以下各实施例的说明是参考附加的图式,用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语,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发明,而非用以限制本发明。
在图中,结构相似的单元是以相同标号表示。
请参照图1,图1为本发明的触控信号扫描方法应用的触控显示装置的结构示意图。该触控显示装置10包括至少一个触控芯片11、多条触控驱动线12以及多条触控感应线13。触控芯片11用于发送触控驱动信号以及接收触控感应信号;触控芯片11分别与触控驱动线12和触控感应线13连接。
该触控显示装置10正常使用时,触控芯片11逐行向触控驱动线12发送触控驱动信号,然后触控芯片11接收触控感应线13的触控感应信号,最后触控芯片11根据触控感应信号得到触控操作在触控显示面板上的横坐标,即触控感应线13(Rx1至Rxm)的坐标;并根据触控感应信号的返回时间,得到触控操作在触控显示面板上的纵坐标,即触控驱动线12(Tx1至Txn)的坐标。上述操作触控芯片需要对整个触控显示面板的所有触控驱动线12进行逐行扫描,当触控显示面板的显示分辨率较高时,触控芯片11的触控扫描的耗时较多,如不断减小触控芯片11的触控扫描时间,可能会影响触控显示装置10的触控效果。
本发明的触控信号扫描方法作用于图1的触控显示装置10,可在不影响触控显示装置的触控效果的基础上,大大减少触控芯片11的触控扫描时间。具体请参照图2,图2为本发明的触控信号扫描方法的第一优选实施例的流程图。本优选实施例的触控信号扫描方法包括:
步骤S201,触控芯片向所有的触控驱动线发送第一触控驱动信号;
步骤S202,触控芯片检测所有的触控感应线的第一触控感应信号;
步骤S203,触控芯片根据所有的触控感应线的第一触控感应信号以及预设规则,确定至少一条待扫描的触控感应线;
步骤S204,触控芯片向待扫描的触控感应线发送第二触控驱动信号;
步骤S205,触控芯片通过触控驱动线接收第二触控感应信号;
步骤S206,触控芯片根据第二触控感应信号确定触控操作的位置;
本优选实施例的触控信号扫描方法结束于步骤S206。
下面详细说明本优选实施例的触控信号扫描方法的各步骤的具体流程。
在步骤S201中,触控芯片向所有的触控驱动线(Tx1至Txn)发送第一触控驱动信号;随后转到步骤S202。
在步骤S202中,触控感应线(Rx1至Rxm)根据触控驱动线上的第一触控驱动信号以及触控显示面板上的触控操作生成第一触控感应信号;随后触控芯片检测所有触控感应线的第一触控感应信号;随后转到步骤S203。
在步骤S203中,触控芯片根据触控感应线的第一触控感应信号以及预设规则,确定至少一条待扫描的触控感应线;该预设规则可根据用户的要求以及触控显示装置的要求(如多点触控或单点触控等)进行设置;随后转到步骤S204。
在步骤S204中,触控芯片向待扫描的触控感应线发送第二触控驱动信号,这里触控芯片对待扫描的触控感应线进行了第二次扫描,由于在步骤S201至步骤S203中通过一次整体扫描以及预设规则大大减少了第二次扫描的区域,因此第二次扫描的耗时较短;随后转到步骤S205。
在步骤S205中,触控驱动线根据触控感应线上的第二触控驱动信号以及触控显示面板上的触控操作生成第二触控感应信号;随后触控芯片检测触控驱动线的第二触控感应信号;随后转到步骤S206。
在步骤S206中,触控芯片根据步骤S205获取的第二触控感应信号驱动该触控操作的位置。
这样即完成了本优选实施例的触控信号扫描方法的触控信号的扫描过程。

本优选实施例的触控信号扫描方法的步骤S301和步骤S302和第一优选实施例的步骤S201和步骤S202相同。
在步骤S303中,触控芯片根据触控感应线的第一触控感应信号,直接将信号量最大的触控感应线设定为待扫描的触控感应线。由于单点触控显示装置最多只有一个触控操作点,因此触控操作所在的触控感应线的感应信号的信号量一定为最大。随后转到步骤S304。
本优选实施例的触控信号扫描方法的步骤S304和步骤S305和第一优选实施例的步骤S204和步骤S205相同。
在步骤S306中,触控芯片在步骤S305获取第二触控感应信号对应的触控驱动线,在步骤S303获取待扫描的触控感应线,第二触控感应信号对应的触控驱动线和待扫描的触控感应线的交点即为单点触控操作的位置。
这样即完成了本优选实施例的触控信号扫描方法的触控信号的扫描过程。
本发明的触控信号扫描方法根据单点触控显示装置的单点触控操作的特征,通过两次扫描操作,确定单点触控操作的位置;缩短了触控扫描的时间,且不影响单点触控显示装置的触控效果。
请参照图4A和图4B,图4A为本发明的触控信号扫描方法的第三优选实施例的流程图,图4B为本发明的触控信号扫描方法的第三优选实施例的触控信号示意图。本优选实施例的触控信号扫描方法用于单点触控显示装置,其包括:
步骤S401,触控芯片给所有的触控驱动线发送第一触控驱动信号;
步骤S402,触控芯片检测所有的触控感应线的第一触控感应信号;
步骤S403,根据所有的触控感应线的第一触控感应信号,确定信号量最大的触控感应线以及与信号量最大的触控感应线前后相邻的n条触控感应线为待扫描的触控感应线;

步骤S405,触控芯片通过触控驱动线接收第二触控感应信号;
步骤S406,触控芯片根据第二触控感应信号对应的触控驱动线以及第二触控驱动信号对应的触控感应线确定触控操作的位置;
下面详细说明本优选实施例的触控信号扫描方法的各步骤的具体流程。
在步骤S401中,触控芯片同时向所有的触控驱动线(Tx1、Tx2、……Txn)发送第一触控驱动信号,如图4B所示。随后转到步骤S402。
在步骤S402中,触控感应线(Rx1、Rx2、……Rxm)根据触控驱动线上的第一触控驱动信号以及触控显示面板上的触控操作生成第一触控感应信号;随后触控芯片检测所有触控感应线的第一触控感应信号;随后转到步骤S403。
在步骤S403中,触控芯片根据触控感应线的第一触控感应信号,直接将信号量最大的触控感应线Rxi设定为待扫描的触控感应线。由于单点触控显示装置最多只有一个触控操作点,因此触控操作所在的触控感应线的感应信号的信号量一定为最大。同时为了避免检测误差,这里同时将信息量最大的触控感应线Rxi前后相邻的n条触控感应线设定为待扫描的触控感应线,这里n为正整数,优选为1,即在本步骤中设定了三条待扫描的触控感应线,即触控感应线Rx(i-1)、触控感应线Rxi以及触控感应线Rx(i+1)。随后转到步骤S404。
在步骤S404中,触控芯片逐行对步骤S403中设定的待扫描的触控感应线(Rx(i-1)、Rxi、Rx(i+1))发送第二触控驱动信号,这里触控芯片对待扫描的触控感应线进行了第二次扫描,由于在步骤S401至步骤S403中通过一次整体扫描以及最大信息量的预设规则大大减少了第二次扫描的区域,因此第二次扫描的耗时较短;随后转到步骤S405。
在步骤S405中,触控驱动线根据触控感应线上的第二触控驱动信号以及触控显示面板上的触控操作生成第二触控感应信号;随后触控芯片检测触控驱动线的第二触控感应信号;随后转到步骤S406。
在步骤S406中,触控芯片在步骤S405获取第二触控感应信号对应的触控驱动线,在步骤S403获取待扫描的触控感应线,第二触控感应信号对应的触控驱动线和待扫描的触控感应线的交点即为单点触控操作的位置。如步骤S404中对待扫描的触控感应线Rxi发送第二触控驱动信号,触控芯片检测到触控驱动线Txi具有第二触控感应信号,则将待扫描的触控感应线Rxi和触控驱动线Txi的交点设定为单点触控操作的位置。
这样即完成了本优选实施例的触控信号扫描方法的触控信号的扫描过程。

在步骤S504中,触控芯片逐行对步骤S503中设定的待扫描的所述触控感应线发送第二触控驱动信号,这里触控芯片对待扫描的触控感应线进行了第二次扫描,由于在步骤S501至步骤S503中通过一次整体扫描以及信息量设定值的预设规则大大减少了第二次扫描的区域,因此第二次扫描的耗时较短;随后转到步骤S505。
本优选实施例的触控信号扫描方法的步骤S505和第三优选实施例的步骤S405相同。
