技术领域

背景技术
随着显示技术的不断发展，人们对于显示装置的分辨率的要求也越来越高。由于具有显示质量高等优点，高分辨率显示装置的应用范围也越来越广。通常，可通过减小像素的尺寸和减小像素间的间距来提高显示装置的分辨率。然而，像素的尺寸和像素间的间距的减少对制作工艺的精度要求也越来越高，从而导致显示装置的制作工艺的难度和制作成本的增加。
另一方面，子像素渲染(Sup-Pixel Rendering，SPR)技术可以利用人眼对不同色彩子像素的分辨率的差异，改变常规的红、绿、蓝三色子像素简单定义一个像素的模式，通过不同的像素间共享某些位置分辨率不敏感颜色的子像素，用相对较少的子像素数，模拟实现相同的像素分辨率表现能力，从而降低制作工艺的难度和制作成本。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公 开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。
图1A中示出了一种显示基板。如图1A所示，该显示基板包括像素排列结构，该像素排列结构为典型的pentile排列方式，一个最小重复单元包括两个绿色子像素0111，一个红色子像素0112和一个蓝色子像素0113，该像素排列均匀分布，易实现高PPI(Pixel Per Inch)显示。每一行中，最小重复单元沿着第一方向X排列，在同一个最小重复单元以及不同的最小重复单元之间的相邻的子像素之间设置有隔垫物010。隔垫物010沿着第二方向Y延伸。第一方向X垂直于第二方向Y。
图1B示出了一种显示基板的剖视示意图，可为沿着图1A中AB向的剖视图。如图1B所示，绿色子像素0111、红色子像素0112、蓝色子像素0113和隔垫物010设置在衬底基板101上。当以一定角度观察显示基板，隔垫物对每个子像素发光亮度影响程度不同，导致出现视角色偏。例如，沿着第一方向X，在不同的角度观看显示基板时，隔垫物010阻挡部分子像素的光进入人眼，从而形成不同视角下的色偏。即，从图1B左侧和右侧观看同一画面时，有视角色偏。
图1C中示出了在一定视角下观看显示装置的示意图。图1C以在显示装置右侧观看为例。因隔垫物010阻挡部分子像素的光，当从左侧观看显示装置时，同一画面的色彩与在右侧观看时不同。
图2A示出了根据本公开至少一实施例提供的一种显示基板。该显示基板包括：第一子像素111、第二子像素112和第一隔垫物0101。第一子像素 111的中心C1和第二子像素112的中心C2的连线为中心连线CL1，中心连线CL1与第一方向X不垂直，第一方向X为行方向或列方向至少之一。
第一隔垫物0101设置在第一子像素111和第二子像素112之间，且第一隔垫物0101在第一子像素111和第二子像素112之间的延伸方向与第一方向X不垂直。
例如，第一隔垫物0101在第一子像素111和第二子像素112之间延伸，且第一隔垫物0101的延伸方向E01与第一方向X不垂直。本公开的实施例中，以第一方向X为行方向为例进行说明。第一隔垫物0101的延伸方向E01与第一方向和第二方向均不同。
本公开至少一实施例提供的一种显示基板，对隔垫物的排布方式进行了调整，第一隔垫物0101的延伸方向E01与第一方向X不垂直的情况下，可减少第一隔垫物对于第一子像素111的遮挡，进而可减小在不同视角下观看画面时的视角色偏。
如图2A所示，根据本公开一个或多个实施例提供的显示基板，为了减小第一隔垫物0101对于第一子像素111的遮挡，第一隔垫物0101的延伸方向E01与第一方向X具有夹角θ1，例如，该夹角θ1范围为40°-50°或130°-140°。进一步例如，该夹角θ1为45°或135°，此情况下，第一隔垫物0101对于第一子像素111的遮挡最小，可较大程度上改善视角色偏。
如图2A所示，根据本公开一个或多个实施例提供的显示基板，中心连线CL1与第一方向X不平行。
如图2A所示，根据本公开一个或多个实施例提供的显示基板，第二子像素112被包括在第一像素组011中，第一子像素111被包括在第二像素组012中。第一像素组011还包括第一子像素111、第三子像素113和第四子像素114，第二像素组012还包括第二子像素112、第三子像素113和第四子像素114。在第一像素组011和第一像素组011中，第二子像素112的中心C2和第三子像素113的中心C3的连线为第一线段LS1；第一子像素111和第四子像素114位于第二子像素112和第三子像素113之间且分设于第一线段LS1的两侧。第一像素组011和第二像素组012在列方向上相邻，在行方向上错位。例如，第一像素组011和第二像素组012均可被称作像素组01。
如图2A所示，根据本公开一个或多个实施例提供的显示基板，在第一 像素组011和第二像素组012中，第一子像素111的中心C1和第四子像素114的中心C4的连线为第二线段LS2；第二线段LS2与第一线段LS1的长度之比小于或等于3/4。从而，当第一子像素111和第四子像素114为同一颜色子像素时，可使得同一像素组01中的第一子像素111和第四子像素114的发光层图形应用掩膜版的同一开口蒸镀形成。
根据本公开一个或多个实施例提供的显示基板，第一隔垫物0101可设置在相邻像素组的第一子像素111和第二子像素112之间，和/或者，设置在相邻像素组的第一子像素111和第四子像素114之间。
如图2A所示，根据本公开一个或多个实施例提供的显示基板，还包括第二隔垫物0102，第二隔垫物0102位于相邻像素组01之间，第二隔垫物0102设置在不同像素组01的第四子像素114和第二子像素112之间，或者设置在不同像素组的第四子像素114和第三子像素112之间；第二隔垫物0102在第四子像素114和第二子像素115之间或者在第四子像素114和第三子像素113之间的延伸方向与第一方向X不垂直。
例如，第二隔垫物0102在不同像素组01的第四子像素114和第二子像素112之间延伸，或者在不同像素组01的第四子像素114和第三子像素113之间延伸。第二隔垫物0102的延伸方向E02与第一方向X不垂直。例如，第二隔垫物0102的延伸方向E02与第一方向和第二方向均不同。
例如，显示基板包括位于奇数行的多个第一像素组011和位于偶数行的多个第二像素组012。显示基板还包括第二隔垫物0102，第二隔垫物0102在各第一像素组011和各第二像素组012至少之一中的第四子像素114和在列方向上与其相邻的第二子像素112和第三子像素113至少之一之间延伸。第二隔垫物0102的延伸方向E02与第一方向X不垂直。
例如，为了减小第二隔垫物0102对于第四子像素114的遮挡，第二隔垫物0102的延伸方向E02与第一方向X具有夹角θ2，例如，该夹角θ2范围为40°-50°或130°-140°。进一步例如，该夹角θ2为45°或135°，此情况下，第二隔垫物对于第四子像素114的遮挡最小，可以进一步减少对人眼敏感像素的遮挡，可较大程度上改善视角色偏。
如图2A所示，隔垫物可为长条形，其延伸方向与第一方向和第二方向均不同，隔垫物包括第一隔垫物0101和第二隔垫物0102。例如，隔垫物的 形状为隔垫物在衬底基板上的正投影的形状。相似的，子像素的形状为子像素在衬底基板上的正投影的形状。
如图2A所示，第二像素组012中的第四子像素114的中心和与该第四子像素114相邻的第一像素组011中的第三子像素113或第四子像素114的中心的连线为中心连线CL2，中心连线CL2与第一方向X不垂直。
根据本公开一个或多个实施例提供的显示基板，第一子像素111和第四子像素114至少之一为人眼敏感颜色子像素。例如，第二子像素112和第三子像素113可为人眼不敏感颜色的子像素。本公开的实施例中，通过减小第一隔垫物和/或第二隔垫物对于敏感颜色子像素的遮挡，从而可减小不同视角下的色偏。例如，第一隔垫物和/或第二隔垫物可位于敏感颜色子像素和不敏感颜色的子像素之间。
如图2A所示，根据本公开一个或多个实施例提供的显示基板，位于第二子像素112或者第四子像素114周围的第一隔垫物0101和第二隔垫物0102组成隔垫物对01012，隔垫物对01012中的第一隔垫物0101和第二隔垫物0102位于第二子像素112或者第三子像素113的同一侧。图2A中以隔垫物对01012位于第二子像素112的同一侧为例进行说明。隔垫物对01012位于非敏感颜色子像素周围，从而可降低隔垫物对01012对于显示色彩的影响，减少视角色偏。
对于AMOLED显示基板，隔垫物有两个作用。一个作用在于支撑发光层图形蒸镀用的掩模版，另一个作用在于封装时支撑盖板。
如图2A所示，根据本公开一个或多个实施例提供的显示基板，为了减少显示基板中的隔垫物的数量，以减少不同视角下的色偏，在第一像素组011和第二像素组012至少之一中(在同一像素组01中)，第一子像素111、第二子像素112、第三子像素113和第四子像素114之间不设置隔垫物。例如，该情况下，可在像素组01之间设置隔垫物对。例如，可在每个像素组01的周围形成三个隔垫物对，进而利于在发光层制作时对于掩膜版的支撑。
图2B示出了根据本公开至少一实施例提供的一种显示基板。该显示基板中，隔垫物对01012中的第一隔垫物0101和第二隔垫物0102位于第三子像素113的同一侧。
图2C示出了根据本公开至少一实施例提供的一种显示基板。该显示基 板包括两种类型的隔垫物对01012。一种类型的隔垫物对01012位于第一像素组011中的第三子像素113的同一侧(例如，左侧)。另一种类型的隔垫物对01012位于第二像素组012中的第二子像素112的同一侧(例如，右侧)。
图2D示出了根据本公开至少一实施例提供的一种显示基板。该显示基板包括第一隔垫物0101和第三隔垫物0103。第三隔垫物0103可设置在不同像素组01的两个非敏感颜色之间。例如，设置在第二子像素112和第三子像素113之间。
为了便于描述像素排列结构，以下去掉显示基板中的隔垫物，对像素排列结构进行描述。本公开实施例中的第一隔垫物0101、第二隔垫物0102、第三隔垫物0103等可设置在如下描述的像素排列结构中。
如图2E所示，本公开至少一实施例提供一种显示基板，该像素排列结构包括多个像素组01。每个像素组01包括第一子像素111、第二子像素112、第三子像素113和第四子像素114。第二子像素112的中心C2和第三子像素113的中心C3的连线为第一线段LS1；第一子像素111和第四子像素114位于第二子像素112和第三子像素113之间且分设于第一线段LS1的两侧。例如，第一子像素111的中心C1和第四子像素114的中心C4的连线为第二线段LS2。第二线段LS2的长度小于第一线段LS1的长度。例如，为了获得较好的像素密排效果，第二线段LS2与第一线段LS1的长度之比小于或等于3/4。
根据本公开至少一实施例提供的显示基板，在显示基板的像素排列结构中，缩小了同一像素组中的第一子像素和第四子像素之间的距离，一方面，可使得像素排列更紧密，降低混色风险、改善彩边，改善视觉颗粒感。另一方面，可拉大子像素之间的间距，以利于制作。或者，也可以兼顾像素排列紧密程度和子像素之间的间距，在二者之间寻求一个平衡，使得像素排列相对紧密且一定程度上拉大子像素之间的间距(像素定义层间距)，以利于兼得降低混色风险、改善彩边，改善视觉颗粒感的效果以及拉大子像素之间的间距的效果。例如，本公开的实施例中给出的各子像素的形状可由像素定义层定义，但不限于此。例如，附图中的各子像素为实际发光区域。各子像素的具体形状可根据制备工艺进行设置。例如，该实际发光区域可由电极、发光层、像素定义层至少之一的形状来确定。
例如，当该种像素排列结构应用于OLED显示基板，第一子像素和第四子像素为相同颜色时，还可以使得同一像素组中的第一子像素和第四子像素的发光层图形应用掩膜版的同一开口蒸镀形成。
例如，第一子像素111和第四子像素114可为人眼敏感颜色的子像素，例如可为绿色子像素、黄色子像素、白色子像素等。例如，相比于第二子像素112和第三子像素113，第一子像素111和第四子像素114的面积相对较小。例如，第一子像素111的面积小于第二子像素112，和/或，第一子像素111的面积小于第三子像素113的面积。类似的，第四子像素114可参照上述对于第一子像素111面积的描述。即，第四子像素114的面积小于第二子像素112，和/或，第四子像素114的面积小于第三子像素113的面积。
根据本公开至少一实施例提供的显示基板，其中的像素排列结构可通过调节视觉位置敏感颜色子像素的间距，改善敏感颜色子像素的分布均匀性，从而可提高该像素排列结构视觉上的分辨率，提升显示质量。
第二子像素112和第三子像素113可为人眼不敏感颜色的子像素。例如，第二子像素112和第三子像素113之一为红色子像素，另一个为蓝色子像素，但不限于此。本公开的实施例中，以第二子像素112为红色子像素，第三子像素113为蓝色子像素为例进行说明。需要说明的是，当像素排列结构采用红绿蓝(RGB)模式时，上述的人眼敏感颜色为可绿色。
如图2E所示，第一线段LS1可以沿第一方向X延伸，第二线段LS2可以沿第二方向Y延伸。例如，第一方向X垂直于第二方向Y。例如，每个像素组01中，第一子像素111和第四子像素114以第一方向X为对称轴进行排列，以使得像素结构排布更均匀。例如，第一子像素111相对第二子像素112和第三子像素113均匀排列，保持一致，以使得像素结构排布更均匀。
如图2E所示，根据本公开一个或多个实施例提供的显示基板，其中的像素排列结构中，第二线段LS2垂直于第一线段LS1。从而，可使得像素排列更均匀。例如，第二线段LS2位于第一线段LS1的中垂线上，此时，各个颜色的子像素在第一方向X上的宽度可均相同，但不限于此。从而，可使得像素结构分布更均匀，画面显示质量更高，改善较低PPI下的显示颗粒感问题。
如图2E所示，为了方便描述，给出了多个正方形的虚线框，每个虚线 框的长度为1/2L，四个虚线框可形成边长为L的正方形。图2E中的深色矩形虚线框内为一个像素组01。该像素组01可为该像素排列结构的最小重复单元。例如，像素排列结构可通过最小重复单元的平移复制而得。例如，最小重复单元内不包括可平移重复以进行排列以形成像素结构的子单元。例如，如图2所示，深色矩形虚线框的长度为2L，宽度为L。
如图2E所示，第一线段SL1与第二线段SL2垂直，且互相垂直平分。第一线段SL1垂直平分第二线段SL2。第二线段SL2也垂直平分第一线段SL1。例如，像素组01中，第一子像素111、第二子像素112、第四子像素114和第三子像素113的中心的连线围成的最大区域呈菱形，第一线段SL1和第二线段SL2分别为该菱形的对角线。
如图2E所示，在像素组01中，第一子像素111的中心C1和第四子像素114的中心C4之间的距离可大于或等于1/2L，例如，该距离的范围可从1/2L至L。例如，第一子像素111和第四子像素可采用相同颜色的子像素。第一子像素111和第四子像素采用相同颜色的子像素，例如均为第一子像素111时，该距离的设置还可避免因相邻的第一子像素距离较近而导致的相邻的两个第一子像素难以分辨，被人眼视觉上合二为一的情况，从而可避免因此产生的颗粒感。由此，该像素排列结构可改善第一子像素的分布均匀性，从而可提高视觉上的分辨率，并且还可提升显示质量。
如图2E所示，第三子像素113的中心C3和第二子像素112的中心C2之间的距离可为4/3L。为了使得第二线段LS2与第一线段LS1的长度之比小于或等于3/4，可在工艺允许的条件下，拉大同一像素组内第三子像素113和第二子像素112之间的距离，和/或者，减小第一子像素111和第四子像素114之间的距离。
如图2E所示，根据本公开一个或多个实施例提供的显示基板，为了获得紧密排列的像素结构，第二线段LS2与第一线段LS1的长度之比可大于或等于3/8。
请继续参考图2A，如图2A所示，第一隔垫物0101和第二隔垫物0102中至少一个与第一子像素111和第三子像素113的中心连线无交叠。例如，第一隔垫物0101和第二隔垫物0102中至少一个与蓝色子像素和绿色子像素中心连线无交叠。
例如，为了减小不同视角的色偏，第一隔垫物0101在沿第一方向的直线上的正投影与第二子像素112和第三子像素113至少之一在沿第一方向的直线上的正投影无交叠或部分交叠。
例如，第一隔垫物0101和第二隔垫物0102的数量之和与子像素数量的比值为0.3-1。例如，子像素包括第一子像素111、第二子像素112、第三子像素113和第四子像素114。例如，在同一像素组中，第一隔垫物0101和第二隔垫物0102的数量之和与子像素数量的比值为0.3-1。
上述对隔垫物的位置设计以防止角度色偏的问题进行了描述。然而，本公开的实施例还提供另一种针对隔垫物的解决方案。例如，可以使用透明隔垫物防止角度色偏。透明隔垫物的位置不限于上述位置。例如，透明隔垫物可以采用一种高透光率甚至全透明并且符合其他可替代要求的材料来代替透光率差的聚酰亚胺材料。此时，无论从哪个角度观察屏幕，由于选用材料高透光率，并且对不同波长的光透过无选择性，所以无论是红光还是蓝光，均可正常出射，不受隔垫物的遮挡。该正常出光与观察角度无关，从而在一定程度上改善了屏幕白画面下的角度色偏以及左右视角不对称问题。
隔垫物可选用的替代材料可以是有机硅。有机硅薄膜具有优异的耐热性，低温柔韧性，高介电常数，以及绝缘性能等。另外，有机硅薄膜，例如以二甲基硅氧烷(PDMS)为原料的高分子聚合物薄膜具有无色和光学全透明性，其毫米级厚度时仍可达到很高甚至百分之九十以上的光透过率，可使得隔垫物在可见光范围内有良好透明度。以一种有机硅材料N-(三甲氧基硅丙基)-4-叠氮-2，3，5，6-四氟苯甲酰胺(PFPA-silane)为例说明，该有机硅材料具有高透光率(接近80％)，并且不同波长下对光的透过率相差不大。
另外，隔垫物的材料也可以是经过改性的，无色透明的新型聚酰亚胺材料。由于聚酰亚胺本身的诸多优异特性，加之经过改性的对可见光全波段的高透光率，可以作为透明隔垫物的材料。例如，可以采用聚酰亚胺与二氧化硅PI/SiO 2复合薄膜。改性之后的PI/SiO 2复合薄膜经过优化后，透光率相比于纯聚酰亚胺大大提高，而且在可见光范围内对波长几乎无选择性，不同波长下的透光率几乎一致。而高透光率及光透过对波长无选择性这两点特性都有利于角度色偏的改善。
图3A中给出了去除了图2E中给出的虚线的像素排列结构。本公开的实 施例中给出的虚线，中心等是为了便于描述给出的虚拟线，虚拟中心。例如，中心可为重心，对边的垂直平分线的交点等，但不限于此。
图3B示出了根据本公开一个或多个实施例提供的显示基板。同一像素组01中，第一子像素111和第四子像素114采用同一种颜色。例如，均为第一子像素111。由于同色子像素没有混色问题，同一像素组01中的第一子像素111和第四子像素114的发光层图形可采用掩膜版的同一开口进行蒸镀，从而，可利于掩膜版的张网，张网压力小，提高张网的质量。
如图3B所示，因同一行的第一子像素111的斜率较低，当属于同一行的第一子像素111共同显示直线时，由于斜率较低(图3B中的密集点虚线)，相邻像素组的第一子像素的波动幅度较小，从而可避免因波动幅度较大而导致的与相邻的行所显示的直线相互咬合而产生的两条直线难以分辨，被人眼视觉上合二为一的情况。由此，该像素排列结构可提高视觉上的分辨率。
图3C示出了根据本公开一个或多个实施例提供的显示基板。如图3C所示，各像素组01中，第一子像素111和第四子像素114为相同颜色的子像素，例如可包括两种类型的像素组，一种类型的像素组中相同颜色的成对子像素为第一子像素(例如，绿色子像素)，另一种类型的像素组中相同颜色的成对子像素为第四子像素(例如，白色子像素或者黄色子像素)。在每个像素组的对角线方向上相邻的像素组中的位于第二子像素和第三子像素之间的成对设置的两个子像素的颜色与该像素组中位于第二子像素和第三子像素之间的成对设置的子像素的颜色不同。
图4示出了根据本公开一个或多个实施例提供的显示基板，如图4所示，第一线段LS1可以沿第一方向X延伸，在第一方向X上相邻的两个像素组01中的相邻的第二子像素112和第三子像素113之间的中心连线LS3的长度D1小于第一线段LS1的长度，以使得像素可以紧密排列。图4中以第一线段LS1的长度为4/3L为例进行说明，但并不限于此。例如，第一线段LS1的长度范围可为11/9L-13/9L。
例如，为了使得像素尽可能的紧密排列和工艺条件允许相结合，在第一方向上相邻的两个像素组01中的相邻的第二子像素112的中心和第三子像素113的中心之间的中心连线LS3的长度D1与第一线段LS1的比值小于或等于1/2。图4中以距离D1的长度为2/3L为例进行说明，但并不限于此。例 如，距离D1的长度范围可为5/9L-7/9L。
如图4所示，根据本公开一个或多个实施例提供的显示基板，其中的像素排列结构中，多个像素组01呈阵列排列，包括多行和多列，例如，可包括位于奇数行的多个第一像素组011和位于偶数行的多个第二像素组012。例如，偶数行的像素组和奇数行的像素组错位排布。第二线段LS2可以沿第二方向Y延伸。例如，为了实现在列方向上的像素密排，在相邻的奇数行或者在相邻的偶数行中，在第二方向Y上相邻的两个像素组01中的相邻的第一子像素111和第四子像素114的中心连线L14的长度D2大于第二线段LS2的长度。例如，在相邻的奇数行或者在相邻的偶数行中，在第二方向Y上相邻的两个像素组01中的相邻的第一子像素111和第四子像素114的中心连线L14的长度D2与第二线段LS2的长度的比值大于等于1并且小于等于3。
例如，在相邻的奇数行或者在相邻的偶数行中，在第二方向Y上相邻的两个像素组01中的相邻的第一子像素111和第四子像素114的中心连线L14的长度D2大于第二线段LS2的长度。
从而，可形成一个像素组周围密排6个像素组的像素结构。奇数行像素组和偶数行像素组错位排布。例如，可在第一方向X上错位半个像素组在第一方向X上的长度，例如，错位长度为L，但不限于此。例如，在相邻的奇数行或者在相邻的偶数行中，在第二方向Y上相邻的两个像素组01中的相邻的第一子像素111和第四子像素114的中心连线的长度D2与第二线段LS2的长度的比值大于等于1并且小于等于3。
如图4所示，根据本公开一个或多个实施例提供的显示基板，其中的像素排列结构中，每个像素组01的第二线段LS2的延长线穿过在第二方向Y上与该像素组01相邻并且位于同一行的两个像素组01的中心连线LSC的中点C0。每个像素组01的中心为C1，相邻两个像素组01的中心C1的连线为中心连线LSC。例如，像素组01的中心C1可以为第一线段LS1和第二线段LS2的交点。
例如，每个第一像素组011的第二线段LS2的延长线穿过与该第一像素组011相邻并且位于同一行的两个第二像素组012的相邻的第三子像素113和第二子像素112的中心连线LS3的中心C5。例如，中心C5和中心C0可为同一个点。
如图4所示，根据本公开一个或多个实施例提供的显示基板，在相邻的奇数行或者在相邻的偶数行中，在第二方向Y上排列的相邻两个像素组01(相邻两个第一像素组011或相邻两个第二像素组012)中的两个第三子像素113的中心连线LS4和位于该两个第三子像素113之间的像素组01中的第一线段LS1的交点IP1位于该第一线段LS1的中心IP0与第二子像素112的中心C2之间。例如，第一线段LS1的中心IP0可以为该像素组01的中心C1。例如，交点IP1位于第一线段LS1的中心IP0与第二子像素112的中心C2连线的中点。
例如，在相邻奇数行中，位于同一列的相邻第一像素组011的两个第三子像素113的中心连线LS4和与该第三子像素113相邻的第二像素组012的第一线段LS1的交点IP1位于该第二像素组012的第一线段LS1的第一线段LS1和第二线段LS2的交点IP0和第二子像素112的中心C2之间的位置。上述描述中的第三子像素113也可替换为第二子像素112。
例如，在相邻的奇数行或者在相邻的偶数行中，在第二方向Y上排列的相邻两个像素组01(相邻两个第一像素组011或相邻两个第二像素组012)中的两个第二子像素112的中心连线和位于该两个第二子像素112之间的像素组01中的第一线段LS1的交点位于该第一线段LS1的中心IP0与第三子像素113的中心C3之间。例如，该交点位于第一线段LS1的中心IP0与第三子像素113的中心C3连线的中点。
例如，第一隔垫物0101设置在不同行的相邻像素组之间。例如，第二隔垫物0102设置在不同行的相邻像素组之间。
如图4所示，根据本公开一个或多个实施例提供的像素排列结构，同一像素组中，第二子像素112与第一子像素111之间的最近距离为L1，第二子像素112与第四子像素114之间的最近距离为L2，第三子像素113与第一子像素111之间的最近距离为L3，第三子像素113与第四子像素114之间的最近距离为L4，L1＝L2＝L3＝L4。
如图4所示，根据本公开一个或多个实施例提供的像素排列结构，第一子像素111或第四子像素114和在第二方向上与其相邻的且与其不在同一行的像素组中的第二子像素112和第三子像素113的最近距离分别为L5和L6，L5＝L6。
例如，在一个实施例中，L1＝L2＝L3＝L4＝L5＝L6。
例如，有关L1、L2、L3、L4、L5和L6也可参照图7A和7B中有关于最小工艺间距d的标注。各最近距离为两个子像素之间的最小距离。例如，在实际制作时，可使得L1、L2、L3、L4、L5和L6尽量接近于最小工艺间距d。例如，最近距离为两个子像素的外边缘上最近的两个点之间的距离。
如图4所示，根据本公开一个或多个实施例提供的像素排列结构，相邻子像素中，各相对的边大概平行或夹角小于45°，相邻子像素包括第一子像素111、第二子像素112、第三子像素113和第四子像素114中任意相邻的两个。
如图5A所示，根据本公开一个或多个实施例提供的显示基板，其中的像素排列结构中，第一子像素111和第四子像素114均为条形，第一子像素111的延伸方向A1与第四子像素114的延伸方向A2不重合。例如，第一子像素111的延伸方向A1与第四子像素114的延伸方向A2相交或者有夹角。例如，每个像素组中，第一子像素111和第四子像素114以第一方向X为对称轴进行排列，并进行一定角度的倾斜。例如，倾斜角度与第一方向X夹角范围为30°-50°，进一步例如，夹角为45°，但不限于此。例如，第一子像素111的延伸方向A1可为第一子像素111的长轴方向，但不限于此。例如，第四子像素114的延伸方向A2可为第四子像素114的长轴方向，但不限于此。
如图5A所示，根据本公开一个或多个实施例提供的像素排列结构，每个像素组01中，第一子像素111和第四子像素114相对于第一线段LS1对称排列。例如，每个像素组01中，第一子像素111和第四子像素114相对于第二线段LS2不对称排列。
例如，第二子像素112和第三子像素113相对于第二线段LS2对称排列，但不限于此。
例如，本公开的实施例中，条形是指一个方向的长度大于另一个方向的长度，或者，在一个方向上尺寸大于其他方向尺寸即可。条形不限于矩形，可以为其他形状，例如，可以为长条六边形，长椭圆形，梯形或其他形状。本公开的实施例中，各子像素的形状不限于规则形状，也可以为不规则形状。
例如，第一子像素111的延伸方向A1与第四子像素114的延伸方向A2的夹角为70°-100°，进一步的，夹角可为80°-95°，更进一步，夹角可为90° (直角)，从而，可利用形成较大面积的第一子像素111和第四子像素114，以提高出光面积，并利于制作发光层图形的掩膜版制作时的张网。例如，为直角的情况下，可以允许有上下几度的偏差。例如，可以与90°上下偏差5°。
图5B示出了根据本公开一个或多个实施例提供的显示基板，其中的像素排列结构中，第一子像素111的延伸方向A1与第四子像素114的延伸方向A2的夹角为直角，并且，在同一像素组01中，第一子像素111和第四子像素114为相同颜色子像素。
图6示出了根据本公开一个或多个实施例提供的显示基板。如图6所示，第二子像素112和第三子像素113可为菱形或近似菱形的形状。近似菱形例如包括圆角菱形，切角菱形等，但不限于此。菱形或近似菱形的形状的子像素形状更加利于像素密排。例如，可使得第一子像素111能够比较对称的围绕在第三子像素113和第二子像素112的周围，第一子像素111的长边均朝向第二子像素112，短边均朝向第三子像素113，以最大程度保证像素排列的均一。第一子像素111的排列更加均匀，可以一定程度上改善彩边，有利于高PPI的实现，可以尽可能高的提高像素开口率。
各子像素的形状不限于之前所述，子像素的形状可根据需要进行调整。面积最大化是确定子像素形状的主要原则。
为避免混色，不同颜色子像素间距需大于图形化工艺的最小工艺间距d，再考虑某些特殊工艺对称性要求，例如，FMM张网希望开孔图形和分布对称，第一子像素和第四子像素的形状可分别为直角底角的对称五边形(如图2E所示)。可以看到，采用对称形状子像素的相邻像素组间第二、三子像素间距明显地大于其他不同颜色子像素间距(最小工艺间距d)，即，设计上仍存在可利用面积。在FMM张网技术允许或采用其他对对称性不敏感(如CF)工艺情况下，可以采用非对称子像素形状实现子像素面积最大。
图7A和图7B示出了根据本公开一个或多个实施例提供的显示基板中的像素排列结构。如图7A和图7B所示，在允许采用非对称子像素形状的条件下，根据不同的图形化工艺最小工艺间距d，第二子像素112和第三子像素113形状可以为直角梯形或切掉锐角的直角梯形，以使得面积最大化。
如图7A所示，由于第二子像素112和第三子像素113的形状均为直角梯形，相对于第二子像素112和第三子像素113的形状均为六边形(两个直 角底角对称五边形联合形成六边形)的情况，第二子像素112和第三子像素113的锐角部190可进一步提高第二子像素112和第三子像素113的面积，从而进一步提高像素组内的空间利用率。该像素排列结构可提高对像素组内的空间利用率。
如图7B所示，第二子像素112和第三子像素113的形状均为锐角被切角的等腰梯形。从而，在工艺精度一定的情况下，也就是说，第一子像素111分别与第二子像素112和第三子像素113的距离一定的情况下，增加第二子像素112和第三子像素113的面积，从而提高对像素组内的空间的利用率。
根据本公开一个或多个实施例提供的显示基板中的像素排列结构，第二子像素112和第三子像素113的形状包括等腰梯形、六边形、菱形至少之一，第二子像素112包括五边形、矩形、近似矩形至少之一。近似矩形例如包括圆角矩形，但不限于此。
图8示出了根据本公开一个或多个实施例提供的显示基板。如图8所示，在同一行像素组中，第三子像素113和第一子像素111可采用第一驱动线DL1驱动，第二子像素112和第四子像素114可采用第二驱动线DL2驱动。第一驱动线DL1沿E1方向延伸，第二驱动线DL2沿E1方向延伸。例如，E1方向平行于第一方向X。
如图8所示，奇数列像素组中的第一子像素111和第四子像素114可采用第一数据线DT1输入数据信号，位于相邻两条第一数据线DT1之间的第二子像素112和第三子像素113可采用第二数据线DT2输入数据信号。例如，数据信号包括电压和/或电流。第一数据线DT1沿E2方向延伸，第二数据线DT2也沿E2方向延伸，E2方向平行于第二方向Y。
图9示出了一种显示基板的示意图。该显示基板中，各子像素在第一方向X上的宽度不相同。因，各子像素的宽度不相同，在不同视角下观看时也容易产生色偏。
图10示出了本公开一个或多个实施例提供的显示基板的示意图。沿第一方向X，第一子像素111、第二子像素112、第三子像素113和第四子像素114在第一方向X上的宽度相同。从而，可减小在不同视角下观看时的视角色偏。
例如，一个像素单元组包括两个像素单元，例如，第一子像素111和第 二子像素112形成一个像素单元，第三子像素113和第四子像素114形成另一个像素单元。每个像素单元中可以共用与其相邻的第三子像素111或第四子像素114以进行全彩显示。采用子像素共用的方式实现显示。像素单元的划分方式不限于上述描述。此处的像素单元可称为虚拟像素。虚拟像素的划分与驱动方式相关。虚拟像素的具体划分方式可以根据实际的驱动方式确定，本公开对此不作具体限制。
图11示出了本公开一个或多个实施例提供的显示基板的示意图。如图11所示，显示基板包括第三隔垫物0103，第三隔垫物0103位于像素组01中的第一子像素111和第四子像素114之间。例如，第一子像素111和第四子像素114可同为绿色子像素，但不限于此。
侧视角度下，各子像素的发光不受第三隔垫物0103的遮挡，从而在一定程度上改善显示白画面时，左右视角下的色偏不对称现象，提升画质和显示效果。通过设置第三隔垫物0103，在左右方向基本上消除了对各子像素出光遮挡不一致的问题，进而可以在极大程度上消除左右角度色偏不对称的现象，而对于上下方向由于第三隔垫物只对第一子像素和第四子像素有遮挡，即便是由于对第一子像素和第四子像素有遮挡而产生角度色偏，但由于在上下两个方向相同的角度下对第一子像素和第四子像素的遮挡是一致的，因而不存在角度色偏不对称的现象。例如，通过调节第三隔垫物0103的大小和厚度可以调整其对第一子像素111和第四子像素114的遮挡程度，进而调节在上下方向的角度色偏程度。
如图11所示，第三隔垫物0103的延伸方向E03垂直于第一子像素111的中心C1和第四子像素114的中心C4的连线CL0，但不限于此。
如图11所示，第三隔垫物0103在第一方向X上的长度大于第一子像素111和第四子像素114至少之一在第一方向X上的长度。
如图11所示，第一子像素111和第四子像素114的形状均为五边形，五边形包括一组平行的对边以及一条垂直边，垂直边与一组平行的对边垂直。第三隔垫物0103平行于五边形的垂直边。
图12是本公开一实施例提供的显示基板的截面图。如图12所示，该结构包括衬底基板001以及依次位于衬底基板001上的缓冲层002、第一栅极绝缘层003、第二栅极绝缘层004、层间介电层005、平坦化层006以及像素 限定层007。从图12中可以看到，在子像素的下方有一个薄膜晶体管结构，该薄膜晶体管结构包括栅极302、有源层301以及漏电极303。该薄膜晶体管可为像素驱动电路中的一个薄膜晶体管，其与其他部件的连接关系可以根据具体的像素电路布置而设置，这里不再详细示出。此外，在与漏电极303同层的位置处还可以包括信号线304，该信号线304也可以根据不同的像素电路布置而用作特定功能的信号线，例如，数据线或栅线等。从图12可以看到，像素限定层007可以包括限定子像素的开口。子像素的阳极403和第三子像素的发光层503位于像素限定层007的开口中。需要说明的是，显示基板的结构不限于图12所示。
例如，阳极403与发光层503彼此接触，从而在彼此接触的部分能够驱动发光层进行发光，因此，阳极403和发光层503彼此接触的部分为子像素能够发光的有效部分。在这里阳极403用作像素电极，从而能够给不同的子像素施加不同的数据电压。但根据本公开的实施例中，用作子像素的像素电极的电极不限于阳极，也可以将发光二极管的阴极用作像素电极。因此，在本公开的实施例中，子像素的形状可以是指像素电极与发光层彼此接触的部分的形状。例如，对于每个子像素，像素电极的面积可以稍大于发光层的面积，或者也可以是发光层的面积稍大于像素电极的面积，本公开的实施例对此没有特别限定。例如，这里的发光层可以包括电致发光层本身以及位于电致发光层两侧的其他功能层，例如，空穴注入层、空穴传输层、电子注入层以及电子传输层等等。在有些实施例中，像素的形状也可以由像素限定层来定义。例如，对于发光二极管的下电极(例如，阳极)可以设置在像素限定层的下方，像素限定层包括用于限定像素的开口，该开口露出下电极的一部分，当发光层形成在上述像素限定层中的开口中时，发光层与下电极接触，从而在这部分能够驱动发光层进行发光。因此，在这种情况下，像素限定层的开口定义了子像素的形状。
例如，像素电路中包括至少一个晶体管，所述晶体管包括栅极、有源层以及源漏极。在一个示例中，信号线通过贯穿其下方的绝缘层的过孔与相应的晶体管的源极或漏极电连接。在一个示例中，晶体管的有源层由多晶硅层形成，在有源层的沟道区的两侧，多晶硅层被导体化以形成源漏极。例如，所述信号线通过过孔与被导体化而形成的多晶硅源极或漏极电连接。例如， 晶体管为顶栅极晶体管，用于将所述信号线电连接到相应晶体管的源极或漏极的过孔穿过栅极金属层和数据金属层，且与所述栅极金属层和数据金属层的一部分金属图案可以用作过孔电连接的中继连接件，但根据本公开的实施例不限于此。
例如，对于本公开实施例中所描述的各种子像素的形状，均为大致的形状，在形成发光层或各种电极层时，并不能保证子像素的边沿为严格的直线且角为严格的角状。例如，发光层可以通过掩模用蒸镀工艺来形成，因此，其角部可以为圆角形状。在一些情况下，金属刻蚀会有拔模角，因此，在利用蒸镀工艺形成子像素的发光层时，其发光层的一个角可能被去掉。例如，本公开的实施例中，各个子像素的形状均为圆角图形。
例如，如图2A所示，一个像素组中，第一子像素111和第二子像素112为不同颜色的子像素，第一子像素111和第二子像素112形成一个像素P，第三子像素113和第四子像素114为不同颜色的子像素，第三子像素113和第四子像素114形成一个像素P，在显示图像时需要借用周围其他像素的子像素进行彩色显示。例如，第一子像素111和第四子像素114为绿色子像素，第二子像素112为红色子像素，第三子像素113为蓝色子像素。例如，一个红色子像素和一个绿色子像素形成一个像素，一个蓝色子像素和一个绿色子像素形成一个像素。这里的像素P仅包括两种颜色的子像素，在显示图像时需要借用周围其他像素的子像素进行彩色显示。因此，这里的像素P也可以称为虚拟像素。在高分辨率的情况下，绿色子像素对每个像素的被感知的亮度中心位置起着决定性的作用。例如，一个红色子像素和一个绿色子像素形成的像素的亮度中心位于红色子像素和绿色子像素之间且更靠近绿色子像素的位置处，一个蓝色子像素和一个绿色子像素形成的像素的亮度中心位于蓝色子像素和绿色子像素之间且更靠近绿色子像素的位置处。
例如，如图2A所示，第二子像素和第三子像素的形状均为六边形，六边形的三组对边均平行；第一子像素和第四子像素的形状均为五边形，五边形包括一组平行的对边以及一条垂直边，垂直边与一组平行的对边垂直；其中，第一子像素和第四子像素的垂直边相邻设置；第二子像素中一组较长的平行对边、第三子像素中一组长的平行对边、第一子像素中的一组平行的对边以及第四子像素中的一组平行的对边平行。
在对像素排列结构进行设计时，子像素一般会设计为规则的形状，比如，六边形、五边形、梯形或其他形状。在进行设计时，子像素的中心可以是上述规则形状的几何中心。然而，在实际制造工艺中，所形成的子像素的形状一般会与上述设计的规则形状有一定的偏差。例如，上述规则的形状的各个角可能会变成圆角，因此，子像素的形状可以为圆角图形。此外，实际制造的子像素的形状还可能会与设计的形状有其他的变化。例如，设计为六边形的子像素的形状在实际制造中可能变成近似椭圆形。因此，子像素的中心也可能并非制作形成的子像素的不规则形状的严格的几何中心。在本公开的实施例中，子像素的中心可以与子像素的形状的几何中心有一定的偏移量。子像素的中心是指从子像素的几何中心出发到子像素的边缘各点的辐射线段上的特定点所围成的区域内的任一点，该辐射线段上的特定点在距离该几何中心1/3该辐射线段的长度处。该子像素中心的定义适用于规则形状的子像素形状的中心，也适用于不规则形状的子像素的中心。
如上所述，由于各种制造误差，实际制造的子像素形状可能与设计的子像素形状有偏差。因此，在本公开中对于涉及子像素中心的位置以及子像素中心与其他对象的位置之间的关系也可以是有一定的误差的。例如，子像素中心之间的连线或经过子像素中心的线，如果这些线满足对应的其他限定(例如，延伸方向)，这些线只要经过上述的辐射线段的中心围成的区域即可。再例如，子像素的中心位于某条线上，是指这条线穿过上述的辐射线段的中心围成的区域即可。
此外，虽然在附图中的各子像素形状包括严格的由两条线段形成的角，但在一些实施例中，各个子像素的形状可以均为圆角图形。也就是，在上述各种图形形状的基础上，各个子像素的角被倒圆。例如，对于发光层通过掩模进行蒸镀的情况下，发光层位于角落处的部分则可能会自然形成圆角形状。
本公开至少一实施例提供一种显示装置，包括上述任一显示基板。因此，可改善不同视角色偏，提高显示质量。在显示装置采用本公开的实施例给出的像素排布结构的显示面板时，还可进一步提高该显示装置的分辨率，进而可提供一种具有真实的高分辨率的显示装置。另外，由于本公开的实施例给出的像素排列结构可具有较好的对称性，进而，可提高像素分布的均匀性，提高显示装置的显示效果。
例如，在一些示例中，该显示装置可以为智能手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
有以下几点需要说明：
(1)本公开实施例附图中，只涉及到与本公开实施例涉及到的结构，其他结构可参考通常设计。
(2)在不冲突的情况下，本公开同一实施例及不同实施例中的特征可以相互组合。
以上，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以权利要求的保护范围为准。
