针对现有显示器存在驱动电路异常的问题，本申请提供一种显示面板可以缓解这个问题。
在一种实施例中，如图1至图4所示，本申请提供的显示面板包括:
显示驱动电路10，包括阵列设置的子像素驱动电路P11至Pnn,子像素驱动电路用于向阵列设置的子像素输出驱动信号；
修复驱动电路20，用于在显示驱动电路10需要补偿时，对子像素提供驱动信号；
修复开关电路30，连接修复驱动电路20的信号输出端和显示驱动电路10的信号输出端，用于在子像素驱动电路需要补偿时，导通修复驱动电路20的信号输出端和待补偿子像素驱动电路的信号输出端；
感应电路（未在图中画出），用于感应显示面板的待补偿子像素点。
本申请提供一种显示面板及显示装置，该显示面板包括显示驱动电路、修复驱动电路、修复开关电路、以及感应电路，通过在显示面板的电路中添加修复驱动电路、修复开关电路以及感应电路，在显示面板的子像素驱动电路需要补偿时，感应电路感应待补偿子像素点，待补偿子像素点所对应的修复开关电路导通，修复驱动电路向待补偿子像素输出相应的驱动信号，实现了对异常像素点自动化、高效快捷的修复，缓解了现有显示器存在驱动电路异常的问题。
在一种实施例中，如图1所示，修复驱动电路20包括子修复驱动电路Pr11至Prn1，修复驱动电路20相对于子像素驱动电路呈单列设置，即一行子像素电路对应一个子修复驱动电路。同列设置的子修复驱动电路或子像素驱动电路，通过同一条数据信号线电连接数据驱动集成电路（Date Driver IC），同行设置的子修复驱动电路和子像素驱动电路，通过同一条扫描信号线电连接扫描驱动集成电路（Scan Driver IC）。修复开关电路30相对于子像素驱动电路一一对应设置，修复开关电路30内的开关晶体管的栅极与数据驱动集成电路电连接，且位于同一列的开关晶体管电连接同一条数据信号线，子像素驱动电路的输出端通过对应的修复开关电路电连接同行设置的子修复驱动电路的输出端。
扫描驱动集成电路又被称为行驱动集成电路或栅极驱动集成电路，其作用为实现薄膜晶体管阵列逐行开启，并在控制信号的作用下与数据驱动集成电路配合，实现开启行的数据信号输入到相应的像素中去。
数据驱动集成电路又被称为源驱动集成电路，它的主要作用是接收前端时序控制器提供的数字视频数据信号和控制信号，通过数模转换把数字信号转换成相应的模拟灰阶电压信号，输入到相应的像素中去，从而控制所述像素的发光与亮度。
在上述实施例中，位于同一行的子修复驱动电路与子像素驱动电路由同一条扫描信号线控制开启或是关闭，当子修复驱动电路所在行的子像素电路正常工作时，所述子像素驱动电路对应的修复开关电路断开，所述子修复驱动电路无法形成通路，不给子像素提供驱动信号；当子修复驱动电路所在行的子像素电路出现异常需要补偿时，所述子像素驱动电路对应的修复开关电路导通，所述子修复驱动电路通过异常子像素驱动电路的输出端向异常子像素输出驱动信号。
修复驱动电路向异常子像素输出的驱动信号由数据驱动集成电路控制，在同一行中，当出现异常的子像素驱动电路为单个时，修复驱动电路的输出信号便是该异常子像素对应的驱动信号；当出现异常的子像素驱动电路为多个时，修复驱动电路的输出信号便是这几个异常子像素对应的驱动信号的平均值。
在图1所示的实施例中，子修复驱动电路端未设置修复开关电路，因为修复驱动电路为单列设置，即一行子像素电路对应一个子修复驱动电路，由子像素驱动电路端的修复开关电路，即可控制该子修复驱动电路输出端与所述子像素驱动电路输出端一对一或一对多的导通，故可省去子修复驱动电路端的修复开关电路。当然，也可以通过在修复驱动电路端设置修复开关电路，由所述修复开关电路更进一步地控制修复驱动电路端的导通与关闭。
修复开关电路30的线路连接方式不限于如1所示的设置方式，还可以是修复开关电路30内的开关晶体管的栅极与数据驱动集成电路电连接，且位于同一列的开关晶体管电连接同一条数据信号线，由数据驱动集成电路控制所述开关晶体管的导通和断开。

在另一种实施例中，如图2所示，修复驱动电路20包括子修复驱动电路Pr11至Prn2，修复驱动电路20相对于子像素驱动电路呈两列设置，即一行子像素电路对应两个子修复驱动电路。同列设置的子修复驱动电路或子像素驱动电路，通过同一条数据信号线电连接数据驱动集成电路（Date Driver IC），同行设置的子修复驱动电路和子像素驱动电路，通过同一条扫描信号线电连接扫描驱动集成电路（Scan Driver IC）。修复开关电路30相对于子像素驱动电路一一对应设置，修复开关电路30内的开关晶体管的栅极与数据驱动集成电路电连接，且位于同一列的开关晶体管电连接同一条数据信号线，子像素驱动电路的输出端通过对应的修复开关电路电连接同行设置的子修复驱动电路的输出端。
在上述实施例中，位于同一行的子修复驱动电路与子像素驱动电路由同一条扫描信号线控制开启或是关闭，当子修复驱动电路所在行的子像素电路正常工作时，所述子像素驱动电路对应的修复开关电路断开，所述子修复驱动电路无法形成通路，不给子像素提供驱动信号；当子修复驱动电路所在行的子像素电路出现异常需要补偿时，所述异常子像素驱动电路端和同行设置的修复驱动信号端的修复开关电路均导通，所述子修复驱动电路通过异常子像素驱动电路的输出端向异常子像素输出驱动信号。
在图2所示的实施例中，两个子修复驱动电路同时控制一行子像素驱动电路的补偿。在同一行中，当出现异常的子像素驱动电路为单个时，可由一个子修复驱动电路向异常子像素提供驱动信号；当出现异常的子像素驱动电路为多个时，可由两个子修复驱动电路向异常子像素提供驱动信号。由两列修复驱动电路同时对子像素驱动电路进行修复补偿，可相互缓解单列修复驱动电路的工作压力，同时，可以避免单列设置时，子修复驱动电路出现异常无法完成修复补偿的问题。
另外，两列修复驱动电路不限于如2所示的设置方式，也可以是由位于同一行的两个子修复驱动电路，分别控制该行中的部分子像素驱动电路的补偿，比如一列子修复驱动电路电连接位于图中左侧部分的子像素驱动电路，另一列子修复驱动电路电连接位于图中右侧部分的子像素驱动电路。这样可以实现对子像素驱动电路分批次、更精确的修复补偿。
同样的，修复开关电路30的线路连接方式也不限于如2所示的设置方式，还可以是修复开关电路30内的开关晶体管的栅极与数据驱动集成电路电连接，且位于同一列的开关晶体管电连接同一条数据信号线，由数据驱动集成电路控制所述开关晶体管的导通和断开。
在上述实施例中，修复驱动电路20可以设置在显示面板的非显示区内，也可以设置在显示面板的显示区内，还可以一列设置于显示面板的非显示区内，另一列设置在显示面板的显示区内。
在又一种实施例中，修复驱动电路20相对于子像素驱动电路呈多列设置，所述多列为大于等于三列。其工作原理与两列设置时相类似，具体可参考上述实施例，在此不再详细解释。
在一种实施例中，如图3所示，修复驱动电路20包括子修复驱动电路Pr11至Pr1n，修复驱动电路20相对于子像素驱动电路呈单行设置，即一列子像素电路对应一个子修复驱动电路。同列设置的子修复驱动电路和子像素驱动电路，通过同一条数据信号线电连接数据驱动集成电路（Date Driver IC），同行设置的子修复驱动电路或子像素驱动电路，通过同一条扫描信号线电连接扫描驱动集成电路（Scan Driver IC）。修复开关电路30相对于子像素驱动电路一一对应设置，修复开关电路30内的开关晶体管的栅极与数据驱动集成电路电连接，且位于同一列的开关晶体管电连接同一条数据信号线，子像素驱动电路的输出端通过对应的修复开关电路电连接同列设置的子修复驱动电路的输出端。
在上述实施例中，当子修复驱动电路所在列的子像素电路正常工作时，所述子像素驱动电路对应的修复开关电路断开，所述子修复驱动电路无法形成通路，不给子像素提供驱动信号；当子修复驱动电路所在列的子像素电路出现异常需要补偿时，所述子像素驱动电路对应的修复开关电路导通，所述子修复驱动电路通过异常子像素驱动电路的输出端向异常子像素输出驱动信号。
由于子修复驱动电路与同列的子像素驱动电路共用同一条数据线，即他们输入的数据信号是一样的，可以很好的保证在对相应的异常子像素电路进行补偿的时候，其补偿的驱动信号即为该像素点正常工作时所需的驱动信号。
在图3所示的实施例中，子修复驱动电路端未设置修复开关电路，同图1修复驱动电路单列设置时的原理相似，故省去了子修复驱动电路端的修复开关电路。当然，也可以通过在修复驱动电路端设置修复开关电路，由所述修复开关电路更进一步地控制修复驱动电路端的导通与关闭。
修复开关电路30的线路连接方式也不限于如3所示的设置方式，还可以是修复开关电路30内的开关晶体管的栅极与数据驱动集成电路电连接，且位于同一列的开关晶体管电连接同一条数据信号线，由数据驱动集成电路控制所述开关晶体管的导通和断开。
在上述实施例中，修复驱动电路20可以设置在显示面板的非显示区内，也可以设置在显示面板的显示区内。
在另一种实施例中，如图4所示，修复驱动电路20包括子修复驱动电路Pr11至Pr2n，修复驱动电路20相对于子像素驱动电路呈两行设置，即一列子像素电路对应两个子修复驱动电路。同列设置的子修复驱动电路和子像素驱动电路，通过同一条数据信号线电连接数据驱动集成电路（Date Driver IC），同行设置的子修复驱动电路或子像素驱动电路，通过同一条扫描信号线电连接扫描驱动集成电路（Scan Driver IC）。修复开关电路30相对于子像素驱动电路和子修复驱动电路分别一一对应设置，修复开关电路30内的开关晶体管的栅极与数据驱动集成电路电连接，且位于同一列的开关晶体管电连接同一条数据信号线，子像素驱动电路的输出端通过对应的修复开关电路电连接同行设置的子修复驱动电路的输出端。
在上述实施例中，当子修复驱动电路所在列的子像素电路正常工作时，所述子像素驱动电路对应的修复开关电路断开，所述子修复驱动电路无法形成通路，不给子像素提供驱动信号；当子修复驱动电路所在列的子像素电路出现异常需要补偿时，所述子像素驱动电路对应的修复开关电路导通，所述子修复驱动电路通过异常子像素驱动电路的输出端向异常子像素输出驱动信号。
在图4所示的实施例中，两个子修复驱动电路同时控制一列子像素驱动电路的补偿。由两行修复驱动电路同时对子像素驱动电路进行修复补偿，可相互缓解单行修复驱动电路的工作压力，同时，可以避免单行设置时，子修复驱动电路出现异常无法完成修复补偿的问题。
修复开关电路30的线路连接方式也不限于如2所示的设置方式，还可以是修复开关电路30内的开关晶体管的栅极与数据驱动集成电路电连接，且位于同一列的开关晶体管电连接同一条数据信号线，由数据驱动集成电路控制所述开关晶体管的导通和断开。
在上述实施例中，修复驱动电路20可以设置在显示面板的非显示区内，也可以设置在显示面板的显示区内，还可以一行设置于显示面板的非显示区内，另一行设置在显示面板的显示区内。
在又一种实施例中，修复驱动电路20相对于子像素驱动电路呈多行设置，所述多行为大于等于三行。其工作原理与两行设置时相类似，具体可参考上述实施例，在此不再详细解释。
在一种实施例中，修复驱动电路20与子像素驱动电路一一对应设置。其工作原理与多行、多列设置相似，具体可参考上述实施例，在此不再详细解释。
显示驱动电路10、修复驱动电路20、修复开关电路30内的主要部分都是薄膜晶体管，薄膜晶体管又分为P型晶体管和N型晶体管。修复驱动电路20、修复开关电路30内薄膜晶体管的设置不同，显示面板在修复补偿工作时的电压也不同。
在一种实施例中，修复驱动电路20内的修复晶体管为P型晶体管，修复开关电路内的开关晶体管为P型晶体管。当感应电路感应到异常子像素带点时，待补偿子像素点对应的修复晶体管的扫描信号电压和数据信号电压均置于低电位，待补偿子像素点对应的开关晶体管的栅极至于低电位。
在另一种实施例中，修复驱动电路20内的修复晶体管为P型晶体管，修复开关电路内的开关晶体管为N型晶体管。当感应电路感应到异常子像素带点时，待补偿子像素点对应的修复晶体管的扫描信号电压和数据信号电压均置于低电位，待补偿子像素点对应的开关晶体管的栅极至于高电位。
在又一种实施例中，修复驱动电路内的修复晶体管为N型晶体管，修复开关电路内的开关晶体管为N型晶体管，当感应电路感应到异常子像素带点时，待补偿子像素点对应的修复晶体管的扫描信号电压和数据信号电压均置于高电位，待补偿子像素点对应的开关晶体管的栅极至于高电位。
在还一种实施例中，修复驱动电路内的修复晶体管为N型晶体管，修复开关电路内的开关晶体管为P型晶体管，当感应电路感应到异常子像素带点时，待补偿子像素点对应的修复晶体管的扫描信号电压和数据信号电压均置于高电位，待补偿子像素点对应的所述开关晶体管的栅极至于低电位。
现结合具体实施例对本申请实施例提供的显示面板做进一步的诠释说明。以图1所示的实施例为例，图中修复驱动电路20和修复开关电路均采用P型晶体管，其工作时序图如图5所示。
当显示面板正常工作时，扫描驱动电压均置于高电位，修复驱动电路关闭。修复驱动电路的数据驱动电压D0置于高电位，不输出驱动信号。修复开关电路的数据驱动电压G1至Gn均置于高电位，修复开关电路断开；此外，修复开关电路的数据驱动电压G1至Gn均置于低电位，修复开关电路导通，但修复驱动电路关闭，也无法输出补偿驱动信号。
当感应电路感应到异常像素点P23时，将该异常像素点所在的位置以及其正常工作时所需补偿的驱动信号传输给数据驱动集成电路（Date Driver IC）和扫描驱动集成电路（Scan Driver IC）。扫描驱动集成电路驱动扫描驱动电压置于低电位，修复驱动电路导通。数据驱动集成电路驱动修复驱动电路的数据驱动电压D0置于低电位，输出驱动信号，该驱动信号为子像素P23正常工作时所需补偿的驱动信号；此外，数据驱动集成电路也可以关闭子像素P23驱动电路的驱动信号的输出，同时驱动修复驱动电路输出子像素P23正常工作时所需的驱动信号。数据驱动集成电路驱动子像素P23对应的修复开关电路的数据驱动电压G3置于低电位，该修复开关电路导通。修复驱动电路的输出端与子像素P23驱动电路的输出端导通，这样就实现了对显示面板异常子像素P23驱动信号的补偿工作。
同时，本申请实施例提供一种显示装置，包括显示面板，该显示包括:
显示驱动电路，包括阵列设置的子像素驱动电路，所述子像素驱动电路用于输出驱动信号；
修复驱动电路，用于在所述显示驱动电路需要补偿时，对所述子像素提供驱动信号；

本实施例提供是显示装置，其工作原理与上述实施例中所述的显示面板相似，具体可参照上述实施例，在此不再作图或文字详细解释。
本申请实施例提供一种显示装置，该显示装置包括显示面板，该显示面板包括显示驱动电路、修复驱动电路、修复开关电路、以及感应电路，通过在显示面板的电路中添加修复驱动电路、修复开关电路以及感应电路，在显示面板的子像素驱动电路需要补偿时，感应电路感应待补偿子像素点，待补偿子像素点所对应的修复开关电路导通，修复驱动电路向待补偿子像素输出相应的驱动信号，实现了对异常像素点自动化、高效快捷的修复，缓解了现有显示器存在驱动电路异常的问题。
