背景技术
在液晶显示装置与有机发光二极管显示装置等平板显示装置中均包括多个阵列式排布的像素，每个像素通常包括红、绿、蓝三种颜色的子像素，每个子像素均受控于一条栅极线(Gate line)与一条数据线(Source line)，栅极线用于控制子像素的开启和关闭，数据线通过向子像素施加不同的数据电压信号，使子像素显示不同的灰阶，从而实现全彩画面的显示。参见图1A，其为传统RGB三基色面板架构示意图。该RGB三基色面板分辨率为1080×1920，每个像素11包括RGB三个子像素，Source驱动单元负责向面板提供数据信号。
随着人们节能环保意识的增强以及手机轻薄化的趋势的发展，节能和电池体积轻薄化的需求越来越被手机品牌制造商以及终端消费者所看重，节能变成手机的重大卖点，RGBW四基色显示技术增加白像素以提高面板的穿透率,使用子像素共享算法在解析度不变的前提下减少面板1/3的像素数目以降低超高解析度的生产良率风险，同时降低背光功耗40％，又可提高图像对比度的效果。参见图1B，其为传统RGBW四基色面板架构示意图。该RGBW四基色面板分辨率为1080×1920，每个像素12包括RG两个子像素或BW两个子像素，Source驱动单元负责向面板提供数据信号。
现有RGBW四基色面板多采用2to8De-mux(解复用器)驱动架构，如图2所示，其为现有RGBW四基色面板2to8De-mux驱动示意图。该架构相较于简单的1to4De-mux驱动架构在常见的列反转条件下具有降低功耗的优点。图2中上半部分显示了源极驱动芯片(D-IC)，下半部分显示了面板(Panel)，子像素W1，R2，B2和G1的数据信号通过运算放大器AMP1输入面板，子像素W2，R1，B1和G2的数据信号通过运算放大器AMP2输入面板，现有2to8De-mux驱动结构以两条数据线共计驱动8个子像素为基本单元。随着面板制程工艺的进步，制程工艺逐渐由非晶硅(a-si)转变为低温多晶硅(LTPS)，LTPS具有更高的迁移率，因此为更多数量的复用驱动方案提供了技术保障。

附图说明
下面结合附图，通过对本发明的具体实施方式详细描述，将使本发明的技术方案及其他有益效果显而易见。
附图中，
图1A为传统RGB三基色面板架构示意图；
图1B为传统RGBW四基色面板架构示意图；
图2为现有RGBW四基色面板2to8De-mux驱动示意图；
图3为本发明RGBW四基色面板驱动架构第一较佳实施例的示意图；
图4为本发明RGBW四基色面板驱动架构第二较佳实施例的示意图；
图5为本发明RGBW四基色面板驱动架构第三较佳实施例的示意图；
图6为本发明RGBW四基色面板驱动架构第四较佳实施例的示意图。
具体实施方式
参见图3，其为本发明RGBW四基色面板驱动架构第一较佳实施例的示意图。RGBW四基色面板上的子像素呈阵列排布，对于连接同一扫描线n的连续排列的十二个子像素R1，G1，B1，W1，R2，G2，B2，W2，R3，G3，B3，W3，所述十二个子像素由红色子像素R，绿色子像素G，蓝色子像素B和白色子像素W四个子像素按照R，G，B，W特定顺序排列并且 重复该特定顺序排列三次形成，相邻的两条数据线n和数据线n+1分别连接并驱动所述十二个子像素中奇数列和偶数列上的子像素，数据线n驱动奇数列，数据线n+1驱动偶数列，数据线n和数据线n+1上的信号极性相反，数据线n为正，数据线n+1为负。扫描线n的相邻行n-1，n+1和间隔行n+2中的特定顺序都是R，G，B，W。
本发明针对已有的RGBW四基色面板2to8De-mux驱动架构，提出一种新型的驱动结构，即本发明提出一种新型RGBW四基色面板2to12De-mux驱动架构。本发明的RGBW四基色面板2to12De-mux驱动架构是以两条数据线(Source line)驱动12个子像素(sub-pixel)为基本单元，相较于现有的2to8De-mux驱动架构是以两条Source line驱动8个子像素为基本单元，故在解析度不变的条件下就能够进一步的减少数据线的数量(以FHD(全高清)为例，原数据线条数为1080*2/4＝540，现变为1080*2/6＝360，即降为原来的2/3)，从而减少数据线及DAC(数模转换)模块在Driver IC(驱动芯片)中占用的面积，即可以使IC尺寸减小，从而达到Driver IC成本降低的目的。同时由于数据线OP(运算放大器)数量及DAC转换模块的减少也可以达到降低功耗的目的(相较原来，Source IC只需驱动2/3的数据线OP及DAC转换模块)。而且相较于原有2to8De-mux驱动架构的两正两负极性反转方式，本发明的2to12De-mux驱动架构的极性反转方式为真正的列反转方式，因此具有更小的闪烁(flicker)值。LTPS具有更高的迁移率，可以为本发明所提出的驱动方案提供技术保障。
本发明实现了：
(1)减少DAC及Source OP模块的功耗，从而降低RGBW四基色面板功耗；
(2)减少Source line数量及DAC面积，从而做到Driver IC成本降低；
(3)真正的列反转驱动方式，有利于改善闪烁。
本发明还给出了几种R/G/B/W子像素排列不同的2to12De-mux驱动架构，故类似的2to12De-mux驱动架构也在本发明的保护范围内。
参见图4，其为本发明RGBW四基色面板驱动架构第二较佳实施例的示意图。扫描线n和相隔行的子像素特定顺序为W，B，G和R，相邻行的子像素特定顺序为R，G，B和W。
参见图5，其为本发明RGBW四基色面板驱动架构第三较佳实施例的示意图。扫描线n和相隔行的子像素特定顺序为W，R，G和B，相邻行的子像素特定顺序为R，G，B和W。
参见图6，其为本发明RGBW四基色面板驱动架构第四较佳实施例的 示意图。扫描线n和相隔行的子像素特定顺序为R，W，G和B，相邻行的子像素特定顺序为R，G，B和W。
综上所述，本发明的RGBW四基色面板驱动架构能够降低面板功耗，降低驱动芯片成本，有利于改善闪烁。
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后附的权利要求的保护范围。
