技术领域
本公开涉及通信技术领域，尤其涉及一种移动终端。
背景技术
随着技术的发展进步，红外检测模块已经逐渐成为了智能手机等移动终端的标配之一，并可利用红外检测模块的测距功能丰富移动终端的功能，提升用户操作体验。比如，用户在进行电话通信的过程中，用户手持移动终端靠近耳朵时，红外检测模块可以检测到靠近动作，从而控制移动终端关闭触控屏，以防止耳朵误触发触控屏，影响用户通话。
目前，一般是在移动终端的盖板上设置红外发射通道及接收通道，以实现移动终端的红外检测功能。相关技术中，一般采用以下两种方案进行红外检测模块的设置，其一，在移动终端的盖板上设置两个导光孔分别用于发射红外光及接收红外光；其二，在移动终端的盖板上设置一个较大的导光孔以作为发射红外光和接收红外光的共同通道。上述两种方式均存在由于需要占用较大的布局空间而导致移动终端的屏占比较低的问题。
发明内容
本公开实施例提供一种移动终端，以解决相关技术中，具备红外检测模块的移动终端，存在屏占比较低的问题。
本公开实施例提供了一种移动终端，包括：显示模组、盖板、红外发射管以及红外接收管，所述显示模组与所述盖板层叠设置；所述红外发射管与所述显示模组连接，并通过所述显示模组向所述盖板方向射出红外光；所述红外接收管接收经外物反射的所述红外光。
这样通过将红外发射管设置在显示模组远离盖板的一侧，并在盖板上或者盖板与移动终端的壳体连接位置设置一个导光孔，作为接收红外光的通道；相对于相关技术中，需要在移动终端的盖板上设置两个导光孔分别用于发射红外光及接收红外光，或者需要在移动终端的盖板上设置一个较大的导光孔以作为发射红外光和接收红外光的共同通道；可以有效降低红外发射管及红外接收管在盖板一侧的布局空间，从而在一定程度上提升移动终端的屏占比，以满足移动终端高屏占比的发展趋势。
附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对本公开实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

图4是本公开实施例提供的发光组件的结构示意图之四。
具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
如图1至图4所示，本公开实施例提供一种移动终端，包括显示模组10、盖板20、红外发射管30以及红外接收管40，其中：
所述显示模组10与所述盖板20层叠设置；
所述红外发射管30与所述显示模组10连接，并通过所述显示模组10向所述盖板20方向射出红外光；
所述红外接收管40接收经外物反射的所述红外光。
本实施方式中，所述红外发射管30可以设于所述显示模组10远离所述盖板20的一侧，并与显示模组10连接，从而使红外发射管30射出的红外光能够从所述显示模组10的第一侧入射至所述显示模组10，并从所述显示模组10的第二侧射出，其中，所述显示模组10的第一侧为所述显示模组10远离所述盖板20的一侧，所述显示模组10的第二侧为所述显示模组朝向盖板10的一侧；通过这种结构设计，可以实现设置在所述显示模组10远离所述盖板20一侧的所述红外发射管30发射的红外光能够穿过所述显示模组10射出，并通过红外接收管40接收经外物(比如用户耳朵)反射的所述红外光，实现移动终端的红外检测功能。
这样通过将红外发射管设置在显示模组远离盖板的一侧，并在盖板上或者盖板与移动终端的壳体连接位置设置一个导光孔，作为接收红外光的通道；相对于相关技术中，需要在移动终端的盖板上设置两个导光孔分别用于发射红外光及接收红外光，或者需要在移动终端的盖板上设置一个较大的导光孔以作为发射红外光和接收红外光的共同通道；可以有效降低红外发射管及红外接收管在盖板一侧的布局空间，从而在一定程度上提升移动终端的屏占比，以满足移动终端高屏占比的发展趋势。
可选地，移动终端还可以包括一控制器(未图示)，所述控制器与所述显示模组10连接，用于控制显示模组10在第一状态与第二状态之间切换；
其中，所述第一状态为所述显示模组10处于能够使所述红外光透出所述显示模组10的状态，所述第二状态为所述显示模组10处于阻挡所述红外光透出所述显示模组10的状态。
本实施方式中，通过对显示模组10的状态进行控制，从而实现对移动终端的红外检测功能的控制，并只有当显示模组10处于第一状态时，红外发射管30发射的红外光才能透出显示模组10，并实现红外检测功能。可选地，显示模组10处于第一状态时，所述红外发射管30发射所述红外光，显示模组10处于第二状态时，所述红外发射管30停止发射所述红外光；相对于显示模组10处于第二状态，红外发射管30也一直发射所述红外光，可以降低红外发射管30的功耗。
可选地，如图3所示，所述显示模组10包括依次层叠设置的液晶层11、 导光板12和反射板13，所述液晶层11位于所述反射板13与所述盖板20之间，所述红外发射管30与所述导光板12连接。所述红外发射管30发射的红外光入射方向可与所述显示模组10所在平面平行。
本实施方式中，通过将红外发射管30与导光板12连接，导光板12可以使红外发射管30发射的红外光能够从液晶层11的一端导向另一端，从而使液晶层11朝向导光板12的一侧均匀分布红外发射管30射出的红外光，并在导光板12远离液晶层11的一侧设置反射板13，可以将射向反射板13的红外光，反射至液晶层11，以降低红外发射管30射出的红外光在传播过程中的损耗。
其中，如图4所示，红外发射管30可以与显示模组10的发光源14并行设置，通过设置红外发射管30与发光源14共用一个模组，可以节省红外发射管30的安装空间。
可选地，所述显示模组10的发光源14的数量为至少两个，且所述红外发射管30位于至少两个所述发光源14之间。
进一步地，所述红外发射管30正对所述导光板12的入光面的中间位置设置，这样可以进一步降低红外光在传播过程中的损耗。
可选地，所述盖板20包括透光区域和非透光区域，所述透光区域为所述盖板20与所述显示模组10对应的区域，所述非透光区域为所述盖板20上除所述透光区域之外的区域。
所述红外接收管40对应所述非透光区域设置于所述盖板20的内侧，且所述移动终端设有与所述红外接收管40对应的透光部，所述红外接收管40能够接收自所述透光部射入的所述红外光。
本实施方式中，盖板20可以是玻璃盖板，盖板20的非透光区域，可以通过在盖板20朝向显示模组10的一侧设置不透光的油墨层或者金属镀层，油墨层或者金属镀层的颜色可以是白色或者黑色。其中，考虑到生产成本的问题，优选为设置不透光的油墨层。
通过在移动终端上设置与红外接收管40对应的透光部，从而使红外接收管40能够接收自透光部射入的红外光，从而实现移动终端红外检测功能。
相对于相关技术中，需要在移动终端的盖板上设置两个导光孔分别用于 发射红外光及接收红外光，或者需要在移动终端的盖板上设置一个较大的导光孔以作为发射红外光和接收红外光的共同通道；可以有效降低红外发射管及红外接收管在盖板一侧的布局空间，从而在一定程度上提升移动终端的屏占比，以满足移动终端高屏占比的发展趋势。
其中，透光部可以设置在盖板20上，比如在盖板20的非透光区域，对应红外接收管40的位置，预留一个小孔或者缝隙，使红外光能够透过该小孔或者缝隙射向红外接收管40，从而使从显示模组10射出的红外光可以被红外接收管40接收，以实现移动终端的红外检测功能。
透光部还可以设置在盖板20的侧缘与移动终端的中框壳体连接的位置，相对于在盖板20的非透光区域设置透光部，可以进一步节省红外接收管40的布局空间，并提升移动终端的屏占比。
这样，通过上述结构设计，可以有效降低红外发射管及红外接收管在盖板一侧的布局空间，从而在一定程度上提升移动终端的屏占比，以满足移动终端高屏占比的发展趋势。
需要说明的是，本公开实施例提供的移动终端可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等等。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以权利要求的保护范围为准。
