显示面板及终端设备 技术领域
本公开涉及显示技术领域，具体而言，涉及一种显示面板及终端设备。
背景技术
对于手机、平板电脑等具有摄像头的终端设备的屏幕而言，屏幕对应于摄像头的区域通常需要开孔，从而无法发光，这不利于提高屏占比。目前，虽然存在屏下摄像技术，使得摄像头所在区域也可显示图像，避免开孔，并可正常拍摄，但屏下摄像区域的显示效果和拍摄后的成像质量均有待提高。
需要说明的是，在上述背景技术部分公开的信息仅用于加强对本公开的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。

如图2和图3所示，本公开实施方式的显示面板PNL至少可划分为可发光的显示区AA和显示区AA外的不发光的外围区WA。同时，显示面板PNL可包括衬底SU和像素单元，其中：
衬底SU可为聚酰亚胺等柔性透明材质，也可以是玻璃等硬质透明材质，且衬底SU可以是多层或单层结构。
各像素单元可阵列分布在衬底SU一侧，且每个像素单元可独立发光，以显示图像。每个像素单元可包括像素电路和发光元件LD，发光元件LD设于像素电路远离衬底SU的一侧，且与像素电路连接，可通过像素电路控制发光元件LD发光。LD可以是OLED(有机发光二极管)、QLED(量子点发光二极管)、Micro LED或Mini LED等，其可以包括第一电极ANO、第二电极CAT和位于第一电极ANO和第二电极CAT间的发光层EL。
如图2和图3所示，各像素电路PC可位于一电路层CL，电路层CL可与衬底SU形成驱动背板BP。电路层CL还可包括位于外围区WA内的外围电路。外围电路一方面可通过像素电路与发光元件LD连接，通过控制像素电路可控制通过发光元件LD的电流，从而控制发光元件LD的亮度。
下面对像素电路和发光器件进行详细说明：
像素电路可包括多个晶体管，还可以包括电容，其可以是3T1C、7T1C等像素电路，nTmC表示一个像素电路包括n个晶体管(用字母“T”表示)和m个电容(用字母“C”表示)。以7T1C的像素电路为例，其可包括7个晶体管和1个电容，即第一复位晶体管T1、补偿晶体管T2、 驱动晶体管T3、写入晶体管T4、第一发光控制晶体管T5、第二发光控制晶体管T6、第二复位晶体管T7以及存储电容Cst。
如图4所示，第一复位晶体管T1的第一极与第一复位信号线VIL1连接，用于接收复位信号Vinit1，第二极与驱动晶体管T3的栅极和存储电容Cst的第一极板连接。补偿晶体管T2的第一极与驱动晶体管T3的第二极连接，第二极与驱动晶体管T3的栅极连接。写入晶体管T4的第一极与数据线DL连接，用于接收数据信号Data，第二极与驱动晶体管T3的第一极连接。第一发光控制晶体管T5的第一极和存储电容Cst的第二极板与电源线VDL连接，用于接收第一电源信号VDD，第二极与驱动晶体管T3的第一极连接。第二发光控制晶体管T6的第一极与驱动晶体管T3的第二极连接，第二极与发光元件的第一电极连接。第二复位晶体管T7的第一极与第二复位信号线VIL2连接，用于接收第二复位信号Vinit2，第二极与第二发光控制晶体管T6的第二极连接。发光元件的第二电极可接收第二电源信号VSS。
同时，为了控制各晶体管的导通和关断，第一复位晶体管T1的栅极与第一复位控制线REL1连接，用于输入第一复位控制信号RE1，第二复位晶体管T7的栅极与第二复位控制线REL2连接，用于输入第二复位控制信号RE2。补偿晶体管T2和写入晶体管T4的栅极与扫描线GL连接，用于输入扫描信号GA，第一发光控制晶体管T5和第二发光控制晶体管T6的栅极与发光控制线EML连接，用于输入发光控制信号EM。该像素电路可以用于响应于所连接的各信号端提供的信号，驱动所连接的发光元件发光。
前述的第一复位信号线VIL1、第二复位信号线VIL2、数据线DL、电源线VDL以及第一复位控制线REL1、第二复位控制线REL2、扫描线GL和发光控制线EML均可称作信号线SL，且信号线SL可以沿第二方向X或第一方向Y延伸，例如，数据线DL和电源线VDL沿第一方向Y延伸，其它信号线SL可沿第二方向X延伸。
此外，按照晶体管的特性区分可以将晶体管分为N型和P型晶体管。本公开实施例以晶体管均采用P型晶体管为例进行说明。基于本公开对该实现方式的描述和教导，本领域普通技术人员在无需做出创造性劳动前 提下，能够容易想到将本公开实施例的像素电路结构中至少部分晶体管采用N型晶体管，即采用N型晶体管或N型晶体管和P型晶体管组合的实现方式，因此，这些实现方式也是在本公开实施例的保护范围内的。
下面以像素电路的各晶体管均为P型低温多晶硅晶体管为例，对其工作原理进行说明：
在复位阶段：第一复位控制信号RE1为低电平信号，第一复位晶体管T1导通，驱动晶体管T3的栅极和存储电容Cst的第一极板被写入复位信号Vinit1，对N1节点实现初始化，消除上一帧图像的数据的影响。
在写入阶段：通过扫描信号GA为低电平信号，可使写入晶体管T4和补偿晶体管T2导通，向驱动晶体管T3的栅极和存储电容Cst的第一极板Cst1写入数据信号DA，即经过N3节点和N2节点向N1节点写入数据信号DA，直至电位达到Vdata+vth。其中，Vdata为数据信号Da的电压，Vth为驱动晶体管T3的阈值电压。写入晶体管T4和补偿晶体管T2的扫描信号GA可为同一信号。同时，第二复位控制信号RE2为低电平信号，使第二复位晶体管T7导通，发光元件LD的第一电极和第二发光控制晶体管T6的第二极被写入第二复位信号Vinit2，对N4节点进行复位，实现初始化，进一步消除上一帧图像的数据的影响。
在发光阶段：发光控制信号EM为低电平信号，第一发光控制晶体管T5和第二发光控制晶体管T6导通，驱动晶体管T3在存储电容Cst存储的电压Vdata+Vth和第一电源信号VDD的作用下导通，此时，发光元件LD发光。
在一些实施方式中，如图2以及图14-图18所示，像素电路的晶体管和电容均位于电路层CL，以像素电路的晶体管的为顶栅型低温多晶硅晶体管为例，电路层CL可包括沿远离衬底SU的方向依次堆叠的半导体层SEL、第一栅绝缘层GI1、第一栅极层GAT1、第二栅绝缘层GI2、第二栅极层GAT2、介电层ILD、第一源漏层SD1、钝化层PVX和第一平坦层PLN1。其中，
如图15所示，半导体层SEL可包括各晶体管(T1-T7)的沟道以及连接至少部分沟道的掺杂区，通过掺杂区可实现部分晶体管的连接。
如图16所示，第一栅极层GAT1可包括存储电容Cst的第一极板 Cst1和部分信号线SL(扫描线GL、第一复位控制线REL1、第二复位控制线REL2和发光控制线EML)，且这些信号线SL与半导体层SEL交叠的区域为各晶体管的栅极。举例而言，本行像素电路的第一复位晶体管T1的栅极T11、上一行像素电路的第二复位晶体管T7的栅极和本行像素电路的第一复位控制线REL1可以为一体结构。补偿晶体管T2的栅极T21、写入晶体管T4的栅极T41和扫描线GL可以为一体结构。驱动晶体管T3的栅极T31和存储电容Cst的第一极板Cst1可以为一体结构。第一发光控制晶体管T5的栅极T51、第二发光控制晶体管T6的栅极T61和发光控制线EML可以为一体结构。本行像素电路的第二复位晶体管T7的栅极T71、下一行像素电路的第一复位晶体管T1的栅极以及本行像素电路的第二复位控制线REL2可以为一体结构。
如图17所示，第二栅极层GAT2可包括存储电容Cst的第二极板Cst2和部分信号线SL(第一复位信号线VIL1和第二复位信号线VIL2)，第二栅极层GAT2还可包括屏蔽电极BK。存储电容Cst的第二极板Cst2具有一个镂空区域。驱动晶体管T3的栅极T31在衬底SU上的正投影可以覆盖该镂空区域在衬底SU上的正投影。镂空区域在衬底SU上的正投影可以为多边形。
如图18所示，介电层ILD开设有多个过孔，例如包括第一过孔V1至第十五过孔V15。其中，第一过孔V1至第八过孔V8内的介电层ILD、第二栅绝缘层GI2和第一栅极层GAT1被去掉，暴露出半导体层SEL的表面。第九过孔V9内的介电层ILD和第二栅绝缘层GI2被去掉，暴露出第一栅极层GAT1的表面。第十过孔V10至第十五过孔V15内的介电层ILD被去掉，暴露出第二栅极层GAT2的表面。
如图14所示，第一源漏层SD1可包括部分信号线SL(数据线DL和电源线VDL)，还可包括多个连接电极(例如，第一连接电极CP1至第六连接电极CP6)。数据线DL可以通过第三过孔V3与写入晶体管T4的连接。电源线VDL可以通过第十二过孔V12与屏蔽电极BK连接，还可以通过第十三过孔V13与存储电容Cst的第二极板Cst2连接。屏蔽电极BK用于屏蔽数据电压跳变对关键节点的影响，避免数据电压跳变影响像素电路的关键节点的电位，提高显示效果。第一连接电极CP1可 以通过第一过孔V1与第一复位晶体管T1连接，还可以通过第十过孔V10与第一复位信号线INL1a连接。第二连接电极CP2可以通过第二过孔V2与补偿晶体管T2连接，还可以通过第九过孔V9与驱动晶体管T3的栅极T31连接。第三连接电极CP3可以通过第五过孔V5与第二发光控制晶体管T6连接。第四连接电极CP4可以通过第六过孔V6与第二复位晶体管T7连接，还可以通过第十五过孔V15与第二复位信号线INL2连接。第五连接电极CP5可以通过第七过孔V7与上一行像素电路的第二复位晶体管T7连接，还可以通过第十一过孔V11与第二复位信号线INL2连接。第六连接电极CP6可以通过第八过孔V8与下一行像素电路的第一复位晶体管T1连接，还可以通过第十四过孔V14与第一复位信号线INL1连接。
此外，在本公开的一些实施方式中，显示面板PNL的电路层CL还可包括第二源漏层和第二平坦层，第二源漏层可设于第一平坦层PLN1远离衬底SU的表面，第二平坦层可覆盖第二源漏层。数据线DAL和电源线VDL可位于第二源漏层。发光元件LD可设于第二平坦层远离衬底SU的一侧。
上述的像素电路的仅为一种实施方式，本公开的像素电路还可采用其它结构，在此不做特殊限定。
如图2所示，发光元件LD可设于电路层CL远离衬底SU的一侧，且与像素电路连接。发光元件LD的数量可以有多个，且阵列分布。每个发光元件LD可连接一个像素电路PC，形成像素像素单元PU。该发光元件LD可以是OLED(有机发光二极管)、QLED(量子点发光二极管)、Micro LED或Mini LED等，其可以包括第一电极ANO、第二电极CAT和位于第一电极ANO和第二电极CAT间的发光层EL。
以OLED为例，第一电极ANO可设于电路层CL远离衬底SU的表面，发光层EL可包括沿远离驱动背板BP的方向层叠的空穴注入层、空穴传输层、发光材料层、电子传输层和电子注入层。各个发光元件LD可共用第二电极CAT，也就是说，第二电极CAT可以是连续的整层结构，且第二电极CAT可延伸至外围区，并可接收第二电源信号VSS，第一电 极ANO则阵列分布，确保各发光元件LD可以独立发光。此外，为了限定发光元件LD的发光范围，防止串扰，可在设置在第一电极ANO的表面设置像素定义层PDL，其可设有露出各第一电极ANO的开口，发光层EL在开口内与第一电极ANO层叠。
各发光元件LD可至少共用发光材料层，使得各发光元件LD的发光颜色相同，此时，为了实现彩色显示，可在发光元件LD远离衬底SU的一侧设置彩膜层，通过彩膜层中与各发光元件LD对应的滤光部，实现彩色显示。当然，各个发光元件LD的发光材料层也可以使独立的，使得发光元件LD可以直接发出单色光，且不同发光元件LD的发光颜色可以不同，从而实现彩色显示。
此外，如图2所示，显示面板PNL还可包括覆盖各发光元件LD的封装层TFE，封装层TFE可包括第一无机层TFE1和第二无机层TFE2以及位于第一无机层TFE1和第二无机层TFE2之间的有机层IJP。第一无机层TFE1可覆盖发光元件LD。进一步的，显示面板PNL还可以包括设置在封装层TFE远离衬底SU的一侧的触控层、透明盖板等其它膜层，在此不再详述。
如图1所示，为了实现屏下摄像，可在显示面板PNL中设置透光区PAT，透光区PAT可全部位于显示区AA内，也可部分位于显示区AA内。一部分像素单元PU全部位于显示区AA内，而对于另一部分像素单元PU中的任意一个而言，其至少一部分可设于透光区PAT内，且像素单元PU位于透光区内的部分可定义为功能部FP，该功能部FP可以是像素单元PU的像素电路PC，也可以是发光元件LD。当然，功能部FP也可以是像素单元PU的全部。为此，可将像素单元PU至少分为第一像素单元PU1和第二像素单元PU2，第一像素单元PU1位于显示区AA内，而每个第二像素单元PU2的至少一部分位于透光区，第二像素单元PU2位于透光区PAT内的部分即为功能部FP。
透光区PAT的大小可与感光元件CAU相匹配，且透光率高于显示区AA，使得透光区PAT既可以发光，以显示图像，也可以透光，以供感光元件拍摄图像。进一步的，透光区PAT可设置多个，例如，透光区 PAT至少可包括第一透光区PAT1和第二透光区PAT2，第一透光区PAT1和第二透光区PAT2均设有第二像素单元PU2的功能部FP。感光元件CAU可通过多个透光区PAT拍摄图像。如图1和图3所示，通过使透光区PAT内的像素单元PU的密度小于显示区AA内的像素单元PU的密度，可减少像素单元对光线的遮挡，提高透光区PAT的透光率，实现屏下摄像；或者，也可以通过对像素单元PU的尺寸进行压缩，减小其对光线的遮挡，从而提高透光区PAT透光率；或者，还可以同时减小像素单元PU的密度和尺寸，提高透光区的透光率。
为了提高屏下摄像的成像效果，可使第一透光区PAT1和第二透光区PAT2内的像素电路PC的排布方式互补，使得感光元件CAU可以采集到至少两幅互补的图像，通过对互补的图像进行合成，可以得到更加清晰的图像，从而可以在保证显示效果的前提下，提高屏下摄像的成像效果。当然，也可以第一透光区PAT1和第二透光区PAT2内的发光元件LD的排布方式互补。也就是说，第一透光区PAT1和第二透光区PAT2的功能部FP互补。
由于像素单元PU对光线有一定的遮挡作用，本文中的第一透光区PAT1和第二透光区PAT2的功能部FP互补是指：第一透光区PAT1和第二透光区PAT2的功能部FP的位置不同，使得两个第一透光区PAT1和第二透光区PAT2内未被遮挡的区域可以叠加成一个完整的不被遮挡的透光区，下面对第一透光区PAT1和第二透光区PAT2内的功能部FP的排布方式互补的具体方案进行详细说明：
为了便于描述功能部FP的分布方式，可对透光区PAT进行划分，在其中划分出多个子区域SPA，子区域SPA的范围的大小以功能部FP占据的范围的大小为限，功能部FP在第二方向X上的边界和在第一方向Y上的边界围成的区域的大小即为一个子区域SPA的大小，因而可用子区域SPA描述透光区PAT内的功能部FP的排布方式。透光区PAT内的每个子区域SPA均可以设置功能部FP，也可以不设置功能部FP，不设置功能部FP的区域为透射区，透射区的透光率高于设置功能部FP的子区域，从而可用于提高透光率。
各个透光区PAT的形状为其在衬底SU上的正投影的形状，该形状均为圆形等，当然，也可以是三角形、矩形、梯形或其它多边形，此外，还可以是椭圆形、腰圆形等其它形状。第一透光区PAT1和第二透光区PAT2可沿第二方向X分布，当然，也可以沿第一方向Y分布。同时，为了便于感光元件CAU采集图像，可使第一透光区PAT1和第二透光区PAT2的间距小于第一透光区PAT1和第二透光区PAT2任一个在第二方向X或第一方向Y上的宽度，例如，透光区PAT的形状为圆形，则第一透光区PAT1和第二透光区PAT2的间距小于二者的直径。从而可使透光区PAT相对集中的分布，以便感光元件同时进行拍摄。
此外，透光区PAT可以设置在显示区AA的任意位置，例如，显示区AA为矩形，第一透光区PAT1和第二透光区PAT2可设置在显示区AA的同一拐角位置，也可以分别设置在两个拐角位置，或者，还可以设置在AA区的中心等其它位置。进一步的，透光区PAT的边界可与显示区AA的边界部分重合，也可以与显示区AA的边界具有一定的距离。
各透光区PAT的形状和大小相同，且各透光区PAT的子区域SPA均以相同的方式排布，例如，各个透光区PAT均包括n行和m列子区域SPA，n和m为正整数。同时，每个子区域SPA在其所处的透光区PAT中具有唯一的位置，可视为每个子区域SPA在其所处的透光区PAT中具有唯一的坐标，而只要通过一个坐标可以在每个透光区PAT中找到唯一的子区域SPA。
在透光区PAT中，仅部分子区域SPA设有功能部FP，且一个子区域SPA内设置一个功能部FP。在第一透光区PAT1和第二透光区PAT2中，位置相同的两子区域SPA仅有一个设有功能部FP，使得第一透光区PAT1内的被功能部FP遮挡的区域在第二透光区PAT2中不被功能部FP遮挡，第二透光区PAT2内的被功能部FP遮挡的区域在第一透光区PAT1中不被功能部FP遮挡。基于此，由于第一透光区PAT1和第二透光区PAT2的功能部FP互补排布，使得感光元件可以对同一场景采集到不同的图像，通过对两个图像的合成可以得到该场景的图像，可视为利用第一透光区PAT1和第二透光区PAT2的设置功能部FP的子区域SPA共同成像。
如图5所示，在本公开的第一实施方式中，可将第一透光区PAT1 和第二透光区PAT2均划分为多个沿第二方向X延伸的子区域组BPA，且各子区域组BPA可沿第一方向Y分布；每个子区域组BPA均包括沿第二方向X分布的多个子区域SPA，即子区域组BPA可沿第二方向X延伸。
进一步的，为了提高透光区的分辨率，可增加透光区PAT的功能部FP的数量，为此，可对透光区PAT内的功能部FP的尺寸进行压缩，举例而言：
为了描述描述，可进行如下定义：
子区域SPA的边界在第一方向Y上的最大距离为其长度；子区域SPA的边界在第二方向X上的最大距离为其宽度。
子区域组BPA的边界在第一方向Y上的最大距离为其宽度；子区域组BPA的边界在第二方向X上的最大距离为其长度。
第一像素单元PU的边界在第一方向Y上的最大距离为其长度；第一像素单元PU的边界在第二方向X上的最大距离为其宽度。
功能部FP的边界在第一方向Y上的最大距离为其长度；功能部FP的边界在第二方向X上的最大距离为其宽度。
在本公开的一些实施方式中，在第一方向Y上，可使透光区PAT内的至少部分子区域SPA的长度小于显示区AA内的至少部分第一像素单元PU1的长度，使得透光区PAT内的功能部FP的长度小于显示区AA内的第一像素单元PU1的长度，从而在第一方向Y上对功能部FP进行压缩，以便使透光区PAT在第一方向Y可以设置更多的功能部FP。例如，第一透光区PAT1和第二透光区PAT2内的至少部分子区域SPA的长度不大于显示区AA内的至少部分第一像素单元PU1的长度的50％。
在本公开的另一些实施方式中，在第二方向X上，可使透光区PAT内的子区域SPA的宽度不大于显示区AA内的至少部分第一像素单元PU1的宽度，使得功能部FP在第二方向X上的长度小于显示区AA内的第一像素单元PU1的宽度，从而对第一透光区PAT1和第二透光区PAT2的功能部FP在第二方向X上进行压缩，以便使第一透光区PAT1和第二透光区PAT2在第二方向X上设置更多的功能部FP。例如，第一透光区PAT1和第二透光区PAT2内的子区域SPA的宽度不大于显示区 AA内的至少部分第一像素单元PU1的宽度的50％。
在本公开的其它实施方式中，可以同时沿第二方向X和第一方向Y压缩第一透光区PAT1和第二透光区PAT2的功能部FP，以便增加第一透光区PAT1和第二透光区PAT2的功能部FP的数量，从而增大第一透光区PAT1和第二透光区PAT2的分辨率。
下面以多个实施方式分别描述透光区PAT的子区域SPA的分布方式：
同一透光区PAT内的不同子区域组BPA的宽度可以相同，但长度可以不同，例如，第一透光区PAT1和第二透光区PAT2的形状为圆形，则至少一个子区域组BPA沿透光区PAT的径向延伸，且通过透光区PAT的圆点，其它子区域组BPA沿第一方向Y对称分布于该通过圆点的子区域组BPA的两侧。
第一透光区PAT1和第二透光区PAT2中的第i个子区域组BPA中的第j个子区域SPA仅一个设置功能部FP，而不同时设置功能部FP，i≤n，j≤m，m和n均为正整数。
进一步的，第一透光区PAT1中仅第2k-1个子区域组BPA的至少部分子区域SPA设有功能部FP。第二透光区PAT2中仅第2k个子区域组BPA的至少部分子区域SPA设有功能部FP，k为正整数。也就是说，第一透光区PAT1中的功能部FP位于奇数个子区域组BPA，而第二透光区PAT2的功能部FP位于偶数个子区域组BPA，从而实现前文提到的互补。
当然，也可以采用其它的方式在各子区域组BPA内设置功能部FP，只要能实现互补即可，例如，在第一方向Y上，第一透光区PAT1内的功能部FP位于其上半部分，而第二透光区PAT2内的功能部FP位于其下半部分。
如图6所示，在本公开的第二实施方式中，基于上述的第一实施方式，在第一方向Y上，可使一子区域组BPA的宽度与显示区AA内的子区域SPA的长度相同，且子区域SPA的长度不大于至少部分第一像素单元PU1的长度的50％，例如，45％、50％等，使得同一子区域组BPA内的子区域SPA沿第一方向Y排列成至少两行。
为了便于描述，可将同一子区域组BPA内的子区域SPA中的至少两行子区域SPA中的每一行定义为一亚子区域组BPA，且同一子区域组BPA内至少包括第一亚子区域组BPA1和第二亚子区域组BPA2。
一子区域组BPA内的各功能部FP设于第一亚子区域组BPA1和第二亚子区域组BPA2的子区域SPA内，且第一亚子区域组BPA1和第二亚子区域组BPA2的子区域SPA均设有功能部FP。设于同一行子区域SPA的功能部FP可以沿第二方向X依次相邻设置，即相邻两功能部FP设置在相邻的两子区域SPA。同时，在设有功能部FP的一个子区域组BPA中，具有多行子区域SPA，且至少一部分在第一方向Y上相邻的两子区域SPA设有功能部FP，例如，第一亚子区域组BPA1和第二亚子区域组BPA2的功能部FP的数量相等，且在第一方向Y上一一对应设置。
如图7所示，在本公开的第三实施方式中，与第二实施方式的不同点在于：设于同一行子区域SPA的功能部FP可以间隔设置，但第一透光区PAT1和第二透光区PAT2中位置相同的一行子区域SPA中功能部FP的分布方式仍应互补。例如，在同一子区域组BPA中，在第二方向X上，第一亚子区域组BPA1的功能部FP，与第二亚子区域组BPA2的功能部FP交替分布。进一步的，对于第一透光区PAT1和第二透光区PAT2中位置相同的两行子区域SPA，在第二方向X上，第一透光区PAT1的一行子区域SPA的奇数个子区域SPA设有功能部FP，第二透光区PAT2的一行子区域SPA的偶数个子区域SPA设有功能部FP。也就是说，在第一透光区PAT1的设有功能部FP的一行子区域SPA中，功能部FP设于第2k-1个子区域SPA；在第二透光区PAT2的设有功能部FP的一行子区域SPA中，功能部FP设于第2k个子区域SPA，k为正整数。
如图8所示，在本公开的第四实施方式中，第一透光区PAT1和第二透光区PAT2内的各子区域组BPA均设有功能部FP，且同一子区域组BPA内的各行子区域SPA均间隔设置有功能部FP，如此可以使可透光的子区域SPA和功能部FP均匀分散分布，有利于提高透光区的亮度的均一性。
进一步的，在设有功能部FP的一个子区域组BPA中，在第一方向Y上相邻的两子区域SPA中至多一个设有功能部FP，也就是说，功能部FP在第二方向X和第一方向Y上均间隔分布，在第二方向X上相邻的两功能部FP之间至少具有一个无功能部FP的子区域SPA，例如，在第一透光区PAT1的设有功能部FP的一行子区域SPA中，功能部FP设于第2k-1个子区域SPA；在第二透光区PAT2的设有功能部FP的一行子区域SPA中，功能部FP设于第2k个子区域SPA，k为正整数。而在第一方向Y上相邻的两功能部FP之间，至少具有一个无功能部FP的子区域SPA。
进一步的，在第一方向Y上，可使一子区域组BPA的宽度与至少部分第一像素单元PU1的长度相同，且子区域SPA的长度不大于至少部分第一像素单元PU1的长度的50％，例如，45％、50％等，使得同一子区域组BPA内的子区域SPA沿第一方向Y排列成至少两行。
如图9所示，在本公开的第五实施方式中，任意透光区PAT内的各子区域组BPA均设有功能部FP，且同一子区域组BPA内的各行子区域SPA均间隔设置有功能部FP。在第一方向Y上，可使一子区域组BPA的宽度与至少部分第一像素单元PU1的长度相同，且子区域SPA的长度不大于至少部分第一像素单元PU1的长度的50％，例如，45％、50％等，使得同一子区域组BPA内的子区域SPA沿第一方向Y排列成至少两行。
在设有功能部FP的一个子区域组BPA中，至少一部分在第一方向Y上相邻的两子区域SPA设有功能部FP。也就是说，功能部FP在第二方向X上间隔分布，但在第一方向Y上，同一子区域组BPA内的两功能部FP可以相邻设置，即二者之间无其它子区域SPA。
如图10所示，在本公开的第六实施方式中，第一透光区PAT1中仅第2k-1个子区域组BPA的至少部分子区域SPA设有功能部FP；第二透光区PAT2中仅第2k个子区域组BPA的至少部分子区域SPA设有功能部FP；k为正整数。本实施方式的功能部FP的排布方式与第二实施方式类似，不同点在于，本实施方式中的同一子区域组BPA内的子区域 SPA沿第一方向Y排列成至少两行，且相邻两行子区域SPA在第一方向Y上错位排布，即相邻两行子区域SPA在第二方向X上部分交叠，也就是说，同一子区域组BPA内的全部子区域SPA均沿第二方向X分布，且两行子区域SPA沿第二方向X交替分布，位于同一行的相邻两子区域SPA之间存在位于另一行的一子区域SPA的部分区域，从而实现第二方向X上的错位。
进一步的，在第二方向X上，可使一子区域组BPA的宽度与至少部分第一像素单元PU1的长度相同，且子区域SPA的长度大于至少部分第一像素单元PU1的长度的50％，但小于至少部分第一像素单元PU1的长度，例如，75％、80％等，以便以上述错位的方式设置两行子区域SPA。
进一步的，可使子区域SPA的形状为平行四边形，且具有两个沿第二方向X延伸的侧边和两个与第一方向Y呈指定夹角的侧边，指定夹角为锐角。相应的，设于本实施方式的子区域SPA的功能部FP的边界可以是平行四边形，相较于矩形的子区域SPA，本实施方式的子区域SPA可视为倾斜设置，有利于提高空间利用率。
如图11所示，在本公开的第七实施方式中，可将透光区PAT划分为多个沿第一方向Y延伸的子区域组BPA，且各子区域组BPA沿第二方向X分布；每个子区域组BPA均包括沿第一方向Y分布的多个子区域SPA。本实施方式的子区域组BPA可参考上文的第二实施方式中的子区域组BPA，主要区别在于子区域组BPA的延伸方向不同。
为了在本实施方式中实现功能部FP的互补排布，可使第一透光区PAT1中仅第2k-1个子区域组BPA的至少部分子区域SPA设有功能部FP，并使第二透光区PAT2中仅第2k个子区域组BPA的至少部分子区域SPA设有功能部FP，k为正整数，即第一透光区PAT1中仅奇数个子区域组BPA设有功能部FP，而第二透光区PAT2中仅偶数个子区域组BPA设有功能部FP。
进一步的，第一透光区PAT1和第二透光区PAT2内的子区域SPA的宽度不大于至少部分第一像素单元PU1的宽度的50％。同一子区域组BPA内的子区域SPA沿第二方向X排列成至少两列，一列子区域SPA 中的各子区域SPA可沿第一方向Y分布，以便在不减小透光率的前提下，增加功能部FP的数量，以便增大透光区的分辨率。同一子区域组BPA的相邻两列功能部FP可沿第二方向X一一对应设置；或者，功能部FP在第二方向X和第一方向Y上均间隔分布，在第二方向X上相邻的两像功能部FP之间至少具有一个无功能部FP的子区域SPA，在第一方向Y上相邻的两功能部FP之间至少具有一个无功能部FP的子区域SPA。
需要说明的是，上述的第一至第七实施方式主要是针对第一透光区PAT1和第二透光区PAT2的说明，在本公开的一些实施方式中，显示面板PNL可以有三个或者更多个透光区PAT，只要至少有两个互补的透光区PAT即可，其它透光区PAT可以与两个互补的透光区PAT采用相同的功能部FP排布方式，当然，也可以不同，在此不做特殊限定。
如图12所示，基于上文中提到的显示面板PNL，可使第二像素单元PU2的功能部FP即为第二像素单元PU2自身，第二像素单元PU2均位于第一透光区PAT1和第二透光区PAT2。连接显示区AA的第一像素单元PU1的像素电路PC的部分信号线SL可沿第二方向X穿过至少一个透光区PAT，且一信号线SL与显示区AA内的至少一行第一像素单元PU1的像素电路PC和透光区PAT内的至少一行第二像素单元PU2的像素电路PC连接，从而可通过同一信号线SL驱动透光区PAT内的一行第二像素单元PU2。例如，第一透光区PAT1和第二透光区PAT2可沿第二方向X分布，部分信号线SL可依次穿过第一透光区PAT1和第二透光区PAT2，且与第一透光区PAT1和第二透光区PAT2中的至少一行第二像素单元PU2的像素电路PC连接。
如图12所示，在本公开的一些实施方式中，若存在沿第二方向X延伸的子区域组BPA，且一子区域组BPA包括至少两行子区域SPA，且同一子区域组BPA的各行子区域SPA均设有功能部FP，例如上文中的第一至第四实施方式。可使部分信号线SL沿第一方向Y弯折，以便使透光区PAT的每一行像素电路PC均能连接一信号线SL。具体来说，可使至少一信号线SL具有沿第一方向Y弯折的弯折部，弯折部位于透光区内，且与透光区内的至少一行像素电路PC连接。弯折部可包括第二 方向X延伸的连接部和连接于连接部两端的延伸部，延伸部可沿第一方向Y延伸。
以上文中的7T1C像素电路PC为例，上述的信号线SL可以包括扫描线GL、第一复位控制线REL1、第二复位控制线REL2、第一复位信号线INL1和第二复位信号线INL2中的一个或多个，在一些实施方式中，连接透光区PAT的任意一行第二像素单元PU2的像素电路PC的沿第二方向X延伸的任意信号线SL均同时连接一行位于第一像素单元PU1的像素电路PC。
如图13所示，在本公开的一些实施方式中，第二像素单元PU2的发光元件LD位于透光区PAT，第二像素单元PU2的像素电路PC和第一像素单元PU1均位于显示区AA，也就是说，功能部FP为第二像素单元PU2的发光元件LD。第二像素单元PU2的像素电路PC和发光元件LD可通过导电线IL连接，导电线IL从显示区AA延伸至透光区PAT内，也就是说，第二像素单元PU2还可包括一连接像素电路PC和发光元件LD的导电线IL。同时，为了避免导电线IL对透光率造成较大影响，导电线IL的材料可为ITO(氧化铟锡)等透明导电材料。
此外，导电线IL可设于发光元件LD和像素电路PC之间，且不同的第二像素单元PU2的导电线IL可以位于不同层，也就是说，可以设置多层透明导电材料层，相邻两层用绝缘材料分隔。每一层均可设有导电线IL。当然，各导电线IL也可以位于同一层。
为了在显示区AA内容纳第二像素单元PU2的像素电路PC，可对一部分第一像素单元PU1的像素电路PC进行压缩，使一部分第一像素单元PU1的像素电路PC的宽度小于另一部分第一像素单元PU1的像素电路PC的宽度，从而为第二像素单元PU2的像素电路PC留出空间。
当然，也可以对所有第一像素单元PU1的像素电路PC均沿第二方向X进行压缩；只要能使显示区AA内容纳第二像素单元PU2的像素电路PC即可。此外，也可以将部分第二像素单元PU2的像素电路PC设置与显示面板PNL的外围区WA内。
需要说明的是，图13中仅示出了部分第二像素单元PU2及其导电 线IL，其它第二像素单元PU2的导电线IL的走线方式可参考图13的方式，但不以此为限，只要能将位于显示区AA的像素电路PC和位于透光区PAT的发光元件LD连接起来即可。
本公开实施方式还提供一种终端设备，该终端设备可以是手机、平板电脑、电视或其它具有屏下摄像功能的电子设备，在此不再一一列举。如图1所示，本公开的终端设备可包括显示面板PNL和感光元件CAU，其中：
显示面板PNL以是上述任意实施方式的显示面板PNL，其结构可参考上文中的驱动背板BP和显示面板PNL的实施方式，在此不再详述。
感光元件CAU可设于衬底SU远离像素单元PU的一侧，感光元件CAU在衬底SU的正投影与透光区PAT在衬底SU的正投影至少部分交叠。
在本公开的一些实施方式中，感光元件CAU的数量为多个，其可包括第一感光元件CAU1和第二感光元件CAU2，第一感光元件CAU1与第一透光区PAT1一一对应设置，举例而言，第一透光区PAT1在衬底SU的正投影与第一透光区PAT1在衬底SU的正投影至少部分交叠，从而可透过第一透光区PAT1采集图像。第二透光区PAT2在衬底SU的正投影与第二透光区PAT2在衬底SU的正投影至少部分交叠，从而可透过第二透光区PAT2采集图像。
外界的光线可透过透光区PAT照射到对应的第一感光元件CAU1和第二感光元件CAU2上，第一感光元件CAU1和第二感光元件CAU2可根据对应的透光区PAT透过的光线产生电信号，以便生成图像。第一感光元件CAU1和第二感光元件CAU2可包括图像传感器，例如CCD图像传感器或CMOS图像传感器等。
在此不做特殊限定。第一感光元件CAU1和第二感光元件CAU2可独立采集图像，也就是说，第一感光元件CAU1和第二感光元件CAU2产生的电信号均可以用于形成一副完整的图像。
此外，为了对感光元件CAU从多个透光区PAT拍摄的图像进行合成，最终得到更加清晰的图像，终端设备还可包括处理器，其可与感光 元件CAU的第一感光元件CAU1和第二感光元件CAU2连接，可对各第一感光元件CAU1和第二感光元件CAU2采集到的信息进行处理，合成一个图像。以终端设备为手机为例，该处理器可以是手机主板上的处理器，也可以是专门设置的独立的可以进行图像处理的处理器。
举例而言，第一透光区PAT1和第二透光区PAT2的功能部FP的排布方式互补，相应的，二者的可透光的子区域SPA互补，使得第一感光元件CAU1和第二感光元件CAU2被遮挡的区域互补，通过第一感光元件CAU1和第二感光元件CAU2各自的未被遮挡的区域获取的电信号，可合成出清晰的图像。第一感光元件CAU1和第二感光元件CAU2的遮挡和未遮挡区域的电信号可通过电信号的强度(例如电压或电流)来判断。图像合成的具体方式在此不做特殊限定。
感光元件CAU可以基于可见光来生成图像，还可基于红外线或其它光线来生成图像，例如，感光元件CAU可包括红外线传感器，通过接收外界的红外线形成红外线图像，以便于根据红外线图像识别指纹图案、虹膜图案、面部图案等。或者，感光元件CAU还可以包括照度传感器，其可以测量终端设备周围的照度，并且显示面板PNL可以基于所测量的照度来调节显示面板的亮度。此外，感光元件CAU还可以采用激光雷达(Light Detection and Ranging，LIDAR)传感器等。
感光元件CAU不仅可以用于拍摄图像的相机，还可用于通过输出并检测光来测量距离、用于输出光的小型灯。
