具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行 清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动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。
此后，将以显示面板上的每个像素被划分为三个子像素为例来进行说明，即，每个像素包括第一子像素、第二子像素和第三子像素。但是，本公开实施例不限于此。本领域技术人员应当明白，在进行了适当修改的情况下，也可以将本公开实施例应用于按照其他形式划分的像素布置。
应当明白，虽然可以在这里使用术语第一、第二、第三等描述各种元件、组件、区域、层和/或部分，但是这些元件、组件、区域、层和/或部分不应当为这些术语所限制。这些术语仅被用来将一个元件、组件、区域、层和/或部分与另一个元件、组件、区域、层和/或部分相区分。因而，下面讨论的第一元件、组件、区域、层和/或部分可以被叫作第二元件、组件、区域、层和/或部分，而不会背离本公开的教导。
本公开实施例提供了一种显示面板，包括以阵列布置的多个子像素，其中，沿第一方向布置的子像素按照以下子像素排列中的一个来布置：第一子像素排列，在每两个第二子像素之间插入第一子像素或第三子像素；和第二子像素排列，在每两个第二子像素之间插入第一子像素和第三子像素。
因此，在根据本公开实施例的显示面板中，按照第一子像素排列或第二子像素排列来布置显示面板上的子像素，从而能够提高画面质量。
图1(a)示出第一子像素排列的示意图，并且图1(b)示出第二子像素排列的示意图。
下面，为了描述的简洁，以子像素A来指代第一子像素，以子像素B来指代第二子像素，并且以子像素C来指代第三子像素。
图2(a)至图2(d)示出了第一子像素排列的几个示例。参照图2(a)至图2(d)可以看出，在每两个子像素B之间插入子像素A或C时，可以按以下图案中的一个来进行布置：
(1)依次交替插入A或C，即子像素排列为“BABCBABCBABC……”(如图2(a)中所示)；
(2)依次交替插入C或A，即子像素排列为“BCBABCBABCBA……”(如图2(b)中所示)；
(3)仅插入A，即子像素排列为“BABABABABABA……”(如图2(c)中所示)；
(4)仅插入C，即子像素排列为“BCBCBCBCBCBC……”(如图2(d)中所示)。
对于第一子像素排列，除了单独使用上述四种图案之外，还可以将这四种图案混合使用，例如，当沿一预定方向布置第一子像素排列时，显示面板边界处的图案可以与显示面板中央处的图案不同，以实现更好的显示效果。例如，可以以“BABABABC……BABCBABA”的图案来进行布置。
此外，虽然在这里将第一子像素排列描述为在每两个第二子像素之间插入第一子像素或第三子像素，但是本公开实施例不限于以第二子像素作为起始子像素，本领域技术人员可以明白，还可以以第一子像素或第三子像素作为起始子像素，也就是说，对于第一子像素排列，还可以出现“ABCBABCBABCB……”、“CBABCBABCBAB……”、“ABABABABABAB……”、“CBCBCBCBCBCB……”等排列图案。
这里，为了描述的简洁，将不一一枚举混合后的图案，本领域技术人员可以根据设计需求来灵活布置。
图3示出了第二子像素排列的两个图案单元块。
在第二子像素排列中，子像素可以按照第二子像素、第一子像素和第三子像素的顺序以及第二子像素、第三子像素和第一子像素的顺序中的至少一个来排列。
参照图3，可以按照“BAC”或“BCA”的图案单元块来排列子像素。
例如，根据第二子像素排列，沿同一方向布置的子像素可以是以下图案中的一个：
(1)按照“BAC”图案单元块循环的图案来排列，即“BACBACBAC……；
(2)按照“BAC”图案单元块循环的图案来排列，即“BCABCABCA……”；或
(3)按照“BAC”和“BCA”两个图案单元块任意混合的图案来排列。
在一个实施例中，可以沿第二方向交替布置第一子像素排列和第二子像素排列。
在一个实施例中，可以逐行或列交替布置第一子像素排列和第二子像素 排列。
在另一个实施例中，可以布置第一多行或列第一子像素排列，然后布置第二多行或列第二子像素排列，第一多行或列的数目可以与第二多行或列的数目相同或不同。
但是，本公开实施例不限于此，可以以任意方式来交替布置第一子像素排列和第二子像素排列。
根据本公开实施例，第一方向为行方向和列方向中的一个，并且第二方向为行方向和列方向中的另一个。
各行或各列中第一子像素排列中的图案可以彼此相同，也可以彼此不同。
各行或各列中第二子像素排列中的图案可以彼此相同，也可以彼此不同。
因此，根据本公开实施例，可以根据实际需要和设计需要来非常灵活地布置子像素的排列方式。
在一个实施例中，第一子像素为红色子像素和蓝色子像素中的一个，第二子像素为绿色子像素，并且第三子像素为红色子像素和蓝色子像素中的另一个。
图4示出根据本公开实施例的子像素布置的一个示例。本领域技术人员可以明白，在图4中示出的示例仅仅是在显示面板上布置的一部分子像素。
如图4中所示，第一行子像素采用第一子像素排列中的图案“ABCBABCBABCB……”来排列，第二行子像素采用第二子像素排列中“BAC”和“BCA”两个图案单元块任意混合的图案来排列，第三行子像素仍然采用第一子像素排列中的图案“ABCBABCBABCB……”来排列，第四行子像素采用第一子像素排列中的图案“CBABCBABCBAB……”来排列，第五行子像素采用第二子像素排列中“BAC”和“BCA”两个图案单元块任意混合的图案来排列，第六行子像素仍然采用第一子像素排列中的图案“CBABCBABCBAB……”来排列，依次循环，等等，等等。
因此，在本公开实施例中，通过这样的排列，可以使得沿水平、垂直和45度角布置的同色子像素之间的距离更近，从而使得各方向的线条让人感受更加自然，进而提升了画面质量。
根据本公开实施例，在以上任一种子像素布置的基础上，还可以进一步对各子像素的图像数据进行补偿和映射，以便用两个子像素来显示原来需要 用三个子像素显示的图像数据，从而无需增加实际像素数即可提高等效PPI(Pixels Per Inch，每英寸像素数)。
根据本公开实施例，两个子像素可以组成一个虚拟像素。如图4中所示，每个方格表示一个虚拟像素。可以看出，在图4所示的实施例中，每个虚拟子像素实际是由位于中心的一个完整子像素以及位于左右的两个半个子像素组成的。当然，图4中示出的仅仅是一种子像素排列方式，本领域技术人员应当明白本公开不限于此，显然还可以有很多其他子像素排列方式。
图5示出根据本公开实施例的用于对图像数据进行补偿和映射的电路500的示意性框图。图5中所示的电路可以作为集成电路或分立元件与各像素/子像素一起被布置在显示面板上，或者可以作为外围电路被连接到显示面板。
如图5中所示，电路500可以包括第一补偿单元501、第三补偿单元502、第一映射单元503、第二映射单元505、第三映射单元504和累加单元506。
第一补偿单元501接收子像素A的原始图像数据DA，并利用第一补偿参数Comp1来补偿DA。例如，当子像素A所位于的虚拟像素以子像素A为中心时，Comp1为100％，即子像素A的补偿结果为DA×Comp1＝DA×100％；当子像素A所位于的虚拟像素以子像素B为中心时，Comp1为m1％，即子像素A的补偿结果DA×Comp1＝DA×m1％；并且当子像素A所位于的虚拟像素以子像素C为中心时，Comp1为n1％，即子像素A的补偿结果DA×Comp1＝DA×n1％。这里，m1和n1分别为0至100之间的整数。
第一映射单元503接收第一补偿单元501的补偿结果，并利用第一映射参数Map1来对子像素A的补偿结果DA×Comp1进行映射。例如，当子像素A所位于的虚拟像素以子像素A为中心时，Map1为100％，即子像素A的映射结果DA×Comp1×Map1＝DA×Comp1×100％；并且当子像素A所位于的虚拟像素不以子像素A为中心——即当子像素A同时位于该虚拟像素与另一相邻虚拟像素中——时，Map1＝50％，即子像素A的映射结果DA×Comp1×Map1＝DA×Comp1×50％。
子像素A的输出图像数据dA＝DA×Comp1×Map1。
第三补偿单元502接收子像素C的原始图像数据DC，并利用第三补偿参数Comp3来补偿DC。例如，当子像素C所位于的虚拟像素以子像素C为 中心时，Comp1为100％，即子像素C的补偿结果为DC×Comp3＝DC×100％；当子像素C所位于的虚拟像素以子像素B为中心时，Comp3为m2％，即子像素C的补偿结果DC×Comp3＝DC×m2％；并且当子像素C所位于的虚拟像素以子像素A为中心时，Comp3为n2％，即子像素C的补偿结果DC×Comp3＝DC×n2％。这里，m2和n2分别为0至100之间的整数。这里，m1和n1可以分别与m2和n2相同或不同，并且可以根据所需要的显示效果、实际的子像素排列等因素来调整m1、n1、m2和n2的具体数值。
第三映射单元504接收第三补偿单元502的补偿结果，并利用第三映射参数Map3来对子像素C的补偿结果DC×Comp3进行映射。例如，当子像素C所位于的虚拟像素以子像素C为中心时，Map3为100％，即子像素C的映射结果DC×Comp3×Map3＝DC×Comp3×100％；并且当子像素C所位于的虚拟像素不以子像素C为中心——即当子像素C同时位于该虚拟像素与另一相邻虚拟像素中——时，Map3＝50％，即子像素C的映射结果DC×Comp3×Map3＝DC×Comp3×50％。
子像素C的输出图像数据dC＝DC×Comp2×Map2。
第二映射单元505接收子像素B的原始图像数据DB，并利用第二映射参数Map2来对子像素B的原始图像数据进行映射。例如，当子像素B所位于的虚拟像素以子像素B为中心时，Map2为J％，即子像素B的映射结果DB×Map2＝DB×J％；并且当子像素B所位于的虚拟像素不以子像素B为中心——即当子像素B同时位于该虚拟像素与另一相邻虚拟像素中——时，Map2＝(k+i)％，即子像素B的映射结果DB×Map2＝DB×(k+i)％。这里，k％代表子像素B与原始像素的距离比值，i％代表补偿数值，J、k和i均为0至100之间的整数。
累加单元506接收第一补偿单元501对子像素A的补偿结果DA×Comp1、第三补偿单元502对子像素C的补偿结果DC×Comp3以及第二映射单元505对子像素B的映射结果DB×Map2，并进行叠加，例如简单的相加，作为子像素B的输出图像数据，即子像素B的输出图像数据dB＝DA×Comp1+DC×Comp2+DB×Map3。
应当明白，虽然可以在这里使用术语第一、第二、第三等描述各种元件、组件、区域、层和/或部分，但是这些元件、组件、区域、层和/或部分不应 当为这些术语所限制。这些术语仅被用来将一个元件、组件、区域、层和/或部分与另一个元件、组件、区域、层和/或部分相区分。因而，下面讨论的第一元件、组件、区域、层和/或部分可以被叫作第二元件、组件、区域、层和/或部分，而不会背离本公开的教导。
根据本公开的一个实施例，子像素A为红色子像素和蓝色子像素中的一个，子像素B为绿色子像素，并且子像素C为红色子像素和蓝色子像素中的另一个。
根据本公开的一个实施例，子像素A、子像素B和子像素C的原始图像数据可以是各自通道的彩色数据的亮度数据。
此外，DA×m1％+DC×m2％+DB×J％、DA×n1％+DB×(k+i)％以及DC×n2％+DB×(k+i)％的最大值为子像素B的最大亮度。
此外，在得到子像素A、子像素B和子像素C的输出图像数据dA、dB和dC之后，还可以对dA、dB和dC应用伽马校正，利用伽马查找表(Gamma LUT)来换算得到各子像素所对应的最终灰阶值。
因此，根据本公开实施例，平均用2个子像素即可以显示一个像素的图像数据，因此与用3个子像素来显示一个像素的图像数据的传统方案相比，可以具有150％的等效PPI，从而提高了PPI而无需实际增加子像素数量。
因此，根据本公开实施例，通过上述子像素排列方式，能够提升画面质量，能够在相同的屏幕尺寸下填入更多的显示像素(虚拟像素)。同时，通过利用相应的图像处理算法，能够实现提高PPI的显示效果，并解决了色边的问题。
图6示出根据本公开实施例的、在图4所示的子像素布置的情况下第一补偿单元501的补偿效果示意图，图7示出根据本公开实施例的、在图4所示的子像素布置的情况下第三补偿单元502的补偿效果示意图，图8示出根据本公开实施例的、在图4所示的子像素布置的情况下第一映射单元503的映射效果示意图，图9示出根据本公开实施例的、在图4所示的子像素布置的情况下第三映射单元504的映射效果示意图，并且图10示出根据本公开实施例的、在图4所示的子像素布置的情况下第二映射单元505的映射效果示意图。
图11示出根据本公开实施例的、在图4所示的子像素布置的情况下各子 像素沿列方向的显示情况。
图11中示出5条列直线、即列1至列5，可以看出，对于子像素A(红色子像素)和子像素C(蓝色子像素)，需要利用参数m1、n1、m2和n2来调整邻近子像素B(绿色子像素)的亮度，以最佳化亮度中心(列1、列2和列3)，以避免人眼看到锯齿线条。对于子像素B，只有列4的状况需要利用参数k和i来进行调整，而列5无需调整。
图12示出根据本公开实施例的、在图4所示的子像素布置的情况下各子像素沿行方向的显示情况。
图12中示出4条行直线、即行1至行4。可以看出，通过以上参照图5至图10所描述的过程，对于子像素C(蓝色子像素)，可以利用子像素B(绿色子像素)在距离较远的子像素C中间补上一点亮度，使子像素C的线条看起来较连续(行1和行3)。子像素A的线条原理与子像素C的线条原理类似。
子像素B的线条有行2和行4两种状况，可以透过参数k和i来调整距离较远的子像素B，以提升子像素B的亮度，使得线条变得连续和一致。
图13(a)至图13(d)示出根据本公开实施例的、在图4所示的子像素布置的情况下子像素C沿斜线方向的显示情况，其中，图13(a)示出从左上到右下的子像素C的线条情况1，图13(b)示出从右上到左下的子像素C的线条情况1，图13(c)示出从左上到右下的子像素C的线条情况2，并且图13(d)示出从右上到左下的子像素C的线条情况2。
由于子像素A的情况与子像素C的情况类似，所以这里省略了对子像素A沿斜线方向的显示情况。
图14(a)和图14(b)示出根据本公开实施例的、在图4所示的子像素布置的情况下子像素B沿斜线方向的显示情况，其中，图14(a)示出从左上到右下的子像素B的两种线条情况，图14(b)示出从右上到左下的子像素B的两种线条情况。
通过图13和图14可以看出，根据本公开实施例的子像素布置在行方向、列方向和斜线方向都不会出现缺色的情况，所以可以避免色边的问题。
根据本公开实施例，还提供一种显示装置，包括以上所述的任一种显示面板。
根据本公开实施例，还提供一种子像素排列方法，包括：
在每两个第二子像素之间插入第一子像素或第三子像素；或者
在每两个第二子像素之间插入第一子像素和第三子像素。
因此，在根据本公开实施例的显示面板中，按照第一子像素排列或第二子像素排列来布置显示面板上的子像素，从而能够提高画面质量。
在一个实施例中，在每两个第二子像素之间插入第一子像素和第三子像素包括：按照第二子像素、第一子像素和第三子像素的顺序以及第二子像素、第三子像素和第一子像素的顺序中的至少一个来排列子像素。
在一个实施例中，沿第二方向交替布置第一子像素排列和第二子像素排列。
在一个实施例中，第一方向为行方向和列方向中的一个，并且第二方向为行方向和列方向中的另一个。
在一个实施例中，其中，第二子像素为绿色子像素，第一子像素为红色子像素和蓝色子像素中的一个，并且第三子像素为红色子像素和蓝色子像素中的另一个。
因此，根据本公开实施例，平均用2个子像素即可以显示一个像素的图像数据，因此与用3个子像素来显示一个像素的图像数据的传统方案相比，可以具有150％的等效PPI，从而提高了PPI而无需实际增加子像素数量。
此外，通过利用相应的图像处理算法，能够实现提高PPI的显示效果，并解决了色边的问题。
以上所述，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所述权利要求的保护范围为准。
