本申请实施例提供一种电子装置，该电子装置可以包括电子设备等。
在一些实施例中，提供了一种电子设备。该电子设备可以是智能手机、平板电脑等设备。参考图1，电子设备100包括盖板10、传感器组件20、显示屏21、电路板30以及壳体40。
其中，盖板10安装到显示屏21上，以覆盖显示屏21。盖板10可以为透明玻璃盖板。在一些实施例中，盖板10可以是用诸如蓝宝石等材料制成的玻璃盖板。
显示屏21安装在壳体40上，以形成电子设备100的显示面。显示屏21作为电子设备100的前壳，与壳体40形成一封闭空间，用于容纳电子设备100的其他电子元件。同时，显示屏21形成电子设备100的显示面，用于显示图像、文本等信息。
电路板30安装在壳体40内部，以将电路板30收容在上述封闭空间内。电路板30可以为电子设备100的主板。电路板30上设置有接地点，以实现电路板30的接地。电路板30上可以集成有摄像头、处理器、传感器等功能组件。同时，传感器组件20可以电连接至电路板30。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接或可以相互通讯；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
在一些实施例中，电路板30上设置有显示控制电路。该显示控制电路向 传显示屏21输出电信号，以控制显示屏21显示信息。
壳体40用于形成电子设备100的外部轮廓。壳体40的材质可以为塑料或金属。壳体40可以一体成型。
在一些实施例中，显示屏21可以全屏显示。也即，显示屏21只包括显示区域，而不包括非显示区域，如图2所示。
在一些实施例中，如图3所示，传感器组件20包括环境光传感器22。其中，环境光传感器22设置在显示屏21的一侧。
可以理解的，环境光传感器22设置在显示屏21的内侧。其中，内侧指的是从电子设备100的外部观察时，显示屏21不可见的一侧。也即，环境光传感器22位于电子设备100内部。
其中，环境光传感器22用于检测或感应外界环境光信号，并将感应信息如环境光强度传输至电子设备100的处理器，处理器根据感应信息来控制显示屏21的亮度等。
比如，环境光传感器22检测到外界环境光信号变弱时，处理器可以提升显示屏21亮度，环境光传感器22检测到外界环境光信号变强时，处理器可以降低显示屏21亮度。
如图3所示，环境光传感器22设置在显示屏21的内侧，也即设置在显示屏21下方。
其中，壳体40的侧部400设置有感光孔401，外界环境光信号可以从感光孔401进入环境光传感器22。
在一些实施例中，壳体40的形状可以为圆角矩形等，该侧部400可以为壳体40的长侧部，也可也为壳体40的短侧部。其中，长侧部为壳体40侧边较长的侧部，短侧部为壳体40的侧边较短的侧部。
本申请实施例中，环境光传感器22可以通过侧部400的感光孔401感应外界环境光信号，相对于目前通过显示屏21感应外界环境光信号的方案，可以避免显示屏21自身亮度影响环境光信号的检测或感应，可以得到较为准确的感光信息，提升环境光传感器22的感光准确性，进而提升了显示屏21亮度的控制精确性。
在一些实施例中，感光孔401可以为电子设备100的壳体40侧部自带的开孔，比如，可以为包括：耳机插孔、USB插孔、扬声器的出声孔等壳体40侧部自带开孔中的一种。
例如，当感光孔401为USB插孔时，外界环境光信号可以通过USB插孔进入电子设备100的内部，从而被环境光传感器22感应，环境光传感器22可以将感应信息发送给处理器，处理器根据感应信息对显示屏21的亮度进行控制，如减低亮度或提升亮度。
本申请中，感光孔401的数量可以根据实际需求设定，比如，在一些实施例中，感光孔401的数量可以为2个、3个等等。
本申请中，感应孔401越大环境光传感器20感光效果越好，感光更精确。在受到电子设备100的尺寸限制下，在一些实施例中，感光孔401的直径在2至4毫米之间，感光效果最佳。
在一些实施例中，感光孔401的形状可以为多种，比如感光孔401可以为圆孔、方孔、椭圆孔等其他形状的孔。
在一些实施例中，参考图3，环境光传感器22可以具有感光面220，为提升环境光传感器的感光效果或准确性，该感光面220朝向感光孔401。比如，感光面220可以正对着感光孔401。
外界环境光信号可以从感光孔401射入感光面220，从而被环境光传感器22感应到。
在一些实施例中，为提升环境光传感器的感光效果或准确性，参考图4，还可以在壳体40设置聚光结构23；其中，聚光结构23设置在所述感光孔401与所述环境光传感器22之间，从所述感光孔401进入的环境光信号经过所述聚光结构23后进入所述环境光传感器22的感光面220。
其中，聚光结构23的作用是对外界环境光信号进行聚合，使得更多或者更强的外界环境光信号被环境光传感器22感应到。
在一些实施例中，聚光结构23可以包括光学透镜230等光学结构。
其中，光学透镜230可以是采用透光材料制作的透明镜片。例如，光学透镜230可以为透明玻璃镜片。在一些实施例中，如图5所示，光学透镜230 具有一凸面231和一平面232。其中，凸面231朝向环境光传感器22的感光面220。平面222朝向侧部400的感光孔401。
可以理解的，光学透镜230的凸面231朝向感光面220，从而光学透镜230可以起到聚光的作用。外界环境光信号可以更多地被传递到环境光传感器22，减少环境光信号在电子设备100内部的绕射或散射等，从而可以提高外界环境光信号的利用率，提高环境光传感器22的检测或感应准确性。
在一些实施例中，如图6所示，光学透镜230具有第一凸面233和第二凸面234。也即，光学透镜230为椭圆形镜片。光学透镜230的两面均为凸面。其中，第一凸面233朝向环境光传感器22的感光面220。第二凸面234朝向侧部400的感光孔401。
可以理解的，光学透镜230的两面均为凸面时，相对于光学透镜230的一面为凸面、另一面为平面而言，可以提高光学透镜230的聚光作用，进一步减少外界环境光信号在电子设备100内部的绕射或散射，使得更多地外界信号进入壳体40的内部，从而进一步提高环境光信号利用率，提高环境光传感器22的检测或感应准确性。
在一些实施例中，为了使得环境光传感器22可以在壳体40内部灵活设置，还可以在壳体40内设置或安装反射结构24，参考图7；其中，反射结构24设置在所述感光孔401与所述环境光传感器22之间，从所述感光孔401进入的环境光信号经过反射结构24反射后射入所述环境光传感器22。
比如，环境光传感器22可以设置在壳体40的靠近底部的位置，位于感光孔401与环境光传感器22之间的反射结构24可以从感光孔401进入的环境光信号反射到环境光传感器22，此时，靠近壳体40底部的环境光传感器22可以感应到从壳体40侧部感光孔401进入环境光信号。
其中，反射结构24可以包括反射镜片等具有光线反射功能的镜片。
由于将环境光传感器设置显示屏内侧，如果显示屏亮屏时，那么显示屏本身的亮度会影响光感的检测，此时显示屏亮屏时检测到的光感值实际上是要大于真实的外界光感值的，导致环境光传感器感光准确性较差。
本申请实施例可以在壳体40的侧部设置感光孔401，使得环境光传感器 22可以通过侧部的感光孔401感应外界环境光信号，避免了显示屏21的亮度对环境光感应或检测的影响，提升了环境光传感器感光准确性，以及显示屏21亮度控制的准确性。
在一些实施例中，参考图8，传感器组件20还可以包括接近传感器25，该接近传感器25与环境光传感器22设置在显示屏21的一侧，比如设置显示屏21的内侧。接近传感器25可以检测电子设备100与外界物体之间的距离，使得电子设备100可以基于距离控制显示屏21状态，如熄屏或亮屏等。
例如，在电子设备100通话时，电子设备100可以通过接近传感器25检测其与外界物体之间的距离，并基于距离控制显示屏21熄屏，或亮屏。如远离亮屏、接近时熄屏等。
在一些实施例中，参考图8，接近传感器25包括信号发射器251和信号接收器252。其中，信号发射器251用于向外发射探测信号A。探测信号A通过显示屏21传输到外界。探测信号A接触到外界物体200(例如，用户脸部)后，生成反射信号B。反射信号B通过显示屏21进入信号接收器252中。
信号接收器252接收到反射信号B后，可以将接收到的信号输出至电子设备100的处理器中进行处理，从而控制电子设备100的显示屏熄屏或者亮屏。
在一些实施例中，参考图8，信号发射器251具有信号发射面2510，信号发射面2510朝向所述显示屏21；信号接收器252具有信号接收面2520，信号接收面2520朝向所述显示屏21。
信号发射器251通过信号发射面2510向外发射探测信号A。探测信号A通过显示屏21传输到外界。探测信号A接触到外界物体200(例如，用户脸部)后，生成反射信号B。反射信号B通过显示屏21进入信号接收器252的信号接收面2520中。
在一些实施例中，为了减少接近传感器25与环境传感器22的相互干扰，参考图9，环境光传感22的感光面220分别与所述信号发射面2510、所述信号接收面2520垂直或者大致垂直。
在一些实施例中，所述信号发射器251为红外发射器，用于发射红外线。所述信号接收器252为红外接收器，用于接收红外线。
在一些实施例中，参考图10，显示屏21朝向环境光传感器22的一侧设置有遮光层210，遮光层210上设置有开孔213，信号发射器222a以及信号接收器222b位于开孔213下方。开孔213允许光信号、声波信号等信号通过。
在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
其中，信号发射器251用于向外发射探测信号A。探测信号A通过开孔213以及显示屏21传输到外界。探测信号A接触到外界物体200(例如，用户脸部)后，生成反射信号B。反射信号B通过开孔213以及显示屏21进入信号接收器252中。
在一些实施例中，遮光层210可以为泡棉或钢片等材料所制成的薄层结构。
在一些实施例中，所述开孔213为圆孔。所述开孔213的直径为2至4毫米。在其他一些实施例中，所述开孔213也可以为方孔、椭圆孔等其他形状的孔。
在一些实施例中，如图11所示，接近传感器25包括信号发射器251和信号接收器252。其中，信号发射器251和信号接收器252彼此相邻设置。信号发射器251的几何中心与信号接收器252的几何中心之间的距离d1为2至14毫米。
在一些实施例中，信号发射器251和信号接收器252封装成第一芯片24。信号发射器251和信号接收器252彼此相邻设置可以减小第一芯片24的体积。
在一些实施例中，如图12所示，接近传感器25包括信号发射器251和信号接收器252。其中，信号发射器251和信号接收器252彼此间隔设置。信号发射器251和信号接收器252之间的距离d2为2至14毫米。可以理解的，上述距离为信号发射器251的几何中心与信号接收器232的几何中心之间的距 离。信号发射器251和信号接收器252彼此间隔设置可以提高信号发射器251与信号接收器252之间的隔离度，减少信号发射器251发射的信号对信号接收器252造成的影响。
在一些实施例中，上述信号发射器251和信号接收器252封装成第一芯片24。
