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需显示的内容需要复杂的运算过程, 运 算量大。
发明内容

根据本发明的另一个方面, 提供一种显示装置, 其包括上述 的显示面板。
在本发明的实施例的显示面板和显示装置中, 各颜色的子像 素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, 同时, 其中各颜色的子像素以特定方式排列, 由此其 可在视觉效果上能实现更高的分辨率, 且其显示过程中的运算量 小, 另外, 由于其中包括补偿子像素, 故其可实现更好的显示效
果。
根据本发明的又一个方面, 提供一种上述显示面板的显示方 法, 其包括步骤: 使各子像素位置显示所需的红、 绿、 蓝颜色分 量, 该步骤包括使一子像素位置附近的多个相同颜色的彩色子像 素进行显示, 以通过各相同颜色的彩色子像素的平均作用使该子 像素位置显示所需的颜色分量; 以及对各子像素位置进行显示补 偿, 该步骤包括用一子像素位置附近的多个补偿子像素对该子像 素位置进行显示补偿。
在所述显示方法中, 当一子像素位置要显示与该位置的子像 素颜色相同的颜色分量时, 其附近的多个相同颜色的彩色子像素 包括: 该子像素位置的彩色子像素、 以及该子像素位置周围的多 个该颜色的彩色子像素。 当一子像素位置要显示与该位置的子像 素颜色不同的颜色分量时, 其附近的多个相同颜色的彩色子像素 包括: 该子像素位置周围的多个所需颜色的彩色子像素。

在本发明的实施例的显示方法中, 每个子像素位置都能显示 全部颜色分量 (如红色子像素位置处通过其附近的蓝色子像素可 显示出蓝色分量)并被进行补偿, 即每个子像素位置都能显示完整 内容, 相当于一个像素, 因此其视觉效果上的分辨率大幅提高, 同时, 其中每个子像素位置显示的内容均是其附近的多个子像素 的平均结果, 故其显示颜色均匀、 柔和, 显示效果好, 另外, 其 中以每个子像素位置为单位进行显示, 并相应地计算其附近的子 像素所要显示的内容, 因此其不必进行 "分层分区" 的复杂计算, 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的显示面板包括多个子像 素阵列 1 , 每个子像素阵列 1由排成 2行 4列的 8个子像素组成, 且在每个子像素阵列 1 中, 同一行中的 4个子像素分别为 3个彩 色子像素和 1个补偿子像素 X, 上述的 3个彩色子像素分别为红 色子像素1、 绿色子像素 G、 蓝色子像素 B, 以及同一列中的两个 子像素的颜色不同。 也就是说, 每个子像素阵列 1 中的 8个子像 素包括红色子像素 R、绿色子像素 G、 蓝色子像素 B、 补偿子像素 X各两个, 且每行中的 4个子像素的颜色互不相同, 每列中的 2 个子像素的颜色也不同, 这样, 在整个显示面板的行方向上和列 方向上,均不会有相同颜色的子像素相邻 (指靠在一起无间隔)地排 布。
可见, 本实施例的显示面板包括 4种子像素, 即红、 绿、 蓝 3种用于显示所需颜色分量的彩色子像素、以及用于对显示进行补 偿的补偿子像素 X。 与常规显示面板不同的是, 本实施例的显示 面板并非以 4个子像素组成 1个像素单元, 而是以 8个子像素组
成 1个子像素阵列 1 ,再以多个子像素阵列 1排列形成矩阵, 最终 形成子像素阵列。 也就是说, 将每个子像素阵列 1(包括 8个子像 素)看成一个 "点" , 再将这种 "点" 排成矩阵。
例如, 多个子像素阵列 1作为重复单元布满整个显示面板, 即, 多个子像素阵列 1逐行重复排列、 且逐列重复排列。
本实施例的显示面板中, 各颜色的子像素数量相等且均匀排 布, 故不会产生锯齿状纹路、 网格状斑点等不良问题, 同时, 其 中各颜色的子像素以特定方式排列, 由此其可在视觉效果上实现 更高的分辨率, 且其显示过程中的运算量小, 另外, 由于其中包 括补偿子像素 X, 故其可实现更好的显示效果。
例如, 子像素阵列 1中的子像素排列方式为如图 2所示的 11 种中的任意一种。 经研究发现, 以上的 11种排列可取得较好的显 示效果。
例如, 补偿子像素 X为白色子像素、 黄色子像素、 青色子像 素中的任意一种。 以上类型的子像素均可起到显示补偿的作用, 其中白色子像素可用于调整显示面板的亮度, 黄色子像素可用于 改善显示面板的色域, 青色子像素可对蓝色进行补偿、 增加色域、 改善显示效果。 当然, 补偿子像素 X也可为可见光范围内的其他 任意颜色, 只要能起到调整显示效果的作用即可。
例如, 在显示面板中, 在任意位置处的排成 2行 2列的 4个 子像素分别为红色子像素 R、绿色子像素 G、蓝色子像素 B、 补偿 子像素 X。
也就是说,如图 3所示,任意位置的 4个排成方形的子像素(图 中各虚线方框内的子像素)的种类均不同, 在满足这种规律的显示 面板中, 在斜向上也没有相同种类的子像素相邻, 从而可达到更 好的显示效果。 可替代地, 若如图 5 所示, 在部分排成方形的 4 个子像素中有相同种类的子像素 (如图中虚线框中的 2个红色子像 素 R), 也可实现本发明。
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
个子像素对应于至少一个薄膜晶体管 (对有机发光二极管显示装 置而言, 每个子像素对应于多个薄膜晶体管), 并且各薄膜晶体管 排成阵列, 并受栅极线、 数据线的控制。
在一些实施例中,该显示面板可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 3种彩色子像素和 1种补偿子像素 X的颜色。
也就是说, 本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 机发光二极管可发出不同颜色光 (可通过使用不同的有机发光层 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 R处的有机发光二极管发红光等。
在另一些实施例中, 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 3 种彩色子像素和 1种补偿子像素 X的颜色。
也就是说, 本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, 而是对来自背光源的光进行滤光以实现显 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 R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。
本发明的实施例还提供一种显示装置, 其包括上述的显示面 板。
此外,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: 使各子像素位置显示所需的红、 绿、 蓝颜色分 量, 该步骤包括使一子像素位置附近的多个相同颜色的彩色子像 素进行显示以通过各相同颜色的彩色子像素的平均作用使该子像 素位置显示所需的颜色分量; 以及对各子像素位置进行显示补偿,
该步骤包括用一子像素位置附近的多个补偿子像素 X对该子像素 位置进行显示补偿。
其中,以上两个步骤表示的是显示过程中要进行的两种操作, 二者分别用于显示三种彩色颜色的分量和进行显示补偿, 因此这 两个步骤在时间顺序上并无必然的先后关系。
可见, 本实施例的显示方法中, 每个子像素所在的位置(而非 每个子像素)均能显示需要的全部颜色(即同时显示红、绿、蓝 3种 颜色分量), 且每个子像素位置的每种颜色分量均由其附近的多个 相应颜色的彩色子像素共同显示, 通过各彩色子像素的平均作用 使每个子像素位置显示所需要的颜色分量, 同时, 本实施例中还 用补偿子像素 X对各子像素位置进行显示补偿,以改善显示效果, 且每个子像素位置均是由其附近的多个补偿子像素 X补偿的。
在本实施例的显示方法中, 1 : 每个子像素位置都能显示全部 颜色分量 (如红色子像素 R位置处通过其附近的蓝色子像素 B可显 示出蓝色分量), 即每个子像素位置都能显示完整内容, 也就是说 每个子像素位置都相当于一个 "像素" , 这样其视觉效果上的分 辨率大幅提高; 2: 每个子像素位置都被进行显示补偿, 故可通过 补偿子像素 X达到良好的显示效果; 3: 每个子像素位置显示 (补 偿)的内容 (补偿)均是其附近的多个子像素的平均结果, 因此其显 示的颜色均匀、 柔和, 显示效果好; 4: 本实施例的显示方法中以 每个子像素位置为基准进行显示, 并相应地计算其附近的各子像 素所要显示的内容, 因此其可直接计算每个子像素所要显示的内 容, 而不必进行 "分层分区" 等复杂计算, 运算量小, 容易实现。
在本实施例的显示方法中, 例如, 当一子像素位置要显示与 该位置的子像素颜色相同的颜色分量 (如红色子像素 R位置要显示 红色分量)时, 其附近的多个相同颜色的彩色子像素包括: 该子像 素位置的彩色子像素 (即该红色子像素 R)、以及该子像素位置周围 的多个该颜色的彩色子像素 (红色子像素 R)。
另外, 当一子像素位置要显示与该位置的子像素颜色不同的 颜色分量 (如红色子像素 R 的位置要显示绿色分量)时, 其附近的
多个相同颜色的彩色子像素包括: 该子像素位置周围的多个所需 颜色的彩色子像素 (绿色子像素 G)。 也就是说, 此时 "附近的彩色 子像素"不包括该位置的子像素(因其颜色不同)。 而由于补偿子像 素 X的颜色必然与红、 绿、 蓝颜色分量不同, 故其所在的位置必 定属于以上 "颜色不同" 的情况。
其中, 根据需求不同, 对 "附近的彩色子像素" 的取法是多 样的。
例如, 如图 4所示, 当一子像素位置要显示与该位置的子像 素颜色相同的颜色分量时, 其周围的多个该颜色的彩色子像素包 括: 分别位于该子像素位置所在行的两相邻行中、 并且在行方向 上分别位于该子像素位置两侧的 4个最靠近该子像素位置的该颜 色的彩色子像素。
也就是说, 如图 4所示, 当一子像素(图中画圏的红色子像素 R)位置要显示与该位置的子像素颜色相同的颜色分量时, 除了用 该位置的子像素进行显示外, 还用该位置周围的多个该颜色的彩 色子像素进行显示, 而 "周围的彩色子像素" 包括 4个该颜色的 彩色子像素(图中画框的 4个红色子像素 R),这 4个彩色子像素分 别位于该子像素位置的上下两相邻行中, 每行 2个, 且在行方向 上,这 4个彩色子像素分别位于该子像素位置左右两侧 (每侧 2个), 并且均在行方向上最靠近该子像素位置(当然左右两侧的距离可 能不同)。可见,满足上述条件的 4个彩色子像素必然排成一个 "矩 形" , 且该子像素位置位于矩形内。
例如, 当一子像素位置要显示与该位置的子像素颜色不同的 颜色分量时,其周围的多个所需颜色的彩色子像素则可包括以下 2 种不同情况中的任意一种。
第一种情况, 如图 5所示, 该子像素位置周围的多个所需颜 色的彩色子像素包括: 位于该子像素位置所在行的两相邻行中、 并且与该子像素位置同列的两个所需颜色的彩色子像素。
也就是说, 如图 5所示, 当一子像素位置要显示与该位置的 子像素颜色不同的颜色分量时 (如图中画圏的红色子像素 R位置要
显示绿色分量时), 其 "周围的彩色子像素" 可包括位于该子像素 位置相邻的上下方的两个所需颜色的彩色子像素(图中画框的绿 色子像素 G)。
第二种情况, 如图 6所示, 该子像素位置周围的多个所需颜 色的彩色子像素也可包括: 与该子像素位置同行且相邻的 1 个所 需颜色的彩色子像素; 以及位于该子像素位置所在行的两相邻行 中且在行方向上与该子像素位置最靠近的 2个所需颜色的彩色子 像素。
也就是说, 如图 6所示, 当一子像素位置要显示与该位置的 子像素颜色不同的颜色分量时 (如图中画圏的补偿子像素 X位置要 显示红色分量时), 其 "周围的彩色子像素" 也可包括与该子像素 位置同行且相邻的一个彩色子像素(图中位于画圏补偿子像素 X左 侧的画框的红色子像素 R)、 以及分别位于该子像素位置所在行的 相邻的上下两行中、 并且在行方向上与该子像素位置最接近的两 个彩色子像素(图中位于画圏补偿子像素 X右侧的 2个画框红色子 像素 R)。 可见, 在满足上述条件时, 上述 3个 "周围的彩色子像 素,, 必然组成一 "等腰三角形" , 该等腰三角形的底边平行于列 方向, 而该子像素位置位于该三角形中。
按照以上的对 "周围的彩色子像素" 的取法, 可保证所取的 彩色子像素均较靠近该子像素位置, 且数量不会太多, 既可达到 良好的显示效果, 又可避免显示时的运算量过大。
应当理解的是, 上述两种情况的 "周围的彩色子像素" 在图 4的子像素阵列 1的排列方式中也具有相似的特征。 而且,在由图 2中所示的各个子像素阵列重复排列的显示面板中,上述的 "周围 的彩色子像素" 也具有相似的特征, 在此不再重复。
在本实施例的显示方法中, 例如, 在对补偿子像素 X的位置 进行显示补偿时, 其附近的多个补偿子像素 X包括: 该子像素位 置的补偿子像素 X、 以及该子像素位置周围的多个补偿子像素 X。
另外, 在对彩色子像素的位置进行显示补偿时, 其附近的多 个补偿子像素 X包括: 该子像素位置周围的多个补偿子像素 X。
也就是说, 与显示红、 绿、 蓝颜色分量时类似, 在进行显示 补偿时, 依照补偿位置的子像素种类的不同, 其附近的多个补偿 子像素 X的取法也不同,可以包括该位置的子像素(当该子像素就 是补偿子像素 X 时), 也可不包括该位置的子像素(当该子像素是 彩色子像素时)。
同样, 与显示红、 绿、 蓝颜色分量时类似, 在进行显示补偿 时, 对 "周围的补偿子像素 X" 的取法也是多样的。
如图 7所示, 在对补偿子像素 X(图中画圏的补偿子像素 X) 位置进行显示补偿时, 其周围的多个补偿子像素 X包括: 分别位 于该子像素位置所在行的两相邻行中、 并且在行方向上分别位于 该子像素位置两侧的最靠近该子像素位置的 4个补偿子像素 X(图 中画框的 4个补偿子像素 X), 即 "周围的补偿子像素 X" 也可组 成 "矩形" 。
当对彩色子像素(图中画圏的蓝色子像素 B)的位置进行显示 补偿时, 其周围的多个补偿子像素 X可如图 8所示, 包括: 位于 该子像素位置所在行的两相邻行中、并且与该子像素位置同列的 2 个补偿子像素 X(图中画框的补偿子像素 X), 即 "周围的补偿子像 素 X" 也可为该子像素位置相邻的上下方的两个补偿子像素 X。
或者, 也可如图 9所示, 在对彩色子像素(图中画圏的绿色子 像素 G)位置进行显示补偿时, 其周围的多个补偿子像素 X也可包 括: 与该子像素位置同行且相邻的 1个补偿子像素 X、 以及位于 该子像素位置所在行的两相邻行中且在行方向上与该子像素位置 最靠近的 2个补偿子像素 X(图中画框的补偿子像素 X), 即 "周围 的补偿子像素 X" 也可组成 "等腰三角形" 。
以上的对 "周围的补偿子像素 X" 的取法既可达到较好的显 示效果, 又不会使运算量大幅增加。
应当理解, 本实施例中每个子像素位置的内容是由多个子像 素共同显示 (补偿)的, 相应的, 每个子像素也不仅用于一个位置的 显示, 而是用于多个子像素位置的显示。 例如, 如图 3 所示, 对 图中画框的红色子像素 R而言, 当其周围的多个子像素(图中画圏
的各子像素)位置要显示红色分量时, 该红色子像素 R均可能要参 与其中。 因此, 对任何一个子像素, 其要显示的内容也是根据其 所对应的多个子像素位置所要显示的内容共同决定的。
应当理解, 以上的对 "周围的彩色 (补偿)子像素"的取法并不 是对本实施例的限制, 例如, 如图 10所示, 对图中画圏的蓝色子 像素 B的位置而言, 当其要显示蓝色分量时, 其 "周围的彩色子 像素" 也可包括图中的 8个画框的蓝色子像素 B, 这些蓝色子像 素 B中的 4个组成一 "四边形" , 该四边形内的全部蓝色子像素 B 均为 "周围的彩色子像素" 。 总之, 只要是相对靠近某子像素 位置的彩色 (补偿)子像素, 均可为其 "周围的彩色 (补偿)子像素"。
应当理解, 以上对 "周围的彩色 (补偿)子像素" 的取法是可根 据具体显示内容随时变化的。 例如, 在不同帧画面中, 同一个子 像素位置显示同样颜色时所用的 "周围的彩色子像素" 可不同(如 在第一帧画面中用 2个彩色子像素, 第二帧则用 3个), 同样, 在 一帧画面中, 对于不同的子像素位置, 其 "周围的彩色 (补偿)子像 素,, 的取法也可不同。
应当理解, 在确定 "周围的彩色 (补偿)子像素" 时, 对于靠近 显示面板边缘的子像素位置, 其 "周围的彩色 (补偿)子像素" 的取 法可能不同。 例如, 对显示面板最上侧的一行子像素位置, 因其 上方不存在其他子像素, 故可只用其下方的子像素作为其 "周围 的彩色 (补偿)子像素" 。
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。
