本实施例中,在图1中提供的所述像素排列结构10的基础上,提供一种像素共用的驱动方法。该方法可以使得各个子像素沿着所述第一方向形成子像素单元,并且在子像素单元之间存在子像素的共用。像素共用之后可以增大单位面积的像素密度,实现显示面板中较高的分辨率。在一个实施例中,所述第一方向上可以设置为Y 3=X 3。在形成显示面板时,
Figure PCTCN2020086827-appb-000003
或者
Figure PCTCN2020086827-appb-000004
其中pitch为显示面板的第一方向或第二方向的尺寸与对应方向的分辨率的比值。这样在物理结构上排列较少的子像素,就可以实现较高分辨率的像素显示。

所述基板21具有对位边201,当所述像素排列结构10设置于所述基板21时,所述第二边103和所述对位边之间具有大于0°且小于360°的夹角。在一个实施例中,所述第二边103和所述对位边201之间的夹角为90°、180°或270°。
本实施例中,可以根据所述显示面板20的形状和结构来设置所述像素排列结构10中所述第二边103和所述对位边201之间的夹角。也可以说,根据所述显示面板20的形状和结构来设置所述像素排列结构10的旋转角度。另外可以理解,在本申请的图1-图6中所述像素排列结构10中,各个子像素之间的间距可以不按照图中的距离关系进行设置。图1至图6仅仅表示出一个像素单元中四个子像素的相对位置关系。
本申请进一步提供一种像素排列结构的制备方法,包括:提供基板21;在基板21上沉积薄膜晶体管(TFT);在薄膜晶体管的表面沉积阳极(Anode);在阳极(Anode)的表面沉积有机发光单元和像素限定层(作为子像素)。在沉积有机发光单元和像素限定层的时候可以按照本申请中图1至图6给出的像素排列结构进行沉积。
本申请中子像素外侧的框线并不存在实际意义,仅仅是示意性的,是用于更清楚地说明各子像素的排布位置,在制作显示面板的过程中,并不会制作这样的框线。以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的实施方式,其描述较为具体和详细,但并不能因此而理解为对发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本申请构思的前提下,还可以做出若干变形和改进,这些都属于本申请的保护范围。因此,本申请专利的保护范围应以所附权利要求为准。
