In order to clearly show the structure of the unlocking system, the components in FIG. 1 are not drawn in actual structure, and are only shown in schematic form. The unlocking system includes:
电源键 11 ;  Power button 11;
薄膜导电层 12， 该薄膜导电层 12内嵌在电源键 11的内部， 且该薄膜导 电层 12用于感知人体电场； 具体地， 该薄膜导电层 12可以与触摸屏手机中釆 用的用于实现触摸解锁功能的薄膜导电层具有相同的结构和功能，本实用新型 对此不作限定。本实用新型实施例中薄膜导电层可以釆用现有技术中常用的导 电材料制作而成。  The thin film conductive layer 12 is embedded in the interior of the power button 11, and the thin film conductive layer 12 is used to sense the electric field of the human body; specifically, the thin film conductive layer 12 can be used in a touch screen mobile phone for realizing The thin film conductive layer of the touch unlocking function has the same structure and function, which is not limited by the present invention. In the embodiment of the present invention, the thin film conductive layer can be made of a conductive material commonly used in the prior art.
PCB电路板（图中未示出）， 该薄膜导电层 12能够通过 PCB电路板 (图 中未示出）与便携设备中的控制芯片相连； 其中该控制芯片能够检测由于人体 电场影响而引起的电容或者电感的变化；  a PCB circuit board (not shown), the thin film conductive layer 12 being connectable to a control chip in a portable device through a PCB circuit board (not shown); wherein the control chip is capable of detecting an influence of a human body electric field a change in capacitance or inductance;
电源键支架 13， 用于将电源键 11固定到机壳 14上。  The power key holder 13 is for fixing the power key 11 to the casing 14.
当手机处于屏幕开启状态（本实用新型中， 手机处于屏幕开启状态即手机 屏幕处于 "亮" 的状态）时， 该解锁系统的工作原理如下： 由于薄膜导电层能 够感知人体电场， 当手指靠近内嵌有薄膜导电层的电源键时， 受人体电场的作 用， 手指与薄膜导电层之间会形成一个耦合电容或者耦合电感， 与薄膜导电层 相连的 PCB 电路板将该耦合电容或者耦合电感传至便携设备中的控制芯片； 控制芯片检测到由于手指触碰电源键导致内嵌到电源键内部的薄膜导电层的 电容或者电感的变化， 从而确定该触碰是用户的正确操作， 而不是误触， 进而 实现解锁。 其中， "手指靠近电源键" 是指手指与电源键之间的距离小于某一 固定值， 该固定值可以依薄膜导电层的结构、 尺寸、 所用材料等的不同而具体 设定， 本实用新型对此不作限定。 When the mobile phone is in the screen on state (in the present invention, when the mobile phone is in the screen on state, that is, the mobile phone screen is in the "light" state), the unlocking system works as follows: Since the thin film conductive layer can sense the human body electric field, when the finger is close to the inside When a power button with a thin film conductive layer is embedded, a coupling capacitor or a coupling inductor is formed between the finger and the thin film conductive layer by the electric field of the human body, and the coupling capacitor or the coupled inductor is transmitted to the PCB circuit board connected to the thin film conductive layer. a control chip in a portable device; the control chip detects a change in capacitance or inductance of a thin film conductive layer embedded inside the power key due to a finger touching the power key, thereby determining that the touch is a correct operation of the user, rather than a false touch , and then Achieve unlocking. Wherein, "the finger is close to the power button" means that the distance between the finger and the power button is less than a certain fixed value, and the fixed value can be specifically set according to the structure, the size, the material used, etc. of the conductive layer of the film, the utility model This is not limited.
当手机处于屏幕关闭状态（本实用新型中， 手机处于屏幕关闭状态即手机 屏幕处于 "暗" 的状态， 此时手机处于开机状态）时， 该解锁系统的工作原理 如下： 手指触碰电源键 (可以按下电源键或者滑动电源键或者以其他方式触碰 电源键）实现屏幕开启， 由于薄膜导电层能够感知人体电场， 当手指触碰该电 源键时， 受人体电场的作用， 手指与薄膜导电层之间会形成一个耦合电容或者 耦合电感， 与薄膜导电层相连的 PCB 电路板将该耦合电容或者耦合电感传至 便携设备中的控制芯片；控制芯片检测到由于手指触碰电源键导致内嵌到电源 键内部的薄膜导电层的电容或者电感的变化，从而确定该触碰是用户的正确操 作， 而不是误触， 进而实现解锁。 这样， 釆用一个步骤即可实现开启手机屏幕 并解锁的功能。  When the mobile phone is in the screen off state (in the present invention, when the mobile phone is in the screen off state, that is, the mobile phone screen is in a "dark" state, when the mobile phone is in the power-on state), the unlocking system works as follows: The finger touches the power button ( The screen can be turned on by pressing the power button or sliding the power button or otherwise touching the power button. Since the conductive layer of the film can sense the electric field of the human body, when the finger touches the power button, the finger and the film are electrically conductive. A coupling capacitor or a coupling inductor is formed between the layers, and the PCB circuit board connected to the conductive layer of the film transmits the coupling capacitor or the coupling inductor to the control chip in the portable device; the control chip detects the in-line embedded due to the finger touching the power button The change in the capacitance or inductance of the thin film conductive layer inside the power button determines that the touch is the correct operation of the user, rather than being accidentally touched, thereby unlocking. In this way, the function of turning on the screen of the mobile phone and unlocking can be realized in one step.
当手指按下或者滑动电源键时， 触发电源键， 产生中断， 唤醒手机上的控 制芯片 （该芯片能够检测电容或者电感的变化）。 控制芯片检测到由于手指靠 近薄膜导电层导致电源键内部的薄膜导电层的电容或者电感发生变化，从而确 定这是用户的正常动作， 不是误触。  When the finger is pressed or the power button is pressed, the power button is triggered to generate an interrupt and wake up the control chip on the phone (the chip can detect changes in capacitance or inductance). The control chip detects that the capacitance or inductance of the thin film conductive layer inside the power key changes due to the proximity of the finger to the thin film conductive layer, thereby determining that this is a normal operation of the user, not a false touch.
根据本实用新型实施例一提供的解锁系统，在电源键内部设置能够感知人 体电场的薄膜导电层，在电源键受到触碰并开启手机屏幕的同时、通过薄膜导 电层感知人体电场进而通过控制芯片判断该触碰是否直接来自于人体，如果是 则同时解锁。 以此， 用户能够通过触碰电源键实现开启手机屏幕和解锁两个功 能， 解锁过程简单并且解锁效率高。  According to the unlocking system provided by the first embodiment of the present invention, a thin film conductive layer capable of sensing an electric field of the human body is disposed inside the power key, and the power source key is touched and the screen of the mobile phone is turned on, and the electric field is sensed through the thin film conductive layer and then passed through the control chip.
