【具体实施方式】
为使本领域的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例对本发明所提供的一种显示面板的驱动方法、驱动装置以及显示设备做进一步详细描述。在附图中，相同的标号在整个说明书和附图中用来表示相同的步骤或模块。
显示面板的白平衡是显示面板中红、绿、蓝三种基色光混合生产白色精确度的一项指标。显示面板通过控制三种基色光之间亮度比例而呈现出不同的颜色，因此，评价显示面板的在不同观看角度下色偏问题可以定义为评价显示面板在不同观看角度下三种基色光之间亮度比例的差异问题。
显示面板中，三种基色光的透过率均可以参照如下公式：
Figure PCTCN2017000034-appb-000001
公式中
Figure PCTCN2017000034-appb-000002
为液晶分子的方位角，Δnd为透过率变化因子，其中，Δn为液晶分子的双折射特性造成的正常光与非常光的折射率之差，d为盒间隙，λ为入射至液晶分子的光的波长。VA显示模式的液晶分子的方位角
Figure PCTCN2017000034-appb-000003
为固定值，但在不同观看角度下对应的透过率变化因子Δnd不同，因此，在不同观看角度下红光、绿光以及蓝光的透过率均会发生变化。
参阅图1，图1是显示面板30的结构示意图。如图1所示，在显示面板30的上基板32和下基板31之间填充液晶分子，在其上基板32靠近下基板31的一侧或者下基板31靠近上基板32的一侧设置有彩色滤光层。彩色滤光层包含有顺序排列的红色色阻R、绿色色阻G和蓝色色阻B，在整个显示面板30上的盒间隙d的厚度是一致的。
当位于A点的用户观看显示面板30时，用户相对于显示面板30的中心区域和边缘区域的观看角度发生了变化，且变化量相同，此时，三种基色光的透过率变化因子Δnd均减小，且透过率变化因子的变化量相同。假设此时红光、绿光以及蓝光的透过率变化量分别为ΔTr、ΔTg以及ΔTb，由于红光、绿光以及蓝光之间的波长关系为λr＞λg＞λb，根据上述透过率公式可知三种基色光之间的透过率变化量之间的关系为ΔTr＜ΔTg＜ΔTb。因此，从显示面板30的中心区域至边缘区域，红光的透过率变化量最小，在显示面板30边缘区域红光的亮度最高，进而导致用户观看时，显示面板30的中心区域的白平衡情况与边缘区域的白平衡情况存在差异。但现有技术中只是采用了用户正视显示面板30时所需的白平衡驱动电压对显示面板30进行白平衡的调节，不能改善显示面板30的中心区域的白平衡情况与边缘区域的白平衡情况存在差异的问题，导致A点的用户观看显示面板30时，边缘区域较中心区域色彩偏红，存在严重的色偏问题。
参阅图2，图2是本发明显示面板的驱动方法第一实施例的流程示意图。如图2所示，该驱动方法第一实施例包括如下步骤：
S11、将显示面板划分为多个区域。
本实施例中的显示面板为会由观看角度引起的色偏的显示面板。
本实施例中按照显示面板的尺寸，从显示面板的中心至边缘将显示面板划分为多个区域。对显示面板划分的区域数量不做具体限定，若需要更细节的对显示面板进行分区域调节白平衡，相应的可以划分出较多的区域。此外，由于用户处于显示面板的中间位置观看时，越往显示面板的边缘，色偏越严重，因此对显示面板划分区域时还可以将显示面板的中心部分划分的区域数量较少，边缘部分划分的区域数量较多。
S12、根据多个区域与用户的观看角度之间的关系，分别对多个区域调节白平衡。
用户相对于多个区域中的每个区域具有相应的观看角度，根据用户对于每个区域的观看角度分别对每个区域调节白平衡。
进一步的，如图3所示，步骤S12包括以下步骤：
S121、确定用户分别对多个区域的观看角度。
由于用户对于显示面板的多个区域的观看角度是存在差异，在根据用户的观看角度对显示面板进行分区域调节白平衡的前提即是要确定用户相对于多个区域的观看角度。
本实施例中，确定用户分别对多个区域的观看角度的方法具体如下：
从多个区域中确定一参考区域，参考区域的观看角度为设定角度值；根据参考区域与多个区域中其他区域之间的位置关系，确定其他区域的观看角度。
将显示面板的多个区域中的一个区域作为参考区域，用户相对于该参考区域的观看角度是设定角度值，即用户相对于参考区域的观看角度是已经设定好的已知角度值。可选的，将用户的观看角度为0度的区域作为参考区域，即将用户正视的区域作为参考区域。
由于用户观看的位置不同，则相应的参考区域也不相同。本实施中确定参考区域可以采用获取用户选择的显示模式，根据被选择的显示模式来确定参考区域。即预设若干个显示模式，将每个显示模式配置相应的参考区域，当通过用户选择确定了显示模式时，相应的参考区域也随之确定。为了避免选择不同显示模式时出现参考区域重叠的情况，可选的，不同的显示模式配置的参考区域也不同，即显示模式与参考区域之间是一一对应的关系，此时当显示模式确定时，相应的参考区域也唯一确定。
此外参考区域的还确定还可以为将显示面板的多个区域中离用户位置最近的区域设置为参考区域。由于在用户观看显示面板时，显示面板上与用户位置距离最近的位置一般即为用户正视的区域。因此，本实施例还可以通过感应设备获取用户位置，将多个区域中与用户位置距离最近的区域作为参考区域。
确定参考区域之后，即可确定多个区域中其他区域与参考区域之间的位置关系，即可随之确定用户相对于其他区域的观看角度。本实施例确定其他区域的观看角度具体为：在确定参考区域的中心线上设置一虚拟观看位置，其他区域的中心点到虚拟观看位置之间的连线与中心线之间的夹角即为其他区域的观看角度。
对上述确定用户分别对多个区域的观看角度的过程进行举例说明，图4所示，将显示面板30划分为5个区域，并将该5个区域标记为区域1至区域5。假设B点为用户位置，通过感应设备获取该用户位置后通过计算得到区域3相对于用户位置B的距离最近，因此将区域3确定为此时的参考区域。在区域3的中心线a上设置一虚拟观看位置C，区域3两边的其他区域的中心点到虚拟观看位置C的连线与中心线a之间的夹角即为区域3两边其他区域的观看角度，如图4所示，区域1至区域5的观看角度分别为θ1、θ2、0度、θ4以及θ5。可以理解的是，用户位置A与虚拟观看位置B不一定重叠，当用户位置A处于区域3的范围内是，均认为用户相对于区域3的观看角度为0度。
S122、从预设白平衡参考表格中，查找出多个区域的观看角度分别所需的白平衡驱动电压，并采用对应查找出的白平衡驱动电压分别调整多个区域的白平衡。
预设白平衡参考表格，用于存储预设的观看角度与所需的白平衡电压之间的对应关系，若知晓观看角度，即可从预设白平衡参考表格中查找该观看角度所需的白平衡驱动电压。
通过步骤S121确定用户分别对多个区域的观看角度后，根据确定的观看角度从预设白平衡参考表格中查找多个区域的观看角度所需的白平衡驱动电压。采用查找到的白平衡驱动电压分别对显示面板的多个区域调节白平衡。进而实现每个区域的白平衡情况与用户的观看角度对应，改善用户不同观看角度下显示面板的色偏问题，提高显示面板的显示质量的目的。
参阅图5，图5是本发明显示面板的驱动方法第二实施例的流程示意图。如图5所示，本实施例包括如下步骤：
S21、将显示面板划分为多个区域。
该步骤与图1所示的步骤S11相同，此处不再赘述。
S22、将多个区域中最侧边区域分别与剩余区域组成多组区域组合，并计算每个区域组合中的两个区域的中间位置分别与设定观看位置的连线之间的夹角，以作为多个测试观看角度。
该步骤用于确定多个测试观看角度，以便为角度值与多个测试观看角度的角度值相同的多个观看角度配置最佳的白平衡驱动电压。为了尽可能多的设置测试观看角度，将多个区域中最侧边区域分别与剩余区域组成多组区域组合。即多个区域中最侧边的区域分别与剩余区域两两组合，形成多个区域组合。在最侧边区域的中心线上设置一观看位置，剩余区域的中间位置与该观看位置的连线与该中心线之间的夹角即作为测试观看角度。
S23、在多个测试观看角度下，利用不同白平衡驱动电压驱动显示面板，以获取不同测试观看角度下使用不同白平衡驱动电压驱动显示面板得到的白平衡情况。
通过步骤S22确定了多个测试观看角度，则在这些测试观看角度下利用不同的白平衡驱动电压对显示面板进行驱动，进而得到每个测试观看角度下使用不同白平衡驱动电压进行驱动时的白平衡情况。由于不同观看角度下，显示面板不同区域的白平衡存在具体的差异，因此在得到每个测试观看角度下使用不同白平衡驱动电压进行驱动时的白平衡情况时，是对显示面板上的某一个位置处的白平衡情况进行获取的。具体的，在显示面板上设置一观察位置，在步骤S22得到的多个测试观看角度下利用不同的白平衡驱动电压对显示面板进行驱动，进而得到在每个测试观看角度下使用不同白平衡驱动电压进行驱动时，观察位置的白平衡情况。本实施例对白平衡情况的获取手段不做限定，可以通过技术人员观察得到，可以通过检测设置对显示面板的显示画面进行分析得到。
对步骤S22和步骤S23的过程进行举例说明：如图6a所示，显示面板30被划分为区域1至区域5，其中区域1和区域5均最侧边区域，其中选择区域1作为与剩余区域进行组合的区域(也可以选择区域5)，则区域1与区域2、区 域1与区域3...如此类推，组成四组区域组合。在区域1的中心线上设置一观看位置D，分别将区域2至区域5的中间位置与观看位置D的连线与区域1的中心线的夹角作为测试观看角度，则此时设置的测试观看角度分别为0度、α1、α2、α3和α4。
如图6b所示，将显示面板30的其中一个区域的中心位置设置为观察位置E，在步骤S22中得到的多个测试观看角度0、α1、α2、α3和α4下，利用不同的白平衡驱动电压对显示面板30进行驱动，进而获得不同的测试观看角度下使用不同的白平衡驱动电压驱动显示面板30时，观察位置E所在的区域的白平衡情况。
S24、选取每个测试观看角度观测到的最佳白平衡情况对应的白平衡驱动电压设置作为测试观看角度所需的白平衡驱动电压。
根据步骤S23得到的不同测试观看角度下采用不同的白平衡驱动电压驱动显示面板得到的白平衡情况，将在每个测试观看角度下得到的最佳白平衡情况对应的白平衡驱动电压设置作为该测试观看角度所需的白平衡驱动电压，进而得到角度值与多个测试观看角度的角度值相同的多个观看角度所需的白平衡驱动电压。进一步的，根据该步骤得到的观看角度与所需的白平衡驱动电压建立预设白平衡参考表格。
S25、根据多个区域与用户的观看角度之间的关系，分别对多个区域调节白平衡。
该步骤与图2至图3所示的步骤S12相同，此处不再赘述。
参阅图7，图7是本发明显示面板的驱动装置第一实施例的功能模块图。如图7所示，本实施例的驱动装置10包括：处理器11和存储器12，处理器11与存储器12耦接，处理器11连接显示面板20。

此外，处理器11还用于将所述多个区域中最侧边区域分别与剩余区域组成多组区域组合，并计算每个区域组合中的两个区域的中间位置分别与设定观看位置的连线之间的夹角，以作为多个测试观看角度。在所述多个测试观看角度下，利用不同白平衡驱动电压驱动所述显示面板，以获取不同测试观看角度下使用不同白平衡驱动电压驱动所述显示面板得到的白平衡情况。选取每个测试观看角度观测到的最佳白平衡情况对应的白平衡驱动电压设置作为所述测试观看角度所需的白平衡驱动电压。进而处理器11建立用于存储多个观看角度与所需的白平衡驱动电压之间关系的预设白平衡参考表格，并将预设白平衡参考表格存储在存储器12中。
进一步的，如图8所示，本实施例的驱动装置还包括感应器13，感应器13与处理器11耦接。
感应器13用于获取用户选择的显示模式，或获取用户位置。
处理器11还用于：通过感应器13获取的用户选择的显示模式，根据显示模式确定对应参考区域，其中，不同的显示模式配置有对应的参考区域；或通过感应器13获取的用户位置，将多个区域中与用户位置距离最近的区域作为参考区域。
参阅图9，图9是本发明显示设备一实施例的结构示意图。如图9所示，本实施例的显示设备包括显示面板92和用于驱动显示面板92的驱动装置91，显示面板92与驱动装置91耦接。
驱动装置91用于：将显示面板92划分为多个区域；根据多个区域与用户的观看角度之间的关系，分别对多个区域调节白平衡。
