Description

一种双边驱动装置及平板显示器
本发明要求2016年6月16日递交的发明名称为“一种双边驱动装置及平板显示器”的申请号为201610435064.3的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及显示技术领域，尤其涉及一种双边驱动装置及平板显示器。
背景技术
随着显示技术和终端技术的发展，平板显示器在人们的日常生活中得到广泛应用。平板显示器由显示面板和驱动装置组成，驱动装置与显示面板相连接，可以驱动显示面板中的像素点进行显示。一般驱动装置包括驱动器和驱动信号线，通过驱动信号线将驱动器产生的驱动信号传输至显示面板中的像素点。由于信号在驱动信号线中的传输存在RC延迟，距离驱动器较远的像素点接收到驱动信号的时间较晚。
为了避免长时间的延迟，对于较大面积的显示面板，现有技术通常采用双边驱动装置，即在显示面板相对的两边均设置驱动器，每个驱动器产生的驱动信号各传输一半的距离，从而缩短延迟的时间。但是，对于在驱动信号线中间的像素点来说，与两个驱动器的距离都最远，RC延迟最大。当其他像素点已经点亮时，这些位于中间的像素点由于充电不足没有完全点亮，导致显示面板上出现一条“暗带”。

在本实施例中，每条驱动信号线103上的黑点为其中点1031，虚线为上述至少两条驱动信号线103的中点1031的连线。如图1所示，上述至少两条驱动信号线103的中点1031的连线不平行于所述显示面板的特定边缘。优选 地，上述至少两条驱动信号线103的中点1031的连线可以为折线。
具体地，第一源极驱动器101和第二源极驱动器102分别沿着显示面板20的两条相对的边缘排列分布。其中上述特定边缘可以是第一源极驱动器101所沿着排列的边缘或者第二源极驱动器102所沿着排列的边缘。可选地，双边驱动装置10中可包括一对或多对第一源极驱动器101和第二源极驱动器102。
具体实施中，每对第一源极驱动器101和第二源极驱动器102之间通过驱动信号线103连接，驱动信号线103可位于显示面板下方，每条驱动信号线103与显示面板中的一行或一列像素点相连。驱动信号线的中点1031是驱动信号线中距离第一源极驱动器101和第二源极驱动器102都最远的点，与驱动信号线103的中点1031连接的像素点则是整行或整列中RC延迟最严重的像素点。当这些RC延迟最严重的像素点呈直线分布时，液晶面板上将形成一条暗带；而当这些RC延迟最严重的像素点不呈直线分布时，由于人眼的视觉特性，会混淆暗点和亮点，从而使得暗点变得不明显，可避免暗带的出现。
作为一种可行的实施方式，可调整驱动信号线的长度，使不同驱动信号线的长度不一致，从而使驱动信号线的中点连线不平行于显示面板的特定边缘。
可选地，上述至少两条驱动信号线103的中点连线不平行于显示面板20的特定边缘，可以是上述至少两条驱动信号线103的中点在参考线附近的预设距离内随机分布，其中参考线可以是显示面板20中平行于特定边缘的中轴。或者，也可以是上述至少两条驱动信号线103的中点按照预设的规律分布。
在一些可行的实施方式中，相对于所述特定边缘，所述至少两条驱动信号线的中点连线可以呈三角波排列。
具体实施中，可以如图2所示，沿所述特定边缘的方向，使所述至少两条驱动信号线103的中点1031与所述特定边缘之间的距离在预设距离范围内交替递增或递减，以使所述至少两条驱动信号线的中点连线呈三角波排列。
作为一种可行的实施方式，可以如图3所示，沿所述特定边缘的方向，所述至少两条驱动信号线103的中点与所述特定边缘之间的距离可以交替为第一距离D1和第二距离D2，以使所述至少两条驱动信号线的中点与所述特定边缘之间的距离在预设距离范围内交替递增或递减。
其中，图3以显示面板20中第一源极驱动器101所沿着分布的边缘作为特定边缘为例进行说明，应当理解，在实际应用中，特定边缘也可以是显示面 板20中第二源极驱动器102所沿着分布的边缘。具体实施中，上述预设距离范围可以根据垂直边缘的边长进行设置，例如可以是上述垂直边缘边长的1/2、1/3、1/4等。其中，垂直边缘为与上述特定边缘垂直相交的边缘。
在一些可行的实施方式中，如图4所示，相对于所述特定边缘，所述至少两条驱动信号线103的中点连线可以呈梯形波排列。具体地，沿着上述特定边缘的方向，例如从左到右或从右到左，上述至少两条驱动信号线103的中点1031与上述特定边缘之间的距离可以按照“递增、持平、递减、持平、再递增”的规律进行设置，从而使得上述至少两条驱动信号线103的中点连线与参考线形成多个相接且方向交替的梯形。其中优选地，参考线可以是显示面板20中平行于特定边缘的中轴。上述至少两条驱动信号线103的中点1031与该参考线的距离可以根据垂直边缘的边长进行设置，例如最远距离不超过垂直边缘边长的1/4。
作为一种可行的实施方式，沿着上述特定边缘的方向，例如从左到右或从右到左，上述至少两条驱动信号线103的中点1031与上述特定边缘之间的距离还可以按照“递增、持平、递减、再递增”的规律进行设置。此时，如图5所示，上述至少两条驱动信号线103的中点连线可以与参考线形成多个方向相同且相接的梯形。其中，参考线可以平行于上述特定边缘且位于上述中轴附近。可选地，参考线可以位于显示面板20的中轴下方或上方。
在一些可行的实施方式中，如图6所示，相对于所述特定边缘，所述至少两条驱动信号线的中点连线可以交替呈阶梯状递增或阶梯状递减排列。也即，沿着上述特定边缘的方向，例如从左到右或从右到左，上述至少两条驱动信号线103的中点1031与上述特定边缘之间的距离可以按照先重复“递增、持平”若干次，再重复“递减、持平”若干次的规律循环。
在一些可行的实施方式中，如图7所示，相对于所述特定边缘，所述至少两条驱动信号线103的中点连线可以交替呈锯齿状递增或锯齿状递减排列。
在一些可行的实施方式中，如图8所示，所述至少两条驱动信号线103的中点1031还可以在上述中轴附近的一定范围内不规则分布，使得中点连线形成不规则的折线。
本发明实施例中，双边驱动装置包括第一源极驱动器、第二源极驱动器以及至少两条连接第一源极驱动器和第二源极驱动器的驱动信号线，利用人眼的 视觉特性，通过使上述至少两条驱动信号线的中点连线不平行于显示面板的特定边缘来混淆暗点和亮点，从而增强显示面板的亮度均匀性，提高显示质量。
参见图9，为本发明的一个实施例提供的平板显示器的结构示意图。如图9所示，该平板显示器90可包括显示面板901和双边驱动装置902，其中双边驱动装置902为如图1至8所示实施例中所述的双边驱动装置。具体地，双边驱动装置902可用于为显示面板901提供源极驱动信号。
在一些可行的实施方式中，该平板显示器可以为液晶平板显示器，则显示面板901为液晶面板。
在另一些可行的实施方式中，该平板显示器可以为有机电致发光二极管(Organic Light-Emitting Diode，OLED)显示器，则显示面板901为OLED面板。
根据图1至8所示实施例的相关描述可知，本发明实施例的平板显示器可利用人眼的视觉特性，通过使驱动信号线的中点连线不平行于显示面板的特定边缘来混淆暗点和亮点，从而增强显示面板的亮度均匀性，提高显示质量。
以上所述的实施方式，并不构成对该技术方案保护范围的限定。任何在上述实施方式的精神和原则之内所作的修改、等同替换和改进等，均应包含在该技术方案的保护范围之内
