第一显示区240面积小，第一显示区240内第一像素的数量也相对较少，而且第一显示区240的多个第一像素可以并联连接，驱动第一显示区240的第一驱动单元246减少，可以将第一驱动单元246设置到黑边位置，可以提高第一显示区240的透光率，又不会对第二显示区220或第三显示区260造成影响。对应第一显示区240的第一像素需要设置多个第一驱动单元246，可以将第一驱动单元246全部设置在黑边位置。
为了黑边位置可以更好的容纳所有的第一驱动单元246，可以用较简单的第一驱动单元246，例如第一驱动单元246可以采用2T1C、5T1C等驱动电路，可以使每个第一驱动单元246中薄膜晶体管的数量较少，单个第一驱动单元246需要的空间较少。还可以将第一显示区240内的第一像素分布密度设置较低，使用来驱动第一显示区240的第一驱动单元246的总数较少。需要说明的是，多个第一驱动单元246还可以一部分设置在非显示区280，一部分设置在其他位置，诸如第一显示区240或第三显示区260。
需要说明的是，本申请实施例提高第一显示区240的透光率的方式并不限于此，还可以采用其他方式。比如可以将显示装置20在第一显示区240的布线设置成透明结构，以增加第一显示区240的透光率。还比如可以在第一显示区240位置不设置偏光结构。再比如可以在将驱动第一显示区240的驱动单元采用被动驱动的方式，可以大大减少布线和驱动单元中的元器件。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。
然而，可以理解的是，由于一个驱动单元可以包括多个器件诸如多个TFT和电容。为了提高第一显示区240的透光率，不仅可以将驱动单元的整个结构设置在第一显示区240，也可以将一个驱动单元中的部分结构设置在第一显示区240外。通常一个驱动单元诸如第一驱动单元246可以包括多个TFT和一个或两个电容。诸如可以将第一驱动单元246中的至少一个TFT设置在第一显示区240外，将将电容设置在第一显示区240。具体的，可以将所有的TFT均设置在第一显示区240外，而仅将电容设置在第一 显示区240。也可以将所有的TFT中的一部分设置在第一显示区240，另一部分设置在第一显示区240外。
需要说明的是，第一驱动单元246的至少一个TFT设置在第一显示区240外，可以包括第二显示区220、第三显示区260、非显示区中的至少一个。其中，非显示区可以包括显示装置20的侧边，该侧边可以为第一显示区240的侧边，也可以为第二显示区220的侧边，当然还可以一部分为第一显示区240的侧边，一部分为第二显示区220的侧边。可以理解的是，该非显示区也可以包括上述的黑边。
请参阅图15，图15为本申请实施例提供的显示装置的局部结构示意图。显示装置20还可以包括侧边280，可以理解的是，显示装置20的侧边280也可以称为显示装置20的侧部、边侧等。该侧边280位于显示装置20的边缘位置，或者说侧边280位于显示装置20的显示区域周围的部分。显示装置20可以具有一个或多个侧边280，在此并不对侧边280的个数进行限定。
本申请实施例可以将第一显示区240的电路结构中的一部分或者全部布置在侧边280位置。诸如在侧边280上设置一个柔性电路板290，柔性电路板290可以与第一显示区240对应设置，或者说柔性电路板290设置在第一显示区240的侧边位置。当然，柔性电路板290也可以设置在第二显示区220对应的位置，或者说是柔性电路板290设置在第二显示区220的侧边位置。可以理解的是，柔性电路板290还可以一部分设置在第一显示区240的侧边位置，另一部分设置在第二显示区220的侧边位置。该柔性电路板290可以从延伸至第一显示区240内部，诸如从第一显示区240的驱动层或者说是驱动部延伸到第一显示区240的内部，以实现电路的连接。
本申请实施例可以将用于驱动第一显示区240的第一驱动单元的至少一个薄膜晶体管设置在侧边280上，第一驱动单元的薄膜晶体管可以采用该第一柔性电路板290作为载体，以用来驱动第一显示区240的第一像素。由于该柔性电路板290可以设置在第一显示区240的侧边位置或第二显示区220的侧边位置，或者柔性电路板290可以设置第一显示区240和第二显示区220的侧边位置，因此第一驱动单元的至少一个薄膜晶体管可以设置在第一显示区240的侧边或第二显示区220的侧边位置，或者第一驱动单元的至少一个薄膜晶体管设置第一显示区240和第二显示区220的侧边位置。在一些实施例中，可以将第一驱动单元的所有薄膜晶体管均设置在侧边280上。
需要说明的是，显示装置20的侧边280空间有限，尤其是显示装置20往往都比较薄，在其厚度方向的空间更是有限。因此，在显示装置20的侧边设置过多电路结构往往不易布线。因此，可以将第一驱动单元的所有薄膜晶体管中的一部分设置在侧边280，一部分设置在第一显示区240。
可以理解的是，第一驱动单元的薄膜晶体管往往分为不同的类型。诸如第一驱动单元的薄膜晶体管可以包括至少一个驱动管和至少一个控制管。其中，控制管可以与显示装置20的栅极线(或者称为扫描线)电性连接。还可以理解的是，显示装置20包括有多条栅极线和多条数据线，栅极线和数据线可以设置在显示装置20的不同层且相互交错排布，诸如栅极线呈行排布，数据线呈列排布。其中数据线和栅极线可以连接到一个驱动单元的不同位置实现配合以驱动一个像素。诸如数据线和栅极线连接到一个第一驱动单元的不同位置进行配合以驱动第一显示区240的第一像素。
本申请实施例可以将一种类型的薄膜晶体管设置在第一显示区240内，将另一种类型的薄膜晶体管设置在侧边280。诸如本申请实施例可以将第一驱动单元的所有驱动管设置在第一显示区240内，可以将一个第一驱动单元中的所有驱动管和一个第一像素对应，比如一个第一驱动单元中的所有驱动管在显示装置20的投影位于第一像素在显示装置20的投影内。可以将第一驱动单元的所有控制管设置在侧边280，诸如与第一显示区240对应侧边位置的柔性电路板290上。本申请实施例还可以将同一第一驱动单元的所有驱动管和所有电容设置在第一显示区240内，且与一个第一像素对应设置，比如一个第一驱动单元中的所有驱动管和所有电容在显示装置20的投影位于第一像素在显示装置20的投影内。
为了更加全面的理解本申请实施例的第一驱动单元的薄膜晶体管的设置，下面以第一驱动单元分别为7T1C、5T2C和2T1C为例进行说明。
请参阅图16，图16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。其中，T1为驱动管，T2为控制管，Vdata连接数据线，Vdd连接电压源，SEL为栅极线，OLED为像素，OLED为第一像素。
第一驱动单元可以包括多个薄膜晶体管(T1和T2)，该多个薄膜晶体管可以包括一个驱动管T1和一个控制管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多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。
本申请实施例可以将驱动管T1设置在第一显示区240，将控制管T2设置在第一显示区240外。第一显示区240的每个第一像素242与电源电压通过导线连接，导线长度越长，导线电阻也越大。不可避免的，电源电压会在导线上产生电压降(IR Drop)，导线的电阻值使得每一个第一驱动单元获得的电源电压不同，从而使得在相同的数据信号电压输入下，不同的第一像素242有不同的电流、亮度输出，导致整个显示装置的显示亮度不均匀，并且画面不同，第一像素的电压降也会跟着不同。第一驱动单元中的控制管主要起控制作用，对IR压降不敏感，放置在第一显示区240外，即电源电压和控制管的电压信号的IR压降即使较大，也不影响控制管的开启和关闭，对第一显示区240的色彩补偿没有影响。第一驱动单元中的驱动管T1主要起驱动第一像素242的作用，设置在第一显示区240，与第一像素242距离近，电压降相对就会小，即电源电压和到第一像素242的电压信号的电压降小，更容易对第一显示区240的色彩进行补偿。
需要说明的是，第一驱动单元中的电容Cs与驱动管T1相邻设置，即电容Cs和驱动管T1均可设置在第一显示区240，诸如驱动层的第一驱动部。
第一驱动单元还可以为5T2C，具体请参阅图17，图17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为第一像素。
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均设置在第一显示区240。
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。
第一驱动单元还可以为7T1C，具体请参阅图18，图18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与驱动管相邻设置，即电容C1和驱动管T1、T5和T6均设置在第一显示区。
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。
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均设置在第一显示区的第一驱动电路层。
因此，本申请实施例可以将用来驱动第一显示区240的一部分薄膜晶体管设置在第一显示区240内，且另一部分设置在第一显示区240外，不仅可以减少第一显示区240的薄膜晶体管个数，而且可以减少第一显示区240的布线，以大大提高第一显示区240的透光率。此外，由于近将用来驱动第一显示区240的一部分线路和一部分薄膜晶体管设置在第一显示区240外诸如显示装置20的侧边，在侧边空间不足的情况可以实现器件和线路的排布。
本申请实施例中的第二显示区220可以为主动式驱动(AMOLED)显示区，第一显示区240可以为主动式驱动显示区或被动式驱动(PMOLED)显示区。本申请实施例可以将第一显示区240设置小于第二显示区220，从而第一显示区240的显示内容相比第二显示区220的显示内容少，第一显示区240所显示的内容重要性相比第二显示区220较低。因此本申请实施例将第二显示区220采用AMOLED可以确保显示装置20的主要显示区域能够具有较高的显示效果。同时第一显示区240采用PMOLED，被动式驱动的第一显示区240只需要一个薄膜晶体管驱动，不透光的薄膜晶体管数量少，可以极大的提升第一显示区240的透光率。而且第一显示区240所显示的面积可以远小于第二显示区220所显示的面积，如若第一显示区240显示画面的质量降低也不会对显示装置20的整个显示造成较大影响。需要说明的是，第一显示区240也可以为主动式驱动，可以使得第一显示区240的显示效果与第二显示区220的显示效果接近。
本申请实施例第三显示区260可以根据需要选择主动式驱动显示区或被动式驱动显示区。因为第三显示区260的第三像素262和第一显示区240的第一像素242的物理结构一样，第三显示区260和第一显示区240可以为相同的驱动方式，诸如第三显示区260和第一显示区240可以为被动式驱动显示区。若第三显示区260的面积较大，或者为了提高第三显示区260的显示质量，可以将第三显示区260和第二显示区220采用相同的驱动显示区，诸如可以均为主动式驱动显示区。
其中，第一显示区240中的第一像素242的尺寸和形状可以根据需要设置。例如，第一像素242可以矩形，还可以为类圆形。类圆形的第一像素242可以为圆形、椭圆形或圆角矩形等。类圆形的第一像素242因为边缘为弧形过渡，可以改善第一显示区240的衍射问题。
本申请实施例可以将电子设备10的传感器诸如摄像头60设置在显示装置20的内侧，比如摄像头60的镜头朝向显示装置20的下基板270，且摄像头60与第一显示区240对应设置，或者说摄像头60位于第一显示区240位置下基板270的下方。摄像头60可以获取透过所述第一显示区240的外界光信号进行成像。本申请实施例可以将摄像头60的镜头和下基板270间隔设置，当然，也可以将摄像头60的镜头共用下基板270，比如将下基板270对应第一显示区240的位置设置成弧形结构。
为了减小摄像头60占用的电子设备10的空间，可以将摄像头60的镜头接近或邻接显示装置20的下基板270。显示装置20的下基板270主要用于承载显示装置20的其他层结构，本身不需要特别的功能。
请参阅图19，图19为本申请实施例提供的电子设备中显示装置和摄像头配合的结构示意图。为了进一步减小摄像头60对电子设备10内部空间的占用，可以在下基板270相对摄像头60设置一第一安 装孔272，摄像头60至少部分可设置于该第一安装孔272内。第一安装孔272可以为盲孔，即下基板270相对摄像头60的部分厚度小于其他部分的厚度，下基板270还是完整的基板，不影响其承载显示装置20其他层结构的作用，又能空出部分空间容纳摄像头60。第一安装孔272和摄像头60的安装方式可以根据第一安装孔272的尺寸和摄像头60的尺寸进行设置。示例性地，若第一安装孔272的空间不足以安装整个摄像头60，可以将摄像头60的镜头部分设置在第一安装孔272内。若摄像头足够小，可以将整个摄像头60设置在第一安装孔272内。
需要说明的是，该摄像头可以替换成电子设备10的其他传感器，即电子设备10的传感器的至少一部分可以设置第一安装孔272内。
请参阅图20，图20为本申请实施例提供的电子设备中显示装置和摄像头配合的另一结构示意图。因为第一显示区240的驱动层230可以不设置第一驱动单元，可以将摄像头60安装进驱动层。具体的，下基板270上开设的第一安装孔272为通孔，第一显示区240的驱动层具有相对摄像头60的第二安装孔238，第一安装孔272和第二安装孔238连通，摄像头60可以至少部分位于第二安装孔238内。例如，摄像头60的镜头位于在第一安装孔272和第二安装孔238内。第二安装孔238可以为通孔也可以为盲孔。第一安装孔272和第二安装孔238可以在显示装置20的部分层叠结构形成后再制作出来。例如，显示装置20的驱动层230、显示层210设置在下基板270上以后，对应摄像头60镜头位置利用激光等方式制作出第一安装孔272和第二安装孔238。
需要说明的是，该摄像头可以替换成电子设备10的其他传感器，即电子设备10的传感器的至少一部分可以设置第一安装孔272和第二安装孔238内。
可以理解的是，相对第一显示区240的摄像头60可以作为电子设备的前置摄像头，前置摄像头一般为镜头不能移动的摄像头，显示装置20的下基板和驱动层可以设置第一安装孔和第二安装孔，则相对第一显示区240的摄像头60可以为镜头可移动的摄像头，摄像头60的镜头可移动用于实现自动对焦等功能。需要说明的是，该摄像头60也可以为后置摄像头，即该电子设备10可以设置两个相对的显示装置20。
第一显示区240下方可以设置一个摄像头60也可以设置多个摄像头60。多个摄像头60可以为相互配合的摄像头60，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240下方除了设置摄像头以外还可以设置其他传感器。
其中本申请实施例的传感器并不限于摄像头，还可以为接近传感器、光线传感器、测距传感器、指纹识别传感器等。
本申请实施例的显示装置20并不限于第一显示区240和第二显示区220，或者第一显示区240、第二显示区220和第三显示区260。本申请实施例所限定的显示装置20也可以仅具有第一显示区240，即本申请实施例中整个显示区域中的一部分TFT可以设置在第一显示区240的外侧。从而可以提高整个显示区域的透光率，可以在显示装置20下方的任一位置设置摄像头60等传感器。
请继续参阅图1，电子设备10还可包括壳体40。壳体40可由塑料、玻璃、陶瓷、纤维复合材料、金属(例如，不锈钢、铝等)、其他合适的材料、或这些材料的任意两种或更多种的组合形成。壳体40可使用一体式配置形成，在该一体式配置中，一些或全部壳体40被加工或模制成单一结构，或者可使用多个结构(例如，内框架结构、形成外部外壳表面的一种或多种结构等)形成。壳体40可设置收纳腔以收纳电子设备10的器件诸如电池、电路板等。壳体40还可以承载显示装置20。
以上对本申请实施例提供的显示装置和电子设备进行了详细介绍。本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请。同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
