为使得本发明实施例的发明目的、特征、优点能够更加的明显和易懂，下面将结合本发明实施例中的附图，对本发明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发明实施例一部分实施例，而非全部实施例。基于本发明中的实施例，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，都属于本发明实施例保护的范围。
实施例一
参照图1，示出了根据本发明实施例一的一种触摸屏调整方法的步骤流程图。
本实施例的触摸屏调整方法包括以下步骤：
步骤S102：接收与触摸屏所在终端设备的使用场景类型对应的特征信号。
本发明实施例中，预先对触摸屏所在的终端设备的使用场景进行了分类，以形成多种不同的使用场景类型，通过使用场景类型可以有效对终端设备的使用场景进行区分，并按类型设定相对应的触摸屏调整参数，以调整优化触摸屏在不同使用场景下的表现。
触摸屏所在的终端设备可以有多种使用场景类型，包括但不限于：运行设定应用类型，其中，设定应用可以由本领域技术人员根据实际需要适当设置，设定应用可以为某一个应用，也可以为某一类应用(如具有某些共同特性的应用，如游戏类应用、社交类应用、阅读类应用、图像类应用，等等)；另外，使用场景类型还可以包括握持类型、非握持类型、运动类型、非运动类型，等等。其中，握持类型表征终端设备当前处于被用户握持的状态；非握持类型表征终端设备当前处于未被用户握持的状态，如放于桌上等；运动类型表征终端设备当前正处于运动状态，如处于晃动、抖动等状态，该状态可能由多种可能因素引发，如运动、乘坐汽车驶于颠簸道路等等；非运动类型则与运动类型相反，表征终端设备当前处于非运动状态。在实际应用中，本领域技术人员可以采用任意适当的手段确定终端设备的当前使用场景类型，如，通过检测终端设备的当前状态确定其当前使用场景类型，若检测到终端设备当前处于运动状态，则可确定其当前使用场景类型为运动类型，等等。
针对每个使用场景类型，都有一特征信号与其对应，不同的使用场景类型的特征信号不同。其中，特征信号可以由本领域技术人员采用任意适当形式实现，可以标志并区分不同的使用场景类型即可，如，通过数字形式、或字符形式、或字符与数字相结合形式、或者其它适当形式，等等。
本步骤中，在确定了终端设备的使用场景类型后，即可生成或确定或获取与其对应的特征信号，例如，终端设备的主控端确定使用场景类型并生成对应的特征信号后，将该特 征信号发送给控制触摸屏的触控芯片，由触控芯片接收该与终端设备的使用场景类型对应的特征信号。
步骤S104：获取与所述特征信号相对应的触摸屏调整参数。
因特征信号与终端设备的使用场景类型对应，因此，与特征信号对应的触摸屏调整参数也与终端设备的使用场景类型对应。其中，触摸屏调整参数包括：控制触摸屏的触控芯片的芯片模拟参数和/或固件算法参数。
其中，芯片模拟参数用于指示触控芯片运行时使用的部分模拟信号参数，包括但不限于：PGA(Programmable Gain Amplifier，可编程增益)放大系数、打码时间(电容式触摸屏每个采样周期中驱动通道输出脉冲信号的持续时间)；固件算法参数用于指示触控芯片运行其固件算法时使用的部分参数，包括但不限于：触摸检测阈值、坐标划动速度判断阈值、坐标轨迹平滑系数、坐标去抖强度、报点率卡控上限(触控芯片(固件)对报点率的卡控上限值，如，假设触控芯片可达到的最高报点率为A，考虑到降低触控芯片功耗或降低主控负载等因素，触控芯片会将报点率限制为最高不超过B(B<A)，其中B即为报点率卡控上限)。
步骤S106：根据触摸屏调整参数，调整触摸屏的工作状态。
在确定了使用场景类型对应的触摸屏调整参数后，即可将触摸屏的运行参数调整为与当前使用场景类型相适应的所述触摸屏调整参数。
通过本实施例，预先对终端设备的使用场景进行了分类，形成了不同的使用场景类型，并且，终端设备的不同使用场景类型对应于不同的特征信号。当终端设备在某种类型的使用场景下时，接收到可以指示该使用场景类型的特征信号，获取与该特征信号相对应的触摸屏调整参数，根据该调整参数，对触摸屏在该类型的使用场景下的工作状态进行调整。其中，触摸屏调整参数可以是触控芯片的芯片模拟参数和/或固件算法参数。通过表征使用场景类型的特征信号，触控系统可以根据此特征信号自动地调整自身的参数，以实现自身功能和性能表现的调整，优化该类型的使用场景下用户体验需求较倾向的指标项，使用户在各种使用场景下使用触摸屏都可以得到优异体验。
本实施例的触摸屏调整方法可以由任意适当的具有数据处理功能的设备或装置实现，包括但不限于触控芯片(如控制触摸屏的触控芯片)、MCU(Microcontroller Unit，微控制单元)(如控制触摸屏的MCU，或者触摸屏所在设备的MCU)等。
实施例二
参照图2，示出了根据本发明实施例二的一种触摸屏调整方法的步骤流程图。
本实施例的触摸屏调整方法包括以下步骤：
步骤S202：接收与触摸屏所在终端设备的使用场景类型对应的特征信号。
其中，所述使用场景类型包括以下至少之一：运行设定应用类型、非握持类型、运动类型。当然，相对应地，还可以有运行非设定应用类型、握持类型、非运动类型。
本实施例中，设定由触摸屏所在终端设备的主控端对终端设备的当前使用场景类型进行检测和确定，具体的检测手段可以由本领域技术人员根据实际需求适用任意适当手段实现，本发明实施例对此不作限制。
主控端对终端设备进行检测并确定其当前的使用场景类型后，会生成相应的特征信号，并将该特征信号发送给触控芯片，触控芯片接收该特征信号。本发明实施例中，特征信号可以采用任意适当的形式，可以标志并区分不同的使用场景类型即可。
步骤S204：获取与所述特征信号相对应的触摸屏调整参数。
其中，触摸屏调整参数包括：控制触摸屏的触控芯片的芯片模拟参数和/或固件算法参数。
本发明实施例中，所述芯片模拟参数包括以下至少之一：PGA放大系数、打码时间；所述固件算法参数包括以下至少之一：触摸检测阈值、坐标划动速度判断阈值、坐标轨迹平滑系数、坐标去抖强度、报点率卡控上限。
本步骤中，若所述特征信号指示使用场景类型为运行设定应用类型，则获取与所述特征信号对应的打码时间、坐标轨迹平滑系数、和报点率卡控上限中的至少一个；若所述特征信号指示使用场景类型为非握持类型，则获取与所述特征信号对应的PGA放大系数和/或触摸检测阈值；若所述特征信号指示使用场景类型为运动类型，则获取与所述特征信号对应的坐标去抖强度。
步骤S206：根据触摸屏调整参数，调整触摸屏的工作状态。
针对前述不同使用场景类型，对应有不同的触摸屏调整参数，以根据该触摸屏调整参数，实现触摸屏自动调整自身的运行参数和/或工作流程，提升当前使用场景下的关键指标的表现，提升用户体验。
例如，若所述特征信号指示使用场景类型为运行设定应用类型，则获取的触摸屏调整参数包括：与所述特征信号对应的打码时间、坐标轨迹平滑系数、和报点率卡控上限中的至少一个。则，在根据触摸屏调整参数，调整触摸屏的工作状态时，可以根据所述特征信号对应的打码时间，将触摸屏的打码时间调整为高于运行设定应用类型之外的其它 应用类型的打码时间；和/或，根据所述特征信号对应的坐标轨迹平滑系数，将触摸屏的坐标轨迹平滑系数调整为低于所述其它应用类型的坐标轨迹平滑系数；和/或，根据所述特征信号对应的报点率卡控上限，将触摸屏的报点率卡控上限调整为高于所述其它应用类型的报点率卡控上限。
又例如，若所述特征信号指示使用场景类型为非握持类型，则获取的触摸屏调整参数包括：与所述特征信号对应的PGA放大系数和/或触摸检测阈值。则，在根据触摸屏调整参数，调整触摸屏的工作状态时，可以根据所述特征信号对应的PGA放大系数，将触摸屏的PGA放大系数调整为高于握持类型的PGA放大系数；和/或，根据所述特征信号对应的触摸检测阈值，将触摸屏的触摸检测阈值调整为低于握持类型的触摸检测阈值。其中，握持类型与非握持类型为相反的两种类型，握持类型表示终端设备当前正被用户握持着，而非握持类型则正好相反，表示终端设备当前未被用户握持。
再例如，若所述特征信号指示使用场景类型为运动类型，则获取的触摸屏调整参数包括：与所述特征信号对应的坐标去抖强度。则，在根据触摸屏调整参数，调整触摸屏的工作状态时，可以根据所述特征信号对应的坐标去抖强度，将触摸屏的坐标去抖强度调整为高于非运动类型的坐标去抖强度。其中，运动类型与非运动类型为相反的两种类型，运动类型表示终端设备当前处于运动状态，而非运动类型则表示终端设备当前处于非运动状态。
以下，以具体实例对上述触摸屏调整过程进行说明。
(一)使用场景类型为运行设定应用类型
本实例中的设定应用具体为游戏应用。游戏应用相较于一般的应用(如微信等社交类应用、浏览器类应用等)，更注重触摸操作如手指点击的响应速度、划动操作的坐标跟随程度(前者越快则游戏能越快响应用户的输入，后者跟随程度越好则持续操作流畅感越强)，而对功耗、坐标轨迹平滑程度的要求等则会相对降低。
若要提高对手指点击的响应速度就需要提高触摸屏的报点率，提高报点率最直接可行的调整方式是调整触控芯片对报点率的控制(常规情况下，因为要考虑功耗，所以刷新率的默认设置不会是最高)。另外配合报点率的提高，需要相对应缩短扫描周期，因此在信噪比满足条件的情况下，可适当缩短打码采样的时间，即打码时间，以及，提高报点率卡控上限。
若要提高划动操作的坐标跟随程度，则需要对坐标平滑处理进行调整，坐标平滑处理 是为改善人手划动操作过程中的抖动而引入，可以使划线轨迹更圆滑、少毛刺。为提高坐标跟随程度，可适当降低触控芯片对原始的坐标轨迹的平滑处理程度，使上报的坐标更接近采样的原始坐标。也即，可以降低坐标平滑处理程度。
由上可见，在游戏应用的使用场景中，可以对打码时间、坐标轨迹平滑系数、和报点率卡控上限中的一个或多个(两个及两个以上)进行调整，以优化触摸屏在游戏应用中的表现。
主控端(如Android系统)通过当前应用切换(包括打开新应用、从后台切换)触发判断是否进入到设定的应用类型。例如，若当前应用切换到指定的游戏应用时，通过IIC(Inter-Integrated Circuit，集成电路总线)向触控芯片的指定寄存器写入表征“进入游戏应用”的状态标识；触控芯片通过在工作循环中校验到此状态标识写入，则调整TX(驱动电极)打码时间、报点率卡控上限和坐标轨迹平滑系数为针对“游戏应用”所配置的参数。而当从游戏应用切换到非游戏应用时，通过IIC向触控芯片的指定寄存器写入表征“退出游戏应用”的状态标识；触控芯片通过在工作循环中校验到此状态标识写入，则调整相应的参数为正常工作状态所用参数。
其中，触摸芯片的处理流程如图3所示，包括以下步骤：
步骤S302：接收到状态标识。
本实例中，特征信号采用状态标识的形式。
步骤S304：检测并确定接收到的状态标识为与游戏应用相关的状态标识。
步骤S306：判断状态标识的值是否合法；若合法，则执行步骤S308；若不合法，则执行步骤S324。
其中，通过判断状态标识的值是否合法，可以对数据进行校验，防止数据错误，避免后续处理中引发的错误或异常。
步骤S308：根据所述状态标识的值，判断是否为进入游戏应用的状态标识；若是，则执行步骤S310；若否，则执行步骤S316。
步骤S310：在保证容值采样结果抖动小于阈值情况下，将打码时间调整为游戏应用的打码时间。
其中，所述阈值可以由本领域技术人员根据实际情况适当设置，例如，可以根据硬件情况(如TP叠构、ITO图案、设备系统地与通常人体间电容大小等)和调试需求(如需要支持的最小touch面积即灵敏度需求、需要支持的最慢和最快点击速度等)等条件而定。可选地，所述阈值可设定为触摸有效阈值的1/4。所述打码时间可以采用游戏应用的设置。
步骤S312：将报点率卡控上限调整为高报点率卡控上限。
其中，所述“高报点率卡控上限”可以由本领域技术人员根据实际需求适当设置，如，可以设置为160Hz～200Hz中的任意值。
步骤S314：减小坐标轨迹平滑系数，将坐标轨迹平滑调整为弱平滑。转步骤S324执行。
其中，所述“弱平滑”可以由本领域技术人员根据实际需求适当设置，如，可以设置为当前帧实际数据占输出数据比重2/3以上的平滑处理。
步骤S316：判断是否为退出游戏应用的状态标识；若是，则执行步骤S318；若否，则执行步骤S324。
步骤S318：将打码时间调整为正常打码时间。
其中，“正常打码时间”可以由本领域技术人员根据游戏应用的灵敏度需求、要求适应的环境干扰大小等设定，如，可设定为每帧8ms的打码(采样)时间。
步骤S320：将报点率卡控上限调整为正常报点率卡控上限。
其中，“正常报点率卡控上限”可以由本领域技术人员根据游戏应用的体验需求进行设定，如，设定为80Hz～100Hz中的任意值。
步骤S322：将坐标轨迹平滑调整为正常平滑。转步骤S324执行。
其中，“正常平滑”可以由本领域技术人员根据游戏应用的实际需求进行设定，如，设定为当前帧实际数据占输出数据比重约2/3～1/2的平滑处理。
步骤S324：坐标计算及优化。
如，对坐标进行区域搜索、坐标计算及配对、坐标去抖、坐标轨迹平滑等处理。
步骤S326：坐标上报。返回步骤S302执行。
由上述过程可见，通过本实例，在游戏应用的使用场景下，触摸屏在点击响应速度和坐标跟随程度方面会有优于其它应用的表现。
需要说明的是，以上仅以游戏应用为示例，对触摸屏在运动设定应用类型的使用场景类型下的调整进行了说明，但本领域技术人员可以参考本实例，使用上述参数，或者使用上述参数和其它相关参数，实现触摸屏在其它类型的应用场景下的调整。
(二)使用场景类型为非握持类型
终端设备的使用场景类型为非握持类型时，也即，终端设备当前处于非握持(悬浮)状态下时，其灵敏度由目前互耦式电容触摸屏技术决定。终端设备在握持状态和非握持(如 放置于桌面等绝缘面)状态下，同等条件的触摸引起的电容值变化会有差别。非握持状态下人体与终端设备、触控芯片系统地之间的电容较小，通过触摸经人体耦合到系统地的驱动信号量相对较小，所以触控芯片检测到的电容值变化会较小。
在触摸屏的开发调试阶段，在调试触摸灵敏度时，若统一以非握持状态作为参考，则此灵敏度对握持状态有可能过高。因此，默认地将触摸屏的灵敏度调节为较普遍的使用场景——握持状态的灵敏度需求，在非握持状态下，则可通过触控芯片适当的自适应提高灵敏度，达到这两种使用场景下灵敏度相对一致。
为此，对灵敏度的调节可以采用降低触摸检测阈值，和/或，提高触控芯片采样的信号放大系数(即PGA放大系数)的方式。
主控端(如Android系统)通过设备状态检测触发判断终端设备是否进入到非握持状态。若检测到终端设备由握持状态切换为非握持状态时，通过IIC向触控芯片的指定寄存器写入表征“非握持状态”的状态标识；触控芯片通过在工作循环中校验到此状态标识写入，则调整PGA放大系数和触摸检测阈值为针对“非握持状态”所配置的参数。而当从非握持状态切换到握持状态时，通过IIC向触控芯片的指定寄存器写入表征“握持状态”的状态标识；触控芯片通过在工作循环中校验到此状态标识写入，则调整相应的参数为握持状态所用参数。
其中，触摸芯片的处理流程如图4所示，包括以下步骤：
步骤S402：接收到状态标识。
本实例中，特征信号采用状态标识的形式。
步骤S404：检测并确定接收到的状态标识为与非握持状态相关的标识。
步骤S406：判断状态标识的值是否合法；若合法，则执行步骤S408；若不合法，则执行步骤S420。
步骤S408：根据所述状态标识的值，判断是否为进入非握持状态的状态标识；若是，则执行步骤S410；若否，则执行步骤S414。
步骤S410：在保证容值采样结果抖动小于阈值情况下，将PGA放大系数提高。
其中，将PGA放大系数提高的具体程度可以由本领域技术人员根据实际的灵敏度需求和要求适应的环境干扰大小进行设定，如，可以设置将PGA放大系数比握持状态提高约1/3。
步骤S412：降低触摸检测阈值。执行步骤S420。
其中，降低触摸检测阈值的具体程度可以由本领域技术人员根据实际的灵敏度需求和 要求适应的环境干扰大小进行设定，如，可以设置触摸检测阈值可比握持状态降低约1/3。
需要说明的是，在实际使用中，提高PGA放大系数和降低触摸检测阈值的执行可以不分先后顺序，也可以并行执行。
步骤S414：判断是否为握持状态的状态标识；若是，则执行步骤S416；若否，则执行步骤S420。
步骤S416：将PGA放大系数调整为默认值。
其中，所述默认值可以由本领域技术人员根据实际的灵敏度需求和要求适应的环境干扰大小进行设定，如，设置为对原始信号放大到其1.5倍。
步骤S418：将触摸检测阈值调整为默认值。
其中，所述默认值可以由本领域技术人员根据实际的灵敏度需求和要求适应的环境干扰大小进行设定，如，设置为容值变化的2.5％。
步骤S420：坐标计算及优化。
步骤S422：坐标上报。返回步骤S402执行。
由上述过程可见，通过本实例，在非握持类型的使用场景下，触摸屏在灵敏度方面会有更优的表现。
(三)使用场景类型为运动类型
当终端设备的使用场景类型为运动类型时，因终端设备的过度晃动或抖动，可能造成点击稳定度下降。例如，当终端设备的使用者处于运动状态(如快跑、乘坐汽车驶于颠簸道路等)下使用终端设备，持续按压的操作可能会由于过度的晃动而不稳定，导致触控芯片检测到的电容值变化区域也不稳定，坐标出现抖动。
因此，在通过对终端设备的运动状态(晃动\抖动程度)进行检测后，确定终端设备处于过度晃动\抖动的运动类型的使用场景下，则可使触控芯片加强对原始坐标的去抖处理程度。
为此，对去抖处理的调节可以采用提高坐标去抖强度的方式。
主控端(如Android系统)通过设备运动状态检测及设备过度抖动判断触发判断终端设备是否进入到运动状态。若检测到终端设备由正常状态切换为运动状态时，通过IIC向触控芯片的指定寄存器写入表征“运动状态”的状态标识；触控芯片通过在工作循环中校验到此状态标识写入，则通过增强坐标去抖强度，将其调整为针对“运动状态”所配置的参数。而当从运动状态切换到正常状态时，通过IIC向触控芯片的指定寄存器写入表征“正 常状态”的状态标识；触控芯片通过在工作循环中校验到此状态标识写入，则调整相应的参数为正常状态所用参数。
其中，触摸芯片的处理流程如图5所示，包括以下步骤：
步骤S502：接收到状态标识。
本实例中，特征信号采用状态标识的形式。
步骤S504：检测并确定接收到的状态标识为与运动状态相关的标识。
步骤S506：判断状态标识的值是否合法；若合法，则执行步骤S508；若不合法，则执行步骤S520。
步骤S508：根据所述状态标识的值，判断是否为进入运动状态的状态标识；若是，则执行步骤S510；若否，则执行步骤S514。
步骤S510：根据前几帧原始坐标移动情况，在坐标处于非持续同向运动情况下，增强坐标去抖强度。执行步骤S516。
例如，假设只有正上下左右四个方向，取判断帧数为5帧，即当前帧之前的5帧，若5帧坐标数据中相邻前后帧对比，坐标都是向左移动，则可判定为持续同向运动；若有一次某2帧之间判断到不是向左运动，则判定为非持续同向运动。
在确定坐标处于非持续同向运动情况下，增强坐标去抖强度。其中，坐标去抖的具体实现可以由本领域技术人员根据实际需求采用任意适当的去抖方式，本发明实施例对此不作限制。可选地，增强坐标去抖强度可以将坐标去抖强度提升至原坐标去抖强度的1.1～1.5倍。
步骤S512：判断是否为正常状态的状态标识；若是，则执行步骤S514；若否，则执行步骤S516。
步骤S514：将坐标去抖强度调整为正常强度。
如，调整为系统设定的非运动状态下的坐标去抖强度。
例如，将坐标划动速度判断阈值和坐标轨迹平滑系数均调整为默认值。
步骤S516：坐标计算及优化。
步骤S518：坐标上报。返回步骤S502执行。
由上述过程可见，在接收到终端设备切换到运动状态的信号之后，触控芯片根据触摸屏当前帧之前的若干帧坐标的运动情况，去调整去抖处理的强度，即，若前若干帧坐标经过判断后被判定为“非持续同向运动”，则增强坐标去抖强度。通过本实例，在运动类型的使用场景下，触摸屏在防抖稳定方面会有更优的表现。
通过前述对多种不同使用场景类型下的触摸屏的调整，可以有效提升触摸屏关键指标的表现，提升用户体验。
进一步地，基于调整后的触摸屏，还可以进行步骤S208的操作。
