Description

像素排列结构及OLED显示装置 技术领域
本申请涉及显示技术领域，尤其涉及一种像素排列结构及OLED显示装置。
 背景技术
有机发光二极管(Organic Light Emitting Display，OLED)显示装置具有自发光、驱动电压低、发光效率高、响应时间短、清晰度与对比度高、近180°视角、使用温度范围宽，可实现柔性显示与大面积全色显示等诸多优点，被业界公认为是最有发展潜力的显示装置。
随着显示技术的发展，人们对于显示设备的分辨率以及亮度的要求越来越高，但要制作高分辨率的OLED显示屏就需要更高精度的金属掩膜板FMM(Fine Metal Mask)，因为，通常的条状子像素(RGB stripe)构成的像素中，在垂直于子像素条方向的方向上一个像素间距内要安排三个子像素，在像素密度高于300ppi（pixels per inch，每英寸的像素数量）时，现阶段FMM工艺实现起来非常困难。同时，由于分辨率的提高，子像素发光区域之间的距离要求越来越小，蒸镀出来的屏幕混色也会越来越严重，特别是传统的条状排列的红(R)、绿(G)、蓝(B)三个子像素，每个子像素对应的FMM的开口区域的长度较长，直线性控制困难，容易发生混色，传统的RGB strip像素结构如果直接应用在OLED面板上存在分辨率不能提高，制作难度大的问题。
综上所述，现有的像素排列结构及OLED显示装置，使用条状子像素(RGB stripe)构成的像素排列结构，难以实现高分辨率产品的制备，且存在制作难度大的技术问题。

 本发明的实施方式
在实现高分辨率高PPI的技术中，传统的RGB strip排列方式已经遇到了布线空间不足、良率低、开口率小等问题。尤其OLED显示装置在因打印设备精度和工艺的限制下，对高PPI产品打印存在困难。业界不同厂商针对性的提出了各自Pixel SPR（Sub Pixel Rendering）技术方案，并在手机电视等屏中得到了大量的运用。SPR是一种像素渲染技术（Sub Pixel Rendering)。每个主像素由两个子像素构成，它们以“红+绿”或“绿+蓝”或“蓝+红”顺序周期排列而成。可以提高产品PPI，降低驱动IC通道数，提高产品开口率，减少产品功耗。
但现行的SPR技术方案，因RGB子画素在横向、竖向、斜列方向均不成列，故并不适合未来量产OLED打印工艺--Line Bank技术。本申请实施例针对现有的像素排列结构及OLED显示装置，使用条状子像素(RGB stripe)构成的像素排列结构，难以实现高分辨率产品的制备，且存在制作难度大的技术问题，本实施例能够解决该缺陷。

具体地，相对于传统条状子像素(RGB stripe)构成的像素排列结构应用于接线排打印工艺（Line Bank）来说，打印移动的方向D3，由原来传统条状子像素(RGB stripe)构成的像素排列结构平行于基板长短边，改为与基板长短边成45°角进行，从头打到尾。即，所述接线排打印工艺（Line Bank）中打印针头的移动方向D3与承载基板40的短边的夹角成45°。
本申请实施例提供的像素排列结构，属于一种新的OLED像素素SPR 排布架构设计，在实现了高分辨率产品制备的同时，兼容了未来OLED打印量产技术——接线排打印工艺（Line Bank）。
本发明的实施例还提供一种OLED显示装置，所述OLED显示装置包括上述的像素排列结构。
本申请实施例所提供的像素排列结构及OLED显示装置，将同一种颜色的子像素在斜线方向成一列，在实现了高分辨率产品的同时，兼容了OLED打印量产的接线排打印工艺技术。
以上各个操作的具体实施可参见前面的实施例，在此不再赘述。
综上所述，本申请实施例所提供的像素排列结构及OLED显示装置，在不增加掩膜版及工艺流程的前提下，避免了柔性显示面板在切割过程中因无机层延展性较差而在弯折过程产生的裂纹，进一步的确保了柔性显示面板的显示性能。
可以理解的是，对本领域普通技术人员来说，可以根据本申请的技术方案及其发明构思加以等同替换或改变，而所有这些改变或替换都应属于本申请所附的权利要求的保护范围。
