Description

显示面板及拼接面板 技术领域
本申请涉及显示技术领域，具体涉及一种显示面板及拼接面板。
 背景技术
在Mini/Micro LED面板的拼接技术中，通常采用红色列LED器件、绿色列LED器件和蓝色列LED器件沿着行向方向交替排布设置，或采用红色行LED器件01、绿色行LED器件02和蓝色行LED器件03沿着列向方向交替排布设置，如图1所示。但是，采用常规的像素排布时，由于LED器件上还会封装一层封装胶，使得最外围的LED器件发出的光线在封胶界面发生全反射，在拼接缝隙处造成侧视可见的彩色亮线，如图2所示。

本申请实施例提供一种显示面板及拼接面板，下文进行详细说明。需说明的是，以下实施例的描述顺序不作为对实施例优选顺序的限定。
请参照图3，本申请实施例提供一种显示面板100，其包括显示区AA。显示区AA包括中间区域A1和边缘区域A2，边缘区域A2设置在中间区域A1的相对侧或一侧。
本实施例以边缘区域A2设置在中间区域A1的相对侧为例；边缘区域A2的数量为两个，一边缘区域A2设置在中间区域A1的一侧，另一边缘区域A2设置在中间区域A1的另一侧；也即两个边缘区域A2之间隔着中间区域A1相对设置，如图3所示。
另外，在一些实施例中，边缘区域A2的数量可以是一个，一边缘区域A2可以设置在中间区域A1的任意一侧。
显示面板100包括基板11和多个像素12。像素12设置在基板11上。多个像素12包括多个第一像素1a和多个第二像素1b。
多个第一像素1a设置在中间区域A1。多个第二像素1b设置在边缘区域A2。第一像素1a包括多个发光颜色不同的第一发光器件1a1。第二像素1b包括多个发光颜色不同的第二发光器件1b1。
在第一方向X上，多个第一像素1a排布成像素行h。在与第一方向X相交的第二方向Y上，多个第一像素1a排布成第一像素排v1，多个第二像素1b排布成第二像素排v2。
显示区AA包括第一边缘w1和与第一边缘w1连接的第二边缘w2。第一边缘w1平行于第一方向X。第二边缘w2平行于第二方向Y。
在中间区域A1最靠近第一边缘w1的像素行h的第一像素1a中，多个第一发光器件1a1沿着第一方向X排布。在边缘区域A2最靠近第二边缘w2的第二像素排v2的第二像素1b中，多个第二发光器件1b1沿着第二方向Y排布。
第一发光器件1a1的长轴方向平行于第二方向Y，第一发光器件1a1的短轴方向平行于第一方向X。第二发光器件1b1的长轴方向平行于第一方向X，第二发光器件1b1的短轴方向平行于第二方向Y。
本申请实施例的显示面板100在显示区AA的第一边缘w1处设置有多个第一像素1a排列的像素行h。第一像素1a包括多个发光颜色不同的第一发光器件1a1，且第一发光器件1a1的长轴方向平行于第二方向Y；也即在第一边缘w1处的行方向上，相邻两个第一发光器件1a1的发光颜色不同；当显示面板100沿着第二方向Y拼接设置，拼接缝隙处的第一像素1a发出光经封装层13（见图4）的界面反射后，可以进行充分的混光，从而降低拼接缝隙处出现彩色亮线的风险。
在显示区AA的第二边缘w2处设置有多个第二像素1b排列的第二像素排v2。第二像素1b包括多个发光颜色不同的第二发光器件1b1，第二发光器件1b1的长轴方向平行于第一方向X。当显示面板100沿着第一方向X拼接设置，拼接缝隙处的第二像素1b发出光经封装层13的界面反射后，可以进行充分的混光，从而降低拼接缝隙处出现彩色亮线的风险。
因此，本实施例的显示面板100在第一边缘w1处和第二边缘w2处分别采用发光颜色不同的发光器件进行排列，降低了显示面板100在第一方向X和第二方向Y的拼接缝隙处出现彩色亮线的风险。
可选的，第一方向X与第二方向Y垂直设置；当然在一些实施例中，也可以是非垂直设置，比如呈30°、45°或60°倾斜设置等。
可选的，中间区域A1包括多行像素行h。边缘区域A2包括至少一排第二像素排v2。至少一排第二像素排v2沿着第一方向X间隔排布。其中，本实施例以边缘区域A2具有一排第二像素排v2为例，进行阐述。
另外，像素行h可以包括第二像素1b；也就是说，一行像素行h包括至少一个第二像素1b和多个第一像素1a。比如，一行像素行h包括两个第二像素1b和多个第一像素1a，一个第二像素1b设置在中间区域A1的一侧，另一第二像素1b设置在中间区域A1的另一侧。
可选的，第一像素1a的面积等于第二像素1b的面积。在第一方向X上和/或在第二方向Y上，相邻两个像素12的中心距离为像素间距d1，任意两个像素间距d1相等。
也就是说，上述的设置使得中间区域A1和边缘区域A2的像素间距d1一致，保证良好的显示效果。
可选的，第一像素1a包括红色的第一发光器件1a1、绿色的第一发光器件1a1和蓝色的第一发光器件1a1。第二像素1b包括红色的第二发光器件1b1、绿色的第二发光器件1b1和蓝色的第二发光器件1b1。
在第一方向X上，红色的第一发光器件1a1、绿色的第一发光器件1a1和蓝色的第一发光器件1a1依次间隔设置。
在第二方向Y上，多个红色的第一发光器件1a1排布呈列，多个绿色的第一发光器件1a1排布呈列，多个蓝色的第一发光器件1a1排布呈列；以及红色的第二发光器件1b1、绿色的第二发光器件1b1和蓝色的第二发光器件1b1依次间隔设置。
另外，在中间区域A1的第一方向X上，任意相邻的两个第一发光器件1a1的间距是相等的，第一发光器件1a1之间等间距设置。在边缘区域A2的第二方向Y上，任意相邻的两个第二发光器件1b1的间距是相等的，第二发光器件1b1之间等间距设置。
可选的，第一发光器件1a1和第二发光器件1b1分别可以是微型发光二极管（Micro-LED）或次毫米级发光二极管（Mini-LED）。
可选的，发光颜色相同的第一发光器件1a1和第二发光器件1b1的发光面积和形状相同。第一发光器件1a1和第二发光器件1b1的不同在于摆放的方向不同。比如将第一发光器件1a1旋转90°便为第二发光器件1b1。
也就是说，当一个发光器件水平竖向摆放时为第一发光器件1a1；当其水平横向摆放时为第二发光器件1b1。因此本实施例采用三种不同颜色的发光器件采用不同的摆放方式便可以实现上述像素12的排布，节省了发光器件种类需求，提高了转移效率。
可选的，第一像素1a的外轮廓形状与第二像素1b的外轮廓形状均为长方形。第一像素1a的长轴方向平行于第一方向X。第二像素1b的长轴方向平行于第二方向Y。
需要说明的是，虽然第一像素1a的长轴方向平行于第一方向X，但第一发光器件1a1的长轴方向垂直于第一方向X。同理，第二像素1b的长轴方向平行于第二方向Y，但第二发光器件1b1的长轴方向垂直于第二方向Y。
如此，第一像素1a的长轴由多个第一发光器件1a1的短轴组成，第二像素1b的长轴由多个第二发光器件1b1的短轴组成，使得第一像素1a和第二像素1b分别趋近于正方形，提高显示效果。
另外，当边缘区域A2只有少量的第二像素排v2时，最边缘的第一像素排v1距离显示区AA的第二边缘w2很近，因此第一像素排v1最边缘的纯色第一发光器件1a1也会提高彩色亮线的风险。而本实施例在相邻的第一像素1a和第二像素1b中，采用三个不同发光颜色的第二发光器件1b1设置在一个第一发光器件1a1的一侧，起到混光的效果，进一步降低了显示面板100进行拼接时，在拼接缝隙处出现彩色亮线的风险。
在一些实施例中，第一像素1a的外轮廓形状与第二像素1b的外轮廓形状均为正方形，请参照图4。当第一像素1a和第二像素1b为正方形时，使得整个显示区AA的像素12的分辨率一致，提高了显示效果。
请参照图5，显示面板100还包括封装层13。封装层13设置在基板11上且封装像素12。
可选的，封装层13的材料可以是透明的胶类材料。
在垂直于基板11所在平面的厚度方向Z上，封装层13对应覆盖像素12的部分的厚度为H，110微米≤H≤220微米。
在第一方向X上，封装层13的边缘到离其最近的第二发光器件1b1的距离为L1，140微米≤L1≤240微米。
可以理解的是，封装层13的厚度以及第二发光器件1b1到封装层13边缘的距离同样对彩色亮线存有影响。比如封装层13的厚度越薄，封装层13可提供的反射界面就越小，光线被反射的能量越小；第二发光器件1b1到封装层13侧面（全反射界面）的距离越大，第二发光器件1b1发出的光线随着距离的加大，辐射到界面的高度越高，以及光损加大，进而光线被反射的能量越小；从而可以降低从彩色亮线出现的风险。
但是封装层13的厚度越小，其封装效果就越差；第二发光器件1b1到封装层13侧面（全反射界面）的距离越大，越不利于窄边框。
因此，为了满足对发光器件（1a1和1b1）的封装效果、窄边框和封装层13侧面反射率的要求，发明人经过无限次的试验得到，当110微米≤H≤220微米，140微米≤L1≤240微米时，可以达到良好的效果。
可选的，H可以是110微米、130微米、150微米、170微米、190微米、200微米或220微米。L1可以是140微米、150微米、170微米、190微米、200微米、230微米或240微米。
可选的，在第二方向Y上，封装层13的边缘到离其最近的第一发光器件1a1的距离为L2，140微米≤L2≤240微米。比如，L2可以是140微米、150微米、170微米、190微米、200微米、230微米或240微米。
在另一实施例中，请参照图6，显示面板100还包括封装层13，封装层13设置在基板11上且封装像素12。在垂直于基板11所在平面的截面中，封装层13的侧面13a呈弧状。
也即跟上述实施例不同指出在于，封装层13的侧面13a设计为弧状。这样不仅可以减低封装层13的侧面13a的全反射率，而且可以调整光线的出射角度以分散光线，从而进一步降低了出现彩色亮线的风险；同时可以缩短L1和L2的长度，实现更窄边框。
在又一实施例中，请参照图7，跟上述各实施例的不同之处在于，显示面板100还包括封装层13和镀膜层14。封装层13设置在基板11上且封装像素12。镀膜层14形成在封装层13上，镀膜层14用于封装像素12。
封装层13的厚度大于镀膜层14的厚度。
可以理解的是，封装层13采用涂布工艺，由于工艺的限制使得封装层13的厚度较大。而镀膜层14采用的是镀膜工艺，比如气相沉积工艺和原子层沉积工艺；镀膜工艺可以实现低膜厚高防水氧的性能。
因此采用封装层13叠加镀膜层14的封装方式相较于仅采用封装层进行封装，可以薄化整体的封装厚度，进而降低彩色亮线的风险。
可选的，镀膜层14的材料可以是无机材料或有机材料。
请参照图8，相应的，本申请实施例还提供一种拼接面板1000，其包括至少两个如上述任意一个实施例的显示面板100。至少两个显示面板100沿着第一方向X和/或第二方向Y拼接设置。
可选的，相邻两个显示面板100拼接形成有拼接缝隙fx。间隔拼接缝隙fx且相对设置的两个第二发光器件1b1发出的颜色光相同。
这样的设置使得拼接缝隙fx处一一相对设置的第二发光器件1b1的光损失一致，提高显示效果。
在一些实施例中，拼接缝隙fx处一一相对设置的第二发光器件1b1的发光颜色也可以不同。
其中，本实施例以4个显示面板100沿着第一方向X和第二方向Y拼接设置为例。
在第一方向X上，两个显示面板100拼接形成有拼接缝隙fx1；在第二方向Y上，两个显示面板100拼接形成有拼接缝隙fx2。在拼接缝隙fx1处，一一相对的第二发光器件1b1的发光颜色相同；在拼接缝隙fx2处，一一相对的第一发光器件1a1的发光颜色相同。
本申请实施例的拼接面板1000中的显示面板100在显示区AA的第一边缘w1处设置有多个第一像素1a排列的像素行h。第一像素1a包括多个发光颜色不同的第一发光器件1a1，且第一发光器件1a1的长轴方向平行于第二方向Y；也即在第一边缘w1处的行方向上，相邻两个第一发光器件1a1的发光颜色不同；当显示面板100沿着第二方向Y拼接设置，拼接缝隙处的第一像素1a发出光经封装层13（见图4）的界面反射后，可以进行充分的混光，从而降低拼接缝隙处出现彩色亮线的风险。
在显示区AA的第二边缘w2处设置有多个第二像素1b排列的第二像素排v2。第二像素1b包括多个发光颜色不同的第二发光器件1b1，第二发光器件1b1的长轴方向平行于第一方向X。当显示面板100沿着第一方向X拼接设置，拼接缝隙处的第二像素1b发出光经封装层13的界面反射后，可以进行充分的混光，从而降低拼接缝隙处出现彩色亮线的风险。
因此，本实施例的拼接面板1000在第一边缘w1处和第二边缘w2处分别采用发光颜色不同的发光器件进行排列，降低了拼接面板1000在第一方向X和第二方向Y的拼接缝隙处出现彩色亮线的风险。
以上对本申请实施例所提供的一种显示面板及拼接面板进行了详细介绍，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方法及其核心思想；同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
