技术领域
本公开涉及显示技术领域，具体地涉及一种显示面板及其驱动方法以及显示装置。
背景技术
全面屏手机已经引起了消费者越来越多的关注。由于全面屏手机无边框或边框很小，其有效显示区域覆盖了整个前面板。这导致原来设置在边框处的传感器如今需要占用有效显示区域的屏下空间，这些传感器亦可称为屏后传感器。然而，现有的有源矩阵有机发光二极管(AMOLED)显示面板的透过率不高，其无法满足屏后传感器的要求，这给AMOLED全面屏手机的实现带来了限制。

通过以下参照附图对本公开实施例的描述，本公开的上述以及其他目的、特征和优点将更为清楚，在附图中：
图1A示出了示例AMOLED显示面板的沿厚度方向的截面图。
图1B示出了示例AMOLED显示面板中的阵列基板的结构示意图。
图2示出了示例PMOLED显示面板的结构示意图。
图3示出了根据本公开实施例的显示面板的示意图。
图4示出了根据本公开另一实施例的显示面板的示意图。
图5示出了根据本公开实施例的显示装置的示意图。
图6示出了根据本公开实施例的对显示面板进行驱动的方法的流程图。
具体实施方式
以下参照附图，对本公开的示例实施例进行详细描述。贯穿附图，相同的元素由相同或相近的附图标记来表示。在以下描述中，一些具体实施例仅用于描述目的，而不应该理解为对本公开有任何限制，而只是本公开实施例的示例。在可能导致对本公开的理解造成混淆时，将省略常规结构或构造。应注意，图中各部件的形状和尺寸不反映真实大小和比例，而仅示意本公开实施例的内容。
在整个说明书中，对“一个实施例”、“实施例”、“一个示例”或“示例”的提及意味着：结合该实施例或示例描述的特定特征、结构或特性被包含在本公开至少一个实施例中。因此，在整个说明书的各个地方出现的短语“在一个实施例中”、“在实施例中”、“一个示例”或“示例”不一定都指同一实施例或示例。此外，可以以任何适当的组合和/或子组合将特定的特征、结构或特性组合在一个或多个实施例或示例中。
还应注意的是，本领域技术人员可以理解，本文中的术语“A与B电连接”和“A电连接到B”可以是A与B直接电连接，也可以是A经由一个或多个其他组件与B电连接。
此外，还需要指出的是，在下文中“目标图像”指要在整个有效显示区域内显示的完整图像。
以下参考附图对本公开进行具体描述。
图1A示出了示例AMOLED显示面板的沿厚度方向(或显示面板的法线方向)的截面图。图1B示出了示例AMOLED显示面板中的阵列基板的结构示意图。
从图1A可见，AMOLED显示面板包括阴极层110、有机层120和阵列基板130。此外，根据图1B可知，阵列基板130包括以矩阵形式布置的多个像素(每个虚线框示意性地表示一个像素)，每个像素中都包括阳极电极140。AMOLED显示面板通过在各个像素中的阳极电极140与阴极层110之间形成稳定的驱动电流来使得各个像素中的有机层120稳定发光，从而使得显示面板呈现期望的图像。
具体地，AMOLED显示面板通过栅极驱动电路(例如GOA驱动电路)向各条 栅线(例如GATE1和GATE2)提供栅极驱动信号，通过源极驱动电路向各条数据线(例如DATA1-DATA3)提供源极驱动信号，实现对AMOLED显示面板的显示驱动。
在图1B中将每个像素的像素电路示例为具有2T1C(2个晶体管，1个存储电容器)结构，在AMOLED显示面板中，由于存储电容器的存在，使得每个像素在扫描驱动发光后可以在一帧中持续地发光，从而并不需要很高的瞬时亮度，功耗较低，寿命较长，能够用于实现较大尺寸的显示面板。
图2示出了示例PMOLED显示面板的结构示意图。
从图2可见，PMOLED显示面板包括阴极电极210、有机层220和与阳极电极230。其中，多个平行的条状阴极电极210(即横向的行电极)与多个平行的条状阳极电极230(即纵向的列电极)在有机层220的上下两侧分别相互垂直地布置，各阴极电极210与各阳极电极230在衬底的法线方向上的交叠区域形成像素矩阵(如图2中各个虚线框所示)。
具体地，在PMOLED显示面板中，通过行驱动电路和列驱动电路对阴极电极210和阳极电极230分别施加相应的驱动信号，在阴极电极210与阳极电极230的交叠区域处的像素上形成瞬时电流，使像素发出较强的瞬时亮度，通过对各个阴极电极210和阳极电极230顺序地进行扫描，利用瞬时发光在人眼中产生的残像实现对人眼的完整图像显示。
与AMOLED显示面板相比，PMOLED显示面板需要更高的瞬时亮度，功耗较高。然而，PMOLED中不需要设置阵列基板，其结构更为简单。
在制作较大尺寸的显示面板时，往往采用AMOLED面板来实现。然而，AMOLED与PMOLED相比，由于阵列基板的存在，透过率较低，对屏后传感器在其中的实现产生了不利的影响。
图3示出了根据本公开实施例的显示面板的示意图。
如图3所示，所述显示面板包括第一显示区域310和第二显示区域320。应该指出的是，在图3中为了便于说明将整个有效显示区域示为只包括第一显示区域310 和第二显示区域320，然而在其他实施例中，有效显示区域还可以包括其他区域。
在一些实施例中，第一显示区域是AMOLED区域，并且第二显示区域是PMOLED区域。应该理解的是，在其他实施例中，还可以将第一显示区域和第二显示区域实现为以其他方式进行显示或驱动的区域，例如，第一显示区域是PMOLED区域，第二显示区域是AMOLED区域，本公开对此不做限制。为了便于说明，本实施例以第一显示区域是AMOLED区域并且第二显示区域是PMOLED区域作为示例进行描述。
图3中还示出了第一驱动电路，其包括用于向第一显示区域310中的栅线提供栅极驱动信号的第一栅极驱动电路331和用于向第一显示区域310中的数据线提供源极驱动信号的第一源极驱动电路332。
第一栅极驱动电路331被配置为驱动第一显示区域310显示第一目标图像(目标图像的第一部分)。在一些实施例中，第一栅极驱动电路331可以是栅极阵列驱动(GOA)电路，其可以与像素一起制作于阵列基板上。
在图3所示的实施例中，采用单侧栅极驱动的方式，第一栅极驱动电路331只设置于显示面板的有效显示区域的第一侧边处(例如，如图3所示的右侧边)，第一源极驱动电路332设置于显示面板的有效显示区域的第二侧边处(例如，如图3所示的下侧边)。在这一情况下，如图3所示，第二显示区域320能够位于显示面板的有效显示区域的彼此相邻的第三侧边和第四侧边形成的角落处，其中，第三侧边与第一侧边相对，第四侧边与第二侧边相对。
如此设置第二显示区域320的位置的原因在于确保第一显示区域310中各个像素都能够接收到栅极驱动信号和源极驱动信号，并且不必对面板上的布线进行特殊的安排和设置。否则，如果第二显示区域320与第三侧边或第四侧边之间存在间隙的话，则第一显示区域410的位于该间隙处的部分中的像素由于第二显示区域320的阻断无法通过栅线接收到栅极驱动信号或通过数据线接收到源极驱动信号，无法实现正常显示。
图3中还示出了第二驱动电路340，第二驱动电路340与所述第一驱动电路彼 此独立地进行操作，被配置为驱动第二显示区域320显示第二目标图像(目标图像的第二部分)。应该理解的是，本文中“独立地进行操作”意味着一个驱动电路在进行操作时可以不受另一驱动电路的控制或影响，并不表示两个驱动电路的输入和输出之间不具有任何时序、频率或幅度上的关联。
在一些实施例中，所述第一目标图像与所述第二目标图像拼接成所述目标图像。
图4示出了根据本公开另一实施例的显示面板的示意图。
如图4所示，显示面板包括第一显示区域410和第二显示区域420。应该指出的是，在图4中为了便于说明将整个有效显示区域示为只包括第一显示区域410和第二显示区域420，然而在其他实施例中，有效显示区域还可以包括其他区域。
在一些实施例中，第一显示区域是AMOLED区域，并且第二显示区域是PMOLED区域。应该理解的是，在其他实施例中，还可以将第一显示区域和第二显示区域实现为以其他方式进行显示或驱动的区域，例如，第一显示区域是PMOLED区域，第二显示区域是AMOLED区域，本公开对此不做限制。为了便于说明，本实施例以第一显示区域是AMOLED区域并且第二显示区域是PMOLED区域作为示例进行描述。
图4中还示出了第一驱动电路，其包括用于向第一显示区域410中的栅线提供栅极驱动信号的第一栅极驱动电路431和用于向第一显示区域410中的数据线提供源极驱动信号的第一源极驱动电路432。
第一栅极驱动电路431被配置为驱动第一显示区域410显示第一目标图像。在一些实施例中，第一栅极驱动电路431可以是GOA电路，其可以与像素一起制作于阵列基板上。
在图4所示的实施例中，采用双侧栅极驱动的方式，第一栅极驱动电路431设置于显示面板的有效显示区域的第一侧边处(例如，如图4所示的右侧边)和与第一侧边相对的第三侧边处(例如，如图4所示的左侧边)，第一源极驱动电路432设置于显示面板的有效显示区域的第二侧边处(例如，如图4所示的下侧边)。在这一情况下，如图4所示，第二显示区域420能够位于显示面板的有效显示区域的第四侧边的边缘处，其中，第四侧边与第二侧边相对。
如此设置第二显示区域420的位置的原因在于确保第一显示区域410中各个像素都能够接收到栅极驱动信号和源极驱动信号，并且不必对面板上的布线进行特殊的安排和设置。否则，如果第二显示区域420与第四侧边之间存在间隙的话，则第一显示区域410的位于该间隙处的部分中的像素由于第二显示区域420的阻断无法通过数据线接收到源极驱动信号，无法实现正常显示。
图4的实施例通过采用双侧栅极驱动，使得第二显示区域的位置不再限于图3的实施例中的角落位置，从而使得制成的显示面板中能够更加灵活地设置屏后传感器的位置。
图4中还示出了第二驱动电路440，第二驱动电路440与第一驱动电路彼此独立地进行操作，被配置为驱动第二显示区域420显示第二目标图像。
在一些实施例中，所述第一目标图像与所述第二目标图像拼接成所述目标图像。
在一些实施例中，第一栅极驱动电路431的位于第一侧边处的第一部分与显示面板的各行像素所对应的栅线连接，并且第一栅极驱动电路431的位于第三侧边处的第二部分同样与显示面板的各行像素所对应的栅线连接。第一栅极驱动电路431的这两部分分别向各自所连接到的栅线提供栅极驱动信号。在本公开中，布置了第二显示区域420的位置处的栅线是断开的。可以认为断开的栅线仍然是一条栅线，这条栅线包括分离的两部分，一部分位于第二显示区域420与第一侧边之间，另一部分位于第二显示区域420与第三侧边之间。备选地，还可以认为断开的栅线形成两条栅线，两条栅线连接到同一行像素，并且分别用于对该行像素的一部分进行驱动。应该理解的是，不管如何认定断开的栅线，都不会影响本公开实施例的实施。在上述实施例中，断开的栅线的两个分离部分(或断开的栅线形成的两条栅线)分别被第一栅极驱动电路的第一部分和第二部分驱动，不会影响第一显示区域的显示效果。
在另一些实施例中，第一栅极驱动电路431的位于第一侧边处的第一部分与显示面板的奇数行像素所对应的栅线连接，并且第一栅极驱动电路431的位于第三侧边处的第二部分与显示面板的偶数行像素所对应的栅线连接。第一栅极驱动电路431的这两部分分别向各自所连接到的栅线提供栅极驱动信号。在这一实施例中，断开 的栅线的两个分离部分(或断开的栅线形成的两条分离栅线)中只有一个分离部分(或一条分离栅线)被第一栅极驱动电路的第一部分或第二部分驱动。在第二显示区域420的面积较小的情况下，可以通过适当地牺牲与第二显示区域420相对应的像素行区域的分辨率(这部分区域可以用于显示对分辨率不敏感的特定内容)来实现更为简化的驱动电路结构。
图5示出了根据本公开实施例的显示装置500的示意图。
如图5所示，显示装置500包括显示面板510、处理器520和屏后传感器530。
显示面板510可以是根据本公开各实施例所示的显示面板(例如，如图3或图4所示的显示面板)，其中包括第一显示区域511和第二显示区域512。在一些实施例中，所示第一显示区域511为AMOLED区域，第二显示区域512为PMOLED区域。
同样，显示面板510还包括第一驱动电路513和第二驱动电路514，第一驱动电路513被配置为驱动第一显示区域511显示第一目标图像，第二驱动电路514被配置为驱动第二显示区域512显示第二目标图像。应该理解的是，图5中第一驱动电路513和第二驱动电路514的位置以及电连接关系只是示意性地示出，并不用于对具体的电连接关系以及位置关系进行限定。
处理器520可以是任意形式的处理单元或模块，例如计算机的中央处理单元、手机的处理芯片等。处理器520与第一驱动电路513和第二驱动电路514电连接，并且被配置为向第一驱动电路513和第二驱动电路514提供信号，以使得第一驱动电路513和第二驱动电路514驱动第一显示区域511和第二显示区域512同步地显示各自目标图像，并且两个区域显示的内容能够呈现预定的显示效果。具体地，处理器520可以向第一驱动电路513和第二驱动电路514提供第一目标图像和第二目标图像的数据信息和用于使第一显示区域511和第二显示区域512同步地显示所述第一目标图像和第二目标图像(第一目标图像和第二目标图像构成一目标图像)的控制信号。在一些实施例中，对于第一驱动电路513(示例为AMOLED驱动电路)，数据信息可以指示要对各个像素的像素电路的数据线施加的信号的电平，控制信号可以包括但不限于栅极驱动电路的输入信号。再例如，对于第二驱动电路514(示 例为PMOLED驱动电路)，数据信息可以指示要在阴极电极上施加的电压，控制信号可以用于控制对阳极电极和阴极电极进行扫描的时序。
屏后传感器530可以是任何适于安装在显示面板下方并感测穿过显示面板的信号的传感器，例如红外传感器、光学传感器、接近传感器等。
在图5所示的实施例中，屏后传感器530设置在显示面板510的显示表面与衬底之间与第二显示区域512对应的位置处，以能够感测在第二显示区域512处从显示表面穿过的信号。
应该理解的是，虽然在图5的实施例中示出了处理器520和屏后传感器530，但在本公开的其他实施例中够可以省略处理器520和屏后传感器530中的至少一个，或增加其他的元件，本公开对此不加以限制。
图6示出了根据本公开实施例的对显示面板进行驱动的方法600的流程图。所述方法600可以用于对根据本公开任意实施例(例如，图3或图4的实施例)的显示面板进行驱动，因此上文中结合图3和图4进行的解释和说明在此同样适用。
所述方法600包括步骤S610至步骤S630。
在步骤S610中，向第一驱动电路提供第一图像信号，第一图像信号至少用于显示第一目标图像。
在一些实施例中，第一图像信号只用于显示第一目标图像。
在另一些实施例中，第一图像信号用于显示整个目标图像。
在步骤S620中，向第二驱动电路提供第二图像信号，第二图像信号至少用于显示第二目标图像。
在一些实施例中，第二图像信号只用于显示第二目标图像。
在另一些实施例中，第二图像信号用于显示整个目标图像。
在步骤S630中，向第一驱动电路和第二驱动电路提供时序信号，使得第一驱动电路和第二驱动电路分别驱动第一显示区域和第二显示区域同步地显示第一目标图像和第二目标图像。
在一些实施例中，所述方法600可以由用于对第一驱动电路和第二驱动电路进行控制的处理器实现，例如，如图5所示的显示装置中的处理器520。
以上的详细描述通过使用示意图、流程图和/或示例，已经阐述了众多实施例。在这种示意图、流程图和/或示例包含一个或多个功能和/或操作的情况下，本领域技术人员应理解，这种示意图、流程图或示例中的每一功能和/或操作可以通过各种结构、硬件、软件、固件或实质上它们的任意组合来单独和/或共同实现。
虽然已参照几个典型实施例描述了本公开，但应当理解，所用的术语是说明和示例性、而非限制性的术语。由于本公开能够以多种形式具体实施而不脱离公开的精神或实质，所以应当理解，上述实施例不限于任何前述的细节，而应在随附权利要求所限定的精神和范围内广泛地解释，因此落入权利要求或其等效范围内的全部变化和改型都应为随附权利要求所涵盖。
