随着科技的发展和进步，通信技术飞速发展并取得了长足的进步，而随着通信技术的提高，智能电子产品得到广泛的普及，智能终端或移动终端成为人们生活中不可或缺的一部分，智能终端包括智能手机、智能电视和电脑等。在移动终端普及的同时，多种类型的移动终端得到了不同用户的喜欢，多种类型的移动终端如大屏移动终端(如具有大于5.5英寸的显示屏幕的移动终端)和双屏移动终端等。
双屏移动终端是功能机时代的翻盖机的衍变，双屏移动终端不但要实现双屏闭合状态下移动终端的两面都是屏幕，还要求打开状态时两个屏幕距离很近，两块屏幕可以分别显示一幅图像的两部分。
相关技术中的双屏移动终端中，两个显示屏分别使用各自的背光源，但即使是两个相同规格的显示屏，由于多种原因也可能导致背光源的亮度有一定的差别，所以当两块显示屏合并在一起并分别显示同一个显示画面的两部分时，两块显示屏的亮度不一致可能比较明显，降低了用户体验。

下面将结合实施例中的附图，对实施例中的技术方案进行描述。
请参阅图13，图1为本实施例提供的移动终端处于第一状态的立体图，图2为图1中所示的移动终端处于第二状态的立体图。图3为图1中所示的移动终端的侧视图。本实施例提供的移动终端100包括两个显示屏10和两个连通窗120。所述两个显示屏10通过转轴20可转动连接。每个显示屏10还包括一显示区101及围绕所述显示区101的周边区102，所述显示区101用于实现每个显示屏的显示功能。
本实施例的移动终端100可以具有两个使用状态，当所述移动终端100处于第一状态时，两个显示屏10的背面相对设置，如图1所示。当所示移动终端100处于第二状态时，其中一个显示屏10可以通过连接两个显示屏10的转轴20进行翻转，使得两个显示屏的显示面处于同一平面，如图2所示。其中，所述移动终端100中，每个显示屏10可单独使用，也可以同时使用。
每个显示屏10包括外壳110及收容于所述外壳110内的背光模组170(如图4所示)，每个显示屏10的所述外壳110的第一侧边111上设置有连通窗120，所述两个显示屏中的一个显示屏的第一侧边与所述两个显示屏中的另一显示屏的第一侧边通过转轴20对接，第一侧边111上还可以设置有用于控制所述连通窗120的复位柱130。
可选的，所述连通窗120位于所述第一侧边111的中心，所述连通窗120与每个所述显示屏10的背光模组170的位置相对应，所述复位柱130位于所述连通窗120沿转轴20方向的两侧，所述第一侧边111上与所述复位柱130对应的位置设置有贯穿孔1111(图4中示)。当所述移动终端100处于第一状态时， 所述复位柱130穿过所述贯穿孔1111并伸出所述外壳110。
当所述移动终端100处于第二状态时，即所述两个显示屏10的显示面通过翻转处于同一平面时，每个显示屏10的第一侧边上的所述连通窗120打开，收容于两个显示屏100中的两个背光模组170相互连通形成一个公共背光模组，两个显示屏共用所述公共背光模组，此时，另一显示屏10的第一侧边111向所述复位柱130施加压力，使得所述复位柱130收回到所述外壳110中。
图4为图1中IV-IV处所示部分剖面的放大图，图5为图1中V-V处所示部分剖面的放大图。如图4和图5所示，每个显示屏10还可以包括遮光板140、第一连接件150、第二连接件160、背光模组170以及显示面板180。所述遮光板140、所述第一连接件150、所述第二连接件160、所述背光模组170和所述显示面板180可以收容于所述外壳110中。
可选的，所述遮光板140与所述连通窗120对应设置，所述遮光板140与所述第一侧边111平行且位于所述第一侧边111的内侧，所述遮光板140的面积大于所述连通窗120的面积，以使得所述遮光板140可以完全遮挡住所述连通窗120。
所述遮光板140上还可以设置有与所述第一侧边111上的贯穿孔1111相对应设置的通孔141，所述通孔141与所述贯穿孔1111连通，供所述复位柱130穿过的通孔141及所述贯穿孔，复位柱130伸出所述外壳110。
所述第一连接件150可以设置于所述显示屏10中，所述第一连接件150的第一端固定于所述外壳110的内壁上，即沿与所述第一侧边111相垂直的方向上，第一连接件150的第一端延伸至顶壁112上，所述第一连接件150的第二端与所述遮光板140连接。所述第一连接件150可以为具有弹性的连接件。可选的，本实施方式中，所述第一连接件150可以为弹簧。
所述外壳110的顶壁112朝向与所述顶壁112相对设置的底壁的一侧凸设有安装板113，所述安装板113与所述第一侧边111平行，所述安装板113对应位于所述显示屏10沿所述转轴20的轴向方向的两端的周边区内，所述安装板113、所述第一侧边111及所述顶壁112共同围成与U形槽，所述第一连接件150及所述遮光板140位于所述U形槽中。
所述安装板113靠近所述U形槽的一侧设置有安装槽1131，所述第二连接件160收容于所述安装槽1131中，且所述第二连接件160的第一端固定于所述 安装槽1131的底面上，所述第二连接件160的第二端与所述复位柱130连接。所述第二连接件160可以为具有弹性的连接件。可选的，本实施方式中，所述第二连接件160可以为弹簧。
所述复位柱130的一端可与所述第二连接件160连接，所述复位柱130与所述第二连接件160连接的一端收容于所述安装槽1131中，并可随着所述第二连接件160在所述安装槽1131内移动，所述复位柱130未与所述第二连接件160连接的一端可穿过所述通孔141及所述贯穿孔1111，从而伸出所述外壳110，所述复位柱130可伸出所述外壳110的一端可以设置有一向所述外壳110内部并向下倾斜的切面131，所述切面131的尖端向外延伸形成一顶柱132，以保证在两个显示屏合并的时候，即所述两个显示屏10的显示面通过翻转处于同一平面时，所述复位柱130可以被与该复位柱130相对的第一侧边挤压，使得复位柱130可以收回所述外壳110中。
所述背光模组170可与所述显示面板180层叠设置，所述背光模组170可以包括反光片171、导光板172、光学膜片组173及光源(图未示)，所述光学膜片组173位于所述导光板172与所述显示面板180之间，所述导光板172位于所述光学膜片组173与所述反光片171之间。所述光源与所述导光板172平行设置，所述光源位于所述导光板172远离所述遮光板140的一端。本实施中，两个显示屏的背光模组可以共同使用同一个反光片。
当所述移动终端100处于第一状态，即两个显示屏10的背面相对设置的时候，所述第二连接件160处于自然状态，不受力，且所述第二连接件160与所述复位柱130之间没有力的作用，所述复位柱130的一端依次穿过所述通孔141及所述第一侧边111上的贯穿孔1111，并伸出所述外壳110。
所述反光片171从所述连通窗120伸出，并绕过所述转轴20伸入另一显示屏的连通窗后收容于另一显示屏的背光模组中，所述反光片171与所述遮光板140相垂直方向上的两端可以与两个背光模组的导光板对齐，也可以多出两个背光模组的导光板。
在所述复位柱的130的卡合下，所述遮光板140拉伸所述第一连接件150，所述遮光板140远离所述顶壁112，并遮挡住所述连通窗120，所述背光模组170的胶框的底面靠近所述连通窗120的一端与所述遮光板140共同夹持所述反光片，以保证使所述连通窗120完全闭合，使得所述背光模组170不会漏光。
而当所述移动终端100从第一状态变化为第二状态时，即所述移动终端100从所述两个显示屏10的背面相对设置，通过翻转，两个显示屏10的显示面处于同一平面的时候，所述复位柱130受到与所述复位柱130相对的显示屏的第一侧边的压力，挤压所述第二连接件160，所述复位柱130向所述U形槽内移动，从而收回到所述外壳110中。
由于所述复位柱130的大部分收回到所述显示屏10中，所述顶柱132的剩余部分还位于所述通孔141及所述贯穿孔1111中，所述遮光板140没有了所述复位柱130的限位，并且所述遮光板140受到了所述第一连接件150的拉力。所述遮光板140在所述第一连接件150的带动下，朝所述顶壁112的方向平移，打开所述连通窗120，并暴露出所述背光模组170的反光片171以及至少部分导光板172。两个显示屏10的背光模组170通过所述连通窗120得以连通，形成一个公共背光模组，两个显示屏可以共同使用一个公共背光模组。
所述反光片171通过所述连通窗120位于两个背光模组中，由于使用一个公共背光模组以及一个反光片171，两个显示屏的背光光线均匀，亮度相同。
两个背光模组使用一个反光片171，还可以避免两个背光模组170连通时，光线从两个显示屏10的连接处溢出，造成背光的浪费。为了避免光线从两个显示屏10的连接处溢出，还可以在两个显示屏10对接的两个第一侧边111的外壳上，对应所述连接窗120的外围设置适配的凸壁和凹槽，使用凸壁和凹槽配合，使得两个显示屏10的连接处形成封闭的空间，以避免光线溢出。
每个显示屏10的内部还可以设置有收容装置，所述收容装置可以位于所述外壳110上与所述第一侧边111相对设置的侧边上，并且所述反光片171与所述连通窗120相垂直方向上的两端分别与所述收容装置连接，当两个显示屏10的显示面通过翻转处于同一平面时，所述反光片171在与所述连通窗120相垂直方向上的两端分别收容于所述收容装置中，且所述反光片171拉紧并平铺于所述公共背光模组的底部。
而当所述移动终端100从第二状态变化为第一状态时，即所述移动终端100从两个显示屏10的显示面处于同一平面，通过翻转，使所述两个显示屏10的背面变成相对设置的时候，所述复位柱130在所述第二连接件160的力的作用下，向外移动，直至所述切面131部分伸出所述外壳110停止，在此过程中，所述复位柱130上的切面131不断挤压所述通孔141的侧壁，使得所述遮光板 140向所述外壳110的底壁方向移动，直至所述遮光板140抵住所述反光片171为止，此时，所述移动终端100回到第一状态。
图6为本实施方式提供的一种背光源的控制方法的流程图。如图6所示，所述方法可以应用于上述实施例提供的移动终端100中，所述移动终端100的每个显示屏10的背光源包括第一光源组和第二光源组，所述第二光源组靠近两个显示屏10转动连接的一侧，所述方法包括以下步骤。
在步骤601中，检测所述移动终端是否处于大屏状态，其中，所述大屏状态为所述移动终端的两个显示屏通过翻转处于同一平面。
由于所述移动终端100具有两个显示屏10，用户可以使用其中一个显示屏10，还可以将两个显示屏10的显示面处于同一平面内，即使用所述移动终端100的大屏状态。看电影和办公时，可以使用大屏。
因此，在该步骤中，所述移动终端可以实时检测所述移动终端所处的状态，检测所述移动终端是否处于大屏状态。
在步骤602中，若所述移动终端处于大屏状态，控制两个显示屏中的一个显示屏的第二光源组不工作。
当将双屏移动终端的两个显示屏通过翻转，使得两个显示屏的显示面处于同一平面时，即双屏移动终端处于大屏状态时，双屏移动终端的显示尺寸相应变大。举例来讲，假设每个显示屏都为4英寸的屏，那么，当两个显示屏通过翻转，使得显示面处于同一平面后，双屏移动终端的显示屏变为6寸屏。一个4寸屏的背光源假设需要8颗背光灯，那么两个显示屏一共有16颗背光灯，但是一个6寸的显示屏只需要12颗背光灯，这样算来，相关技术中的双屏移动终端，如果使用相关技术中的背光方式的话，可能造成资源浪费，同时增大了移动终端的功耗，浪费电量。
而本实施方式中，当所述移动终端100处于大屏状态，即两个显示屏10通过翻转使显示面处于同一平面时，两个显示屏10的背光模组相互连通，共同一个公共背光模组，并且将每个背光模组中的背光源划分为第一光源组和第二光源组。
因此，该步骤中，当所述移动终端100处于大屏状态时，也就是所述移动终端处于第二状态，两个显示屏10通过翻转使显示面处于同一平面之后，所述移动终端100控制两个显示屏中一个显示屏10中的第二光源组不工作，既满足 了大屏状态下背光亮度的需求，降低了功耗，又延长了移动终端100的使用时间。其中，第二光源组不工作即第二光源组不被点亮。
在步骤603中，若所述移动终端未处于大屏状态，控制需要显示的显示屏中的第一光源组和第二光源组同时工作。
该步骤中，当所述移动终端100检测到所述移动终端100未处于大屏状态的时候，也就是说，两个显示屏10的背面相对设置，或者是两个显示屏10各自工作的时候，那么所述移动终端100可以控制需要进行显示的那个显示屏10工作，即控制需要显示的显示屏10中的第一光源组和第二光源组同时工作。其中，第一光源组和第二光源组同时工作即第一光源组和第二光源组均被点亮。
本实施例提供的移动终端及背光源的控制方法，所述移动终端包括两个显示屏以及两个连通窗，其中，所述两个显示屏通过转轴可转动连接，每个显示屏包括外壳及收容于所述外壳中的背光模组，每个显示屏的外壳的第一侧边上设置有连通窗，所述两个显示屏中的一个显示屏的第一侧边与所述两个显示屏中的另一显示屏的第一侧边通过所述转轴对接，当所述两个显示屏的显示面通过翻转处于同一平面时，每个显示屏的连通窗打开，两个背光模组相互连通形成一个公共背光模组，两个显示屏共用所述公共背光模组。
通过在两个显示屏对接的侧壁上设置连通窗，当所述两个显示屏的显示面通过翻转处于同一平面时，位于侧壁上的连通窗打开，使得两个显示屏的背光模组相通形成一个公共背光模组。经过背光板的传导和反光片的反射等，公共背光模组中的光线均匀分布，使得两个显示屏的背光模组中的光线量相同，从而使得两块显示屏的亮度一致。当两个显示屏的显示面处于同一平面时，可以控制两个显示屏中的一个显示屏的部分背光源工作，满足移动终端亮度需求，降低功耗，延长移动终端的使用时间。
上述实施例中的方法可以由中央处理器(Central processor)、数字信号处理器(Digital Signal Processor，DSP)或者现场可编程门阵列(Field Programmable Gate Array，FPGA)执行，中央处理器、DSP和FGPA可以集成在移动终端中。中央处理器、DSP和FGPA可以包含存储有可执行指令的计算机可读存储介质，所述可执行指令设置为执行上述方法。上述实施例方法的全部或者部分步骤可以通过程序指令相关的硬件来完成，所述的程序可以存储于一计算机可读取介质中，该程序在执行时，包括以下步骤：
检测所述移动终端是否处于大屏状态，其中，所述大屏状态为所述移动终端的两个显示屏通过翻转处于同一显示面；
若所述移动终端处于大屏状态，控所其中一个显示屏的第二光源组不工作；以及
若所述移动终端未处于大屏状态，控制需要显示的显示屏中的第一光源组合第二光源组同时工作。
所述的计算机可读存储介质可以是非暂态存储介质，如只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁碟或者光盘等多种可以存储程序代码的介质，也可以是暂态存储介质。
工业实用性
