Description

显示器 技术领域
本发明涉及一种显示器，尤其涉及一种具有条形像素定义层的显示器。
 背景技术
喷墨打印的加工方法能高效利用材料，适合制备大面积显示面板。参见图1，图1为当前普遍采用的传统面板100的像素设计示意图，其为肩靠肩(side-by-side, SBS)设计，即每个像素110由独立的子像素111规律排列而成，子像素111之间由像素定义层120相互隔离开。一般喷墨打印像素的尺寸大小约为200 um * 200 um（取决于屏幕尺寸和分辨率），子像素要求则更小，喷墨打印的墨滴直径约为30 um。对于喷墨打印而言，对这样的像素进行打印则要求打印机具有极高的打印精度、移动精度和精准的墨滴控制能力，不容许出现相邻像素内墨水出现误打印、漏打印、墨水桥联的现象，否则将导致膜厚不均匀，发光层打印时桥连将出现混色问题。四倍全高清分辨率的子像素数量为3940*2160*3个，在千万级别以上。即使百万分之一的打印异常概率亦将导致整个面板的坏点像素数超出通常规格容许范围（≤3个），所以传统面板的SBS像素设计理念很难满足高分辨率的面板制备需求。
 技术问题
为了解决制备传统面板时像素打印不精准的问题，亟需开发一种可提高打印的成功率的新像素设计，其具有较大的像素定义层开口，扩大打印区域，以解决目前对墨滴着弹精度和墨滴控制系统要求严苛的情况，提高打印的成功率。
 技术解决方案
有鉴于此，本发明提供一种显示器，包括一种崭新的像素设计，将长轴或者短轴方向上部分像素合并，形成条形像素定义层开口，藉此扩大打印区域，以解决目前对墨滴着弹精度和墨滴控制系统要求严苛的情况，提高了打印的成功率。
据此，依据本发明的一实施例，本发明提供了一种显示器，其特征在于，包括：像素定义层，具有多个条形开口，所述多个条形开口至少排成两列或至少排成两行且彼此平行；以及多个子像素，其中至少两个相邻的所述子像素配置于每一个所述条形开口中。
在本发明的一实施例中，所述像素定义层为一层、双层、或多层结构。
在本发明的一实施例中，所述多个条形开口的延伸方向皆沿着显示器的短轴方向。
在本发明的一实施例中，所述多个条形开口的延伸方向皆沿着显示器的长轴方向。
在本发明的一实施例中，配置于同一个条状开口中的至少两个相邻的所述子像素为同行相邻的子像素或同列相邻的子像素，且两个相邻的所述子像素的颜色相同或相异。在本发明的一实施例中，所述显示器在像述定义层下方更包括：基板；多个电极，位于所述基板之上，其中所述条形开口露出所述多个电极。
在本发明的一实施例中，所述显示器更包括：多个薄膜晶体管，设置于所述多个电极与所述基板之间。
在本发明的一实施例中，所述显示器更包括多个条形像素，其中所述多个条形像素中之一者是由所述多个子像素中至少两个相邻的子像素所构成，所述多个条形像素至少排列成两列且彼此平行。
在本发明的一实施例中，所述显示器更包括多个条形像素，其中所述多个条形像素中之一者是由所述多个子像素中至少两个相邻的子像素所构成，所述多个条形像素至少排列成两行且彼此平行。在本发明的一实施例中，所述像素定义层包括一有机材料。
在本发明的一实施例中，所述有机材料包括下列至少一者：聚酰亚胺、亚克力、以及酚醛树脂。

根据本发明的一实施例，在步骤S10中，利用刻蚀开槽所述像素定义层，使所述像素定义层具有多个条形开口以露出位于所述像素定义层下方的多个电极；以及在步骤S20中，利用喷墨打印制程将多个子像素喷涂于所述多个条行开口中。
