Description

一种触控屏的触控响应方法、装置以及终端 技术领域
本发明实施例涉及电子技术领域，尤其涉及一种触控屏的触控响应方法、装置以及终端。
背景技术
触控屏(Touch panel)又称为触控面板、触摸屏，为可接收触头输入的触控信号的感应式液晶显示装置。当触头接触了显示屏幕上的图形按钮时，显示屏幕上的触觉反馈系统可根据预先编程的应用程序驱动各种连结装置。触控屏可用以取代机械式的按钮面板，并借由液晶显示画面制造出生动的影音效果。
配置有触控屏的终端在使用过程中往往会发生冻屏现象，即触控屏无法响应触头输入的触控信号。造成冻屏现象的原因有很多，例如：终端放在裤袋中时触控屏和大腿接触，当检测到自动唤醒屏幕事件(例如来电或者接收到通知消息)时，触控屏处于亮屏状态，可接收触头输入的触控信号，由于触控屏和大腿接触，大腿是导体，则大腿可以作为触头向触控屏输入触控信息，触控屏将会生成基线(Baseline)，触控屏生成基线的过程中受与触控屏接触的大腿的影响，有部分基线异常产生鬼点，鬼点将导致触控屏无法响应触控信号。由此可见，如何避免终端产生冻屏现象是目前亟需解决的问题。
发明内容
本发明实施例提供了一种触控屏的触控响应方法以及终端，可避免无法响应触控屏中触控点的触控操作的情况，提升触控操作的处理效率。
本发明第一方面提供一种触控屏的触控响应方法，包括：检测作用于触控屏的至少两个触控点的触控压力值；比较至少两个触控点的触控压力值的大小，得到至少一个有效触控点，有效触控点的触控压力值大于至少两个触控点中无效触控点的触控压力值；确定有效触控点的触控操作，执行触控操作。
经过研究发现，当作用于触控屏的触控点为鬼点时，鬼点的触控压力值趋 近于零。另外，用户单手操作终端时通常由于手掌和触控屏接触导致误触，该误触产生的触控点的触控压力值较小。另外，用户在操作终端的过程中存在小孩抓住手机或者无目的点击触控屏的现象，小孩抓住手机或者无目的点击触控屏产生的触控点的触控压力值较小。而用户输入操作指令时产生的触控点的触控压力值较大，例如用户点击图像预览界面中的具有拍照功能的虚拟按键时的点击力度较大，用户多点触控显示界面以调整显示界面的尺寸时各个触控点的点击力度较大。传统的终端，无论Windows系统，Android系统，iOS系统，还是各种APP，在当前显示界面均只响应预设手势数据库中的触控手势(例如单点触控、多点触控、长按、滑动或多点滑动等)，当出现鬼点或者存在与预设数据库中的触控手势不匹配的触控操作时，将无法响应该触控操作。基于此，提出了如下技术方案：终端在检测到作用于触控屏的至少两个触控点时，通过力传感器检测各个所述触控点的触控压力值，对检测到的各个触控点的触控压力值进行比较，得到至少一个有效触控点，有效触控点的触控压力值大于检测到的至少两个触控点中无效触控点的触控压力值，确定有效触控点的触控操作，并执行该触控操作，可避免终端无法响应触控屏中触控点的触控操作的情况，提升触控操作的处理效率。
其中，作用于触控屏的至少两个触控点的触控压力值各不相同，终端可以将触控压力值较大的触控点作为有效触控点，并将触控压力值较小的触控点作为无效触控点，有效触控点的触控压力值大于无效触控点的触控压力值。例如，终端可以将作用于触控屏的至少两个触控点中触控压力值最大的触控点作为有效触控点，并将作用于触控屏的至少两个触控点中除有效触控点以外的其他触控点作为无效触控点。又如，终端可以按照触控压力值由大到小(或者由小到大)的顺序对各个触控点进行排序，在作用于触控屏的至少两个触控点中获取触控压力值较大的触控点，获取到的触控点的数量小于或者等于触控屏中当前显示界面所支持的触控点数量，终端可以将获取到的触控点作为有效触控点，并将作用于触控屏的至少两个触控点中除有效触控点以外的其他触控点作为无效触控点。又如，终端可以将作用于触控屏的至少两个触控点中触控压力值大于预设压力阈值的触控点作为有效触控点，并将作用于触控屏的至少两个触控点中除有效触控点以外的其他触控点作为无效触控点。
其中，力传感器可以包括电阻应变片压力传感器、半导体应变片压力传感器、压阻式压力传感器、电感式压力传感器、电容式压力传感器、谐振式压力传感器及电容式加速度传感器等。
其中，触控操作可以为拍照、接听来电或者播放音乐等，具体不受本发明实施例的限制。
可选的，终端比较至少两个触控点的触控压力值的大小，得到至少一个有效触控点，具体可以为：获取触控压力值最大的触控点，将触控压力值最大的触控点作为有效触控点。例如，检测到作用于触控屏的触控点包括第一触控点、第二触控点以及第三触控点，终端通过力传感器检测到第一触控点的触控压力值为1N，第二触控点的触控压力值为2N，第三触控点的触控压力值为10N，其中第三触控点的触控压力值最大，则终端可以将第三触控点作为有效触控点。
可选的，终端比较至少两个触控点的触控压力值的大小，得到至少一个有效触控点，具体可以为：获取触控屏中当前显示界面所支持的触控点数量，比较至少两个触控点的触控压力值的大小，得到至少一个有效触控点，有效触控点的数量小于或者等于当前显示界面所支持的触控点数量。
例如，终端检测到作用于触控屏的触控点为三个时，终端可以通过力传感器检测各个触控点的触控压力值，其中触控屏中的当前显示界面为拍照应用中的图像预览界面，终端获取到该图像预览界面所支持的触控点数量为一个，则终端可以对检测到的各个触控点的触控压力值进行比较，将触控压力值最大的触控点确定为有效触控点。
又如，终端检测到作用于触控屏的触控点为三个时，终端可以通过力传感器检测各个触控点的触控压力值，其中触控屏中的当前显示界面为图像界面，终端获取到该图像界面所支持的触控点数量为两个，则终端可以对检测到的各个触控点的触控压力值进行比较，将触控压力值最大的触控点作为有效触控点。可选的，终端可以将触控压力值较大的两个触控点或触控压力值最大的触控点作为有效触控点。
在该技术方案中，有效触控点的数量小于或者等于当前显示界面所支持的触控点数量，执行有效触控点的触控操作，可避免用户作用于触控屏的数量大于触控屏中当前显示界面所支持的触控点数量时，终端对于任一触控点的触控 操作均不执行，可提升触控操作的处理效率。
可选的，终端确定有效触控点的触控操作，并执行触控操作，具体可以为：在至少一个有效触控点中确定触控压力值最大的有效触控点，当触控压力值最大的有效触控点的触控手势与预设手势数据库中的指定手势匹配时，执行触控压力值最大的有效触控点的触控操作。其中，预设手势数据库中存储至少一个手势，例如在触控屏中具有拍照功能的虚拟按键所属位置进行点击操作，或者在触控屏中的图像界面进行滑动操作等。
具体实现中，终端可以将预设手势数据库划分为多个手势资源池，不同显示界面对应不同的手势资源池，例如拍照界面对应的手势资源池可以包括：单击具有拍照功能的虚拟按键，单击具有图像显示功能的虚拟按键，滑动具有对焦功能的对焦框等。终端在至少一个有效触控点中确定触控压力值最大的有效触控点之后，可以将触控压力值最大的有效触控点的触控手势与触控屏中当前显示界面对应的手势资源池中的手势进行比较，当触控压力值最大的有效触控点的触控手势与触控屏中当前显示界面对应的手势资源池中的手势匹配时，执行触控压力值最大的有效触控点的触控操作。当触控压力值最大的触控点的触控手势与触控屏中当前显示界面对应的手势资源池中的手势不匹配时，终端可以在至少一个有效触控点中确定触控压力值第二大的有效触控点，其中触控压力值第二大的有效触控点的触控压力值小于触控压力值最大的有效触控点的触控压力值且大于其他有效触控点的触控压力值，，当触控压力值最大的有效触控点与触控压力值第二大的有效触控点结合构成的两点触控手势与预设手势数据库中的指定手势匹配时，或当触控压力值第二大的有效触控点的触控手势与预设手势数据库中的指定手势匹配时，执行所匹配的指定手势对应的触控操作。可选的，当触控压力值最大的有效触控点的触控手势与触控屏中当前显示界面对应的手势资源池中的手势不匹配时，终端可以在至少一个有效触控点中确定触控压力值第二大的有效触控点，当触控压力值最大的有效触控点与触控压力值第二大的有效触控点结合构成的多点触控手势与预设手势数据库中的指定手势匹配，或与当前显示界面对应的手势资源池中的手势匹配时，执行触控压力值最大的有效触控点与触控压力值第二大的有效触控点结合构成的多点触控手势的触控操作。
可选的，终端比较至少两个触控点的触控压力值的大小，得到至少一个有效触控点，具体可以为：比较至少两个触控点的触控压力值与预设压力阈值的大小，触控压力值大于预设压力阈值的触控点为有效触控点。其中，预设压力阈值可以为预先设定的触控压力值，例如10N(牛顿)，具体不受本发明实施例的限制。例如，终端通过力传感器检测到各个触控点的触控压力值之后，可以将检测到的触控压力值中大于预设压力阈值的触控点确定为有效触控点。又如，终端通过力传感器检测到各个触控点的触控压力值之后，可以将检测到的触控压力值中大于预设压力阈值的触控点确定为备选触控点，获取触控屏中当前显示界面所支持的触控点数量，在备选触控点中确定有效触控点，有效触控点的数量小于或者等于该触控点数量。经研究发现，鬼点或者误操作的触控点的触控压力值较小，而大于预设压力阈值的触控压力值对应的触控点的触控操作是用户希望终端执行的。
可选的，终端对检测到的各个触控点的触控压力值进行比较，得到至少一个有效触控点之后，可以获取各个有效触控点的触控轨迹，检测触控轨迹为滑动轨迹的有效触控点的触控操作，并执行触控轨迹为滑动轨迹的有效触控点的触控操作。其中，触控轨迹可以包括单击、双击、长按或者滑动等。
示例性的，终端在同一时间段检测到触控轨迹为长按的第一触控点，触控轨迹为滑动轨迹的第二触控点和第三触控点，以及触控轨迹为单击的第四触控点，其中第一触控点的触控压力值小于其他任一触控点的触控压力值，终端可以确定有效触控点为第二触控点、第三触控点以及第四触控点，其中第二触控点以及第三触控点的触控轨迹为滑动轨迹，则终端可以执行第二触控点以及第三触控点的触控操作，提升触控操作的处理效率。

具体实施方式
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一部分实施例，而不是 全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参见图1，图1为本发明一实施例中提供的一种终端的电路示意图，如图所示本发明实施例中的终端可以包括：触控屏(Touch Panel)、力传感器(Force Sensor)以及应用处理器(ApplicationProcessor，AP)等，其中触控屏通过应用处理器的引脚I2C/SPI与应用处理器之间建立通信连接，其中：
触控屏，用于检测作用于该触控屏的触控点。
力传感器，用于检测作用于触控屏的至少两个触控点的触控压力值。
应用处理器，用于比较所述至少两个触控点的触控压力值的大小，得到至少一个有效触控点，有效触控点的触控压力值大于至少两个触控点中无效触控点的触控压力值，确定有效触控点的触控操作，并执行该触控操作。
以图2所示的触控屏与力传感器之间的结构示意图为例，触控屏可以由Cover Lens Glass(玻璃镜片)、Polarizing Film(偏光板)、Rx ITO(与接收电极连接的ITO薄膜，ITO薄膜是一种n型半导体材料，具有高的导电率、高的可见光透过率、高的机械硬度和良好的化学稳定性)、CF Glass(液晶玻璃镜片)、Segmented VcomTx ITO(与分段投射电容式触控的驱动电极连接的ITO薄膜)、Color Filter(滤色片)、LCD Material and Spacer Beads(LCD材料隔膜)、TFT ITO(pixel windows)(TFT ITO像素窗，TFT是薄膜晶体管的简称)、TFT Glass(薄膜晶体管玻璃镜片)、Polarizing Film以及LCD Backlight Module(液晶显示器背光模组)层叠设置而成，其中力传感器位于触控屏的下方，即在力传感器的表面设置触控屏中的LCD Backlight Module。
进一步的，触控屏可以包括电阻式触控屏、电容感应式触控屏、红外线式触控屏以及表面声波式触控屏，以图3所示的电容式触控屏为例，电容式触控屏由TPIC(降压/升压开关模式稳压器)、柔性电路板(Flexible Printed Circuit，FPC)、Lens(镜片)和Sensor(传感器)组成，其中电容式触控屏通过应用处理器的I2C引脚与应用处理器进行连接。
具体实现中，力传感器可以将用户作用于触控屏的触控点的力的量值转换为电信号，根据预先建立的电信号和触控压力值得对应关系，获取该电信号对应得触控压力值，将该触控压力值作为该触控点的触控压力值。例如，力传感 器包括弹性构件和应变片时，应变片可以牢固粘贴在弹性构件表面上，弹性构件受力时产生形变，使应变片电阻值变化(发生应变时，应变片几何形状和电阻率发生改变，导致电阻值变化)，力传感器可以通过电阻变化量得到该触控点的触控压力值。其中应变片可由金属箔或者半导体材料制成。又如，力传感器可以包括压电晶体，力传感器可以基于压电效应，通过压电晶体把力转换为置于晶体两面电极上的电位差，根据电位变化量得到该触控点的触控压力值。又如，力可以引起机械谐振系统固有频率变化，则力传感器可以通过频率变化量得到该触控点的触控压力值。又如，力传感器可以基于电磁力与待测力的平衡，由平衡时相关电磁参数获得力的信息，得到该触控点的触控压力值。
本发明实施例中的终端可称之为用户设备(User Equipment，简称为“UE”)、移动台(Mobile Station，简称为“MS”)、移动终端(Mobile Terminal)，计算机，微机等。该终端可以经无线接入网(Radio Access Network，简称为“RAN”)与一个或多个核心网进行通信，例如，终端可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等，例如，终端还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。本发明对此并不限定，例如终端还包括具有多承载特征的有线接入的终端。
请参见图4，图4为本发明一实施例中提供的一种触控屏的触控响应方法的流程示意图，如图所示本发明实施例中的触控屏的触控响应方法可以包括：

终端在检测到作用于触控屏的至少两个触控点时，可以通过力传感器检测各个触控点的触控压力值。
以图5a所示的触控屏的界面示意图为例，检测到来电呼入时，终端的触控屏更新为亮屏状态，终端通过触控屏检测到作用于触控屏的触控点可以包括A1、A2以及A3，终端可以通过力传感器检测上述各个触控点的触控压力值。

在可选实施例中，终端可以检测预设时间段内同时作用于触控屏的至少两个触控点，并通过力传感器检测同时作用于触控屏的至少两个触控点的触控压力值。其中，预设时间段可以为预先设定的时长，例如1min或者5min等。例如，预设时间段为1min，终端检测到当前作用于触控屏的触控点包括第一触控点和第二触控点，从检测到第一触控点和第二触控点开始经过30s的时间段内检测到作用于触控屏的触控点为第三触控点，则终端可以通过力传感器分别检测第一触控点、第二触控点以及第三触控点的触控压力值。又如，预设时间段为1min，终端检测到当前作用于触控屏的触控点包括第一触控点和第二触控点，从检测到第一触控点和第二触控点开始经过2min的时间段内检测到作用于触控屏的触控点为第三触控点，则终端可以通过力传感器分别检测第一触控点以及第二触控点的触控压力值。本发明实施例通过力传感器检测预设时间段内作用于触控屏的触控点的触控压力值，可避免将与当前系统时间间隔较长的时间段检测到的触控点作为有效触控点，提升触控操作的处理效率。

以图5b所示的触控屏的界面示意图为例，终端检测到作用于触控屏的至少两个触控点包括F1以及F2，通过力传感器检测到F2的触控压力值大于F1的触控压力值，当触控屏中当前显示界面所支持的触控点数量为一个时，终端可以将触控压力值最大的触控点(即F2)确定为有效触控点，将F1确定为无效触控点，并确定F2的触控操作，进而执行该触控操作。可选的，当触控屏中当前显示界面所支持的触控点数量为两个时，终端可以将触控压力值最大的触控点(即F2)的触控手势与预设手势数据库中的指定手势进行匹配，当F2的触控手势与预设手势数据库中的指定手势匹配时，终端可以将F2确定为有效触控点，将F1确定为无效触控点，并确定F2的触控操作为单击具有拍照功能的虚拟按键，进而终端可以执行拍照指令。可选的，当触控屏中当前显示界面所支持的触控点数量为两个时，终端可以将F1以及F2的触控手势与预设手势数据库中的指定手势进行匹配，当F1以及F2所属多点触控的触控手势与预设手势数据库中的指定手势匹配时，终端可以将F1以及F2确定为有效触控点，并确定F1以及F2所属多点触控的触控操作，进而执行该触控操作。
