Description
显示面板
本发明涉及平面显示领域, 尤其涉及一种显示面板。 背景技术
液晶显示装置 (LCD, Liquid Crystal Display )具有机身薄、 省电, 无 辐射等众多优点, 得到了广泛的应用。 现有巿场上的液晶显示装置大部分 为背光型液晶显示装置, 其包括壳体、 设于壳体内的液晶显示面板及设于 壳体内的背光模组 (backlight module ) 。 液晶显示面板的工作原理是在两 片平行的玻璃基板当中放置液晶分子, 通过通电与否来控制液晶分子改变 方向, 将背光模组的光线折射出来, 并通过设置于玻璃基板上的像素结构 产生彩色画面。
请参阔图 1 至图 3, 基于薄膜晶体管 (TFT) 的液晶显示面板, 其像 素有两种常见的子像素排列方式: "水平排列" 和 "垂直排列" 。
以仅含红色子像素 R、 绿色子像素 G、 蓝色子像素 B三子像素的薄膜 晶体管的液晶显示面板为例, "子像素水平排列" 对应于 "单扫描线 ( Gate ) 三数据线 (Data ) 驱动" , 筒称为 "1G3D" 模式 (如图 4 所 示) ; 而 "子像素垂直排列" 对应于 "三扫描线 ( Gate ) 单数据线 (Data)驱动" , 简称为 "3G1D" 模式 (如图 5所示) 。
3G1D 面板的驱动方式为 "逐行扫描" , 如图 6 所示: 在显示一帧图 像的时间周期 T 内, 首先第一根扫描线 G(i)被选通, 此时数据线的信号 (电压)都写到第一行子像素 (此处为红色子像素 R) 中, 即第 X列的数 据线 D(x)的电压写到第 X列第一行的红色子像素 R(x,l)中; 接着第二根扫 描线 G(2)被选通, 此时数据线的电压都写到第二行子像素 (此处为绿色子 像素 G) 中, 即第 X列的数据线 D(x)的电压写到第 X列第二行的的绿色子 像素 G(x,l)中; ……; 最后第 3N (N 为垂直方向总像素数)根扫描线 G(3N)被选通, 此时数据线的电压都写到第 3N行子像素 (此处为蓝色子像 素 B ) 中, 即第 X列的数据线 D(x)的电压写到第 X列第 3N行的蓝色子像 素 Β(χ,Ν)中。
当显示单色画面时, 非常容易发生数据线 "重载" , 造成子像素充电 异常, 从.而造成色偏。 以图 7 示例: 面板的数据线相对于共电极 ( Common )每帧反转一次偏压极性, 显示颜色为红色 (255, 0, 0) , 由
外围驱动芯片 (Source IC )给出的数据线电压波形如图 7a所示, 其中 102 段、 104段、 106段分别代表应写入 RGB 子像素的电压, 由于传输延迟 ( RC Delay ) , 实际写入 RGB子像素的电压波形如图 7b所示。 此时, R 子像素充电不足, G子像素被稍许误充电, B 子像素完全不充电, 整个画 面发生色偏(偏黄) 。 发明内容

为更进一步阐述本发明所采取的技术手段及其效果, 以下结合本发明 的优选实施例及其附图进行详 ·细描述. tl
请参阅图 8 , 本发明提供一种显示面板, 包括数个主像素单元, 每一 主像素单元包括横向排列的两个主像素, 每一主像素包括纵向排列的数个 不同颜色的子像素, 所述相邻两主像素的不同颜色的子像素的排布顺序不 同。
在本实施例中, 所述显示面板为 3G1D模式的液晶显示面板, 所述数 个子像素为三个, 其分别为红色子像素 R、 绿色子像素 G 及蓝色子像素 B。 所述两个主像素分别为第一主像素与第二主像素, 所述第一主像素的 子像素排布由上至下依次为红色子像素 R、 绿色子像素 G 及蓝色子像素
B。 所述第二主像素的子像素排布由上至下依次为红色子像素 R、 蓝色子 像素 B及绿色子像素 G。
当显示单色画面时, 例如红色 ( 255 , 0 , 0 ) : 由外围驱动芯片 ( Source IC )写给第一主像素的红色子像素 R、 绿色子像素 G及蓝色子像 素 B 的数据线电压波形如图 9a所示, 实际写入第一主像素的红色子像素 R、 绿色子像素 G 及蓝色子像素 B 的数据线电压波形如图 9b 所示; 由 Source IC写给第二主像素的红色子像素 R、 蓝色子像素 B及绿色子像素 G 的数据线电压波形如图 9c 所示, 实际写入红色子像素 R、 蓝色子像素 B 及绿色子像素 G的数据线电压波形如图 9d所示。
对于第一主像素的红色子像素 R、 绿色子像素 G及蓝色子像素 B: 红 色子像素 R充电不足, 绿色子像素 G被稍许误充电, 蓝色子像素 B完全 不充电, 实际显示效果为 "红色偏黄" (即通常情况) ; 对于第二主像素 的红色子像素 R、 蓝色子像素 B及绿色子像素 G: 红色子像素 R 充电不
足, 蓝色子像素 B被稍许误充电, 绿色子像素 G完全不充电, 实际显示效 果为 "红色偏紫" 。
这样一来, 相邻两个主像素的中和效果为 "红色偏白" , 也就是色别 不变、 饱和度降低。 由于人眼对色别的敏感度高于对饱和度的敏感度, 可 以有效改善 3G D模式的液晶显示面板的色偏问题。
请参阅图 10 , 为本发明第二实施例的像素排布示意图, 在本实施例 中, 所述第一主像素的子像素的排布顺序不变, 所述第二主像素的子像素 排布由上至下依次为绿色子像素 G、 红色子像素 R及蓝色子像素 B, 同样 请参阅图 发明第三实施例的像素排布示意图, 在本实施例 中, 所述第一主像素的子像素的排布顺序不变, 所述第二主像素的子像素 排布由上至下依次为蓝色子像素 Β、 绿色子像素 G及红色子像素 R, 同样 请参阅图 12, 为本发明第四实施例的像素排布示意图, 在本实施例 中, 所述两个主像素分别为第三主像素与第四主像素, 所述第三主像素的 子像素排布由上至下依次为红色子像素 R、 绿色子像素 G、 蓝色子像素 B 及白色子像素 W。 所述第四主像素的子像素排布由上至下依次为白色子像 素 W、 蓝色子像素 B、 绿色子象素 G及红色子像素 R, 同样可以实现上述 技术效果。
综上所述, 本发明显示面板通过将相邻两主像素的不同颜色的子像素 按不同的顺序排布, 使得相邻两个主像素的中和效果为 "红色偏白" , 有效避免由于数据线 "重载" 而造成的色偏现象, 进而有效改善 3G1D模 式的液晶显示面板的色偏问题, 提高显示面板的显示效果好。
以上所述, 对于本领域的普通技术人员来说, 可以根据本发明的技术 方案和技术构思作出其他各种相应的改变和变形, 而所有这些改变和变形 都应属于本发明权利要求的保护范围。
