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，减小正常显示区域与摄像头对应显示区域之间的区域差异。
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所示，本公开实施例所述显示面板，第一显示区域11包括依次连接排列的多个像素重复单元100，第二显示区域12包括相互间隔的多个像素重复单元100。其中，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。通过减小第二显示区域12的像素分布密度，提高第二显示区域12的透光率，满足屏下摄像头的图像采集要求。
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100；多个像素重复单元100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100之间的位置关系。
其中，如图2所示，并结合图3，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100，每一像素重复单元100分别包括位于相邻像素行的两个像素组101，且相较于位于不同像素重复单元101的两个像素组101，位于同一像素重复单元101中的两个像素组101的距离最近；
每一像素组101中分别包括多个不同颜色的子像素，且位于同一像素重复单元100的两个像素组101中，不同颜色的子像素沿像素行的排列次序不同，第一像素组中的第一颜色的子像素和第三颜色的子像素分别与第二像素组中的第二颜色的子像素相邻，第二像素组中的第一颜色的子像素和第二颜色的子像素与第一像素组中的第三颜色的子像素与相邻。
采用该实施例所述显示面板，每一像素重复单元100分别包括位于相邻行的两个像素组101，在进行显示驱动时，能够以每一像素重复单元100内的子像素进行共用，确定相应的驱动像素单元，利用SPR驱动算法，形成虚拟像素单元，达到提高摄像头对应显示区域分辨率的效果，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。
另外，本公开实施例所述显示面板，利用两个像素组中，第一像素组中的第一颜色的子像素和第三颜色的子像素分别与第二像素组中的第二颜色的子像素相邻，第二像素组中的第一颜色的子像素和第二颜色的子像素与第一像素组中的第三颜色的子像素相邻，使得两个像素组中，第一像素组的其中一颜色的子像素，与第二像素组中不同颜色的子像素相邻，这样在利用SPR驱动算法形成虚拟像素单元时，每一像素重复单元100内不同像素组的子像素能够共用，达到提高摄像头对应显示区域分辨率的效果。
本公开实施例中，可选地，结合图2和图3所示，像素重复单元100所包括的两个像素组101，第一像素组1011中，蓝色B子像素、绿色G子像素和红色R子像素依次排列；第二像素组1012中，红色R子像素、蓝色B子像素和绿色G像素依次排列。其中，第一像素组1011中的蓝色B子像素和绿色G子像素与第二像素组1012中的红色R子像素相邻，第一像素组1011中的绿色G子像素和第一像素组1011中的红色R子像素与第二像素组1012中的蓝色B子像素相邻。同样，第二像素组1012中的红色R子像素与蓝色子像素分别和第一像素组1011中的绿色G子像素相邻；第二像素组1012中的蓝色B子像素与绿色G子像素分别与第一像素组1011中的红色R子像素相邻。
本公开实施例中，如图3所示，像素重复单元100所包括的两个像素组101，第二像素组1012相较于第一像素组1011沿行的延伸方向a(第一方向)偏移一个子像素宽度L的二分之一；也即，第二像素组1012相较于第一像素组1011沿行的延伸方向a偏移L/2的宽度。
需要说明的是，本公开实施例中，行的延伸方向a可以定义为显示面板显示图像时，从左至右的水平方向，也即指向显示面板的像素行的其中一边缘的方向；行的延伸方向的相反方向b为与行的延伸方向a相反的方向，也即为第二方向。列的延伸方向c可以定义为显示面板显示图像时，从上至下的竖直方向，同理，列的延伸方向的相反方向d为与列的延伸方向c相反的方向。
可选地，本公开实施例所述显示面板，两个像素组101中，每一子像素在像素行上的宽度相等，第二像素组1012中第一颜色的子像素相较于第一像素组1011中第一颜色的子像素，沿行的延伸方向a偏移1.5个子像素宽度L。
进一步地，第二像素组1012中第二颜色的子像素相较于第一像素组1011中第二颜色的子像素，沿行的延伸方向的相反方向b偏移1.5个子像素宽度。
具体地，如图3所示，以两个像素组101分别包括蓝色、红色和绿色的子像素，第一颜色为蓝色、第二颜色为红色，第三颜色为绿色为例，第二像素组1012中第一颜色(也即为蓝色)的子像素相较于第一像素组1011中第一颜色(也即为蓝色)的子像素，沿行的延伸方向a偏移1.5个子像素宽度L。
进一步地，两个像素组101中，第二像素组1012中第二颜色(也即为红色)的子像素相较于第一像素组1011中第二颜色(也即为红色)的子像素，沿行的延伸方向的相反方向b的相反方向偏移1.5个子像素宽度L。
在此基础上，第三像素组1012中第三颜色(也即为绿色)的子像素相较于第一像素组1011中第三颜色(也即为绿色)的子像素，沿行的延伸方向a偏移1.5个子像素宽度L。
本公开实施例中，如图2和图3所示，每一像素组101分别包括一个第一颜色的子像素、一个第二颜色的子像素和沿列的延伸方向排列(沿像素列排列)的两个第三颜色的子像素，其中两个第三颜色的子像素的总发光面积等于一个第一颜色的子像素的发光面积，且一个第一颜色的子像素的发光面积等于一个第二颜色的子像素的发光面积。
可选地，如图2和图3所示，两个像素组101的第一像素组1011中，沿行的延伸方向a，第一颜色的子像素、沿列的方向排列的两个第三颜色的子像素、第二颜色的子像素依次排列；两个像素组101的第二像素组1012中，沿行的延伸方向a，第二颜色的子像素、第一颜色的子像素、沿列的方向排列的两个第三颜色的子像素依次排列。
本公开实施例中，可选地，第一颜色为蓝色、第二颜色为红色，第三颜色为绿色。
也即，具体地，如图2和图3所示，在一个像素重复单元100，沿行的延伸方向a，相邻行的第一像素组1011中，蓝色的子像素、沿列的方向排列 的两个绿色的子像素、红色的子像素依次排列；第二像素组1012中，沿行的延伸方向a，红色的子像素、蓝色的子像素、沿列的方向排列的两个绿色的子像素依次排列。
需要说明的是，相邻行的第一像素组1011和第二像素组1012中，不同颜色的子像素的排列次序不限于上述所列举形式，只要两个像素组101中不同颜色的子像素的排列次序不同，且满足第二像素组1012中第一颜色的子像素相较于第一像素组1011中第一颜色的子像素，沿行的延伸方向偏移1.5个子像素宽度，第二像素组1012中第二颜色的子像素相较于第一像素组1011中第二颜色的子像素，沿行的延伸方向的相反方向偏移1.5个子像素宽度，能够使得两个像素组中，第一像素组的其中一颜色的子像素，与第二像素组中不同颜色的子像素相邻，即属于本公开所述显示面板中像素重复单元100的设置结构。
进一步，本公开实施例所述显示面板，第二显示区域12中，沿行的延伸方向a和沿列的延伸方向c，每一像素重复单元100分别与相邻的像素重复单元100间隔至少一个像素重复单元100的区域。
具体地，如图2所示，沿行的延伸方向a，相邻的第一像素重复单元110与第二像素重复单元120间隔一个像素重复单元100的区域，也即间隔一个像素重复单元沿行的延伸方向a上的一个宽度；沿列的延伸方向b，相邻的第一像素重复单元110与第三像素重复单元130间隔一个像素重复单元100的区域，也即间隔一个像素重复单元沿列的延伸方向b上的一个宽度，具体为两个像素行的宽度。
本公开实施例所述显示面板，采用上述实施结构，显示面板包括多个像素重复单元100，在第一显示区域11，沿行、列的延伸方向，多个像素重复单元100分别依次连接排列；在第二显示区域12，沿行、列的延伸方向，多个像素重复单元100分别相互间隔排列。而且，在第一显示区域11和第二显示区域12，每一像素重复单元100分别包括两个像素组101，两个像素组101分布在相邻的两个像素行。
可选地，在一个像素重复单元100中，第一颜色为蓝色、第二颜色为红色，第三颜色为绿色时，采用上述第一像素组1011和第二像素组1012中子 像素的排列形式，第一像素组1011中红色的子像素的中心与第二像素组1012中红色的子像素的中心，沿行的延伸方向上的距离位于28um至32um之间，可选地为30um；沿列的延伸方向上的距离位于30um至36um之间，可选地为34um；第一像素组1011中蓝色的子像素的中心与第二像素组1012中蓝色的子像素的中心，沿行的延伸方向上的距离位于28um至32um之间，可选地为30um；沿列的延伸方向上的距离位于40um至45um之间，可选地为42um。
可选地，在多个像素重复单元100，每一像素组101分别包括红色R、绿色G、绿色G和蓝色B四个子像素。其中，红色的子像素的发光面积等于蓝色的子像素的发光面积，两个绿色的子像素沿列的延伸方向排列，且两个绿色的子像素的总发光面积等于红色的子像素的发光面积和蓝色的子像素的发光面积。
利用上述的像素重复单元100中子像素的排布形式，通过SPR驱动算法，形成虚拟像素单元，其中每一虚拟像素单元中的G子像素对应表现为红绿蓝像素中的g信号，R、B子像素按同行左右相邻虚拟像素共享算法(也即子像素共用算法)表现相邻红绿蓝像素中的r信号和g信号。
可选地，在进行显示驱动时，在一个像素组101中，沿列的延伸方向上排列的两个G子像素，其中上侧的G子像素，配属于上一行寻址，下侧的G子像素，配属于本行像素寻址。
具体地，在进行显示驱动，接收到目标行上的行扫描信号时，响应于行扫描信号，以每一像素重复单元100中的第一像素组1011和第二像素组1012进行子像素借用，依次点亮沿目标行上的多个驱动像素单元，每一驱动像素单元包括其中一像素重复单元100中的第一像素组1011中的第一部分子像素和该像素重复单元100中的第二像素组1012中的第二部分子像素；
其中，该第一像素组1011或第二像素组1012位于该目标行。
可选地，每一驱动像素单元中的第一部分子像素和第二部分子像素分别包括不同颜色的子像素。
需要说明的是，第一像素组1011和第二像素组1012中，多个子像素可以分别连接不同行的驱动信号线，也即同一像素组中的多个子像素可以配属 于不同的像素寻址行。
具体地，如图2至图5所示，在目标行接收到行扫描信号时，依次向沿该目标行的延伸方向a排列的多个驱动像素单元200输入数据信号。其中，每两个相邻的驱动像素单元200所包括的子像素位于同一像素重复单元100。
可选地，在目标行为奇数行时，每两个相邻的驱动像素单元200中，第一驱动像素单元201包括像素重复单元100的第一像素组1011中的第一颜色的子像素、第三颜色的子像素，以及包括第二像素组1012中的第二颜色的子像素；第二驱动像素单元202包括像素重复单元100的第一像素组1011中的第三颜色的子像素、第二颜色的子像素，以及包括第二像素组1012中的第一颜色的子像素；

根据以上，并结合图4和图5，本公开实施例所述显示驱动方法中，两个所述像素组的第一像素组中，沿像素行方向，一个第一颜色的子像素、沿像素列方向排列的两个第三颜色的子像素、一个第二颜色的子像素依次排列；两个所述像素组的第二像素组中，沿像素行方向，一个第二颜色的子像素、一个第一颜色的子像素、沿像素列排列的两个第三颜色的子像素依次排列时，所述目标行i为奇数行，所述驱动像素单元中的子像素被点亮，形成的第i行的相邻两个虚拟像素单元中，对应第一个虚拟像素单元为第i行、第j列时，被点亮的子像素包括：
位于第i行、第j+1列的第二颜色(R颜色)的子像素；
位于第i行、第j列的第一颜色(B颜色)的子像素；
位于第j-1行、第j-1列的第三颜色(G颜色)的子像素；
位于第i行、第j列的第三颜色的子像素；
对应第二个虚拟像素单元为第i行、第j列时，被点亮的子像素包括：
位于第i行、第j+1列的第二颜色的子像素；
位于第i+1行、第j+1列的第一颜色的子像素；
位于第i-1行、第j-1列的第三颜色的子像素；
位于第i行、第j列的第三颜色的子像素。
采用上述的显示驱动方法，在向奇数行输入行扫描信号时，相邻进行数 据信号输入的第一驱动像素单元201和第二驱动像素单元202共用相邻的绿颜色的子像素；在向偶数行输入行扫描信号时，相邻进行数据信号输入的第一驱动像素单元201和第二驱动像素单元202共用相邻的蓝色的子像素，因此相较于通常的物理像素，增加了虚拟的中间像素，原有两个像素组，在视觉感官上变为四个像素组，从而使分辨率相较于通常显示面板增加了2倍，达到使第二显示区域也即对应摄像头区域的分辨率增加，相较于第一显示区域的显示效果之间的差别降低。
采用该实施结构，为了增加第二显示区域的开口率，可以使该第二显示区域的物理像素在原数量的基础上，减少到通常技术的像素设置数量的四分之一。
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。举例说明，若常规OLED显示面板的像素单元的设置密度为720p(利用SPR驱动算法进行计算之后虚拟现实分辨率为1080p)，也即所形成虚拟像素单元的设置密度为720p时，摄像头所对应显示区域的物理像素为720/4＝180p，选用SPR驱动算法使得分辨率增加了2倍，所以最终摄像头所对应显示区域所观测得到的虚拟分辨率可以为360p。
因此，采用本公开实施例所提供的显示面板，在保证摄像头对应显示区域达到最大透过率的同时，能够使该区域的显示效果更接近正常显示区域的显示效果，以减小正常显示区域与摄像头对应显示区域之间的区域差异。
