为使本申请的上述目的、特征和优点能够更为明显易懂，下面结合附图对本申请的具体实施例做详细的说明。
由于显示屏幕上方通常会预留一部分区域用于安装摄像头、传感器、听筒等元件，容易影响屏幕的整体一致性。
图1是本申请一实施例中的OLED阵列基板的俯视图；图2是沿着图1中的AA直线的剖视图。
参照图1与图2所示，该OLED阵列基板1，包括：显示区10，显示区10包括非透明显示区10a与透明显示区10b。
非透明显示区10a包括阵列排布的第一OLED子像素11，在垂直于OLED阵列基板1所在平面的方向上，第一OLED子像素11包括：下电极、位于第一电极上且沿第一OLED子像素11的列方向延伸的第一OLED发光结构以及位于第一OLED发光结构上的上电极。第一OLED子像素11的下电极靠近OLED阵列基板1设置。各个第一OLED子像素11的驱动方式为主动式，各个第一OLED子像素11的驱动对应显示驱动集成芯片12的部分数据信号通道。在一实施例中，下电极的形状可以为块状。
透明显示区10b包括一行、若干列的第二OLED子像素13。具体的，在图1中，透明显示区10b包括一行、若干列第二OLED子像素13。在垂直于OLED阵列基板1的方向上，每列第二OLED子像素13包括：沿第二OLED子像素13的列方向延伸的第一电极、位于第一电极上、沿列方向延伸的第二OLED发光结构以及位于第二OLED发光结构上的第二电极132。在一实施例中，第一电极的形状可以为条状。
各列第二OLED子像素13被驱动时，透明显示区10b执行显示功能；各列第二OLED子像素13未被驱动时，透明显示区10b执行透光功能。各列第二OLED子像素13的驱动方式为被动式，各列第二OLED子像素13的驱动对应同一显示驱动集成芯片12的剩余数据信号通道。各列第一OLED子像素11与各列第二OLED子像素12的驱动对应的所有数据信号通道的数据对应显示区10的一帧画面。
参照图2所示，在垂直于OLED阵列基板1所在平面的方向上，第二OLED子像素13包括：沿列方向延伸的第一电极131、第二OLED发光结构133以及第二电极132。各第二OLED发光结构133由像素定义层14隔开。第一OLED子像素11的结构与第二OLED子像素13的结构相同。其它可选实施例中，第二OLED发光结构133之间也可以无像素定义层14。
第二OLED子像素13与第一OLED子像素11的区别在于：每列第一OLED子像素11中，下电极、第一OLED发光结构与上电极在非透明显示区10a中呈若干行列的阵列排布且相互隔开。而在每列第二OLED子像素13中，第一电极131与第二OLED发光结构133自透明显示区10b的顶端沿列方向延伸至底端，每列第二OLED子像素13中的第二电极132可以自透明显示区10b的顶端沿列方向延伸至底端，也可以如图2所示，各列第二OLED子像素13的第二电极132连成一面电极。在一实施中，各个第一OLED子像素的上电极与各个第二OLED子像素的第二电极连接成一面电极。
图1中，透明显示区10b位于非透明显示区10a顶端的中部，其它可选实施例中，透明显示区10b也可以位于非透明显示区10a中的任意部位。例如，透明显示区10b也可以位于非透明显示区10a顶端的左部或右部，或者非透明显示区10a底端的左部、右部、或中部，或者非透明显示区10a中部。
图1与图2中，透明显示区10b的所有第二OLED子像素13为同色子像素。可选实施例中，透明显示区10b的所有第二OLED子像素13可以为红色子像素、绿色子像素、蓝色子像素、黄色子像素中的一个。换言之，透明显示区10b执行显示功能时，该区域为单色发光。
其它可选实施例中，第二OLED子像素13中的第一电极131以及第二OLED发光结构133的排布方式也可以设置为与第一OLED子像素11完全相同。将透明显示区10b的第二OLED子像素13中的第一电极131、第二OLED发光结构133设置为沿列方向延伸的若干列。具体的，在一实施例中，第一电极131、第二OLED发光结构133自透明显示区10b的顶端延伸至底端。相对于阵列式分布的若干行列单元，这样的排布方式可以减少图形膜层的交界，改善透光时的衍射问题。
一个可选实施例中，每列第二OLED子像素13的第一电极在OLED阵列基板所在平面上的投影可以由一个图形单元或者两个以上的图形单元组成。该图形单元的形状为圆形、椭圆形、哑铃形、葫芦形或矩形中的一种。将图形单元设置为上述形状能进一步减少衍射。
一个可选实施例中，沿列方向延伸的第一电极131在所述列方向上的长度与行方向的宽度的比值大于20:1。具体实施过程中，上述比值还可以为大于40:1，100:1，200:1或800:1。
以下介绍透明显示区10b的各列第二OLED子像素13的发光驱动方式。
被动驱动式OLED(Passive Matrix OLED，PMOLED)，也称无源驱动式OLED，单纯地将第二电极、第一电极构造成矩阵状，以扫描方式点亮阵列中位于行列交叉点的像素，每个像素都是在短脉冲模式下被操作，进行瞬间高亮度发光。换言之，每个第二OLED子像素13的寻址直接受控于外部电路。该外部电路可以受控于显示驱动集成芯片(Display Driver Integrated Circuit，DDIC)。
图3是透明显示区各列第二OLED子像素的一种被动驱动式电路的示意图。参照图3所示，各列第二OLED子像素13的第一电极共同连接至一开漏电路的输出端。该开漏电路的输入端连接至显示驱动集成芯片12的一个数据信号通道。各列第二OLED子像素13的第二电极接地。
开漏电路包括一NMOS(N-Metal-Oxide-Semiconductor)管T1、一PMOS(P-Metal-Oxide-Semiconductor)管T2、一存储电容C以及一上拉电阻R，工作过程如下。
第一时间段，当数据信号通道的数据信号为低电平“0”时，NMOS管T1截止，高电平V GH通过上拉电阻R施加在PMOS管T2的栅极，PMOS管T2截止，各列第二OLED子像素13未被驱动。
第二时间段，当数据信号通道的数据信号为高电平“1”时，NMOS管T1导通，NMOS管T1的漏极接地。PMOS管T2导通，控制源极电源电压VCC流向透明显示区10b每一列第二OLED子像素13的第一电极。下一时间段，数据信号通道的数据信号变为低电平“0”，此时NMOS管T1截止，由于上拉电阻R阻值较大，对电容C的充电需要时间，所以PMOS管T2的栅极电压上升缓慢，PMOS管T2短暂导通一小段时间，第二OLED子像素13短暂发光直至PMOS管T2完全关断。
上述开漏电路工作过程中，可以调节第一时间段与第二时间段的比值、存储电容C以及一上拉电阻R的大小，利用视觉延迟，使各列第二OLED子像素13连续发光。
该数据信号通道携带的颜色数据与各列第二OLED子像素13的颜色一致。换言之，由于透明显示区10b仅具有一行第二OLED子像素13，且在该实施例中，各列第二OLED 子像素13均为同色子像素，因而仅需向各列第二OLED子像素13施加同一驱动电流，该驱动电流占据显示驱动集成芯片(DDIC)的一个数据信号通道(数据线、source线)。显示驱动集成芯片的其余数据通道可以提供给非透明显示区10a的各列第一OLED子像素11，每列第一OLED子像素11占据一个数据信号通道。显示驱动集成芯片的所有数据信号通道的数据对应显示区10的一帧画面。换言之，在一个图像刷新周期内，各数据通道的数据是由对一副图像处理得来。
其它可选实施例中，开漏电路也可以采用其它电路结构，本申请对此并不加以限制。
图4是透明显示区各列第二OLED子像素的另一种被动驱动式电路的示意图。参照图4所示，每一列第二OLED子像素13的第一电极连接至一个开漏电路的输出端。每一开漏电路的输入端连接至显示驱动集成芯片12的一个数据信号通道。各第二OLED子像素13的第二电极接地。
每一开漏电路的结构以及连接方法与图3中的开漏电路的结构以及连接方法相同。每个数据信号通道携带的颜色数据与所连接的第二OLED子像素13的颜色一致。换言之，由于透明显示区10b仅具有一行第二OLED子像素13，因而仅需向各列第二OLED子像素13施加驱动电流，各列第二OLED子像素13的驱动电流占据显示驱动集成芯片(DDIC)的若干个数据信号通道(source线)，每列第二OLED子像素13占据一个数据信号通道。显示驱动集成芯片的其余数据通道可以提供给非透明显示区10a的各列第一OLED子像素11，每列第一OLED子像素11占据一个数据信号通道。显示驱动集成芯片的所有数据信号通道的数据对应显示区10的一帧画面。
图3与图4实施例中，各列第二OLED子像素13的第一电极的走线设置在OLED阵列基板1上的边框区，该边框区位于显示区10的外围区域。其它可选实施例中，各列第二OLED子像素13的第一电极的走线也可以设置在非透明显示区10a或透明显示区10b。相对于将走线设置在透明显示区10b的实施例，将走线设置在边框区以及非透明显示区10a的实施例能进一步减少透明显示区10b的图形膜层，进一步改善透光模式下的衍射问题。
相对于图4所示的实施例，图3所示的实施例中：数据信号通道的数目较少，连接数据信号通道和子像素的走线数目也较少、占用面积较少。
图5是透明显示区各列第二OLED子像素13的又一种被动驱动式电路的示意图。参照图5所示，各列第二OLED子像素13的第一电极共同连接至一运算放大电路的输 出端，运算放大电路的正向输入端连接显示驱动集成芯片的一个数据信号通道。运算放大电路的反向输入端连接第一电阻R1，反向输入端与输出端之间连接有第二电阻R2。该电路对应的放大倍数为：(R2+R1)/R1。本实施例中，各列第二OLED子像素13的第一电极上施加的驱动电流可以通过数据信号的大小进行调节。本实施例中，各列第二OLED子像素13共占据了显示驱动集成芯片(DDIC)的一个数据信号通道(source线)。显示驱动集成芯片的其余数据通道可以提供给非透明显示区10a的各列第一OLED子像素11，每列第一OLED子像素11占据一个数据信号通道。显示驱动集成芯片的所有数据信号通道的数据对应显示区10的一帧画面。
其它可选实施例中，也可以参照图4所示的实施例，每一列第二OLED子像素13的第一电极连接至一运算放大电路的输出端，每个运算放大电路的正向输入端连接至显示驱动集成芯片的一个数据信号通道。每列第二OLED子像素13的显示与否以及亮度大小可以单独控制。在这一实施例中，各列第二OLED子像素占据显示驱动集成芯片(DDIC)的若干个数据信号通道(source线)，每列第二OLED子像素13占据一个数据信号通道。显示驱动集成芯片的其余数据通道可以提供给非透明显示区10a的各列第一OLED子像素11。显示驱动集成芯片的所有数据信号通道的数据对应显示区10的一帧画面。
其它可选实施例中，运算放大电路也可以采用其它电路结构，本申请对此并不加以限制。
图6是本申请另一实施例中的OLED阵列基板的俯视图。图6所示的OLED阵列基板2与图1所示的OLED阵列基板1大致相同，区别仅在于：所述透明显示区10b内的各列第二OLED子像素13或所述透明显示区10b内的某一区域内的各列第二OLED子像素13为多个颜色的子像素。相邻的若干个不同颜色的各列子像素形成一像素单元。换言之，在一像素单元中，一列红色子像素、一列绿色子像素、一列蓝色子像素交替分布。其它可选实施例中，像素单元中的各列子像素也可以为除红、绿、蓝外的其它颜色。
各列第二OLED子像素13的具体结构请参照前述实施例中的具体结构，以下重点介绍多个颜色的第二OLED子像素带来的驱动方式与所有列像素都为同色第二OLED子像素的驱动方式的不同之处。
图7是透明显示区各列第二OLED子像素的一种被动驱动式电路的示意图。参照图7所示，相邻的三个不同颜色的第二OLED子像素形成一第二OLED像素单元。各第二OLED像素单元中的各列同色第二OLED子像素13的第一电极连接至一开漏电路的输 出端。开漏电路的输入端连接至显示驱动集成芯片12的一个数据信号通道。开漏电路结构及工作过程参照图3实施例中的开漏电路结构及工作过程。换言之，所有红色子像素的第一电极通过开漏电路连接至同一R数据信号通道；所有绿色子像素的第一电极通过开漏电路连接至同一G数据信号通道；所有蓝色子像素的第一电极通过开漏电路连接至同一B数据信号通道。由于透明显示区10b仅具有一行、三列第二OLED像素单元，因而需向各列同色第二OLED子像素13施加同一驱动电流。该驱动电流来源于显示驱动集成芯片(DDIC)的三个数据信号通道(source线)。显示驱动集成芯片的其余数据通道可以提供给非透明显示区10a的各列第一OLED子像素11，每列第一OLED子像素11占据一个数据信号通道。显示驱动集成芯片的所有数据信号通道的数据对应显示区10的一帧画面。
其它可选实施例中，各第二OLED像素单元中的每列同色第二OLED子像素13的第一电极也可以连接至一开漏电路的输出端。每一开漏电路的输入端连接显示驱动集成芯片12的一个数据信号通道。换言之，各列红色子像素的第一电极通过各自的开漏电路连接至一个R数据信号通道；各列绿色子像素的第一电极通过各自的开漏电路连接至一个G数据信号通道；各列蓝色子像素的第一电极通过各自的开漏电路连接至一个B数据信号通道；各列第二OLED子像素共占据显示驱动集成芯片(DDIC)的若干个数据信号通道(source线)，每列第二OLED子像素13占据显示驱动集成芯片的一个数据信号通道。
图8是透明显示区各列第二OLED子像素的另一种被动驱动式电路的示意图。参照图8所示，相邻的三个不同颜色的第二OLED子像素形成一第二OLED像素单元。各第二OLED像素单元中的各列同色第二OLED子像素13的第一电极连接至同一运算放大电路的输出端。该运算放大电路的输入端连接显示驱动集成芯片的一个数据信号通道。其它可选实施例中，各第二OLED像素单元中的各列同色第二OLED子像素13的第一电极连接至一个运算放大电路的输出端，每个运算放大电路的输入端连接显示驱动集成芯片的一个数据信号通道。实施例在这一情况下，数据信号通道的数目较少，走线数目也较少、占用面积较少。
图9是本申请再一实施例中的OLED阵列基板的俯视图。参照图9所示，本实施例中的OLED阵列基板3与前述实施例中的OLED阵列基板1、2大致相同，区别仅在于：某一列第二OLED子像素13'可以在透明显示区10b的中部一区段内沿列方向延伸、或自透明显示区10b的顶端沿列方向延伸至透明显示区10b的中部、或自透明显示区10b 的中部沿列方向延伸至透明显示区10b的底端。相邻若干列第二OLED子像素形成一图形，所述图形包括：电池形状的图形和/或表示信号强度的图形。不同于前述实施例中仅通过采用在第一电极上施加不同大小的驱动电流，和/或对不同颜色的子像素施加驱动电流以实现不同图案，在本实施例中，各列第二OLED子像素13'各种结构还可以互相结合以形成各种图案。
上述设置方式的各列第二OLED子像素13'可以为同色13"子像素13'，即透明显示区执行10b单色显示功能。各列第二OLED子像素13'也可以为不同颜色的第二OLED子像素13'，即透明显示区执行10b彩色显示功能。
图10是本申请又一实施例中的OLED阵列基板的俯视图。参照图10所示，本实施例中的OLED阵列基板4与前述实施例中的OLED阵列基板1、2、3大致相同，区别仅在于：某一列、某几列或所有列的第二OLED子像素13"在列方向上呈葫芦状。换言之，某一列、某几列或所有列的第二OLED子像素13"的第一电极、第二OLED发光结构在列方向上呈葫芦状。相对于第二OLED子像素呈直角矩形或圆角矩形，上述结构能进一步降低透光时的衍射现象。
上述形状的各列第二OLED子像素13"可以为同色子像素，即透明显示区10b执行单色显示功能。各列第二OLED子像素13"也可以为不同颜色的第二OELD子像素13"，即透明显示区10b执行彩色显示功能。
上述OLED阵列基板除了作为显示器件用外，还可以在其中设置触控层以用作触控面板。上述OLED阵列基板也可以作为半成品与其它部件集成、装配在一起形成如手机、平板电脑、车载显示屏等的显示装置。
显示装置中，OLED阵列基板的透明显示区10b下方可以设置光传感器。光传感器包括：摄像头、虹膜识别传感器以及指纹识别传感器中的一种或多种。
虽然本申请披露如上，但本申请并非限定于此。任何本领域技术人员，在不脱离本申请的精神和范围内，均可作各种更动与修改，因此本申请的保护范围应当以权利要求所限定的范围为准。
