技术领域
本发明涉及通信设备技术领域，尤其涉及一种电子设备。
背景技术
随着技术的进步及电子设备的发展，用户对于全面屏电子设备的需求逐渐增加，全面屏也逐渐成为一种发展趋势。全面屏电子设备的发展使得一些功能模块被镶嵌在电子设备的内部，例如摄像模组、受话器和指纹识别模组等。
以摄像模组为例，通常情况下，为了不影响电子设备的屏幕占比，摄像模组设置在电子设备的内部，同时，为了使得摄像模组的拍摄效果较好，摄像模组能够在驱动机构的驱动下从电子设备的壳体的穿孔进出，从而发挥相应的功能。
但是，驱动机构主要有驱动电机和传动装置组成，驱动电机和传动装置由于结构比较复杂，因此体积相对较大，从而影响电子设备的内部空间布局，同时，由于传动装置一般为金属材料，从而使得驱动机构的整体质量较大，而且驱动电机工作时也会产生一定的噪音从而影响用户体验。
发明内容
本发明公开一种电子设备，以解决目前的摄像模组占用电子设备较大空间的问题。
为了解决上述问题，本发明采用下述技术方案：
一种电子设备，包括：
壳体；
液晶显示模组，所述液晶显示模组包括显示屏和背光模组，所述显示屏设置在所述壳体上，且与所述壳体形成内腔，所述背光模组设置在所述内腔中，所述显示屏与所述背光模组相连，所述背光模组开设有避让空间；
摄像模组，所述摄像模组设置在所述内腔中，至少部分所述摄像模组位于所述避让空间中，且所述摄像模组朝向所述显示屏，所述摄像模组包括摄像头组件、透光导光罩和补光灯，所述透光导光罩罩设在所述摄像头组件上，且所述透光导光罩的出光侧朝向所述显示屏，所述补光灯朝向所述透光导光罩设置。
本发明采用的技术方案能够达到以下有益效果：
相比于现有的电子设备，本发明实施例公开的电子设备中，当液晶显示模组工作、且摄像模组不启用拍摄功能时，还可以通过透光导光罩和补光灯使得摄像模组朝向液晶显示模组的区域也能够发光，进而使得液晶显示模组可显示的面积较大，从而能够增大电子设备的屏幕占比。
同时，本发明实施例公开的电子设备中，摄像模组无需通过驱动机构伸出到壳体之外来提升电子设备的屏幕占比，从而使得电子设备无需设置单独的驱动机构来驱动摄像模组，进而使得电子设备的内部空间不受驱动机构的限制，从而能够减小占用空间，同时，由于无需驱动机构，因此还能够使得电子设备的整体质量较小。

具体实施方式

以下结合附图，详细说明本发明各个实施例公开的技术方案。

壳体为电子设备的外围构件，壳体能够为电子设备上的其他构件提供安装位置。
液晶显示模组100包括显示屏110和背光模组120，显示屏110设置在壳体上，且与壳体形成电子设备的内腔，从而使得电子设备的大多数电子元器件可以设置内腔中。显示屏110用于电子设备显示图像及色彩等，背光模组120设置在电子设备的内腔中，显示屏110与背光模组120相连，背光模组120用于为显示屏110的显示提供补光，从而使得显示屏110能够正常显示图像及色彩。
摄像模组200设置在电子设备的内腔中，背光模组120开设有避让空间121，至少部分摄像模组200位于避让空间121中，同时，摄像模组200朝向显示屏110。此种方式下，摄像模组200在工作过程中，背光模组120将不影响摄像模组200的拍摄。避让空间121可以为避让槽，从而使得避让空间121可以被开设在背光模组120的外侧边缘，此种方式便于避让空间121的开设，同时，还能够使得至少部分位于避让空间121中的摄像模组200不影响电子设备的内部空间布局。
本发明实施例公开的电子设备中，摄像模组200包括摄像头组件210、透光导光罩220和补光灯230，在具体的装配过程中，透光导光罩220罩设在摄像头组件210上，同时，透光导光罩220的出光侧朝向显示屏110，补光灯230朝向透光导光罩220设置。
具体的工作过程中，当液晶显示模组100工作、且摄像模组200不启用拍摄功能时，补光灯230发光，从而使得光线照射到透光导光罩220上，照射到透光导光罩220上的光线通过透光导光罩220的导光作用，进而使得透光导光罩220的出光侧射出光线，从而使得光线能够对显示屏110上与避让空间121相对的区域进行光线的补充，最终使得液晶显示模组100可显示的区域面积增大。
通过上述工作过程可知，本发明实施例公开的电子设备中，通过将摄像模组200设置在电子设备的内腔中，从而能够提升电子设备的屏幕占比，同时，相比于现有的电子设备，本发明实施例公开的电子设备中，当液晶显示模组100工作、且摄像模组200不启用拍摄功能时，还可以通过透光导光罩220和补光灯230使得摄像模组200朝向液晶显示模组100的区域也能够发光，进而使得液晶显示模组100可显示的面积较大，从而能够增大电子设备的屏幕占比。
同时，本发明实施例公开的电子设备中，摄像模组200无需通过驱动机构伸出到壳体之外来提升电子设备的屏幕占比，从而使得电子设备无需设置单独的驱动机构来驱动摄像模组200，进而使得电子设备的内部空间不受驱动机构的限制，从而能够减小占用空间，同时，由于无需驱动机构，因此还能够使得电子设备的整体质量较小。
本发明公开的实施例中，透光导光罩220具有一定的透光功能，在摄像模组200的工作过程中，光线能够透过透光导光罩220进入摄像头组件210的镜头211中，从而使得摄像模组200能够实现拍摄功能。
在一种可选的方案中，透光导光罩220的出光侧可以开设有避让孔221，摄像头组件210的镜头211可以通过避让孔221朝向显示屏110。此种方式下，光线透过显示屏110之后可以直接照射在镜头211上，从而使得摄像模组200的成像效果较好。当然，避让孔221的大小可以与镜头211的大小相匹配， 从而防止在透光导光罩220的出光侧开设过大的避让孔221而影响透光导光罩220的出光效果。
当然，在此基础上，至少部分镜头211可以位于避让孔221中，从而使得透光导光罩220将不影响镜头211的安装位置，同时，此种方式还便于透光导光罩220的安装定位。
同时，为了使得避让孔221对透光导光罩220的出光侧的出光效果的影响较小，避让孔221的直径可以在向着靠近显示屏110方向递增，从而使得避让孔221的内侧表面相当于圆锥面221a。此种方式下，当液晶显示模组100工作、且摄像模组200不启用拍摄功能时，补光灯230发出光线，光线传播到透光导光罩220的出光侧，进一步地，部分光线通过圆锥面221a射出，从而照射到避让孔221朝向显示屏110的区域，进而使得透光导光罩220的出光侧包括避让孔221以内的区域均能够实现较好的出光效果，最终提高透光导光罩220的出光效果，同时，圆锥面221a还能够使得避让孔221所在的区域实现均匀出光的效果。
同样地，为了提升透光导光罩220在避让孔221所在区域的发光效果，避让孔221的内侧表面可以设置有多个第一散光波点221b，第一散光波点221b可以为凹面结构，具体可以通过激光雕刻成型。请参考图3，此种方式能够增强避让孔221的内侧表面的出光效果，同时，第一散光波点221b还能够使得避让孔221的内侧表面的各个位置出光较均衡，从而实现避让孔221的内侧表面的均匀亮光效果。在一种可选的方案中，避让孔221的内侧表面可以为圆锥面221a、且圆锥面221a可以设置有多个第一散光波点221b，从而更好的确保避让孔221所在区域的出光效果。
当然，为了使得透光导光罩220的出光侧能够产生均匀的亮光，透光导光罩220朝向显示屏110的内侧表面可以设置有多个第二散光波点222，第二散光波点222也可以为凹面结构，第二散光波点222使得透光导光罩220朝向显示屏110的内侧表面的区域能够实现均匀亮光的效果，进而使得液晶显示模组100可显示的面积较大。
进一步地，第一散光波点221b可以呈阵列分布，从而使得避让孔221的内侧表面的各个位置出光更均衡，进而使得避让孔221的内侧表面能够实现 均匀亮光效果，同理，第二散光波点222也可以呈阵列分布，从而使得透光导光罩220朝向显示屏110的内侧表面的区域能够实现均匀亮光的效果。相比于第二散光波点222的分布密度，第一散光波点221b的分布密度可以大于第二散光波点222的分布密度，此种方式下，可以进一步提升避让孔221所在的区域的发光效果，进而使得透光导光罩220的出光侧能够均匀发光。
摄像模组200具有电路板240，本发明公开的实施例中，电路板240不仅使得摄像模组200能够正常工作，同时，电路板240还能够为摄像模组200中的其他部件提供安装位置。在具体的装配过程中，摄像头组件210与电路板240电连接，与此同时，电路板240还可以包括延伸至摄像头组件210之外的外沿区域241，补光灯230可以设置在外沿区域241、且与电路板240电连接。当然，摄像模组200的其他部件也可以设置在外沿区域241上，从而使得摄像模组200的结构较紧凑。补光灯230设置在外沿区域241还能够使得补光灯230对透光导光罩220的发光效果较好。
为了使得补光灯230发出的光线能够较多的出射到透光导光罩220中，补光灯230可以设置在靠近透光导光罩220的位置，一种具体的实施方式中，透光导光罩220具有朝向电路板240的端口，且透光导光罩220具有围绕透光导光罩220的端口的端面，补光灯230可以设置在端面与电路板240之间。此种方式下，请参考图1(箭头指光线的方向)，补光灯230发出的光线可以直接照射到透光导光罩220的端面上，从而使得透光导光罩220中进入的光线较多，进而使得透光导光罩220的出光效果较好。
同样地，为了使得透光导光罩220的出光效果更好，补光灯230的数量可以为多个，多个补光灯230可以间隔分布，从而使得进入到透光导光罩220的光线较强，进而提升透光导光罩220的出光效果。当然，多个补光灯230可以围绕透光导光罩220朝向电路板240的端口设置，且多个补光灯230均可以设置在端口的端面与电路板240之间，从而能够进一步增强透光导光罩220的出光效果。
本发明实施例公开的电子设备中，摄像模组200还可以包括调光芯片250，调光芯片250可以与补光灯230相连，调光芯片250用于控制补光灯230的亮度和色温中的至少一者，从而在具体的工作过程中，调光芯片250使得补 光灯230能够根据工作所需而发出不同的亮度或色温，进而使得摄像模组200朝向显示屏110的区域能够更好的适应显示屏110的图像变化。
当然，为了使得摄像模组200的结构较紧凑，调光芯片250可以设置在电路板240的外沿区域241，且与电路板240电连接，此种方式还能够使得调光芯片250能够较好的控制补光灯230的亮度或色温。
本发明公开的实施例中，当摄像模组200启用拍摄功能时，补光灯230不工作，从而使得外界的光线能够透过显示屏110，进而照射到摄像模组200的镜头211上，最终使得摄像模组200实现拍摄功能。通常情况下，显示屏110包括上偏光片和下偏光片，上偏光片和下偏光片用于显示屏110的成像。上偏光片的两侧和下偏光片的两侧通常均具有偏光功能。
此种情况下，当摄像模组200启用拍摄功能时，外界的光线需要透过显示屏110，进而才能够照射到镜头211上。但是，外界的光线在透过显示屏110的过程中，由于上偏光片和下偏光片的偏光作用，外界的部分光线容易被上偏光片和下偏光片偏光，从而影响光线的透过率，进而影响摄像模组200的拍摄效果。
因此，为了使得上偏光片和下偏光片对摄像模组200的拍摄效果的影响较小，上偏光片可以为第一单向偏光片113，下偏光片可以为第二单向偏光片114。在具体的装配过程中，显示屏110包括第一玻璃111和第二玻璃112以及设置在第一玻璃111与第二玻璃112之间的液晶层，第一玻璃111与第二玻璃112相连，第一玻璃111背离所述第二玻璃112的表面可以设置有第一单向偏光片113，第二玻璃112背离第一玻璃111的表面可以设置有第二单向偏光片114。
基于此，在具体的工作过程中，第一单向偏光片113和第二单向偏光片114对透光导光罩220射入到显示屏110的光线能够进行偏光处理，此种方式下，液晶显示模组100能够正常工作；同时，由于第一单向偏光片113和第二单向偏光片114均为单向偏光，外界的光线在穿过第一单向偏光片113和第二单向偏光片114、且射向镜头211的过程中，第一单向偏光片113和第二单向偏光片114不会产生偏光作用，从而使得更多光线能够照射到镜头211上，进而使得摄像模组200的拍摄效果较好。同时，第一单向偏光片113和 第二单向偏光片114由于能够发挥单向偏光作用，因此能够对液晶显示模组100的显示进行偏光处理，从而不影响液晶显示模组100的正常显示。
同时，第一玻璃111和第二玻璃112之间可以预留出较大的间隙，从而使得补光灯230发出的光线的透过率较好，进而提升摄像模组200的出光效果。
本发明实施例公开的电子设备可以为智能手机、平板电脑、电子书阅读器、可穿戴设备等设备。当然，该电子设备也可以是其他设备，本发明实施例不限制电子设备的具体种类。
本发明上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本发明的实施例而已，并不用于限制本发明。对于本领域技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
