Description

RGBW显示面板驱动电路结构 技术领域
本发明涉及显示技术领域，尤其涉及一种RGBW显示面板驱动电路结构。
背景技术
液晶显示面板(Liquid Crystal Display，LCD)、及有机发光二极管(Organic Light Emitting Diode，OLED)显示面板均具有多个呈矩阵式排列的像素。传统的像素通常包括红(Red，R)、绿(Green，G)、蓝(Blue，B)三种颜色的子像素，现有技术中所采用的R、G、B彩色滤光片都是吸收型色层，当光线入射时，只有相应颜色的光才能透过，而另外两种颜色的光均被吸收，使得显示面板的透光率较低。由此，出现了在一个像素内形成红、绿、蓝、空白(White，W)四种颜色子像素的显示技术，其中，W子像素不添加色层，通过控制其对应的灰阶来控制该W子像素的透光量，可以提高显示面板的透光率，此类显示面板被称为RGBW显示面板。
请参阅图1，现有的RGBW显示面板在像素设计时通常将同一行左右相邻的两个子像素构成一个正方形的像素结构单元P1’，且任意两个左右相邻的像素结构单元P1’必须包括红色子像素R、绿色子像素G、蓝色子像素B、及空白子像素W这四种颜色的子像素；设i为奇数，针对第i行与第i+1行子像素，任意两个上下相邻的像素结构单元P1’必须包括红色子像素R、绿色子像素G、蓝色子像素B、及空白子像素W这四种颜色的子像素；另外，设a、n均为正整数，第a条数据线D(a)设置在第a列子像素的左侧，第n条扫描线G(n)设置在第n行子像素的上端，第a列第n行的子像素通过与其对应的驱动TFT T电性连接第a条数据线D(a)、及第n条扫描线G(n)，也即每条数据线均通过相应的驱动TFT T来驱动位于其右侧的子像素，这种像素排布设计可以增大像素的开口率，提升面板的亮度。
与传统常规的RGB面板相比，图1所示的RGBW显示面板中的任意一列子像素会存在着不止一种颜色的子像素分布，例如对于第一条数据线D(1)控制的第一列子像素，包含有红色子像素R、绿色子像素G、蓝色子像素B这三种颜色的子像素。
请参阅图2，扫描线按G(1)、G(2)、G(3)……直至G(2n-1)、G(2n)的顺序自上而下逐条开启扫描，其中VGH表示高电位用以控制驱动 TFT T打开，VGL表示低电位用以控制驱动TFT T关闭，在图2所示的驱动顺序下，上述现有的RGBW显示面板在显示纯色画面时，每条数据线内的数据信号输出需要不断地进行变换，属于重载显示，由于阻容延迟(RC delay)的影响，面板很容易出现错充，从而引起色偏，影响面板的显示效果；尤其是在面板测试阶段，RC delay更为严重，而纯色画面属于常检画面，容易造成误判，导致面板良率降低。
结合图1至图4，以上述现有的RGBW显示面板显示纯绿色画面为例，对于第一条数据线D(1)控制下的第一列子像素，当第一条扫描线G(1)内的扫描信号开启时，第一条数据线D(1)内数据信号的电位为高电位以对绿色子像素G进行充电；当第二条扫描线G(2)内的扫描信号开启时，第一条数据线D(1)内数据信号的电位切换到公共(Com)电位；当第三条扫描线G(3)内的扫描信号开启时，第一条数据线D(1)内数据信号的电位又上升到高电位，依次进行下去，整个切换的过程对于驱动IC的负荷太大。如图4所示，由于面板本身存在的RC delay，绿色子像素G下方的红色子像素R、及蓝色子像素B也会出现错充的现象，所以当面板显示纯绿色画面时，会出现泛白的现象。同样，当面板显示纯红色或者纯蓝色画面时，都会出现泛白的现象，影响画面的品质。
