Description

显示面板的调节方法及调节装置、显示装置 技术领域
本发明属于显示技术领域，具体涉及一种显示面板的调节方法及调节装置、显示装置。
背景技术
对于薄膜晶体管-液晶显示器(Thin Film Transistor-Liquid Crystal Display，简称TFT-LCD)，常用的对液晶显示面板的闪烁(Flicker)问题进行调节的方法有两种：第一种是通过可调电阻调节液晶显示面板的公共电压VCOM的大小；第二种是通过I2C(Inter-Integrated Circuit，内置集成电路)接口对VCOM电压进行调节。
这两种方法都能够提高用户的视觉体验，使液晶显示面板在闪烁画面下的闪烁不明显，达到人眼能够接受的程度。但是，在某些特定画面(指与闪烁画面具有相同像素结构的画面)下人眼还是能感觉到画面发生闪烁。
为了在某些特定画面下使人眼感觉不到画面发生闪烁，有的面板厂商通过时序控制器(TCON)监测发生闪烁画面的像素结构，通过一些TCON设置直接改变液晶的翻转方式，使人眼在这些特定画面下几乎感觉不到画面闪烁。
但是这种方法的缺点是，对于翻转后的像素结构，其对应的VCOM依旧可能是偏离理想态的，需要对VCOM进一步进行调节。然而，在量产阶段的闪烁画面下，由于改变了液晶的翻转方式使人眼在特定画面下无法看到闪烁画面，因此操作人员无法进行调节。也就是说，画面的显示品质在本质上并没有得到提高，甚至在显示一些正常画面时也会受到影响。

根据本发明的实施例，所述预设范围为所述比值可以为大于50％。
根据本发明的实施例，对所述显示面板的至少部分数据线上的所输入的数据电压的原始极性进行翻转的步骤可以包括：通过改变POL的参数值、SQINV的参数值或H2POL的参数值中的一种或多种，使数据电压的原始极性翻转。

附图说明
附图是用来提供对本发明的进一步理解，并且构成说明书的一部分，与下面的具体实施方式一起用于解释本发明，但并不构成对本发明的限制。在附图中：
图1为根据本发明的实施例的显示面板的调节方法的流程示意图；
图2为根据本发明的实施例的显示面板的像素结构示意图；
图3为图2的显示面板显示闪烁画面对应的闪烁像素结构；
图4为图3闪烁像素结构在极性翻转后的像素结构；以及
图5为根据本发明的实施例的显示面板的调节装置的结构示意图。
具体实施方式
为使本领域技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明作进一步详细描述。
图1为根据本发明的实施例的显示面板的调节方法的流程示意图。
参照图1，根据本发明的实施例的显示面板的调节方法，包括：
步骤S1，对显示面板所显示的画面进行检测，以确定所显示的画面是否为闪烁画面。
根据本发明的实施例，步骤S1可以包括对显示面板的像素结构进行检测，以确定所显示的画面是否为闪烁画面，并且可以具体包括：
步骤S11，检测显示面板的像素结构中是否存在与预存的闪烁画面对应的闪烁像素结构。
图2为根据本发明的实施例的显示面板的像素结构示意图。
在本发明的上下文中，术语“像素结构”表示显示面板的各个像素(或子像素)通过连接至各条栅线和数据线所组成的结构。参照图2，栅线G1至G4在水平方向上延伸，以对设置在各个子像素(例如，红色子像素R、绿色子像素G和蓝色子像素B)中的TFT的栅极进行控制。数据线S1至S7在竖直方向上延伸，以分别连接至设置在各个子像素中的TFT的源极。图2以Column+Z像素结构为例示出了显示面板的像素结构，即，每条栅线控制对一行子像素进行控制，数据线在奇数行连接至设置在其右侧的TFT的源极，并且在偶数行连接至设置在其左侧的TFT的源极，设置各个子像素中的TFT相对于数据 线在列方向上呈Z子型排列。然而，本发明构思不限于此，可以采用其他排列和/或连接方式的像素结构。
图3为图2的显示面板显示闪烁画面对应的闪烁像素结构。
在本发明的上下文中，术语“闪烁像素结构”表示显示面板在显示闪烁画面时由各个像素(或子像素)的显示内容所构成的结构性图案。在图2示出的Column+Z像素结构的情况下，通常采用跳过1点(Skip 1DOT)图案或者子像素Skip 1DOT图案作为闪烁画面。如图3所示，在每行像素中的相邻像素的极性相反，并且每列像素中的相邻像素的极性也相反，即，设置在相邻数据线上的极性相反。此外，在同一行中，相邻的两个像素中的一个像素显示正常颜色(例如，红色(R)、绿色(G)和蓝色(B))而另一个像素显示灰色或黑色，并且在同一列中，相邻的两个像素中的一个像素显示正常颜色而另一个像素显示灰色或黑色。然而，本发明构思的闪烁像素结构不限于此。根据本发明的显示面板的调节方法可以对显示面板的全部像素结构进行检测，以检测出显示面板的像素结构中是否存在上述闪烁像素结构。对应于像素架构的闪烁画面可以是预先储存的。此外，针对不同的显示面板的像素结构可以预先存储与之对应的闪烁画面。
步骤S12，当存在闪烁像素结构时，计算闪烁像素结构的数量与显示面板的所有像素结构的数量的比值，并且判断所述比值是否在预设范围内。即，当检测出显示面板的像素结构中存在闪烁像素结构之后，先要计算出与闪烁像素结构对应的闪烁画面与显示面板的所显示的画面之间的比值，再判断该比值是否在预设范围内。
预设范围可以为闪烁像素结构的数量与显示面板的所有像素结构的数量的比值大于50％。然而，本发明构思不局限于此，并且可根据实际情况对预设范围进行设置。
步骤S13，当所述比值在预设范围内时，确定所显示的画面为闪烁画面。
也就是说，在本实施例中，当与闪烁像素结构对应的闪烁画面与显示面板所显示的画面的比值大于50％时，确定显示面板所显示的画面整体上为闪烁画面。
步骤S2，当检测出所显示的画面为闪烁画面时，对显示面板的至少部分数据线上的所输入的数据电压的原始极性进行翻转。
需要说明的是，本实施例中所述的数据电压的原始极性是指数据线驱动IC在显示面板开始进行显示时向数据线输入的数据电压的极性。当显示面板显示的画面为闪烁画面时，通过对数据线上所输入的数据电压的原始极性进行翻转，可改变该数据线控制的像素所对应的液晶分子的翻转方式，以使人眼看不到画面的闪烁。
对显示面板的至少部分数据线上的所输入的数据电压的原始极性进行翻转的方式可以包括：通过改变POL的参数值、SQINV的参数值或H2POL的参数值中的一种或多种，使数据电压的原始极性翻转。
需要说明的是，POL(polarity inverting input)是指水平极性控制信号，即，直接对数据线的极性进行控制；SQINV(square inversion)对水平方向POL的翻转方式进行选择，SQINV为“H”时，水平翻转方式为2点翻转，SQINV为“L”时，水平翻转方式为1点翻转；H2POL(polarity control)对POL是否翻转进行控制，当H2POL为“L”，POL翻转，H2POL为“H”时，POL不翻转。需要注意的是，当采用改变POL的参数值对数据线的极性进行控制时，所有数据线的数据电压的原始极性都被翻转，当采用改变SQINV的参数值或H2POL对数据线的极性进行控制时，并不是所有数据线的数据电压的原始极性都被翻转。
以图2所示的显示面板的像素结构为例，通过改变POL的参数值、SQINV的参数值或H2POL的参数值中的一种或多种，使数据电压的原始极性翻转后的具体情况如表1所示。
表1
POL SQINV H2POL S1 S2 S3 S4 S5 …
L L L - + - + - …
H L L + - + - + …
L H L - + + - - …
L L H + - + - + …
H H L + - - + + …
H L H - + - + - …
L H H + - - + + …
H H H - + + - - …
S1为“+”，代表与数据线S1相连的像素(或子像素)的极性均为正；S1为“-”，代表与数据线S1相连的像素(或子像素)的极性均为负，依次类推。另外，参数值为“L”，代表维持原始值，即无动作；参数值为“H”，代表有动作，进行翻转。以表1中的一种翻转方式为例，如POL为“L”，SQINV为“H”，H2POL为“L”，则图3所示的闪烁像素结构在翻转后如图4所示。
步骤S3，对I2C接口进行扫描，并判断是否有公共电压的写入。
为了对显示面板的非理想态的公共电压进行调整，操作人员通过I2C接口写入调整后的公共电压。因此，如果有公共电压被写入，则说明此时需要对显示面板的公共电压进行调节。
步骤S4，当判断出通过I2C接口有公共电压的写入时，将数据线上的数据电压的极性恢复至原始极性。
在判断出通过I2C接口有公共电压被写入后，对经步骤S2翻转后的数据电压的极性进行第二次翻转，以恢复至其原始极性，从而使人眼能够再次看到画面的闪烁。通过I2C接口写入的公共电压能够对偏离理想态的公共电压进行调节，以使其接近或等于理想态的公共电压，在本质上实现提高画面的显示品质。
本实施例的显示面板的调节方法，一方面，在只需要调整画面闪烁而不需要提高画面的显示品质时，可以通过改变数据电压的原始极性的方式来改变液晶的翻转方式，从而使液晶显示面板在显示一些特殊画面时使人眼几乎感觉不到闪烁；另一方面，在需要对画面闪烁进行调节以提高画面的显示品质时，可以通过将数据电压的极性恢复至其原始极性来对改变的液晶翻转方式进行还原，从而使操作人员能够看到画面闪烁，以便使操作人员能够对闪烁画面进行调整，进而从根本上提升画面品质。
图5为根据本发明的实施例的显示面板的调节装置的结构示意 图。
参照图5，根据本发明的实施例的显示面的调节装置可以包括：翻转电路1、扫描电路2、控制器电路3和检测电路4。检测电路4用于对显示面板所显示的画面进行检测，以确定所显示的画面是否为闪烁画面。当检测出所显示的画面为闪烁画面时，翻转电路1对显示面板的至少部分数据线上的所输入的数据电压的原始极性进行翻转。扫描电路2用于对I2C接口进行扫描，并判断是否有公共电压的写入。当判断出通过I2C接口有公共电压的写入时，控制器电路3将所述至少部分数据线上的数据电压的极性恢复至原始极性。
根据本发明的实施例，检测电路4可以对显示面板的像素结构进行检测，以确定所显示的画面是否为闪烁画面。如图5所示，检测电路4可以包括：检测子电路41、计算子电路42和判断子电路43。检测子电路41用于检测显示面板的像素结构中是否存在与预存的闪烁画面对应的闪烁像素结构。当检测子电路41检测到存在闪烁像素结构时，计算子电路42计算闪烁像素结构的数量与显示面板的所有像素结构的数量的比值。判断子电路43用于判断所述比值是否在预设范围内。当所述比值在预设范围内时，可以确定所显示的画面为闪烁画面。
根据本发明的实施例，翻转电路1可以通过改变POL的参数值、SQINV的参数值或H2POL的参数值中的一种或多种，使数据电压的原始极性翻转。
应当认识到，本发明的各个电路和子电路模块或各个步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于本文的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
根据本发明的实施例，还提供了一种显示装置，包括显示面板 和根据本发明的显示面板的调节装置。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
