下面接合附图和具体实施例对本申请做进一步的说明:
请参阅图1,图1为发明实施例提供的像素排列结构的结构示意图。本申请提供了一种像素排列结构100,包括多个沿横向、纵向或斜向重复排布的重复单元110,所述重复单元110包括相互独立的一个第一子像素111、一个第二子像素112、一个第三子像素113以及一个第四子像素114。
其中,同一所述重复单元110中的所述第一子像素111、所述第二子像素112、所述第三子像素113以及所述第四子像素114的中心点构成四边形。相邻重复单元110中四个相邻的子像素构成共享像素,所述共享像素至多包含归属于同一所述重复单元110中的两个子像素。
请参阅图2,图2为本申请实施例提供的像素排列结构中重复单元的结构示意图。在一种实施例中,一个所述重复单元110包括一个所述第一子像素111、一个所述第二子像素112、一个所述第三子像素113和一个第四子像素114。
以图1中行重复单元110为例进行说明,同一所述重复单元110包括一个第一子像素111、一个第二子像素112、一个第三子像素113和一个第四子像素114,能够形成一个完整的像素A1。第一行第一个重复单元110与所述第一行第二个重复单元110行方向上相邻,即第一行第一个重复单元110中的第二子像素112和第四子像素114与第一行第二个重复单元中的第一子像素111和第三子像素113形成一个共享像素。也就是说通过相邻重复单元110中相邻子像素共享,可以使得原本只能显示两个像素,通过相邻重复单元110之间的子像素共享,能够在感官上达到三个像素的感官效果,进而提高了显示装置的感官分辨率。同样的,在列方向的重复单元110,依旧可以通过上述原理实现显示装置感官分辨率的提高。
在一种实施例中,在每一行重复单元110中,假设重复单元110的个数为n,n为大于或者等于2的整数。通过共享子像素的结构,能够在感官上达到与设置有2n-1个像素A1的行像素结构相似的显示效果,进而相较于具有相同子像素排列密度的情况下,本申请中的显示装置能够达到更高的感官分辨率。
在一种实施例中,在每一列重复单元110中,假设重复单元110的个数为n,n为大于或者等于2的整数。通过共享子像素的结构,能够在感官上达到与设置有2n-1个像素的列像素结构相似的显示效果。
在一种实施例中,相邻重复单元110中四个相邻的子像素构成共享像素,所述共享像素包含归属于同一所述重复单元110中的两个子像素。
在一种实施例中,所述共享像素至多包含归属于同一所述重复单元110中的两个子像素为共享子像素。同一所述共享像素中的所述共享子像素为相邻设置或者对角线设置中的一者。
在一种实施例中,在横向和纵向方向上的相邻重复单元110形成的共享像素中,同一所述共享像素中的所述子像素为相邻设置。
在斜向方向上的相邻重复单元110形成的共享像素中,同一所述共享像素中的所述子像素为对角线设置。
在一种实施例中,所述第一子像素111和所述第四子像素114为颜色相同的子像素。所述第一子像素111的颜色、所述第二子像112素的颜色和所述第三子像素113的颜色互不相同。
在一种实施例中,所述第一子像素111的颜色、所述第二子像素112的颜色和所述第三子像素113的颜色与红色、绿色和蓝色一一对应。在实际操作中,技术人员可根据实际需求,进行第一子像素111的颜色、所述第二子像素112的颜色和所述第三子像素113的颜色与红色、绿色和蓝色对应的调整,即红色子像素、蓝色子像素和红色子像素的位置和数量可以根据实际情况进行布置。
在另一实施例中,为了实现相邻重复单元210之间形成共享,在像素排列结构200中,所述第一子像素211与所述第四子像素214沿对角线方向设置,所述第二子像素212和所述第三子像素213沿对角线方向设置。这样设置的目的在于,避免颜色相同的子像素相邻导致像素的显色效果较差。
在一种实施例中,请参阅图3,图3为本申请实施例提供的另一像素排列结构的结构示意图。所述第一子像素211和第四子像素214的颜色相同,所述第一子像素211、所述第二像素212、所述第三子像素213的颜色互不相同。具体的重复单元结构请参阅图4所示。
请参阅图4,图4为本申请实施例提供的另一像素排列结构的结构示意图。
在一种实施例中,请参阅图5,图5为本申请实施例提供的另一像素排列结构的结构示意图。所示第二子像素212和第三子像素213的颜色相同,所述第一子像素211、所述第二像素212、所述第四子像素214的颜色互不相同。具体的重复单元结构请参阅图6所示。
请参阅图6,图6为本发明另一像素排列结构中重复单元的结构示意图。
相较于现有的像素排列结构,本申请能够通过共享子像素的设置在保持相同感官分辨率不变的情况下降低对显示装置子像素的排列密度的要求。再者,由于分辨率较高的像素排列结构100需要高密度的精密金属掩膜板(Fine Metal Mask,简称FMM),高密度的精密金属掩膜板也是制约高分辨率技术发展的关键技术之一,随着显示装置的分辨率要求的提高,FMM的制作也越来越困难。另一方面,FMM张网时发生皱起的风险也逐渐提高,会直接影响OLED的生产质量。本申请通过能够通过共享子像素的设置在保持相同感官分辨率不变的情况下降低对显示装置子像素的排列密度的要求,也进一步的降低了FMM张网时的皱起风险。
在一种实施例中,所述第一子像素211和所述第四子像素214采用两个驱动电路分别驱动。通过采用两个驱动电路分别驱动颜色相同的第一子像素211和第四子像素214能够提升显示装置的显色效果。
在一种实施例中,所述第一子像素211和所述第四子像素214采用一个驱动电路共同驱动,通过上述设置能够简化显示装置的结构,节约显示装置的生产成本。可以理解的是,在重复单元中,能够采用同一个驱动电路共同驱动的子像素之间颜色相同。
当所述像素排列结构200中的子像素种类为四个时,所述第一子像素211的颜色、所述第二子像素212的颜色、所述第三子像素213的颜色和所述第四子像素214的颜色与红色、绿色、蓝色和白色一一对应。
在一种实施例中,所述第一子像素211、所述第二子像素212、所述第三子像素213和所述第四子像素214的形状包括多边形、圆形和椭圆形。
在一实施例中,请参阅图7,为本申请实施例提供的另一像素排列结构的结构示意图。所述第一子像素211、所述第二子像素212、所述第三子像素213和所述第四子像素214的形状位多边形。
根据本申请的另一个方面,还提供了一种显示装置,所述显示装置包括上述的像素排列结构。
所述显示装置的工作原理与所述像素排列结构的工作原理相似,所述显示装置的工作原理具体可以参考所述像素排列结构的工作原理,这里不做赘述。
本申请的优点是,提供了一种像素排列结构以及显示装置,通过采用相邻像素共用部分子像素的方式提升显示装置的感官分辨率,从而在具有相同子像素排列密度的情况下使显示装置达到更高的感官分辨率。
综上所述,虽然本申请已以优选实施例揭露如上,但上述优选实施例并非用以限制本申请,本领域的普通技术人员,在不脱离本申请的精神和范围内,均可作各种更动与润饰,因此本申请的保护范围以权利要求界定的范围为准。
