Description

像素结构及其驱动方法、 显示面板及显示装置 技术领域
本发明的实施例涉及一种像素结构及其驱动方法、显示面板及显示装置。 背景技术
在平板显示技术中， 薄膜晶体管液晶显示器（TFT-LCD )具有低功耗、 制造成本相对较低和无辐射的特点，因此其在平板显示器市场占据主导地位。 TFT-LCD设有多个子像素组成的像素结构，常规的像素结构上设有交叉排列 的栅线和数据线，栅线和数据线的每个交叉处设有一个子像素（通常红、绿、 蓝三个子像素构成一个可见的像素单元） 。 每个子像素均通过薄膜晶体管与 临近的栅线和数据线相连。 为了减少数据线的数量， 筒化驱动过程， 也有数 据线减半的像素结构。 如图 1所示， 一种数据线 S减半的像素结构中， 数据 线 S数量减半，栅线 G数量加倍， 即一根数据线 S分别与其两侧的两列子像 素 A1-2相连， 且与同一根数据线 S相连的同一行的两个子像素 A1-2分别连 接两根栅线 G, 其中， 构成一个像素单元的各子像素排成一行。 当驱动第一 行栅线 G1时， 设于各数据线 S左侧的子像素 A1-2依次选通（即 Rll、 Bll、 G12、 R13、 B13、 G14 · · · · Rln-1、 Bln-1、 Gin ) , 当驱动第二行栅线 G2时， 设于第一行的数据线 S右侧的子像素 A1-2依次选通（即 Gil、 R12、 B12、 G13、 R14、 B14 · · · · Gln-1、 Rln、 Bin ) , 这样逐行依次扫描， 因此， 同一像素单元中的三个子像素实际是被两根数据线分别驱动的。 如图 2所示， 该像素结构的源极驱动的时序图， 驱动两行栅线 G为一个周期。
采用上述数据线 S减半结构的像素结构， 由于在像素结构的驱动设计中 必须考虑到如图 3所示的正置、 倒置两个驱动传输方向， 所以必须要求在像 素结构中要设有 12的倍数个子像素 A1-2,否则最终的数据线数目会是单数。 由于时序控制器（Tcon )算法， 这导致在倒置传送时将会出现空集合（即没 有用的资料） 。 上述像素结构设计局限， 而且时序复杂。 发明内容 本发明所要解决的技术问题包括， 针对现有的减半的数据线结构的像素 结构设计的局限性和时序复杂的问题， 提供一种结构容易实现、 时序筒单的 像素结构及其驱动方法、 显示面板及显示装置。
解决本发明技术问题所采用的技术方案是一种像素结构， 包括排列成阵 列状的多个子像素， 每个子像素由一个薄膜晶体管驱动； 设于同一行的子像 素由位于其上下的两条栅线驱动； 一条数据线对位于其两侧的两列子像素进 行驱动； 由一条数据线驱动的位于两相邻行中的多个子像素构成一个像素单 元。
本发明实施例的像素结构中每个像素单元包括四个子像素， 故其在光学 角度考虑， 光感效果更好， 而且四个像素构成一个像素单元的排列方式布线 少。
在一个示例中， 所述像素结构采用双栅方式， 所述像素单元包括位于同 一数据线两侧的四个子像素， 所述四个子像素的排布方式是每行和每列各两 个子像素， 每个子像素由一条栅线进行驱动， 同一行的子像素由位于其两侧 的两条栅线进行交叉驱动。
在一个示例中， 所述每个像素单元包括四种不同颜色的子像素。
在一个示例中， 所述四种不同颜色的子像素包括红色子像素、 绿色子像 素、 蓝色子像素和黄色子像素。
在一个示例中， 所述四种不同颜色的子像素包括红色子像素、 绿色子像 素、 蓝色子像素和白色子像素。
本发明的另一个实施例提供了一种显示面板， 包括：
排列成阵列状的多个子像素， 每个子像素由一个薄膜晶体管驱动； 沿所述阵列的行方向延伸的多条栅线； 以及
沿所述阵列的列方向延伸的多条数据线， 其中，
设于同一行的子像素由位于其上下的两条栅线驱动，
一条数据线对位于其两侧的两列子像素进行驱动， 并且
由一条数据线驱动的位于两相邻行中的多个子像素构成一个像素单元。 解决本发明技术问题所采用的技术方案是上述像素结构的驱动方法， 包 括如下步骤：
选通与一像素单元对应的第一条栅线， 通过数据线驱动与第一条栅线相 连的子像素；
选通与该像素单元对应的第二条栅线， 通过数据线驱动与第二条栅线相 连的子像素；
选通与该像素单元对应的第三条栅线， 通过数据线驱动与第三条栅线相 连的子像素；
选通与该像素单元对应的第四条栅线， 通过数据线驱动与第四条栅线相 连的子像素。
本发明实施例根据上述像素结构提供了一种新的驱动方法， 时序筒单， 容易实现。
本发明实施例的技术方案还提供了一种显示装置，其包括上述像素结构。 由于该显示装置包括上述像素结构， 每个像素单元由四个子像素组成， 故其画面感更好。 附图说明

图 4为本发明的实施例 1的数据线减半的像素结构的结构图； 以及 图 5为本发明的实施例 2的数据线减半的像素结构的像素单元的时序图。 具体实施方式
为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本发 明实施例的附图，对本发明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发明的一部分实施例， 而不是全部的实施例。 基于所描 述的本发明的实施例， 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， 都属于本发明保护的范围。
实施例 1 : 本实施例提供一种像素结构， 包括： 排列成阵列状的多个子像素 A1-2, 每个子像素 A1-2由一个薄膜晶体管 A1-1驱动； 设于同一行的子像素 A1-2 由位于其上下的两条栅线 G交叉驱动；一条数据线 S驱动位于其两侧的两列 子像素 A1-2; 由一条数据线 S驱动的位于两相邻行中的多个子像素 A1-2构 成一个像素单元 A。
如图 4所示， 例如， 所述像素结构采用双栅方式（数据线减半的方式）， 所述像素单元 A包括位于同一数据线 S两侧的四个子像素 A1-2, 所述四个 子像素的排布方式是每行和每列各两个子像素 A1-2, 每个子像素 A1-2由一 条栅线 G进行驱动， 同一行的子像素 A1-2由位于其两侧的两条栅线 G进行 交叉驱动。该像素结构由多个像素单元 A构成，一个像素单元 A由四个相邻 带有不同颜色（该颜色可由彩膜产生， 彩膜可位于彩膜基板上， 也可位于像 素结构上）的子像素 A1-2构成，其中四个子像素 A1-2可以为多种不同模式， 例如， 四个子像素 A1-2包括： 红子像素、 绿子像素、 蓝子像素、 黄子像素， 或包括红子像素、 绿子像素、 蓝子像素、 白子像素。
一个像素单元 A的四个子像素 A1-2分别位于一根数据线 S的两侧， 且 每侧设有相邻的两个子像素 Al-2。
也就是说，一个像素单元 A的四个子像素 A1-2例如排列成一个"方块"， 这样显示效果较好， 且比较方便布线。
该像素结构的每一根栅线 G驱动设于该行的一种子像素 A1-2 (比如说 第一根扫描线只驱动设于第一行的红色子像素） ， 且一根数据线 S对应四根 栅线 G, 采用这种结构在布线连接筒单、 筒化了驱动过程。
实施例 2:
本实施例提供一种实施例 1中所述的像素结构的驱动方法， 具体步骤如 下：
选通与一像素单元 A对应的第一条栅线 G1 , 通过数据线 S驱动与第一 条栅线 G1相连的子像素 Al-2(即 Rl l、 R12、 R13 Rln);
选通与该像素单元 A对应的第二条栅线 G2, 通过数据线 S驱动与第二 条栅线 G2相连的子像素 Al-2(即 Gl l、 G12、 G13 Gin);
选通与该像素单元 A对应的第三条栅线 G3 , 通过数据线 S驱动与第三 条栅线 G3相连的子像素 A1-2 (即 Bl l、 B12、 B13 Bin ) ； 选通与该像素单元 A对应的第四条栅线 G4, 通过数据线 S驱动与第四 条栅线 G4相连的子像素 A1-2 (即 Yll、 Y12、 Y13 Yin ) ；
依次选通每根栅线 G。
图 5显示该结构的像素结构的像素单元 A驱动过程的时序图，对比现有 技术像素结构的像素单元 A驱动过程的时序图可以看出，本发明实施例时序 筒单， 容易实现。
实施例 3:
本实施例提供一种显示面板， 该显示面板包括实施例 1中的像素结构。 并且， 该显示面板可以采用实施例 2的驱动方法进行驱动。 由于上文已经对 像素结构及其驱动方法进行了详细描述， 此处不再重复。 另外， 这里的显示 面板包括但不限于液晶显示面板和有机发光显示面板。
实施例 4:
本实施例提供一种显示装置， 该显示装置包括实施例 1中的像素结构或 者包括实施例 3所述的显示面板。 该显示装置可以为： 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。
本实施例的显示装置中具有实施例 1的像素结构， 每个像素单元由四个 子像素组成， 故其画面效果好。
当然， 本实施例的显示装置中还可以包括其他常规结构， 如电源单元、 显示驱动单元等。
以上所述仅是本发明的示范性实施方式， 而非用于限制本发明的保护范 围， 本发明的保护范围由所附的权利要求确定。
