Description
【技术领域】
本发明涉及液晶显示技术领域,特别是涉及一种用于液晶显示装置的像素阵列。
【背景技术】
液晶显示器(liquidcrystaldisplay,LCD)因其体积小、重量轻、功耗低且显示质量优异而获得了飞速发展。为了使液晶显示器能够用于大屏幕显示并最终代替阴极射线显像管(CRT),视角特性还有待改善。
LCD的视角问题是由液晶的工作原理决定的。液晶分子是棒状的,不同的分子排列方式对应着不同的光学各向异性。入射光和液晶分子的夹角越小,双折射率就越小;反之双折射率就越大。偏离显示屏法线方向以不同角度入射至液晶盒的光线与与液晶分子指向的夹角不同,因此不同视角下,有效光程差也不同。而液晶盒的最佳光程差是按照垂直盒的发线方向设计的,对于斜入射的光线,最小透过率随夹角的增大而增大。对比度就会小将。大视角下画面色偏(colorshift)是目前液晶显示器的主要缺陷。
为了降低色偏(Lowcolorshift)现象,Multi-domainVerticalAlignment(MVA)的色偏改善本质是形成尽量多的畴。如果一高一低不同电压同时控制一个子像素的不同区域,就是8畴改善技术。如果两个等级的电压分别控制相连的两个子像素,就是像素渲染(TwoPixelRendering,TPR)技术。TPR技术具有高穿透率的特点。但是,为了使应用TPR技术的液晶面板画质更加细腻,像素充电更加饱满,对液晶面板的像素排列以及驱动像素电压的反转方式提出了特殊要求。
因此,需要提出一种用于液晶显示装置的像素阵列,以克服上述问题。
【发明内容】
本发明的目的在于提供一种用于液晶显示装置的像素阵列。
为实现上述目的,本发明提供一种用于液晶显示装置的像素阵列,所述液晶显示装置包括多条扫描线以及多条数据线,所述像素阵列包含以及多个像素。
所述多个像素分别连接至所述多条数据线,所述多个像素排列为多对像素行,每一对像素行包括两条像素行。所述多条数据线的第N条数据线连接至所述多对像素行的第M对像素行在所述第N条数据线的第一侧或第二侧的所述像素,当M为奇数时,所述第N条数据线连接至所述第M对像素行在所述第N条数据线的所述第一侧的所述像素,当M为偶数时,所述第N条数据线连接至所述第M对像素行在所述第N条数据线的所述第二侧的所述像素,N以及M为正整数。
在一优选实施例中,所述两条像素行的每一条像素行包括多个像素组,每一所述像素组包括八个像素。所述八个像素包括第一像素,接收第一脉冲信号,第二像素,接收第二脉冲信号,第三像素,接收所述第一脉冲信号,第四像素,接收所述第二脉冲信号,第五像素,接收所述第二脉冲信号,第六像素,接收所述第一脉冲信号,第七像素,接收所述第二脉冲信号,第八像素,接收所述第一脉冲信号。

多个像素,分别连接至所述多条数据线,所述多个像素排列为多对像素行,每一对像素行包括两条像素行,所述两条像素行的每一条像素行包括多个像素组。所述两条像素行的每一条像素行包括多个像素组。每一所述多个像素组包括八个像素。所述八个像素包括第一像素,接收第一脉冲信号,第二像素,接收第二脉冲信号,第三像素,接收所述第一脉冲信号,第四像素,接收所述第二脉冲信号,第五像素,接收所述第二脉冲信号,第六像素,接收所述第一脉冲信号,第七像素,接收所述第二脉冲信号,第八像素,接收所述第一脉冲信号。所述多条数据线的第N条数据线连接至所述多对像素行的第M对像素行在所述第N条数据线的第一侧或第二侧的所述像素,当M为奇数时,所述第N条数据线连接至所述第M对像素行在所述第N条数据线的所述第一侧的所述像素,当M为偶数时,所述第N条数据线连接至所述第M对像素行在所述第N条数据线的所述第二侧的所述像素,N以及M为正整数。

【附图说明】
图1,绘示本发明的的一种像素阵列的架构图;
图2,绘示根据图1的像素阵列的显示示意图。
【具体实施方式】
以下各实施例的说明是参考附加的图式,用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语,例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等,仅是参考附加图式的方向。因此,使用的方向用语是用以说明及理解本发明,而非用以限制本发明。
图1,绘示本发明的的一种像素阵列100的架构图。本发明提供一种液晶面板,包括一用于液晶显示装置的像素阵列100,所述液晶显示装置包括多条扫描线以及多条数据线120(包含D1、D2、D3…DN),所述像素阵列100包含多个像素101。所述多个像素101分别连接至所述多条数据线120。所述多个像素101排列为多对像素行130(K1-K2…),每一对像素行130(以K1为例)包括两条像素行110(包含L1、L2)。每一所述多条像素行110包括多个像素组112,每一所述多个像素组112包括八个像素。
所述八个像素包括由左至右分别为:第一像素R,接收第一脉冲信号(由数据线D1传送),第二像素G,接收第二脉冲信号(由数据线D2传送),第三像素B,接收所述第一脉冲信号(由数据线D3传送),第四像素W,接收所述第二脉冲信号,第五像素R,接收所述第二脉冲信号,第六像素G,接收所述第一脉冲信号,第七像素B,接收所述第二脉冲信号,第八像素W,接收所述第一脉冲信号。如同标示,在本优选实施例中,所述第一像素R以及所述第五像素R是红色像素、所述第二像素G以及所述第六像素G是绿色像素、所述第三像素B以及所述第七像素B是蓝色像素以及所述第四像素W以及所述第八像素W是白色像素。
优选地,所述第一脉冲信号以及所述第二脉冲信号是反相的。也就是说每一所述多个像素组112中的八个所述像素由左而右所接受的脉冲信号为“+-+--+-+”,这种方式是一种RGBW液晶面板采用的“1G1D2dotcrossedpixel”驱动方式。
所述多条数据线120的第N条数据线DN连接至所述多对像素行130的第M对像素行在所述第N条数据线DN的第一侧或第二侧的所述像素101,当M为奇数时,所述第N条数据线DN连接至所述第M对像素行在所述第N条数据线DN的所述第一侧的所述像素101,当M为偶数时,所述第N条数据线DN连接至所述第M对像素行在所述第N条数据线DN的第二侧的所述像素101,N以及M为正整数。
举例而言,当N等于1时,所述第1条数据线D1连接至其右侧的第一对像素行K1的所述像素行L1、L2的像素101,但是因为其左侧没有像素,故所述第1条数据线D1不连接至第二对像素行K2的所述像素行L3、L4的任何像素;当N大于或等于2时(以N等于3为例),所述第3条数据线D3连接至其右侧的所述第一对像素行K1的所述像素行L1、L2的像素101,然而所述第3条数据线D3连接至其左侧的所述第二对像素行K2的所述像素行L3、L4的像素101。
图2,绘示根据图1的像素阵列100的显示示意图。通过互为反相的所述第一脉冲信号以及所述第二脉冲信号,让相邻的像素的明暗状态互为相反(一个亮的像素的上下左右四个像素均为暗的)。因为亮暗像素交替排布,在同一行的同颜色且点亮的像素既有正极性驱动又有负极性驱动,同一列的同颜色且点亮的像素亦既有正极性驱动又有负极性驱动。所述具有RGBW四色像素的液晶面板之画质更加细腻,像素充电更加饱满。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
