需要说明的是，本实施例中，第一开关管T1、第二开关管T2分别独 立选自多晶硅薄膜晶体管、非晶硅薄膜晶体管、氧化物薄膜晶体管以及有机薄膜晶体管中的一种。所采用的晶体管可以为薄膜晶体管或场效应管或其他特性的相同器件，由于采用的晶体管的源极和漏极在一定条件下是可以互换的，所以其源极、漏极从连接关系的描述上是没有区别的。在本实施例中，为区分晶体管的源极和漏极，将其中一极称为第一极，另一极称为第二极，栅极称为控制极。此外按照晶体管的特性区分，可以将晶体管分为N型和P型，以下是以晶体管为N型晶体管为例进行说明的。当采用N型晶体管时，其栅极输入高电平时，其源漏极导通。当采用P型晶体管时，其栅极输入低电平时，其源漏极导通。可以想到的是，采用P型晶体管的实现是本领域技术人员可以在不付出创造性劳动的前提下轻易想到的，因此落入本公开的保护范围内。
除非另外定义，本公开实施例所使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开实施例中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意在指出该词前面的元件或物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述的对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
本公开的实施例还提供一种显示装置，包括上述实施例的显示基板。
在一些实施方式中，所述显示装置还包括检测模块和控制模块。所述检测模块配置为根据接收到的视频信号确定待显示画面是否为灰阶画面或闪烁画面。所述控制模块配置为实现以下功能中的至少之一：在所述检测模块确定出待显示画面为灰阶画面时，控制所述补偿开启电路通过各第三信号输出端向对应的栅线写入导通信号，并控制所述电压补偿电路通过各第四信号输出端向对应的数据线写入补偿信号；在所述检测模块确定出待显示画面为闪烁画面时，控制所述补偿开启电路通过各第三信号输出 端向对应的栅线写入导通信号，并控制所述电压补偿电路通过与奇数列数据线连接的第四信号输出端分别向对应的数据线写入补偿信号，或通过与偶数列数据线连接的第四信号输出端分别向对应的数据线写入补偿信号。

本公开的实施例还提供一种显示基板的驱动方法，所述显示基板为上述实施例的显示基板，所述驱动方法包括以下步骤S01和S02。
S01、确定显示基板的待显示画面是否为灰阶画面或闪烁画面。
S02、执行以下操作中的至少之一：当显示基板的待显示画面为灰阶画面时，控制所述补偿开启电路2通过各第三信号输出端向对应的栅线写入导通信号，并控制所述电压补偿电路3通过各第四信号输出端向对应的数据线写入补偿信号；当显示基板的待显示画面为闪烁画面时，控制所述补偿开启电路2通过各第三信号输出端向对应的栅线写入导通信号，并控制所述电压补偿电路3通过与奇数列数据线连接的第四信号输出端向对应的数据线写入补偿信号或通过与偶数列数据线连接的第四信号输出端向对应的数据线写入补偿信号。
以下以显示装置实施本公开实施例的显示基板的驱动方法为例进行具体说明。
如图2所示，显示装置可通过检测模块根据接收到的一帧数据进行判别，其要显示的画面是否为灰阶画面或闪烁画面，具体地，检测模块可对比该帧数据的电压与预存的灰阶画面或闪烁画面的额定电压内是否一致，如果不一致，则判断出要显示的画面不属于灰阶画面或闪烁画面。该情况下，如图3所示，所述奇控制补偿信号线S-W-ODD、所述偶控制补偿信号线S-W-EVEN、所述补偿信号供给线S-Level、所述偶控制开启信号线G-W-L、所述奇控制开启信号线G-W-R、所述偶导通信号供给线G-L、所述奇导通供给线G-R上的信号可均为低电平，补偿开启电路2、电压补偿电路3不工作，此时显示装置正常显示。
如果判断出要显示的画面属于灰阶画面，可通过控制模块控制补偿 开启电路2通过各第三信号输出端向对应的栅线写入导通信号，并控制所述电压补偿电路3通过各第四信号输出端向对应的数据线写入补偿信号。该情况下，如图4中Blanking区间所示，所述奇控制补偿信号线S-W-ODD、所述偶控制补偿信号线S-W-EVEN、所述偶控制开启信号线G-W-L、所述奇控制开启信号线G-W-R、所述偶导通信号供给线G-L、所述奇导通供给线G-R上的信号可均为高电平，所有栅线Gate1、Gate2……选通，所述补偿信号供给线S-Level提供充电电压，所有像素单元执行显示，此充电电压的大小可根据要显示的灰阶画面的数据电压决定。图5示出了显示的灰阶画面的示意图。
如果判断出要显示的画面属于闪烁画面，可通过控制模块控制所述补偿开启电路2通过各第三信号输出端向对应的栅线写入导通信号，并控制所述电压补偿电路3通过例如与奇数列数据线连接的第四信号输出端向对应的数据线写入补偿信号。该情况下，如图6中Blanking区间所示，所述奇控制补偿信号线S-W-ODD、所述偶控制开启信号线G-W-L、所述奇控制开启信号线G-W-R、所述偶导通信号供给线G-L、所述奇导通供给线G-R上的信号可均为高电平，所述偶控制补偿信号线S-W-EVEN上的信号可为低电平，所有栅线Gate1、Gate2……选通，奇数列像素单元执行显示，偶数列像素像素单元关闭，所述补偿信号供给线S-Level提供充电电压，此充电电压大小可根据闪烁画面的数据电压决定。图7示出了显示的闪烁画面的示意图。
作为选择，如果判断出要显示的画面属于闪烁画面，也可通过控制模块控制所述补偿开启电路2通过各第三信号输出端向对应的栅线写入导通信号，并控制所述电压补偿电路3通过例如与偶数列数据线连接的第四信号输出端向对应的数据线写入补偿信号。该情况下，所述偶控制补偿信号线S-W-EVEN、所述偶控制开启信号线G-W-L、所述奇控制开启信号线G-W-R、所述偶导通信号供给线G-L、所述奇导通供给线G-R上的信号可均为高电平，所述奇控制补偿信号线S-W-ODD上的信号可为低电平，所有栅线Gate1、Gate2……选通，奇数列像素单元执行显示，偶数列像素单元关闭，所述补偿信号供给线S-Level提供充电电压，此充电电压大小可根据闪烁画面的数据电压决定。
本实施例中，通过在显示灰阶画面或闪烁画面时对相应的像素单元进行充电，弥补了由于薄膜晶体管漏电导致的像素电压降低、显示画面闪烁的问题。
可以理解的是，以上实施例仅仅是为了说明本公开的原理而采用的示例性实施例，然而本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为落入本公开的保护范围。
