Description

显示面板的驱动方法及包括其的显示装置 技术领域
本发明属于显示技术领域，更具体地说，涉及一种显示面板的驱动方法及包括这种液晶显示面板的显示装置。
背景技术
显示面板，尤其是基于TFT-LCD的液晶显示面板是较普遍应用于电子装置的部件。随着TFT-LCD技术的日渐成熟，对TFT-LCD的成本竞争力要求越来越高，即，应用TFT-LCD的TV市场中陆续出现Dual-gate/Tri-gate结构的液晶显示面板，且能够减少源极集成电路(source IC)通道数，从而降低成本。但是，这种Dual-gate/Tri-gate结构所包括的固有缺陷在于：大大降低了TFT-LCD的充电时间，而这种充电时间的增加随着液晶显示面板的清晰度的增加而体现得越加明显。
在Dual-gate结构中，为了避免闪烁过于严重而一般使用两线反转(2line inversion)驱动方式，但是当由源极线提供的数据电压的极性(polarity)发生变化时，像素电压的变化值较大，而cell内部RC delay(电阻电容对电压变化进行充电导致的电压变化延时现象)严重则会出现部分子像素充电不足而画面偏暗的问题。
为了解决上述亮度偏暗的问题，一般采取WOA(Wire OnArray)做成铜材质走线和/或将WOA走线变宽来降低cell阻抗值，减轻RC delay程度，增大充电效率。但是，若将WOA走线制作成铜材质，需要TFT-LCD制造工艺上，而这种制造工艺的改造以及涉及制造工艺的问题都会产生极大的成本问题，导致产品的成本变高，而若将WOA走线变宽，必然减少面板的显示区域面积，降低了开口率，需要提高背光亮度才能提高面板亮度，仍会导致产品的的成本变高。
发明内容
为克服现有技术的不足，本发明的示例性实施例提供一种能够有效改善画面变暗的显示面板的驱动方法和显示装置。
根据本发明示例性实施例，提供了一种显示面板的驱动方法。所述显示面板包括沿第一方向排列的多条源极线、沿与第一方向垂直的第二方向排列且与所述多条源极线交叉的多条栅极线以及在所述多条源极线与所述多条栅极线交叉处布置而形成二维像素阵列的多个像素。所述显示面板以逐行驱动方式被驱动。所述显示面板的驱动方法可包括如下步骤：针对所述多条源极线中的每一条源极线，确定当前驱动周期提供的数据电压与前一驱动周期提供的数据电压之间是否发生极性变化；当发生了极性变化时，由第j源极线提供的数据电压的极性发生了变化时，基于当前驱动周期提供的数据电压与前一驱动周期提供的数据电压，来确定补偿值；基于确定的补偿值来对当前驱动周期提供的数据电压进行补偿，来确定当前驱动周期提供的最终数据电压。
优选地，确定补偿值的步骤可包括：仅在发生了极性变化时，确定补偿值。
优选地，确定补偿值的步骤可包括：基于当前驱动周期提供的数据电压和前一驱动周期提供的数据电压来计算补偿值；或者，基于当前驱动周期提供的数据电压和前一驱动周期提供的数据电压，从查询表中检索补偿值。

优选地，所述控制器基于当前驱动周期提供的数据电压和前一驱动周期提供的数据电压来计算补偿值，或者，基于当前驱动周期提供的数据电压和前一驱动周期提供的数据电压，从查询表中检索补偿值。
如上所述，针对同一条源极线，基于当前驱动周期提供的数据电压与前一驱动周期提供的数据电压之间是否发生极性变换而基于当前驱动周期提供的数据电压和前一驱动周期提供的数据电压来对当前驱动周期提供的数据电压进行补偿而将经补偿的数据电压提供给相应像素，从而至少能够解决因极性反转导致的画面变暗的问题，进而提高了显示面板的显示品质。
将在接下来的描述中部分阐述本发明另外的方面和/或优点，还有一部分通过描述将是清楚的，或者可以经过本发明的实施而得知。
附图说明
通过下面结合附图进行的对实施例的描述，本发明的上述和/或其它目的和优点将会变得更加清楚，其中：
图1是示出根据本发明示例性实施例的显示装置的框图；
图2为示出图1所示的显示面板的一部分的示图；
图3A和图3B分别为示出现有技术的驱动方法和应用本发明示例性实施例的驱动方法的比较示图；
图4为示出根据本发明示例性实施例的显示面板的驱动方法的流程图。
具体实施方式
现将详细描述本发明的示例性实施例，所述实施例的示例在附图中示出，其中，相同的标号指示相同的部分。以下将通过参照附图来说明所述实施例，以便解释本发明。
图1是示出根据本发明示例性实施例的显示装置1000的框图。参照图1，显示装置1000一般包括显示面板10和显示面板驱动电路。
显示面板10包括以矩阵排列的多个像素并且显示面板10被配置为以帧单位显示图像。显示面板10可以是液晶显示(LCD)面板、发光二极管(LED)显示面板、有机LED(OLED)显示面板、有源矩阵OLED(AMOLED)显示面板，但不限于此。为了便于描述，下面以液晶显示面板作为显示面板10的示例而进行说明。
如图1所示，显示面板10假设为包括沿行方向排列的栅极线G1至Gn，沿列方向排列的源极线S1至Sm、在栅极线G1至Gn和源极线S1至Sm的交叉处形成的各个像素PX。这里，每个像素PX可包括薄膜晶体管(TFT)以及连接到TFT的漏极的相应电容器。
同时，如图1所示，显示装置1000所包括的显示面板驱动电路可包括控制器100、栅极驱动器200和源极驱动器300。
控制器100可从外部(例如，主机装置)接收图像数据DATA1和控制信号CONT，并基于接收到的图像数据DATA1和控制信号CONT来产生用于控制栅极驱动器200和源极驱动器300的控制信号CONT1和CONT2。时序控制器100还可被用于转换从外部提供的图像数据DATA1的格式以符合针对与源极驱动器300相关联的接口的规格。因此，可将转换后的图像数据DATA2从控制器100传递到源极驱动器300。
响应于由控制器100提供的第一控制信号CONT1和第二控制信号CONT2以及图像数据DATA1，栅极驱动器200和源极驱动器300共同地驱动显示面板10的像素PX。这里，第一控制信号CONT1和第二控制信号CONT2可以 是一个或多个控制信号、控制包和/或参考信号(例如，时钟信号、电压参考、参考数据)。
参照图1，栅极驱动器200基于接收到的第二控制信号CONT2来确定驱动所述n条栅极线中的哪条栅极线，即，栅极驱动器200基于接收到的第二控制信号CONT2确定将驱动信号(即，栅极开启信号)施加到所述n条栅极线中的哪条栅极线。栅极驱动器200可将驱动信号(即，栅极开启信号)施加到所述n条栅极线中的相应栅极线，从而连接到所述相应栅极线的像素PX被激活而接收经由m条源极线提供的数据电压(例如，与灰阶值相应的灰度电压)。向所述n条栅极线顺序地提供驱动信号(即，栅极开启信号)来顺序地驱动所述n条栅极线，即，按逐行驱动方式来驱动所述n条栅极线。在下面的描述中，为了便于描述，将驱动信号(即，栅极开启信号)提供给第i条栅极线来激活连接到第i条栅极线的像素PX来使其接收经由m条源极线提供的数据信号的时间段称为第i驱动周期(或，经由第i栅极线提供驱动信号的第i驱动周期)。
源极驱动器300输出针对连接到激活的栅极线的每个像素PX的数据电压。在此，输出到像素PX的数据电压对应于灰度电压(或，灰阶值)。因此，显示面板100可以以水平线或行的单位显示图像。
源极驱动器300响应于第一控制信号CONT1而驱动显示面板10的源极线S1至Sm。源极驱动器300产生与图像数据DATA2相应的数据电压(或，灰度电压)并将该灰度电压经由显示面板10的源极线S1至Sm输出给相应像素PX。
下面参照图2来描述根据本发明示例性实施例的显示面板的驱动的方法。图2为示出图1的显示面板10的一部分的示图。
在图2所示的示例中，像素PX1连接在第(i+1)栅极线G(i+1)和第j源极线Sj的交叉处，像素PX2连接在第i栅极线Gi和第(j+1)源极线S(j+1)的交叉处，像素PX3连接在第(i+1)栅极线G(i+1)和第(j+1)源极线S(j+1)的交叉处，像素PX4连接在i栅极线Gi和第(j+2)源极线S(j+2)的交叉处，像素PX5连接在第(i+1)栅极线G(i+1)和第(j+2)源极线S(j+2)的交叉处，像素PX6连接在i栅极线Gi和第(j+3)源极线S(j+3)的交叉处。
同时，像素PX7连接在第(i+3)栅极线G(i+3)和第j源极线Sj的交叉处， 像素PX8连接在第(i+2)栅极线G(i+2)和第(j+1)源极线S(j+1)的交叉处，像素PX9连接在第(i+3)栅极线G(i+2)和第(j+1)源极线S(j+1)的交叉处，像素PX10连接在第(i+2)栅极线G(i+2)和第(j+2)源极线S(j+2)的交叉处，像素PX11连接在第(i+3)栅极线G(i+3)和第(j+2)源极线S(j+2)的交叉处，像素PX12连接在第(i+2)栅极线G(i+2)和第(j+3)源极线S(j+3)的交叉处。
在图2所示的示例中，像素PX1、PX2和PX3可分别是第一像素的红色子像素、绿色子像素和蓝色子像素，像素PX4、PX5和PX6可分别是第二像素的红色子像素、绿色子像素和蓝色子像素，像素PX7、PX8和PX9可分别是第三像素的红色子像素、绿色子像素和蓝色子像素，像素PX10、PX11和PX12可分别是第四像素的红色子像素、绿色子像素和蓝色子像素。
当经由第i栅极线Gi提供栅极开启信号时，即，在经由第i栅极线Gi提供驱动信号的第i驱动周期中，因像素PX2、像素PX4和像素PX6连接到第i栅极线Gi，因此上述像素PX2、PX4和PX6分别从第(j+1)源极线S(j+1)、第(j+2)源极线S(j+2)和第(j+3)源极线S(j+3)接收相应数据电压。
当经由第(i+1)栅极线G(i+1)提供栅极开启信号，即，经由第(i+1)栅极线G(i+1)提供驱动信号的第(i+1)驱动周期中时，因像素PX1、像素PX3和像素PX5连接到第(i+1)栅极线G(i+1)，因此上述像素PX1、PX3和PX5分别从第(j+1)源极线S(j+1)、第(j+2)源极线S(j+2)和第(j+3)源极线S(j+3)接收相应数据电压。
当经由第(i+2)栅极线G(i+2)提供栅极开启信号，即，经由第(i+2)栅极线G(i+2)提供驱动信号的第(i+2)驱动周期中时，因像素PX8、像素PX10和像素PX12连接到第(i+2)栅极线G(i+2)，因此上述像素PX8、PX10和PX12分别从第(j+1)源极线S(j+1)、第(j+2)源极线S(j+2)和第(j+3)源极线S(j+3)接收相应数据电压。
当经由第(i+3)栅极线G(i+3)提供栅极开启信号，即，经由第(i+3)栅极线G(i+3)提供驱动信号的第(i+3)驱动周期中时，因像素PX7、像素PX9和像素PX11连接到第(i+3)栅极线G(i+3)，因此上述像素PX7、PX9和PX11分别从第(j+1)源极线S(j+1)、第(j+2)源极线S(j+2)和第(j+3)源极线S(j+3)接收相应数据电压。
另外，根据本发明示例性实施例，显示面板100以行反转驱动方式、两行反转驱动方式、点反转驱动方式等反转方式被驱动。例如，如图2所述，第(j+1)源极线分别在第i驱动周期、第(i+1)驱动周期、第(i+2)驱动周期和第(i+3)驱动周期向像素PX2、像素PX3、PX8和PX9提供极性分别为“-”、“-”、“+”和“+”的数据电压。即，在第(i+1)驱动周期与第(i+2)驱动周期之间，数据电压的极性从“-”变化为“+”。
这种极性的变化会导致在向像素PX8提供的数据电压因RC delay而导致其充电不足，从而导致其画面偏暗。
为了解决上述问题，针对同一条源极线，(例如，控制器100)当前驱动周期提供的数据电压与前一驱动周期提供的数据电压之间是否发生极性变换而基于当前驱动周期提供的数据电压和前一驱动周期提供的数据电压来对当前驱动周期提供的数据电压进行补偿而将经补偿的数据电压提供给相应像素。
例如，针对图2所示的第(i+1)源极线S(i+1)，在第i驱动周期和第(i+1)驱动周期所提供的数据电压的极性均为“-”，即，数据电压在第i驱动周期与第(i+1)驱动周期之间未发生极性变化，因此对在第(i+1)驱动周期经由第(i+1)源极线S(i+1)提供给像素PX3的数据电压不进行补偿。相似地，针对第(i+1)源极线S(i+1)，在第(i+2)驱动周期和第(i+3)驱动周期所提供的数据电压的极性均为“+”，即，数据电压在第(i+2)驱动周期与第(i+3)驱动周期之间未发生极性变化，因此对在第(i+3)驱动周期经由第(i+1)源极线S(i+1)提供给像素PX9的数据电压不进行补偿。
但是，针对第(i+1)源极线S(i+1)，在第(i+1)驱动周期和第(i+2)驱动周期所提供的数据电压的极性分别为“-”和“+”，即，数据电压在第(i+1)驱动周期与第(i+2)驱动周期之间发生了极性变化，因此对在第(i+2)驱动周期经由第(i+1)源极线S(i+1)提供给像素PX8的数据电压进行补偿。
由于数据电压的极性发生变化(即，翻转)，控制器100可对当前数据电压V0进行补偿而确定最终数据电压V1，并将该最终数据电压V1提供给相应像素(例如，像素PX8)。
根据本发明的示例性实施例，控制器100可根据极性控制信号POL而判 断数据电压的极性是否发生了变化(即，翻转)。
此外，根据本发明示例性实施例，(例如，控制器100)可根据当前驱动周期的数据电压和前一扫描周期的数据电压来计算针对当前驱动周期的数据电压的补偿值。
此外，根据本发明示例性实施例，可在显示装置的存储装置中预先存储如下面的表1所示的查询表，并当前驱动周期的数据电压和前一扫描周期的数据电压从所述预先存储的查询表检索相应补偿值。

图3A和图3B分别为示出现有技术的驱动方法和应用本发明示例性实施例的驱动方法的比较示图，其中，在图3A示出了根据现有技术的驱动方法的数据电压，图3B示出根据本发明示例性实施例的驱动方法的数据电压。
通过图3A和图3B所示出的数据电压的比较，能够看出，通过应用根据本发明示例性实施例的驱动方法能够有效画面变暗的问题。
图4为示出根据本发明示例性实施例的显示面板的驱动方法的流程图。如上所述，根据本发明示例性实施例的显示面板包括沿第一方向(例如，列方向)排列的m条源极线、沿与第一方向垂直的第二方向(例如，行方向)排列且与所述m条源极线交叉的n条栅极线以及在所述m条源极线与所述n条栅极线交叉处布置而形成二维像素阵列的m×n个像素，其中，m和n是正整数。
根据本发明示例性实施例，所述显示面板按逐行方式以行反转驱动方式、两行反转驱动方式、点反转驱动方式之一被驱动。
在步骤S410，确定经由源极线提供的数据电压是否发生了极性变化。针对所述多条源极线中的每一条源极线，确定当前驱动周期提供的数据电压与前一驱动周期提供的数据电压之间是否发生极性变化。例如，针对图2所示的显示面板100，确定经由第j源极线提供的数据电压的极性相对于由第(i-1)栅极线提供驱动信号的第(i-1)驱动周期，在由第i栅极线提供驱动信号的第i驱动周期是否发生了变化，其中，2≤i≤n，1≤j≤m。
这里，经由源极线提供的数据电压是与灰阶值相应的灰度电压。
当由第j源极线提供的数据电压的极性发生了变化时，在步骤S420当发生了极性变化时，由第j源极线提供的数据电压的极性发生了变化时，基于当前驱动周期提供的数据电压与前一驱动周期提供的数据电压，来确定补偿值。例如，基于第i驱动周期中经由第j源极线提供的数据电压和第(i-1)驱动周期中经由第j源极线提供的数据电压确定补偿值。
在此，基于第i驱动周期中由第j源极线提供的数据电压和第(i-1)驱动周期中由第j源极线提供的数据电压计算补偿值。或者，基于第i驱动周期中由第j源极线提供的数据电压和第(i-1)驱动周期中由第j源极线提供的数据电压，从查询表中检索补偿值。
在步骤S430确定经由源极线提供的最终数据电压并经由源极线将确定的最终数据电压提供给相应像素。这里，基于由第i驱动周期中由第j源极线提供的数据电压和所述补偿值，来确定第i驱动周期中由第j源极线提供的最终数据电压。
另外，根据本发明的示例性实施例，仅在经由源极线提供的数据电压的极性发生了变化时，确定补偿值，即，在经由源极线提供的数据电压的极性未发生了变化时将相应数据电压确定为最终数据电压并经由相应源极线提供给相应的像素。
根据本发明的示例性实施例，针对同一条源极线，当前驱动周期提供的数据电压与前一驱动周期提供的数据电压之间是否发生极性变换而基于当前驱动周期提供的数据电压和前一驱动周期提供的数据电压来对当前驱动周期提供的数据电压进行补偿而将经补偿的数据电压提供给相应像素，从而至少能够 解决因极性反转导致的画面变暗的问题，进而提高了显示面板的显示品质。
此外，根据本发明的上述方法可以被实现为计算机可读记录介质中的计算机代码。本领域技术人员可以根据对上述方法的描述来实现所述计算机代码。当所述计算机代码在计算机中被执行时实现本发明的上述方法。
此外，根据本发明的示例性实施例的液晶面板的驱动装置中的各个单元可被实现为硬件组件。本领域技术人员根据限定的各个单元所执行的处理，可以使用例如现场可编程门阵列(FPGA)或专用集成电路(ASIC)来实现各个单元。
本发明的以上实施例仅仅是示例性的，而本发明并不受限于此。本领域技术人员应该理解：在不脱离本发明的原理和精神的情况下，可对这些实施例进行改变，其中，本发明的范围在权利要求及其等同物中限定。
