技术领域
本申请涉及显示技术领域，尤其涉及一种显示面板的电荷分享电路、方法和显示面板。
背景技术
应当理解的是，这里的陈述仅提供与本申请有关的背景信息，而不必然地构成现有技术。
薄膜晶体管液晶显示装置(Thin Film Transistor Liquid Crystal Display，TFT-LCD)是平板显示的主要品种之一，已经成为了电子产品、视讯产品中重要的显示平台。薄膜晶体管液晶显示器主要驱动原理是系统主板将红绿蓝色阻显示的压缩信号、控制信号及电源通过线材与电路板上的连接端相连接，数据经过电路板上的时序控制器(Timing Controller，TCON)芯片处理后，经电路板板，通过源级薄膜驱动芯片(Source-Chip on Film,S-COF)和栅极薄膜驱动芯片(Gate-Chip on Film,G-COF)与显示区连接，从而使得液晶显示装置获得所需的电源和信号。因为液晶的材料特性，长时间作用于液晶上同样的电压会导致液晶极化，造成显示异常。所以薄膜晶体管液晶显示装置显示过程中需要基准电压，然后将高于基准电压的电压值定义为正极性，低于基准电压的电压值定义为负极性。显示过程中，作用于液晶上的电压每一帧会从正极性与负极性之间切换，以避免液晶极化。
将像素电极上的电压从正极性切换为负极性的过程中，会造成充电不足，即在有限的充电时间内无法将像素电极上的电压切换至目标电压。

下面参考附图和可选的实施例对本申请作进一步说明。
如图2所示，本申请实施例公布了一种显示面板100，所述显示面板100包括以下任意所述的电荷分享电路200，以及扇出区110和源极驱动芯片130，所述电荷分享电路200设置在所述扇出区110中。避免增大显示面板100的尺寸，从而提升显示面板100的品质；显 示面板的所述像素电极有不同的极性驱动模式，如常见的有相邻列极性反转的模式(即：一行像素中相邻四个像素的极性分别为+-+-)和相邻两列极性反转的模式(即：一行像素中相邻八个像素的极性分别为++--++--)；当然，所述电荷分享电路200不局限于扇出区110，只要设置在显示面板的非显示区均可，甚至可以集成在所述源极驱动芯片130内，在显示区外控制显示区内进行电荷分享，制程简单，不占用显示区内布线面积，相对于显示区内的精度要求低，工艺好操作。
如图3至图5所示，所述显示面板包括像素电极210，所述像素电极210有不同的极性驱动模式；扫描线230；给像素电极210充电的数据线220；所述电荷分享电路200包括n组共享子电路240，n≥1。以此方式控制对应像素电极的充电，在提升产品显示效果的同时降低产品的成本。
每组所述共享子电路240对应不同的像素电极210极性驱动模式进行工作，以n＝2时，以相邻的四根数据线220为一个单位示例：第一组所述共享子电路240包含有两个所述控制元件241；所述共享子电路240连接相邻的两根所述数据线220，其中第一个控制元件241连接至第一根数据线221和第二根数据线222之间，第二个控制元件241连接至第三根数据线223和第四根数据线224之间；第一组共享子电路对应的是相邻列极性反转的模式(即：一行像素中相邻四个像素的极性分别为+-+-)；第二组所述共享子电路240也包含有两个所述控制元件241；所述共享子电路240的每个所述控制元件241连接到间隔设置的两条所述数据线220上，其中第一控制元件241连接至第一根数据线221和第三根数据线223之间，第二个控制元件241连接至第二根数据线222和第四根数据线224之间。第二组共享子电路240对应的是相邻两列极性反转的模式(即：一行像素中相邻八个像素的极性分别为++--++--)；具体的共享子电路240为两组，分别根据检测的极性驱动模式来选择控制元件241，不同根将数据线220导通，通过连接的不同控制线，以此来中和数据线220之间的电荷，进行分享电荷，使得显示面板的数据线220之间的对应的像素电极210充电更节能。
在一实施例中，具体的，每组所述共享子电路240包括多个控制元件241，一个所述控制元件241连接于两条数据线220上，每条数据线220仅与每组的共享子电路240的一个所述控制元件241连接；在同一时间内，仅有一组所述共享子电路240工作；在两条数据线220之间设置一个控制元件241，在两条数据线220要发生极性反转的时候，控制元件241将两条数据线220连通，对两条数据线220连接的像素电极210的电压进行共享，在像素电极210开始充电前，先将像素电极210上的电荷中和至基准电压，再由基准电压开始向目标电压进行充电，保证像素电极210的充电量达到要求，且一个控制元件241即可将两根数据线220导通，不仅节省制程成本和物料成本，而且还可以使得两条数据线220之间进行电荷分享，进而提升显示面板100的显示效果。
在一实施例中，具体的，电荷分享电路200包括时序控制器260，每个所述控制元件241包括n个控制开关242，n与所述共享子电路240的组数n对应，每个所述控制开关242连接不同的控制线250，所述控制线250连接于所述时序控制器260上。每个控制开关242通过单独连接不同的控制线250到显示面板100内的时序控制器260中来单独控制控制开关242的开启和关闭，从而控制对应组的所述共享子电路240工作，其余组的所述共享子电路240不工作，保证工作的共享子电路240为两个要发生电极反转的数据线220之间的那一组，保证像素电极210的充电量达到要求，将像素电极中210和至所需电压，提升充电效率，进而提升显示面板100的显示效果。
当然，所述控制线250也可以连接到额外设置的控制器上，通过额外设置的控制器与显示面板100内的时序控制器260配合来控制控制开关242的开启或关闭。这样节省了显示面板100内的时序控制器260的接口占用，减小布设面积。
具体的，以两组共享子电路240为例，所述控制开关242为MOS管，所述MOS管包括P型MOS管243和N型MOS管244，每个控制元件241包括两个MOS管，所述第一组共享子电路240中每个控制元件241包括两个控制逻辑相同的MOS管，即两个P型MOS管243或两个N型MOS管244，所述第二组共享子电路240中每个控制元件241包括两个控制逻辑不同的MOS管，即一个P型MOS管243和一个N型MOS管244。
如图3所示，更具体的，M4、M6为P型MOS管243，当控制线250的信号为高电压时，P型MOS管243关闭，当控制线250的信号为低电压时，P型MOS管243开启；M1、M2、M3、M5、M7、M8为N型MOS管244，当控制线250的信号为高电压时，N型MOS管244开启，当控制线250的信号为低电压时，N型MOS管244关闭；A、B为显示面板100上的时序控制器260输出的控制信号；M1的一端与第n条数据线220连接，M1的另一端与M2的一端连接，M2的另一端与第n+1条数据线220连接，M7的一端与第n+2条数据线220连接，M7的另一端与M8的一端连接，M8的另一端与第n+3条数据线220连接；M3的一端与第n条数据线220连接，M3的另一端与M4的一端连接，M4另一端与第n+2条数据线220连接，M5的一端与第n+1条数据线220连接，M5的另一端与M6的一端连接，M6的另一端与第n+3条数据线220连接。
每组所述共享子电路240对应不同的像素电极210极性驱动模式进行工作，若所述显示面板的当前的极性驱动模式为相邻列极性反转的模式，以图3中第n条扫描线230为例进行说明，若前一帧画面的第n条扫描线230对应的像素电极R1、B1为正极性，G1、R2为负极性，当前帧的像素电极R1、B1目标电压为负极性，G1、R2的目标电压为正极性的时候，则需要在数据线220输出前进行相邻列的电荷分享；此时A的信号为高电压，B的信号为高电压，即M1、M2、M3、M5、M7、M8开启，M4、M6关闭。此时第n条数据线220与第 n+1条数据线220相连，第n+2条数据线220与第n+3条数据线220相连，进行电荷分享。
若所述显示面板的当前的极性驱动模式为相邻两列极性反转的模式，以图3中第n+条扫描线230为例进行说明，若前一帧画面的第n+1条扫描线230对应的像素电极R3、G3为正极性，B3、R4为负极性，当前帧的像素电极R3、G3目标电压为负极性，B3、R4的目标电压为正极性的时候，则需要在数据线220输出前进行隔列的电荷分享。此时A的信号为高电压，B的信号为低电压，即M1、M3、M4、M5、M6、M7开启，M2、M8关闭。此时第n条数据线220与第n+2条数据线220相连，第n+1条数据线220与第n+3条数据线220相连，进行电荷分享。
通常一个显示面板的所有行的极性驱动模式是相同的，本申请可以根据不同的极性驱动模式，选择不同组的共享子电路的控制元件的导通。在上述两种极性驱动模式中，在数据线220输出前把要发生极性反转的两条数据线220接通，将像素电极210的电压先中和至基准电压，数据线220输出后再充电至目标电压，提升充电效率，保证像素电极210的充电量达到要求，提升显示面板100的显示效果。但本申请的电荷分享电路200架构的设置也可以支持不同行极性驱动模式是不同的显示面板，可以实时根据极性驱动模式的判断，在显示面板的驱动过程中，动态选择不同组的共享子电路的控制元件的导通，适用范围广，实用性高；当然，以此规律得出的方式也是可以的。
在不需要进行电荷分享时，则A的信号为低电压，则M1、M3、M5、M7关闭，各数据线220之间的控制元件241均断开。
如图4所示，在一实施例中，在两组共享子电路240中，每组共享子电路240中的每个控制元件241只有一个MOS管；两组共享子电路240中的MOS管为相反的控制逻辑，即其中一组的为P型MOS管243，另一组为N型MOS管244，连接于一条相同的控制线250上，连接线输出的两种逻辑信号分别控制对应的MOS管开启，其中一组共享子电路240工作，另一组共享子电路240关闭；当控制线250断开的时候，两种MOS管都关闭，各数据线220之间的控制元件241均断开。此方式可以节省MOS管的数量和控制线250，降低产品的成本。
如图5所示，在一实施例中，与上述实施方式不同的是：在两组共享子电路240中，第一组共享子电路240中的有一个控制元件241，对应也只有一个N型MOS管；第二组共享子电路240中的有两个控制元件241，对应两个逻辑相反的MOS管，一个P型MOS管243和一个N型MOS管244；连接于一条相同的控制线250上，连接线输出的两种逻辑信号分别控制对应的MOS管开启，其中一组共享子电路240工作，另一组共享子电路240关闭；当控制线250断开的时候，两种MOS管都关闭，各数据线220之间的控制元件241均断开，对每个MOS管单独控制，控制精度高，响应速度快，更快速的进行电荷分享，中和至所需 要的电压，进而使得显示面板的显示效果的同时降低产品的成本。
如图6所示，本申请实施例公布了一种显示面板的电荷分享方法，包括：
S1：检测像素电极极性驱动模式；
S2：选择共享子电路；
S3：在下一帧画面输出前驱动所述共享子电路的控制元件导通；
其中，共享子电路有n组，n≥1；每种极性驱动模式对应的共享子电路的控制元件连接两条相反极性的数据线；且每条所述数据线仅与每组所述共享子电路的一个所述控制元件连接；在同一时间内，仅有一组所述共享子电路工作。
如图7所示，在一实施例中，检测所述像素电极的极性驱动模式包括步骤：
S11:检测极性驱动模式为相邻列极性反转的模式(即：+-+-)，则选择相邻列的数据线的共享子电路，在下一帧画面输出前驱动所述共享子电路的控制元件导通；
S12:检测极性驱动模式为相邻两列极性反转的模式(即：++--++--)，则选择对应间隔列的数据线的共享子电路，在下一帧画面输出前驱动所述共享子电路的控制元件导通。
如图8所示，在一实施例中，所述选择共享子电路的步骤包括：
S21:判断数据线的极性，
S22:选择连接相反极性的数据线的共享子电路。
需要说明的是，本方案中涉及到的各步骤的限定，在不影响具体方案实施的前提下，并不认定为对步骤先后顺序做出限定，写在前面的步骤可以是在先执行的，也可以是在后执行的，甚至也可以是同时执行的，只要能实施本方案，都应当视为属于本申请的保护范围。
以上内容是结合具体的可选的实施方式对本申请所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
