具体实施方式
以下结合附图对本公开的特征和原理进行详细说明，所举实施例仅用于解释本公开，并非以此限定本公开的保护范围。
针对相关技术中健康监控电路设置在屏幕的非显示区域，不利于全屏设计的技术问题，本公开实施例中提供了一种显示装置及数据监控方法，可以在实现实时监测使用者的健康指标等监测数据的同时，实现全面屏设计。
以下可选的说明本公开所提供的显示装置的实施例。
如图1至图6所示，本公开实施例所提供的显示装置包括：
显示面板100，包含显示区和围绕所述显示区的非显示区，所述显示面板包含设置在所述显示区内的多个发光单元；
触控电路200，与所述显示面板100电连接，所述触控电路200用于检测用户对所述显示面板100进行触摸的触控信息；
控制电路300，与所述触控电路及所述显示面板100电连接，响应于所述触控信息控制所述发光单元发射预定光线；
光感应电路400，与所述显示面板100和控制电路300电连接，用于感应所述预定光线并转换为电信号；以及
数据处理器500，与所述控制电路300和所述显示面板100电连接，用于对所述光感应电路400转换得到的电信号进行处理以得到监测数据，并通过所述显示面板100显示所述监测数据，
其中，所述触控电路200将所述触控信息发送至所述控制电路300。
上述触控信息可以包括用户在所述显示装置上的触摸位置、触摸开始时间、触摸结束时间等相关信息。此外，本公开中以用户通过手指触摸显示装置作为示例进行描述，但本申请所涉及的技术方案不限于此，用户通过任何部位或形式触摸显示装置的情况均可适用本申请的监控方法。
上述方案中，对应显示面板100的整个显示区域而全屏设置有光感应电路400，并利用显示面板100中的发光单元作为所述光感应电路400的感应光源(即，所述光感应电路400可感应显示面板100的发光单元所发出的光)，并且，利用触控电路200获取手指的触控位置等触控信息，这样，用户在使用过程中，手指触控到屏幕某一位置时，触控电路可将触控信息反馈至控制电路300，控制电路300驱动手指触控位置处的像素单元内的发光单元发光，所述光感应电路400即会感应到手指触控位置处的所述发光单元进行发光时所发出的光线，并转换为电信号，发送至数据处理器500，数据处理器500对所接收的电信号进行处理，而得到监测数据；当用户手指移开屏幕时，则触控电路会将通过手指移开的触控信息反馈至控制电路300，控制电路300将通过驱动芯片将解除手指触控位置处相应的所述发光单元停止发光，而使手指触控位置处的像素单元恢复之前的显示画面，从而不影响屏幕正常显示。
由此可见，本公开所提供的显示装置及数据监测方法，由于将光感应电路400是对应整个显示区域设置，并利用对应整个显示区域设置的触控电路200来获取手指触控信息，利用整个显示面板100的发光单元作为光感应电路400的感应光源，可以实现实时监控使用者的健康指标等监测数据的目的，且光感应电路、触控电路及发光单元均可全屏设计，无需单独封装于屏幕非显示区域，相较于相关技术单独将健康监控模块封装外贴于屏幕非显示区域的方式，可以实现全屏设计。
需要说明的是，上述方案中，所述显示面板100可以是OLED(Organic Light-Emitting Diode,有机发光二极管)显示面板，其中，所述发光单元可以包括阴极、阳极及位于阴极和阳极之间的发光层，所述发光层一般包括空穴注入层、空穴传输层、有机发光层、电子传输层和电子注入层等，所述控制电路300可通过控制所述阴极和所述阳极之间的电场，可驱动所述发光层进行发光。
在上述方案中，所述控制电路300可通过驱动芯片310来驱动手指触控位置处的所述像素单元内的所述发光单元进行发光，或者通过驱动芯片来驱动手指触控位置处的所述像素单元正常显示。
根据本公开的一些实施例，控制电路300可以构造为在接收到所述触控电路200发送的触控信息时，控制所述触控位置处的发光单元中断正常显示并发射所述预定光线，以及在触控结束时控制所述触控位置处的发光单元恢复正常显示。当然可以理解的是，所述显示面板100可不限于OLED显示面板，还可以是其他类型的显示面板，例如，所述显示面板100还可以是QLED(Quantum Dot Light Emitting Diodes，量子点发光二极管)显示面板或者AMOLED显示面板等。
此外，还需要说明的是，上述方案中，所述触控电路200可以包括触控层201和触控芯片202，所述触控层201可以贴合或者直接形成于显示面板100的出光侧一侧，用于在手指触控位置产生电容变化，所述触控芯片202用于将读取所述触控层的电容变化，并转化为触控信息反馈至所述控制电路300。
此外，在本公开实施例所提供的显示装置中，可选的，每一所述像素单元包括能够发出不同颜色光的多个子像素，例如，多个子像素包括第一子像素、第二子像素、第三子像素等，每一所述子像素对应设置一发光单元，各子像素所对应的发光单元可以为发出第一颜色光的第一发光单元、发出第二颜色光的第二发光单元和发出第三颜色光的第三发光单元等。例如，每一所述像素单元可以包括红、绿、蓝(RGB)三色子像素，或者，还可以包括红、绿、蓝、白(RGBW)四色子像素，每一子像素处对应设置有一发光单元。
可选的，所述控制电路300可通过驱动芯片301来控制所述像素单元内的发光单元进行发光或控制像素单元进行显示，所述控制电路300可以构造为，根据所述触控信息，驱动所述触控位置处的所述像素单元中发出第一颜色光的子像素所对应的第一发光单元发光；以及根据所述触控信息，控制所述触控位置处的像素单元中除所述发出所述第一颜色光的子像素之外的其他子像素所对应的发光单元不发光。
采用上述方案，所述光感应电路400可选的可感应第一颜色光，即，通 过对所述像素单元内的所述第一发光单元所发出的第一颜色光进行感应，来获取感应信号，因此，用户在使用过程中，手指触控到屏幕某一位置时，触控电路可将手指触控信息反馈至控制电路300，控制电路300驱动手指触控位置处的像素单元内的第一发光单元发出第一颜色光，而驱动手指触控位置处的像素单元内的其他颜色光关闭，这样，可以使得手指触控位置处只发出第一颜色光，防止其他颜色光的反射光干扰所述光感应电路400感应第一颜色光，增加数据监控的准确性。
可选的，所述第一颜色光为绿光。另外可选的，所述第一发光单元所发出的光线强度为固定强度。
采用上述方案，所述光感应电路400所能感应的光为绿光，且所述控制电路300驱动手指触控位置处的所述第一发光单元发出的绿光可以为固定强度，而所述光感应电路400只能接收到该固定强度的绿光，这样，用户的心跳频率等会使固定强度的绿光发生变化，以使得所述光感应电路400读取绿光的信号变化，而得到感应电信号，以保证监控数据的准确性。
需要说明的是，上述方案中，手指触控位置处至少有一个像素单元内的第一颜色光的强度是固定强度。
此外，应当可以理解的是，在实际应用中，当需要监测其他数据时，所述光感应电路400可根据实际需求设计为能够感应其他颜色光的光感应电路400，相应地，所述控制电路300可驱动手指触控位置处、所述光感应电路400所能感应颜色光的发光单元进行发光，而驱动其他颜色光关闭。
根据本公开的一些实施例，可以使用不同于单一发光单元发射的单一颜色光线，例如多个发光单元共同发光所得到的光线，来作为上述预定光线，并且通过光感应电路400来对该预定光线进行感应，以便获得用户触摸处对该预定光线的反射所提供的用户监测信息，例如反映用户健康状态的相关参数等。
可选的，如图6所示，所述光感应电路400包括：
多个光传感器401，每一所述光传感器401对应至少一个像素单元101设置；
以及，第一接收电路，用于接收控制参数，控制所述触控位置处的所述 光传感器401开启或关闭，所述控制参数包括：所述控制电路300根据所述触控信息所产生的控制参数、或者用户输入的控制参数。
采用上述方案，在所述显示面板100中，所述像素单元101呈阵列分布，所述光传感器401也可以呈阵列分布，且一个所述光传感器401可至少对应一个像素单元101设置，例如，图6中所示，一个光传感器401对应位于其四周的四个像素单元101设置，当然，在实际应用中，一个所述光传感器401可对应的像素单元101的数量不进行限定；并且，在上述方案中，所述光传感器401的开启或关闭可以是由所述控制电路300来控制(如图6所示在控制电路300与每一光传感器401之间设置有控制开关600)，所述控制电路300根据所述触控电路200的触控信息来控制所述光传感器401开启或关闭，具体地，当用户在使用过程中，手指触控到屏幕某一位置时，触控电路200可将手指触控信息反馈至控制电路300，控制电路300驱动手指触控位置处的所述光传感器401开启；当手指移开屏幕时，则触控电路200将手指移开的触控信息反馈至控制电路300，控制电路300驱动手指触控位置处的所述光传感器401关闭。这样，所述光感应电路可以不必一直处于开启状态，可以减少功耗。
当然可以理解的是，所述光传感器401也可以不受控制电路300的控制，一直处于工作状态，只是这样功耗会增加；或者，所述光传感器401还可以是通过用户输入的控制参数来控制其开启或关闭。
此外，如图2至图5所示，可选的，所述显示面板100可以包括：
衬底基板(图中未示意)；
形成于所述衬底基板上的驱动电路层110；
设置于所述驱动电路层110上的所述发光单元120；
及，封装所述发光单元120的封装层130；
其中，所述触控电路200的触控层201设置于所述封装层130之上；
所述光传感器401集成设置于所述驱动电路层120、或者所述光传感器401贴合于所述衬底基板的远离所述发光单元120的一侧。
采用上述方案，本公开实施例提供的显示装置的数据监测原理采用反光式光感应，即，发光单元发出的第一颜色光透过显示屏幕的显示面出射至用 户手指，所述光感应电路400感应经用户手指反射回的第一颜色光线，从而获取监测数据，因此，所述光感应电路400可以集成在衬底基板上的驱动电路层中(如图2至图4所示)，也可以贴合在整个显示面板100的屏幕背面(如图5所示)。
此外，可选的，如图3和图4所示，所述衬底基板上在与每一所述光传感器401所正对的位置处开设有透光孔402或者设置有透镜结构403。
采用上述方案，所述光感应电路400与所述发光单元的发光层之间可以不做任何特殊设计(如图2和图5所示)，还可以加入透光孔402(如图3所示)或者透镜结构403(如图4所示)，以消除杂散光的干涉。
此外，还需要说明的是，本公开实施例提供的显示装置，对于所述光传感器401的具体结构及大小等不进行限定，在手指与屏幕的接触面积内可以只有一个光传感器401，也可以有多个光传感器401。并且，可选的，发射固定强度的绿光的像素单元101总面积不超过手指与屏幕的接触面积，这样，可以保证用户在使用过程中所观看到的显示画面在手指触控位置处不会由于像素单元101仅发光而导致画面受到影响。
此外，需要说明的是，用户手指在手机等显示装置的使用过程中，很大一部分的时间内都是与屏幕接触，只是接触的位置会随着时间不断地变化，因此，在本公开实施例所提供的显示装置中，最终监控的数据结果是多组数据拟合得到的。具体地，所述数据处理器500包括：
第二接收电路，用于接收所述光感应电路400的电信号，所述电信号包括在不同时间段内所述光感应电路400所感应到的光线强度波形曲线；
数据整合电路，用于根据所述电信号，将不同时间段内所述光感应电路400所感应的光线强度波形曲线进行整合，得到所述监测数据。
采用上述方案，如图7和图8所示，用户在使用过程中，数据处理器500将得到不同时间段内一系列监测数据，数据处理器500通过这些原始的不同时间段内一系列监控数据进行拟合，计算可以得到最终需要的监测数据。
通常来讲，如图7所示，每一时刻段内所监测的监测数据可得到对应的一光线强度波形曲线，不同时刻的光线强度波形曲线的频率以及强度不会完全一致，因此，对于每一时间段内的光线强度波形曲线，只要截取其第一个 光线强度极值点(光线强度最低点)和最后一个光线强度极值点(光线强度最高点)之间的波形，再把所有时间段内的波形按照时间先后拼接整合在一起，即可得到完整的光线强度波形曲线(图8所示)。通过这个完整的光线波形曲线，便可得到用户的健康指标(如心跳频率等)监控数据。
其中，需要说明的是，对于时间段的时间长短，可以由所述显示装置在出厂时在***端设定好，也可以做出一些备选方案由用户自行选择设定。
需要说明的是，在实际应用中，所述数据处理器500对于所述电信号数据处理方式可以不仅局限于此，还可以采用其他方式，例如，也可以在获取每一时间段(位置1、位置2、位置3…位置n)的光线强度波形曲线时，就算出每一时间段内的一个子指标A1、A2、A3…An(例如，该子指标可以是每一时间段内的光线强度平均值)，再将各时间段内的子指标进行数据统计计算，得到用户的健康指标(如心跳频率等)监控数据。
此外，本公开实施例中还提供了一种数据监测方法，应用于本公开实施例所提供的显示装置，所述方法包括：
步骤S1、通过触控电路200检测用户对显示面板100进行触摸的触控信息，并且所述触控电路200将所述触控信息发送至控制电路300；
步骤S2、控制电路300响应于所述触控信息控制所述发光单元发射预定光线；
步骤S3、通过光感应电路400感应所述预定光线并转换为电信号。
可选的，该数据监测方法还包括：通过数据处理器500对所述光感应电路400转换得到的电信号进行处理以得到监测数据，并通过所述显示面板100显示所述监测数据。
上述方案中，对应显示面板100的整个显示区域而全屏设置有光感应电路400，并利用显示面板100中的发光单元作为所述光感应电路400的感应光源(即，所述光感应电路400可感应显示面板100的发光单元所发出的光)，并且，利用触控电路200获取手指的触控位置及触控时间等触控信息，这样，用户在使用过程中，手指触控到屏幕某一位置时，触控电路可将触控信息反馈至控制电路300，控制电路300驱动手指触控位置处的像素单元101内的 发光单元发光，所述光感应电路400即会感应到手指触控位置处的所述发光单元进行发光时所发出的光线，并转换为电信号，发送至数据处理器500，数据处理器500对所接收的电信号进行处理，而得到监测数据；当用户手指移开屏幕时，则触控电路会将通过手指移开的触控信息反馈至控制电路300，控制电路300将通过驱动芯片将解除手指触控位置处相应的所述发光单元停止发光，而使手指触控位置处的像素单元101恢复之前的显示画面，从而不影响屏幕正常显示。由此可见，本公开所提供的数据监测方法，可以实现实时监控使用者的健康指标等监测数据的目的，且相较于相关技术，可以实现显示装置的全屏设计。
可选的，所述方法中，所述步骤S2具体包括：
所述控制电路300根据所述触控信息，驱动所述触控位置处的所述像素单元101中发出第一颜色光的子像素所对应的第一发光层发光；控制所述触控位置处的像素单元101中除所述发出所述第一颜色光的子像素之外的其他子像素所对应的发光单元不发光。
采用上述方案，所述光感应电路400可选的可感应第一颜色光，即，通过对所述像素单元101内的所述第一发光单元所发出的第一颜色光进行感应，来获取感应信号，因此，用户在使用过程中，手指触控到屏幕某一位置时，触控电路可将手指触控信息反馈至控制电路300，控制电路300驱动手指触控位置处的像素单元101内的第一发光单元发出第一颜色光，而驱动手指触控位置处的像素单元101内的其他颜色光关闭，这样，可以使得手指触控位置处只发出第一颜色光，防止其他颜色光的反射光干扰所述光感应电路400感应第一颜色光，增加数据监控的准确性。
可选的，所述第一颜色光为绿光，此外，所述第一发光单元所发出的光线可以具有固定强度。
采用上述方案，所述光感应电路400设置为对绿光进行感应，且所述控制电路300驱动手指触控位置处的所述第一发光单元发出的绿光可以为固定强度，而所述光感应电路400只能接收到该固定强度的绿光，这样，用户的心跳频率等会使固定强度的绿光发生变化，以使得所述光感应电路400读取绿光的信号变化，而得到感应电信号，以保证监控数据的准确性。
需要说明的是，上述方案中，手指触控位置处至少有一个像素单元101内的第一颜色光的强度是固定强度。
此外，应当可以理解的是，在实际应用中，当需要监测其他数据时，所述光感应电路400可根据实际需求设计为能够感应其他颜色光的光感应电路400，相应地，所述控制电路300可驱动手指触控位置处、所述光感应电路400所能感应颜色光的发光单元进行发光，而驱动其他颜色光关闭。
可选的，所述步骤S3中，所述光感应电路400接收控制参数，控制所述触控位置处的光传感器401开启或关闭，所述控制参数包括：所述控制电路300根据所述触控信息所产生的控制参数、或者用户输入的控制参数。
采用上述方案，在所述显示面板100中，所述像素单元101呈阵列分布，所述光传感器401也可以呈阵列分布，且一个所述光传感器401可至少对应一个像素单元101设置，例如，图6中所示，一个光传感器401对应位于其四周的四个像素单元101设置，当然，在实际应用中，一个所述光传感器401可对应的像素单元101的数量不进行限定；并且，在上述方案中，所述光传感器401的开启或关闭可以是由所述控制电路300来控制，所述控制电路300根据所述触控电路200的触控信息来控制所述光传感器401开启或关闭，具体地，当用户在使用过程中，手指触控到屏幕某一位置时，触控电路可将手指触控信息反馈至控制电路300，控制电路300驱动手指触控位置处的所述光传感器401开启；当手指移开屏幕时，则触控电路将手指移开的触控信息反馈至控制电路300，控制电路300驱动手指触控位置处的所述光传感器401关闭。这样，所述光感应电路可以不必一直处于开启状态，可以减少功耗。
当然可以理解的是，所述光传感器401也可以不受控制电路300的控制，一直处于工作状态，只是这样功耗会增加；或者，所述光传感器401还可以是通过用户输入的控制参数来控制其开启或关闭。
可选的，所述步骤S4具体包括：
所述数据处理器500接收所述光感应电路400的电信号，所述电信号包括在不同时间段内所述光感应电路400所感应到的光线强度波形曲线；并根据所述电信号，将不同时间段内所述光感应电路400所感应的光线强度波形曲线进行整合，得到所述监测数据。
采用上述方案，如图7和图8所示，用户在使用过程中，数据处理器500将得到不同时间段内一系列监测数据，数据处理器500通过这些原始的不同时间段内一系列监控数据进行拟合，计算可以得到最终需要的监测数据。
通常来讲，每一时刻段内所监测的监测数据可得到对应的一光线强度波形曲线，不同时刻的光线强度波形曲线的频率以及强度不会完全一致，因此，对于每一时间段内的光线强度波形曲线，只要截取其第一个光线强度极值点(光线强度最低点)和最后一个光线强度极值点(光线强度最高点)之间的波形，再把所有时间段内的波形按照时间先后拼接整合在一起，即可得到完整的光线强度波形曲线。通过这个完整的光线波形曲线，便可得到用户的健康指标(如心跳频率等)监控数据。
其中，需要说明的是，对于时间段的时间长短，可以由所述显示装置在出厂时在***端设定好，也可以做出一些备选方案由用户自行选择设定。
需要说明的是，在实际应用中，所述数据处理器500对于所述电信号数据处理方式可以不仅局限于此，还可以采用其他方式，例如，也可以在获取每一时间段(位置1、位置2、位置3…位置n)的光线强度波形曲线时，就算出每一时间段内的一个子指标A1、A2、A3…An(例如，该子指标可以是每一时间段内的光线强度平均值)，再将各时间段内的子指标进行数据统计计算，得到用户的健康指标(如心跳频率等)监控数据。
以上所述为本公开较佳实施例，需要说明的是，对于本领域普通技术人员来说，在不脱离本公开所述原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本公开保护范围。
