Description

电子设备 技术领域
本实用新型涉及一种电子设备。
背景技术
随着智能手机的全面屏发展趋势，手机正面的屏占比越来越高，因此手机正面因为空间位置受限无法再设置其他组件，例如按键，指纹识别模组等。由于无法设置指纹识别模组，为了实现身份识别，业界提出了两种解决方案，第一种为现在相对比较成熟的技术，即将指纹识别模组放置于手机背面或侧面；第二种目前还处于理论研究阶段，即将指纹识别模组设置于显示屏内，例如放置于显示屏下方。
第二种解决方案虽然理论上能解决全面屏的身份识别问题，但是由于指纹识别模组位于显示屏的局部区域，使用者无法准确感知该区域，如此造成身份识别失败而使得手机无法解锁，因此影响使用者的使用。

进一步地，所描述的特征、结构可以以任何合适的方式结合在一个或更多实施方式中。在下面的描述中，提供许多具体细节从而给出对本实用新型的实施方式的充分理解。然而，本领域技术人员应意识到，没有所述特定细节中的一个或更多，或者采用其它的结构、组元等，也可以实践本实用新型的技术方案。在其它情况下，不详细示出或描述公知结构或者操作以避免模糊本实用新型。
本实用新型实施方式提出一种应用于屏内设有指纹识别模块的电子设备，且指纹识别模块的有效感测区域为电子设备的显示屏的局部显示区域。根据指纹识别模块在电子设备中的设置位置，在显示屏上设定一预定显示区域，该预定显示区域的部分或全部区域为指纹识别模块的有效感测区域。一旦检测到物体在该预定区域内滑动，则唤醒电子设备的指纹识别模块，从而使得指纹识别模块对预定区域内滑动的物体进行指纹信息的采集。
该电子设备例如但不局限为消费性电子产品、家居式电子产品、车载式电子产品、金融终端产品等合适类型的电子产品。其中，消费性电子产品如为手机、平板电脑、笔记本电脑、桌面显示器、电脑一体机等。家居式电子产品如为智能门锁、电视、冰箱、穿戴式设备等。车载式电子产品如为车载导航仪、车载DVD等。金融终端产品如为ATM机、自助办理业务的终端等。
在某些实施方式中，该电子设备例如包括显示装置、触摸传感模块以及指纹识别模块。该显示装置例如包括OLED显示屏、LCD显示屏以及驱动该显示屏进行显示的显示驱动电路等。触摸传感模块可以独立设置并位于显示屏的出光侧，当然，该触摸传感模块也可以集成于显示屏中，使得显示屏为具有触控和显示功能的触摸显示屏。指纹识别模块例如位于显示屏下方或上方，或者该指纹识别模块的部分或全部集成于显示屏内部，并且该指纹识别模块的有效识别区域为显示屏的部分区域。
指纹识别模块的有效感测区域与显示屏的预定区域对应，因此显示屏的预定区域对应指纹识别模块在电子设备中的设置位置来设置。具体地，如图1所示，图1是本实用新型第一实施方式的电子设备的正面结构示意图。需要说明的是，图1中，显示屏的预定区域S2位于显示屏的显示区域S1的中部靠下的位置。该预定区域S2的设置便于使用者单手拿着电子设备时，在显示屏上的滑动操作。再例如图2，图2是本实用新型第二实施方式的电子设备的正面结构示意图。该显示屏的预定区域S2位于显示屏的显示区域S1的靠右侧的位置。该预定区域S2的设置便于使用者双手拿着电子设备或单手拿 着电子设备时，在显示屏上进行滑动操作。需要说明的是，图1及图2中的虚线区域仅仅用来表示该区域的大小以及设置位置，在实际使用中不会进行显示。
进一步地，上述预定区域S2，可以根据电子设备的大小以及使用者的使用习惯等情况，设于显示区域S1的其他任意位置，例如顶部、上部、中部、下部或底部。
在某些实施方式中，该有效感测区域S3部分或全部覆盖显示屏的预定区域S2。具体地，在电子设备的厚度方向，有效感测区域S3的投影落于显示屏的预定滑动操作区域S2之中，或者有效感测区域S3的投影与显示屏的预定滑动操作区域S2重合。如图1和图2所示，该有效感测区域S3全部覆盖显示屏的预定区域S2，即有效感测区域S3的投影与显示屏的预定滑动操作区域S2重合，只要物体在该预定区域S2内滑动，均能采集到该物体的指纹信息。
在某些实施方式中，指纹识别模块的有效感测区域S3的面积为显示屏的显示区域的面积的三分之一以上、三分之二以下或一半以下。
参照图3，图3是本实用新型第三实施方式的电子设备的正面结构示意图。该指纹识别模块的有效感测区域S3覆盖显示屏的预定区域S2的部分区域，且该有效感测区域S3覆盖预定区域S2的一侧区域，例如预定区域S2的右侧区域。当物体在该预定区域S2内自左向右滑动，并滑动至预定区域S2的最右侧时，指纹识别模块则能采集到该物体的指纹信息。由于指纹识别模块的有效感测区域覆盖预定区域S2的局部区域，从而节省了指纹识别模块的设置成本。当然，可变更地，该指纹识别模块的有效感测区域S3覆盖预定区域S2的其他区域，例如预定区域S2的中部区域。
在某些实施方式中，指纹识别模块包括电容式传感器、超声波式传感器以及光学式传感器的一种或多种。以下将以光学式传感器举例，来介绍电子设备的屏内指纹识别结构的几种常见结构。
在某些实施方式中，指纹识别模块位于显示屏的预定区域的下方或上方，且沿电子设备的厚度方向，指纹识别模块有效感测区域的投影落于显示屏的预定区域之中，或者与显示屏的预定区域完全重合。参照图4，图4是图1中电子设备沿I-I线的第一实施方式的剖面结构示意图。该实施方式中的电子设备1例如包括显示屏20以及指纹识别模块10，该指纹识别模块10例如为一指纹传感芯片，并位于显示屏20下方。显示屏20包括多个显示像素21，该各个显示像素21的发光区域一起形成显示屏20的显示区域。指纹识别模块10包括多个感测单元11，该各个感测单元11的感测区域一起形成指纹识别模块10的有效感测区域。以光学式指纹识别为例，当手指放置于电子设备与物体的 接触面，即显示屏20上方时，该显示屏20的显示像素21发出的光信号将到达手指，经过手指的反射后，穿过显示屏20并到达指纹识别模块10，指纹识别模块10对光信号进行感测并形成指纹图像。可以理解的是，该显示屏20上具有透光区域，供手指反射回的信号穿过，例如OLED显示屏。
在某些实施方式中，指纹识别模块的部分或全部集成于显示屏内部，并且该指纹识别模块的有效感测区域为显示屏的预定区域的部分区域。参照图5，图5是图1中电子设备沿I-I线的另一实施方式的剖面结构示意图。该电子设备例如包括显示屏20以及指纹识别模块10。具体地，该显示屏20包括TFT阵列基板22，以及形成在TFT阵列基板22上的多个显示像素21。各个显示像素21的发光区域一起形成显示屏20的显示区域。该TFT阵列基板22上还设置多个感测单元11，而且该感测单元11设置于相邻的显示像素21之间。进一步地，若该感测单元11为光感测单元时，感测单元11两侧可设置遮光墙23，以防止显示像素21发出的光信号直接被感测单元11感测。各个感测单元11的感测区域一起形成指纹识别模块10的有效感测区域。以光学式指纹识别为例，当手指放置于显示屏20上方时，显示像素21发出的光信号到达手指后，经过手指的反射并到达感测单元11，感测单元11对光信号进行感测并形成指纹图像。
在某些实施方式中，在指纹识别模块进行指纹信息采集时，所述显示屏的预定区域点亮。点亮的预定区域不但用于提示使用者进行指纹输入时的操作位置，而且还用于提供光学式指纹识别时的光源，从而节省了额外设置指纹识别光源的成本。
在某些实施方式中，请参照图6，图6是本实用新型第四实施方式的电子设备的结构示意图。该电子设备除了包括指纹识别模块10、显示屏20之外，还包括触摸传感模块30。该触摸传感模块30位于显示屏20上，用于对显示屏20上的物体触摸操作进行检测。当然，可变更地，该触摸传感模块30也可以集成于显示屏20内，从而减小电子设备的厚度。进一步地，该触摸传感模块30例如包括电容式触摸屏、电阻式触摸屏等。
由于指纹识别模块位于显示屏的局部区域，因此，本实用新型实施方式中通过将指纹识别模块的有效感测区域与显示屏的预定区域对应，只要物体在该预定区域内滑动，与该预定区域对应的指纹识别模块就能对该触摸的物体进行指纹信息的采集。如此，不需要通过提示图标来提示使用者手指的触摸位置，即可实现指纹信息的采集。
上述电子设备处于息屏状态时，使用者通过在电子设备的预定显示区域内滑动来唤醒指纹识别功能，从而实现对电子设备的使用者进行身份识别，并在识别使用者的身份后解锁电子设备。以电子设备为移动终端举例，参照图7，图7是本实用新型一实施方 式的电子设备为移动终端的结构示意图。该移动终端100包括控制模块101、显示装置102、触摸传感模块103、指纹识别模块104。控制模块101用于当电子设备处于息屏状态时，判断显示装置102的预定区域内是否有物体滑动，当确定显示装置102的预定区域内有物体滑动时，控制指纹识别模块104启动，以进行指纹信息的采集。
需要说明的是，该移动终端100可以包括未组合或未包括在图7中所示部件中的其他部件(例如，通信电路、电源、总线、麦克风、摄像头等等)。而且，为了简洁，图7中仅示出了移动终端的部分部件。
具体地，息屏状态是指电子设备的显示屏处于熄灭状态，即未点亮状态。该息屏状态可以通过电子设备上的按键控制而进入，例如按压电子设备的电源键，可以使得电子设备进入息屏状态。当然，可替换地，当电子设备一段时间未被使用时，将自动进入息屏状态。当电子设备处于息屏状态时，将产生一息屏状态信号，控制模块101根据该息屏状态信号来判断电子设备是否处于息屏状态。控制模块101接收到该息屏状态信号时，产生第一驱动信号。该第一驱动信号用于提供给触摸传感模块103，以驱动触摸传感模块103执行触摸感测。根据触摸传感模块103的感测结果，判断物体是否在显示屏的预定区域内滑动。当确定物体在显示屏的预定区域内滑动时，产生第二驱动信号。该第二驱动信号用于提供给指纹识别模块104，以驱动指纹识别模块104采集指纹信息。
显示装置102包括显示屏，例如LCD显示屏、OLED显示屏，以及相应的显示驱动电路。控制模块101通过控制所述显示驱动电路，来驱动显示屏进行相应的显示。可以理解的是，若电子设备还包括图形控制模块GPU，则可先由图形控制模块GPU进行图形处理后，再通过显示驱动电路来驱动显示屏进行相应的显示。
触摸传感模块103在接收到控制模块101的第一驱动信号时，对显示屏进行触摸检测。具体地，控制模块101向触摸传感模块103提供第一驱动信号，以驱动触摸传感模块103的各触摸感测电极进行触摸检测，然后读取触摸传感模块103各触摸感测电极的检测信号，并根据读取到的检测信号，确定触摸操作类型以及触摸位置等信息。需要说明的是，该触摸传感模块103可以独立设置，也可以与显示屏集成为触摸显示屏。
指纹识别模块104例如包括光学式传感器、电容式传感器、超声波传感器。该指纹识别模块104根据第二驱动信号启动，并对预定区域内滑动的物体进行指纹信息的采集。具体地，该指纹识别模块104包括多个阵列排布的指纹感测单元，手指在预定区域内滑动时，位于手指正下方的指纹感测单元将采集到该手指的指纹信息。通过读取指纹识别模块104中各指纹感测单元采集到的指纹信息，对使用者进行身份识别。
本实用新型实施方式中，当确定物体在显示屏的预定区域内滑动时，则唤醒电子设备的指纹识别模块104。一旦指纹识别模块104被唤醒，就能采集到该手指的指纹信息，从而根据采集到的指纹信息对使用者进行身份识别，并在身份识别成功后，控制电子设备进行解锁操作。由于指纹识别模块的有效感测区域与显示屏上的预定滑动操作区域对应，因此不需要通过提示图标来提示指纹感知位置，只要使用者在预定滑动操作区域内滑动，即可实现指纹信息采集以及指纹识别，如此不但节省了电子设备的功耗，而且还避免了显示屏一直显示提示图标而造成显示屏的器件老化，进而影响显示屏的使用寿命。另外，通过滑动操作来唤醒指纹信息的采集，避免了使用者误触碰屏幕而造成的误操作。
为了更好地进行指纹信息的采集，物体在显示屏的预定区域内滑动并达到一定的时间(例如，0.5s)或距离(例如10mm)，以尽快唤醒指纹识别模块104，给指纹信息采集留出足够的时间。
在某些实施方式中，在显示屏的预定区域内滑动是指：滑动过程中，手指与显示屏的接触位置均位于预定区域内。也就是说，在滑动过程中，如果手指滑出了预定区域，则此处滑动为无效操作。如果显示屏在非预定区域滑动，则不属于本实用新型实施方式中的预定区域内的滑动操作。
在某些实施方式中，除了确定滑动过程中手指的触摸位置，还可以确定滑动过程中手指的滑动方向，若手指的滑动方向为预设的滑动方向，则唤醒指纹识别模块，以进行指纹信息的采集。
具体地，手指的滑动方向由手指的起始位置指向当前触摸位置的距离。如图8所示，图8是本实用新型一实施方式中确定物体在显示屏上的触摸滑动距离的示意图。图8中手指的滑动距离为起始位置O与当前触摸位置L的直线距离。根据图8中预定区域的设置位置以及形状大小，确定预设距离阈值，例如10mm、20mm。当确定手指的滑动距离后，将其与预设的距离阈值进行比较，当手指的滑动距离达到或超过预设的距离阈值时，唤醒指纹识别模块，否则不做指纹识别模块的唤醒处理。
在某些实施方式中，除了确定滑动过程中手指的触摸位置，还将确定手指的滑动方向。该滑动方向为手指起始位置指向当前触摸位置的方向。本实用新型实施方式中，预设一滑动方向，当手指的滑动方向与该预设的滑动方向匹配时，唤醒指纹识别模块，否则不做指纹识别模块的唤醒处理。可以理解的是，手指的滑动方向与预设的滑动方向匹配时，允许有一定的偏差，例如手指的滑动方向相对预设的滑动方向偏移5°时，也认为手指的滑动方向与预设的滑动方向匹配。
进一步地，电子设备当前处于息屏状态时，若确定物体在显示屏的预定区域内滑动时，则控制显示屏的预定区域点亮或者在物体与显示屏的触摸位置处点亮。此种情况主要用于光学式指纹识别，即利用显示屏点亮时发出的光信号进行指纹信息的采集，从而避免了额外设置光源进行指纹识别，节省了电子设备的成本。当然，也能应用于其他指纹识别，例如对用户的触摸操作进行响应的提示。
进一步地，上述控制模块101还用于：当确定物体在显示屏的预定区域内滑动时，控制显示屏的预定区域内显示滑动提示标识。该滑动提示标识用来指示使用者的滑动动作。例如图9a所示，该滑动提示标识为一箭头，用于指示使用者按箭头方向进行滑动，且滑动到箭头末尾。再例如图9b所示，该滑动提示标识为一个三角图案，用于指示使用者滑动结束的位置。如此，使用者的手指必须滑动到三角图案的位置处，才能实现指纹信息的准确、有效地采集。通过该滑动提示标识的显示，提示使用者准确进行滑动操作，从而指纹识别模块能准确地采集到指纹信息。当然，可以理解的是，该滑动提示标识还可以为其他图案以及其他位置。另外，该显示屏的其他区域可点亮，也可以不点亮。
进一步地，控制模块101还用于：当指纹识别模块在第一预定时间内未采集到指纹信息时，控制指纹识别模块104进入休眠状态。当指纹识别模块104在第一预定时间内未采集到指纹信息，则认为物体在显示屏的预定区域内的滑动操作都是使用者的误操作，此时将控制指纹识别模块104进入休眠状态。
进一步地，控制模块101还用于：当所述指纹识别模块104采集指纹信息并进行指纹验证成功时，控制电子设备解锁，并控制指纹识别模块104进入休眠状态。
当指纹识别模块采集到指纹信息并进行指纹验证成功时，为了不影响电子设备的正常触摸或触摸滑动操作，控制电子设备解锁的同时还控制指纹识别模块进入休眠状态。此时，即使使用者在显示屏的预定区域内进行触摸或触摸滑动操作，也不会进行指纹信息的采集。
进一步地，控制模块101还用于：根据触摸传感模块103的检测结果确定物体的触摸位置，并控制指纹识别模块104与触摸位置对应的指纹感测单元采集指纹信息。
具体地，参照图10，图10是本实用新型的指纹识别模块的线路结构示意图。该指纹识别模块104包括呈交叉排列的扫描线组和数据线组。例如多条扫描线沿G1、G2…Gm沿Y方向间隔布设；多条数据线S1、S2…Sn沿X方向间隔布设。然，可变更地，该多条数据线和多条扫描线不限定于图10中示出的垂直设置，也可以呈一定角度的设置，例如30°、60°等。交叉排列的多条扫描线和多条数据线界定出多个呈阵列排列的感测单 元11。
需要说明的是，上述扫描线组和数据线组的分布以及数量的设置并不局限于上述例举的实施方式，可以根据感测单元11的结构的不同而对应设置相应的扫描线组和数据线组。
参照图11，图11是图10中一个感光单元一实施方式的电路结构示意图。每个感测单元11包括至少一感光器件110和开关器件111。该开关器件111具有一控制端C以及两信号端。其中，开关器件111的控制端C与第二扫描线G2m连接，开关器件111的一信号端经感光器件110连接一参考信号L，开关器件111的另一信号端与第二数据线S2n连接。需要说明的是，图10示出的感测单元11仅用于举例说明，并不限于感测单元11的其他组成结构。
具体地，上述感光器件110例如但不限于光敏二极管、光敏三极管、光电二极管、光电阻、薄膜晶体管的任意一个或几个。以光电二极管为例，通过在光电二极管的两端施加负向电压，此时，若光电二极管接收到光信号时，将产生与光信号成一定比例关系的光电流，接收到的光信号强度越大，产生的光电流则越大，光电二极管负极上的电压下降的速度也就越快，因此通过采集光电二极管负极上的电压信号，从而获得目标物体不同部位反射的光信号强度，进而获得目标物体的生物特征信息。可以理解的是，若要增大感光器件110的感光效果，则设置多个感光器件110。
进一步地，开关器件111例如但不限于三极管、MOS管、薄膜晶体管中的任意一个或几个。当然，该开关器件111也可以包括其他类型的器件，数量也可以为2个、3个等。
多条扫描线均连接于一指纹驱动电路12，多条数据线均连接于一信号处理电路13。指纹驱动电路12用于在接收到控制模块101提供的第二驱动信号时，产生扫描信号，并通过对应的扫描线传输给相应的感测单元11，以驱动感测单元11执行光感测。信号处理电路13通过数据线接收相应的感测单元11执行光感测而产生的电信号，并根据该电信号来获取手指的指纹信息。该指纹驱动电路例如包括移位寄存器电路、时序控制电路等等。信号处理电路例如包括放大电路、比较电路等等。
需要说明的是，上述指纹识别模块104并不限于图中示出的结构，例如用于设置感测单元的衬底。其中上述指纹驱动电路12和信号处理电路13可选择形成在该衬底上，也可以选择例如通过连接件(例如柔性电路板)与扫描线、数据线电性连接。
进一步地，在控制指纹识别模块104采集指纹信息时，将根据触摸传感模块103的 检测结果确定物体的触摸位置，并通过扫描线、数据线的选择，驱动指纹识别模块104与触摸位置对应的指纹感测单元采集指纹信息以及指纹信息的读取。
在本说明书的描述中，参考术语“一个实施方式”、“某些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合所述实施方式或示例描述的具体特征、结构、材料或者特点包含于本实用新型的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
尽管上面已经示出和描述了本实用新型的实施方式，可以理解的是，上述实施方式是示例性的，不能理解为对本实用新型的限制，本领域的普通技术人员在本实用新型的范围内可以对上述实施方式进行变化、修改、替换和变型。
