下面分别对指纹识别传感器260和光传感器270的排布方式进行介绍。
第一，指纹识别传感器260的排布方式。
例如，各个指纹识别传感器260可设置于下玻璃基板221的上表面；再例如，各个指纹识别传感器260也可设置于液晶层230与上玻璃基板211相邻的一面；再例如，各个指纹识别传感器260还可设置于CF212上，等等。
如图6所示，其示出了指纹识别传感器260的第一种排布方式的示意图，其中，每个指纹识别传感器260通过对应的使能线261电性连接至控制芯片280，且每个指纹识别传感器260通过开关262与数据线263电性相连，数据线263用于传输采集到的指纹数据。图中，黑色矩形为指纹识别传感器260，横线为使能线261，竖线为数据线263。
在初始化时，控制所有的指纹识别传感器260处于空闲状态，等待扫描指令。即，每个指纹识别传感器260的使能端与对应的使能线261电性相连，通过在使能线261上传输的信号控制指纹识别传感器260是否与数据线263电性相连。图中，每个指纹识别传感器260通过一个开关262连接到对应的使能线261，且未与数据线263相连。
本实施例中，当控制芯片280通过使能线261控制指纹识别传感器260的开关262处于第一状态时，指纹识别传感器260处于空闲状态；当控制芯片280通过使能线261控制 指纹识别传感器260的开关262处于第二状态时，指纹识别传感器260处于工作状态。其中，第一状态为打开状态，第二状态为关闭状态；或者，第一状态为关闭状态，第二状态为打开状态，本实施例不作限定。
如图7所示，其示出了指纹识别传感器260的第二种排布方式的示意图，假设电子设备需要控制第二行的指纹识别传感器260进行指纹识别，则可以通过在使能线261上传输信号控制第二行的各个指纹识别传感器260与数据线263电性相连。
在指纹识别传感器260与数据线263电性相连后，电子设备通过扫描指令控制这些指纹识别传感器260进行扫描，得到指纹数据，并通过数据线263传输这些指纹数据，以便进行指纹识别处理。其中，当指纹识别传感器260为电容式指纹识别传感器时，指纹数据为电容值。
可选地，当指纹识别传感器260的数量为多个时，例如当指纹识别传感器260为n(n≥2)个时，该n个指纹识别传感器260均匀且分散地排布。例如，在图6中，各个指纹识别传感器260均匀且分散地排布于下玻璃基板221上。通过设置多个指纹识别传感器260，并将该多个指纹识别传感器260均匀且分散地排布，可以避免用户手指操作的位置没有排布指纹识别传感器导致指纹识别失败的问题，可以提高指纹识别的成功率。
在一种可能的实现方式中，如图5所示，各个指纹识别传感器260设置于下玻璃基板221的第二黑色矩阵223上；或者，各个指纹识别传感器260设置于CF212上的第一黑色矩阵212b上。例如，当光传感器270为多个时，该多个光传感器270均匀且分散地排布于第二黑色矩阵223上；或者，该多个光传感器270均匀且分散地排布于第一黑色矩阵212b上。通过将指纹识别传感器260设置在第二黑色矩阵223或第一黑色矩阵212b上，可以确保指纹识别传感器260的设置不会干扰到LCD面板的透光率，进而确保LCD面板的显示效果不受影响。
可选地，结合参考图6和图7，使能线261和数据线263设置于第二黑色矩阵223上。通过将使能线261和数据线263设置在第二黑色矩阵223上，可以确保使能线261和数据线263的设置不会干扰到LCD面板的透光率，进而确保LCD面板的显示效果不受影响。可选地，导线290也可以由透明材料制成。
第二，光传感器270的排布方式。
例如，各个光传感器270可设置于下玻璃基板221的上表面；再例如，各个光传感器270也可设置于液晶层230与上玻璃基板211相邻的一面；再例如，各个光传感器270还可设置于CF212上，等等。每一个光传感器270分别与控制芯片280电性相连。光传感器270 用于将光信号转换为电信号后提供给控制芯片280。
可选地，当光传感器270的数量为多个时，例如当光传感器270为m(m≥2)个时，该m个光传感器270均匀且分散地排布。例如，在图4中，各个光传感器270均匀且分散地排布于CF212上；或者，各个光传感器270均匀且分散地排布于下玻璃基板221的第二黑色矩阵223。通过设置多个光传感器270，并将该多个光传感器270均匀且分散地排布，可以避免因用户在LCD面板上操作而导致所有光传感器270全部被用户手指或其它物体遮挡，使得即使有部分光传感器270被遮挡时仍然有另一部分光传感器270未被遮挡，该另一部分未被遮挡的光传感器270仍然能够采集到准确的传感器数据。并且，通过将光传感器270设置在第二黑色矩阵223或第一黑色矩阵212b上，可以确保光传感器270的设置不会干扰到LCD面板的透光率，进而确保LCD面板的显示效果不受影响。
可选地，结合参考图4，每个光传感器270通过导线电性连接至控制芯片280，各条导线290也设置于CF212的第一黑色矩阵212b上。通过将导线290也设置在第一黑色矩阵212b上，可以确保导线290的设置不会干扰到LCD面板的透光率，进而确保LCD面板的显示效果不受影响。可选地，导线290也可以由透明材料制成。
可选的，光传感器270还可以均匀且分散地排布于触摸屏100上。
另外，每一个光传感器270包括光敏元件，该光敏元件朝向上偏光片240一侧设置，确保正常接收光信号。光敏元件包括但不限于光敏电阻、光敏二极管、光敏三极管、硅光电池中的任意一种。光敏元件用于将光信号转换为电信号。可选地，光敏元件可以由透明材料制成。
如图2所示，该液晶显示组件还可包括：至少一个背光源300。该至少一个背光源300与控制芯片280电性相连。背光源300设置于下偏光片250的背面。背光源300用于在LCD面板背后提供光源。背光源300的类型包括但不限于EL(Electro Luminescent，电致发光)、CCFL(Cold Cathode Fluorescent Lamp，冷阴极荧光灯管)、LED(Light Emitting Diode，发光二极管)等类型中的任意一种。
另外，控制芯片280可以是MCU(Microcontroller Unit，微控制单元)，MCU也称为单片微型计算机或者单片机，是一种芯片级的计算机。在一种可能的实现方式中，以MCU根据环境光亮度动态调整背光亮度为例，各个光传感器270采集环境光亮度，MCU从各个光传感器270获取环境光亮度，对获取的环境光亮度进行计算处理，并根据计算处理结果确定背光亮度，然后根据所确定的背光亮度控制背光源300发光。例如，当环境光亮度较大时，控制背光源300的发光亮度也较大；当环境光亮度较小时，控制背光源300的发光亮 度也较小。
另外，液晶显示组件所对应的显示区域可以是一个完整的显示区域，该显示区域对应设置有至少一个背光源300。各个背光源300用于控制整个显示区域的背光亮度。
或者，可选地，如图8所示，液晶显示组件所对应的显示区域81被划分为m(m≥2)个显示区块(如图示的第一显示区块82、第二显示区块83、第三显示区块84以及第四显示区块85)，每一个显示区块对应设置有至少一个背光源300，且每一个显示区块对应设置有至少一个光传感器270和至少一个指纹识别传感器260。对于每一个显示区块，其所对应的若干个背光源300用于单独控制该显示区块的背光亮度。例如，假设第一显示区块82对应设置有第一背光源和第一光传感器，第二显示区块83对应设置有第二背光源和第二光传感器，则第一背光源用于根据第一光传感器采集的环境光亮度单独控制第一显示区块82的背光亮度，第二背光源用于根据第二光传感器采集的环境光亮度单独控制第二显示区块83的背光亮度。通过将LCD面板所对应的显示区域划分为多个显示区块，并利用不同的背光源对该多个显示区块的背光亮度进行分区控制，提高了背光控制的灵活性。
综上所述，本发明提供的液晶显示组件，通过在上偏光片和所述下偏光片之间设置至少一个指纹识别传感器，且在上偏光片和所述下偏光片之间或在触摸屏上设置至少一个光传感器，可以根据光传感器选择部分指纹识别传感器进行指纹识别，解决了控制整个液晶显示屏上的所有指纹识别传感器进行指纹识别造成资源浪费的问题，达到了节省资源的效果。
另外，通过将指纹识别传感器和光传感器设置于CF的第一黑色矩阵上，或者，将指纹识别传感器和光传感器设置于下基板上设置的第二黑色矩阵上，确保指纹识别传感器和光传感器的设置不会干扰到LCD面板的透光率，进而确保LCD面板的显示效果不受影响。
另外，通过设置多个指纹识别传感器，并将该多个指纹识别传感器均匀且分散地排布，可以避免用户手指操作的位置没有排布指纹识别传感器导致指纹识别失败的问题，可以提高指纹识别的成功率。
另外，还通过设置多个光传感器，并将该多个光传感器均匀且分散地排布，可以避免因用户在LCD面板上操作而导致所有光传感器全部被用户手指或其它物体遮挡，使得即使有部分光传感器被遮挡时仍然有另一部分光传感器未被遮挡，该另一部分未被遮挡的光传感器仍然能够采集到准确的传感器数据。
根据本发明的另一实施例，还提供了一种电子设备。例如，该电子设备可以是移动电 话，计算机，数字广播终端，消息收发设备，游戏控制台，平板设备，医疗设备，健身设备，个人数字助理等。该电子设备包括如上述图1或图2所示实施例提供的液晶显示组件。
本领域技术人员在考虑说明书及实践这里的公开后，将容易想到本发明的其它实施方案。本申请旨在涵盖本发明的任何变型、用途或者适应性变化，这些变型、用途或者适应性变化遵循本发明的一般性原理并包括本发明未公开的本技术领域中的公知常识或惯用技术手段。说明书和实施例仅被视为示例性的，本发明的真正范围和精神由下面的权利要求指出。
应当理解的是，本发明并不局限于上面已经描述并在附图中示出的精确结构，并且可以在不脱离其范围进行各种修改和改变。本发明的范围仅由所附的权利要求来限制。
