Description

一种显示屏开合角度的调节方法及多屏终端 技术领域
本发明涉及通信技术领域，尤其涉及一种显示屏开合角度的调节方法及多屏终端。
背景技术
随着智能移动终端的快速发展，越来越多的移动智能终端具有多显示屏。在利用具有多显示屏的移动智能终端进行应用显示时，各个显示屏可以显示相同内容的不同部分，也可以显示不同的内容，例如，对于现有的双屏幕移动终端(如双屏幕手机)，用户可以独立操作两个显示屏幕，即双屏可以用于分别看电视、听音乐、上网等，一机多用。
现有的移动终端在强光环境下，通常通过提高屏幕亮度的方法来保证显示效果。然而，由于多屏终端采用不只一块屏幕进行显示，本身耗电严重，如果仍然通过提高屏幕亮度的方法来保证显示效果，功耗问题更加严重。
发明内容
为了解决上述技术问题，本发明实施例提供了一种显示屏开合角度的调节方法及多屏终端，能够改善多屏终端的显示效果且不加重多屏终端的功耗。
为了达到本发明目的，本发明实施例的技术方案是这样实现的：

多屏终端检测各显示屏的环境光线强度和对应的光线入射角度，并获取当前使用的显示屏以及所述当前使用的显示屏与使用者的视点角度；
多屏终端判断与所述视点角度差值最小的光线入射角度所对应的环境光线强度是否大于预设值，如果大于预设值，多屏终端调节各显示屏之 间的开合角度，直至多屏终端判断出与当前视点角度最接近的光线入射角度所对应的环境光线强度小于或等于预设值。
本发明实施例还提供了一种多屏终端，包括检测模块、处理模块和调节模块，其中：
检测模块，设置为检测各显示屏的环境光线强度和对应的光线入射角度，并获取当前使用的显示屏以及当前使用的显示屏与使用者的视点角度，将检测到的环境光线强度和光线入射角度以及获取的视点角度输出至处理模块；
处理模块，设置为比较与所述视点角度差值最小的光线入射角度所对应的环境光线强度与预设值的大小，如果大于预设值，发送第一通知至调节模块；如果小于或等于预设值，发送第二通知至调节模块；

在本发明实施例中，还提供了一种存储介质，该存储介质可以存储有执行指令，该执行指令用于执行上述实施例中的显示屏开合角度的调节方法的实现。
本发明实施例的技术方案，具有如下有益效果：
本发明实施例提供的显示屏开合角度的调节方法及多屏终端，通过调节使用者当前使用的显示屏与其它显示屏的开合角度，使得与当前视点角度最接近的光线入射角度所对应的环境光线强度小于等于预设值，进而使得使用者感受到的显示屏反光程度最小，克服了现有技术在强光线下必须提高亮度增加功耗来保证显示效果的弊端，改善了多屏终端的显示效果且不加重多屏终端的功耗。

值得说明的是，所述预设值可以在终端出厂前预先设定或者由使用者设置。当当前使用的显示屏的反光度越小时，或者使用者习惯与当前使用的显示屏之间的距离越近时，使用者感受到的反光强度越小，所述预设值可以设的越大。所述终端的各个显示屏之间设有转轴，转轴上设有电机，通过控制电机转动调节各显示屏之间的开合角度。

进一步地，检测模块201通过摄像头获取当前使用的显示屏以及所述当前使用的显示屏与使用者的视点角度。
进一步地，在所述处理模块202判断出所述环境光线强度大于所述预设值之后且发送第一通知至调节模块203之前，所述处理模块202在当前使用的显示屏上，给出是否需要调节各显示屏之间的开合角度的提示，如果需要调节，则发送第一通知至调节模块203。
以下通过一个优选实施例，说明如何应用本发明的显示屏开合角度的调节方法和终端。值得注意的是，以下的优选实施例只是为了更好的描述本发明，并不构成对本发明不当的限定。
如图3所示的一种双屏移动终端，左右方向可0°-180°折叠，其中301定义为副屏，其上设计有检测环境光线强度和光线入射角度的传感器以及检测使用者当前使用的显示屏及视点角度的摄像头；303定义为主屏，其上设计有检测环境光线强度和光线入射角度的传感器、以及检测使用者当前使用的显示屏及视点角度的摄像头；302定义为连接装置，连接主屏和副屏各种功能，并设计有电机，所述电机可以使终端的显示屏自动旋转。
如图4所示，主屏和副屏都采用红外或RGB等光线类传感器检测，实时采集当前主屏和副屏的光线强度和光线入射分布；
具体的，在实际应用环境中，光线入射比较复杂，一般都是如图4所示的多种角度多种强度的光线杂合在一起。本实施例示意一种列表优选法，如表1所示，从高到低，通过光强或照度等级排列，记录各级光线的入射角度。
光强或照度等级 光强或照度 入射角度
第一级 8000勒克斯lx 30度
第二级 3000勒克斯lx 48度
… … …
第N级 1000勒克斯lx 86度
表1
需要说明的是，光照强度是一种物理术语，指单位面积上所接受可见光的光通量，简称光强或照度，单位勒克斯(Lux或Lx)，用于指示光照的强弱和物体表面被照明的程度的量。
开启主屏和副屏的摄像头，采集使用者双眼与终端的相对位置，获取使用者当前使用的显示屏以及所述显示屏与使用者的视点角度，判断人眼落入哪一级光线的反射范围内。假设使用者当前使用的显示屏与使用者的视点角度为40°，则与当前视点角度最接近的入射角度为48度，即人眼落入的光强等级为第二级，如表2所示。
光强或照度等级 光强或照度 入射角度 人眼落入
第一级 8000勒克斯lx 30度 否
第二级 3000勒克斯lx 48度 是
… … … …
第N级 1000勒克斯lx 86度 否
表2
将第二级的光强与预设值进行比较，判断当前使用者感受到的屏幕表面反光程度。通常，根据手机的显示屏的材质的不同以及使用者使用习惯的不同(例如，使用者眼睛距离显示屏的远近距离不同，感受到的反光程度不同)，所述预设值也不尽相同，例如，可以将所述预设值设为800勒克斯至1000勒克斯之间。具体的，如表2所示，假使当前落入第二高强度光线内，第二级的光强为3000勒克斯，大于所述预设值，判断用户感受到明显反光，需要改善。
根据上述采集到的数据以及上述判断，计算终端更优的姿态，更优指的是：更好的显示效果、同时不增加屏幕亮度。
具体的，更优姿态的判断，目的是使人眼落入更低光强或照度级，如表3所示。计算当前姿态与更优姿态之间的姿态差异，例如最重要的开合角度。

表3
为用户提供几种优化方案，由用户选择。比如：给出是否可以自动调节当前显示屏与其它显示屏的开合角度，以拥有更好的显示效果且不增加亮度和功耗的提示。
如果使用者选择自动调节当前显示屏与其它显示屏的开合角度，则:
确定目标开合角度，计算方式由上述可以得出；检测当前开合角度，确定与目标开合角度的差异，控制电机自动调节当前显示屏的开合角度，最终达到目标开合角度。
本发明提供的显示屏开合角度的调节方法及多屏终端，通过调节使用者当前使用的显示屏与其它显示屏的开合角度，使得与当前视点角度最接近的光线入射角度所对应的环境光线强度小于等于预设值，进而使得使用者感受到的显示屏反光程度最小，克服了现有技术在强光线下必须提高亮度增加功耗来保证显示效果的弊端，改善了多屏终端的显示效果且不加重多屏终端的功耗。
本申请所述技术方案不限于有线设备或无线终端，可以是工控显示终 端、便携产品或其它车载可视设备，且方案可靠、成本低廉。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序来指令相关硬件完成，所述程序可以存储于计算机可读存储介质中，如只读存储器、磁盘或光盘等。可选地，上述实施例的全部或部分步骤也可以使用一个或多个集成电路来实现，相应地，上述实施例中的各模块/单元可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。本发明不限制于任何特定形式的硬件和软件的结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
工业实用性
本发明实施例提供的显示屏开合角度的调节方法及多屏终端，通过调节使用者当前使用的显示屏与其它显示屏的开合角度，使得与当前视点角度最接近的光线入射角度所对应的环境光线强度小于等于预设值，进而使得使用者感受到的显示屏反光程度最小，克服了现有技术在强光线下必须提高亮度增加功耗来保证显示效果的弊端，改善了多屏终端的显示效果且不加重多屏终端的功耗。
