Description

一种显示方法、移动终端及VR眼镜
本申请要求在2016年4月22日提交中国专利局、申请号为201610256767.X，发明名称为“一种显示方法、移动终端及VR眼镜”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及虚拟现实技术领域，尤其涉及一种显示方法、移动终端及VR眼镜。
背景技术
现有LCD(Liquid Crystal Display，液晶显示器)屏幕采用背光+液晶分子转动控制透过光强的方式，这个方式下，在一个像素显示周期，屏幕始终是亮的，因而应用到VR(Virtual Reality，虚拟现实)中时，由于图像在屏幕上停留时间长，而导致体验较差。
在VR使用中，如果屏幕的刷新率与现有的LCD显示屏的刷新率一样，则用户使用时会有比较明显的眩晕感。为解决上述问题，现有技术中一般使用OLED(Organic Light-Emitting Diode，有机发光二极管)屏幕替代LCD屏幕应用到VR中，由于OLED屏幕采用通过控制发光时间来控制亮度，因此OLED可以将60Hz的OLED屏幕等效于120Hz的屏幕。
但上述方式存在的问题是：该方式需要对移动终端的LCD屏幕或VR的LCD显示屏进行更换，势必会提高运营成本，并且在实际应用中，也无法与已有的移动终端配合使用。
综上所述，现有技术中亟需一种提高屏幕刷新率的方法。

附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简要介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域的普通技术人员来讲，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1为本发明实施例提供的VR眼镜结构示意图；
图2为本发明实施例提供的显示方法流程图；
图3为本发明实施例提供的显示方法详细流程图；
图4为本发明实施例提供的显示方法流程图；
图5为本发明实施例提供的显示方法详细流程图；
图6为本发明实施例提供的VR眼镜示意图；
图7为本发明实施例提供的移动终端示意图；
图8为本发明实施例提供的VR眼镜示意图。
具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
如图1所示，为本发明实施例提供的VR眼镜结构示意图，其中包含显示 装置101，主动式快门器件102，可选地，还可以包含透镜103、反射镜等器件。其中，当VR眼镜是一个VR盒子时，显示装置101是一个可以放置移动终端(如手机等)的结构，通过将移动终端放置于显示装置101中进行播放发，用户通过眼睛104观看显示装置101中的移动终端的屏幕；当VR眼镜自带显示屏幕时，显示装置101则是一块显示屏，此时VR眼镜可以直接通过VR眼镜中的显示屏来播放图像，无需在VR眼镜中放置移动终端，同样地，用户通过眼睛104观看显示装置101，即观看显示屏。
在现有技术中，VR眼镜是不带主动式快门器件102的，因此用户通过眼睛104是直接观看到显示装置101的，当显示装置101的屏幕是LCD屏幕时，LCD屏幕是持续发亮的。
而在本发明实施例中，在加入了主动式快门器件102后，可以控制主动式快门器件102周期性地打开或者关闭，从而使得显示装置101中的光路产生了通断效果，进而提高了屏幕的刷新率，例如，以60hz的刷新率为例，一帧图像的时间约为16.7ms，主动式快门器件在一帧的第4ms时开启，持续开启8ms后关闭，由于在一帧图像之内，图像刷新的次数提高了一倍(即由原来的1次变为现在的2次)，因此人眼的感觉是120hz的刷新率，实际图像和全黑图像交替进行。从而，本发明的方法可以通过在屏幕与人眼之间的光路上增加主动式快门器件，通过控制主动式快门器件的通断，从而提高屏幕刷新率。
可选地，所述主动式快门器件位于所述移动终端的屏幕与所述VR眼镜的透镜之间且靠近于所述移动终端的屏幕，所述主动式快门器件在闭合状态时覆盖所述移动终端的屏幕。
需要说明的是，本发明实施例中，对于主动式快门器件在一帧图像中的打开时间和关闭时间都是可以调整的。另外主动式快门器件主要是高速LCD光阀，并且任何可以快速控制光路通断的器件也都可以用作主动式快门器件。主动式快门器件的主要用途是：当主动式快门器件打开时，光可以通过主动式快门器件，当主动式快门器件关闭时，光不能通过主动式快门器件，例如， 在本发明中，当将主动式快门器件置于用户眼镜与显示装置之间时，可以通过控制主动式快门器件的打开，实现控制显示装置的光能够通过主动式快门器件使人眼可见，以及控制主动式快门器件的关闭，实现控制显示装置的光无法通过主动式快门器件使人眼不可见。
下面结合说明书附图对本发明实施例作进一步详细描述。
在本发明实施例中，VR眼镜可以有两种类型，第一种类型是VR眼镜是一个VR盒子，则需要在显示装置101中放置移动终端，通过移动终端播放图像，例如播放视频等；第二种类型是VR眼镜自带显示屏幕，此时显示装置101是一个显示屏，VR眼镜可以通过无线或者有线的方式连接服务器，因而VR眼镜可以直接通过接收服务器发送过来的图像数据，并通过显示屏进行播放，因而无需再VR中放置移动终端。
下面对上述两种类型的VR眼镜使用本发明实施例提供的显示方法进行分别介绍。
一、VR眼镜是一个VR盒子，需要在VR眼镜中放置移动终端的情形
如图2所示，本发明实施例提供的显示方法，包括：
步骤201、VR眼镜接收移动终端发送的同步信号，所述同步信号为所述移动终端收到启动图像显示指示后发送的；
步骤202、所述VR眼镜根据所述同步信号启动所述VR眼镜中的主动式快门器件；所述主动式快门器件位于所述移动终端的屏幕侧；
步骤203、根据所述移动终端显示每帧图像的周期，所述主动式快门器件周期性地打开或关闭，以使所述移动终端显示的图像周期性地透过所述主动式快门器件。
参照图1所示的VR眼镜结构，VR眼镜中包含主动式快门器件，显示装置放置有移动终端，所述主动式快门器件只要位于用户的眼睛与所述移动终端之间都可以。例如，VR眼镜中包含一个显示装置和多个透镜，在主动式快门器件可以在多个透镜中任意两个透镜之间，也可以是在靠近人眼的透镜与人眼之间，也可以是在靠近显示装置的透镜与显示装置之间，只要是主动式 快门器件位于人眼与移动终端的屏幕之间就可以，并且从用户的眼镜在看移动终端的屏幕时，主动式快门器件的大小应该至少能够完全或者接近完全覆盖移动终端的显示装置。
由于主动式快器件是一种平面结构，而移动终端屏幕也是一种平面结构，因此在实际应用中，优选地，将主动式快门器件放置于靠近手机屏幕放置的位置，即所述主动式快门器件位于所述移动终端的屏幕侧。
移动终端在收到启动图像显示指示后，发送扫描信号至所述移动终端的屏幕以显示图像，以及将扫描信号中的同步信号发送至VR眼镜中，其中发送的方式可以是通过有线连接的方式，也可以是通过蓝牙等无线方式。
VR眼镜接收移动终端发送的同步信号，根据所述同步信号启动所述VR眼镜中的主动式快门器件，以及根据移动终端显示每帧图像的周期，所述主动式快门器件周期性地打开或关闭，从而使得移动终端显示的图像周期性地透过所述主动式快门器件，其中，移动终端的屏幕为LCD屏幕，根据本发明实施例提供的方法，其实际效果类似于OLED屏幕的效果，OLED屏幕在一个像素周期中，是部分时间亮的，部分时间不亮，而本发明实施例中移动终端的LCD屏幕是一直亮着的，但由于主动式快门器件时周期性地打开或关闭，因此人眼所看到的LCD屏幕发出的光实际上也是部分时间亮着，部分时间不亮的，从而本发明实施例通过增加主动式快门器件，将LCD屏幕实现了类似于OLED屏幕的效果，其由于提高了屏幕刷新率，改善了人眼可见的时延特性，可以显著降低VR使用者感到眩晕的可能性，从而提升了用户使用体验。
具体地，主动式快门器件周期性地打开或关闭的方式有很多种，下面例举两种进行说明：
一、所述主动式快门器件在所述移动终端的每帧图像的显示时间内打开一次且关闭一次
例如，所述主动式快门器件在每帧图像的显示时间内的设定时间打开，持续设定时长后关闭；所述设定时长大于或等于一帧图像显示时长的四分之一。
举例来说，移动终端的屏幕刷新率为60Hz，即一帧图像的周期为16.7ms，可以控制主动式快门器件在一帧图像开始后4ms打开，然后持续打开8.7ms后，关闭主动式快门器件，这样的话，由于移动终端的屏幕持续发出的光在人眼看来，增加了一倍的刷新次数(因为在一帧图像中增加了两次变化的动作，即一次打开主动式快门器件，导致光可以透过，一次关闭主动式快门器件，导致光不能透过)，因而导致刷新率由60Hz变成了120Hz，减少了用户观看的眩晕感，同时由于移动终端的屏幕持续发出的光有四分之一的时间是透过了主动式快门器件，因而可以保证用户看到的屏幕的亮度不会受太多影响。
二、所述主动式快门器件在所述移动终端的每帧图像的显示时间内打开两次且关闭两次
在该方法中，可以使得人眼感觉到的屏幕刷新率提高四倍，例如原来的屏幕刷新率为60Hz，则通过该方法，可以将刷新率提高到240Hz，不过也需要尽量控制人眼观看的移动终端屏幕透过的光不能太少，否则会影响观看效果。
当然，还可以有更多的控制主动式快门器件的方法，在此不一一赘述。
本发明实施例提供的方法，通过在VR眼镜的光路中放置主动式快门器件，VR眼镜接收移动终端发送的同步信号，根据所述同步信号启动VR眼镜中的主动式快门器件，使得主动式快门器件根据移动终端显示每帧图像的周期，周期性地打开或关闭，使得移动终端显示的图像周期性地透过所述主动式快门器件，因而人眼所看到的移动终端中图像类似与OLED中的图像，周期性地发光及不发光，因而实现了在无需更换LCD屏幕的情况下，达到了与OLED屏幕相同的显示效果，一方面提高了屏幕刷新率，减少了用户观看时的眩晕感，另一方面降低了现有技术更换OLED屏幕的成本。
如图3所示，为本发明实施例提供的显示方法详细流程图，包括：
步骤301、VR眼镜接收移动终端发送的同步信号，所述同步信号为所述移动终端收到启动图像显示指示后发送的；
步骤302、所述VR眼镜根据所述同步信号启动所述VR眼镜中的主动式快门器件；所述主动式快门器件位于所述移动终端的屏幕与所述VR眼镜的透镜之间且靠近于所述移动终端的屏幕，所述主动式快门器件在闭合状态时覆盖所述移动终端的屏幕；
步骤303、所述主动式快门器件在每帧图像的显示时间内的设定时间打开，持续设定时长后关闭；所述设定时长大于或等于一帧图像显示时长的四分之一，以使所述移动终端显示的图像周期性地透过所述主动式快门器件。
本发明实施例提供的方法，通过在VR眼镜的光路中放置主动式快门器件，VR眼镜接收移动终端发送的同步信号，根据所述同步信号启动VR眼镜中的主动式快门器件，使得主动式快门器件根据移动终端显示每帧图像的周期，周期性地打开或关闭，使得移动终端显示的图像周期性地透过所述主动式快门器件，因而人眼所看到的移动终端中图像类似与OLED中的图像，周期性地发光及不发光，因而实现了在无需更换LCD屏幕的情况下，达到了与OLED屏幕相同的显示效果，一方面提高了屏幕刷新率，减少了用户观看时的眩晕感，另一方面降低了现有技术更换OLED屏幕的成本。
二、VR眼镜自带显示屏的情形
如图4所示，为本发明实施例提供的显示方法，包括：
步骤401、VR眼镜包括处理器、显示屏、主动式快门器件及透镜，所述主动式快门器件位于所述显示屏靠近所述透镜的一侧；所述处理器接收到启动图像显示指示后，发送扫描信号至所述显示屏以显示图像并发送同步信号至所述主动式快门器件；
步骤402、根据所述同步信号及所述显示屏显示每帧图像的周期，所述主动式快门器件周期性地打开或关闭，以使所述显示屏显示的图像周期性地透过所述主动式快门器件。
在第二种情形中，VR眼镜自带显示屏，因此不需要通过移动终端播放图像，而是可以通过与VR眼镜进行有线或无线方式连接的服务器发送启动图像显示指示到VR眼镜的处理器，处理器在接收到启动图像显示指示后，发送扫 描信号至VR眼镜的显示屏，从而使得显示屏可以显示图像，同时处理器将扫描信号中的同步信号发送至主动式快门器件，主动式快门器件在接收到同步信号后，根据所述同步信号及所述显示屏显示每帧图像的周期，进行周期性地打开或关闭，从而使得所述显示屏显示的图像周期性地透过所述主动式快门器件。
参照图1所示的VR眼镜结构，VR眼镜中包含主动式快门器件，显示装置放置为一个显示屏，所述主动式快门器件只要位于用户的眼睛与所述移动终端之间都可以。例如，VR眼镜中包含一个显示屏和多个透镜，在主动式快门器件可以在多个透镜中任意两个透镜之间，也可以是在靠近人眼的透镜与人眼之间，也可以是在靠近显示屏的透镜与显示屏之间，只要是主动式快门器件位于人眼与显示屏之间就可以，并且从用户的眼镜在看显示屏时，主动式快门器件的大小应该至少能够完全或者接近完全覆盖显示屏。
由于主动式快器件是一种平面结构，而显示屏也是一种平面结构，因此在实际应用中，优选地，将主动式快门器件放置于靠近显示屏的位置，因而所述主动式快门器件在闭合状态时覆盖所述显示屏。
该情形下，对于主动式快门器件打开或关闭的方式可参照情形一中的方法，即主动式快门器件周期性地打开或关闭的方式有很多种，例如有以下两种方式：
一、所述主动式快门器件在所述显示屏的每帧图像的显示时间内打开一次且关闭一次。
例如，所述主动式快门器件在每帧图像的显示时间内的设定时间打开，持续设定时长后关闭；所述设定时长大于或等于一帧图像显示时长的四分之一。
二、所述主动式快门器件在所述显示屏的每帧图像的显示时间内打开两次且关闭两次
对于上述两种方式下主动式快门器件打开或关闭的具体方式可参照情形一下的详细介绍，在此不再赘述。
