Description

一种液晶面板的灰阶电压补偿方法、电路及液晶面板 【技术领域】
本发明涉及液晶面板显示技术领域，特别是涉及一种液晶面板的灰阶电压补偿方法、一种用于液晶面板的电路及一种液晶面板。
【背景技术】
栅极(Gate)扫描电压受面内相移电路(RC，Resistance-Capacitance Circuits)负载影响导致扫描线的压降在液晶面板不同显示区域有所不同。由于馈通效应(Feed Through Effect)的存在，不同的压降导致不同显示区域的像素电压关于公共电压不对称，即影像残留(IS，Image Sticking)程度不同。
当今液晶面板为了节省成本普遍都采用一个公共电压的设计，通过调节公共电压抵消馈通效应造成的像素电压关于公共电压不对称的现象，可初步改善影像残留，但是由液晶面板不同显示区域的馈通效应不同，本申请发明人发现对于采用一个公共电压的液晶面板，调节公共电压只能保持整个液晶面板的部分显示区域影像残留最小。
【发明内容】
本发明实施方式提供了一种液晶面板的灰阶电压补偿方法、一种用于液晶面板的电路及一种液晶面板，旨在解决现有无法通过调节公共电压将整个液晶面板区域的影像残留调整到最小的问题。

所述驱动电路还用于使得最终确定的所述公共电压和所述像素电压输出。
为解决上述技术问题，本发明实施方式的第三方面，提供一种液晶面板，包括用于液晶面板的电路，所述液晶面板包括：多条相互平行的栅线、多条相互平行且与所述栅线垂直绝缘相交的数据线、多个位于所述栅线与所述数据线相交处的薄膜晶体管、多个像素电极和一个公共电极，所述像素电极经由所述薄膜晶体管与所述数据线相连，并与所述公共电极相对设置；

所述驱动电路还用于使得最终确定的所述公共电压和所述像素电压输出。
本发明提供的技术方案与现有技术相比存在的有益效果是：区别于现有技术中只调整整个液晶面板的公共电压，或者对各个显示区域的相互独立的公共电压分别进行调整且对各个显示区域的像素电压分别进行调整，本发明实施方式提供的液晶面板的灰阶电压补偿方法，对于为节约成本可以采用一个公共电 压的液晶面板，通过调整公共电压和液晶面板至少两个不同显示区域的至少部分像素电压中的至少一个，确定公共电压和像素电压，使得液晶面板至少两个不同显示区域的所有像素的正负极性的像素电压均相对于公共电压对称，并且至少两个不同显示区域的所有像素的正极性的最大像素电压相等，而后输出公共电压和像素电压，最终将整个液晶面板的影像残留降到最小，相比于现有技术，本发明在节约液晶面板成本的同时，极大地提高了液晶面板的显示性能。

【具体实施方式】
参阅图1，图1示出了本发明第一实施方式提供的一种液晶面板的灰阶电压补偿方法的流程，为了便于说明，图1仅示出了与本发明实施方式相关的部分，图1示例的液晶面板的灰阶电压补偿方法包括步骤S101和步骤S102：
S101，确定公共电压和像素电压，所述像素电压是正负极性交替反转电压，使得所述液晶面板至少两个不同显示区域的所有像素的正负极性的所述像素电 压均相对于所述公共电压对称，并且所述至少两个不同显示区域的所述所有像素的正极性的最大像素电压相等，其中，所述公共电压经过调整，和/或所述液晶面板至少两个不同显示区域的至少部分所述像素电压经过补偿。
需要说明的是，液晶面板刚开始工作时，存在一个原始公共电压，且液晶面板的每个像素也都存在一个原始像素电压，像素电压是正负极性交替反转电压，公共电压和像素电压共同决定了液晶面板输出灰阶。
参阅图2，图2示出了本发明第一实施方式提供的一种液晶面板的灰阶电压补偿方法中液晶面板结构，图2中最底端两个黑色长方形11表示数据驱动电路，灰色区域12表示液晶面板的基板，介于数据驱动端和基板之间的黑色小长方形14表示给面板充电的电极，基板两侧竖直排列的带黑色边框的长方形13表示栅极驱动电路，扫描线沿着基板水平分布与栅极驱动电路13相连，数据线竖向分布，图2中①、②、③表示人为根据通电后液晶面板的显示信息(例如亮度)及补偿灰阶电压的需要将液晶面板划分为五个显示区域的标识，黑色点画线15表示相邻显示区域的分界，需要强调的是，此种划分并不是液晶面板在物理上进行划分，只是为了说明的需要在显示上的人为示例性划分。
参阅图3，图3示出了本发明第一实施方式提供的一种液晶面板的灰阶电压补偿方法中液晶面板输出的理想灰阶电压，图3中纵轴表示电压值的大小，两条横向的黑色实线16表示输出的灰阶电压(例如为127灰)，横向灰色实线17表示原始公共电压VCOM，带双向箭头的竖向黑色实线18表示液晶面板的原始像素电压Δv，因为像素电压为正负极性反转电压，故在原始公共电压以上电压值增大的方向为正极性的原始像素电压+Δv，而在原始公共电压以下电压值减小的方向施加的为负极性的原始像素电压-Δv，图3中①、②、③表示图2中液晶面板从左向右或从右向左的三个显示区域，黑色点画线15表示相邻显示区域的分界。理想状态下，原始像素电压关于原始公共电压对称，即液晶面板所有显示区域中正负极性反转的原始像素电压的值均为Δv，在原始公共电压和原始像素电压同时作用下，整个液晶面板的显示信息(例如亮度)相同，此时液晶面板的显示性能最好。
参阅图4，图4示出了本发明第一实施方式提供的一种未经补偿的液晶面板的灰阶电压补偿方法中液晶面板输出的实际灰阶电压。图4中显示区域①、②、③中带双向箭头的竖向黑色实线19表示由于相移电路(RC， Resistance-Capacitance Circuits)负载影响和馈通效应(Feed Through Effect)的存在，由原始像素电压变化后的像素电压，黑色横向虚线16表示图3中理想状态下的灰阶电压(由于实际情况下，达不到图3中的灰阶电压，但为了对比观察及描述的方便，以虚线的形式表示)，显示区域①、②、③中黑色横向实线20表示在原始公共电压和由于馈通效应变化后的像素电压的作用下的灰阶电压，其余符号与图3中含义相同，在此不再赘述。从图4中可知，变化后的像素电压关于原始公共电压不对称，如此，使得整个液晶面板的显示信息(例如亮度)在显示区域①、②、③中不同，而且输出电压都达不到理想的127灰。而且，显示区域①、②、③中像素电压下降值(记为Δft)依次减小，其原因为栅极电压在扫描线上的不同位置有RC延迟现象，邻近栅极驱动电路的位置延迟少，则Δvgate值大，远离栅极驱动电路的位置延迟大，Δvgate值小，而像素电压下降值Δft为：
Figure PCTCN2017097744-appb-000001
其中，Δvgate表示栅极电压开启电压和关闭电压的压差，即von-voff；Cgd表示TFT寄生电容；Cs表示存储电容；Clc表示液晶电容。需要强调的是，显示区域①、②、③中的实际像素电压下降值Δft通过以上公式无法求得，在此只是说明原理，而且，液晶面板显示信息的真实变化并不是突变的，而是相对连续渐变的，在此只是为了说明的需要，对液晶面板人为划分显示区域。
需要说明的是，S101中确定的公共电压是原始公共电压经过不断调整后得到的，此确定的公共电压的值的大小是通过反复尝试后的一个经验值，对于不同的液晶面板可能会有不同。
需要说明的是，S101中“对称”和“相等”并非数学中严格意义上的对称和相等，对称指的是同一显示区域中正负极性反转的像素电压的差值在第一预设范围内，相等指的是两个不同显示区域中正极性的最大像素电压的差值在第二预设范围内，事实上，这两个预设范围均与人眼对液晶面板显示信息(例如亮度)的感知相关，理论上，同一显示区域的像素电压正负极性反转时，只要人眼感受不到该显示区域发生闪烁现象，即说明像素电压已经关于公共电压对称，只要人眼感受不到两个不同显示区域存在显示信息(例如亮度)的差别，即说明达到了两个不同显示区域的所有像素的正极性的最大像素电压相等。事实上，在前述对称和相等的前提下，该两个不同显示区域的所有像素的负极性 的最大像素电压也相等。需要强调的是，虽然不同的人对液晶面板显示信息(例如亮度)的感知存在差别，但正常人眼感知到的显示信息(例如亮度)在某个确切的范围内。
需要说明的是，对公共电压进行调整和/或对像素电压进行补偿，确定公共电压和/或像素电压是一个不断尝试、微调，使得同一显示区域人眼感受不到闪烁，而且两个不同显示区域人眼感受不到最大亮度不同，最终整个液晶面板至少两个不同显示区域均匀显示的过程。
需要说明的是，S101中公共电压经过调整，和/或液晶面板至少两个不同显示区域的至少部分像素电压经过补偿，是根据液晶面板至少两个不同显示区域的所有像素的正负极性的所述像素电压均相对于所述公共电压对称，并且所述至少两个不同显示区域的所述所有像素的正极性的最大像素电压相等这一结果而具体定的。并不是指公共电压必须经过调整或者是像素电压必须经过补偿。例如，公共电压保持不变，对不同显示区域的正负极性像素电压进行补偿，从而达到液晶面板至少两个不同显示区域的所有像素的正负极性的所述像素电压均相对于所述公共电压对称，并且所述至少两个不同显示区域的所述所有像素的正极性的最大像素电压相等。再如，调整公共电压使得液晶面板至少两个不同显示区域的其中某个显示区域的所有像素的正负极性的所述像素电压均相对于所述公共电压对称，再对液晶面板至少两个不同显示区域的其中另一个或多个显示区域的正负极性像素电压进行补偿，从而也达到液晶面板至少两个不同显示区域的所有像素的正负极性的所述像素电压均相对于所述公共电压对称，并且所述至少两个不同显示区域的所述所有像素的正极性的最大像素电压相等。
可选的是，本发明实施方式中，公共电压经过调整可由如下步骤S1010、步骤S1011、步骤S1012、步骤S1013和步骤S1014实现：
S1010，不断调整所述公共电压的值并输出，同时对应一个所述公共电压的值交替设置所述像素电压为正极性电压、负极性电压。
例如，将公共电压的值由原来的2调整为3且输出，此时像素电压相对调整后的公共电压3正负极性交替反转。
S1011，每调整一次公共电压的值并输出后，采集包括液晶面板的至少两个不同显示区域在内的两张图像，分别记为第一正图像和第一负图像，第一正图像对应正极性电压的像素电压，第一负图像对应负极性电压的像素电压。
例如，将公共电压的值由原来的2调整为3且输出后，若像素电压为正极 性时，采集图2中显示区域②和③在内的图像，记为第一正图像，若像素电压为负极性时，也采集图2中显示区域②和③在内的同样显示区域的图像，记为第一负图像。
S1012，对第一正图像亮度值和第一负图像亮度值的第一相似度进行计算。
需要说明的是，第一相似度是度量第一正图像和第一负图像亮度方面的相似性。
可选的是，对第一正图像亮度值和第一负图像亮度值的第一相似度进行计算具体包括计算第一正图像和第一负图像对应像素的亮度值的差的绝对值的期望和标准差。
例如，第一正图像第一像素的亮度值为100，第二像素的亮度值为98，......，第一负图像对应第一像素的亮度值为99，对应第二像素的亮度值为101，......，则第一像素的亮度值的差的绝对值为1，第二像素的亮度值的差的绝对值为2，......，再计算前述所有像素绝对值的期望和标准差，期望可以为平均值，也可以为加权平均值。
需要说明的是，表征两张图像相似度的指标还可以为方差、标准偏差等。
S1013，将第一相似度的计算结果与预设阈值范围进行比较。
需要说明的是，预设阈值范围是一个经验取值范围，是通过大量尝试得到的。
例如，预设阈值范围包括期望的预设阈值范围和标准差的预设阈值范围。
S1014，直到第一相似度的计算结果符合预设阈值范围，停止调整公共电压的值。
例如，若S1012中计算的期望和标准差均落入各自的预设阈值范围内，说明当前采集图像表示的液晶面板区域已经符合调整的标准，则停止调整公共电压的值。
可选的是，本发明实施方式中，液晶面板至少两个不同显示区域的至少部分所述像素电压经过补偿可由如下步骤S1015、步骤S1016、步骤S1017、步骤S1018和步骤S1019实现：
S1015，不断补偿像素电压的值并输出，像素电压为正极性电压和负极性电压，各补偿一次。
可选的是，相邻正极性电压和负极性电压给予相同的补偿值。
S1016，各补偿一次像素电压的值并输出后，采集包括液晶面板的至少两个 不同显示区域在内的两张图像，分别记为第二正图像和第二负图像，第二正图像对应正极性电压的像素电压，第二负图像对应负极性电压的像素电压。
例如，将原始正极性像素电压的值由原来的97补偿为107且输出后，采集图2中两个不同显示区域①在内的图像，记为第一正图像，像素电压反转为负极性像素电压时，将原始负极性像素电压的值由原来的-157补偿为-147且输出后，也采集图2中两个不同显示区域①在内的同样显示区域的图像，记为第一负图像。
S1017，对第二正图像亮度值和第二负图像亮度值的第二相似度进行计算。
可选的是，对第二正图像亮度值和第二负图像亮度值的第二相似度进行计算包括计算第二正图像和第二负图像对应像素的亮度值的差的绝对值的期望和标准差。
例如，第二正图像第一像素的亮度值为100，第二像素的亮度值为98，......，第二负图像对应第一像素的亮度值为99，对应第二像素的亮度值为101，......，则第一像素的亮度值的差的绝对值为1，第二像素的亮度值的差的绝对值为2，......，再计算前述所有像素绝对值的期望和标准差，期望可以为平均值，也可以为加权平均值。
需要说明的是，表征两张图像相似度的指标还可以为方差、标准偏差等。
S1018，将第二相似度的计算结果与预设阈值范围进行比较。
需要说明的是，预设阈值范围是一个经验取值范围，是通过大量尝试得到的。
例如，预设阈值范围包括期望的预设阈值范围和标准差的预设阈值范围。
S1019，第二相似度的计算结果符合预设阈值范围，停止补偿像素电压的值。
例如，若S1017中计算的期望和标准差均落入各自的预设阈值范围内，说明当前采集图像表示的液晶面板区域已经符合调整的标准，则补偿像素电压的值。
可选的是，公共电压经过调整，和液晶面板至少两个不同显示区域的至少部分像素电压经过补偿包括公共电压先经过调整，而后液晶面板至少两个不同显示区域的至少部分像素电压再经过补偿。
需要说明的是，以上关于步骤S1010、步骤S1011、步骤S1012、步骤S1013、步骤S1014、步骤S1015、步骤S1016、步骤S1017、步骤S1018、步骤S1019的说明均可以用于公共电压先经过调整，而后液晶面板至少两个不同显示区域 的至少部分像素电压再经过补偿。
需要说明的是，先调整公共电压的原因在于整个液晶面板共用一个公共电压，而且公共电压的变化会导致所有像素电压发生变化，如果补偿像素电压后再调整公共电压，则会导致已经补偿好的像素电压又发生了变化，如此，会增加时间成本，而先调整公共电压，再对像素电压进行补偿，可减少确定公共电压和像素电压的时间成本，而且公共电压的值的大小对于有经验的人员而言，基本是一个明确的值，或者在某个明确的范围内，因此公共电压更易于确定。
可选的是，液晶面板至少两个不同显示区域的至少部分像素电压经过补偿包括将液晶面板至少两个不同显示区域的至少部分像素分成不同的多个显示区域进行补偿，如此，无需将液晶面板至少两个不同显示区域的至少部分像素电压逐个调整为不同的值，可一次性将多个像素的像素电压调整为基本同样的值，提高效率。
S102，输出公共电压和像素电压对灰阶电压进行补偿。

可选的是，液晶面板所使用的液晶可为正性液晶或负性液晶。

DNA存储指令可以是将硬盘信息中的二进制数翻译成定制代码，然后借助标准DNA合成机器制造出相应的碱基序列，此碱基序列为多个重复片段，每一个片段携带一些索引细节，明确各自在整体序列中所处位置，将指令存储进每一个片段的4种碱基中。
用DNA硬盘存储指令保存时间可能长达数千年，而且即便某些片段遭损毁，指令也不会丢失，此外，DNA作为数字存储媒介的显著优点之一是容量大，DNA分子是一种令人难以置信的密集存储介质，例如1克DNA能够存储大约2拍字节(2PB)，相当于大约300万张CD。就读取而言，DNA存储不涉及兼容问题，而且信息读取成功率极高。
前述第一实施方式、第二实施方式和第三实施方式中对相应名词、句子含义的解释均可用于本实施方式，在此不再赘述。
