附图说明
为了更清楚地说明本公开一些实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简要介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域的普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图8为本公开实施例中的另一种移动设备的结构示意图。
具体实施方式
本公开实施例可应用于移动设备，例如手机，解锁屏幕的场景中。移动设备用于用户手指触碰的解锁区域，内置有一个指纹识别模块，它会将收集到的指纹信息转化为指纹信息数据并加密储存在设定区域。当用户需要解锁移动设备时，移动设备中的电容式、光学式或射频式传感器对指纹进行采集获取指纹图像，由处理器对该指纹图像进行预处理、二 值化和细化等处理，再将提取出来的指纹特征与密储存在设定区域的指纹信息数据进行匹配，最终输出识别结果。
如图1A和图1B可知，相关技术在进行指纹解锁屏幕时，先对指纹进行匹配，当指纹匹配成功后，才开始进行解锁准备以及LCD(Liquid Crystal Display，液晶显示器)初始化过程。另外，在指纹匹配成功后，依次通过移动设备的内核(Kernel)层、硬件抽象(HAL)层、框架(Framework)层向锁屏模块(keygard)层上报keygard层成功指令；keygard层进行解锁界面绘制，并向Framework层下发唤醒指令；Framework层接收到唤醒指令后通过HAL层发送触发Kernel层LCD初始化的指令。因此，当指纹匹配成功、解锁准备以及LCD初始化过程全部完成之后，才会点亮背光屏幕，耗时较长、指纹解锁亮屏的速度较慢。
其中，移动设备的Framework层主要用于操作系统整体运行框架，向应用层提供必要的服务；移动设备的HAL层主要用于整合硬件差异，向Framework层提供统一接口；移动设备的keygard层主要用于锁屏状态管理及控制显示。
而在本公开实施例中，对解锁亮屏的进程进行了改进，移动设备在检测到触碰信号后，在进行指纹匹配操作的同时，进行解锁界面绘制和LCD初始化，由于当移动设备确定指纹匹配成功时，已经完成了解锁界面绘制和LCD初始化，因此可立刻解锁屏幕并点亮LCD，相对于相关技术中需要顺序进行指纹匹配操作和解锁界面绘制、LCD初始化，缩短了整体操作的时间，提高了指纹解锁亮屏的速度和人机交互的效率。
另外，本公开实施例还对移动设备的Kernel层和Framework层进行了改进：当检测到触碰信号后，在进行指纹匹配的操作的同时，Kernel层会通过HAL层向Framework层发送通知消息，Framework层接收到通知消息后，会直接发送触发Kernel层LCD初始化的指令和触发keygard层解锁界面绘制的指令；因此，进一步缩短了LCD初始化的触发时间、加快了亮屏的速度。
为了使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开作进一步地详细描述，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它实施例，都属于本公开保护的范围。
基于上述内容，如图2所示，本公开实施例提供一种移动设备，可包括：处理器200、存储器201、LCD 202和指纹传感器203，其中，存储器201存储有程序代码，当该程序代码被处理器200执行时，使得处理器200执行下列过程：
在锁屏状态时响应于指纹传感器检测到触碰信号，产生用于触发解锁界面绘制和LCD 初始化的中断；
在根据触碰信号进行指纹匹配操作的同时，根据该中断进行解锁界面绘制和LCD初始化；
响应于指纹匹配成功，点亮LCD并显示解锁后的界面。
也就是说，移动设备在检测到触碰信号后，在进行指纹匹配操作的同时，进行解锁界面绘制和LCD初始化，由于当移动设备确定指纹匹配成功时，已经完成了解锁界面绘制和LCD初始化，因此可立刻解锁屏幕并点亮LCD，相对于相关技术中需要顺序进行指纹匹配操作和解锁界面绘制、LCD初始化，缩短了整体操作的时间，提高了指纹解锁亮屏的速度和人机交互的效率。
在一些实施例中，处理器200，可具体配置为响应于指纹匹配成功，确定LCD初始化以及解锁界面绘制是否完成；响应于LCD初始化以及解锁界面绘制完成，点亮LCD并显示解锁后的界面。
在一些实施例中，处理器200，还配置为响应于指纹匹配失败，确定LCD初始化是否完成；响应于LCD初始化完成，释放LCD资源。
在一些实施例中，处理器200，还配置为响应于LCD初始化未完成，等待LCD初始化完成后点亮LCD并显示解锁后的界面或释放LCD资源。
在一些实施例中，处理器200，可具体配置为根据触碰信号进行指纹匹配操作，同时将该中断依次通过移动设备的内核Kernel层和移动设备的硬件抽象HAL层上报到移动设备的框架Framework层，使得Framework层在接收到中断后，通过调用图像合成服务接口的函数向Kernel层发送LCD初始化指令，同时向移动设备的锁屏模块keygard层发送解锁界面绘制指令，Kernel层根据LCD初始化指令进行LCD初始化，keygard层根据解锁界面绘制指令进行解锁界面绘制。
也就是说，当检测到触碰信号后，在进行指纹匹配的操作的同时，Kernel层会通过HAL层向Framework层发送通知消息，Framework层接收到通知消息后，会直接发送触发Kernel层LCD初始化的指令和触发keygard层解锁界面绘制的指令；而无需由keygard层在接收到解锁界面绘制指令后再依次经过Framework层、HAL层向Kernel层发送LCD初始化的指令，因此，进一步缩短了LCD初始化的触发时间、加快了亮屏的速度。
相应地，如图3所示，本公开实施例还提供了一种指纹解锁点亮屏幕的方法，包括：
步骤300：移动设备在锁屏状态时在移动设备的指纹识别区域检测到触碰信号，产生用于触发解锁界面绘制和液晶显示器LCD初始化的中断。
步骤301：移动设备在根据触碰信号进行指纹匹配操作的同时，根据该中断进行解锁 界面绘制和LCD初始化。
步骤302：移动设备响应于指纹匹配成功，点亮LCD并显示解锁后的界面。
本公开实施例中，移动设备在检测到触碰信号后，在进行指纹匹配操作的同时，进行解锁界面绘制和LCD初始化，由于当移动设备确定指纹匹配成功时，已经完成了解锁界面绘制和LCD初始化，因此可立刻解锁屏幕并点亮LCD，相对于相关技术中需要顺序进行指纹匹配操作和解锁界面绘制、LCD初始化，缩短了整体操作的时间，提高了指纹解锁亮屏的速度和人机交互的效率。
下面对本公开实施例一种指纹解锁亮屏的方法进行详细描述。
当移动设备处于锁屏状态时，若有手指触摸或按压移动设备的指纹传感器，此时移动设备会检测到触碰信号并产生用于触发解锁界面绘制和LCD初始化的中断，进而根据该触碰信号进行指纹匹配操作。移动设备在进行指纹匹配操作的同时，还会根据该中断进行解锁界面绘制和LCD初始化。
在移动设备根据中断进行解锁界面绘制和LCD初始化之前，移动设备将响应于触碰信号产生的中断上报到移动设备的Kernel层，移动设备的Kernel层通过移动设备的HAL层通知移动设备的Framework层。
其中，本实施例对移动设备的Kernel层将产生的中断通过移动设备的HAL层通知移动设备的Framework层的具体方式不做限定，能够实现将产生的中断告知Framework层的任何一种实施方式均在本实施例的保护范围之内。
在一些实施例中：移动设备的Kernel层将响应于触碰信号产生的中断以按键的方式添加至相应的文件中来通知移动设备的Framework层。
例如，移动设备的Kernel层将响应于触碰信号产生的中断定义为按键，具体的数值可为188或者其它，并在移动设备内部的KL(key layout，按键定义)和/或KeyEvent.java(按键定义)等文件中添加该按键的定义。
在一些实施例中，Framework层在接收到中断通知后，移动设备根据该中断进行解锁界面绘制和LCD初始化的一种实施方式包括：
移动设备的Framework层接收中断，判断是否开启了指纹解锁功能；
若移动设备的Framework层确定指纹解锁功能未开启，则结束解锁亮屏进程；
若移动设备的Framework层确定指纹解锁功能开启，则向移动设备的Kernel层发送LCD初始化指令，同时向移动设备的keygard层发送解锁界面绘制指令。
其中，移动设备的Framework层向移动设备的Kernel层发送LCD初始化指令的一种实现方式是：移动设备的Framework层通过调用图像合成服务接口函数向移动设备的HAL 层中的图像合成服务的接口发送LCD初始化指令，移动设备的HAL层中图像合成服务的接口再将LCD初始化指令发送至移动设备的Kernel层。
需要说明的是，任何能够实现移动设备的Framework层向移动设备的HAL层中的图像合成服务的接口发送LCD初始化指令的实施方式、以及任何能够实现移动设备的HAL层中的图像合成服务的接口将LCD初始化指令发送至移动设备的Kernel层功能的实施方式均在本公开实施例的保护范围之内。
在一些实施例中，移动设备的Framework层通过调用图像合成服务接口函数向移动设备的HAL层中的图像合成服务的接口发送LCD初始化指令，移动设备的HAL层中图像合成服务的接口将LCD初始化指令发送至移动设备的Kernel层的一种实施方式为：可设置图像合成服务的接口为setPowerMode(int mode)接口，以及设置调用图像合成服务接口的函数为setDisplayMode函数。
例如，预先在移动设备的Framework层中的DisplayManagerService(显示管理服务)模块和SurfaceControl(显示管理服务)模块中增加setDisplayMode的调用图像合成服务接口的函数。
相应地，移动设备的Framework层向移动设备的Kernel层发送LCD初始化指令的具体过程可为：移动设备的Framework层调用SurfaceControl模块中的setDisplayMode函数，以将LCD初始化指令发送至移动设备的Framework层的DisplayManagerService模块；移动设备的Framework层再调用DisplayManagerService模块中的setDisplayMode函数，以将LCD初始化指令发送至移动设备的HAL层中的SurfaceFlinger模块的setPowerMode(int mode)接口；最后，移动设备HAL层的SurfaceFlinger模块的setPowerMode(int mode)接口通过mode参数将LCD初始化指令发送至移动设备的Kernel层。
移动设备的Kernel层接收到LCD初始化指令后进行LCD初始化；移动设备的keygard层接收到解锁界面绘制指令后进行解锁界面绘制。
也就是说，当检测到触碰信号后，在进行指纹匹配的操作的同时，Kernel层会通过HAL层向Framework层发送通知消息，Framework层接收到通知消息后，会直接发送触发Kernel层LCD初始化的指令和触发keygard层解锁界面绘制的指令；而无需由keygard层在接收到解锁界面绘制指令后再依次经过Framework层、HAL层向Kernel层发送LCD初始化的指令，因此，进一步缩短了LCD初始化的触发时间、加快了亮屏的速度。
其中，移动设备的Kernel层进行LCD初始化的具体过程是首先令移动设备上电，进而执行reset复位操作，最后配置寄存器参数；移动设备的keygard层对屏状态进行更新以及对界面重新绘制以进行解锁界面绘制。
LCD初始化以及解锁界面绘制与指纹匹配操作并行处理，移动设备即可根据并行处理结果立即执行点亮LCD或释放LCD资源的操作。
一种情况下，若指纹匹配成功，移动设备的指纹传感器将指纹匹配的结果上报至移动设备的Kernel层，移动设备的Kernel层依次通过移动设备的HAL层和Framework层向移动设备的keygard层发送指纹匹配成功指令；移动设备的keygard层进行屏幕解锁操作，并向移动设备的Framework层发送唤醒指令。移动设备的Framework层接收到唤醒指令后，通过调用图像合成服务接口的函数向移动设备的HAL层中的图像合成服务的接口发送LCD亮屏指令；移动设备的HAL层中的图像合成服务的接口将LCD亮屏指令发送至移动设备的Kernel层。移动设备的Kernel层接收LCD亮屏指令、且已经完成LCD初始化，则移动设备的Kernel层点亮LCD。
需要说明的是，若指纹匹配成功，移动设备的Kernel层接收到LCD亮屏指令且LCD初始化和/或解锁界面绘制还未完成，则移动设备等待LCD初始化和/或解锁界面绘制完成，并在LCD初始化和/或解锁界面绘制完成之后化点亮LCD和/或显示解锁后的界面。
在一些实施例中，点亮LCD的一种实施方式是利用LightService(光服务)模块提供的接口点亮LCD。
如图4所示，其为本公开实施例提供的指纹解锁亮屏的方法在指纹匹配成功的情况下的一种流程示意图。

步骤414：移动设备的Kernel层接收到LCD亮屏指令后点亮LCD。
另一种情况下，若指纹匹配失败，移动设备的指纹传感器将指纹匹配的结果上报至移动设备的Kernel层，移动设备的Kernel层通过移动设备的HAL层将指纹匹配失败指令发送至移动设备的Framework层，移动设备的Framework层通过调用图像合成服务接口的函数向移动设备的HAL层中的图像合成服务的接口发送释放LCD资源指令；移动设备的HAL层中的图像合成服务的接口将释放LCD资源指令发送至移动设备的Kernel层；移动设备的Kernel层接收释放LCD资源指令、且已经完成LCD初始化，则移动设备的Kernel层释放LCD资源。
在一些实施例中，若指纹匹配失败，移动设备的Kernel层接收到释放LCD资源指令且还未完成LCD初始化，则移动设备等待LCD初始化完成，并在LCD初始化完成之后释放LCD资源。
在一些实施例中，释放LCD资源的一种实施方式是利用LightService提供的接口释放LCD资源。移动设备的Kernel层进行LCD资源释放的具体过程是首先令移动设备掉电，进而再执行reset复位操作，最后恢复寄存器参数。

需要说明的是，任何一种能够实现Framework层向Kernel层发送LCD亮屏指令/释放LCD资源指令的实施方式均在本公开实施例的保护范围之内。
在一些实施例中，一种实施方式是：将调用图像合成服务接口的函数设置为setDisplayMode，将图像合成服务的接口设置为setPowerMode(int mode)接口。相应地，移动设备的Framework层向移动设备的Kernel层发送LCD亮屏指令/释放LCD资源指令的具体过程可为：移动设备的Framework层调用SurfaceControl模块中的setDisplayMode函数，以将LCD亮屏指令/释放LCD资源指令发送至移动设备的Framework层的DisplayManagerService模块；移动设备的Framework层再调用DisplayManagerService模块中的setDisplayMode函数，以将LCD亮屏指令/释放LCD资源指令发送至移动设备的HAL层中的SurfaceFlinger模块的setPowerMode(int mode)接口；最后，移动设备的HAL层的SurfaceFlinger模块的setPowerMode(int mode)接口将LCD亮屏指令/释放LCD资源指令发送至移动设备的Kernel层。
