Description

显示面板、显示装置及显示驱动方法 技术领域
本公开涉及显示技术领域，尤其是指一种显示面板、显示装置及显示驱动方法。
背景技术
现代消费性电子装置多配备液晶显示面板(Liquid Crystal Display，LCD)或者有机电激光(OrganicLight-Emitting Diode，OLED)显示面板作为人机接口，每个显示面板包括一个像素元阵列，通常像素元阵列基于从原始图像产生的电子数据，图像被划分成相等区域的像素，像素的数目等于显示面板上的像素元的数目。随着显示屏幕尤其是手机显示屏幕的应用需求的逐渐增高，设置屏下摄像模组成为当前显示面板的发展趋势。

目前，为了使显示面板上对应屏下摄像模组的显示区域满足上述两种状态的显示效果，通常在该显示区域上进行像素删减，但采用该设置结构，显示区域的像素单元密度小于正常显示区域的像素单元密度，会使得该显示区域的显示分辨率小于正常显示区域的显示分辨率，从而严重影响显示效果。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
为解决采用屏下摄像头的显示面板，为了满足透光要求，摄像头对应显示区域相较于正常显示区域进行像素删减，会使得摄像头对应显示区域的显示分辨率小于正常显示区域的显示分辨率，严重影响显示效果的问题，本公开实施例提供一种显示面板和显示驱动方法，通过设计显示区域的像素结构，并制定相应的像素渲染技术(Sub Pixel Rendering，SPR)，在保证摄像头对应显示区域达到最大透过率的同时，使该区域的显示效果更接近正常显示区域的显示效果。
如图1所示，本公开实施例所述显示面板包括相邻的第一显示区域11和第二显示区域12。
其中，第二显示区域12形成为透光显示区，在显示面板安装于电子设备上时，在电子设备的内部，对应第二显示区域12的位置，可以安装感光元件 如为摄像头，用于透过第二显示区域12采集图像，形成为屏下摄像头显示结构。
可选地，第一显示区域11围绕第二显示区域12设置，第一显示区域11与第二显示区域12相组合形成为显示面板的整个显示区域。其中一实施方式，显示面板的整个显示区域可以均为透光显示区，或者仅第二显示区域12为显示面板的透光显示区域，用于实现屏下摄像头的图像采集。可选地，显示面板为OLED显示面板。
如图2和图3所示，本公开实施例所述显示面板，第一显示区域11具有第一像素密度，第二显示区域12具有第二像素密度，第一像素密度大于第二像素密度；
其中，第一显示区域11和第二显示区域12分别包括多个像素重复单元110，每一像素重复单元110分别包括沿第一方向a依次排列的第一颜色的第一子像素111、第二颜色的第二子像素112、第三颜色的第三子像素113和第一颜色的第四子像素114；其中，第一颜色的第一子像素111的发光面积和第一颜色的第四子像素114的发光面积均小于第二颜色的第二子像素112与第三颜色的第三子像素113的发光面积；
在第二显示区域12，相邻的三个像素行中，第一像素行的第一个像素重复单元1与第三像素行的第二个像素重复单元2之间，在第二像素行上形成虚拟像素空间3；该虚拟像素空间3的面积至少大于或等于一个像素重复单元110所占据面积；其中，所述像素行的长度延伸方向平行第一方向a。
本公开实施例所述显示面板，可选地，第一显示区域11的多个像素重复单元110的子像素依次连接排列，第二显示区域12的多个像素重复单元110之间具有间隔空间，形成为第一显示区域11的第一像素密度大于第二显示区域12的第二像素密度的结构。需要说明的是，在图2中，第二显示区域12上，阴影填充部分为实际子像素，形成多个像素重复单元110；多个像素重复单元110之间的空白部分所标示的RGB子像素，并非为实际的子像素，其中用子像素区域标示，仅用于说明多个像素重复单元110之间的位置关系。
本公开实施例所述显示面板，在依据上述实施结构设置像素重复单元110的基础上，在第二显示区域12的相邻三个像素行中，位于相间隔像素行上的 第一个像素重复单元1和第二个像素重复单元2，该两个像素重复单元110之间的像素行上形成虚拟像素空间，也即不存在真实排布的像素重复单元。在进行图像显示驱动时，通过该虚拟像素空间，可以利用SPR驱动算法，在该虚拟像素空间形成为虚拟像素单元，保证摄像头对应显示区域达到最大透过率的同时，达到提升该显示区域分辨率的效果，使该第二显示区域的显示效果更接近正常显示区域(第一显示区域)的显示效果。
本公开实施例中，可选地，如图2和图4所示，在第一显示区域11，相邻三个像素重复单元110中，第二像素重复单元1102的第一颜色的第一子像素111与第一个像素重复单元1101的第一颜色的第四子像素114沿第二方向b排列，第二个像素重复单元1102的第一颜色的第四子像素114与第三个像素重复单元1103的第一颜色的第一子像素111沿第二方向b排列；所述第二方向b垂直于所述第一方向a，第一像素重复单元1101、第二像素重复单元1102和第三像素重复单元1103沿第一方向a依次排列。
基于该实施结构，每一像素重复单元110中，第一子像素111和第四子像素114在第二方向b上的宽度，分别为第二子像素112和第三子像素113在第二方向b上的宽度的二分之一。另外，可选地，每一像素重复单元110中，第一子像素111、第二子像素112、第三子像素113和第四子像素114在第一方向a上的宽度均相等。
基于该实施方式，在第一显示区域11，相邻两个像素重复单元110中，相邻两个像素重复单元110的两个第一颜色的子像素相组合后沿第二方向b排列后，在第二方向上的总宽度等于第二颜色的子像素和第三颜色的子像素在第二方向上的宽度，相邻两个像素重复单元110的两个第一颜色的子像素相组合后的总面积等于一个第二颜色的子像素的面积，同时也等于一个第三颜色的子像素的面积。
本公开实施例中，可选地，所述第一颜色为绿色，所述第二颜色为红色，所述第三颜色为蓝色。需要说明的是，本公开实施例所述显示面板，第一显示区域11和第二显示区域12依据上述方式排布时，第一颜色、第二颜色和第三颜色不限于仅能够为分别所列举的上述颜色。
采用该实施例所述显示面板，在第一显示区域11，形成为多个R、G和 B依次排列的结构，但G子像素包括沿第二方向(也即像素列)方向排列的两个像素部分，相较于现有技术，该G子像素的两个像素部分分别属于不同的像素重复单元，两个像素部分可以分别连接不同驱动线路，分别进行驱动发光。第二显示区域12的每一像素重复单元110中，第二颜色的第二子像素112和第三颜色的第三子像素113的一侧分别设置有一个第一颜色的子像素，也即第一子像素111和第四子像素114。这样，第二显示区域12的每一像素重复单元110包括一个第二颜色的子像素、一个第三颜色的子像素和两个第一颜色的子像素。
本公开实施例所述显示面板，可选地，如图2和图3所示，在第二显示区域12，同一像素行中，相邻两个像素重复单元110为间隔设置；也即，相邻两个像素重复单元110之间形成有间隔空间，不设置像素重复单元。
另外，相间隔两个像素行上的多个像素重复单元110交错排列。具体地，如图2和图3所示，相邻的三个像素行中，第一像素行的第一个像素重复单元1，在相间隔的第三像素行上的正投影，至少部分位于第三像素行的第二个像素重复单元2和第三个像素重复单元4之间。可选地，该正投影包括位于第二个像素重复单元2和第三个像素重复单元4之间的部分，以及还包括分别与第二个像素重复单元2和第三个像素重复单元4相重叠的部分。
参阅图2和图3所示，在第二显示区域12，相邻两个像素重复单元110之间形成的间隔空间，为像素重复单元110的子像素沿第一方向a的宽度L的整数倍。其中，L为非零的自然数。
具体地，沿第一方向a，第一子像素111、第二子像素112、第三子像素113和第四子像素114的宽度均为L；其中，在第二显示区域12，每一像素行上，相邻两个像素重复单元110之间的间隔在第一方向a上的宽度为L的整数倍。
可选地，本公开实施例中，在第二显示区域12，每一像素行上，相邻两个像素重复单元110之间的间隔在第一方向a上的宽度至少为L的2倍。
可选地，在本公开实施例中，在第二像素行上，相邻两个像素重复单元110之间的间隔在第一方向a上的宽度为3L的整数倍。
采用该实施结构，使得第一像素行的第一个像素重复单元1与第三像素 行的第二个像素重复单元2之间，在第二像素行上形成虚拟像素空间3，且保证虚拟像素空间3的面积至少大于或等于一个像素重复单元110所占据面积。

其中，第二显示区域12还包括与第一显示区域11相连接的第二边缘122，第二边缘122与第一边缘121相对，且第一边缘121至第二边缘122的方向为平行于第二方向b。
也即，具体地，在第二显示区域12，对于每一像素重复单元110，第一子像素111和第四子像素114设置于靠近第一边缘121的像素部分上。
另外，可选地，本公开实施例中，如图2所示，在第一显示区域11和第二显示区域12上，相邻两个像素行的子像素交错排列。

可选地，在第一颜色为绿色，第二颜色为红色，第三颜色为蓝色时，位于R子像素和B子像素两侧的G子像素属于上一行线路的控制子像素，本行的R子像素和B子像素属于本行线路的控制子像素。

可选地，在进行显示驱动时，上一行寻址的相邻两个G在左右分布亚像素的两边，本行寻址的R、B在像素中间。本行的G子像素不点亮。也即，两个G子像素在驱动行上属于上一行控制，本行的R子像素和B子像素在像素中间，本行控制的G子像素不点亮。
在第一显示区域11和第二显示区域12，每一像素重复单元110形成为图4所示结构，且每相邻的三个像素行中，第一像素行的第一个像素重复单元1与第三像素行的第二个像素重复单元2形成为一组相邻像素，且在一组相邻像素内的第一个像素重复单元1与第二个像素重复单元2之间不设置像素结 构，形成为虚拟像素空间，用于通过SPR驱动算法形成为虚拟像素单元。

采用本公开实施例所述显示面板，通过在第二显示区域形成为非均匀的第一颜色的子像素的排布结构，经第二颜色的子像素和第三颜色的子像素进行亮度调制，能够实现虚拟像素亮度中心的均匀分布。
另外，本公开实施例所述显示面板，利用相邻两个像素重复单元共用相邻的第二颜色的子像素和第三颜色的子像素(如为R子像素或B子像素)，从而在通常物理像素的基础上，增加了虚拟显示像素，这样使得2个物理像素在视觉感官上变为3个像素单元，因此分辨率相较于通常显示面板增加了1.5倍，达到第二显示区域也即对应摄像头区域的分辨率增加，使得相较于第一显示区域的显示效果之间的差别降低。
举例说明，为了增加第二显示区域的开口率，物理像素的分布密度相较于第一显示区域可以降低为第一显示区域的像素分布密度的四分之一，若常规OLED显示面板的像素单元的设置密度为720p，在第二显示区域的像素单元的设置密度为180p，采用本公开实施例所述显示面板，并利用上述的SPR驱动算法，可以使得在第二显示区域上实际观看到的分辨率达到270p，因此能够保证显示效果，同时达到满足屏下摄像模组所对应显示区域的透光要求。
