本发明的实施方式
下面结合附图和实施例,对本申请作进一步地详细描述。特别指出的是,以下实施例仅用于说明本申请,但不对本申请的范围进行限定。同样的,以下实施例仅为本申请的部分实施例而非全部实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例,都属于本申请保护的范围。
在有机发光二极管(Organic Light-Emitting Diode,OLED)全彩化方法中,红(R)、绿(G)、蓝(B)三基色像素通常采用pentile排列,以解决红绿蓝有机发光材料的寿命与效率存在差异的问题,但是,在实际显示图像时,pentile排列的一个像素点会“借”用与其相邻的像素点的另一种颜色来构成三基色,以共同实现白色显示,这会导致分辨率偏低、彩边以及边缘锯齿化的问题。为了解决上述技术问题,本申请采用的技术方案是提供一种发光器件,以避免由于不同像素单元之间共用子像素而造成分辨率偏低、彩边和边缘锯齿化的问题。
请参阅图1,图1是本申请实施例提供的发光器件的结构示意图。如图1所示,该发光器件10包括基板(图中未示出)、以及位于基板上的呈阵列排布的多个像素单元11。其中,像素单元11包括间隔设置的第一基色光子像素111、第二基色光子像素112和第三基色光子像素113。在每一像素单元11中,第一基色光子像素111、第二基色光子像素112和第三基色光子像素113组合后呈圆形,且第一基色光子像素111、第二基色光子像素112和第三基色光子像素113的面积不完全相等。
具体地,第一基色光子像素111、第二基色光子像素112和第三基色光子像素113的面积与其对应的子像素寿命成反比,以减小不同子像素之间的使用寿命差异,进而延长发光器件的寿命。
例如,在一个实施例中,第一基色光子像素111可以为红光子像素,第二基色光子像素112可以为绿光子像素,第三基色光子像素113可以为蓝光子像素。由于红绿蓝有机发光材料的寿命存在差异,且通常蓝色有机发光材料的寿命短于红色有机发光材料的寿命,红色有机发光材料的寿命短于绿色有机发光材料的寿命,也即蓝光子像素的寿命低于红光子像素的寿命,红光子像素的寿命低于绿光子像素的寿命,因此,可以对应设置蓝光子像素的面积大于红光子像素的面积,红光子像素的面积大于绿光子像素的面积。
在本实施例中,第一基色光子像素111、第二基色光子像素112和第三基色光子像素113组合后呈圆形,能够避免在实际显示时出现彩边和边缘锯齿化现象。例如,如图2所示,发光器件10的像素单元11在显示字母“A”时,单个像素单元内的三个基色光子像素111/112/113同时发光,呈现白色,字母“A”边缘平滑,不会出现彩边和边缘锯齿化现象,视觉效果相对于pentile型子像素排列有很大提高。
值得注意的是,上述三种基色光子像素111/112/113组合后呈圆形,是指整体上呈圆形,在一些实施例中,还可以是呈椭圆形,或呈接近圆形的多边形。
具体地,请继续参阅图1,每一像素单元11与相邻的多个像素单元11之间相互间隔,同一像素单元11内的第一基色光子像素111、第二基色光子像素112和第三基色光子像素113之间相互间隔。其中,相邻像素单元11之间间隔距离越小,对应的显示分辨率越高。同理,相邻基色光子像素111/112/113之间也是如此。
在一个实施例中,如图1所示,第一基色光子像素111、第二基色光子像素112和第三基色光子像素113的形状可以均为扇形。具体地,三种基色光子像素111/112/113对应的圆心角之和为360度,且三种基色光子像素111/112/113对应的圆心角大小与其对应的子像素寿命成反比。例如,第一基色光子像素111为红光子像素,其对应的圆心角范围可以为90~120度,第二基色光子像素112为绿光子像素,其对应的圆心角范围可以为60~90度,第三基色光子像素113为蓝光子像素,其对应的圆心角范围可以为150~180度,如此,以减小红绿蓝三种子像素发光材料之间的寿命差异,进而延长发光器件的寿命。
在另一个实施例中,如图3和图4所示,像素单元11还可以包括至少一个补偿光子像素114。其中,在每一像素单元11中,第一基色光子像素111、第二基色光子像素112和第三基色光子像素113构成一个整体上呈圆形的基色光子像素组A,且补偿光子像素114位于该基色光子像素组A的周边区域,如此,补偿光子像素114与相邻的基色光子像素组A构成具有四个子像素的像素单元11,不仅能提升画面显示的亮度和色彩度,有效节省能耗,延长发光器件的使用寿命,还能够提高发光器件的像素开口率。
具体地,补偿光子像素114可以位于由相邻且呈两行两列排布的四个基色光子像素组A围设形成的区域上,如此有利于提高发光器件的像素开口率。
在一些实施例中,如图3所示,每一像素单元11可以包括一个第一基色光子像素111、一个第二基色光子像素112、一个第三基色光子像素113和一个补偿光子像素114,也即上述由相邻且呈两行两列排布的四个基色光子像素组A围设的区域上并非均设置有补偿光子像素114。其中,多个像素单元11的补偿光子像素114可以均匀分布于该多个像素单元11之间,以保证发光器件的整体发光均一性。
在另一些实施例中,每一像素单元11可以包括一个第一基色光子像素111、一个第二基色光子像素112、一个第三基色光子像素113和至少两个补偿光子像素114,且该至少两个补偿光子像素114均匀分布于第一基色光子像素111、第二基色光子像素112和第三基色光子像素113构成的整体上呈圆形的基色光子像素组A的周边区域,以保证单个像素单元11的发光均一性。例如,如图4所示,在上述由相邻且呈两行两列排布的四个基色光子像素组A围设的区域上均设置补偿光子像素114,对应每一像素单元11包括四个补偿光子像素114,且该四个补偿光子像素114在上述基色光子像素组A的周边区域上呈四等份分布。依次类推,当每一像素单元11包括两个补偿光子像素114时,该两个补偿光子像素114可以在上述基色光子像素组A的周边区域上呈二等份分布。
值得注意的是,在上述呈阵列排布的多个像素单元11中,由于边缘切割或边缘结构设计,位于首行、首列、末行或末列的像素单元11的补偿光子像素114的数量可以比位于非边缘区域的像素单元11的补偿光子像素114的数量少,也即位于边缘区域的像素单元11的补偿光子像素114可以减少,或者位于边缘区域的像素单元11可以不包括补偿光子像素114。另外,上述单个像素单元11包括至少一个或至少两个补偿光子像素114,是指在单个像素单元11的基色光子像素组A的周边区域上分布有至少一个或至少两个补偿光子像素114,且在实际显示时,同一个补偿光子像素114可能会被多个基色光子像素组A共用。
在上述实施例中,补偿光子像素114的形状可以为菱形、圆形、椭圆形、正方形、矩形或多边形,例如,如图5所示,补偿光子像素114的形状可以为圆形。具体地,补偿光子像素114可以为白色子像素,且该白色子像素可以是由至少一种合成白光所必要颜色的发光材料与另一种必要颜色的发光材料层叠或混合而形成,例如,白色子像素可以是由红绿蓝三种颜色的发光材料层叠而形成。
在一个具体实施例中,发光器件10还包括位于基板上的图案化的像素界定层(图中未示出),该图案化的像素界定层用于界定基板上用于形成像素的像素区域。具体地,像素单元11形成于基板的像素区域上,且上述三种基色光子像素可以包括依次远离基板的阳极(图中未示出)、空穴注入层(图中未示出)、空穴传输层(图中未示出)、发光层(图中未示出)、电子传输层(图中未示出)以及阴极(图中未示出)。
区别于现有技术,本实施例中的发光器件,包括呈阵列排布的多个像素单元,像素单元包括间隔设置的第一基色光子像素、第二基色光子像素和第三基色光子像素,在每一像素单元中,第一基色光子像素、第二基色光子像素和第三基色光子像素组合后呈圆形,且第一基色光子像素、第二基色光子像素和第三基色光子像素的面积不完全相等,如此,不同像素单元之间无需共用子像素,能够避免由于不同像素单元之间共用子像素而造成分辨率偏低、彩边和边缘锯齿化的问题。
请参阅图6,图6是本申请实施例提供的发光器件的制作方法的流程示意图。该发光器件的制作方法包括以下步骤:
S61:提供基板,基板包括呈阵列排布的多个像素区域,像素区域包括间隔设置的第一基色光子像素区域、第二基色光子像素区域和第三基色光子像素区域,在每一像素区域中,第一基色光子像素区域、第二基色光子像素区域和第三基色光子像素区域组合后呈圆形,且第一基色光子像素区域、第二基色光子像素区域和第三基色光子像素区域的面积不完全相等。
其中,基板为带有基底的TFT基板,基底可以为玻璃基底或者硬质的树脂基底,也可以为用于制备柔性显示面板的柔性基底,且柔性基底的材质可以为聚酰亚胺、聚碳酸酯、聚对苯二甲酸乙二醇酯、聚醚砜基板等有机聚合物中的一种。
在本实施例中,第一基色光子像素区域、第二基色光子像素区域和第三基色光子像素区域的面积与其对应的子像素寿命成反比,以减小不同子像素之间的使用寿命差异,进而延长发光器件的寿命。
例如,在一个实施例中,第一基色光子像素区域可以为红光子像素区域,第二基色光子像素区域可以为绿光子像素区域,第三基色光子像素区域可以为蓝光子像素区域。由于红绿蓝有机发光材料的寿命存在差异,且通常蓝色有机发光材料的寿命短于红色有机发光材料的寿命,红色有机发光材料的寿命短于绿色有机发光材料的寿命,也即蓝光子像素的寿命低于红光子像素的寿命,红光子像素的寿命低于绿光子像素的寿命,因此,可以对应设置蓝光子像素区域的面积大于红光子像素区域的面积,红光子像素区域的面积大于绿光子像素区域的面积。
具体地,在S61之后,还可以包括:
在基板上形成图案化的像素界定层,该图案化的像素界定层用于界定基板上用于形成像素的像素区域。
值得注意的是,上述第一基色光子像素区域、第二基色光子像素区域和第三基色光子像素区域组合后呈圆形,是指整体上呈圆形,在一些实施例中,还可以是呈椭圆形,或呈接近圆形的多边形。
S62:在像素区域上形成像素单元,像素单元包括位于第一基色光子像素区域上的第一基色光子像素、位于第二基色光子像素区域上的第二基色光子像素、以及位于第三基色光子像素区域上的第三基色光子像素。
在本实施例中,第一基色光子像素区域、第二基色光子像素区域和第三基色光子像素区域的面积不完全相等,也即第一基色光子像素、第二基色光子像素和第三基色光子像素的面积不完全相等。且第一基色光子像素、第二基色光子像素和第三基色光子像素的面积与其对应的子像素寿命成反比,以减小不同子像素之间的使用寿命差异,进而延长发光器件的寿命。
在本实施例中,第一基色光子像素区域、第二基色光子像素区域和第三基色光子像素区域组合后呈圆形,对应第一基色光子像素、第二基色光子像素和第三基色光子像素组合后也呈圆形,如此,能够避免在实际显示时出现彩边和边缘锯齿化现象,以及改善实际显示时的视觉效果。
在一个实施例中,第一基色光子像素区域、第二基色光子像素区域和第三基色光子像素区域的形状可以均为扇形,也即第一基色光子像素、第二基色光子像素和第三基色光子像素的形状可以均为扇形。其中,三个基色光子像素对应的圆心角之和为360度,且三个基色光子像素对应的圆心角大小与其对应的子像素寿命成反比。例如,第一基色光子像素为红光子像素,其对应的圆心角范围可以为90~120度,第二基色光子像素为绿光子像素,其对应的圆心角范围可以为60~90度,第三基色光子像素为蓝光子像素,其对应的圆心角范围可以为150~180度,如此,以减小红绿蓝三种子像素发光材料之间的寿命差异,进而延长发光器件的寿命。
在一个具体实施例中,S62可以具体包括:
子步骤A:在第一基色光子像素区域上形成第一基色光子像素。
例如,采用具有第一开口的精细金属掩膜版,通过蒸镀或喷墨打印的方式在第一基色光子像素区域上形成第一基色光子像素。
子步骤B:在第二基色光子像素区域上形成第二基色光子像素。
例如,采用具有第二开口的精细金属掩膜版,通过蒸镀或喷墨打印的方式在第二基色光子像素区域上形成第二基色光子像素。
子步骤C:在第三基色光子像素区域上形成第三基色光子像素。
例如,采用具有第三开口的精细金属掩膜版,通过蒸镀或喷墨打印的方式在第三基色光子像素区域上形成第三基色光子像素。
其中,上述第一开口、第二开口和第三开口的大小与上述基板上的第一基色光子像素区域、第二基色光子像素区域和第三基色光子像素区域的面积大小一一对应。
在另一个实施例中,上述像素区域还可以包括至少一个补偿光子像素区域。具体地,在每一像素区域中,上述第一基色光子像素区域、第二基色光子像素区域和第三基色光子像素区域构成一个整体上呈圆形的基色光子像素组区域,上述补偿光子像素区域位于该基色光子像素组区域的周边区域。
具体地,补偿光子像素区域可以位于由相邻且呈两行两列排布的四个基色光子像素组区域围设形成的区域上,如此有利于提高显发光器件的像素开口率。
在另一个具体实施例中,S62可以具体包括:
子步骤a:利用第一掩膜版,在第一基色光子像素区域和补偿光子像素区域上形成第一基色光子像素。
例如,采用具有第一开口和第四开口的精细金属掩膜版,通过蒸镀或喷墨打印的方式在第一基色光子像素区域和补偿光子像素区域上形成第一基色光子像素。
子步骤b:利用第二掩膜版,在第二基色光子像素区域和补偿光子像素区域上形成第二基色光子像素。
例如,采用具有第二开口和第四开口的精细金属掩膜版,通过蒸镀或喷墨打印的方式在第二基色光子像素区域和补偿光子像素区域上形成第二基色光子像素。
子步骤c:利用第三掩膜版,在第三基色光子像素区域和补偿光子像素区域上形成第三基色光子像素。
例如,采用具有第三开口和第四开口的精细金属掩膜版,通过蒸镀或喷墨打印的方式在第三基色光子像素区域和补偿光子像素区域上形成第三基色光子像素。
其中,在补偿光子像素区域上层叠的第一基色光子像素、第二基色光子像素和第三基色光子像素构成上述补偿光子像素,也即每一像素单元包括第一基色光子像素、第二基色光子像素、第三基色光子像素和补偿光子像素。例如,第一基色光子像素是红光子像素,第二基色光子像素是绿光子像素,第三基色光子像素是蓝光子像素,则在补偿光子像素区域上层叠的第一基色光子像素、第二基色光子像素和第三基色光子像素构成的补偿光子像素可以为白色子像素。
如此,补偿光子像素与相邻的基色光子像素组构成像素单元,不仅能提升画面显示的亮度和色彩度,有效节省能耗,延长发光器件的使用寿命,还能够提高发光器件的像素开口率。
在上述实施例中,第一开口、第二开口、第三开口和第四开口的大小与上述基板上的第一基色光子像素区域、第二基色光子像素区域、第三基色光子像素区域和补偿光子像素区域的面积大小一一对应。
区别于现有技术,本实施例中的发光器件的制作方法,像素单元包括间隔设置的第一基色光子像素、第二基色光子像素和第三基色光子像素,在每一像素单元中,第一基色光子像素、第二基色光子像素和第三基色光子像素组合后呈圆形,且第一基色光子像素、第二基色光子像素和第三基色光子像素的面积不完全相等,如此,不同像素单元之间无需共用子像素,能够避免由于不同像素单元之间共用子像素而造成分辨率偏低、彩边和边缘锯齿化的问题。
