Description

一种防止电容触摸屏手机通话中误操作的方法及其手机
技术领域
本发明涉及通信领域，尤其涉及一种防止电容触摸屏手机通话中误操作的方法及其手机。
背景技术
目前，触摸屏手机成为应用的主流手机，其中尤其以电容触摸屏手机的用户体验最好，而用户在打电话时，屏幕与脸部或者头部长时间接触，容易引起错误操作，现有技术中采用的解决办法一般是，在手机上设置一个接近感应传感器，当检测到手机处于通话状态，如果通话中手机靠近人头或者脸部，则将手机屏幕锁住，防止用户通话过程中发生错误操作。
如图1所示的，通常电容触摸屏手机上都会使用一个用于防止用户通话过程中脸部与屏幕接触引起错误操作的接近传感器110。而接近传感器110需要与一个红外发光管120配合使用，不但增加了手机的制造成本，而且这颗接近传感器芯片和周边器件（包括红外发射管）的尺寸不能忽略不计，加上接近传感器和红外发射管需要对红外光的传输路径进行控制，所以两者之间的中心距离需要保持在4mm左右，两者之间要设置结构挡墙，接近传感器和红外发射管还需要放置在听筒附近，从而增加了手机外观和结构的设计难度；并且现有技术中采用的是有光传输，需要在手机的外壳上开洞，增加了手机的制造成本。
现有技术中没有数字键盘的全触摸屏手机，都有一个专门用于锁住手机屏幕的物理按键即锁屏键，放在手机的顶部或者侧边，当手机处于激活状态并且锁屏键按下时，手机会把屏幕关掉并且进入休眠状态；处于锁屏状态或者休眠状态的手机，如果锁屏键被按下的话，会激活手机，点亮屏幕。但锁屏键功能比较单一，限制了其应用空间。
由此可见，现有技术有待于更进一步的改进和发展。
发明内容
本发明为解决上述现有技术中的缺陷提供一种防止电容触摸屏手机通话中误操作的方法及其手机，以防止用户通话过程中发生错误操作，降低手机的制造成本。
为解决上述技术问题，本发明方案包括：
一种防止电容触摸屏手机通话中误操作的方法，其包括以下步骤：
A、在手机中设置一硬件中断模块，按下锁屏键，当手机处于通话状态时，触发所述硬件中断模块判断手机为激活状态或休眠状态；
B、若手机为激活状态，则所述硬件中断模块关闭手机屏幕背光、显示屏模块停止向手机屏幕输出数据以及停止刷屏动作、关闭电容触摸检测模块。
所述的方法，其中，所述方法还包括：
C、所述硬件中断模块判断手机为休眠状态，则所述硬件中断模块激活手机，打开手机屏幕背光、显示屏模块向手机屏幕输出数据以及激活刷屏动作、打开电容触摸检测模块。
所述的方法，其中，所述步骤A还包括：手机中设置一中断服务模块，按下锁屏键，所述中断服务模块判断手机是否为通话状态，若为否，则所述中断服务模块锁住手机屏幕或激活手机屏幕。
所述的方法，其中，所述步骤B还包括：所述硬件中断模块关闭手机屏幕背光、显示屏模块停止向手机屏幕输出数据以及停止刷屏动作、关闭电容触摸检测模块后，再次按下锁屏键，则所述硬件中断模块激活手机，打开手机屏幕背光、显示屏模块向手机屏幕输出数据以及激活刷屏动作、打开电容触摸检测模块。
所述的方法，其中，所述步骤B还包括：所述硬件中断模块激活手机，打开手机屏幕背光、显示屏模块向手机屏幕输出数据以及激活刷屏动作、打开电容触摸检测模块后，再次按下锁屏键，则所述硬件中断模块关闭手机屏幕背光、显示屏模块停止向手机屏幕输出数据以及停止刷屏动作、关闭电容触摸检测模块。
一种手机，其中，在手机中增加一用于判断手机为激活状态或休眠状态以及锁住手机屏幕或激活手机屏幕的硬件中断模块。
所述的手机，其中，所述手机还包括一中断服务模块与一锁屏键，硬件中断模块分别与中断服务模块、锁屏键通信连接。
本发明提供了一种防止电容触摸屏手机通话中误操作的方法及其手机，通过在手机中增加硬件中断模块，判断手机的状态，然后通过锁屏键的操作，实现了准确锁住手机屏幕或激活手机屏幕的功能，提高了用户操作的准确率，避免了用户通话过程中发生错误操作，并且使手机取消了接近传感器和红外发射管这一机械结构，释放了手机空间，降低了手机外观和结构的设计难度，降低了手机的制造成本，是现有技术的极大进步。

具体实施方式
本发明提供了一种防止电容触摸屏手机通话中误操作的方法及其手机，为了使本发明的目的、技术方案以及优点更清楚、明确，以下将结合附图与实施例，对本发明进一步详细说明。
本实用新型提供了一种防止电容触摸屏手机通话中误操作的方法，采用模块化方式取代现有技术中机械结构方式，防止了用户通话过程中发生错误操作，降低了手机的制造成本。如图2所示的，其主要包括以下步骤：
步骤101：在手机中设置一硬件中断模块，按下锁屏键，当手机处于通话状态时，触发所述硬件中断模块判断手机为激活状态或休眠状态，若手机为激活状态转步骤102，若手机为休眠状态转步骤103；
步骤102：若手机为激活状态，则所述硬件中断模块关闭手机屏幕背光、显示屏模块停止向手机屏幕输出数据以及停止刷屏动作、关闭电容触摸检测模块；
步骤103：若手机为休眠状态，则所述硬件中断模块激活手机，打开手机屏幕背光、显示屏模块向手机屏幕输出数据以及激活刷屏动作、打开电容触摸检测模块。
通过上述描述可知，通过模块化运行拓展了锁屏键的功能，使用户根据需要来控制手机屏幕的状态，避免了用户通话过程中发生错误操作，尤其是采用模块化替代了现有技术中机械结构方式，降低了手机的制造成本，释放了手机空间，降低了手机外观和结构的设计难度。
为了更进一步的提高本发明的性能，所述步骤101还包括：手机中设置一中断服务模块，按下锁屏键，所述中断服务模块判断手机是否为通话状态，若为否，则所述中断服务模块锁住手机屏幕或激活手机屏幕。方便了用户体验操作。
更进一步的，为了方便用户切换锁屏与解锁的操作，所述步骤102还包括：当所述硬件中断模块关闭手机屏幕背光、显示屏模块停止向手机屏幕输出数据以及停止刷屏动作、关闭电容触摸检测模块后，再次按下锁屏键，则所述硬件中断模块激活手机，打开手机屏幕背光、显示屏模块向手机屏幕输出数据以及激活刷屏动作、打开电容触摸检测模块。
而当所述硬件中断模块激活手机，打开手机屏幕背光、显示屏模块向手机屏幕输出数据以及激活刷屏动作、打开电容触摸检测模块后，再次按下锁屏键，则所述硬件中断模块关闭手机屏幕背光、显示屏模块停止向手机屏幕输出数据以及停止刷屏动作、关闭电容触摸检测模块。
为了更进一步的描述，在中断服务模块的条件判断中增加一个是否“手机处于通话状态或者呼入呼出振铃状态”。当锁屏键被按下时，触发硬件按键中断，此按键中断进入中断服务模块的中断响应队列等待执行，当系统响应此中断时，执行相应的中断服务程序。
而该中断服务模块首先判断手机是否处于通话状态或者呼入呼出振铃状态；如果不是，按照上面所述现有的操作方法执行锁屏功能；如果手机处于通话状态或者呼入呼出振铃状态，再判断当前系统工作状态是处于激活状态（手机屏幕处于亮的激活状态）还是待机休眠状态（手机屏幕处于关闭状态）；如果手机处于激活状态，则硬件中断模块关闭手机屏幕背光、显示屏模块停止向手机屏幕输出数据以及停止刷屏动作、关闭电容触摸检测模块，防止误触发产生；如果手机处于休眠状态，则硬件中断模块激活手机，打开手机屏幕背光、显示屏模块向手机屏幕输出数据以及激活刷屏动作、打开电容触摸检测模块，开始检测触摸动作。
为了描述方便，假设锁屏关闭手机屏幕背光、显示屏模块停止向手机屏幕输出数据以及停止刷屏动作、关闭电容触摸检测模块；解锁为打开手机屏幕背光、显示屏模块向手机屏幕输出数据以及激活刷屏动作、打开电容触摸检测模块，开始检测触摸动作。为了方便用户操作，若手机处于通话状态，其有如下操作：
当有电话呼入或者呼出且已接通时，有两种锁屏方法供用户使用：
第一种：用户按下锁屏键锁屏进入锁屏状态，但手机不进入休眠状态；
第二种：手机屏幕提示用户是否要进入锁屏状态，选“是”进入锁屏状态且不进入休眠状态；
通话过程中，如果用户需要操作屏幕，按下锁屏按键激活手机和屏幕；
通话过程中，用户可以反复进行锁屏和解锁操作；
通话结束时，手机屏幕自动解锁，手机和屏幕处于激活状态，供用户操作。
通过两种锁屏方式实现了锁屏功能，方便了用户体验操作。
本发明提供了一种手机，如图3所示的，在现有技术中的手机内增加一用于判断手机为激活状态或休眠状态以及锁住手机屏幕或激活手机屏幕的硬件中断模块301。并且手机还包括一中断服务模块302与一锁屏键303，硬件中断模块301分别与中断服务模块302、锁屏键303通信连接。使手机取消了接近传感器和红外发射管这一机械结构，释放了手机空间，降低了手机的制造成本。并且上述手机可以按照如图2所示的方法进行操作，方便了用户体验操作。
应当理解的是，上述针对较佳实施例的描述较为详细，并不能因此而认为是对本发明专利保护范围的限制，本领域的普通技术人员在本发明的启示下，在不脱离本发明权利要求所保护的范围情况下，还可以做出替换、简单组合等多种变形，这些均落入本发明的保护范围之内，本发明的请求保护范围应以所附权利要求为准。
