请结合参照图1至图3，图1为本申请实施例提供的显示面板的一种俯视结构示意图，图2为本申请实施例提供的显示面板的剖面结构示意图，图3为本申请实施例提供的显示面板的部分细节结构示意图。所述显示面板100包括基板10和排布在所述基板10上的多个像素（如图1示出的第一像素20-1、第二像素20-2、第三像素20-3以及第四像素20-4）。每个所述像素至少包括间隔排布的三个不同颜色的发光单元（如图1示出的发光单元R、G、B）。其中，任意两个相邻的所述像素中，一个所述像素的一个所述发光单元与另一个所述像素的一个相邻的所述发光单元的颜色相同。
具体地，所述显示面板100还包括阵列排布在所述基板10上的第一电极30和像素定义层40。所述像素定义层40覆于所述基板10以及所述第一电极30上，并在对应所述第一电极30处形成有像素开口401，所述像素开口401裸露出对应的所述第一电极30。每个所述发光单元设置于一个所述像素开口401内。
具体地，所述基板10包括衬底11以及设置在所述衬底11上的驱动电路层12。可选地，所述衬底11和所述驱动电路层12之间还可设置缓冲层13，所述缓冲层13的材料可包括氧化硅（SiOx）、氮化硅（SiNx）、氮氧化硅（SiON）等无机材料，所述缓冲层13可以进一步防止不期望的杂质或污染物（例如湿气、氧气等）从所述衬底11扩散至可能因这些杂质或污染物而受损的器件中，同时还可以提供平坦的顶表面。
可选地，所述衬底11可以为刚性基板或柔性基板；所述衬底11为刚性基板时，可包括玻璃基板10等硬性基板；所述衬底11为柔性基板时，可包括聚酰亚胺（Polyimide，PI）薄膜、超薄玻璃薄膜等柔性基板，采用柔性基板作衬底11可以制作柔性显示面板，以实现显示面板100的弯折、卷曲等特殊性能。
所述驱动电路层12包括依次层叠设置在所述缓冲层13上的有源层121、栅极绝缘层122、栅极123、层间绝缘层124、源漏极层125、钝化层126以及平坦化层127。所述有源层121包括沟道区1211以及位于所述沟道区1211两侧的源极区1212和漏极区1213。所述栅极绝缘层122覆于所述有源层121，并对应所述沟道区1211设置。所述栅极123设置与所述栅极绝缘层122上，且所述栅极123与所述沟道区1211对应设置。
可选地，所述基板10还包括遮光层14，所述遮光层14设置于所述衬底11上，所述缓冲层13覆于所述遮光层14以及所述衬底11上。所述遮光层14对应所述有源层121设置，使得所述有源层121在所述衬底11上的正投影落在所述遮光层14在所述衬底11上的正投影范围内，也即所述遮光层14能够完全遮挡所述有源层121，避免光线照射所述有源层121。
所述层间绝缘层124覆于所述栅极123以及所述缓冲层13上，所述源漏极层125设置于所述层间绝缘层124上，所述源漏极层125图案化形成源极1251、漏极1252等，所述源极1251通过所述层间绝缘层124的过孔与所述源极区1212连接，所述漏极1252通过所述层间绝缘层124的另一过孔与所述漏极区1213连接。
所述钝化层126覆于所述源漏极层125以及所述层间绝缘层124上，所述平坦化层127覆于所述钝化层126上。设置所述平坦化层127可为所述基板10提供平坦的膜层表面。
需要说明的是，本申请驱动电路层12的结构不限于本实施例示意的，本申请的驱动电路层12还可包括更多或更少的膜层，且各膜层的位置关系也不限于本实施例示意的，比如所述栅极123还可位于所述有源层121的下方，形成底栅结构。
所述第一电极30阵列排布在所述平坦化层127上，每个所述第一电极30通过所述平坦化层127以及所述钝化层126的过孔与所述源极1251或所述漏极1252连接，本申请以所述第一电极30与所述漏极1252连接为例说明。
可选地，所述第一电极30可以是透明电极或反射电极，如果所述第一电极30是透明电极，则所述第一电极30可以由例如氧化铟锡(ITO)、氧化铟锌(IZO)、ZnO或In2O3形成。如果所述第一电极30是反射电极，则所述第一电极30例如可以包括由Ag、Mg、Al、Pt、Pd、Au、Ni、Nd、Ir、Cr或它们的组合形成的反射层以及由ITO、IZO、ZnO或In2O3形成的层。然而，第一电极30不限于此，第一电极30可以由各种材料形成，并且也可以形成为单层或多层结构。
所述像素定义层40覆于所述第一电极30以及所述平坦化层127上，所述像素定义层40图案化形成有像素开口401。每个所述像素开口401对应一个所述第一电极30，并裸露出部分所述第一电极30，以定义出所述发光单元的设置区域。所述发光单元设置在所述像素开口401内，并覆于所述像素开口401内的所述第一电极30上。
其中不同颜色的所述发光单元是把不同颜色的发光材料打印在所述像素开口401内形成，具体而言，把不同颜色的发光材料分别溶融在不同的有机溶液中，形成不同颜色的墨水，然后采用喷墨打印等工艺把不同颜色的墨水分别打印在不同的所述像素开口401内以形成不同颜色的所述发光单元。不同颜色的发光材料发射不同颜色的光，比如红色发光材料发射红光，绿色发光材料发射绿光，蓝色发光材料发射蓝光，使得形成的不同颜色的发光单元发射不同颜色的光。
具体地，三个不同颜色的所述发光单元分别为第一颜色发光单元B、第二颜色发光单元R以及第三颜色发光单元G，其中所述第一颜色发光单元B为蓝色发光单元，蓝色发光单元发射蓝光；所述第二颜色发光单元R为红色发光单元，红色发光单元发射红光；所述第三颜色发光单元G为绿色发光单元，绿色发光单元发射绿光。其中所述第一颜色发光单元B、所述第二颜色发光单元R以及所述第三颜色发光单元G的表面形状均为三角形，但本申请不限于此，本申请的所述发光单元的表面形状还可为其他规则或不规则图形。
由于每个所述像素均包括至少三个不同颜色的发光单元，也即每个所述像素均包括第一颜色发光单元B、第二颜色发光单元R以及第三颜色发光单元G，使得每个所述像素均可显示各种颜色，进而使得所述显示面板100实现彩色显示。
可以理解的是，为了使所述发光单元发光，所述显示面板100还包括设置在所述发光单元以及所述像素定义层40上的第二电极60。所述发光单元在所述第一电极30和所述第二电极60的共同作用下发光，不同颜色的发光单元发射不同颜色的光，进而实现所述显示面板100的全彩显示。其中本申请实施例的所述第一电极30为阳极，所述第二电极60为阴极，当然地，本申请不限于此，本申请的所述第一电极30也可为阴极，而相应地，所述第二电极60为阳极。
可选地，为了提高光线的透过率，所述第二电极60采用透明导电材料形成。例如所述第二电极60可由ITO、IZO、ZnO或In2O3等透明导电氧化物（Transparent Conductive Oxide，TCO）形成。
另外可选地，所述显示面板100还可包括设置于所述发光单元与所述第一电极30之间的空穴注入层(HIL)、空穴传输层(HTL)；以及设置于所述发光单元与所述第二电极60之间的电子注入层(EIL)、电子传输层(ETL)。空穴注入层接收第一电极30传输的空穴，空穴经由空穴传输层传输至发光单元，电子注入层接收第二电极60传输的电子，电子经由电子传输层传输至发光单元，空穴和电子在发光单元位置结合后产生激子，激子由激发态跃迁至基态释放能量并发光。
再者，为了保护所述发光单元，避免水氧入侵导致发光单元失效，所述显示面板100还包括设置所述第二电极60上的封装层70。可选地，所述封装层70可采用薄膜封装，比如所述封装层70可以为由第一无机封装层、有机封装层、第二无机封装层三层薄膜依次层叠形成的叠层结构或更多层的叠层结构。
另外，由于每相邻的两个所述像素之间，相邻的两个所述发光单元的颜色相同，从而能够避免相邻的所述像素之间发生混色，提高显示品质。下面将详细阐述如何使相邻的所述像素之间，相邻的所述发光单元的颜色相同：
可选地，所述显示面板100包括沿第一方向X依次顺序排布的第一像素单元组1和第二像素单元组2，使得所述第一像素单元组1和所述第二像素单元组2在沿所述第一方向X上交替排布，其中相邻的所述第一像素单元组1和所述第二像素单元组2轴对称。所述第一像素单元组1和所述第二像素单元组2均包括两个所述像素。在所述第一像素单元组1内和所述第二像素单元组2内，两个所述像素中心对称。
可选地，每个所述像素的三个不同颜色的所述发光单元的形状均为三角形，每个所述发光单元均包括两个短边和一个长边，所述长边的边长大于所述短边的边长，且在每个所述像素内，各所述发光单元的两个所述短边形成的顶点彼此靠近，各所述发光单元的所述长边的延长线围成等腰三角形，也即每个所述像素的形状为等腰三角形，如此由两个互为中心对称的所述像素形成的所述第一像素单元组1和所述第二像素单元组2的形状均为菱形。
具体而言，所述第一像素单元组1包括第一像素20-1和第二像素20-2，所述第一像素20-1和所述第二像素20-2互为中心对称，且所述第一像素20-1和所述第二像素20-2的形状均为等腰三角形。所述第二像素单元组2包括第三像素20-3和第四像素20-4，所述第三像素20-3和所述第四像素20-4互为中心对称，且所述第三像素20-3和所述第四像素20-4的形状均为等腰三角形。而且由于相邻的所述第一像素单元组1和所述第二像素单元组2轴对称，则对于相邻的所述第一像素单元组1和所述第二像素单元组2，所述第一像素单元组1内的所述第一像素20-1与所述第二像素单元组2内的所述第三像素20-3轴对称，所述第一像素单元组1内的所述第二像素20-2与所述第二像素单元组2内的所述第四像素20-4轴对称。
进一步地，在第二方向Y上，所述第一像素单元组1和所述第二像素单元组2均阵列排布。具体而言，在沿所述第二方向Y上，所述第一像素单元组1和所述第二像素单元组2不相邻。也即在所述第二方向Y上，所述第一像素单元组1单独排布成一行，所述第二像素单元组2也单独排布成一行，所述第一像素单元组1与所述第二像素单元组2位于不同行。需要说明的是，本申请的所述第一方向X可以为竖直方向，所述第二方向Y为水平方向，所述第一方向X与所述第二方向Y垂直，当然地，本申请不限于此，本申请的所述第一方向X也可为水平方向，所述第二方向Y为竖直方向，且所述第一方向X和所述第二方向Y还可为其他夹角。
由于所述第一像素单元组1和所述第二像素单元组2在所述第二方向Y上均阵列排布，且所述第一像素单元组1内两个所述像素和所述第二像素单元组2内的两个所述像素均互为中心对称，使得在沿所述第二方向Y上，任意相邻的两个所述像素互为中心对称。同时由于在所述第一方向X上，相邻的所述第一像素单元组1和所述第二像素单元组2轴对称，如此使得任意相邻的两个所述像素之间，相邻的所述发光单元的颜色相同。这样在采用喷墨打印工艺打印所述发光单元时，由于相邻的两个所述像素之间，相邻的所述发光单元的颜色相同，即使由于喷墨打印设备的喷头精度有限，存在误差，可能导致打印方向变化从而将该墨水打入相邻发光单元，也不会造成像素之间的混色。
然而可以理解的是，由于同一所述像素内，相邻的所述发光单元颜色是不同的，这使在像素内还是存在混色的风险。为了避免同一所述像素内相邻所述发光单元之间混色，可在同一所述像素内相邻的所述发光单元之间设置阻挡层50，以阻挡墨水打入相邻的发光单元坑内。
具体而言，所述阻挡层50设置在所述像素定义层40远离所述基板10的一侧，且位于相邻的两个颜色不同的所述发光单元之间。所述阻挡层50的材料为疏水性材料，比如疏水性材料可以是由通过对有机光阻材料进行制程处理使其表面聚集氟离子而形成。通过在相邻的两个颜色不同的所述发光单元之间设置阻挡层50，增高了所述发光单元间的阻隔层高，使得即使发生喷头打印偏差，所述阻挡层50仍然可以阻挡偏离的墨滴使之最终流入目标发光单元坑内。同时所述阻挡层50采用疏水性材料，当打入发光单元坑内的墨滴较多，所述阻挡层50的疏水性导致的表面张力能保证墨滴依然在该发光单元坑内，避免产生溢流。
在一种实施例中，请结合参照图1至图4，图4为本申请实施例提供的显示面板的另一种俯视结构示意图。与上述实施例不同的是，本实施例的显示面板101上，在第二方向Y上，所述第一像素单元组1和所述第二像素单元组2交替排布。同时在所述第一方向X上，所述第一像素单元组1和所述第二像素单元组2也交替排布，如此每一所述第一像素单元组1与四个所述第二像素单元组2相邻，相对应地，每一所述第二像素单元组2也同样与四个所述第一像素单元组1相邻。而且在所述第一方向X上，相邻的所述第一像素单元组1和所述第二像素单元组2轴对称，在所述第二方向Y上，相邻的所述第一像素单元组1和所述第二像素单元组2同样轴对称。此时同样能使相邻的两个所述像素之间，相邻的两个所述发光单元的颜色相同。
具体而言，在所述第一像素单元组1和所述第二像素单元组2内，每个所述像素的三个不同颜色的所述发光单元的形状均为三角形，每个所述发光单元均包括两个短边和一个长边，所述长边的边长大于所述短边的边长，且在每个所述像素内，各所述发光单元的两个所述短边形成的顶点彼此靠近，各所述发光单元的所述长边的延长线围成直角三角形，也即每个所述像素的形状为直角三角形。如此由两个互为中心对称的所述像素形成的所述第一像素单元组1和所述第二像素单元组2的形状均为方形，比如长方形或正方形。
另外，还与上述实施例不同的是，在同一所述像素内，所述第一颜色发光单元B的面积大于所述第二颜色发光单元R的面积，且大于所述第三颜色发光单元G的面积。所述第一颜色发光单元B为蓝色发光单元，而蓝色发光材料的发光效率和寿命相较于其他颜色发光材料的发光效率和寿命差，故在每个所述像素内，设置较大面积的蓝色发光单元，能够提高所述显示面板101的使用寿命。其他说明请参照上述实施例，在此不再赘述。
在一种实施例中，请结合参照图1至图5，图5为本申请实施例提供的显示面板的又一种俯视结构示意图。与上述实施例不同的是，在所述显示面板102内，在所述第一方向X上，相邻的所述第一像素单元组1和所述第二像素单元组2中心对称。在第二方向Y上，多个所述第一像素单元组1阵列排布；在所述第二方向Y上，多个所述第二像素单元组2也阵列排布。
具体而言，每个所述第一像素单元组1包括第一像素20-1和第二像素20-2，所述第一像素20-1和所述第二像素20-2互为中心对称。每个所述第二像素单元组2包括第三像素20-3和第四像素20-4，所述第三像素20-3和所述第四像素20-3互为中心对称。同时在所述第一方向X上，任意相邻的所述第一像素单元组1和所述第二像素单元组2也互为中心对称，在所述第二方向Y上，任意相邻的所述第一像素单元组1和所述第二像素单元组2也同样互为中心对称。如此所述第一像素单元组1和所述第二像素单元组2的结构完全相同，也即所述第一像素单元组1和所述第二像素单元组2内各发光单元的排布形态完全相同，这样在满足相邻的两个所述像素之间，相邻的所述发光单元的颜色相同外，还能简化工艺。其他说明请参照上述实施例，在此不再赘述。
基于同一发明构思，本申请实施例还提供一种电子装置，所述电子装置包括前述实施例其中之一的显示面板100。所述电子装置可以为手机、电视、平板、可穿戴显示设备等电子显示产品。
根据上述实施例可知：
本申请提供一种显示面板和电子装置，该显示面板包括基板以及沿第一方向交替排布在所述基板上的多个第一像素单元组和多个第二像素单元组，每个所述第一像素单元组和每个所述第二像素单元组均包括两个互为中心对称的像素，每个所述像素至少包括间隔排布的三个不同颜色的发光单元，任意两个相邻的所述像素之间，一个所述像素的一个所述发光单元与另一个所述像素的一个相邻的所述发光单元的颜色相同。本申请通过使相邻两个像素之间相邻的发光单元颜色相同，如此在采用喷墨打印工艺打印发光单元时，能够避免像素之间的混色，从而解决了现有OLED器件存在的像素间混色的问题。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上对本申请实施例进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
