具体实施方式
为了便于理解本申请，下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳实施例。但是，本申请可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。
除非另有定义，本文所使用的所有的技术和科学术语与属于发明的技术领域的技术人员通常理解的含义相同。本文中在发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在限制本申请。本文所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
显示装置(例如液晶显示器)由于折射率与波长相关性，不同波长穿透率与相位延迟相关，呈现穿透率与波长有不同程度的表现，并且随着电压驱动变化，不同波长相位延迟亦会产生不同程度的变化影响不同波长的穿透率表现。如CIE(Commission Internationale de L′Eclairage，国际照明委员会)1976色度坐标图上，以VA模式的显示器特性来看，当电压驱动由高电压往低压变化时，明显对色彩纯度产生影响，高电压时色彩饱和度相当鲜艳，当电压往下驱动时，色彩鲜艳度下降，亦即以8比特显示器可以呈现0～255不同灰阶显示时，高灰阶明显饱和度相当鲜艳但低灰阶色彩鲜艳度下降。
进一步研究发现，如图1、图2以及图3所示，当面板的V-T曲线设计在公开版本2.2的情况下，RGB(red、green、blue，红、绿、蓝)个别的CIE1976色度变化，可以观察到R在56灰阶时侯色彩鲜艳度开始受到不同波长相位延迟比例不同的影响及GB子像素漏光的影响颜色鲜艳度下降，G在32灰阶时侯色彩鲜艳度开始受到不同波长相位延迟比例不同的影响及RB子像素漏光的影响颜色鲜艳度下降，B在60灰阶时侯色彩鲜艳度开始受到不同波长相位延迟比例不同的影响及RG子像素漏光的影响颜色鲜艳度下降。进一步研究发现，RGB各颜色色彩鲜艳度的下降亦反应在视角观察上，水平方向上观察视角60度的RGB各颜色色彩鲜艳度随灰阶变化的趋势，与正视角所观察情况相同，高电压时色彩饱和度相当鲜艳，当电压往下驱动时，色彩鲜艳度下降。
更进一步研究发现，显示设备各种代表性色系的大视角与正视视角色偏变化，可以明显发现，偏R、G、B色的色系大视角色偏情况均较其他色系来得严重，因此解决R、G、B色的色偏缺陷可以大大提升大视角的整体色偏改善。
基于上述理论，我们需要针对R、G、B色的灰阶进行调整，以显著改善显示界面色偏画质。
如图4所示，一种显示装置的驱动方法，包括步骤：
S200：选取显示界面划设的至少两个分区中的一个，记录为选择分区，选择分区包括至少两个像素单元。
显示界面预先划设有至少两个分区，每个分区中包括有至少两个像素单元。具体来说，每个分区内可以包括相同数量的像素单元，例如可以均包括i*j个像素单元。
S400：计算选择分区的纯度与色相值。
显示界面的纯度与色相值可以直接通过CIE LCH颜色空间系统表征。CIE LCH颜色空间系统它采用L表示亮度、C表示纯度值及H表示色相得柱形坐标。具体来说，如图5所示，在CIE LCH颜色空间系统中，CIE规范为R、G、B三色空间坐标的函数，分别为L＝f1(R、G、B)，C＝f2(R、G、B)，H＝f3(R、G、B)。其中H为颜色代表，由0°～360°代表不同色相颜色呈现，其中定义0°为红色，90°为黄色，180°为绿色，270°为蓝色，C为色彩纯度，代表颜色的鲜艳程度，C的范围表示为O到100，100代表色彩最为鲜艳，C的数值一定程度是显示设备显示高低电压信号的呈现。
非必要的，如图6所示，在其中一个实施例中，步骤S400包括：
S420：获取选择分区中各像素单元的RGB值；
S440：计算选择分区内各像素单元的RGB平均值；
S460：根据RGB平均值，计算选择分区的纯度与色相值。
在显示界面中，各个像素单元都有各自对应的RGB值，需要分别获取在该选择分区中像素单元的RGB值，针对获取的RGB值，计算选择分区内各 个像素单元的RGB平均值，再根据RGB平均值，以及LCH颜色空间系统中纯度与色相的计算函数，计算选择分区的纯度与色相值。更具体来说，计算选择分区的纯度与色相值的函数式具体为：
C＝f2{Ave R、AveG、Ave B}
H＝f3{Ave R、AveG、Ave B}
式中，Ave R、AveG以及Ave B分别为红色子像素单元平均值、绿色子像素单元平均值以及蓝色子像素单元平均值，f2为LCH模型中纯度C的计算函数，f3为LCH模型中色相H的计算函数。
S600：根据选择分区的纯度与色相值，调整选择分区中各像素单元的RGB初始灰阶参数，其中，灰阶参数包括灰阶值、灰阶电压值或灰阶电流值。
灰阶参数可以采用灰阶值表征，可以采用灰阶电压值表征，也可以采用灰阶电流值表征。灰阶值、灰阶电压值以及灰阶电流值三者是相互对应关系，即一个灰阶值可以准确对应一个灰阶电压值，也可以准确对应一个灰阶电流值，反之亦然。在不同的显示设备中，会采用不同的灰阶参数来进行显示控制，例如针对LCD(Liquid Crystal Display，液晶显示器)一般会选择灰阶电压值作为灰阶参数进行显示控制；而针对OLED(Organic Light-Emitting Diode，有机电激光显示)一般会选择灰阶电流值作为灰阶参数进行显示控制。因此，在步骤S600中我们可以选择灰阶值、灰阶电压值或灰阶电流值任意一个数值作为灰阶参数，以进行后续操作，需要指出的是，步骤S600选择的灰阶参数的类型与后续步骤选择的灰阶参数类型应当一致，即当步骤S600选择灰阶值作为灰阶参数时，后续处理步骤中灰阶参数亦为灰阶值。
选择分区不同的纯度与色相值对应的初始灰阶参数不同。具体来说，在LCH颜色空间系统中已经定义不同的纯度与色相值对应的初始灰阶参数，其划分有6个区间值，其对应的具体数值如下：
灰阶参数为灰阶值
当0°＜H≤45°或315°＜H≤360°，且CTL1≤C≤CTH2时，像素单元的RGB初始灰阶值分别为R1、G1以及B1；
当45°＜H≤135°，且CTL3≤C≤CTH4时，像素单元的RGB初始灰阶值分别为R2、G2以及B2；
当135°＜H≤205°，且CTL5≤C≤CTH6时，像素单元的RGB初始灰阶值分别为R3、G3以及B3；
当205°＜H≤245°，且CTL7≤C≤CTH8时，像素单元的RGB初始灰阶值分别为R4、G4以及B4；
当245°＜H≤295°，且CTL9≤C≤CTH10时，像素单元的RGB初始灰阶值分别为R5、G5以及B5；
当295°＜H≤315°，且CTL11≤C≤CTH12时，像素单元的RGB初始灰阶值分别为R6、G6以及B6，其中，CTL1与CTH2、CTL3与CTH4、CTL5与CTH6、CTL7与CTH8、CTL9与CTH10以及CTL11与CTH12分别为根据预设色偏画质改善需求确定的需改善颜色范围。
灰阶参数为灰阶电压值
当0°＜H≤45°或315°＜H≤360°，且CTL1≤C≤CTH2时，像素单元的RGB初始灰阶电压值分别为VR1、VG1以及VB1；
当45°＜H≤135°，且CTL3≤C≤CTH4时，像素单元的RGB初始灰阶电压值分别为VR2、VG2以及VB2；
当135°＜H≤205°，且CTL5≤C≤CTH6时，像素单元的RGB初始灰阶电压值分别为VR3、VG3以及VB3；
当205°＜H≤245°，且CTL7≤C≤CTH8时，像素单元的RGB初始灰阶电压值分别为VR4、VG4以及VB4；
当245°＜H≤295°，且CTL9≤C≤CTH10时，像素单元的RGB初始灰阶电压值分别为VR5、VG5以及VB5；
当295°＜H≤315°，且CTL11≤C≤CTH12时，像素单元的RGB初始灰阶电压值分别为VR6、VG6以及VB6，其中，CTL1与CTH2、CTL3与CTH4、CTL5与CTH6、CTL7与CTH8、CTL9与CTH10以及CTL11与CTH12分别为根据预设色偏画质改善需求确定的需改善颜色范围。
0°＜H≤45°或315°＜H≤360°对应红色色调区间，45°＜H≤135°对应黄色色调区间、135°＜H≤205°对应绿色色调区间、205°＜H≤245°对应青色色调区间、245°＜H≤295°对应蓝色色调区间、295°＜H≤315°对应紫色色调区间。在实际应用中，以8比特位显示设备为例，其对应灰阶范围为0～255，根据三基色原理，RGB三基色对应红色，其对应灰阶为红色(255，0，0)、绿色(0，255，0)、蓝色(0，0，255)；红色+绿色＝黄色(255，255，0)、红色+蓝色＝品红(255，0，255)、绿色+蓝色＝青色(0，255，255)。
S800：获取选择分区的原输入信号，根据原输入信号以及RGB初始灰阶参数，调整原输入信号对应灰阶参数。
原输入信号中会携带有其对应灰阶信息，对应灰阶信息包括其当前对应的原灰阶参数以及原输入信号对应的终止点信号等，8比特位显示设备的输入信号灰阶值对应范围为0～255，其灰阶电压值为V0～V255，终止点信号对应灰阶值为255；10比特位显示设备的输入信号灰阶值对应范围为0～510，其灰阶电压值为V0～V510，其终止点信号对应灰阶值为510；12比特位显示设备的输入信号灰阶值对应范围为0～1020，其灰阶电压值为V0～V1020，其终止点信号对应灰阶值为1020。
若步骤S600中灰阶参数为灰阶值，则可基于原输入信号对应的灰阶值、原输入信号对应的终止点信号以及RGB初始灰阶值，调整原输入信号对应灰阶值。在其中一个实施例中，根据原输入信号以及RGB初始灰阶，调整原输入信号对应灰阶的步骤包括：步骤一：识别原输入信号对应的原灰阶值与终止点信号。以某个原输入信号X为例，分析该原输入信号X其可以获知其对应的原灰阶值，例如为2，进一步还可以识别出原输入信号X对应的终止点信号，当原输入信号X是针对8比特位显示设备时，其对应的灰阶值范围为0～255，则其终止点信号为(R255、G255、B255)。步骤二：根据原输入信号对应的原灰阶值与终止点信号以及RGB初始灰阶值，确定调整后原输入信号对应灰阶值为f{原灰阶值，γ，初始灰阶值，终止点信号}，其中γ为影响全灰阶亮度曲线变化值，f为根据初始灰阶对应亮度、终止点信号对应亮度以及 影响全灰阶亮度曲线变化值γ预设确定的函数。假定原输入信号X的原灰阶值为2、其终止点信号为(R255、G255、B255)，步骤S600确定其初始灰阶值为(R1、G1、B1)，则针对R其对应灰阶值为f{2，γ，R1，R255}；针对G其对应灰阶值为f{2，γ，G1，G255}；针对B其对应灰阶值为{2，γ，B1，B255}。其中，γ为影响全灰阶亮度曲线变化值，该数值可以基于历史经验数据直接获取。
若步骤S600中灰阶参数为灰阶电压值，则根据获取的选择分区的原输入信号，获取原输入信号的全灰阶对应灰阶电压值，根据调整后的RGB初始灰阶电压值，调整原输入信号中各灰阶对应灰阶电压值。具体来说，选择分区的原输入信号是对应全灰阶的，例如对应0～255灰阶，即RGB初始灰阶为(0，0，0)，其终止灰阶为(255，255，255)，其对应的初始灰阶值为(V0，V0，V0)，其对应的终止灰阶值为(V255，V255，V255)，步骤S600处理之后得到调整后的RGB初始灰阶电压值，以该初始灰阶电压值作为起点，调整原输入信号中各灰阶对应灰阶电压值。更进一步来说，调整后的各灰阶对应灰阶电压值中每一灰阶增加的电压值为调整前原输入信号中当前灰阶与上一灰阶之间对应灰阶电压差值，假定步骤S600，确定调整后的原输入信号RGB初始灰阶电压值为(VR1、VG1、VB1)，则调整前原输入信号1对应灰阶电压值为(V1，V1，V1)，则调整后原输入信号1对应灰阶电压值为(VR1+(V1-V0)，VG1+(V1-V0)，VB1+(V1-V0))。
若灰阶参数为灰阶电流值，则可以采用上述为灰阶电压值时类似的处理方式，直接将电压值替换为电流值即可，在此，不再赘述。
上述显示装置的驱动方法，选取显示界面划设的至少两个分区中的一个，记录为选择分区，计算选择分区的纯度与色相值，根据纯度与色相值，调整各像素单元的RGB初始灰阶参数，获取选择分区的原输入信号，根据原输入信号以及RGB初始灰阶参数，调整原输入信号对应灰阶参数。整个过程中，计算分区的各像素单元的纯度与色相值来调整该分区的RGB输入信号对应灰阶参数，可以显著改善显示界面色偏画质。
为更进一步详细解释本申请显示装置的驱动方法，下面将针对灰阶参数为灰阶值以及灰阶参数为灰阶电压值分别采用具体应用实例进行展开说明。
当灰阶参数为灰阶值时，在应用实例中，本申请显示装置的驱动方法包括以下步骤：
选取显示界面划设的至少两个分区中的一个，记录为选择分区(M*N分区)，选择分区中包括i*j个像素单元；
计算N*M区内的所有子像素单元RN*M_i，j，GN*M_i，j，BN*M_i，j(其中i，j为该N*M区内的像素单元)的平均信号Ave_RN*M_i，j，Ave_GN*M_i，j，Ave_BN*M_i， j；
计算该分区的CN*M＝f1(Ave_RN*M_i，j，Ave_GN*M_i，j，Ave_BN*M_i，j)，HN*M＝f2(Ave_RN*M_i，j，Ave_GN*M_i，j，Ave_BN*M_i，j)，LN*M＝f3(Ave_RN*Mi，j，Ave_GN*M_i，j，Ave_BN*M_i，j)；
运用计算该区间子像素所得到的CN*M以及HN*M判断R、G、B初始灰阶值，其具体判断依据如下：
当0°＜H≤45°或315°＜H≤360°，且CTL1≤C≤CTH2时，像素单元的RGB初始灰阶值分别为R1、G1以及B1；
当45°＜H≤135°，且CTL3≤C≤CTH4时，像素单元的RGB初始灰阶值分别为R2、G2以及B2；
当135°＜H≤205°，且CTL5≤C≤CTH6时，像素单元的RGB初始灰阶值分别为R3、G3以及B3；
当205°＜H≤245°，且CTL7≤C≤CTH8时，像素单元的RGB初始灰阶值分别为R4、G4以及B4；

当CN*M以及HN*M满足0°＜HN*M≤45°以及315°＜HN*M≤360°色相区间并且彩度符合CTL1≤CN*M≤CTH2区间，则R的初始灰阶定为R1，G的初始灰阶定为G1，B的初始灰阶定为B1。其中新对应各灰阶输出信号如原输入R信号为2灰阶，新对应R信号为f(2，γ，R1，R255)，该输出灰阶信号与原输入信号2，初始灰阶信号R1及终点输出信号R255以及影响全灰阶亮度曲线变化的γ值相关，新对应R信号为该4因子的对应函数，f为根据初始灰阶对应亮度、终止点信号对应亮度以及影响全灰阶亮度曲线变化值γ预设确定的函数，即根据初始灰阶信号R1对应亮度、终止点信号R255对应亮度以及全灰阶亮度曲线变化值γ确定的函数，在实际应用中，可以先基于初始灰阶信号R1对应亮度、终止点信号R255对应亮度以及全灰阶亮度曲线变化值γ确定的函数得出函数f，再针对后续计算处理中，直接使用该函数f。相应的针对G信号以及B信号也采用上述方式，在此不再赘述。
全灰阶输入信号对应的灰阶值则分配为如下表1的灰阶对应输出灰阶值表，以此类推。

需要指出的是，在上述实施例中分区并不指代特定的，即i与j的取值可以为任意值，只需满足i*j的值大于2，即分区中至少包括2个像素单元。当i与j取不同数值时，同样可以采用上述相同方式处理，在此不再赘述。
当灰阶参数为灰阶电压值时，在应用实例中，本申请显示装置的驱动方法包括以下步骤：
选取显示界面划设的至少两个分区中的一个，记录为选择分区(M*N分区)，选择分区中包括i*j个像素单元；
计算N*M区内的所有子像素单元RN*M_i，j，GN*M_i，j，BN*M_i，j(其中i，j为该N*M区内的像素单元)的平均信号Ave_RN*M_i，j，Ave_GN*M_i，j，Ave_BN*M_i， j；
计算该分区的CN*M＝f1(Ave_RN*M_i，j，Ave_GN*M_i，j，Ave_BN*M_i，j)，HN*M＝f2(Ave_RN*M_i，j，Ave_GN*M_i，j，Ave_BN*M_i，j)，LN*M＝f3(Ave_RN*M_i，j，Ave_GN*M_i，j，Ave_BN*M_i，j)。
运用计算该区间子像素所得到的CN*M以及HN*M判断R、G、B初始灰阶电压值，其具体判断依据如下：
