具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开实施例所述的触控显示面板的驱动方法，如图6所示，所述触控显示面板100包括依序排列的L行栅线和依序排列的M条触控扫描线，L和M都为大于1的正整数。需要说明的是，图6为本公开实施例的一种实施方式，在该实施方式中，每两条栅线之间设一条触控线；在本公开的其他实施例中，还可以是多条栅线对应设置一条触控线，即两条触控线之间可以间隔多条栅线。如图2所示，所述驱动方法包括：
步骤21：将所述触控显示面板显示每一帧图像的时间段分为N个控制时段，每个所述控制时段包括顺序设置的显示时间段和触控时间段，N为大于1的整数；
步骤22：在所述触控显示面板显示每一帧图像的时间段内，在N个所述显示时间段内依序驱动所述L行栅线，在N个所述触控时间段内依次驱动所述M条触控扫描线K次，K大于1。
在一方面，本公开实施例所述的触控显示面板的驱动方法，将所述触控显示面板显示每一帧图像的时间段分为N个控制时段，每个控制时间段包括顺序设置的显示时间段和触控时间段，即将一帧的显示时间分为N段，利用显示驱动的空闲时间进行触控驱动，这样做的好处是通过分段扫描使得触控驱动信号能在最短的时间内报告给外部的触控驱动芯片，极大的提高了触控响应速度。
在另一方面，本公开实施例所述的触控显示面板的驱动方法，在所述触控显示面板显示每一帧图像的时间段内，在N个所述显示时间段内依序驱动所述L行栅线，在N个所述触控时间段内依次驱动所述M条触控扫描线K次，K大于1，即在一帧的显示时间内，已经有超过一帧的触控驱动信号反馈给外部的触控驱动芯片，提高了触控驱动频率。
根据一具体实施例所述的触控显示面板的驱动方法中，N为大于M的整数；所述L行栅线按照排列顺序分成N个栅线组。
在所述触控显示面板显示每一帧图像的时间段内，在每个所述显示时间段内，驱动一个所述栅线组，在每一所述触控时间段内，驱动一条所述触控扫描线。
在该具体实施例所述的触控显示面板的驱动方法中，在一帧的显示时间内，一共需驱动L行栅线，将该L行栅线分成N段，N为正整数，并且触控扫描线的总行数M小于N，利用显示驱动的空闲时间进行触控驱动，也就是说触控驱动时间被分成N+1段或N-1段；
在该具体实施例所述的触控显示面板的驱动方法中，触控驱动在显示驱动的空闲时间进行，且触控驱动频率高于显示驱动频率，当驱动完第M条触控扫描线后，从第一条触控扫描线再开始驱动，直到一帧的显示时间结束，第二帧的显示时间起，接续上一帧的触控扫描线开始驱动，而不是如相关技术般总是从第一条触控扫描线开始驱动；例如，在前一帧的显示时间结束时，驱动第P条触控扫描线；P为小于或等于M的正整数；当P小于M时，当后一帧的显示时间开始时，从第P+1条触控扫描线开始驱动；当P等于M时，当后一帧的显示时间开始时，从第一条触控扫描线开始驱动；这样的触控扫描顺序设置可以使得在一帧的显示时间内，已经有超过一帧的触控驱动信号反馈给外部的触控驱动芯片，使得触控驱动频率提高，并且使得前后帧的触控扫描可以跨帧接续，不会因为一帧的显示时间内驱动的触控扫描线的个数并非是触控扫描线的总个数的倍数，就导致触控扫描线驱动的中断。
综上，本公开该具体实施例所述的触控显示面板的驱动方法，在提高了触控驱动频率的同时，提高触控响应速度。
可选的，在不同的控制时段中，每个所述显示时间段的时长均相等，每个所述触控时间段的时长均相等，以便显示驱动控制和触控驱动控制。
图3是本公开该具体实施例所述的触控显示面板的驱动方法的显示驱动信号和触控驱动信号的时序图。
如图3所示，在本公开该具体实施例所述的触控显示面板的驱动方法中，L可以是N的倍数，在第一个显示时间段(1st display refresh time，1st DT)内，依次驱动第一行栅线Gate1至第(L/N)行栅线，在第一个触控时间段(1st TT)内，驱动第一条触控扫描线Tx1；在第二个显示时间段(2nd display refresh  time，2nd DT)内，依次驱动第(L/N+1)行栅线至第(2L/N)行栅线，在第二个触控时间段(2nd TT)内，驱动第二条触控扫描线Tx2；依次类推，直到在第M个显示时间段(Mth display refresh time，Mth DT)内，依次驱动第(M×L/N)行栅线至第(M+1)×L/N行栅线，在第M个触控时间段(Mth TT)内，驱动第M条触控扫描线，至此为止，一帧的显示时间还没有结束，但是已经驱动完M条触控扫描线；在第(M+1)个显示时间段((M+1)th display refresh time，(M+1)th DT)内，依次驱动第((M+1)×L/N+1)行栅线至第(M+2)×L/N行栅线，在第(M+1)个触控时间段((M+1)th TT)内，开始驱动第一条触控扫描线Tx1，依次类推。
本公开该具体实施例所述的触控显示面板的驱动方法，当所述触控显示面板驱动完M条触控扫描线时，还没有驱动完全部的栅线，即在一帧的显示时间内，已经有超过一帧的触控驱动信号反馈给外部的触控驱动芯片，提高了触控驱动频率。
具体的，本公开实施例所述的触控显示面板的驱动方法，在每两个相邻的显示一帧图像的时间段之间设置第一噪声脉冲采集时间段，在该第一噪声脉冲采集时间段内采集显示数据信号噪声、电源干扰噪声和/或热噪声信号等噪声信号作为噪声脉冲。
具体的，本公开实施例所述的触控显示面板的驱动方法，在显示每一帧图像的时间段内，在驱动完M条触控扫描线后，设置第二噪声脉冲采集时间段，在该第二噪声脉冲采集时间段内采集显示数据信号噪声、电源干扰噪声和/或热噪声信号等噪声信号作为噪声脉冲。
在具体实施时，如图4所示，本公开实施例所述的触控显示面板的驱动方法，异步控制触控扫描帧同步信号TSHD和触控扫描行同步信号TSVD，通过改变TSVD的波形、TSHD的波形以及TTSVD，以及采用在一帧显示时间内实现触控扫描信号的顺序非整数倍的驱动方式实现任意触控频率的设置。
假设所述触控显示面板包括L条栅线和M条触控扫描线，将所述触控显示面板显示每一帧图像的时间段分为N个控制时段，每个所述控制时段包括顺序设置的显示时间段和触控时间段，L、M和N都为大于1的整数；
设定N大于M，且N小于2M；
在TTSVD内，当TSVD和TSHD都为高电平时，即在设定的噪声脉冲采集时间段内，不进行显示驱动和触控驱动，采集显示数据信号噪声、电源干扰噪声和/或热噪声信号等噪声信号作为噪声脉冲；当TSVD为高电平而TSHD为低电平时，正常进行显示驱动。
在TTSVD内，当TSVD为低电平而TSHD为高电平时，即在触控时间段依次驱动M条触控扫描线，而当TSVD为低电平而TSHD也为低电平时，即在显示时间段依次驱动M×(L/N)条栅线，如图4所示，当驱动完M条触控扫描线时，还没有完成对L条栅线的扫描，因此触控扫描频率大于显示扫描频率，从而提高了触控响应速度。
在驱动完M条触控扫描线后，设置第二噪声脉冲采集时间段，在该第二噪声脉冲采集时间段内将TSVD和TSHD设置为高电平，采集显示数据信号噪声、电源干扰噪声和/或热噪声信号等噪声信号作为噪声脉冲；而当TSVD为高电平而TSHD为低电平时，正常进行显示驱动。
在图4中，TX1是第一条触控扫描线，TXM是第M条触控扫描线，TXN-M是第N-M条触控扫描线。
在本公开实施例所述的触控显示面板的驱动方法中，增加了噪声脉冲数量，采集了更多的噪声脉冲，通过处理器的IC(集成电路)内部算法进一步提高了信噪比。本公开还提供了一种触控显示面板的驱动装置，所述触控显示面板包括依序排列的L行栅线和依序排列的M条触控扫描线，L和M都为大于1的正整数，如图5所示，所述驱动装置包括：
