Description

显示面板及其显示方法、 显示装置 技术领域
本发明属于显示技术领域，具体涉及显示面板及其显示方法、 显示装置。 背景技术
在常规的液晶显示装置、 有机发光二极管（OLED)显示装置 中， 每个点 (像素)是由多个子像素通过混光来显示颜色的， 例如每 个像素由红色子像素、 绿色子像素、 蓝色子像素各一个组成 (RGB 模式)。 为了改善视觉效果，人们对于显示装置的分辨率 (单位尺寸 内的像素数)提出了越来越高的要求， 这就要求子像素的尺寸越来 越小， 但由于工艺限制， 子像素尺寸不能无限缩小。 为了在子像 素尺寸一定的情况下改善显示效果， 人们提出了 Pentile模式的显 示装置。 在 Pentile模式的显示装置中， 部分颜色的子像素 (如红色 子像素和蓝色子像素)的数量减半， 同时在显示装置中， 将不同颜 色的子像素虚拟看成处于不同 "层" 中， 并将每个层划分为多个 采样区， 且各层的采样区划分不重合， 之后通过采样区的面积比 计算每个子像素所要显示的内容。 Pentile模式的显示装置中， 部 分子像素是 "共用" 的， 从而在视觉效果上实现了比实际分辨率 更高的分辨率。
但是， 现有的 Pentile模式的显示装置的显示效果仍不理想， 由于其中部分颜色的子像素的数量减半， 故其各种颜色的子像素 不是均勾分布的， 这导致其容易出现锯齿状纹路、 网格状斑点、 细小内容显示不清等问题， 同时由于其采取 "分层分区" 的计算 模式， 故计算每个子像素所要显示的内容需要复杂的运算过程， 运算量大。 发明内容
本发明所要解决的技术问题是， 针对现有的高分辨率显示技 术中存在的显示效果差、 所需的运算量大的问题， 提供一种分辨 率高、 显示效果好、 所需的运算量小的显示面板及其显示方法、 显示装置。
根据本发明的一个方面， 提供一种显示面板， 其包括多个循 环单元， 其中， 每个循环单元由两行子像素组成， 每一行中的子 像素包括红色子像素、 绿色子像素、 蓝色子像素各 1 个， 并且第 一行中的子像素分别相对于第二行中的子像素在行方向上错开半 个子像素的尺寸设置， 且第一行中的子像素的排列方式与第二行 中的子像素的排列方式不同。
以上所述的 "行"是相对于子像素的排列方式而言的，一"行" 中的全部子像素排成一条直线， 而在与 "行" 垂直的 "列" 方向 上， 相邻子像素间 "错开" 半个子像素的尺寸， 即一 "列" 子像 素并非排成直线， 或者说排成一 "列" 的子像素是在行方向上错 开半个子像素的尺寸而分布的。 因此， "行" 、 "列" 与子像素 的形状 (矩形、 圆形、 异形）无关， 与显示面板的放置方式 (竖直放 置、 水平放置、 正置、 倒置等)无关， 与栅线和数据线的排列方式 也无关， 例如， 当显示面板正常放置时， 可能是平行于地面方向 的每排子像素为一 "行" ， 也可能是垂直于地面方向的每排子像 素为一 "行" 。
其中， "第一行中的子像素分别相对于第二行中的子像素错 开半个子像素的尺寸设置" 是指对一循环单元中的两行中的相应 子像素 (比如都是第一个子像素)，它们在列方向上不是排成一条直 线， 而是 "差了" 半个子像素的尺寸， 即一行中的某个子像素的 中心沿列方向垂直投影到其相邻行中后， 对应的不是相邻行中相 应子像素的中心， 而是相邻行中两个子像素之间的连线的中点。
在所述显示面板中， 所述循环单元中的子像素的排列方式为 以下的任意一种： 1 )第一行从左到右依次为： R、 B、 G; 第二行 从左到右依次为： G、 R、 B; 2 ) 第一行从左到右依次为： B、 R、 G; 第二行从左到右依次为： G、 B、 R; 3 ) 第一行从左到右依次 为： B、 G、 R; 第二行从左到右依次为： R、 B、 G; 4 )第一行从 左到右依次为： G、 B、 R; 第二行从左到右依次为： R、 G、 B; 5 ) 第一行从左到右依次为： G、 R、 B; 第二行从左到右依次为： B、 G、 R; 6 ) 第一行从左到右依次为： R、 G、 B; 第二行从左到右 依次为： B、 R、 G; 7 )第一行从左到右依次为： R、 B、 G; 第二 行从左到右依次为： G、 B、 R; 8 ) 第一行从左到右依次为： B、 R、 G; 第二行从左到右依次为： G、 R、 B; 9 ) 第一行从左到右 依次为： B、 G、 R; 第二行从左到右依次为： R、 G、 B; 10 ) 第 一行从左到右依次为： G、 B、 R; 第二行从左到右依次为： R、 B、 G; 11 )第一行从左到右依次为： G、 R、 B; 第二行从左到右依次 为： B、 R、 G; 12 ) 第一行从左到右依次为： R、 G、 B; 第二行 从左到右依次为： B、 G、 R; 13 )第一行从左到右依次为： R、 B、 G; 第二行从左到右依次为： B、 G、 R; 14 )第一行从左到右依次 为： B、 R、 G; 第二行从左到右依次为： R、 G、 B; 15 ) 第一行 从左到右依次为： B、 G、 R; 第二行从左到右依次为： G、 R、 B; 16 )第一行从左到右依次为： G、 B、 R; 第二行从左到右依次为： B、 R、 G; 17 ) 第一行从左到右依次为： G、 R、 B; 第二行从左 到右依次为： R、 B、 G; 18 )第一行从左到右依次为： R、 G、 B; 第二行从左到右依次为： G、 B、 R, 其中， R表示红色子像素， G 表示绿色子像素， B 表示蓝色子像素， 并且第一行中的子像素可 以分别相对于第二行中的子像素在行方向的两个延伸方向中的任 一个延伸方向上错开半个子像素的尺寸而设置。
所述各循环单元排列成矩阵并布满显示面板的显示区。
根据本发明的另一方面， 提供一种显示装置， 其包括上述显 示面板。
本发明的实施例的显示装置和显示面板中， 各种颜色的子像 素的数量相等且均勾排布， 故不会产生锯齿状纹路、 网格状斑点 等不良的问题， 而且， 其中不同行的子像素在行方向上以 "错开 半个子像素尺寸" 的特定方式排列， 再结合特定的 "分区采样" 显示方法， 故其可在视觉效果上实现更高的分辨率， 且颜色过渡 均匀自然， 显示效果好， 同时， 其显示过程中的运算量小， 容易 实现。
根据本发明的又一方面，提供一种上述显示面板的显示方法， 其包括步骤： 根据要显示的画面确定各子像素的初始分量； 以及 根据一子像素及其公用子像素的初始分量确定该子像素的显示分 量， 其中， 一子像素的公用子像素为该子像素周围的多个与其相 同颜色的子像素。
"初始分量" 是指根据要显示的画面， 每个子像素原本应显 示的原始内容 (或者说应显示的 "量" ), 即按照现有的常规显示方 法量其应当显示的内容， 而 "显示分量" 是指经过本发明的方法 进行运算后得出的每个子像素实际应显示的内容。
所述初始分量、 显示分量可以为亮度、 灰度和饱和度中的任 意一种。
在根据一子像素及其公用子像素的初始分量确定该子像素的 显示分量之前， 所述方法还可以包括步骤： 根据要显示的画面确 定各子像素的公用子像素。
所述根据要显示的画面确定各子像素的公用子像素的步骤可 以包括： 判断要显示的画面的内容是过渡均匀且颜色变化不大的 画面、 还是颜色变化较大的画面来确定公用子像素。
所述根据一子像素及其公用子像素的初始分量确定该子像素 的显示分量的步骤可以包括： 将一子像素及其公用子像素的初始 分量分别乘以各自的比例系数， 将所得的值相加后作为该子像素 的显示分量， 其中， 各子像素及其公用子像素的比例系数均为正 数。
一子像素及其公用子像素的比例系数的和可以为 1 , 且该子 像素的比例系数可以大于其公用子像素的比例系数。
所述一子像素的公用子像素可以包括： 分别位于该子像素所 在行的两相邻行中、 并且在行方向上分别位于该子像素两侧且最 靠近该子像素的 4个与其相同颜色的子像素。 所述一子像素的公用子像素可以包括： 分别位于该子像素所 在行的两相邻行中、 并且在行方向上位于该子像素同一侧且最靠 近该子像素的 2个与其相同颜色的子像素。
所述一子像素的公用子像素可以包括： 位于该子像素所在行 的一相邻行中、 并且在行方向上分别位于该子像素两侧且最靠近 该子像素的 2个与其相同颜色的子像素。
本发明的实施例的显示方法中， 不同行的子像素在行方向上 以 "错开半个子像素尺寸" 的特定方式排列， 且每个子像素显示 的内容都是由其本身和周围的多个相同颜色的子像素原本要显示 的内容共同决定的， 即其显示的内容是 "分区采样" 的结果， 故 其可在视觉效果上实现更高的分辨率， 颜色过渡均勾自然， 显示 效果好， 且显示过程中的运算量小， 容易实现。 附图说明

为使本领域技术人员更好地理解本发明的技术方案， 下面结 合附图和具体实施方式对本发明作进一步详细描述。
如图 1所示， 根据本发明的实施例提供一种显示面板， 其包 括多个循环单元 1 ,每个循环单元 1由两行子像素组成，每一行中 的子像素包括红色子像素 21、绿色子像素 22、蓝色子像素 23各 1 个， 第一行中的子像素分别相对于第二行中的子像素在行方向上 错开半个子像素的尺寸而设置， 且第一行中的子像素的排列方式 与第二行中的子像素的排列方式不同。
也就是说， 每个循环单元 1 由 6个子像素组成， 即红色子像 素 21、 绿色子像素 22、 蓝色子像素 23各 2个， 而这 6个子像素 分为两行， 每行为 3个不同的子像素， 即红色子像素 21、 绿色子 像素 22、蓝色子像素 23各 1个， 且两行子像素的具体排列方式不 同， 例如若在一行中从左至右为红色子像素 21、 绿色子像素 22、 蓝色子像素 23, 则在另一行中各子像素必须是不完全相同的另一 种排列， 同时， 这两行子像素不是相互对齐的， 而是第一行子像 素与第二行子像素之间 "差了" 半个子像素的尺寸。 因此， 例如， 当把每个循环单元当成一个 "点" 而排成矩阵并布满显示面板的 显示区后， 在整个显示面板上， 即可得到如图 1 所示的子像素排 列方式。
例如， 循环单元 1中子像素的排列方式可以为图 2所示的 36 种的任意一种， 其中， R表示红色子像素 21 , G表示绿色子像素 22, B表示蓝色子像素 23。 优选的， 循环单元 1中的子像素的排 列方式可以为图 2所示的排列方式中第（1)至第（12)中的任意一种。 经研究发现， 在结合本发明的实施例的显示方法时， 采用这 12种 排列方式的显示面板中的子像素的 "分区 3" (稍后将对其进行描 述） 的形状更规则， 更容易实现， 显示效果更好。
显示面板中的每个子像素能独立发出所需颜色和亮度的光， 通常而言， 子像素是由薄膜晶体管阵列 (有源驱动阵列)控制的， 每 个子像素对应至少一个薄膜晶体管（对有机发光二极管显示装置 而言， 每个子像素对应多个薄膜晶体管）， 并且各薄膜晶体管排成 阵列， 并受栅极线、 数据线的控制。
例如， 该显示面板可以为有机发光二极管显示面板， 其中的 子像素包括发光单元， 而各子像素的发光单元发射的光的颜色对 应于三种子像素的颜色。 也就是说， 本发明的实施例的显示面板 可为有机发光二极管显示面板， 其中每个子像素处具有一个有机 发光二极管 (发光单元），而各有机发光二极管可发出不同颜色的光 (可通过使用不同的有机发光材料实现)，且各有机发光二极管所发 出的光的颜色与其所在子像素的颜色相同， 例如在红色子像素 21 处的有机发光二极管发红光等。
此外， 该显示面板也可为液晶显示面板， 其子像素包括滤光 单元， 透过各子像素滤光单元的光的颜色对应于三种子像素的颜 色。 也就是说， 本发明的实施例的显示面板也可为液晶显示面板， 液晶显示面板本身不发光， 而是通过滤光单元对来自背光源的光 进行滤光以实现彩色显示， 其中， 每个子像素处具有不同颜色的 彩色滤光膜 (滤光单元）， 透过彩色滤光膜的光即可转变为相应颜 色， 其中， 各子像素处彩色滤光膜的颜色与该子像素的颜色相同， 例如在红色子像素 21处的彩色滤光膜为红色等。
当然， 如果采用其他类型的显示面板也是可行的， 只要其能 实现在各子像素处发出相应颜色的光即可， 由于不同类型的显示 面板均可采用已知的结构， 故在此不再详细描述。
根据本发明的实施例还提供一种显示装置， 其包括上述显示 面板。
本发明的实施例的显示装置和显示面板中， 各种颜色的子像 素的数量相等且均勾排布， 故不会产生锯齿状纹路、 网格状斑点 等不良问题， 而且， 其中第一行子像素与第二行子像素在行方向 上以 "错开半个子像素尺寸"的特定方式排列， 再结合特定的 "分 区采样" 显示方法， 故其可在视觉效果上实现更高的分辨率， 且 颜色过渡均勾自然， 显示效果好， 同时， 其显示过程中的运算量 小， 容易实现。 为了在上述显示面板的基础上， 实现更高的分辨率和显示效 果， 根据本发明的实施例还提供一种上述显示面板的显示方法， 其包括以下步骤 S01、 S02、 S03。
步骤 S01、 根据要显示的画面确定各子像素的初始分量。 其中， "初始分量" 是指根据要显示的画面， 按照现有的显 示方法， 显示面板中的每个子像素应当要显示的原始内容 (或者说 应显示的 "量" ；)， 即， 在用本发明的实施例的显示方法进行计算 之前， 其原本应显示的内容。
例如， 初始分量及之后提到的显示分量均为亮度。 也就是说， 可用 "亮度" 表示所要显示的各种颜色的 "量" 。
当然，只要各"分量"能表示所要显示的每种颜色相应的 "量"， 其也可采取其他的度量单位， 例如用 "灰度 (或称灰阶)"作为 "分 量，， 的单位， "灰度" 是在显示领域中对显示亮度的分级指标， 例如对 256灰阶的显示面板， 其最低亮度对应的灰阶为 0, 最高亮 度对应的灰阶为 255, 再比如， 也可以用 "饱和度"作为所述 "分 量" ， "饱和度" 表示彩色偏离同亮度灰色的程度， 即表示其鲜 艳程度。
步骤 S02、 根据要显示的画面确定各子像素的公用子像素。 也就是说， 可根据要显示的画面的具体情况确定各子像素的 公用子像素， 其中， 一子像素的公用子像素为该子像素周围的多 个与其相同颜色的子像素。
本发明的实施例中， 每个子像素要显示的内容通过 "分区采 样" 的方式确定， 具体地， 将不同颜色的子像素看成位于不同的 "层" 中， 每 "层" 只有一种颜色的子像素 (如图 3示出了红色子 像素 21 的 "层" ；)， 之后将该 "层" 分为多个 "分区 3(不同的分 区可部分重叠)" ， 当某子像素要显示时， 其显示内容是由其所在 (只要部分位于 "分区 3" 中即可)的 "分区 3" 中的全部子像素决 定的。 也就是说， 每个子像素显示的内容由其本身和其公用子像 素共同决定。 因此， 公用子像素的选取方式是很重要的。
例如， 一子像素的公用子像素可包括： 分别位于该子像素所 在行的两相邻行中、 并且在行方向上分别位于该子像素两侧且最 靠近该子像素的 4个与其相同颜色的子像素。
也就是说， 如图 4所示， 其中的 "分区 3" 为 "矩形" ， 即 对于图中坐标 (C5, G2)的红色子像素 21, 其公用子像素包括坐标 (S7, Gl)、 （S7, G3)、 （S4, G3)、 （S4, Gl)的 4个红色子像素 21 , 而对于坐标 (S7, G3)的红色子像素 21,其公用子像素包括坐标 (C8, G2)、 （C8, G4)、 （C5, G4)、 （C5, G2)的 4个红色子像素 21。 可 见， 按照这种方式， 某个子像素的 4个公用子像素必然围成一个 "矩形" ， 并把该子像素围在 "矩形" 中。
其中， 本发明的实施例中的坐标系统的意义如下： "Gx" 表 示的是纵坐标， 而 Cx和 Sx表示的是两套横坐标，其中 Sx表示奇 数行 (即 Gl、 G3、 G5行等）中的子像素的横坐标， Cx表示偶数行 (即 G2、 G4、 G5行等）中的子像素的横坐标， 两横坐标互不影响。
此外， 一子像素的公用子像素也可包括： 分别位于该子像素 所在行的两相邻行中、 并且在行方向上位于该子像素同一侧且最 靠近该子像素的 2个与其相同颜色的子像素。
也就是说， 如图 5所示， "分区 3" 也可为 "三角形（例如为 等腰三角形)" ， 即对于图中坐标 (C3, G2)的绿色子像素 22, 其公 用子像素包括坐标 (S5, Gl)、 (S5, G3)的 2个绿色子像素 22, 而 对于坐标 (S5, G3)的绿色子像素 22,其公用子像素则包括坐标 (C6,
G2)、 (C6, G4)的 2个绿色子像素 22。 可见， 按照这种方式， 某 个子像素及其公用子像素必然围成一 "三角形" ， 且其中两公用 子像素的连线平行于列方向。
此外， 一子像素的公用子像素也可包括： 位于该子像素所在 行的一相邻行中、 并且在行方向上分别位于该子像素两侧且最靠 近该子像素的 2个与其相同颜色的子像素。
也就是说， 如图 6所示， "分区 3"也可为另一种不同的 "三 角形" ， 即对于图中坐标 (S5, G1)的绿色子像素 22, 其公用子像 素包括坐标 (C3, G2)、 (C6, G2)的 2个绿色子像素 22, 此时， 某 个子像素及其公用子像素也是围成一 "三角形" ， 区别在于其两 个公用子像素的连线平行于行方向而非列方向。
以上所述的几种公用子像素的选取方式 (或者说 "分区 3" 的 划分方式)比较简单， 所得的 "分区 3" 比较规则、 均匀， 故其显 示效果好且容易实现。
但应当理解， 以上的公用子像素的选取方式并不是对本发明 的限定， 只要是相对靠近某子像素且与其相同颜色的子像素均可 作为其公用子像素。 例如， 对于图 4 中的 "矩形" 分区， 其也可 再 "扩大" 一圏， 从而包括更多的公用子像素， 再如， 对于图 5 和图 6 中的 "三角形" 分区， 某子像素的公用子像素分别均位于 其 "右侧" 或分别均位于其 "下侧" ， 但若某子像素的公用子像 素位于其 "左侧" 或 "上侧" 也是可行的。
另外， 显然的， 对于部分处于显示面板边缘的子像素， 其公 用子像素的取法可能与对于位于显示面板中部的子像素的公用子 像素的取法不同， 但这并不影响本发明的实现。
在步骤 S02中， 具体的， "根据要显示的画面确定各子像素 的公用子像素" 是指对要显示的画面的内容进行分析， 并根据分 析结果确定公用子像素的取法。
例如， 如图 7所示， 当采取上述 "矩形" 的 "分区 3" 时， 若要分别取坐标 (C2, G2)、 （C3 , G2)、 （C4, G2)的红色子像素 21、 绿色子像素 22、 蓝色子像素 23的公用子像素， 则所得的 3个 "分 区 3" 间具有较大的 "重合" 部分， 经研究发现， 这种方式用于过 渡均匀、 颜色变化不大的画面时显示效果更好， 而如图 8所示， 当采取上述 "三角形"的 "分区 3" 时， 若要分别取坐标 (CI , G2)、 (C2, G2)、 （C3 , G2)的蓝色子像素 23、 红色子像素 21、 绿色子像 素 22的公用子像素， 所得的 3个 "分区 3" 间的 "重合" 面积较 小， 经研究发现， 这种方式用于变化较大的画面时显示效果更好。 为此，可对一帧画面进行分析，若其整体上较均勾则采取上述 "矩 形，， 的 "分区 3" , 反之采取 "三角形" 的 "分区 3" 。 或者， 也 可对一帧画面的各部分进行分析， 对其中较均勾的部分 (例如画面 中一个物体的内部)采取上述 "矩形" 的 "分区 3" , 而对其中变 化明显的部分 (例如两个物体的交界处)则采取 "三角形" 的 "分区
3" 。
总之， 根据要显示的画面确定各子像素的公用子像素的具体 方法是多样的， 在此不再详细描述。
当然， 应当理解， 如果不进行本步骤 S02, 而是根据预先设 定的 "分区 3" (或者说公用子像素的选取方式)显示所有画面， 也 是可行的。
S03、根据一子像素及其公用子像素的初始分量确定该子像素 的显示分量。
也就是说， 当某个子像素要进行显示时， 并不是直接显示其 初始分量， 而是对其本身及其公用子像素的多个初始分量进行运 算， 根据多个初始分量最终得出其要实际显示的显示分量。 由于 该子像素最终显示的内容受其公用子像素的影响， 即本步骤相当 于对其 "分区 3"中的全部子像素进行了 "采样"，故也可称为 "分 区采样" 过程。
具体的， 本步骤可包括： 将一子像素及其公用子像素的初始 分量分别乘以各自的比例系数， 将所得的值相加后作为该子像素 的显示分量， 其中， 各子像素及其公用子像素的比例系数均为正 数。
显然， 在进行显示时， 不同子像素（包括该子像素与其公用子 像素，或公用子像素中处于不同位置的子像素）的地位不同，为此， 在进行 "分区采样" 时， 不同子像素的 "权重比例" 也应不同， 而该 "权重比例" 可通过将不同子像素的初始分量分别乘以各自 的比例系数实现。 其中， 各初始分量对应的 "比例系数" 是人为 设定的一个系数， 其可起到调整最终显示内容、 达到最佳显示效 果的作用， 因此， 各 "比例系数" 的取值可根据经验和实际情况 设定、 调整。
例如， 一子像素及其公用子像素的比例系数的和为 1 , 且该 子像素的比例系数大于其公用子像素的比例系数。
也就是说， 一子像素的比例系数及其各公用子像素的比例系 数可以分别是小于 1的正数， 且它们的和为 1 , 并且在这些比例系 数中， 该子像素本身的比例系数大于任意一个公用子像素的比例 系数。 例如， 上述 "矩形" 的 "分区 3" 包括一子像素及其 4个公 用子像素， 则该子像素的比例系数可为 0.6, 其 4个公用子像素的 比例系数可均为 0.1 , 再如， 上述 "三角形" 的 "分区 3" 包括一 子像素及其 2个公用子像素， 则该子像素的比例系数可为 0.7, 其 2个公用子像素的比例系数可均为 0.15。
之所以采用满足以上条件的比例系数， 是因为这样可保证显 示面板的整体亮度不变， 同时， 该子像素本身显然应当比其公用 子像素具有更大的 "权重比例" ， 故其相应的比例系数也应当是 最大的。
当然， 以上比例系数的取法并不是对本发明的限定。 例如， 一子像素及其公用子像素的比例系数的和也可不等于 1 ,再如， 以 上各例子中全部公用子像素的比例系数相等， 但若不同公用子像 素的比例系数不同也是可行的（例如可与其到该子像素的距离有 关)。
此外， 所述显示方法还可以包括步骤 S04: 对全部子像素进 行上述计算， 分别得到其各自的显示分量， 并使各子像素分别显 示各自的显示分量， 从而显示面板显示所需的画面。
可以理解的是， 以上实施方式仅仅是为了说明本发明的原理 而采用的示例性实施方式， 然而本发明并不局限于此。 对于本领 域内的普通技术人员而言， 在不脱离本发明的精神和实质的情况 下， 可以做出各种变型和改进， 这些变型和改进也视为本发明的 保护范围。
