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，下面结合附图对本发明提供的触摸显示驱动方法、驱动模块和显示装置进行详细描述。
图1为本发明实施例一提供的一种触摸显示驱动方法的流程图，如图1所示，该方法包括：
步骤101、检测是否发生触摸动作，若否，则执行步骤102；若是则执行步骤103。
本实施例中各步骤可以由驱动模块执行。
步骤102、以第一驱动模式进行显示驱动和触摸驱动，流程结束。
步骤103、以第二驱动模式进行显示驱动和触摸驱动，第一驱动模式下的驱动频率小于第二驱动模式下的驱动频率。
本实施例提供的触摸显示驱动方法的技术方案中，在未检测出发生触摸动作时以第一驱动模式进行驱动，在检测出发生触摸动作时以第二驱动模式进行驱动，第一驱动模式下的触摸驱动频率小于第二驱动模式下的触摸驱动频率，整体上降低了驱动频率，从而降低了驱动模块的功耗。
图2为本发明实施例二提供的一种触摸显示驱动方法的流程图，如图2所示，该方法包括：
步骤201、检测是否发生触摸动作，若否，则执行步骤202；若是，则执行步骤203。
本实施例中各步骤可以由驱动模块执行。优选地，驱动模块为TDDI。驱动模块可用于驱动显示面板，以使显示面板进行显示和触摸。显示面板 可包括相对设置的彩膜基板和阵列基板，阵列基板可包括衬底基板和位于衬底基板之上的栅线和数据线，栅线和数据线限定像素单元。
步骤202、在连续多个显示阶段输出触摸行的显示数据以用于显示，并在多个显示阶段之后的一个行消隐阶段输出触摸驱动信号以用于触摸，流程结束。
其中，可将全部栅线分为多个栅线组，每个栅线组包括若干条栅线，则每个栅线组为一个触摸行，换言之，一个触摸行可包括多条栅线，例如：一个阵列基板可包括12个触摸行。
本实施例中，显示数据可包括栅极驱动信号和源极驱动信号。
本实施例中，行消隐阶段为长时间行消隐(Long H-Blank，简称：LH-Blank)阶段。
优选地，本步骤中，在连续两个显示阶段输出触摸行的显示数据以用于显示，并在两个显示阶段之后的一个行消隐阶段输出触摸驱动信号以用于触摸。
图3为本发明中显示阶段和行消隐阶段的示意图，如图3所示，以显示面板包括12个触摸行为例，每个触摸行的显示阶段之后为一个行消隐阶段。第一个显示阶段中，驱动模块输出第一个触摸行的显示数据给显示面板以供显示面板进行显示；而在第一个行消隐阶段中，驱动模块不输出触摸驱动信号。第二个显示阶段中，驱动模块输出第二个触摸行的显示数据给显示面板以供显示面板进行显示；而在第二个行消隐阶段中，驱动模块输出触摸驱动信号以用于触摸，在第二个行消隐阶段若检测出触摸动作，则驱动模块对触摸产生的感测信号进行接收。以此类推，直至第十二个显示阶段和之后的第十二个行消隐阶段。图3所示的为隔行进行触摸驱动的方案，由于隔行进行触摸驱动，因此行消隐阶段的触摸驱动的频率小于显示阶段的显示驱动的频率。
步骤203、在每个显示阶段输出触摸行的显示数据以用于显示，并在该显示阶段之后的行消隐阶段输出触摸驱动信号以用于触摸。
如图3所示，第一个显示阶段中，驱动模块输出第一个触摸行的显示数据给显示面板以供显示面板进行显示；而在第一个行消隐阶段中，驱动模块输出触摸驱动信号以用于触摸，在第一个行消隐阶段若检测出触摸 动作，则驱动模块对触摸产生的感测信号进行接收。第二个显示阶段中，驱动模块输出第二个触摸行的显示数据给显示面板以供显示面板进行显示；而在第二个行消隐阶段中，驱动模块输出触摸驱动信号以用于触摸，在第二个行消隐阶段若检测出触摸动作，则驱动模块对触摸产生的感测信号进行接收。以此类推，直至第十二个显示阶段和之后的第十二个行消隐阶段。步骤203中为逐行进行触摸驱动的方案，由于逐行进行触摸驱动，因此行消隐阶段的触摸驱动的频率等于显示阶段的显示驱动的频率。
本实施例中，重复执行步骤201至步骤203，以完成对一帧画面的显示和触摸过程。而后，可继续执行对下一帧画面的显示和触摸过程。
本实施例中，驱动模块若未检测出触摸动作，则以第一驱动模式进行显示驱动和触摸驱动，此时行消隐阶段的触摸驱动的频率小于显示阶段的显示驱动的频率；驱动模块若检测出触摸动作，则以第二驱动模块进行显示驱动和触摸驱动，此时行消隐阶段的触摸驱动的频率等于显示阶段的显示驱动的频率。从上述内容可以看出，两种驱动模式下，显示阶段的显示驱动的频率是相同，而第一驱动模式下行消隐阶段的触摸驱动的频率小于第二驱动模式下行消隐阶段的触摸驱动的频率，从而第一驱动模式下的驱动频率小于第二驱动模式下的驱动频率。
本实施例提供的触摸显示驱动方法的技术方案中，在未检测出发生触摸动作时在连续多个显示阶段输出触摸行的显示数据并在多个显示阶段之后的一个行消隐阶段输出触摸驱动信号，本实施例采用隔多行进行一次触摸驱动的方案，降低了行消隐阶段的驱动频率，从而降低了驱动模块的功耗。
图4为本发明实施例三提供的一种触摸显示驱动方法的流程图，如图4所示，该方法包括：
步骤301、检测是否发生触摸动作，若否，则执行步骤302；若是，则执行步骤303。
本实施例中各步骤可以由驱动模块执行。优选地，驱动模块为TDDI。驱动模块可用于驱动显示面板，以使显示面板进行显示和触摸。显示面板可包括相对设置的彩膜基板和阵列基板，阵列基板可包括衬底基板和位于衬底基板之上的栅线和数据线，栅线和数据线限定像素单元。
步骤302、在未检测到触摸动作的情况下，以第一帧频在显示阶段输出触摸行的显示数据以用于显示以及在行消隐阶段输出触摸驱动信号以用于触摸，流程结束。
其中，可将全部栅线分为多个栅线组，每个栅线组包括若干条栅线，则每个栅线组为一个触摸行，换言之，一个触摸行可包括多条栅线，例如：一个阵列基板可包括12个触摸行。
本实施例中，显示数据可包括栅极驱动信号和源极驱动信号。
本实施例中，行消隐阶段为长时间行消隐(Long H-Blank，简称：LH-Blank)阶段。
如图3所示，第一个显示阶段中，驱动模块以第一帧频进行显示驱动，即：驱动模块以第一帧频输出第一个触摸行的显示数据给显示面板以供显示面板进行显示；在第一个行消隐阶段中，驱动模块以第一帧频进行触摸驱动，即：驱动模块以第一帧频输出触摸驱动信号以用于触摸。第二个显示阶段中，驱动模块以第一帧频进行显示驱动，即：驱动模块以第一帧频输出第一个触摸行的显示数据给显示面板以供显示面板进行显示；在第二个行消隐阶段中，驱动模块以第一帧频进行触摸驱动，即：驱动模块以第一帧频输出触摸驱动信号以用于触摸。以此类推，直至第十二个显示阶段和之后的第十二个行消隐阶段。
步骤303、在检测到触摸动作的情况下，以第二帧频在显示阶段输出触摸行的显示数据以用于显示以及在行消隐阶段输出触摸驱动信号以用于触摸，第一帧频小于第二帧频。
如图3所示，第一个显示阶段中，驱动模块以第二帧频进行显示驱动，即：驱动模块以第二帧频输出第一个触摸行的显示数据给显示面板以供显示面板进行显示；在第一个行消隐阶段中，驱动模块以第二帧频进行触摸驱动，即：驱动模块以第二帧频输出触摸驱动信号以用于触摸，且驱动模块对触摸产生的感测信号进行接收。第二个显示阶段中，驱动模块以第二帧频进行显示驱动，即：驱动模块以第二帧频输出第一个触摸行的显示数据给显示面板以供显示面板进行显示；在第二个行消隐阶段中，驱动模块以第二帧频进行触摸驱动，即：驱动模块以第二帧频输出触摸驱动信号以用于触摸，且驱动模块对触摸产生的感测信号进行接收。以此类推， 直至第十二个显示阶段和之后的第十二个行消隐阶段。
优选地，第二帧频为第一帧频的两倍。例如：第一帧频为60Hz，第二帧频为120Hz。本实施例中，重复执行步骤301至步骤303，以完成对一帧画面的显示和触摸过程。而后，可继续执行对下一帧画面的显示和触摸过程。
本实施例中，驱动模块若未检测出触摸动作，则以第一驱动模式进行显示驱动和触摸驱动，此时，驱动模块以第一帧频在显示阶段输出触摸行的显示数据以用于显示以及在行消隐阶段输出触摸驱动信号以用于触摸；驱动模块若检测出触摸动作，则以第二驱动模块进行显示驱动和触摸驱动，此时，驱动模块以第二帧频在显示阶段输出触摸行的显示数据以用于显示以及在行消隐阶段输出触摸驱动信号以用于触摸。从上述内容可以看出，第一驱动模式下，无论是在显示阶段还是行消隐阶段，驱动模块均以第一帧频进行驱动；而第二驱动模式下，无论显示阶段还是行消隐阶段，驱动模块以第二帧频进行驱动。由于第一帧频小于第二帧频，因此第一驱动模式下显示阶段和行消隐阶段的驱动频率小于第二驱动模式下显示阶段和行消隐阶段的驱动频率。本实施例采用的变频驱动方案可有效降低驱动频率。
本实施例提供的触摸显示驱动方法的技术方案中，若未检测出发生触摸动作时以第一帧频进行驱动，若检测出发生触摸动作时以第二帧频进行驱动，第一帧频小于第二帧频，本实施例中未检测出发生触摸动作时以较小的第一帧频进行驱动，降低了显示阶段和行消隐阶段的驱动频率，从而降低了驱动模块的功耗。
图5为本发明实施例四提供的一种驱动模块的结构示意图，如图5所示，该驱动模块包括触摸驱动单元11和显示驱动单元12。
触摸驱动单元11用于检测是否发生触摸动作，在未检测出触摸动作时以第一驱动模式进行触摸驱动以及在检测出触摸动作时以第二驱动模式进行触摸驱动。显示驱动单元12用于在所述触摸驱动单元11未检测出触摸动作时以第一驱动模式进行显示驱动，以及在所述触摸驱动单元11检测单元检测出触摸动作时以第二驱动模式进行显示驱动，所述第一驱动模式下的驱动频率小于所述第二驱动模式下的驱动频率。
可选地，在所述触摸驱动单元1111未检测出触摸动作时，显示驱动单元12用于在连续多个显示阶段输出触摸行的显示数据以用于显示；触摸驱动单元11用于在该连续多个显示阶段之后的一个行消隐阶段输出触摸驱动信号以用于触摸。在触摸驱动单元11检测出触摸动作时，显示驱动单元12用于在每个显示阶段输出触摸行的显示数据以用于显示，触摸驱动单元11用于在该显示阶段之后的行消隐阶段输出触摸驱动信号以用于触摸。

或者，可选地，在触摸驱动单元11未检测出触摸动作时，显示驱动单元12用于以第一帧频在显示阶段输出触摸行的显示数据以用于显示；触摸驱动单元11用于在行消隐阶段以第一帧频输出触摸驱动信号以用于触摸。在触摸驱动单元11检测出触摸动作时，显示驱动单元12用于以第二帧频在显示阶段输出触摸行的显示数据以用于显示，以及触摸驱动单元11用于在行消隐阶段以第二帧频输出触摸驱动信号以用于触摸，第一帧频小于第二帧频。优选地，第二帧频为第一帧频的两倍。
具体地，所述显示驱动单元包括栅极驱动器和源极驱动器；所述显示数据包括栅极驱动信号和源极驱动信号。且此时触摸驱动单元11为触摸驱动器(Touch IC)。在所述触摸驱动单元未检测出触摸动作时，所述栅极驱动器用于以第一帧频在显示阶段输出触摸行的栅极驱动信号；所述源极驱动器用于以第一帧频在显示阶段输出触摸行的源极驱动信号；在所述触摸驱动单元检测出触摸动作时，所述栅极驱动器用于以第二帧频在显示阶段输出触摸行的栅极驱动信号；所述源极驱动器用于以第二帧频在显示阶段输出触摸行的源极驱动信号。此种情况下，栅极驱动器、源极驱动器和触摸驱动器均单独设置，而不是集成于一个模块中。此种情况图中不 再具体画出。
本实施例提供的驱动模块可用于实现上述实施例一、实施例二或者实施例三的触摸显示驱动方法，具体描述可参见实施例一、实施例二或者实施例三，此处不再赘述。
本实施例提供的驱动模块的技术方案中，若未检测出发生触摸动作时以第一驱动模式进行驱动，若检测出发生触摸动作时以第二驱动模式进行驱动，第一驱动模式下的触摸驱动频率小于第二驱动模式下的触摸驱动频率，降低了整体驱动频率，从而降低了驱动模块的功耗。
本发明实施例五提供了一种显示装置，该显示装置包括显示面板和驱动模块。该驱动模块可采用上述实施例四提供的驱动模块，此处不再赘述。
其中，驱动模块可用于对显示面板进行显示和触摸驱动。优选地，显示面板可包括相对设置的彩膜基板和阵列基板。优选地，显示装置为盒内触摸显示装置。
