本发明实施例有益效果如下:
本发明实施例提供的触摸屏点亮方法和装置、 移动终端, 能够在触摸 屏熄灭的状态下接收用户的触屏输入, 并在触屏输入与预先设定的触屏操 作一致时, 将触摸屏点亮。 由于触摸屏面积较大, 很容易被用户触碰到, 用户只需根据手与终端的相对位置就近在触摸屏上进行触屏输入即可将触 摸屏点亮。 这样就避免了用户忙乱之中寻找电源键或 Home键、 为了按下 电源键或 Home键以点亮触摸屏而不得不改变终端握持姿势等等不便, 有 效地提升了用户体验。 附图说明
图 1 是本发明的实施例提供的触摸屏点亮方法的一种流程图; 图 2 是本发明实施例中执行触摸屏点亮方法的装置的结构示意图; 图 3 是本发明的实施例提供的触摸屏点亮方法的一种详细的流程图; 图 4是本发明的实施例提供的触摸屏点亮装置的一种结构示意图; 图 5 是本发明的实施例提供的触摸屏点亮装置的另一种结构示意图; 图 6是本发明的实施例提供的触摸屏点亮装置的另一种结构示意图。 具体实施方式
以下结合附图, 对本发明实施例进行进一步详细说明。 应当理解, 此 处所描述的具体实施例仅仅用以解释本发明, 并不限定本发明。
如图 1 所示, 本发明的实施例提供一种触摸屏点亮方法, 包括以下步 骤:
511 , 接收用户在触摸屏熄灭的状态下进行的触屏输入;
512,当所述触屏输入与预先设定的触屏操作一致时,点亮所述触摸屏。 本发明实施例提供的触摸屏点亮方法, 能够在触摸屏熄灭的状态下接 收用户的触屏输入, 并在触屏输入与预先设定的触屏操作一致时, 将触摸 屏点亮。 由于触摸屏面积较大, 很容易被用户触碰到, 用户只需根据手与 终端的相对位置就近在触摸屏上进行触屏输入即可将触摸屏点亮。 这样就 避免了用户忙乱之中寻找电源键或 Home (返回主界面 )键、 为了按下电源 键或 Home键以点亮触摸屏而不得不改变终端握持姿势等等不便, 有效地 提升了用户体验。
优选的, 为了保证触摸屏熄灭的状态下, 仍然能够接收用户的触屏输 入, 中央控制器可以设置触摸屏芯片在所述触摸屏熄灭后处于低功耗模式, 以从所述触摸屏芯片接收用户的触屏输入。 也就是说, 用于处理触摸屏相 关操作的触摸屏芯片不像其他芯片一样在触摸屏熄灭后进入休眠模式, 而 是进入一种低功耗模式, 以从所述触摸屏芯片接收用户的触屏输入。 在所 述低功耗模式中, 所述触摸屏芯片的触屏输入管脚监听用户的触屏输入, 而其他管脚则处于挂起状态或断电状态, 不能执行相应的管脚功能。 这样, 此模式中的触摸屏芯片仅运行一个小的触摸中断程序, 待机电量仅有几毫 安, 在完成传递触屏中断信号的功能的前提下并不会显著增加终端的功耗。
其中, 所述触摸屏芯片的触屏输入管脚既可以与触摸屏点亮状态下用 于接收触摸屏输入的管脚相同, 也可以是在触摸屏芯片原有的未定义管脚 中新定义的管脚。 例如, 如图 2所示, 在本发明的一个实施例中, 在终端 的触摸屏上设置有触控感测电路, 触控感测电路的输出端与触摸屏芯片上 新使能的触屏输入管脚 P1相连, 其中, 触屏输入管脚 P1被使能为通用 I/O 端口, 可以用于输入或输出数据。 当灭屏状态下有触屏输入时, 该触屏输 入就通过触屏输入管脚 P1传送到触摸屏芯片内部, 触摸屏芯片产生触屏中 断信号并通过中断输出管脚 P2将中断信号发送给终端的中央控制器。 中央 控制器比较触屏输入和预先设置的触屏操作, 如果两者一致, 则唤醒整个 终端系统并点亮触摸屏, 如果两者不一致, 则等待下一次触屏中断事件的 发生。
优选的, 在本发明的一个实施例中, 还可以为触摸屏芯片处于低功耗 模式的状态设定一个规定时间, 设置触摸屏芯片在所述触摸屏熄灭后的规 定时间内处于低功耗模式, 以在所述规定时间内从所述触摸屏芯片接收用 户的触屏输入, 而超过该规定时间后, 如果屏幕还没有被点亮, 则使该触 摸屏芯片进入挂起或断电状态, 以进一步降低触摸屏芯片的功耗。
可选的, 触屏输入可以包括常用的触屏操作, 如点击、 长按、 滑动等。 在接收到这些触屏输入时, 终端的中央控制系统可以将这些触屏输入与预 先设定的触屏操作相比较, 当所述触屏输入与预先设定的触屏操作一致时, 点亮所述触摸屏。
其中, 所述预先设定的触屏操作可以通过接收用户的触屏操作设定, 也可以在所提供的几种触屏操作方案中选择一种, 还可以通过其他方式进 行设定, 本发明的实施例对此不做限定。
为了使用以点亮触摸屏的触屏输入能够在一定程度上防止误操作的发 生, 即防止用户不经意间的一个微弱的触屏动作引起触摸屏的点亮, 或者 防止终端被放置在包内或口袋内, 由摩擦等引起的触摸屏点亮, 预先设定 的触屏操作应具有一定的规律性。 例如, 可选的, 所述预先设定的触屏操 作包括点击、 长按、 滑动中的至少一种, 按照规定顺序、 以规定时间间隔 作用在所述触摸屏上。 即, 预先设定的触屏操作包括了多个具体触屏动作 的组合, 例如, 所述预先设定的触屏操作可以包括依次点击两下、 滑动一 下, 或者在所述触摸屏上滑动出规定的图案, 如三角形等, 只要该预先设 定的触屏操作具有一定的规律性并且可以较方便地被用户实现即可, 本发 明的实施例对此不做限定。
其中, 规定间隔时间用来区分一个组合中的每一个独立的触屏动作, 输入的结束。 在本发明的一个实施例中, 该规定时间间隔设置为小于 1秒钟。 也就是说, 当两个点击动作间隔时间小于 1 秒钟时, 这两个点击动作被确定为属于同 一个触屏输入, 当两个点击动作的间隔时间大于或等于 1 秒钟时, 这两个 点击动作被确定为不属于一个触屏输入。
需要说明的是, 在上述实施例中, 都是通过触屏输入点亮触摸屏的, 但本发明的实施例并不限于此, 通过触摸特定按键如电源键或 Home键等 的方式点亮触摸屏在上述实施例中同样适用。 具体地, 触摸屏熄灭的原因大概包括两类: 由于显示超时引起的熄灭 和用户通过按键手动将触摸屏熄灭。 较佳的, 对于这两种原因引起的触摸 屏熄灭, 可以采用不同的触摸屏点亮方法, 从而使用户操作更方便。
举例说明, 在本发明的一个实施例中, 在步骤 S11 之前, 所述方法还 可包括如下步骤:
确定所述触摸屏的熄灭原因;
如果所述原因为显示超时, 允许接收用户在触摸屏熄灭的状态下进行 的触屏输入;
如果所述原因为用户通过按键手动将触摸屏关闭, 禁止接收用户在触 摸屏熄灭的状态下进行的触屏输入。
图 3 示出了一部手机由触摸屏息灭到再次被点亮的过程中, 触摸屏点 亮方法的详细流程。 如图 3所示, 主要包括如下步骤:
11、 触摸屏熄灭, 等待用户输入点亮触摸屏的指令;
12、确定输入是按键输入还是触屏输入, 如果为按键输入执行步骤 13, 如果为触屏输入执行 15;
13、 确定输入的按键是否为电源键或 Home键, 如果是, 执行 14, 如 果否, 执行 17;
14、 点亮触摸屏;
15、 确定引起触摸屏的熄灭原因是否为显示超时, 如果是, 执行 16, 如果否, 执行 17;
16、 将触屏输入与预先设置的触屏操作相比较, 如果两者一致, 执行 14, 如果不一致, 执行 17;
17、 不响应, 返回 11。
本实施例将通过按键输入点亮触摸屏与通过触屏输入点亮触摸屏结合 起来, 使用户在不同的应用场景下选择合适的方式点亮触摸屏, 大大提升 了用户体验。 与前述的触摸屏点亮方法相对应, 如图 4所示, 本发明的实施例还提 供一种触摸屏点亮装置, 包括:
接收单元 21,配置为接收用户在触摸屏熄灭的状态下进行的触屏输入; 点亮单元 22,配置为当接收单元 21接收的所述触屏输入与预先设定的 触屏操作一致时, 点亮所述触摸屏。
本发明实施例提供的触摸屏点亮装置, 其接收单元 21能够在触摸屏熄 灭的状态下接收用户的触屏输入, 其点亮单元 22能够在触屏输入与预先设 定的触屏操作一致时, 将触摸屏点亮。 由于触摸屏面积较大, 很容易被用 户触碰到, 用户只需根据手与终端的相对位置就近在触摸屏上进行触屏输 入即可将触摸屏点亮。 这样就避免了用户忙乱之中寻找电源键或 Home键、 为了按下电源键或 Home键以点亮触摸屏而不得不改变终端握持姿势等等 不便, 有效地提升了用户体验。
优选的, 接收单元 21可具体配置为设置触摸屏芯片在所述触摸屏熄灭 后处于低功耗模式, 以从所述触摸屏芯片接收用户的触屏输入, 在所述低 功耗模式中, 所述触摸屏芯片的触屏输入管脚监听用户的触屏输入, 所述 管脚处于挂起状态。
可选的, 接收单元 21可以包括定时模块, 具体用于设置触摸屏芯片在 所述触摸屏熄灭后的规定时间内处于低功耗模式, 以在所述规定时间内从 所述触摸屏芯片接收用户的触屏输入。
可选的, 所述预先设定的触屏操作包括按照规定顺序、 以规定时间间 隔作用在所述触摸屏上的点击、 长按、 滑动操作中的至少一种。
可选的, 所述规定时间间隔可以为小于 1秒钟。
另外, 上述接收单元 21、 点亮单元 22均可由触摸屏点亮装置中的中央 控制器(也可称为中央处理器 (CPU, Central Processing Unit ) )来实现, 还可以由微处理器(MPU, Micro Processing Unit ),数字信号处理器(DSP, Digital Signal Processor )或可编程遝辑阵歹1 J ( FPGA, Field - Programmable Gate Array ) 实现。
优选地, 如图 5所示, 该触摸屏点亮装置还可包括: 比较单元 23, 用 于将接收单元 21接收的所述触屏输入与预先设定的触屏操作相比较。
可选的, 如图 6所示, 触摸屏点亮装置还可包括:
确定单元 24, 用于确定所述触摸屏的熄灭原因;
允许单元 25, 用于如果所述确定单元 24确定所述原因为显示超时, 允 许接收单元 21接收用户在触摸屏熄灭的状态下进行的触屏输入;
禁止单元 26,用于如果所述确定单元 24确定所述原因为用户通过按键 手动将触摸屏关闭, 禁止接收单元 21接收用户在触摸屏熄灭的状态下进行 的触屏输入。
另外, 上述比较单元 23、 确定单元 24、 允许单元 25、 禁止单元 26均 可由触摸屏点亮装置中的中央控制器(也可称为中央处理器(CPU, Central Processing Unit ) )来实现,还可以由微处理器( MPU, Micro Processing Unit )、 数字信号处理器( DSP, Digital Signal Processor )或可编程逻辑阵列( FPGA, Field - Programmable Gate Array ) 实现。
相应地, 本发明的实施例还提供一种移动终端, 该移动终端上设置有 前述实施例提供的任一种触摸屏点亮装置, 因此也能实现相应的有益技术 效果, 前文已经进行了详细的说明, 此处不再赘述。
尽管为示例目的, 已经公开了本发明的优选实施例, 本领域的技术人 员将意识到各种改进、 增加和取代也是可能的, 因此, 本发明的范围应当 不限于上述实施例。
