在一些示例性实施例中，如图9所示，上述像素单元3的第一像素开口10、第二像素开口11和第三像素开口12都设置在金属掩膜板上，各个发光区对应像素开口设置，第一像素开口10、第二像素开口11和第三像素开口12围绕着非开口区5，使得所有像素单元3的发光区排列组合如图9所示。图9中的每一个第一像素开口10和对应的第一发光区6，与第一像素开口10相邻的任两个第二像素开口11和对应的第二发光区7，以及与两个第二像素开口11都相邻的一个第三像素开口12和对应的第三发光区8，构成了一个像素单元3，像素单元3可以是第一像素单元19，可以是第二像素单元21，也可以是第三像素单元22。其中，多个第三发光区8形成阵列排布，同一行的多个第三发光区8在行方向上等间隔布置，相邻行的第三发光区8交错布置，例如第一行(即A1行)、第三行(即A3行)上的第三发光区8都在行方向上等间隔布置，第一行(即A1行)和第三行(即A3行)上的第三发光区8交错布置。同一列的多个第三发光区8在列方向上等间隔布置，相邻列的第三发光区8交错布置，例如第一列(即B1列)、第三列(即B3列)上的第三发光区8都在列方向上等间隔布置，第一列(即B1列)和第三列(B3列)上的第三发光区8交错布置。多个第二发光区7形成矩阵排布，同一行的多个第二发光区7在行方向上等间隔布置，相邻行的第二发光区7对应布置，例如第二行(即A2行)上的第二发光区7都在行方向上等间隔布置，第二行(即A2行)和第二列(即B2列)上的第二发光区7在列方向上对应第二列(即B2列)上相邻的第二发光区7。同一行相邻的两个第三发光区8之间具有一个第一发光区6，同一列相邻的两个第三发光区8之间也具有一个第一发光区6。同一行的第一发光区6的中心相对第三发光区8的几何中心在列方向上存在偏移情况，例如第一行(即A1行)，两个第一发光区6的中心相对第三发光区8的几何中心在列方向上存在偏移，而且偏移方向相反。同一列的第一发光区6的中心相对第三发光区8的几何中心在行方向上存在偏移情况，例如第一列(即B1列)，两个第一发光区6的中心相对第三发光区8的几何中心在行方向上存在偏移，而且偏移方向相反。
在一些示例性实施例中，如图9所示，上述按照一定规律排布的第一发光区6，呈矩阵排布的第二发光区7，呈阵列排布第三发光区8，第一发光区6和相邻的第二发光区7和第三发光区8可组合形成上述的多个第一像素单元19、多个第二像素单元21和多个第 三像素单元22。例如，处于第七行(即A7行)和第五列(即B5列)的一个第一发光区6，处于第八行(即A8行)和第四列(即B4列)的一个第二发光区7，处于第八行(即A8行)和第六列(即B6列)的一个第二发光区7，处于第九行(即A9行)和第五列(即B5列)的一个第三发光区8，四者和对应的开孔和围绕的非开口区构成一个第一像素单元19。又例如，同一个第一发光区6，即处于第七行(即A7行)和第五列(即B5列)的一个第一发光区6，处于第六行(即A6行)和第六列(即B6列)的一个第二发光区7，处于第八行(即A8行)和第六列(即B6列)的一个第二发光区7，处于第七行(即A7行)和第七列(即B7列)的一个第三发光区8，四者和对应的开孔和围绕的非开口区构成一个第三像素单元22。又例如，同一个第一发光区6，即处于第七行(即A7行)和第五列(即B5列)的一个第一发光区6，处于第六行(即A6行)和第四列(即B4列)的一个第二发光区7，处于第八行(即A8行)和第四列(即B4列)的一个第二发光区7，处于第七行(即A7行)和第三列(即B3列)的一个第三发光区8，四者和对应的开孔和围绕的非开口区构成一个第二像素单元21。
在一些示例性实施例中，如图9、图11至图13所示，上述指纹识别传感器9的投影对应第一像素单元19的投影(即第一像素投影15)中的非开口区5的投影布置，指纹识别传感器9的投影处于第一发光区和第三发光区的投影之间，可提升整体指纹识别传感器9放置均匀度。第一像素单元19的非开口区5的边缘由上述的第一像素开口10、第二像素开口11和第三像素开口12的边缘线及相邻的像素单元的边缘线围成，第一像素单元19的非开口区5在衬底基板1上的投影设置为第二投影14，第二投影14为第一像素投影15的一部分，第二投影14的边缘线为非开口边缘24，非开口边缘24包括首尾相接的五个第一边沿26，五个第一边沿26中的四个为弧形线，一个第一边沿26为直线。指纹识别传感器9在衬底基板1上的投影设置为第一投影13，第一投影13设置为与第二投影14一一对应且落在对应的第二投影14内。第一投影13相对于第二投影14居中布置，第一投影13的边缘线为传感器边缘23，传感器边缘23包括五个首尾相接的第二边沿25，五个第二边沿25中的四个为弧形线，一个第二边沿25为直线，四个为弧形线的第二边沿25和四个为弧形线的第一边沿26一一对应，而且四个为弧形线的第二边沿25和对应的第一边沿26同心且等距布置。一个为直线的第二边沿25与为直线的第一边沿26对应且平行。第一投影13的外轮廓与第二投影14的外轮廓匹配，第一投影13的外轮廓与第二投影14的外轮廓都为不规则图形，第一投影13的外轮廓与第二投影14的外轮廓都为类似梯形，使得第一投影13的面积可以最大化，提升开口率。第一投影13的形状并不限于此，第一投影13可为规则图形，例如第一投影13可为矩形、圆形、三角形等。由此，指纹识别传感器9在单位面积上的密度设置为P1，多个像素单元的像素密度设置为P2，其中，P1：P2＝1：1，显示效果优越而且指纹识别也更加有效。
在一些示例性实施例中，如图9、图14和图15所示，上述指纹识别传感器9的投影对应第二像素单元21的投影(即第二像素投影16)中的非开口区5的投影布置，指纹识别传感器9的投影处于第一发光区和第三发光区的投影之间，可提升整体指纹识别传感器9放置均匀度。第二像素单元21的非开口区5的边缘由上述的第一像素开口10、第二像素开口11和第三像素开口12的边缘线及相邻的像素单元的边缘线围成。第二像素单元21的非开口区5在衬底基板1上的投影设置为第三投影18，第三投影18为第一像素投影15的一部分，指纹识别传感器9在衬底基板1上的投影设置为第一投影13，第一投影13设置为与第三投影18一一对应且落在对应的第三投影18内。第一投影13相对于第三投影18居中布置，第一投影13的外轮廓与第三投影18的外轮廓匹配，第一投影13的外轮廓与第三投影18的外轮廓都为不规则图形，第一投影13的外轮廓与第三投影18的外轮廓都为类似梯形的形状，使得第一投影13的面积可以最大化，提升开口率。第一投影13 的形状并不限于此，第一投影13可为规则图形，例如第一投影13可为矩形、圆形、三角形等。由此，指纹识别传感器9在单位面积上的密度设置为P1，多个像素单元的像素密度设置为P2，其中，P1：P2＝1：2，显示效果优越而且指纹识别也更加有效。
在一些示例性实施例中，如图16至图19所示，上述指纹识别传感器9的投影对应第二像素单元21的投影(即第二像素投影16)中的非开口区5的投影布置。第二发光区7和第三发光区8的形状都为圆形。第一发光区6的形状不是圆形，第一发光区6包括第二图形20和第三图形28，第二图形20和第三图形28之间的接线为基准线c，基准线c沿第三方向延伸，在平行于衬底基板1的平面上，第三图形28的正投影的面积大于第二图形的正投影的面积，第二图形20呈半圆形，第三图形28呈半椭圆形，第二图形20的边缘中为直线的边沿为第二图形20的直线边沿，第三图形28的边缘中为直线的边沿为该第三图形28的直线边沿，第二图形20的直线边沿和第三图形28的直线边沿对应。由于第三图形28呈半椭圆形，使得第二像素单元21不根据基准线c对称，第二图形20在第二方向上的长度小于第三图形28在第二方向上的长度，相当于第一发光区6在第三图形28这一侧在第二方向上被拉伸，第二方向平行于衬底基板1且垂直于第三方向。在第二像素单元21中，第三图形28呈半椭圆形，也使得第一发光区6的投影(即第四投影27)上第三图形28的投影部分处于背向对应第二像素单元21的指纹识别传感器9的投影的一侧。在第二像素单元21构成的像素排列结构上，第三图形28的处于基准线c的一侧设置为与第一发光区6相对第三发光区在行方向或列方向的偏移一侧相同。由此，第一发光区6形成非对称轴设计，对应第一像素开口10也与第一发光区6相匹配而形成非对称轴设计，第一发光区6的形状可提升整体像素开口率，但第三图形28的外形并不限于为半椭圆形，例如也可为矩形等。
在一些示例性实施例中，全部的像素单元3可都为第一像素单元19，上述指纹识别传感器9对应第一像素单元19的非开口区5设置。或者，全部的像素单元3可都为第二像素单元21，上述指纹识别传感器9对应第二像素单元21的非开口区5设置。或者，全部的像素单元3可部分为第一像素单元19，部分为第二像素单元21，像素单元3不包括第三像素单元22，上述指纹识别传感器9对应第一像素单元19的非开口区5设置，或者对应第二像素单元21的非开口区5设置，或者对应第一像素单元19和第二像素单元21的非开口区5设置。或者，全部的像素单元3可都为第三像素单元22，上述指纹识别传感器9对应第三像素单元22的非开口区5设置。
在一些示例性实施例中，像素单元3和指纹识别结构2处于衬底基板1的不同侧，即指纹识别结构2处于衬底基板1在第一方向的一侧，像素单元3处于衬底基板1的另一侧。
在一些示例性实施例中，一种显示装置，包括上述的显示面板，显示装置可以是OLED显示器件。
结合上述实施例，显示面板的指纹识别结构2和像素单元3的排布结构，既可提高像素开口率，提升显示效果，而且还能提高指纹识别结构2的开口率，满足全屏指纹使用需求。指纹识别传感器9位于两个发光区的间隔处，可提升整体指纹识别传感器9放置均匀度。第一发光区6形成非对称轴设计，可提升整体像素开口率。
