附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他实施例的附图。
图1为传统的像素正视和大角度曲线图；
图2为传统的主要像素和次要像素正视和大角度曲线图；
图3为传统的液晶分子运动示意图；
图4为一实施例中的显示面板的驱动方法的流程图；
图5为一实施例中的显示装置的框图。
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。
如图1所示，VA型液晶驱动在大视角亮度随电压快速饱和，如附图1中L20曲线所示，造成视角画质对比及色偏相较于正视画质品质恶化严重，正视亮度随电压曲线如附图1中L10曲线所示。
在VA型液晶技术中，为了解决视角色偏，将RGB各子像素划分为主像素和次像素，然后再空间上给予主像素和次像素不同的驱动电压。图2为子像素分主像素和次像素的曲线图，可以看出子像素分主像素和次像素可以有效解决视角色偏的缺陷，使得整体大视角亮度随电压变化较为接近正视，大视角亮度随电压如附图2中的L21曲线较为接近亮度随电压如附图2中L11曲面，其中L22、L23分别为主像素和次像素的曲线图。图3为RGB子像素液晶分子分别在低灰阶、中灰阶和高灰阶中像素分子的运动示意图，其中绿色子像素G液晶分子在中灰阶中主像素A和次像素B的运动如图3所示。但是这样的像素设计需要再设计金属走线或TFT组件来驱动次像素，从而造成可透光开口区牺牲，影响面板透率，直接造成背光成本的提升。
参见图4，在一实施例中，显示面板的驱动方法包括以下步骤：
步骤S110，将显示面板上的同一颜色像素划分为多组像素对，每一组像素对包括相邻的第一子像素和第二子像素。
步骤S120，将每一幅画面使用两帧图像依序显示，两帧图像包括第一帧图像和第二帧图像。
步骤S130，根据画面输入信号按预设规则获取对应每一个子像素的不相等的第一电压信号和第二电压信号，所述第一电压信号与第二电压信号交替驱动子像素的正视角混合亮度等效于画面输入信号驱动子像素的正视角亮度。
步骤S140，第一帧图像的第一子像素用第一子像素或第二子像素的第一电压信号驱动，第一帧图像的第二子像素用第一子像素或第二子像素的第二电压信号驱动。第二帧图像的第一子像素用第一子像素或第二子像素的第二电压信号驱动，第二帧图像的第二子像素用第一子像素或第二子像素的第一电压信号驱动。
上述驱动方法将第一帧图像的第一子像素和第二子像素分别用一高一低电压信号驱动，第二帧图像的第一子像素和第二子像素用对应的一低一高电压信号驱动。改善显示面板大视角折射率不匹配造成的色差缺点，尤其适用于TN、OCB、VA型液晶显示面板，该方法的工艺简单，生产良率高。
在步骤S120中，将每一幅画面使用两帧图像依序显示，两帧图像包括第一帧图像和第二帧图像。如表1所示的输入画面，用表2所示的第一帧图像和表3所示的第二帧图像依序显示。具体的，以RGB三原色显示面板为例，以红色子像素做说明，将空间上原相应图框子像素信号Ri，j分解成高电压RHi，j及低电压RLi，j图框并依序在相邻两个时序上显示高电压图框及低电压图框，高电压图框与低电压图框的合成效果等效于原图框各子像素亮度。高电压图框与低电压图框信号取代原始图框信号来达到正视亮度维持原图像信号亮度不变，侧视上视角透过时序上相邻两个时序上显示高电压图框及低电压图框，运用低电压图框视角特性相较于原图框亮度饱和现象可以改善进而使得视角色差获得改善。绿色子像素和蓝色子像素可以采用红色子像素相同的方法。但这样的驱动存在高电压图框与低电压图框的切换，人眼容易观察到闪烁的缺陷，可以提高图框的扫描频率来减少看到闪烁的缺陷，但受限于液晶面板 充电的技术瓶颈，提高图框的扫描频率会减少面板得穿透率或者牺牲生产的良率，降低产品的竞争力。

还可选地，第一帧图像的第一子像素用第二子像素第一电压信号驱动，第一帧图像的第二子像素用第二子像素第二电压信号驱动；第二帧图像的第一子像素用第一子像素第二电压信号驱动，第二帧图像的第二子像素用第一子像素的第一电压信号驱动。其中第一子像素和第二子像素可以横向相邻设置，第一子像素和第二子像素也可以纵向相邻设置。
可选地，上述实施方式中，第一电压信号小于第二电压信号可以替换第一电压信号大于第二电压信号。
上述实施方式中，第一子像素和第二子像素横向相邻设置，则进一步地，纵向相邻的两组像素对中其中一组像素对的第一子像素在第二子像素右侧，另一组像素对的第一子像素在第二子像素左侧。
上述实施方式中，第一子像素和第二子像素纵向相邻设置，则进一步地，横向相邻的两组像素对中其中一组像素对的第一子像素在第二子像素上方，另一组像素对的第一子像素在第二子像素下方。
采用上述实施方式除了解决了单纯单一图框均为高电压，另一图框单纯为低电压切换造成的闪烁缺陷问题，将原图框分成连续两图框输出，输出的各图框内子像素排列已经存在高低电压穿插的子像素排列，连续图框的同一子像素位置依序为高低电压输出或低高电压输出。同一图框不同位置存在高低电压排列使得连续的图框输出间的亮度差异减小，减轻两图框如果同为高电压图框与低电压图框切换的闪烁缺陷。
此外，由于原图框子像素信号必须由高电压及低电压子像素取代才能有色偏改善效果，同一图框内显示高电压及低电压子像素信息势必牺牲原图框信息解析度，通过上述实施方式中的高电压及低电压子像素排列及时序驱动方式可以维持原图像解析度相对于人眼观察不受影响。
可选地，每一组像素对的第一子像素和第二子像素可以横向相邻设置，如表5和表6所示。也可以纵向相邻设置，如表7和表8所示。
可选地，显示面板包括红色像素、绿色像素和蓝色像素，将显示面板上的红色像素划分为多组红色像素对、绿色像素划分为多组绿色像素对、蓝色像素划分为多组蓝色像素对。
进一步地，显示面板包括红色像素、绿色像素、蓝色像素和黄色像素，将显示面板上的红色像素划分为多组红色像素对、绿色像素划分为多组绿色像素对、蓝色像素划分为多组蓝色像素对、黄色像素划分为多组黄色像素对。
该显示面板的驱动方法可以改善显示面板大视角折射率不匹配造成的色偏或者色差的缺点。
显示面板可以为TN(TwistedNematic，扭曲向列)、OCB(OpticallyCompensatedBirefringence，光学补偿弯曲排列)、VA(Vertical Alignment，垂直配向)型液晶显示面板，但并不限于此。该显示面板可以为RGB三原色面板、RGBW四色面板或者RGBY四色面板，但并不限于此。其中，显示面板还可以是OLED显示面板、QLED显示面板、曲面显示面板或其他显示面板。该驱动方法同样适用于显示面板为曲面面板时的情形。
