Description

显示面板、显示面板的驱动方法及电子装置 技术领域
本发明涉及显示技术领域，尤其涉及一种显示面板、显示面板的驱动方法及电子装置。
 背景技术
随着显示技术的发展，液晶显示面板的分辨率及刷新频率均越来越高，分辨率为8K，刷新频率为120Hz的液晶显示面板是未来的主流。对于分辨率为8K，刷新频率为120Hz的液晶显示面板来说，其像素数量大幅增加，每一帧画面的刷新时间却大幅减少，这意味着，每一行子像素的充电时间大幅减少，若采用常规的1行子像素一条扫描线，一列子像素一条数据线的像素架构，每一个子像素的充电时间无法得到保证，从而导致充电不足，引起画面异常，同时从产品成本考虑，4畴像素结构相比于8畴像素结构具有更低的成本，与此同时4畴像素结构又存在改善大视角色偏严重的问题。
 技术问题
现有改善大视角色偏的方案是将显示面板中的多个子像素区分为高亮度和低亮度两种不同的显示状态，借由低亮度的子像素压低侧视时亮度的变化程度。显示区内低亮度状态的子像素数量越多，则色偏改善程度越佳，但是增加低亮度状态的子像素会影响显示画面的清晰程度，产生颗粒感。

 本发明的实施方式
以下各实施例的说明是参考附加的图示，用以例示本揭示可用以实施的特定实施例。本揭示所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本揭示，而非用以限制本揭示。在图中，结构相似的单元是用以相同标号表示。
下面结合附图和具体实施例对本揭示做进一步的说明：
本申请实施例提供一种显示面板、显示面板的驱动方法及电子装置，所述电子装置包括所述显示面板，所述显示面板的驱动方法用于驱动所述显示面板。
所述电子装置可以车载显示终端，例如车载显示器、行车记录仪等，所述电子装置也可以是移动终端，例如智能手机、平板电脑、笔记本电脑等，或者是可穿戴式终端，例如智能手表、智能手环、智能眼镜、增强现实设备等，所述电子装置还可以是固定终端，如台式电脑、电视等，也可以是车载显示终端，如车载显示器或行车记录仪等。
如图1所示，图1为本申请实施例提供的显示面板的结构示意图，所述显示面板100包括显示面板主体10和驱动单元20，所述驱动单元20可以为源极驱动芯片或源极驱动电路，驱动单元20连接于所述显示面板主体10并用以驱动显示面板主体10进行画面显示。
如图2所示，图2为本申请实施例提供的显示面板主体的结构示意图，所述显示面板主体10包括多个第一子像素11、多个第二子像素12和多个第三子像素13，多个第一子像素11、多个第二子像素12和多个第三子像素13在显示面板主体10的显示区内呈多行和多列分布。
需要说明的是，图2仅对显示面板主体10中各子像素的位置关系以及分布情况进行了示意图，图2中各子像素的数量并不代表实际应用中显示面板主体10中各子像素的数量。
在本申请实施例中，第一子像素11、第二子像素12和第三子像素13的颜色不限，第一子像素11、第二子像素12和第三子像素13均可以为红色子像素、绿色子像素和蓝色子像素中的任意一种。第一子像素11可以与第二子像素12或第三子像素13的颜色相同，第一子像素11也可以与第二子像素12或第三子像素13的颜色不同，此处不做限制。
进一步的，在同一帧画面中，所述驱动单元用于以第一显示灰阶和第二显示灰阶的其中之一驱动所述第一子像素进行显示，所述驱动单元还用于以所述第一显示灰阶和所述第二显示灰阶的其中另一驱动所述第二子像素进行显示。
如图3所示，图3为本申请实施例提供的显示面板的画面切换示意图，以图3中3a为例进行说明，在3a所示的当前帧画面中，驱动单元20以第一显示灰阶H’驱动第一子像素11进行显示，驱动单元20以第二显示灰阶L’驱动第二子像素12进行显示，驱动单元20以第三显示灰阶L驱动第三子像素进行显示。
第一显示灰阶H’大于或等于第三显示灰阶L，第二显示灰阶L’小于或等于第三显示灰阶L。如此，可以使得第一显示灰阶H’与第二显示灰阶L’之间的差值大于或等于第一显示灰阶H’与第三显示灰阶L之间的差值，使得具有较高灰阶值的第一显示灰阶H’的基色分量和具有较低灰阶值的第二显示灰阶L’的基色分量之间的显示亮度的差异进一步加大，以此提高各基色分量的亮度对比，从而改善显示面板在大视角下色偏严重的问题。
在由3a切换到3b所示的画面时，驱动单元20以第二显示灰阶L’驱动第一子像素11进行显示，驱动单元20以第一显示灰阶H’驱动第二子像素12进行显示，驱动单元20以第三显示灰阶L驱动第三子像素13进行显示。如此可以使不同帧画面中，第一子像素11和第二子像素12均可以交替呈现第一显示灰阶H’和第二显示灰阶L’这两种不同亮度的显示状态。在显示面板100处于较高刷新率的情况下，如90HZ或120HZ等，人眼无法感知第一子像素11和第二子像素12的明暗切换状态，如此可以减弱显示画面的颗粒感，从而提高显示画面的清晰程度。
进一步的，如图1所示，所述显示面板100还包括获取单元30和处理单元40，获取单元30连接于所述处理单元40，处理单元40连接于驱动单元20。
获取单元30用于获取第一子像素11、第二子像素12和第三子像素13各自的原始显示灰阶H，处理单元40用于根据各子像素的原始显示灰阶进行色偏补偿处理，获得所述第一显示灰阶H’、所述第二显示灰阶L’和所述第三显示灰阶L。
在本申请实施例中，所述第一显示灰阶H’和所述第二显示灰阶L’之和与所述原始显示灰阶H的比值为2:1，如此可以使第一子像素11和第二子像素12的显示亮度在混合后能够保持与以原始显示灰阶H驱动的两个子像素的亮度一致。
在本申请实施例中，所述显示面板100的bit值为8，第一显示灰阶H’、所述第二显示灰阶L’以及所述第三显示灰阶L均大于或等于0且小于或等于255。在实际应用中，所述显示面板的bit值不仅限于上述实施例中的8，也可以为6或10等，第一显示灰阶H’、所述第二显示灰阶L’以及所述第三显示灰阶L的取值范围则需要根据bit值进行调整，此处不做赘述。
进一步的，所述显示面板100具有多个重复单元14，所述重复单元14由所述第一子像素11、所述第二子像素12和所述第三子像素13构成。
在本申请实施例中，如图2所示，每一个所述重复单元14均由8个子像素构成，该8个子像素中包括2个第一子像素11、2个第二子像素12和4个第三子像素，第一子像素11与第二子像素12以及第三子像素13的数量比为1:1:2。如此，可以使得以第一显示灰阶H’、第二显示灰阶L’以及第三显示灰阶L驱动的重复单元14的显示亮度在混合后与以原始显示灰阶H驱动的重复单元14的亮度相同，以此在改善显示面板在大视角色偏的同时，还可以保证显示面板的清晰度不受影响。
在实际应用中，每一个所述重复单元14中包含的子像素的数量不仅限于上述实施例中的8个，也可以为4个、12个等4的倍数，仅需要满足重复单元14中第一子像素11与第二子像素12以及第三子像素13的数量比为1:1:2即可。
在本申请实施例中，如图2所示，所述重复单元14由相邻两列中的四行子像素构成，每一行均设置有一个第三子像素13以及与该第三子像素13相邻的第一子像素11或第二子像素12。在实际应用中，重复单元14中各子像素的排布方式不仅限于上述实施例，也可以包括但不限于将该四个第三子像素13均设置于前两行，而将第一子像素11和第二子像素12设置于后两行，两个第一子像素11可以位于同一行，也分别设置于相邻行并与第二子像素12位于同一行。
进一步的，所述驱动单元20每间隔N帧以所述第一显示灰阶H’或所述第二显示灰阶L’驱动所述第一子像素11进行显示，所述驱动单元20每间隔N帧以所述第一显示灰阶H’或所述第二显示灰阶L’驱动所述第二子像素12进行显示，其中N大于或等于1，且N为整数。
在一实施例中，当N等于1时，第一子像素11的极性每间隔一帧切换以此，第二子像素12的极性每间隔一帧切换一次。
如图4所示，图4为本申请实施例提供的第一种极性反转方式的示意图。设定本实施例中显示面板的极性反转方式为列反转，在第一帧画面F1中，重复单元14中第一列子像素的极性均为正极性（+），第二列子像素的极性均为负极性（—）；当切换到第二帧画面F2时，重复单元14中第一列子像素的极性均仍为正极性（+），第二列子像素的极性均仍为负极性（—）；当切换到第三帧画面F3时，重复单元14中第一列子像素的极性均切换为负极性（—），第二列子像素的极性均切换为正极性（+），当切换到第四帧画面F4时，重复单元14中第一列子像素的极性均仍为负极性（—），第二列子像素的极性均仍为正极性（+），以上述四帧为一个循环，如此循环往复进行极性的切换。
若N=1时，采取每一帧切换一次极性，则会使第一子像素11以第一显示灰阶H’进行显示时，第一子像素11的极性均为正极性（+），第一子像素11以第二显示灰阶L’进行显示时，第一子像素的极性均为负极性（—），第二子像素12的情况与第一子像素11的情况类似，此处不做赘述。如此，会造成显示面板出现残影等显示不良的情况。因此，当N=1时，若第一子像素11、第二子像素12以及第三子像素13的极性均采用每间隔一帧切换一次极性，可以使第一子像素11和第二子像素12在不同帧画面中以第一显示灰阶H’或第二显示灰阶L’显示时，极性均会发生改变，从而可以避免显示面板出现残影等显示不良的情况。
在一实施例中，当N大于或等于2时，相邻两帧画面中，所述第一子像素的极性不同，所述第二子像素的极性不同。
如图5所示，图5为本申请实施例提供的第二种极性反转方式的示意图，在本申请实施例中，N=2，在第一帧画面F1中，重复单元14中第一列子像素的极性均为正极性（+），第二列子像素的极性均为负极性（—）；切换到第二帧画面F2时，第一列子像素的极性均切换为负极性（—），第二列子像素的极性均切换为正极性（+），以上述两帧为一个循环，如此循环往复进行极性的切换。如此，可以使得相邻两帧中的第一子像素11若均以第一显示灰阶H’或第二显示灰阶L’进行显示时，第一子像素11的极性能够发生改变，从而可以避免显示面板出现残影等显示不良的情况。
当N取大于2且为整数的值时，显示面板100的极性反转方式与图4所示的极性反转方式相同，此处不做赘述。在实际应用中，显示面板100的极性反转方式不仅限于上述实施例中的列反转，同样也可以为行反转、点反转或帧反转等，此处不做赘述。
需要说明的是，图4和图5均仅以显示面板100中的任意一个重复单元14为例进行说明，其他重复单元14的切换方式与图4或图5中所示的重复单元14的切换方式相同，此处不做赘述。
在本申请实施例中，所述显示面板的驱动方法包括：在同一帧画面中，以第一显示灰阶H’和第二显示灰阶L’的其中之一驱动所述第一子像素11进行显示，以所述第一显示灰阶H’和所述第二显示灰阶L’的其中另一驱动所述第二子像素12进行显示；在不同帧画面中，以所述第一显示灰阶H’和所述第二显示灰阶L’交替驱动所述第一子像素11进行显示，以所述第一显示灰阶H’和所述第二显示灰阶L’交替驱动所述第二子像素12进行显示，以第三显示灰阶L驱动所述第三子像素13进行显示。
在本申请实施例提供的驱动方法中，所述第一显示灰阶H’大于或等于所述第三显示灰阶L，所述第二显示灰阶L’小于或等于所述第三显示灰阶L。
