Description

触控检测方法及装置、通信设备及存储介质 技术领域
本公开涉及显示触控技术领域但不限于显示触控技术领域，尤其涉及一种触控检测方法及装置、通信设备及存储介质。
背景技术
随着智能终端设备的性能逐渐提升，用户对设备的触控屏触控灵敏度需求随之提升，例如，在游戏等交互场景下，往往对触控报点率和/或触控检测时长有较高的要求。由于触控报点率的提升往往需要通过提升触控传感器的帧扫描频率实现，而触控传感器的扫描频率受到传感器负载的限制，通常难以超过240Hz。因此，相关技术中的触控报点率较低且受到硬件条件的限制，而且触控检测响应时长也比较长，难以满足用户日渐提升的触控灵敏度需求。
发明内容
本公开实施例提供一种触控检测方法及装置、通信设备及存储介质。
本公开实施例第一方面提供一种触控检测方法，包括：
获取被触控的第一区域；
基于互容扫描方式在第一区域确定被触控位置的位置信息；
基于位置信息执行报点操作。
本公开实施例第二方面提供一种触控检测装置，包括：
获取单元，被配置为获取被触控的第一区域；
确定单元，被配置为基于互容扫描方式在第一区域确定被触控位置的位置信息；
执行单元，被配置为基于位置信息执行报点操作。
本公开实施例第三方面提供一种通信设备，包括处理器、存储器及存储在存储器上并能够有所述处理器运行的可执行程序，其中，所述处理器运行所述可执行程序时执行如前述第一方面提供的触控检测方法。
本公开实施例第四方面提供一种计算机存储介质，所述计算机存储介质存储有可执行程序；所述可执行程序被处理器执行后，能够实现前述的第一方面提供的触控检测方法。
本公开实施例提供的技术方案，获取被触控的第一区域；基于互容扫描方式在第一区域确定被触控位置的位置信息；基于位置信息执行报点操作。如此，确定被触控的大致区域，进而通过互容扫描方式对该区域进行进一步地扫描，可以更加具有针对性地对大致区域内通道形成的点位进行扫描。因此，通过先定位大致区域进而在区域内进行精确的点位扫描，可以减少对触控屏多通道间的 所有点位进行完整的一帧扫描导致的报点速度慢，从而可以提高对触控操作的检测和响应速度，提升触控操作的灵敏度。

请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及 若干个接入设备12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，终端)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
接入设备12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，接入设备12可以是4G系统中采用的演进型接入设备(eNB)。或者，接入设备12也可以是5G系统中采用集中分布式架构的接入设备(gNB)。当接入设备12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对接入设备12的具体实现方式不加以限定。
接入设备12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
可选的，上述无线通信系统还可以包含网络管理设备13。若干个接入设备12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
如图2所示，本公开实施例提供一种触控检测方法，包括：
S110：获取被触控的第一区域；
S120：基于互容扫描方式在第一区域确定被触控位置的位置信息；
S130：基于位置信息执行报点操作。
在本公开实施例中，触控屏可以为电子设备上用于响应用户的触控操作执行对应显示交互操作的屏幕，例如手机、平板电脑、智能手表或者智能家电等设备上的触控屏等。本实施例提供的触控检测方法，可以应用于触控屏的触控芯片(Touch Integrated Circuit Chip，TIC)中，也可以应用于TIC与处理器等组成的触控系统中，例如TIC与应用处理器(Application Processor，AP)等组成的触控处理系统。
在一个实施例中，触控屏内可包含多个通道，每一通道可以对应触控屏中的一个电极。触控屏内可以包括第一通道和第二桶，第一通道对应的电极方向可以与第二通道对应的电极方向垂直。例如，第一通道可以对应于纵向排列的电极，第二通道可以对应于横向排列的电极。多个纵向排列的电极和多个横向排列的电极构成触控屏的触控检测矩阵。
其中，自容扫描方式可以为对触控屏包含的每一通道对应电极的自电容分别进行检测，即对每个通道检测一次。当在一个通道对应的电极位置出现触控，则该电极的自电容会发生一定变化。例如分别检测每一通道对应的电极与地形成的自电容的变化情况，则基于自容扫描方式扫描触控屏所需的检测次数等于触控屏包含的通道总数。
互容扫描方式可以为对每一通道与其他通道的交汇点对应的电容分别进行检测，即对每一通道的检测次数等于该通道与其他通道的交汇点个数。当在一个通道与其他通道的交汇点处或者交汇点所处的一定范围内出现触控操作，该交汇点对应的纵向电极和横向电极间的互电容会发生一定变化。例如，对一个第一通道的互容扫描，可以为扫描该第一通道与所有第二通道的交汇点，即检测第一通道对应的纵向电极与所有第二通道对应的横向电极形成的交叉点的互电容。
相关技术中，对触控屏多通道对应的所有点位进行完整的一帧扫描后才执行报点操作，即对触控屏包含的所有通道形成的所有交汇点进行扫描后，确定其中的触控点并进行报点操作。
在一个实施例中，触控屏包含的多个通道可以如图3所示，示例性的，触控屏可以包含N个第一通道例如N＝18，则Tx1、Tx2、Tx3…Tx18可以代表纵向电极对应的第1个至第18个第一通道。触控屏还可以包含M个第二通道例如M＝36，则Rx1、Rx2…Rx36可以代表横向电极对应的第1个至第36个第二通道。
在一个实施例中，步骤S110可以为：基于被触控的通道确定被触控的第一区域。例如，确定触控屏包含的所有通道中出现电容变化的通道形成的区域为第一区域。再例如，也可以为确定每个通道上出现电容变化的点位中处于该通道最外侧的点位，根据所有通道上的这些点位确定第一区域的轮廓边缘等。
在一个实施例中，步骤S110可包括：基于自容扫描方式对触控屏进行扫描，确定触控屏是否被触控；若触控屏被触控，则获取被触控的第一区域。其中，确定触控屏是否被触控，可以包括根据 触控屏包含的第一通道和/或第二通道中是否存在符合预设条件的电容变化。若至少一个第一通道和/或第二通道存在符合预设条件的电容变化，则确定触控屏被触控。
其中，预设条件可以指示电容值出现变化，或者指示电容值达到预设电容值，或者指示电容值变化量达到预设阈值，或者指示电容值变化比例达到预设比例等。
在一个实施例中，步骤S110可包括：基于自容扫描方式对触控屏进行扫描。例如，可以为依次扫描触控屏包含的所有第一通道和/或第二通道。示例性的，根据通道对应电极的排列顺序，按预设方向依次扫描，例如从上到下或者从左到右等。
在一个实施例中，每完成对触控屏所有第一通道和/或第二通道的一轮自容扫描可以执行一次打码，用以标记已完成的一次自容扫描，然后执行对该触控屏的下一轮自容扫描。
在一个实施例中，获取的被触控的第一区域，可以为触控位置附近的区域。例如，第一区域可以为存在符合预设条件的电容变化的至少一个第一通道和/或第二通道形成的覆盖区域。
示例性的，基于自容扫描方式对触控屏进行扫描，确定第一通道中T n-1、T n和T n+1存在符合预设条件的电容变化，则可以确定T n-1、T n和T n+1形成的覆盖区域为第一区域，或者，确定T n-1、T n和T n+1形成的覆盖区域与附近的一定区域为第一区域。例如，第一区域可以为T n-2、T n-1、T n、T n+1和T n+2形成的覆盖区域。
在一个实施例中，由于第一区域内出现触控操作，则第一区域内一定存在触控位置对应的第一通道与第二通道的交汇点，即第一区域内一定有存在符合预设条件电容变化的交汇点。因此，步骤S120可包括：基于互容扫描方式确定第一区域内存在符合预设条件的电容变化的交汇点；基于存在符合预设条件的电容变化的交汇点的位置信息确定被触控位置的位置信息。
其中，交汇点为第一通道与第二通道的交叉位置，即每一交汇点可以对应一个纵向电极和一个横向电极形成的互电容。若交汇点存在预设条件的电容变化，则表明该交汇点处或者该交汇点附近的一定范围内被触控，可以认为该交汇点属于触控位置。
在一个实施例中，交汇点的位置信息，可以根据交汇点对应的第一通道和第二通道的通道信息确定。例如交汇点对应的第一通道的通道标识为T n，对应的第二通道的第二标识为R m，则基于T n和R m对应的坐标数据可以确定交汇点的坐标数据。
在一个实施例中，基于互容扫描方式确定第一区域内存在符合预设条件的电容变化的交汇点，可以为依次检测第一区域内包含的所有交汇点，确定第一区域内存在符合预设条件的电容变化的交汇点。例如，可以为对一个第一通道上的所有交汇点按预设方向依次检测，然后对下一个第一通道上所有交汇点按预设方向依次检测…等。
在一个实施例中，被触控位置的位置信息，可以包括属于被触控位置的所有交汇点的位置信息，或者，也可以包括当前检测到的属于被触控位置的交汇点的位置信息。
在一个实施例中，每完成对一个目标通道的互容扫描后可以执行一次打码，用以标记对一个目标通道的互容扫描结束，然后执行对下一个目标通道的互容扫描或者对触控屏的下一轮自容扫描。
在一个实施例中，报点操作可以包括将被触控位置的位置信息发送给TIC内部处理器或者AP， 内部处理器或者AP根据位置信息计算确定被触控位置的坐标信息。例如，TIC可以通过串行外设接口(Serial Peripheral Interface，SPI)将位置信息发送给AP。被触控位置的坐标信息可以用于指示在对应的坐标位置执行触控操作对应的处理，例如显示或切换等处理。
如此，通过自容扫描方式扫描触控屏的多个通道而非通道间的点位，从而可以更加快速地确定被触控的大致区域。通过互容扫描方式对该区域中的点位进行进一步地扫描，可以更加具有针对性地在该区域内精准地定位被触控位置，减少对未被触控位置的点位产生大量不必要的扫描。因此，通过自容扫描和互容扫描配合的方式，可以减少对触控屏多通道间的所有点位进行完整的一帧扫描导致的报点速度慢，从而可以提高对触控操作的检测和响应速度。
在一些实施例中，如图4所示，基于自容扫描方式对触控屏进行扫描，获取被触控的第一区域，可包括：
S111：基于自容扫描方式对触控屏的多个第一通道进行扫描；
S112：基于多个第一通道中电容变化符合预设条件的至少一个目标通道，确定被触控的第一区域。
在本公开实施例中，目标通道为存在符合预设条件的电容变化的第一通道，例如，电容变化量达到预设阈值的第一通道，或者，电容值达到预设电容值的第一通道等。
在一个实施例中，基于自容扫描方式对触控屏的多个第一通道进行扫描，可以为依次对触控屏的多个第一通道进行扫描。例如，按预设顺序依次对触控屏的多个第一通道进行扫描。
示例性的，第一通道对应于纵向电极时，预设顺序可以为从左至右，或者，第一通道对应于横向电极时，预设顺序可以为从上至下等。
在一个实施例中，步骤S111可包括：基于自容扫描方式对触控屏的多个第一通道和第二通道进行扫描。例如，依次对触控屏包含的所有第一通道Tx1-TxN，以及所有第二通道Rx1-RxN进行扫描。
在一个实施例中，步骤S112可包括：基于多个第一通道与第二通道中电容变化符合预设条件的至少一个目标通道，确定被触控的第一区域。其中，目标通道为存在符合预设条件的第一通道及第二通道，例如，目标通道为T n-1、T n和T n+1，以及R m-1、R m和R m+1，则T n-1、T n和T n+1以及覆盖的区域可以为第一区域。
如此，根据自容扫描初步确定的目标通道，即为触控位置对应的交汇点所在的目标通道，从而可以确定出被触控位置落于根据目标通道确定的第一区域内。因此，可以快速地确定触控位置所在的大致区域，利于针对性地对该区域进行精确的互容扫描，可以减少对没有发生触控的通道对应的点位进行大量不必要的检测。
在一些实施例中，如图5所示，基于互容扫描方式在所述第一区域确定被触控位置的位置信息，可包括：
S121：基于互容扫描方式对第一区域中每一目标通道与多个第二通道的交汇点依次进行扫描； 第二通道与目标通道对应的电极方向垂直；
S122：基于互容扫描方式的扫描结果在第一区域确定被触控位置的位置信息。
在本公开实施例中，对第一区域中每一目标通道与多个第二通道的交汇点依次进行扫描，可以为按预设顺序对第一区域中每一目标通道与多个第二通道的交汇点依次进行扫描。例如，当目标通道对应纵向电极时，对于一个目标通道内与多个第二通道的交汇点，可以按从上到下的预设顺序依次扫描，对于第一区域中的多个目标通道，可以按从左到右的预设顺序依次扫描。
在一个实施例中，基于互容扫描方式的扫描结果在第一区域确定被触控位置的位置信息，可以包括：基于互容扫描方式的扫描结果确定第一区域内存在符合预设条件电容变化的交汇点，根据存在符合预设条件电容变化的交汇点的位置信息确定被触控位置的位置信息。
在一个实施例中，基于互容扫描方式的扫描结果在第一区域确定被触控位置的位置信息，可以包括：基于互容扫描方式的扫描结果确定第一区域内出现电容变化量相同或者相近的多个交汇点，根据该多个交汇点的位置信息确定被触控位置的位置信息。
其中，电容变化量相同可以指电容变化趋势相同且电容变化量相同，电容变化量相近可以指电容变化趋势相同且电容变化量差值在预设区间范围内。
如此，对基于自容扫描确定的第一区域内进行交汇点的互容扫描，可以更好地节省对第一区域外未被触控区域内的交汇点进行大量不必要扫描消耗的时间，从而在准确检测触控位置的基础上，提高触控检测速度。
在一些实施例中，所述基于所述互容扫描方式的扫描结果在所述第一区域确定被触控位置的位置信息，可包括：
基于所述互容扫描方式的扫描结果确定所述交汇点是否存在符合预设条件的电容变化；
若所述交汇点存在符合预设条件的电容变化，则基于所述第一区域中存在符合预设条件的电容变化的交汇点，确定被触控位置的位置信息。
在本公开实施例中，预设条件可以指示电容值出现变化，或者指示电容值达到预设电容值，或者指示电容值变化量达到预设阈值，或者指示电容值变化比例达到预设比例等。
在一个实施例中，每确定一个交汇点存在符合预设条件的电容变化，或者，每完成确定一个目标通道上的所有交汇点的电容变化，确定该交汇点或该目标通道上存在符合预设条件电容变化的所有交汇点的位置信息，作为被触控位置的位置信息。
相应地，基于位置信息执行报点操作，可以为基于当前确定的存在符合预设条件电容变化的交汇点的位置信息，或者基于当前确定的目标通道上存在符合预设条件电容变化的所有交汇点的位置信息，执行报点操作。
在一个实施例中，基于当前确定的存在符合预设条件电容变化的交汇点的位置信息执行报点操作，可包括将该交汇点位置信息发送给AP，通过AP根据该交汇点位置信息以及当前周期的自容扫描之后确定的所有交汇点位置信息确定被触控位置的坐标信息。
例如，可以通过AP根据当前上报的交汇点位置信息，以及与当前时刻最接近的一次自容扫描打码之后AP接收到的所有交汇点位置信息，确定被触控位置的坐标信息。如此，可以即时更新属于被触控位置的交汇点的位置信息，从而即时更新报点数据，有效提高报点率，利于确定触控位置。
在一些实施例中，基于第一区域中存在符合预设条件的电容变化的交汇点，确定被触控位置的位置信息，可包括：
基于第一区域中存在符合预设条件的电容变化的交汇点对应的通道信息，确定被触控位置的位置信息；通道信息，包括：交汇点对应的第一通道及第二通道的通道标识。
在本公开实施例中，通道标识可以包括通道对应的编号或者ID等，通道标识也可以包括或者对应于通道在触控屏中的坐标信息。

在一个实施例中，根据第一通道及第二通道对应的坐标信息确定被触控位置的位置信息，可以为根据第一通道和第二通道对应的坐标信息确定被触控位置覆盖范围的坐标信息。
在另一个实施例中，根据第一通道及第二通道对应的坐标信息确定被触控位置的位置信息，也可以为根据第一通道及第二通道对应的坐标信息确定第一区域中存在符合预设条件的电容变化的所有交汇点的坐标信息，并根据该所有交汇点的坐标信息确定被触控位置覆盖范围的轮廓对应的坐标信息。
如此，根据交叉形成交汇点的第一通道及第二通道的通道信息，可以更加准确快速地确定交汇点的坐标位置，从而可以用于准确确定被触控位置的坐标信息。
在一些实施例中，基于位置信息执行报点操作，包括：
响应于基于互容扫描方式的扫描结果确定交汇点存在符合预设条件的电容变化，基于当前确定的交汇点确定的位置信息执行报点操作；
或者，
响应于完成对一个目标通道上所有交汇点的互容扫描，基于目标通道上所有存在符合预设条件的电容变化的交汇点确定的位置信息执行报点操作；
或者，
响应于完成对第一区域中所有交汇点的互容扫描，基于存在符合预设条件的电容变化的多个交汇点确定的位置信息执行报点操作。
在本公开实施例中，基于当前确定的交汇点执行报点操作，可以指每确定一个存在符合预设条件的电容变化的交汇点，基于该确定的交汇点执行报点操作。基于存在符合预设条件的电容变化的多个交汇点执行报点操作，可以指基于第一区域内所有属于被触控位置的交汇点执行报点操作。
在一个实施例中，响应于完成对一个目标通道上所有交汇点的互容扫描，基于目标通道上所有存在符合预设条件的电容变化的交汇点确定的位置信息执行报点操作，可以包括：响应于基于互容扫描方式的扫描结果确定交汇点存在符合预设条件的电容变化，且当前确定的交汇点所在目标通道上的所有交汇点已完成互容扫描，基于该目标通道上所有存在符合预设条件电容变化的交汇点确定的位置信息执行报点操作。
在一个实施例中，基于当前确定的交汇点执行报点操作，可以包括：基于当前确定的交汇点对应的目标通道和/或第二通道执行报点操作。例如，基于当前确定的交汇点对应的目标通道和/或第二通道的通道信息执行报点操作。
如此，基于当前确定的交汇点执行报点操作，可以提升报点率，处理器可以实时更新对应交汇点的数据，从而实时更新被触控位置的位置信息，提升报点及触控检测准确性。基于第一区域内所有属于被触控位置的交汇点执行报点操作，可以降低触控检测响应时长，从而提升触控响应速度。
在一些实施例中，基于位置信息执行报点操作，包括：
响应于完成对一个目标通道上所有交汇点的互容扫描，将目标通道的互容扫描结果传输至处理器；
通过处理器基于目标通道的互容扫描结果更新被触控位置的坐标信息；
基于更新的坐标信息执行报点操作。
在本公开实施例中，处理器可以为用于执行报点操作或进行被触控位置确定的处理器，例如TIC中的处理器或者应用处理器AP等。
在一个实施例中，TIC每完成一个目标通道的互容扫描，将该目标通道的互容扫描结果发送给AP，例如将目标通道上存在符合预设条件的电容变化的交汇点位置信息发送给AP，或者将该目标通道所有交汇点的电容变化数据发送给AP等。
在一个实施例中，AP每接收到一个目标通道的互容扫描结果，基于该目标通道的扫描结果更新当前计算到的被触控位置的坐标信息。例如根据该目标通道上存在符合预设条件的电容变化的交汇点位置信息，对被触控位置坐标信息更新。
在一个实施例中，基于更新的坐标信息执行报点操作，可以为基于当前传输的目标通道的互容扫描结果，以及当前第一区域内其他已传输的目标通道的互容扫描结果更新的坐标信息，执行报点操作。
如此，每完成一个通道的互容扫描，可以即时传输给处理器进行实时处理，从而减少单次将所有通道的数据传输给处理器统一处理导致单次计算量过大，进而可以提升处理器响应速度和坐标更新速率，进一步加快触控响应速度。
在一些实施例中，第一区域是基于实际被触控的第二区域确定的；第二区域可包括：至少一个目标通道覆盖的区域。
在本公开实施例中，根据存在符合预设条件的电容变化的目标通道覆盖的第二区域确定的第一区域，可以为与第二区域相同，或者包含第二区域及第二区域附近一定范围的区域等。例如，第一区域可以包含第二区域以及位于第二区域边缘的目标通道相邻且不属于第二区域的第一通道。
示例性的，目标通道为T n-1、T n和T n+1时，第一区域可以为T n-2、T n-1、T n、T n+1和T n+2形成的覆盖区域。
如此确定的第一区域可以包含实际被触控的第二区域，从而提升第一区域判断的容错率，可以更加准确地检测被触控位置。
在一些实施例中，基于位置信息执行报点操作，可包括：
基于位置信息确定被触控位置包含的第一通道与第二通道的通道标识；
基于通道标识确定被触控位置的坐标信息。
在本公开实施例中，被触控位置的位置信息可以包含被触控位置包含的一个或多个交汇点对应的第一通道与第二通道的通道标识。
在一个实施例中，基于通道标识确定被触控位置的坐标信息，可以包括：基于被触控位置包含的所有交汇点对应的通道标识中处于被触控位置边缘的通道标识，确定被触控位置轮廓对应的坐标信息。
例如，在被触控位置包含的通道标识中，根据每一个第一通道上处于边缘位置的通道标识，以及每一个第二通道上处于边缘位置的通道标识，确定被触控位置的轮廓对应的坐标信息。
需要说明的是，本领域内技术人员可以理解，前述公开实施例提供的方法，可以被单独执行，也可以与前述公开实施例中一些方法或相关技术中的一些方法一起被执行。
本公开实施例提供一种触控检测方案，具体可如下：
相关技术中的触控报点方案，如图6所示，需要对一帧扫描计算之后才能实现报点。例如以扫描频率f 0＝240Hz(等于报点频率)时，一帧报点的时间间隔T 0＝1/240*1000≈4.17ms。而理论上触控检测报点所需时长最长可达两倍的帧频间隔，即2*T 0≈8.34mS。因此相关技术中除了触控报点率受到限制之外，触控响应时长也比较长。即报点率f 0＝240Hz时手指点击触控的响应时间范围为[4.17，8.34]ms。
本实施例提出一种提高触控报点率的实现方案，包括：
1、触控芯片TIC通过自容扫描快速确定触控屏是否有手指触控以及手指触控的大致区域。
2、TIC在有手指附近的区域启动互容扫描。
3、TIC将扫描的数据信息通过SPI实时传给AP。
4、AP实时更新对应的通道数据，并根据更新后的通道数据计算出手指坐标信息。
如图7所示，T n-1、T n、T n+1、T m-1、T m、T m+1、T k-1、T k以及T k+1分别为不同的通道。TIC启动自容扫描，定位手指的大致区域，随后启动该区域(如：T n-1、T n、T n+1)的互容扫描。TIC在完成每一个通道的扫描之后就立刻将数据通过SPI传给AP，AP实时更新对应通道的数据，同时AP根 据新的数据计算手指的坐标，并完成报点。
在本公开实施例中，触控的平均报点率和手指点击触控响应时间与手指触控覆盖屏幕的大小相关。当手指触控覆盖面积越大，平均报点率越高，检测到手指点击的最长时间越长。当手指触控覆盖屏幕面积越小，平均报点率越低，检测到手指点击的最长时间越短。
在一些情况下，当手指触控面积大到覆盖整个屏幕时，自容扫描检查到手指覆盖的区域是整个屏，所以互容扫描需要扫描完整的屏幕上所有通道。此时，报点率提高(因为每一个通道互容扫描完成，AP都会更新该通道的数据并报点)。但是通道是按照顺序扫描的，如果手指点击的区域正好是刚扫描过的通道，便需要等到下一次自容扫描，锁定手指区域并启动该区域互容扫描才能检测到。而且由于需要对屏幕上所有通道互容扫描分别进行报点，报点次数多导致检测手指点击触控的最大时间变长。
当手指触控覆盖的区域很小，比如只有1个通道。此时，自容扫描检查到手指，启动对应的一个通道的互容扫描，就可以确定手指的位置。因此相当于这样一次自容扫描，一个通道的互容扫描就可以检测到手指，虽然报点率降低(因为互容扫描的次数减少，报点率则降低)，但是由于报点次数减少，检测手指点击触控的最大时间缩短。
以触控报点率f 0＝240Hz，通道数18(第一通道T x)*36(第二通道R x)为例。自容扫描时长为T s，每个第一通道的互容扫描时长为T m。当手指点击触控覆盖屏幕的T x通道数为x(1≤x≤18)，则触控报点的平均时间间隔T 1＝(T s+x*T m)/x，即平均触控报点率f 1＝1/T 1＝x/(T s+x*T m)。若自容扫描时长与一个第一通道的互容扫描时长相等，则一帧报点的时间间隔即触控检测响应时长T 0＝T s+18*T m＝19*T m，即T m≈4.17/19＝0.219ms。
因此，本实施例提供的触控检测方法对应的平均报点率范围：
当x＝18时，f 1(max)＝x/(T s+x*T m)＝18/(19*T m)＝4.32KHz，对应的最长手指检测时间T D1＝19*T m＝4.17ms，即这种情况下，手指检测的时间范围为：[0.219，4.17]ms。
当x＝1时，f 1(max)＝x/(T s+x*T m)＝1/(2*T m)＝2.28KHz，对应的最长手指检测时间T D1＝2*T m＝0.438ms，即这种情况下，手指检测的时间范围为：[0.219，0.438]ms。
因此，本实施例提供的触控检测方案的触控报点率范围为：[1/(2*T m)，18/(19*T m)]Hz，检测手指触控的最长的时间范围为：[T m，19*T m]ms。而前述相关技术中的触控报点率范围为：1/(18*T m)Hz，检测手指触控的最长时间范围为：[18*T m，36*T m]ms。本实施例的报点率得到提升，且检测手指触控的最长时间降低。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
