本申请实施例属于显示技术领域，尤其涉及一种显示面板的驱动方法、驱动装置及显示装置。
背景技术
随着显示技术的不断发展，液晶面板、显示器等显示设备不断向着轻薄化、大屏化、低功耗、低成本的方向发展。目前，双栅极(Dual Gate)驱动架构，被广泛应用于液晶显示面板的驱动，与传统的驱动架构相比，双栅极驱动架构的电极闸线(gate line)的数量增倍、数据线(data line)的数量减半，从而使得源极驱动芯片(source IC)的数量也相应减少，降低了制造成本。
然而，由于电极闸线数量的增倍，使得双栅极驱动架构中行子像素的数据写入时间减半，导致驱动极性发生反转时，发生极性反转的子像素会由于数据延时而导致其液晶充电时间不足，从而使液晶显示面板出现明暗条纹或者网格现象。

具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
本申请的说明书和权利要求书及上述附图中的术语“包括”以及它们任何变形，意图在于覆盖不排他的包含。例如包含一系列步骤或单元的过程、方法或系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，术语“第一”、“第二”和“第三”等是用于区别不同对象，而非用于描述特定顺序。
如图1所示，本申请的一个实施例提供一种基于双栅极驱动架构的显示面板100，其包括至少一个子像素单元131，子像素单元131包括m行×n列子像素，至少一个子像素单元131规则排列构成包括M行×N列子像素的像素阵列130，像素阵列130中的M行子像素由源极驱动芯片120驱动，N列子像素由栅极驱动芯片110驱动，其中，M≥m≥1，N≥n≥1且M、N、m和n均为正整数。
在具体应用中，像素阵列中的每行子像素均包括多组子像素，每组子像素均包括依次排列的第一颜色子像素、第二颜色子像素和第三颜色子像素，位于同一列的子像素的颜色均相同，第一颜色子像素、第二颜色子像素和第三颜色子像素中至少有一个为红色子像素、至少有一个为绿色子像素且至少有一个为蓝色子像素。
在本申请的一个实施例中，显示面板采用双栅极驱动架构结合两线反转(2line inversion)方式，因此，每组子像素中，必定有相邻的两个子像素的极性是 第一极性且另外一个子像素的极性是第二极性，第一极性和第二极性中一个为正极性、一个为负极性，并且同一行子像素中，每隔两个子像素极性反转一次；同一列子像素中，相邻子像素的极性不同。
在具体应用中，基于上述双栅极驱动架构结合两线反转方式，每个子像素单元所包括的子像素的行数m＝2，像素阵列中每个子像素单元的颜色排列规则和极性排列规则都是相同的。
图1中示例性的示出M＝4、N＝12、m＝2且n＝12时的像素阵列130，即示出一个包括4行(图中表示为S1～S4)×12列(图中表示为G1～G12)的像素阵列，第一颜色子像素为红色子像素、第二颜色子像素为绿色子像素、第三颜色子像素为蓝色子像素；图1中，“+”表示正极性，“-”表示负极性，R表示红色子像素，G表示绿色子像素，B表示蓝色子像素。
如图2所示，本申请的一个实施例提供一种显示面板的驱动方法，其包括：
步骤S10：获取当前子像素的位置信息以及用于对当前子像素进行驱动的驱动数据。
在具体应用中，当前子像素的位置信息具体是指当前子像素在显示面板的像素阵列中所处的行数和列数，由于显示面板的像素阵列中每个子像素的颜色都是已知的，因此，根据子像素的位置信息就可以获知子像素的颜色；子像素的驱动数据具体是指用于对子像素的驱动电压进行控制的数据，子像素的驱动数据用以实现对子像素的亮度控制，驱动数据的数值大小与驱动电压和亮度正相关。
步骤S20：根据所述位置信息，在第一参数查找表中查找与所述位置信息对应的判断参数。
在具体应用中，判断参数用于判断当前子像素的驱动数据是否需要被补偿，若利用该驱动数据对子像素进行驱动，会造成子像素偏暗，则说明该驱动数据需要被补偿，否则，说明该驱动数据不需要被补偿。
在本实施例中，判断参数具体包括用于表征驱动数据不需要被补偿的第一 参数和用于表征驱动数据需要被补偿的第二参数。
在具体应用中，第一参数具体可以为数值1，第二参数具体可以为数值0，在其他实施例中，第一参数和第二参数也可以等效替换成其他具有同等含义表示功能的数值或函数。
在具体应用中，由于事先已知像素阵列中每个位置的子像素的显示特性，因此，可以根据子像素的位置，来获知子像素的显示特性，进而获知子像素是否需要被补偿。在一个实施例中，可以通过子像素的位置信息来查找判断参数，第一参数查找表即是根据子像素的位置信息和判断参数构建的查找表。
在一个实施例中，子像素单元中的子像素和第一参数查找表中的判断参数按照排列位置一一对应，即位置相同的子像素和判断参数相互对应。
在一个实施例中，第一参数查找表可以为显示查找表(LUT，look-up-table)，显示查找表具有输入数据即根据输入数据查找对应的输出数据的功能，第一参数查找表还可以是具有同等功能的其他数据表或随机存储记忆体(Random Access Memory，RAM)类存储介质。
在一个实施例中，步骤S20之前还包括：
预先设置并存储第一参数查找表。
如图3所示，本申请的一个实施例示例性的示出一个包括2行×12列判断参数的第一参数查找表，该表中R表示红色子像素、G表示绿色子像素、B表示蓝色子像素、0表示第一参数、1表示第二参数。
步骤S30：若所述判断参数为第一参数，则直接输出所述驱动数据。
在具体应用中，第一参数用于表征驱动数据不需要被补偿，因此，当判断参数为第一参数时，可以直接输出该驱动数据以驱动子像素，此时不会造成子像素偏暗的现象。
步骤S40：若所述判断参数为第二参数，则根据所述位置信息和所述驱动数据，在第二参数查找表中查找补偿驱动数据并输出，所述第二参数查找表与所述位置信息对应，所述补偿驱动数据与所述驱动数据对应。
在具体应用中，第二参数用于表征驱动数据需要被补偿，因此，当判断参数为第二参数时，需要对驱动数据进行补偿之后才能输出用于驱动子像素，以避免造成子像素偏暗的现象。
在一个实施例中，第二参数查找表可以为显示查找表(LUT，look-up-table)，其还可以是具有同等功能的其他数据表或随机存储记忆体(Random Access Memory，RAM)类存储介质。
在具体应用中，通过输出补偿驱动数据来驱动子像素，可以解决子像素偏暗的现象。由于本实施例中主要是为了解决发生极性反转时，子像素偏暗的情况，因此，通过第二参数查找表查找到的驱动数据的数值会比原本的数值大。
在一个实施例中，步骤S40之前还包括：
预先设置并存储第二参数查找表。
本实施例通过获取当前子像素的位置信息，以及用于对当前子像素进行驱动的驱动数据，并在第一参数查找表中查找与位置信息对应的判断参数，以根据判断参数的数值确定驱动数据是否需要被补偿，若需要被补偿，则在第二参数查找表中查找补偿驱动数据并输出，若不需要被补偿，则直接输出驱动数据，可以有效消除液晶显示面板的明、暗条纹或者网格现象。
在一个实施例中，第二参数查找表包括第一补偿参数查找表、第二补偿参数查找表和第三补偿参数查找表，针对不同颜色的子像素使用不同的补偿参数查找表。
如图4所示，在本申请的一个实施例中，步骤S40具体包括：
步骤S41：若所述位置信息对应的子像素为第一颜色子像素，则在所述第一补偿参数查找表中查找所述补偿驱动数据并输出。
在一个实施例中，步骤S41之前包括：
预先设置并存储第一补偿参数查找表。
在一个实施例中，步骤S41具体包括：
在Mod(N，3)＝1时，在第一补偿参数查找表中查找与所述驱动数据对 应的补偿驱动数据并输出，其中，N为显示面板所包括的子像素的列数。

在Mod(N，3)＝2时，在第二补偿参数查找表中查找与所述驱动数据对应的补偿驱动数据并输出，其中，N为显示面板所包括的子像素的列数。
步骤S43：若所述位置信息对应的子像素为第三颜色子像素，则在所述第三补偿参数查找表中查找所述补偿驱动数据并输出。
在一个实施例中，步骤S43之前包括：
预先设置并存储第三补偿参数查找表。
在一个实施例中，步骤S43具体包括：
在Mod(N，3)＝0时，在第三补偿参数查找表中查找与所述驱动数据对应的补偿驱动数据并输出，其中，N为显示面板所包括的子像素的列数。
在本实施例中，Mod(number，divisor)函数表示求余函数，其中，number表示被除数，divisor表示除数。
在一个实施例中，第一补偿参数查找表、第二补偿参数查找表和第三补偿参数查找表均可以为显示查找表(LUT，look-up-table)，还可以是具有同等功能的其他数据表或随机存储记忆体(Random Access Memory，RAM)类存储介质。
在一个实施例中，第一颜色子像素为红色子像素，第二颜色子像素为绿色子像素，第三颜色子像素为蓝色子像素；第一补偿参数查找表为红色子像素补偿参数查找表，第二补偿参数查找表为绿色子像素补偿参数查找表，第三补偿参数查找表为蓝色子像素补偿参数查找表。
如图5所示，本申请的一个实施例示例性的示出了红色子像素补偿参数查 找表R、绿色子像素补偿参数查找表G和蓝色子像素补偿参数查找表B；其中，红子像素补偿参数查找表R左侧的数字0、1、2、……、254和255表示子像素的驱动数据大小，右侧的R(0)、R(1)、R(2)、……、R(254)和R(255)表示补偿驱动数据的大小，绿色子像素补偿参数查找表和蓝色子像素补偿参数查找表的参数表示规则与红色子像素补偿参数查找表相同。

在一个实施例中，驱动装置200还包括：

本实施例通过获取当前子像素的位置信息以及用于对当前子像素进行驱动的驱动数据，并在第一参数查找表中查找与位置信息对应的判断参数，以根据判断参数的数值确定驱动数据是否需要被补偿，若需要被补偿，则在与位置信息对应的第二参数查找表中查找与驱动数据对应的补偿驱动数据并输出，若不需要被补偿，则直接输出驱动数据，可以有效消除液晶显示面板的明暗条纹或者网格现象。
